Objective To investigate the clinical efficiency of repairing ankle and calf wounds by antegrade or retrograde perforating flap of posterior tibial artery. Methods 13 cases with skin defects of ankle and calf wounds were reviewd. The defects were repaired using antegrade or retrograde perforating flap of posterior tibial artery from January 2011 to February 2013, 8 males and 5 females; aged 19 to 65 years old. Wounds were located in the ankle and calf, area which the tibial artery support contu-sioned slightly;defects were associated with exposed bone or tendon, exposed blood vessels. Of the 13 cases, 5 cases have multiple ankle fracture with blood circulation disorders, internal and external fracture fixation were performed emergency with blood ves-sels and nerves exposed, at the same time emergency line wound repair by posterior tibial artery perforating flap. The other 8 cases have no blood vessels and nerves exposure, and accepted vacuum sealing drainage emergency external fixation and flap surgery. Seven cases accepted V-Y antegrade perforating flap of posterior tibial artery, 6 cases using retrograde tibial artery perforator flap. Whose defects were ranged from 1.5 cm×2.0 cm to 9.0 cm×5.0 cm. Antegrade or retrograde perforating flap of posterior tibial ar-tery with 1.5 cm×3.0 cm to 14.0 cm×7.0 cm was used to repair ankle or lower leg medial defect. Antegrade flap donor site sutured directly, but retrograde flap donor site take full thickness skin graft repair from abdomen. Results Circulations of the all 13 cases were stable, with wound healing well after 2 weeks. The patients were followed up for 6 months to 24 months, average of 13 months. All flap graft survived, pedicle no bloated andcat eardeformity. Flaps were soft, no bloated appearance;color was con-sistent with normal skin. Fracture line in the 5 patients was disappeared. Bone healing time was 3.0 to 4.0 months. At the direct su-ture skin donor sites, postoperative scar was small;skin graft donor sites had no obvious scar. Postoperative ankle dorsiflexion 10° to 25°, plantar flexion 15° to 45°. Patients were extremely satisfied with the results of repair. Conclusion Using antegrade or ret-rograde posterior tibial artery perforator flap without sacrificing the main vessel, it is a simple and effective method to repair the medial malleolus and calf wounds.

BACKGROUND: It is easy and feasible to treat anterior urethral stricture using internal urethrotomy, however, its drawback is high recurrence in the long-term follow-up. OBJECTIVE: To evaluate the effect of submucosal injected verapamil on prevention of anterior urethral stricture recurrence after internal urethrotomy. METHODS: Totally 60 consecutive males with anterior urethral stricture underwent internal urethrotomy with or without urethral submucosal injection of verapamil, in the Department of Urology, First Affiliated Hospital of Fujian Medical University, from December 2006 to April 2008, were selected. All cases were followed up at least 24 months.RESULTS AND CONCLUSION: All cases were followed up for 24-39 months, with an average of 28.5 months. Urethral stricture recurred in two cases in the verapamil-treated group but 8 cases in the untreated group. This difference in stricture recurrence between the two groups was statistically significant (P < 0.05). The results demonstrated that submucosal injection of verapamil at the stricture site significantly reduces the stricture recurrence rate after internal urethrotomy. Further studies involving larger number of cases and longer follow-up are warranted to confirm the efficacy and safety of this therapy.

OBJECTIVETo summarize the therapeutic effect of free perforator hypothenar flap for thumb pulp defect.

METHODSFrom Jun. 2012 to Mar. 2013,8 cases with thumb pulp defect accompanied with exposure of phalanges ans tendons were treated by free ipsilateral perforator hypothenar flap. The flaps were 1.4 cm x 2.0 cm-1.8 cm x 2.2 cm in size. Ulnar finger artery in the flap was anastomosed with thumb artery. The accompanied veins and superficial veins were respectively anastomosed with thumb dorsal veins. Nerve branches in flaps were sutured with unilateral finger nerve to reconstruct flap feeling with 9-0 thread. Wounds in the hypothenar donor site were sutured directly.

RESULTSAll the flaps survived completely with primary healing both in donor and recipient area. 8 cases (8 fingers) were followed up for 6-13 months (average 9 months). The flaps appearance, texture were good. The two-point discrimination distance on flap was 7-10 mm. The active and passive movement of thumb joints was normal. There was no complain about the feeling at the donor site. Linear scar was left on the donor site. Patients hand grip strength was not decreased.

CONCLUSIONSThe free perforator hypothenar flap which has constant vascular anatomy is a new method for thumb soft tissue defect with less morbidity to donor site. The operative procedures are relatively simple.
