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
