Clinical Anatomy
While treating a patient after a flexor digitorum profundus repair to the ring finger it is noted that he has a significant reduction of finger flexion force in the digits adjacent to the ring finger as well as a flexion contracture of the ring finger. What is described in his scenario?
Which is the most useful and widely known non-invasive test for evaluating the contribution of the radial and ulnar arteries to the hand?
Allens test

static progressive
What is the anatomic interconnection between flexor pollicis longus and the index finger flexor digitorum profundus called?
Linburgs Sign
In the normal hand, as each finger is flexed, the fingertips point towards what structure?
scaphoid tuberosity
Dorsal dislocation of PIP joint is from what mechanism?
What structure is injured?
How do you splint to protect this?
finger being bent backwards, volar plate, and splint in flexion 10-20 degrees
In the mature stage of handwriting, what is considered the ideal pencil grasp?
Dynamic tripod grasp
A patient presents with a prescription to fabricate an orthosis for a diagnosis of lunotriquetral ligament injury. What orthosis would be best for this patient?
Ulnar gutter orthosis
Which combination of carpal bones serves as the attachment sites of the transverse carpal ligament?
Hamate, pisaform, trapezium, and scaphoid
A patient is being evaluated after undergoing a thumb CMC arthroplasty. The patient is still wearing the postoperative plaster orthosis. During the evaluation, the patient reports symptoms of burning pain and numbness along the dorsal aspect of the hand in the area of the first web space and the index finger metacarpal. The patient also reports significant swelling in the affected hand following surgery as they complain the post operative orthosis was "too tight". What could be the source of the patients pain and numbness?
compression of the superficial sensory nerve
What is the name of the blood supply to the flexor tendons?
Vincula
A therapist has been preforming anterior capsule stretches on a patient with limited external rotation and noticed that the patient has more external rotation when in 90 degrees of shoulder abduction then then shoulder full adducted. What structure may be tight and causing this limitation?
Which flexor tendon repair orthosis utilizes a dorsal blocking component with rubber bands?
Kleinert orthosis
Non-union
Your patient is being referred for an arthrogram to confirm which of the following suspected diagnoses?
TFCC tear
What is an infection of the nailfold called?
paronychia
Educated the patient in joint protection and adaptive equipment principles.
A patient with a grade 2 collateral ligament tear of the PIP joint of the long finger is referred for an orthosis. What type of orthosis can be applied to maintain reduction?
Volar orthosis with PIP and DIP joint at 0 degrees
A patient presents with a gunshot wound to the forearm through the cubital tunnel lacerating the ulnar nerve. The clinical exam reveals that the patient has no FDP function to the small and ring finger; however, the intrinsic muscles are intact and functioning perfectly. What phenomena can explain this clinical finding?
Martin-Gruber anastomosis
A patient is seen 2 years after a crush injury to the middle finger. The patient reports hitting the dorsal PIP joint approximately 6 months ago and feeling "snap". The PIP joint rests in 60 degrees of flexion but is passively correctible. The patient is unable to initiate PIP joint extension with the joint in flexion. You also discover that with the MCP joint in neutral and the PIP joint placed in extension the patient can hold the digit in relative extension. Additionally, while placing the wrist and MCP joint in flexion and assessing active PIP joint extension the patient has a 15-20 degree lag at the PIP joint. What is the likely diagnosis?
Name the extensor tendon compartments
1. EPB/ABPL
2. ECRL/ECRB
3. EPL
4.EDC/EIP
5. EDM
6.ECU
Place palm flat against the wall with the extended arm then rotate body away from hand, median nerve glide on wall
What type of orthosis should be provided to a patient with a grade 1 skier's thumb injury?
Hand based thumb immobilization (short opponens) MCPJ at neutral to slight flexion and the CMC joint palmarly abducted 25-30 degrees
