Orthopaedic complications following cardiac transplantation.

Cardiac transplantation has become the treatment of choice for end stage heart disease. In 1990 2,000 transplants were performed worldwide. Orthopaedic Surgeons will be asked with increasing frequency to evaluate and treat bone and soft tissue problems with these patients. Orthopaedic service at the Mater Hospital has been involved in the follow-up treatment of orthopaedic complications in 46 transplant patients over a six year period. Thirty eight were male and eight were female. The ages were between 12 years and 65 years (mean 44.3). Nine (20%) of these patients developed thirteen orthopaedic complications: A vascular Necrosis of the hip (AVN) (4), Soft tissue infections (3), Osteoporosis (2), Stress Fractures (2), Osteomyelitis (1) and Ostomalacia (1). The mode of presentation, investigation and management of orthopaedic problems particular to these patients is described. Most patients who develop bony complications have had increased doses of steroids for episodes of rejection. This study highlights the special features of this patient population that require modification of the treatment approach such as the need to avoid the drug Erythromycin and the increased risk of AVN of the hip in patients who require high dose steroids.
