[High tibial osteotomy for the treatment of osteoarthritis of the knee].

OBJECTIVE: To summarize clinical application of the high tibial osteatomy (HTO) with lateral closing-wedge for the treatment of pain of unicompartmental osteoarthritis of the knee. METHODS: From February 2000 to February 2004,9 patients (3 males and 6 females, ranging in age from 52 to 58 years, with an average of 56 years) with unicompartmental osteoarthritis of the knee treated by HTO with lateral closing-wedge. The proximal tibiofibular joint was exposed, the anterior part of the capsule was incised, and to remove a laterally based wedge with saw cuts and osteotomes. Stepped staples were used for the fixation of tibial osteotomies after closing the defect of osteotomy. RESULTS: The operative course was uneventful. There were no complications after operation. The postoperative follow-up period ranged from 2 to 5.5 years (mean, 3.5 years). The results were evaluated with functional assessment criterion of the osteoarthritis of the knee, among the 9 cases, excellent was in 5 cases, good in 3 cases, fair in 1 case. CONCLUSION: HTO with lateral closing-wedge is an effective operative method for the treatment of pain of unicompartmental osteoarthritis of the knee, but except for older patients over 60 years.

[Repair of scalp defect using V-Y-S rotation flap].

OBJECTIVE: To report the clinical results of scalp defect using V-Y-S rotation flap. METHODS: From March 2003 to October 2005, 5 cases scalp defect (4 male, 1 female) were reconstructed with the technique. The age ranged from 26 to 52 years (mean 32 years). The scalp defect ranged from 3 cmx3.5 cm to 4 cmx5 cm. Four cases were reconstructed with bilateral flap and one case was reconstructed with unilateral flaps. RESULTS: All patients were followed-up from 10 to 42 months (mean, 28 months). All the flaps survived completely and showed good hair growth and had satisfactory clinical results. CONCLUSION: Repair of scalp defect using V-Y-S rotation flap technique is simple with no need for a skin graft and can be performed quickly, there is minimal morbidity and the outcome is highly successful.
