| Abstract | PURPOSES: To review the outcome of Z-plasty of the flexor hallucis longus (FHL) tendon at the tarsal tunnel for checkrein deformity in 8 patients. METHODS: Records of 6 males and 2 females aged 14 to 67 (mean, 39.5) years who underwent Z-plasty (lengthening) of the FHL tendon at the tarsal tunnel for checkrein deformity in the first and second toes by a single surgeon were reviewed. All patients had undergone 3 months of conservative treatment. The mean time from injury to surgical treatment was 8.4 (range, 5-12) months. All patients had associated injuries including distal tibiofibular fracture (n=6), distal fibular fracture (n=1), and crush injury aroundthe ankle (n=1); they were treated with intramedullary nailing (n=6), long leg splinting (n=1), and short leg splinting (n=1). RESULTS: After a mean follow-up of 3.4 (range, 1-7) years, the FHL tendon was lengthened by a mean of 1.7 (range, 1.6-1.8) cm, and the mean American Orthopedic Foot and Ankle Society hallux score increased from 59 (range, 52-67) to 89 (range, 80-90). No patient had recurrence, nerve injury, or tarsal tunnel syndrome, although one patient had sensory disturbance of the posterior tibial nerve in the forefoot, which resolved spontaneously at week 2. CONCLUSION: Z-plasty of the FHL tendon at the tarsal tunnel is a viable option for correction of checkrein deformity.
