Heterotrophic Ossification after Aggressive Rehabilitation in Patients with Trauma: A Case Report

ABSTRACT

Heterotrophic ossification (HO) is a reactive disease presenting the formation of mature lamellar bone in soft tissues. It is known to occur following surgery, soft tissue injury, or central nervous system anomalies. However, a definite cause has not yet been clearly addressed. During the process of approach, reduction, and fixation while conducting surgeries, partial injury of soft tissue is inevitable. Additionally, secondary injuries may be caused during the active and passive range of motion exercises that should be done for the recovery of joint motion after surgery. The authors experienced cases of HO that may occur during surgery and rehabilitation after surgery. The authors recognized that special care is required for patients complaining of severe pain during the early stage of rehabilitation immediately after surgery. This study aimed to reaffirm the principles of fracture treatment by reviewing the cases and to investigate the occurrence of HO after fracture surgery.
