Arthritic Hip, Posterior View

Description

Posteriorly oriented anatomy centers on the proximal femur, with the femoral head and neck projecting superomedially toward the acetabulum and the greater trochanter forming a broad lateral prominence. Surface change along the femoral head suggests cartilage loss with exposed subchondral bone, and the head-neck junction appears less smoothly contoured where osteophytes and remodeling typically accumulate. Inferior to the neck, the intertrochanteric region transitions into the proximal shaft, and irregularity along the posterior aspect of the greater trochanter is consistent with traction-related enthesopathic change at the insertions of the short external rotators. Degenerative change at the coxal (hip) joint is often most clinically legible when you consider how posterior joint loading and capsular tightness concentrate pain and stiffness in extension and internal rotation, findings that distinguish advanced osteoarthritis from isolated trochanteric pain syndromes. For surgeons, posterior bony irregularity around the trochanter and head-neck offset relates directly to the posterior approach for total hip arthroplasty, where the piriformis and obturator internus tendon complex is released near the trochanter and the sciatic nerve runs just posterior and lateral to the ischial tuberosity. Femoral head surface collapse and mottled exposure can also track with osteonecrosis (avascular necrosis), a key differential when symptoms progress faster than radiographic joint-space loss. Orthopedic teaching files and MSK anatomy courses can use this posterior male hip view to correlate gross pathology with exam findings, radiographs, and preoperative planning for arthroplasty or osteotomy. It also fits well in medical publisher chapters on hip osteoarthritis, femoroacetabular impingement morphology at the head-neck junction, and posterior surgical anatomy of the pelvis and proximal femur.
