Upington disease

Upington disease, also known as Upington bone disease or perthes-like hip dysplasia, is an extremely rare skeletal disorder first described in a large Afrikaner family from Upington, South Africa. The condition primarily affects the skeletal system, particularly the hip joints, and is characterized by enchondroma-like lesions of the long bones and a bilateral hip disorder resembling Perthes disease (avascular necrosis of the femoral head). Affected individuals typically develop progressive hip joint abnormalities during childhood, which can lead to pain, limited range of motion, and difficulty walking. The disease manifests with bilateral flattening and fragmentation of the femoral heads, similar to Legg-Calvé-Perthes disease, but distinguished by its hereditary pattern and the presence of additional skeletal abnormalities including enchondroma-like cartilaginous lesions in the metaphyses of tubular bones. Radiographic findings may also include irregularities of the epiphyses and metaphyses of other long bones beyond the hips. The condition can lead to early-onset degenerative arthritis of the hip joints. There is no specific curative treatment for Upington disease. Management is primarily supportive and symptomatic, focusing on orthopedic interventions to preserve hip joint function, pain management, and physical therapy. In severe cases, surgical procedures including hip replacement may be necessary. Due to the extreme rarity of this condition, knowledge is largely based on the original family described in the medical literature, and further research is needed to fully characterize the natural history and optimal management strategies.
