Tibial intramedullary nail distal interlocking screw placement: comparison of the free-hand versus distally-based targeting device techniques.

摘要: Abstract Intramedullary nailing is the standard treatment for closed and some open unstable diaphyseal tibia fractures. Fluoroscopy, while essential proper nail placement can subject surgical team patient to substantial radiation. A new targeting system distal interlocking was developed by Orthofix® limit fluoroscopy. This prospective clinical study compares versus a free-hand technique tibial interlocking. Fifty eight consecutive patients with sixty fractures amenable fixation were randomly assigned into two equal groups: Group 1: distally based device 2: technique. In all cases stabilization achieved reamed statically locked nail. Recorded data included accuracy of screw placement, duration surgery prior during interlocking, fluoroscopy time Both groups revealed comparable fracture patterns. technical aspects performed without complications. There no statistically significant difference between in mean (62.02 vs. 61.01 min, P=0.92) (17.06 19.08 P=0.55), or total (81 85 min), respectively. Neither there (69 81 s, p=0.22) nor (84 117 s). however, Orthofix regards (15 36 P=0.01, respectively). demonstrates that significantly decrease necessary complete
