Treatment of Bunionette Deformity with Distal Chevron Osteotomy / 대한정형외과학회잡지

PURPOSE: To evaluate a symptomatic bunionette managed by a distal chevron osteotomy. MATERIALS AND METHODS: From 1997, among eighty-three patients who had been treated for a bunionette deformity with a distal chevron osteotomy, 17 patients, who had no other associated diseases, were reviewed retrospectively. The VAS pain score and AOFAS score, the patient satisfaction level, shoe selectability and disappearance of the callus on the foot were examined. The 5th metatarso-phalangeal angle and 4th and 5th intermetatarsal angle were measured using AP plain radiography. The bunionette was classified as types 1, 2, and 3 and the treatment results were analyzed. RESULTS: 8 male and 9 female patients were enrolled in this study. The mean age of the patients was 33.6 years (21-49 years). The mean follow-up period was 37.6 months (20-62 months). The pain VAS scores were 7.9 preoperatively and 1.2 postoperatively. The last follow-up AOFAS score was 94.7, and all patients were ranked at the very satisfied or satisfied level. All patients had also good shoe selectability and the callus on the lateral sole had disappeared. The preoperative 4th and 5th intermetatarsal angle (mean 10.2 degrees) and the 5th metatarso-phalangeal angle (mean 21.4 degrees) improved to 2.7 degrees and 7.2 degrees after surgery, respectively. There was a type 1, 2 and 3 deformity in 2 (12%), 1 (6%) and 14 patients (82%), respectively. The results among the types were satisfactory. CONCLUSION: A distal chevron osteotomy for the treatment of a symptomatic bunionette is safe, easy and can reduce the signs and symptoms. Regardless of the types of deformity, a distal chevron osteotomy can obtain satisfactory results.

External Fixator and External Fixator Supplemented with K-wire in the Treatment of Distal Radius Fractures

PURPOSE: To evaluate the differences of the outcome between external fixator and external fixator supplemented with K-wire in the treatment of distal radius fractures. MATERIALS AND METHODS: Twenty-one cases which underwent external fixation (external fixation group) and 28 cases, external fixation supplemented with K-wire (external fixation with K-wire group), were analyzed. Radial length, radial inclination and volar tilt were compared in preoperative, immediate postoperative radiographs, and radiographs after removal of external fixator between two groups. And functional outcome including flexion, extension, pronation and supination of wrist were compared between two groups and wrist pain, as well. RESULT: Radial length and radial inclination in the postoperative radiographs and radiographs after removal of external fixator showed no difference between two groups, but volar tilt of external fixation group measured 2.1+/-4.2 degrees, 1.3+/-3.8 degrees and external fixation with K-wire group, 8.8+/-2.3 degrees, 8.5+/-2.4 degrees respectively, so that external fixation with K-wire group showed better reduction and maintenance. Wrist flexion and extension about postoperative 6 months measured 25.6+/-8.2 degrees, 25.1+/-10.2 degrees, respectively, in external fixation group and 42.5+/-15.2 degrees, 33.6+/-9.5 degrees in external fixation with K-wire group, so that external fixation with K-wire group showed better functional results. CONCLUSION: In the treatment of distal radius fractures, to obtain better reduction and function result, external fixations supplemented with K-wire need to be taken into consideration.
