简要总结
In this case-control study, 23 patients diagnosed as PS by diagnostic injection with ultrasound guidance were selected as the study group. 22 patients who were excluded from the diagnosis of PS and had anteroposterior (AP) direct radiographic imaging were evaluated as the control group. On the AP Pelvic graph, the femoral neck-shaft angle, the distances between predetermined bony landmarks were measured blindly without knowing the diagnosis, and the findings were compared statistically.
This study aims to evaluate whether the anatomical structure of the pelvis predisposes to the etiopathogenesis of the piriformis syndrome.
详细描述
Piriformis syndrome (PS) is a neuromuscular disorder consisting of pain and symptoms caused by compression of the sciatic nerve and other structures that pass under the piriformis muscle (PM). Due to difficulties in diagnosis, PS is confused with other pathologies such as lumbar disc pathology, lumbosacral radiculopathy, and sacroiliac dysfunction. As a result, patients are exposed to unnecessary and ineffective treatments, even surgery. The main problems in the PS diagnosis are the absence of objective physical examination findings, radiological findings, and a clear etiology. When the pathophysiology and etiology of PS are considered, there is no identifiable cause in most patients. Previous studies suggest that trauma, anatomical variations, and the trigger point in the muscle may cause PS. No study in the literature radiologically examined the pelvis or hip bone morphological features in PS to the best of our knowledge. This study aims to determine whether pelvic or hip bone morphology features pose a risk for PS in this study.

结局指标
主要结局
PSIS-Ischial Tuberosity (IT)
时间窗: The measurement was evaluated by two different investigators immediately after the pelvis anteroposterior radiography was taken.
The distance between the posterior superior iliac spine and the apex of the ischial tuberosity
IT-TM
时间窗: The measurement was evaluated by two different investigators immediately after the pelvis anteroposterior radiography was taken.
The distance between the apex of the ischial tuberosity and the greater trochanter
Femoral Neck-Shaft Angle (NSA)
时间窗: The measurement was evaluated by two different investigators immediately after the pelvis anteroposterior radiography was taken.
The NSA, also called caput collum-diaphyseal angle or inclination angle, defined as the angle between the longitudinal femoral shaft axis and femoral head-neck axis.
Sacrum-TM
时间窗: The measurement was evaluated by two different investigators immediately after the pelvis anteroposterior radiography was taken.
The distance between the sacrum and the greater trochanter
Posterior Superior Iliac Spine (PSIS)- Trochanter Major (TM)
时间窗: The measurement was evaluated by two different investigators immediately after the pelvis anteroposterior radiography was taken.
The distance between the posterior superior iliac spine and the greater trochanter
