Normal: ≤68° in men, ≤50° in women; Borderline: 69° to 82° in men, 51° to 56° in women; Pathological: ≥83° in men and ≥57° in women; Femoral head-neck offset Measured in cross-lateral view. Offset of the femoral head with regard to most prominent aspect of the femora neck >10 mm Offset percentage
The neck is flattened from before backward, contracted in the middle, and broader laterally than medially. The vertical diameter of the lateral half is increased by the obliquity of the lower edge, which slopes downward to join the body at the level of the lesser trochanter, so that it measures one-third more than the antero-posterior diameter.
Protrusio acetabuli is an uncommon defect of the acetabulum, the socket that receives the femoral head to make the hip joint. The hip bone of the pelvic bone/girdle is composed of three bones, the ilium, the ischium and the pubis. In protrusio deformity, there is medial displacement of the femoral head in that the medial aspect of the femoral ...
Moreover, pregnancy is a well-recognized risk factor for femoral neck fatigue fracture. While fibular and metatarsal fractures have a low risk of complications, other sites including the femoral neck, midanterior tibia, navicular, talar, and other intraarticular fractures are prone to complications such as delayed union, nonunion, and displacement.
The lesser trochanter is a conical posteromedial projection of the shaft of the femur, projecting from the posteroinferior aspect of its junction with the femoral neck. [1] The summit and anterior surface of the lesser trochanter are rough, whereas its posterior surface is smooth. [1] From its apex three well-marked borders extend: [2]
Other techniques, such as metal-on-metal resurfacing, may not be suitable in all cases of avascular necrosis; its suitability depends on how much damage has occurred to the femoral head. [23] Bisphosphonates , which reduce the rate of bone breakdown, may prevent collapse (specifically of the hip) due to AVN.
Greater trochanteric pain syndrome (GTPS), a form of bursitis, is inflammation of the trochanteric bursa, a part of the hip.. This bursa is at the top, outer side of the femur, between the insertion of the gluteus medius and gluteus minimus muscles into the greater trochanter of the femur and the femoral shaft.
The vast majority of clinically significant bone lesions are detectable by age 10 years, with few new and almost no clinically significant bone lesions appearing after age 15 years. [8] Total body scintigraphy is useful to identify and determine the extent of bone lesions, and should be performed in all patients with suspected fibrous dysplasia ...
