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