1
Q
Boxer’s fracture
A
- MC neck is compromised due to a compressive force that travels proximately from the MC head towards the base
- typically occurs when head of fifth (and fourth) MC comes in contact with something solid with digits in full composite flexion
2
Q
Bennet’s fracture
A
- intra-articular fracture at the first CMC joint
- avulsion of the ulnar aspect of base of the first
- occurs when there is forced first CMC abduction and an axial blow along the MC shaft when the MC is slightly flexed
3
Q
Management MC fractures
A
- initial immobilization with radial or ulnar gutter orthosis or cast
- MP 70-90 deg flex, IP 0 deg ext, wrist 20 deg ext
- AROM of all uninvolved joints
- edema control
4
Q
Bunnell-Littler test
A
- determines whether stiffness is from intrinsic, extrinsic, or joint capsule tightness
- performed by flexing the IP joints as far as possible with the MP joints extended and then with the MP joints flexed
5
Q
Intrinsic tightness
A
IP joint tightness with MP ext but not MP flex
6
Q
Extrinsic tightness
A
IP joint tightness with MP flex but not MP ext
7
Q
Joint capsule tightness
A
IP joint tightness same with both MP flex and ext
8
Q
Rolando’s fracture
A
fracture of the MC base that presents with a “T” or “Y” fracture pattern that splits the articular surface of the base of the first MC
9
Q
P-1 fracture
A
proximal phalanx fracture
10
Q
P-2 fracture
A
middle phalanx fracture
11
Q
P-3 fracture
A
distal phalanx fracture
12
Q
PIP fracture dislocation
A
caused by axial compression on semi-flexed or hyperextended digit
results in a dorsal dislocation of the PIP joint
