Randomized Controlled Study Comparing Zimmer Natural Nail System Cephalomedullary Asia Nail with Anterior Support Screw (ASS) versus Conventional Technique
- Conditions
- Fracture type is classified as 3-partB or 4-part fracture in 3D-CT classification (Nakano), and combination with a subtype P in lateral classification (Ikuta) at preoperative CT assessment.
- Registration Number
- JPRN-UMIN000026639
- Lead Sponsor
- Zimmer Biomet G.K.
- Brief Summary
This study showed that ASS technique can restrain the displacement of the proximal bone fragment to the intramedullary type and excessive sliding of lag screw which leads to postoperative complications such as re-dislodgement of bone fragment and cut-out, in the treatment of femoral trochanteric fractures without appropriate posterior bony support.
