Bilateral Simultaneous Heterotopic Ossification of the Reflected Head of Rectus Femoris Muscle: A Case Report and Review of the Literature

Abstract

Lamellar bone formation in an abnormal location is defined as heterotopic ossification. It commonly occurs around the hip joint and most often involves the abductor muscles. It is a benign condition; however, its etiology remains largely unknown. Most previously reported cases have been due to trauma or intramuscular hemorrhage. In this paper, we present a case of bilateral heterotopic ossification of the reflected head of rectus femoris muscle without antecedent trauma or any other known cause, as the first and unique case in the literature. She was treated by excision of the right symptomatic bony mass via a modified Smith-Petersen approach. Postoperatively, she received 75 mg indomethacin daily for six weeks. She was pain-free and obtained full range of motion 3 weeks after the first intervention.

Heterotopic Ossification of the Triceps Muscle after Internal Fixation of Proximal Ulna Fracture: A Case Report

“…In this case, the result of surgical excision was similar to the previous data [17,22,[33][34][35][36][37].…”

“…From this experience, we do not recommend isolated physical therapy in patients with elbow injury, rather we recommend combined physical therapy with other preventive measures. Many authors agree that if ectopic bone around the elbow is causing or contributing to a loss of functional elbow motion, an operative procedure is warranted to remove the offending bone and release the joint capsule whether the motion limitation is partial or complete [17,22]. Results of surgical excision of heterotopic ossification about the elbow have shown significant improvement in range of motion, independence, and quality of life in most cases [22,[33][34][35][36][37].…”

“…It causes pain, swelling and is usually associated with limited range of motion. That is why, this is an important problem throughout orthopaedic surgery [13][14][15][16][17][18][19].…”

Counterstrain as a Diagnostic and Treatment Tool for Rectus Femoris Origin Injuries: A Case Report

“…9 Acute RFO injuries stemming from the reflected head have been reported. [10][11][12][13] Unfortunately, current guidelines are not well defined regarding At the time this manuscript was submitted and reviewed, Dr. Goering chaired the American Academy of Osteopathy's Publications Committee, which oversees publication of The AAO Journal. The doubleblind review process prevented reviewers from knowing the authors' identities.…”
