A comparison between proximal femoral nail antirotation (PFNA) and inter Tan nail for the surgical treatment of unstable intertrochanteric fracture: A case series

摘要

The incidence of intertrochanteric fractures is rapidly increasing. An unstable intertrochanteric fracture lacks continuity of the bone cortex on the opposing surfaces of the proximal and distal fragments. This cortical deficit is due to either comminution on the medial aspect of the neck (calcar region) or a large and sepa- rate posterior trochanteric fragment. Sometimes a combination of the two is present. 1 The instability is generally unrecognized, and anatomical reduction does not restore stability. The unstable inter- trochanteric fracture is not rare. 2 Inter Tan nail and proximal femoral nail antirotation (PFNA) nail are the common new genera- tion of intramedullary fixations for the treatment of intertrochan- teric fractures. We study the clinical effects of two nails in unstable intertrochanteric fracture, and analyze the key points of related design, manufacture and application.
