- PURPOSE
To evaluate the clinical and radiologic outcomes of the perilunate dislocation and the lunate dislocation which were managed surgically through a dorsal approach.
MATERIALS AND METHODS
Retrospective reviews of the 13 patients who had minimum 1-year follow-up after surgical treatment through isolated dorsal approach for their perilunate dislocations or the lunate dislocations were performed. The case that dislocated lunate migrated proximally through the wrist was excluded in this series. We evaluated the DASH score in questionnaire method and Mayo wrist score to analyze the clinical outcomes. Radiologic results were investigated by measurement of the scapho-lunate angle, and fracture union was also evaluated in the case of trans-scaphoid dislocation.
RESULTS
The mean DASH Score was 16.3 points (range, 10.8~26.7 points) and the mean Mayo wrist score was 79 points (range, 65~90 points) at the final follow-up. There were 2 cases of excellent, 7 cases of good and 4 cases of fair in the Mayo wrist score. On the radiologic analysis, the mean scapho-lunate angle was 49.0degrees (range, 35~55degrees) and all cases were within the normal range. All cases of the trans-scaphoid perilunate dislocation achieved bone union.
CONCLUSION
Author's cases showed satisfactory outcomes in clinically and radiologically. Isolated dorsal approach could give anatomical reduction and appropriate internal fixation in treatment of the perilunate dislocations and the lunate dislocations except the rare case of proximal migration of the lunate through the wrist.

- PURPOSE
To evaluate the anatomic and functional outcome of retrograde intramedullary single wire fixation for metacarpal shaft fractures of the little finger.
MATERIALS AND METHODS
hirty one consecutive patients with closed metacarpal shaft fractures of the little finger who have been treated with retrograde intramedullary single wire fixation were evaluated. Fracture union and angulation were analyzed radiologically, and clinical evaluations were performed including range of motion, DASH score and complications.
RESULTS
Fracture union was achieved in all cases and callus formation was obvious at postoperative 41 days. Average angulation of fracture site was 3degrees in the coronal plane and 1.2degrees in the sagittal plane at the last follow up and no measurable metacarpal shortening was observed. Mean TAM was 253degrees and DASH score was 2.6. There were two cases of pin migration as intermediate complications.
CONCLUSION
Closed reduction with subsequent percutaneous retrograde K-wire fixation produced good radiological and functional results. We recommend this minimally invasive technique which provides adequate fixation of displaced little finger metacarpal shaft fractures with good functional results and low morbidity.
