an extremely rare case of extensive myositis ossification: complete extra-articular ankylosis of hip joint

Myositis ossificans, in its literal translation, is defined as an inflammatory ossification of muscle and the neighboring soft tissues. a rare case of post-brain injury ossification of the gluteus maximus muscle extending from the greater trochanter of the femur to the right wing of the iliac bone, leading to extra-articular bony ankylosis of the hip is reported. a 40-year-old male presented to the outpatient department with a stiff right hip and restriction of its movements. the patient had a history of cerebral hemorrhage 18 months back and subsequently developed stiffness in the right hip since the last 3 months. x-ray and ct scan revealed the extension of an ossified bar extending between the lateral aspect of the right iliac wing above the right acetabulum and upper 1/3 of the anterior lateral aspect of the femur near the greater trochanter, measuring 1003240 mm. the patient was then allowed to go for rehabilitation with appropriate physiotherapy and anti-inflammatory drugs. extensive hypertrophic ossification can occur at a totally unrelated site as a consequence of cerebral insult/ head injury.
