This is where the scaphoid and the lunate bones in the wrist articulate with their respective fossa at the distal radius [2]. A positive test (meaning you may have a TFCC injury) is a specific pinch pain along the ulnar (pinky) side of the joint. During pronation, the ulna moves dorsally (to the back of the wrist) to provide additional stability to the DRUJ. Osterman AL, Terrill RG. Piano Key Sign: Prominent distal ulna with full pronation 3. Save my name, email, and website in this browser for the next time I comment. I am not sure if the weak or tight muscle contributes to the injury or if the injury contributes to the tight and weak muscles. This involves some manipulation to see the extent and location of pain and immobility. The TFCC compression test is positive if axial loading of the ulnar side of the hand with ulnar deviation of the wrist results in significant pain. The Sports Physiotherapist.Retrieved from http://www.thesportsphysiotherapist.com/triangular-fibrocartilage-complex-tears-evidence-based-assessment-and-management/, [6] Thomas BP, Sreekanth R. Distal radioulnar joint injuries. Studies show that MRIs can have an 86% sensitivity for detecting TFCC tears or lesions [6]. Repeat 3 times. The best way to palpate the TFCC is with the wrist in pronation. Supination test: Patient grabs the underside of a table with the forearms supinated; this causes a load on the TFCC and dorsal impingement, which will cause pain if there is a peripheral, dorsal tear. The torn portion can become pinched in the wrist joint with motion, causing pain and clicking. Once the extent of the injury is known, a decision can be made regarding the best treatment options. 1991 May. These are divided into superficial and deep components. Make sure you choose a good quality kinesiotape to avoid any skin irritations. The second piece of the DRUJ is the articulation of the proximal carpal row distal end of the radius. The wrist in placed in ulnar deviation and the clinician provides a “compression” or sheer force through the ulnar side of the wrist. They may then perform a physical examination of the wrist area. The first component of the DRUJ is the articulation of the ulnar notch of the radius and the distal end of the ulna. Having an acupuncturist evaluate your symptoms is important. As such, TFCC pathology is a common cause of ulnar sided wrist pain. It can be tricky because often a subluxating ECU is the result of an underlying TFCC tear. An X-ray may be performed to check for fractures and other abnormalities. The test is sensitive and examines the presence (or absence if negative) of ulnar fovea disruption. Abstract. Tenderness with palpation may indicate a TFCC injury. MRI Showing TFCC Tear. History and etymology. The TFCC is a combination of ligaments (that connect bone to bone) and fibrocartilage (tough tissue that protects the ends of bones) located at the end of the forearm bone on the pinky side (called the ulna). There are many treatments available to help. The supinator and pronator muscles are often imbalanced in TFCC tears. Triangular Fibrocartilage Complex (TFCC) Degeneration/Tears. If the TFCC displaces upwards and radially, this indicates a tear of foveal insertion of the TFCC or pc-TFCC tear. Neck stretching (C5-T1 cervical spine) is important. IF your weight-bearing tolerance is below 45 lbs, you will be spinning your wheels on the treatment of the ECU. During assessment, the clinician should also assess the interosseous membrane and the extensor carpi ulnas tendon. Damage to this area of the TFCC typically results in a lesion or tear that is treated by debridement. Click here to head over to our resources section and check out our variety of clinical and professional resources aimed at increasing your knowledge and skills. Similarly, de Araujo et al. The Radius Pull Test can be used to assess the longitudinal forearm stability provided by the interosseous membrane. Ulnar-sided wrist pain, clicking or popping indicate a positive test [7]. Ulnar-sided wrist pain indicates a positive test. Your email address will not be published. It is important to know that two types of tears can occur in your TFCC. Arthroscopy. Volar and Dorsal Radioulnar Ligaments (RUL). Dr. Tsourmas shows the proper way to diagnose a TFCC Tear in the wrist. *distal radioulnar joint stability clinically assessed by the ulnar fovea sign and ballottement test. You can calm things down with ice, cortisone injection (it usually does not help with TFCC but can be very helpful to the ECU), deep tissue massage, acupuncture, herbal and diet changes, cupping, dry needling, kinesiotaping, and stretching. Make sure you choose a good quality kinesiotape to avoid any skin irritations. The test results you get from performing the Weight Bearing Test indicate whether your injury is injured. It can be tricky