- PURPOSE
The purpose of this study is to evaluate the pronator quadrates muscle in patients who underwent internal fixation with a volar locking plate for unstable distal radius fractures.
MATERIALS AND METHODS
Forty patients who underwent internal fixation with a volar locking plate for unstable distal radius fracture were enrolled. We evaluated the clinical results according to the Mayo wrist score, the wrist range of motion, and the grip strength at the last follow-up. Using ultrasonography, muscle thickness of the pronator quadrates was compared between injured and uninjured arm.
RESULTS
Bone union was achieved in all cases. The mean Mayo wrist score was 82.79 points. The grip strength of the injured arm was decreased to 89.1% of the uninjured side. The decrease of pronation range of the injured wrist motions was significant (82.3degrees, p=0.004). There was significant atrophy of the pronator quadrates muscle on the injured side (injured side: 3.19 mm, uninjured side: 4.72 mm, p=0.001); and the decrement of muscle thickness in pronator quadrates showed an association with the Mayo wrist score (r=-0.35, p=0.042).
CONCLUSION
These results suggest that continuity of the muscle is maintained after use of the volar locking plating for unstable distal radius fractures with repair of pronator quadrates; however, there is atrophy of pronator quadrates muscle and limitation of pronation in the injured wrist.

- PURPOSE
We classified fractures of the greater trochanter (GT) and evaluated fracture fragment stability according to GT type.
MATERIALS AND METHODS
A total of 43 patients with an unstable intertrochanteric fracture treated between January 2007 and July 2009 with bipolar hemiarthroplasty were included in this study. GT fractures were classified as type A, B, C, or D and fixed using either cerclage wiring alone, cerclage wiring and non-absorbable suture or a greater trochanteric reattachment (GTR) plate.
RESULTS
Type A fractures were fixed using cerclage wiring with non-absorbable suture in two cases, cerclage wiring in six cases and GTR plate in seven cases. Failure occurred in three cases of type A fractures treated with cerclage wiring alone. A total of 11 type B fractures were fixed with cerclage wiring (7), cerclage wiring and non-absorbable suture (3) and GTR plate (1). There was no failure of type B fractures. Type C fractures were fixed using cerclage wiring with non-absorbable suture in one case and GTR plate in three. There was no fixation in three cases. Of 10 type D fractures, six were treated with cerclage wiring and one with GTR plate. Fixation was not performed in three patients. There was no failure in type C and D type fractures.
CONCLUSION
Fracture fragment stability differed according to fracture types. Cerclage wiring alone was insufficient to fix type A fractures, so type A fracture required a stronger fixation method.
