Purpose: Authors analyzed and compared the treatment result of distal chevron osteotomy between with and without adductor tenotomy. Materials and Methods: 36 patients (60 feet) with a minimum follow-up of one year were involved in this retrospective study. The chevron osteotomy without adductor tenotomy was performed for 20 patients (30 feet) and chevron osteotomy with adductor tenotomy was done for 16 patients (30 feet). The first metatarsophalangeal (MTP) angle and angle between first and second metatarsal longitudinal axis (IM) was measured. The difference of these angles were measured pre-and postoperatively and compared using Student's T-test. Results: In the group of chevron osteotomy with adductor tenotomy, the mean first MTP angle corrected $29^{\circ}$ pre-operatively to $9^{\circ}$ and the mean first IM angle corrected $16^{\circ}$ pre-operatively to $12^{\circ}$. In the group of chevron osteotomy without adductor tenotomy the mean first MTP angle corrected $31^{\circ}$ pre-operatively to $11^{\circ}$ (P>0.05) and the mean first IM angle corrected $13^{\circ}$ pre-operatively to $11^{\circ}$ (P>0.05). Deep peroneal neuroma were found in 3 cases of chevron osteotomy with adductor tenotomy. Conclusions: Adductor tenotomy should be performed in selected patient with chevron osteotomy to prevent deep peroneal neuroma.

Objective : Cerebral palsy may induce harmful spastic hip adduction. We report the result of microsurgical selective obturator neurotomy, performed on 12 spastic hip adductions of 6 patients, followed clinically for at least 26 months postoperatively. Methods : Microsurgical selective obturator neurotomies, involving microsurgical resection of the anterior obturator nerve branches were performed on 6 patients from January 2000 through June 2003. All patients presented with the inability to sit and 2 patients complained of persistent, intractable pain. We used intraoperative bipolar stimulation to identify selected motor branches. Results : The procedure was performed bilaterally in all patients. In the 3 patients in whom contractures were present, microsurgical selective obturator neurotomies were accompanied by an additional tenotomy of the adductor muscles. Selective tibial neurotomy was performed on three of six patients who originally presented with a spastic ankle. Postoperatively, all spastic hip adductions were corrected more than 60 degrees in passive abduction-adduction amplitude. However, one patient who did not receive active postoperative physiotherapy demonstrated a decreased passive abduction-adduction amplitude upon follow-up. There were no surgical complications. Conclusion : We think microsurgical selective obturator neurotomy may be an effective procedure in the treatment of localized, harmful spastic hip adduction after failure of well conducted conservative treatment. As muscular contractions are often associated with spasticity of the hip adductors, an adjunctive tenotomy may be an option. Comprehensive postoperative physiotherapy is essential to improve long-term results.

A postoperative hallux varus deformity is a dreaded complication of hallux valgus surgery. Several surgical options have been introduced to overcome this problem. This paper reports an uncommon case of a 68-year-old female patient who presented with a postoperative hallux varus deformity combined with a rupture of the flexor hallucis longus (FHL) tendon. She was treated successfully by a minimally invasive correctional osteotomy with open tenorrhaphy. With experience in treating this complicated case, it was noted that FHL could be transected during the trans-articular adductor tenotomy. Hence, extra caution is needed when the degree of hallux valgus deformity is excessive. To the best of the author's knowledge, correctional valgization osteotomy for a postoperative hallux varus deformity in a minimally invasive manner has not been reported. This case report is expected to benefit surgeons and their patients with severe hallux valgus deformity.
