[Percutaneous pinning for the treatment of proximal humerus fractures].
OBJECTIVE
The indication, surgical techniques and results had been discussed through clinical analysis of percutaneous pinning for the treatment of proximal humerus fractures.


METHODS
Forty-nine patients with 49 shoulders treated with percutaneous pinning had been reviewed with a mean follow-up period of 16.9 months. All were acute fractures, with a mean age of 40.4 years. There were 39 2-part surgical neck fractures, 6 impacted 2-part greater tuberosity fractures and 4 valgus-impaction 4-part fractures. SST (Simple Shoulder Test) questionnaire, ASES (American Shoulder & Elbow Surgeon) score, Constant-Murley score and UCLA score had been adopted for final evaluation at the latest follow-up.


RESULTS
The mean ASES score was 91.4, the mean VAS score was 1.7, the mean forward flexion was 146.7 degrees, external rotation 39.6 degrees, internal rotation at T(8)-T(9) level; the mean Constant-Murley score was 88.2; the mean UCLA score was 31.2; the mean number of questions for "yes" in SST questionnaire was 10.1. All fractures healed with a mean period of 8.8 weeks. No patient had been found for any evidence of humeral head necrosis at the latest follow-up The total satisfaction rate for pain relieve was 95.9% (47/49), and for functional recovery was 91.8% (45/49).


CONCLUSIONS
Most 2-part surgical neck fractures, impacted 2-part greater tuberosity fractures and 4-part valgus-impaction fractures are good indications for percutaneous pinning. With appropriate and intense rehabilitation, satisfactory results can be expected in percutaneous pinning for the treatment of certain types of proximal humerus fractures.
