How do you test the Flexor Digitorum Superficialis and Profundus |
FDS: Flex one finger at IP joint while holding other three in extension (deactivates FDP). FDP: Hold one finger at PIP in extension and pt flexes other three |
|
|
What is a Synovial Cyst |
"Ganglion" Most commonly found on the dorsum of the wrist and contains clear mucinous fluid Close to synovial sheaths - common near origin of ECRB. Can cause compression of the median nerve by narrowing carpal tunnel |
|
|
What is Elbow Tendinitis |
"Lateral Epicondylitis" "Tennis Elbow" May be due to repetitive use of superficial extensor muscles of the forearm. Pain in LE and down posterior surface of forearm - opening door // holding a glass |
|
|
What is Mallet/Baseball finger |
Sudden severe tension on a long extensor tendon that may tear away from phalanx. Results from DIP in extreme flexion - catching a baseball Can no longer extend the DIP |
|
|
What is Dupuytren Contracture of Palmar Fascia |
Disease resulting in progressive shortening, thickening, and fibrosis of the palmar fascia Degeneration of Long. digital bands and pulls 4/5 into flexion. Frequently bilateral and requires surgical intervention |
|
|
What is Tenosynovitis |
Swelling of the tendon and synovial sheath. MOI: Puncture by rusty nail Usually confined to specific sheath/digit but if left untreated it could cause a rupture and spread to midpalmar. Little finger could spread to common sheath. How far it spreads is dependent on the variation of connecting sheaths. |
|
|
What is Quervain Tenovaginitis Stenosans |
Condition caused by excessive friction of the APL and EPB which results in fibrous thickeningg of the sheath and stenosis of the osseofibrous tunnel. Causes pain in the wrist that radiates proximally to the forearm and distally to the thumb |
|
|
What is digital tenovaginitis stenosans |
Snapping of the finger when extended passively due to tendons of FDS and FDP enlargement proximal to the tunnel. |
|
|
What is Carpel Tunnel Syndrome |
Results from any lesion that significantly reduces the size of the carpal tunnel or increase the size of structures that pass through it. Median Nerve is most affected and can cause parathesia (tingling), hypesthesia (dec sensation), Anesthesia (absence) in lateral 3 digits. Central Palm remains uneffected |
|
|
What is Carpel Tunnel Release |
Partial or complete surgical division of the flexor retinaculum to relieve the compression and resulting symptoms. Incision is made toward the medial side of the wrist and flexor retinaculum to avoid injury to the recurrent branch of the median nerve. |
|
|
What is the most common wrist fracture |
Fracture of the Distal end of the radius in people over 50 Fracture of the scaphoid is common in young adults |
|
|
What is Anterior dislocation of the lunate? |
Uncommon Fall on Dorsiflexed wrist Lunate is pulled toward the palmar surface and may compress the median nerve Low blood supply may cause avascular necrosis of the lunate |
|
|
What is Arthrodesis? |
Surgical fusion of the carpals Used in DJD of the wrist to relieve pain |
|
|
Bursitis of the Elbow |
Subcutaneous olecranon bursa Students Elbow - Repeated friction between tricpes tendon and olecranon. Pain during flexion of the forearm |
|
|
Avulsion of Medial Epicondyle |
Severe abduction of the extended elbow Can cause traction injury of the ulnar nerve |
|
|
Ulnar Collateral Ligament reconstruction |
Rupture tearing and stretching of the ulnar collateral ligament related to throwing "Tommy John Procedure" |
|
|
Dislocation of the Elbow Joint |
May occur when children fall on their hands with their elbows flexed. Sudden pulling of the upper limb tears the distal attachment of the anular ligament, where it is loosely attached to the neck of the radius. |
|
|
What is Adhesive capsulitis of the GH Joint? |
Frozen shoulder Fibrosis and scarring between the inflamed capsule of the GHJ Difficulty abducting the arm (only up to 45 degrees) |
|
|
Calcific Supraspinatus Tendinitis |
Inflam and calcification of the subacromial bursa No pain Adduction Pain in abduction from 50-130 |
|
|
Describe an Anterior Disolocation of the GHJ |
Excessive extension and lateral rotation of the humerus. Hard blow to the humerus when fully abducted. Axillary nerve may be injured |
|
|
Dislocation of acromioclavicular joint |
Direct Blow Hard fall on shouder of FOOSH Ac and coracoclavicular ligaments are torn |
|
|
Radial Nerve Injuries |
Can see wrist drop Severance of the deep branch results in inability to extend the thumb and MCP joints |
|
|
Common areas for Ulnar Nerve injuries |
Posterior to medial epicondyle Cubital tunnel Wrist Hand |
|
|
Injury to Ulnar nerve in the forearm |
Causes motor deficits in forearm and hand Wrist will flex to the lateral side by the FCR due to lack of balance from the FCU Difficulty making a fist |
