Brief summary
Compare clinical and radiological outcome of use of single screw versus double screws fixation for subtalar arthrodesis
Detailed description
The subtalar joint consists of an anterior, posterior and medial joint facet, which allows for inversion - and eversion of the foot. Several pathologies may lead to pain originating from the subtalar joint, including primary arthritis, posttraumatic arthritis, congenital or acquired deformities, instability, tarsal coalition or inflammatory diseases Management of these pathologies variable including conservative and operative treatment once conservative treatment has failed subtalar fusion is a common surgical procedure which is a well-established and widely accepted There are many surgical techniques described for fusion , one of these techniques is fixation with screws The rate of non-union varies among authors between 0-46%, that's may due to lack of standardization of techniques should be used
Interventions
PROCEDURESubtalar Arthrodesis by Screws
Instruments: cannulated screws Steps: supine position , tournique over the thigh, using a extended lateral approach or sinus tarsi approach with joint debridement and preparation. Single-screw fixation was most often placed from posterior to anterior and double screws fixation was placed triangular pattern
