Purpose. Congenital insensitivity to pain is a rare autosomal recessive condition that leads to varying degrees of sensory and autonomic neuropathy. The aim of the study was to explore the common orthopaedic presentations of congenital insensitivity to pain and provide guidance on their treatment and complications. Methods. This study presents the results of fifteen patients with congenital insensitivity to pain, which were referred and treated at our supra-regional referral centre. Intradermal histamine tests and quantitative sweat tests were performed on all fifteen patients. Results. The average age of presentation was 13.2 years (range, two to 28 years). Eight patients presented with Charcot arthropathies and joint dislocations, which involved the foot/ankle (n=4), knee (n=2) or spine (n=2). Four patients presented with fractures or avascular necrosis affecting the tarsal bones and three patients presented with recurrent infections of the lower limbs. Patient education regarding appropriate shoe ware, pedal hygiene, periods of non-weight bearing, spinal bracing and close follow-up within the multi-disciplinary team was the mainstay of treatment. Patients with infection underwent cultures, aspiration, magnetic resonance imaging and treatment with antibiotics. Only one patient required joint washout for septic arthritis of the ankle. Conclusions. Congenital insensitivity to pain presents with both acute and chronic pathology affecting the weight-bearing joints. Treatment should be aimed at off-loading the pressure on these joints and preventing the development of further complications. Surgical intervention should be reserved for patients not responding to conservative treatment or those requiring debridement/washout for extensive infection
