Literature article received: this report is being filed after the subsequent review of the following literature article : zhang, c., shi, z., and mei, g.(2015) locking plate versus retrograde intramedullary nail fixation for tibiotalocalcaneal arthrodesis: a retrospective analysis.Indian journal of orthopaedics 2015 mar-apr; 49(2): 227¿232.(b)(4).Purpose of study: we retrospectively reviewed the records of 71 patients who underwent tibiotalocalcaneal arthrodesis (ttca) by retrograde intramedullary nail fixation (rinf) or locking plate fixation (lpf) in our hospital between (b)(6) 2007 and (b)(6) 2010.All patients had a diagnosis of tibiotalar and subtalar joints lesions by ankle and foot weight bearing x-ray, computed tomography, and/or magnetic resonance imaging.The eligibility criteria included severe tibiotalar joint lesions combined with subtalar joint lesions and failure to respond to a fair trial of conservative therapy.Exclusion criteria included active infectious disease, diabetes mellitus, severe congenital bone defects or revision surgery.Fifty four patients were included in the final analysis.Patient demographic: ttca surgery with rinf (n = 32, 18 males [56.3%] and 14 females [43.7%]) or lpf (n = 22, 12 males [54.6%] and 10 females [45.4%]).Mean age at surgery for rinf was 48 ± 11 and lpf was 51 ± 12 years.Type of surgery: 32 patients had retrograde intramedullary nail fixation (rinf) and 22 had locking plate fixation (lpf).Implants used: the implant used in all lpf cases was proximal humeral lpf philos, synthes.Complications reported: bone nonunion (1), revision surgery (1),wound skin flap necrosis (2) requiring debridement and re-suture, superficial wound infections (1) requiring intravenous antibiotics.This is report 1 of 1 for (b)(4).This report is for an unknown proximal humeral lpf philos, synthes.