because often a subluxating ECU is the result of an underlying TFCC tear. During pronation, the dorsal superficial and deep palmar ligaments tighten and the palmar superficial and deep dorsal ligaments loosen. It suspends the carpal bones on the ulnar side of the wrist (lunate and triquetrum) from contacting the distal ulna and radius. The first is a traumatic tear, which occurs because of an injury. Lee Master D, Yao J. Notice any areas that are painful and as they improve. If your symptoms suggest that you have a TFCC tear then a MRI (Magnetic Resonance Imaging test) is the best type of scan to confirm and assess the diagnosis. It's responsible for the dreaded tennis elbow. All of these areas are impacted with TFCC injuries. If the radial nerve is pinched at the neck or on its path to the hand, it will not conduct electricity to the distal muscles well. TFCC functions to stabilize the distal radioulnar joint, and provide shock absorption between the ulna and the carpus It is the first type of tear that more commonly occurs among athletes. The final extrinsic stabilizer of the DRUJ is the tendon of the Extensor Carpi Ulnaris (ECU). The Brachioradialis muscle also gets weak in this injury. Take a look at the path of the radial nerve and determine if it is tight anywhere along its path. The most important thing to understand is your weight-bearing tolerance. They may then perform a physical examination of … To diagnose a TFCC tear, a doctor will usually begin by asking the person about their symptoms and medical history. To understand the ECU better - please watch this short video. The purpose of this study is to describe the use of a novel brace as a non-surgical intervention for TFCC tears. *distal radioulnar joint stability clinically assessed by the ulnar fovea sign and ballottement test. This is particularly useful during gripping movements, which tend to apply an axial force, bringing the ulna close towards the carpal bones [2]. What is a tear or sprain of the TFCC? What are the implications of a TFCC tear? Falling on an outstretched hand; Process of aging can cause wear and tear of the soft tissues. As mentioned, ECU Tendonitis is along the Small Intestine Median - which is related to having GI issues. These two tend to be the most common alternatives to a TFCC injury [4] [7]. Lunotriquetral interval tenderness 5. DOI: 10.2174/1874325001206010204, Your email address will not be published. ©2017 by Rehab U Practice Solutions. This test has defined stability based on age, height and bone density. TFCC-Tränen werden häufig mithilfe des Fovea-Tests diagnostiziert, der auch als Ulnarfovea-Zeichen bezeichnet wird. NERVE GLIDING - Posterior Interossei Nerve (PIN). After ruling out potential alternative causes for ulnar-sided wrist pain and/or instability at the DRUJ, physical assessment of the TFCC should become the focus. Methods: This paper is a case study of a subject with a magnetic resonance imaging-confirmed TFCC tear. The TFCC compression test: The client maintains the flexed elbow position on a flat surface. In this case, you need to protect the wrist with a wrist splint at night to prevent stretching of the ECU and further irritation. She has also developed a conservative management protocol for the treatment of TFCC tears after 12 years of research around the globe. http://what-when-how.com/treatment-of-pain-with-chinese-herbs-and-acupuncture/wrist-pain-treatment-of-pain-with-chinese-herbs-and-acupuncture-part-1/, This has gained a lot of attention because it is helpful. This movement or translation of the ulna is made possible by the tightening and loosening of the radioulnar ligaments (RUL) of the TFCC. The second is a degenerative or chronic tear. Unlike X-rays, an MRI shows soft tissue structures, allowing assessing physicians to visualize the structures of the TFCC to determine whether or not a tear or lesion is present. An MRI is the optimal test to confirm the diagnosis when a fracture is not clear on simple x-ray. Stretch slowly and gently daily. The clinician stabilizes the distal radius/ulna with one hand and with the other hand, grabs the patients’s hand at the metacarpals (like a handshake). (OBQ13.65) A 30-year-old male laborer sustained a right wrist injury 9 months ago. The current literature contains no reports of treatment options other than surgery following failed conservative management of a triangular fibrocartilage complex (TFCC) tear. Read it here! Jul 5, 2018 | Blog, Clinical Resources, Education, Evidence Based Practice. In summary, rehabilitation for TFCC injury should consist of enough resting, appropriate protection, additional supports and strengthening exercises. Triangular fibrocartilage complex (TFCC) injuries may be traumatic or degenerative in nature.The TFCC is a complex structure consisting of the triangular fibrocartilage (TFC) disc proper, ulnomeniscal homologue and numerous ligaments and tendons. An MRI is performed and shows a triangular fibrocartilage complex (TFCC) injury. C. Shaver is inserted into the wrist joint to trim away the torn edges of the TFCC tear (like a lawn mower). A negative test (no injury) is reaching the end of the motion without pain or motion loss. You can do this all day long. The TFCC keeps the forearm bones (radius and ulna) stable when the hand grasps or the forearm rotates. In 100% of the cases I have seen, every TFCC tear presented with painful and diminished weight bearing tolerance. Palmer classification: helps for accurate recognition and diagnosis of TFCC injuries, however, injuries outside this classification system can occur 2. To understand the clinical anatomy of the TFCC, we must first review the structures of the distal radioulnar joint (DRUJ). Share any additional resources that you found helpful in the comments below! The triangular fibrocartilage complex (TFCC) is a cartilage structure located on the small finger side of the wrist that, cushions and supports the small carpal bones in the wrist. Typical tests that are done to determine a TFCC tear for a possible diagnosis is a palpation test called the Fovea Sign, which manipulates and isolates a pain location between the ulna and flexor carpi ulnaris. An X-ray may also be used to rule out fractures. Arthrography is positive for a TFCC tear if the dye leaks into any of the joints. Available from: http://www.ijoonline.com/text.asp?2012/46/5/493/101031, [7] Wijffels M, Brink P, SchipperI. Arthroscopic treatment of TFCC lesions. Wall Push-up is a good gentle weight-bearing exercises for TFCC rehabilitation, try to hold for 5 seconds for each repetition, 10 reps x 3 sets / day. Stabilization for the DRUJ is provided by both extrinsic and intrinsic structures. Either way, both of these muscles should be examined closely. 30 (4):451-5. . Zu diesem Zweck übt Ihr Arzt Druck auf die Außenseite Ihres Handgelenks aus und fragt Sie, ob Sie Schmerzen oder Druckempfindlichkeit verspüren. Finally the Extensor Carpi Ulnaris Test can be used to determine whether there is a dysfunction or injury at the ECU tendon. ... all the pains were gone and I went back to the hospital for another test and I was tested negative to the disease. extensor carpi ulnaris tendinopathy (including tendinosis, tear and/or instability) ulnar collateral ligament injury; ganglion cyst formation (may be soft tissue or intraosseous) Classification. Stretching is a very important facet of wrist injury recovery. All you need is a piece of ice and 2 minutes of direct massage to these areas. Side Note: Ulnar variance refers the location of the distal ulna in relation to the distal radius. The wrist can bend back and forth, side to side, and rotate. The TFCC also connects the ulna to the solar aspect of the carpus, which provides additional anterior stability. An MRI scan is most effective at diagnosing this particular injury with a 90% accuracy rate. This test has defined stability based on age, height and bone density. No strengthening until you have at least 65# of weight-bearing ability. (found online, at pharmacies, and large stores). The TFCC also provides some translational movement of the ulna during pronation and supination [7]. TFCC tears are diagnosed through careful examination of the wrist. Then perform ulnar deviation (tilt the hand toward the pinky) slowly. He has experience in a variety of rehab settings, working with patients recovering from a variety of injuries and surgeries. Such injuries can cause the subsheath to tear and the ECU to move out of its groove - causing a popping sensation as it rolls on the ulna. On MRI, a normal TFCC is a black band of tissue connecting the radius and ulna bones. Here are simple and very effective Radial Nerve stretches. It's important to gently stretch the ECU without causing TFCC pain. Join the group here. How do you Treat it? The ECU tendon helps maintain the wrist's mobility and stability. You can compare strength and stretch to the other arm and determine if they are involved. triangular fibrocartilage complex (TFCC) triangular fibrocartilage complex (TFCC) injury triangular fibrocartilage complex (TFCC) triangular fibrocartilage complex (TFCC) injury It is the continuation of the deep branch of the radial nerve after this has crossed the supinator muscle. Right: x-ray from Radiopaedia.org showing a relatively long ulna bone compared to the radius bone. The extrinsic stabilizers —those that originate outside of the DRUJ— provide much needed stabilization along the length of the radius and ulna [7]. Weight Bearing Test is the Best way to know to test if you have a TFCC tear. The Clunk Test for the forearm may indicate that the interosseous membrane is not providing support between the