The Results of Distal Chevron Osteotomy with Lateral Soft Tissue Release for Hallux Valgus Deformity / 대한족부족관절학회지

PURPOSE: To evaluate the results and effectiveness of distal chevron osteotomy combined with lateral soft tissue release for the correction of hallux valgus deformity. MATERIALS AND METHODS: 31 patients who underwent distal chevron osteotomy with lateral soft tissue release between July 2002 and June 2003, were analyzed in terms of hallux valgus angle, intermetatarsal angle, subluxation of sesamoid, AOFAS score and the occurrence of avascular necrosis of the first metatarsal head. RESULTS: The mean amount of the correction of hallux valgus angle was 26.3 degrees . The mean amount of the correction of intermetatarsal angle was 6.6 degrees. The mean amount of the correction of sesamoid subluxation was 1.2 points. The mean improvement of AOFAS score was 25.8 points. Avascular necrosis of the first metatarsal head was not found in any cases. CONCLUSION: For correction of hallux valgus deformity, distal chevron osteotomy with lateral soft tissue release showed improvement of hallux valgus angle, sesamoid subluxation and AOFAS score with no evidence of avascular necrosis of the first metatarsal head.

Prognostic Factors of Hemiarthroplasty for the Proximal Humeral Fractures / 대한정형외과학회잡지

PURPOSE: The purpose of the study was to evaluate the results and analyze various prognostic factors of hemiarthroplasty for proximal humeral fractures. MATERIALS AND METHODS: Thirty-one cases, who underwent hemiarthroplasties for proximal humeral fractures, were evaluated with ASES score at a mean follow-up of 45 months (1-8 years). Global Total Shoulder (Depuy.) (TS Gr) for 21 cases, and Global FX (Depuy.) (FX Gr) for 10 cases were used. Twentysix cases were acute fractures within one month after injury. There were two cases with delayed union and three cases with nonunion. Prognostic values of age, delay of surgery, fracture type, position of the greater tuberosity and design of implant were assessed. RESULTS: The most important prognostic factor was the design of implant. Mean score of FX Gr was significantly higher than that of TS Gr (84.4 and 77.6 respectively, p=0.036). Age, fracture type, delay of surgery and position of the greater tuberosity did not show any prognostic value. CONCLUSION: The clinical results of Hemiarthroplasty specially designed for the proximal humeral fractures has better than that of preexisting implant. Design of the implant was considered to be the most important prognostic factor of hemiarthroplasty for the proximal humeral fractures.
