The effects of shoulder and hip widths on the acetabular angle in hip arthroplasty performed in the lateral decubitus position. Trochanter/shoulder ratio effect on postop inclination

Objectives This study aimed to determine the effects of soft tissue and bone widths patient's hip shoulder region on position postoperative acetabular inclination angles in lateral decubitus during replacement procedures. Materials Methods Seventy-three patients with primary coxarthrosis who underwent arthroplasty by a single experienced surgeon using water gauge assisted inclinometer were retrospectively studied. Soft shoulder, ASIS (Anterior superior iliac spine), trochanter levels measured from preoperative radiographs shoulder/hip (ASIS-trochanter) ratios calculated made statistical comparisons angle. Results Postoperative angle had strong negative correlation trochanter/shoulder ratio, moderate ASIS/shoulder weak ratios. When are grouped value is 43.04 (38-47) degrees group ratio < 0.85, 38.67 (33-45) 0.85-1, mean > 1 was found be 35.60 (30-38) degrees. (p 0.001) As for values, values ≤ 40 0.99 0.94, respectively, while these 0.83 0.79, respectively. 0.001). Conclusions regions may affect surgical Knowing relationship between distance can influence expected clinical outcome after arthroplasty. Therefore, surgeons should consider when planning surgery.
