PRIMARY PROTRUSION OF THE ACETABULUM

The Journal of Bone and Joint Surgery. British volume, 1971
1. A study of fifty-nine patients with protrusion of the acetabulum showed that they fell into three age groups: those in their teens, those aged thirty-five to fifty years, and those presenting from fifty-one years onwards. 2. The juvenile age group was investigated clinically and biochemically but no causative metabolic factor was found. 3.

Danger Zone of the Acetabulum

Journal of Orthopaedic Trauma, 1992
The danger zone of the acetabulum is defined by Marvin Tile as that part of the posterior wall and column at the mid-acetabulum lying above the ischial spine. Screws inserted in the danger zone are at risk of violating the hip joint. Unfortunately, this zone is frequently used in the fixation of posterior wall and column fractures.

PERIPROSTHETIC FRACTURES OF THE ACETABULUM

Orthopedic Clinics of North America, 1999
Periprosthetic acetabular fractures during and after total hip replacement occur infrequently. Intraoperative fractures have risen with the use of press fit cementless fixation techniques and postoperative fractures are increasing because of the long-term problems associated with osteolysis.

Avascular osteonecrosis of the acetabulum

Skeletal Radiology, 1997
To investigate the possible occurrence of osteonecrosis in the acetabulum in patients with non-traumatic necrosis of the femoral head.One hundred and seventy-nine patients with non-traumatic femoral head necrosis were assessed by MRI and radiography for the presence of acetabular necrosis.

Preoperative Assessment of the Acetabulum

Orthopedic Clinics of North America, 1993
Preoperative assessment of the acetabulum requires a good knowledge of the normal acetabular anatomy, good plain radiographs, and a knowledge of the various defect patterns that may influence the surgeon's ability to achieve secure fixation of the component at surgery. In certain situations, special radiographic techniques are advantageous.

Periosteal Augmentation of the Acetabulum

Clinical Orthopaedics and Related Research, 1998
The periosteum in children and especially infants has significant osteogenic potential. To determine the efficacy of periosteal flaps to assist in improving acetabular coverage in children with acetabular dysplasia, a series of experiments were designed using young rabbits.

Fractures of the Acetabulum

Clinical Orthopaedics and Related Research, 1986
A roentgenographic analysis of 204 acetabular fractures is presented. In addition, 64 displaced fractures (43 treated surgically) are evaluated clinically and roentgenographically (average follow-up period, 3.7 years). Most fractures can be adequately evaluated from anteroposterior and oblique roentgenograms of the pelvis.

Osteoid osteoma of the acetabulum

International Orthopaedics, 1993
Osteoid osteoma of the acetabulum can be expected to cause nonspecific symptoms of hip inflammation. In a sixteen year old girl, investigation by routine radiographs and a bone scan suggested a focus of inflammation with a nidus and sclerosis of the acetabulum and overgrowth of the head and neck of the femur.

SURGICAL APPROACHES TO THE ACETABULUM

Orthopedic Clinics of North America, 1997
This article presents a concise outline of the indications, surgical techniques, and approaches to the acetabulum: Kocher-Langenbeck approach, ilioinguinal approach, iliofemoral approach, combined approaches, extended iliofemoral approach, and the triradiate approach. No one surgical appproach is ideal for all fractures of the acetabulum.

Central fractures of the acetabulum

Injury, 1976
A series of 26 patients with central fractures of the acetabulum is presented with a follow-up of 3-13 years. Three patients had undisplaced fractures. In the remaining 23, long-term results of treatment by traction in 15 and by primary open reduction in 8 have been compared. A numerical grading system has been used for assessment.
