Living with Upington disease

A rare bone condition with hip changes similar to Perthes disease, joint pain, and bone growths.

Understanding Upington disease

Upington disease is a rare bone condition with hip bone changes similar to Perthes disease, hip and knee pain, and benign cartilage growths in the bone.

The ball of the thighbone can close early and look flattened, and the neck of the thighbone is wide. People may also have cartilage growths (enchondromata and ecchondromata). GARD says there have been no further descriptions in the medical literature since 1971.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Hip joint pain
  • Joint pain in the hips and knees
  • Wide neck of the thighbone
  • Flat end of the thighbone
  • Early closure of growth plates
  • Cartilage growths in bone (enchondroma)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

Quick facts

InheritanceAutosomal Dominant

GARD says changes in genes (variants) cause this condition and that it is autosomal dominant, so one changed copy of a gene can be enough. It doesn't name a specific gene.

Genetic

Also known as: hip dysplasia with enchondromata and ecchondroma syndrome; hip dysplasia-enchondromata-ecchondroma syndrome; perthes-like hip disease, enchondromata, and ecchondromata