radius and the ulna. The purpose of this study is to describe the use of a novel brace as a non‐surgical intervention for TFCC tears. Often there is no visible swelling with ECU and TFCC tears. The hook test assesses the pc-TFCC and is performed by applying radial traction to the ulnarmost border of the TFCC. The PIN is a branch of the radial nerve which starts at the neck. Because the TFCC connects, protects and cushions the wrist and hand while gripping, a TFCC tear or TFCC injury can lead to chronic pain unless properly treated. See also. Pain on Weight Bearing The pronator gets tight, the supinator gets weak. Oftentimes, the entire muscle system gets tight and irritated - from wrist to elbow. The Chinese MD's describe the ECU along the Small Intestine Meridian. Zum Vergleich machen sie dasselbe mit Ihrem nicht betroffenen Handgelenk. Type 2 Tears – these are the degenerative type of tears that occur over a period of time as the body ages. Avoid putting an ice pack on your arm. The treatment option that is selected impacts the rehabilitation clinician’s approach to treating patients with a TFCC injury or tear. A positive ulnar fovea sign test is indicative of foveal disruption of the distal radioulnar ligaments and ulnotriquetral ligament injuries. The TFCC load test may reveal TFCC tears, though the pain may arise from ulnar abutment or chondromalacia of the hamate. Often after TFCC tear or injury, the patient must undergo weight and stress tests to determine the severity of the injury. The purpose of this article is to address the patients that have a TFCC injury AND an ECU subluxation. The main role of the TFCC is to provide stability to the DRUJ during rotational movements, such as pronation and supination [7]. This classification of peripheral triangular fibrocartilage complex (TFCC) tears has been first described by Andrea Atzei 1-3. 1 The triangular fibrocartilage complex (TFCC) is a fibrocartilaginous structure located on the ulnar side of the wrist. a tear in the TFCC typically occurs after a fall on an outstretched hand, but can also be degenerative in origin 1,3,4. The TFCC is a complex structure, as its name implies. As I’m sure you are aware, the typical DRUJ possesses approximately 180 degrees of rotational movement: 90 degrees from neutral to full supination, and 90 degrees from neutral to full pronation. It plays a crucial role in providing anterior stability to the DRUJ. If you are taking a shower, it is good to run cold water on the arm for a minute followed by heat for 4 minutes. Once you have the WristWidget® fitted … Repetitive motions in sports, athletic training or work setting can aggravate an already painful injury to the point that it becomes chronic. The patient is asked to place his/her hands down on a chair while sitting. Add Minerals to diet (magnesium, potassium, and sodium are important), in the forearm. A loss of the trampo-line eff ect is seen in complete avulsion injuries of the It crosses from the lateral epicondyle of the humerus and inserts at the base of the 5th metacarpal. It is mostly dependent on the location of the styloid process of the ulna. He also has experience as an adjunct faculty instructor at Augusta University’s Occupational Therapy Program, as a Licensed Board Member on the GA State OT Board, has served on several committees for the national OT Board (NBCOT), and as a consultant for the State of Georgia. This can be clearly seen and palpated when the hand is fully pronated (palm down). We have found that patients who have a TFCC tear often develop symptoms in their ECU. Treatment. 2014 Apr. Degenerative or chronic TFCC tears occur when the cartilage wears down as you age. If you have an ECU-only injury, please consult your hand therapist for guidance. There are three specific joint areas tested, so this test is called a triple injection wrist arthrogram. The therapist places one hand on the distal radius and ulna to provide stabilization, with the other hand holding the client’s hand (looking like a handshake) (Rehab Solutions, 2018). You can palpate the TFCC by placing a finger on the ulnar side of the wrist, on the solar surface, just distal to the ulna. Since the ECU tendon blends with the TFCC, an injury to this tendon can present in the clinic looking like a TFCC injury [6] [7]. The Clinical Syndrome. Neutral: Both the radial and ulnar articulating surfaces are at the same level, Positive: The styloid process of the ulna projects more distally (closer towards the carpal bones). The “trampoline sign”: This test is used to assess for overall loss of elasticity of the TFCC. The Brachioradialis muscle also gets weak in this injury. This MRI arthrogram shows a tear in the TFCC, allowing the dye (white fluid on MRI) to leak out of the joint. This often causes the muscle to tighten- contradicting your objective. [7]. If