Comparison of patient positions without traction table for proximal femoral nailing: Supine, semilithotomy and lateral decubitus positions.

Background: Femur intertrochanteric fractures are performed commonly in a supine position with a traction table. There is a challenge in obtaining traction tables, especially in low- and middle-income countries. However, there is still a debate on which position should be preferred if the traction table cannot be obtained.

Methods: A total of 123 patients who were treated for femur intertrochanteric fracture (AO/OTA A1 or A2) using cephalomedullary nail (CN) were retrospectively analyzed. All three positions without traction table (supine:25 patients, semilithotomy:36 patients and lateral decubitus:62 patients) were compared according to preparation time, surgical time, Tip-Apex distance (TAD), zones of lag screw placement, collodiaphyseal angle (CDA), CDA difference (∆ CDA), postoperative posterior sag, medial cortical support and Baumgardner reduction quality criteria.

Results: The preparation time was longer in the semilithotomy group, and surgery time was longer in the supine position group. There was no difference according to total time, surgical time, TAD, CDA difference (∆ CDA), postoperative posterior sag, medial cortical support and Baumgardner reduction quality criteria. Target lag screw placement is superior in supine and semilithotomy group than lateral decubitus.

Conclusion: This study concluded that there was a difference in preparation time, surgery time and optimal lag screw placement in the lateral plane between groups. The surgeon may prefer all three methods according to patient benefit and surgeon familiarity.
