Does Extracorporeal Irradiation and Reimplantation After Acetabular Resections Result in Adequate Hip Function? A Preliminary Report

Extracorporeal Irradiation and Reimplantation with Total Hip Arthroplasty for Periacetabular Pelvic Resections: A Review of 9 Cases

We report the early results of nine patients with periacetabular malignancies treated with Enneking and Dunham type 2 resection and reconstruction using extracorporeally irradiated (ECI) tumour bone combined with total hip arthroplasty (THA). Diagnosis was chondrosarcoma in six patients, osteosarcoma in two patients, and metastatic renal cell carcinoma in one patient. All patients underwent sur...

Does fluoroscopy improve acetabular component placement in total hip arthroplasty?

BACKGROUND The success of THA largely depends on correct placement of the individual components. Traditionally, these have been placed freehand using anatomic landmarks, but studies have shown poor accuracy with this method. QUESTIONS/PURPOSES Specifically, we asked (1) does using fluoroscopy lead to more accurate and greater likelihood of cup placement with the Lewinnek safe zone than does f...

Are Portable Imaging Intraoperative Radiographs Helpful for Assessing Adequate Acetabular Cup Positioning in Total Hip Arthroplasty?

Despite advances in surgical techniques and instrumentation, current intra-operative estimations of acetabular version in total hip arthroplasty are of limited accuracy. In the present study, two experienced orthopedic surgeons compared intra-operatively measured (using portable imaging) anteversions and vertical inclinations of acetabular components with those measured using standardized radio...

Complications after Combined Hip Arthroscopy and Peri-acetabular Osteotomy

Acetabular remodelling after reduction in developmental dysplasia of the hip.

defining the femoral head and the acetabulum. The differentiation of the primitive chondroblasts leads to the formation of the femur, which is in the shape of a club. The anlagen of the ilium, ischium, and pubis develops into a disc-shaped mass. At the age of 11 weeks, the femoral head is fully formed with a spherical configuration, a short neck, and a primitive greater trochanter. 8 With conti...