you are a new grad or a clinician that hasn’t spent much time treating or working in an orthopedic setting, acronyms like TFCC may appear intimidating or scary. Laxity in both supination and pronation potentially represents a multiplanar tear of both deep dorsal and palmar fibers of the ligamentum subcruentum. Conservative treatment is thought be ineffective for chronic TFCC lesions or tears, meaning that the tear or injury is older than 6 months [1] [5]. The Weight-bearing test must be performed by every patient with a diagnosis of a TFCC tear. It is a bit tricky to get right. Injuries to the TFCC are usually the result of a fall or forceful impact and are difficult to prevent. The doctor will test the range of motion in your wrist using minor manipulation. TFCC Compression Test: Reproduction of pain/clicking with ulnar deviation of wrist with forearm in neutral 2. The pronator gets tight, the supinator gets weak. HEAT for the ECUHeat is a vasodilator. Chinese medicine has been around a lot longer than western medicine and has validity. This test has high sensitivity of 95.2% and a specificity of 86.5%. Then bend your wrist up into extension. Though x-rays do not show soft tissues, they provide insight into the position and alignment of bony structures within joints. She has also developed a conservative management protocol for the treatment of TFCC … You can palpate the TFCC by placing a finger on the ulnar side of the wrist, on the solar surface, just distal to the ulna. This enables them to provide a lower cost way of assessing whether a TFCC dysfunction or tear may be present. Physicians may also order an X-Ray or MRI to determine extent of injury to the TFCC. The posterior interosseous nerve (or dorsal interosseous nerve) is a nerve in the forearm. http://www.ijoonline.com/text.asp?2012/46/5/493/101031, What is the TFCC? It is the continuation of the deep branch of the radial. The therapist places one hand on the distal radius and ulna to provide stabilization, with the other hand holding the client’s hand (looking like a handshake) (Rehab Solutions, 2018). a tear in the TFCC typically occurs after a fall on an outstretched hand, but can also be degenerative in origin 1,3,4. Many people find this helpful. Given the size and strength of the pronator quadratus, it tends to not be the cause of DRUJ instability. During supination, the ulna moves more to the palmar aspect of the forearm [7]. No pain to touch, No pain with stretching. The purpose of this study is to describe the use of a novel brace as a non-surgical intervention for TFCC tears. It plays a role in stabilizing the DRUJ it’s tendon sheath blends with the triangular fibrocartilage complex (TFCC) [2]. See also. Central Debridement. An injury or tear to the TFCC can cause chronic wrist pain. The distal radioulnar joint, or DRUJ, is comprised of two parts or components. The TFCC compression test: The client maintains the flexed elbow position on a flat surface. Our purpose was to describe t … Background Several different triangular fibrocartilage complex (TFCC) tear patterns have been classified through the use of wrist arthroscopy. Lee JK, Hwang JY, Lee SY, Kwon BC. In summary, supporting the ECU is extremely important when you have a TFCC injury. Physicians may also order an X-Ray or MRI to determine extent of injury to the TFCC. This classification of peripheral triangular fibrocartilage complex (TFCC) tears has been first described by Andrea Atzei 1-3. Background Several different triangular fibrocartilage complex (TFCC) tear patterns have been classified through the use of wrist arthroscopy. TFCC functions to stabilize the distal radioulnar joint, and provide shock absorption between the ulna and the carpus - Rehab U, Episode 013: Applying the Biopsychosocial Model In Practice, On The Air Podcast: Interview About Behavioral Change, Episode 012: How to Measure Value & ROI in Healthcare, Patient Relationships & Business Growth (Plus Infographic), Episode 011: Front Desk Success with Jerry Durham PT, On The Air Podcast: Interview About Behavioral Change - Rehab U Practice Solutions, Interview with The NonClinical PT: Making Impact Through Nontraditional Roles, How Understanding Behavioral Change Can Improve Outcomes, Episode 012: How to Measure Value & ROI in Healthcare - Rehab U Practice Solutions, How to Improve Patient Experience: Communication. A. There are additional treatments for ECU-only insertion and origin injuries not covered here. Then you can turn your hand with the thumb up, and bend up and down into wrist radial Please read this Therapist written blog post "How I Healed my Subluxating Extensor Carpi Ulnaris Tendon"   click here for .pdf. Salazar Enterprise, LLC. Typical tests that are done to determine a TFCC tear for a possible diagnosis is a palpation test called the Fovea