Bilateral THA in the same sitting for avascular necrosis of the head of the femur in sickle cell patient: our African experience.

Sickle cell anemia is protective against the malaria protozoan. The heterozygous form of the disease is not fatal, and may cause musculoskeletal disorders when sickling occurs, and small vessels are occluded. When the head of the femur is involved, this may result in hip arthritis, often bilateral, at a young age. This article describes three patients in whom bilateral total hip arthroplasty (THA) was performed in the context of a humanitarian mission in Togo, Africa.

Periprosthetic joint infection from Mycobacterium Tuberculosis in Togo, Africa.

Mycobacterium Tuberculosis infections are moderately frequent in developing countries. Because of migratory flows, these diseases will always have an increasing prevalence even in those countries that do not usually present these types of cases. Extra-pulmonary tuberculosis often affects the musculoskeletal system. The sites most involved are the spine (Pott's disease) and the large joints, especially hips and knees. We describe a patient with tuberculosis of the hip, who underwent total hip arthroplasty.

One-stage Bilateral Total Hip Arthroplasty in patient with sickle cell disease and previous Girdlestone procedure on the right side: First presentation in Togo.

80% of Sickle Cell Disease cases are estimated to be in Sub-Saharan Africa. It can lead to various acute and chronic complications and osteonecrosis of the femoral head is one of these. Girdlestone procedure is an option to treat osteonecrosis in patients who could not afford arthroplasty. We report here the first case of bilateral total hip arthroplasty in a patient with a previous Girdlestone procedure on the right side and an osteonecrosis of the femoral hip on the left side.

Total hip arthroplasty for osteonecrosis of the femoral head in sickle cell disease: a case series from our African experience.

Sickle cell disease causes osteonecrosis (20% to 50% of patients) and collapse of the femoral head that result in secondary osteoarthritis. Total hip arthroplasty (THA) is a valid alternative for these patients. We define the difficulties that can be encountered when undertaking THA in sickle cell disease patients and give advice on how to deal with these technically demanding procedures. We undertook total hip arthroplasty procedures on 12 patients (4 females and 8 males) with osteonecrosis of the femoral head. Two bilateral prostheses were performed. We had only one type of stem, only one type of acetabular cup and only 28 mm cobalt chrome heads. The procedures were performed through either an anterior or a direct lateral approach. The average size of the Cup was 46 (Versafit, Medacta), the average size of the femoral stem was 0 (Amistem, Medacta), the most used size of the modular head was a S. Standard stem that was used in nine patients, while three patients received a lateralizing stem. Three patients had periprosthetic fracture, treated by cerclage. Total hip replacement is an excellent alternative for patients with osteonecrosis from sickle cell disease. The preparation of the acetabulum and the femur is difficult and requires attention, time and appropriate equipment.

Static-dynamic intramedullary nailing (SDIN) in diaphyseal and metaphyseal lower limb fractures.

The authors report their experience with the Grosse-Kempf nail in treatment of diaphyseal and metaphyseal fractures of the femur and tibia. The biological and biomechanical preconditions of the method as well as several details of the surgical technique are discussed, and the results of 70 procedures performed from 1986 to 1989 are evaluated. The outcomes are quite positive and confirm other reports in the literature.
