Ossification, Heterotopic*

Heterotopic ossification is defined as a reactive disease with mature lamellar bone formation in soft tissue. We experienced a case of heterotopicc ossification occurred on the thenar eminence and the thumb without trauma. We report this rare case with a review of the relevant literature.

PURPOSE: To evaluate the usefulness of wire fixation in displaced acetabular fractures. MATERIALS AND METHODS: From January 2000 to December 2005, 19 cases of displaced acetabular fracture were treated with wire fixation. According to Letournel's classification there were 9 both column fracture, 5 transverse fracture, 3 anterior column with posterior hemitransverse and 2 T-type fracture. Only wire fixation in 13 cases and wire with plate or wire with screw fixation in 6 cases. RESULTS: We evaluate the accuracy of reduction by Matta' criteria, anatomical reduction in 12 cases, incomplete reduction in 4 cases, poor reduction in 2 cases and surgical secondary congruence in 1 case. The clinical results showed excellent in 12 cases, good in 4 cases, fair in 2 cases and poor in 1 case. The radiological results showed excellent in 10 cases, good in 4 cases, fair in 3 cases and poor in 2 cases. There were 4 cases of complication; wound infection in 1case, post-traumatic arthritis in 1 case and heterotopic ossification in 2 cases. CONCLUSION: The cerclage wiring is a preferable method in internal fixation of displaced acetabular fractures that can facilitate reduction and achieve stable fixation.

PURPOSE: We analyzed the clinical results of surgical treatment in patients with post-traumatic stiff elbow. MATERIALS AND METHODS: We performed surgical release in 22 elbows with posttraumatic stiffness of extraarticular origin. The average preoperative arc was 48.3 degrees, with an average flexion contracture of 39.5 degrees and an average further flexion of 87.2 degrees. Depending on their radiographic findings, cases were divided on the basis of whether ectopic ossification was present (16 cases) or not (6 cases); and as to whether the articular surface was involved (11 cases) or not (11 cases). The postoperative final arc and ratio of desired gain were compared between the groups. RESULTS: The average final arc was 108.9 degrees in the ectopic ossification group and 85.7 degrees in the non-ectopic ossification group, and showed a significantly higher arc in the ectopic ossification group. The ratios of desired gain were 89.3% and 62.6%, respectively, being significantly higher in the ectopic ossification group. In terms of articular surface involvement, no significant difference was observed between the two groups. CONCLUSION: When performing operative treatment for post-traumatic stiff elbow, assessment of the cause plays an important role. In case of ectopic ossification, satisfactory results can be expected with operative treatment after the ectopic bone has matured.

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.

Rupture of sciatic nerve is a rare injury in minimally displaced pelvic bone fracture. We report one case of complete rupture of sciatic nerve that were resulted from the extremely protruded Kuncher nail inserted before accident and the preexisting heterotopic ossification with a review of the relevant literature.
