Intertrochanteric Hip Fracture

Basics Description Fractures of the proximal femur located between the greater and lesser trochanters and external to the capsule of the hip joint The greater and lesser trochanters may be avulsed as separate fragments. Many classification systems have been developed that are unreliable in identifying fracture types, but in general, they are classified as […]

Hip Replacement

Basics Description Many forms of arthritis lead to destruction of the articular cartilage of the hip joint, resulting in pain and loss of function. End-stage arthritis can be treated with surgical replacement of the joint. Elderly patients may have a greater risk of cardiac complications and more associated medical problems than younger patients. Patients […]

Hip Arthritis

Basics Description Hip arthritis is caused by loss of the articular cartilage of the acetabulum and proximal femur. As the cartilage is lost, the subchondral bone of the proximal femur and the acetabulum rub, causing pain with ambulation, loss of motion, and disability. General Prevention Low-impact exercise (swimming, biking, walking) Activity modification Weight loss […]

Femoral Neck Fracture

Basics Description Femoral neck fracture is the most common cause of a broken hip. The femoral neck is the intracapsular portion of the proximal femur between the femoral head and the lesser and greater trochanters. Femoral neck fractures are most common in elderly patients, although younger patients involved in high-energy trauma also are affected. […]

Deep Venous Thrombosis

Basics Description DVT is a blood clot in the deep venous plexus of the legs. Venous thrombus may embolize and result in fatal PE. Classification: DVTs are classified by location using ultrasound. Thrombi below the popliteal fossa usually do not embolize. 50% of thrombi at or above the popliteal fossa will embolize. General Prevention […]

A Patient’s Guide to Trochanteric Bursitis Surgery

Introduction

The bump of bone on the outside of the hip bone is called the greater trochanter. A fluid-filled sac, called a bursa, lies next to the greater trochanter. When the bursa in this area becomes thickened and inflamed, surgery may be needed to remove the bursa and to reduce tension on the tendon that […]