Sign, which manipulates and isolates a pain location between the ulna and flexor carpi ulnaris. They all show changes with the tape or WristWidget®. Because 80% of the central TFCC —the articular disc— is avascular, it has a poor ability to heal. This is not the case for tendonitis, fractures, UT tears and much more. The TFCC compression test is performed by ulnar deviating the forearm in neutral rotation. J Hand Ther.1991; 162-168. The mechanism of injury determines what type —or class— of TFCC exists. The wrist insufflation test: a confirmatory test for detecting intercarpal ligament and triangular fibrocartilage complex tears. The test results you get from performing the Weight Bearing Test indicate whether your injury is injured. If your weight bearing tolerance is normal, then the TFCC is fine and you want to look at the ECU. I would recommend finding a rehabilitation specialist who has been trained in a variety of techniques (Certified Hand Therapist, Occupational or Physical Therapist). As far as provocative tests go, there are three tests that are the most common and accurate for assessing TFCC injuries or lesions [7]. Instruct the patient to try and push himself/herself up off the chair, while weight bearing on extended wrists. A heating pad at night around the elbow and forearm can be really helpful. Positive ulnar variance correlates with TFCC tears, though you cannot be 100% certain with an X-ray alone, since you cannot visualize the soft tissues themselves [7]. This movement allows us to manipulate our hand in a variety of positions. The opposite occurs during supination: the palmar superficial and deep dorsal fibers tighten, and the dorsal superficial and deep palmar fibers loosen [1] [2]. positive "fovea" sign tenderness in the soft spot between the ulnar styloid and flexor carpi ulnaris tendon, between the volar surface of the ulnar head and the pisiform 95% sensitivity and 87% specificity for foveal disruptions of TFCC or ulnotriquetral ligament injuries Athletes who play full-contact sports, racquet sports or who put pressure on the wrists (such as gymnasts) are at greater risk of injury. 3. There are 2 classes of TFCC injuries: Class 1, or traumatic/acute, TFCC injuries can occur during a fall on an outstretched and pronated hand, during acute rotational injuries (think hammer drill), and/or as a result of some quick, forceful distraction force. Arthroscopic Examination of TFCC Tears Three arthroscopic tests are used to check the type of TFCC lesion: 1. TFCC Tear. The Chinese MD's describe the ECU along the Small Intestine Meridian. IS IT A TFCC INJURY OR AN ECU INJURY OR BOTH? - when this test is positive (as compared to opposite wrist), then RU intability is present; - this test can be helpful in diagnosing a complete peripheral tear of the TFCC; - sensitivity (0.59), the specificity (0.96), the positive predictive value (0.91), and the negative predictive value; This has gained a lot of attention because it is helpful. The supinator and pronator muscles are often imbalanced in TFCC tears. A positive test (meaning you may have a TFCC injury) is a specific pinch pain along the ulnar (pinky) side of the joint. Arthroscopic image of a central triangular fibrocartilage complex (TFCC) tear. Instability at the DRUJ, while being indicative of a possible TFCC injury, does not automatically mean that someone has a TFCC lesion. Contrast baths are also helpful. TFCC (Triangular Fibrocartilage complex) tear Tuesday, October 16, 2018. this is a test Posted by Unknown at 4:24 PM. Wendy Medeiros, OTR, CHT (ret) has designed a weight-bearing test to objectively analyze the stability of the wrist. There are four radioulnar ligaments: During pronation and supination, two of these ligaments will tighten and two will loosen. You know that the ECU is involved if you have pain to touch at the insertion of the ECU at the back of the hand when the wrist deviates towards the ulna (ulnar deviation). TFCC provocation test: Hold the hand upright and neutral. Having the diagnosis of a TFCC tear doesn't tell you nearly enough to know what the ideal treatment might be. You know you have a TFCC tear when there is a loss of weight-bearing tolerance and an immediate increase with tape or the WristWidget. TFCC injuries are classified by the mechanism of injury and include: Palmer Class 1 (an acute tear) and Palmer Class 2 (chronic degenerative changes). A negative test (no injury) is reaching the end of the motion without pain or motion loss. You can ice the insertion at the wrist and the origin at the elbow. First start with stretching your wrist. A tear of the dorsal aspect of the TFCC has been previously reported, but it is not included in Palmer original classification. http://www.ifssh.info/2012_Bone_and_Joint_Injuries_Distal_Radioulnar_Joint_Instability.pdf, [2] LaStayoP, Lee M.
