Heterotopic ossification of Achilles tendon is known to be related with history of prior Achilles tendon surgery, trauma, Achilles tendon rupture. We report a case of heterotopic ossification of partially ruptured Achilles tendon and treated by surgical removal of ossification and V-Y advancement with tendon repair.

Purpose: To evaluate the effect on clinical course of heterotopic ossification of distal tibiofibular syndesmosis after ankle fractures. Materials and Methods: From June 2001 to May 2004, we found nine cases of heterotopic ossification of distal tibiofibular syndesmosis after ankle fractures. There were 8 male patients and 1 female patient; their mean age was 42 years old. There were 6 Weber type B and 2 Weber type C fractures, and there is 1 case with posterior malleolus fracture only. Among them, 8 ankle fractures were operated. Follow up period was averaged for 14 months. We were able to review radiographs at initial injury and to review clinical menifestation and radiographs at last follow up. We used an ankle-hindfoot scoring system of AOFAS which combined symptom, function and alignment with maximum score of 100 point. Results: In all cases ankle dorsiflexion and plantarflexion were not significantly different from that of the contralateral side. The patients who had developed heterotopic ossification in distal tibiofibular syndesmosis had a similar functional score. The mean ankle-hind foot score was 94 points. Conclusion: We concluded that the heterotopic ossification of distal tibiafibular syndesmosis after ankle fractures had little effect on clinical course and range of motion of ankle joint.

The incidence of heterotopic ossification in adolescents appears to be lower than in adults. There exist very few reports of heterotopic ossification with total bony ankylosis in child or adolescent populations. We describe a case of total bony ankylosis of the elbow secondary to heterotopic ossification, in a 14-year-old female. Total ankylosis of the elbow at 45 degrees of flexion was noted 6 months postsurgery, and complete surgical excision of the heterotopic mass was performed. After an additional one-time dose of radiation therapy and nonsteroidal anti-inflammatory drug medication, full range of motion was obtained without any recurrence or other complications, up to the last follow-up of 30 months.

Heterotopic bone formation in abdominal incisions is a recognized but uncommon sequela of abdominal surgery. On the other hand, the formation of ectopic bone is a well-recognized complication following arthroplasty of the hip. Heterotopic ossification of midline abdominal incision scars is a subtype of myositis ossificans traumatica. Ectopic bone formation of midline abdominal incisions may cause regional pain or discomfort in the patient after surgery. If symptomatic, treatment is complete excision with primary closure. Radiologically, it is important to distinguish this benign entity from postoperative complications. We report a 69-year-old male who underwent exploratory laparotomy for traumatic small bowel perforation. A segment of abnormal hard tissue was found in the abdominal wall. Heterotopic ossification may occur at various sites and is a recognized but infrequent sequela of exploratory laparotomy. This case highlights clinical and etiological features of this finding.

We report the case of a heterotopic ossification in the subscapularis muscle. A 30-year-old woman was diagnosed as a heterotopic ossification in the right subscapularis muscle. X-rays, a CT scan and a MRI showed bone-like lesions in the muscle. The location of the ossification was both inferior and anterior to the joint. The mass nearly bridged between the proximal humerus and the inferior portion of the coracoid process. Symptoms did not respond to rest, NSAIDs for 3 months and to stretching exercises treatment for 6 months. Excision and biopsy was performed through deltopectoral approach. Disodium Etidronate was administered during the postoperative period. She regained normal range of motion postoperatively and improved in the shoulder pain after performing strengthening exercises with Therabands. We think that a cause of limitation of the shoulder was impingement between the mass and the coracoid process, and that another cause was adhesion between the mass and the joint capsule. We conclude that excision and postoperative rehabilitation exercises are good methods for a heterotopic ossification in the subscapularis muscle for those that are nonresponsive to nonoperative treatments.

Heterotopic ossification is often complicated in patients with brain injury. It occurs in the connective tissue of skeletal muscle close to a joint, especially most highly in the hip joint. This study have reported a case of heterotopic ossification in hypoxic brain damage patient due to cardiac attack. Binso-san is known by medication on arthritis. It has an effect on pain control or reduce of swelling in the joints. This study suggest that Binso-san has an improving effect on hip joint affected by Heterotopic ossification.

Heterotopic ossification is the formation of extra-skeletal bone in the muscle and soft tissues, and an osteoma is a benign bone-forming tumor composed of compact or mature trabecular bone limited almost exclusively to the craniofacial bones. This paper reports an extremely rare case of heterotopic ossification mimicking an osteoma that occurred independently at the plantar side of the medial sesamoid bone. The patient was a 46-year-old male with a three-month history of pain and a hard mass on the plantar aspect of the left forefoot sole. After excising the lesion, the patient's symptoms were relieved, and no pain or complications occurred. This paper discusses this exceedingly rare case of heterotopic ossification around the medial sesamoid bone with a review of the relevant literature.

Fibrodysplasia ossificans progressiva is a rare hereditary disorder characterized by progressive heterotopic ossification in muscle and connective tissue, with few reported cases affecting the head and neck region. Although plain radiographic findings and computed tomography features have been well documented, limited reports exist on magnetic resonance findings. This report presents 2 cases of fibrodysplasia ossificans progressiva, one with limited mouth opening due to heterotopic ossification of the lateral pterygoid muscle and the other with restricted neck movement due to heterotopic ossification of the platysma muscle. Clinical findings of restricted mouth opening or limited neck movement, along with radiological findings of associated heterotopic ossification, should prompt consideration of fibrodysplasia ossificans progressiva in the differential diagnosis. Dentists should be particularly vigilant with patients diagnosed with fibrodysplasia ossificans progressiva to avoid exposure to diagnostic biopsy and invasive dental procedures.

Heterotopic ossification (HO) within the substance of the subscapularis tendon is a rare lesion which remains a poorly described condition with little known of the exact mechanisms involved. Furthermore, its clinical importance remains still unclear. To our knowledge, there are no studies present to data regarding HO within the substance of the subscapularis tendon, even with resultant isolated complete tear of the subscapularis tendon. Here we present a case of huge HO associated with unusual isolated complete tear of subscapularis tendon concomitant with tear of biceps long head tendon. After arthroscopic debridement for the complete tear site of biceps long head tendon, mini-open excision of the ossification and subscapularis repair with suture anchor fixation were performed. The patient showed complete recovery of strength and function of the subscapularis at subsequent 24 months follow up.
