1/104. spinal cord compression caused by unusual location and extension of ossified ligamenta flava in a Caucasian male. A case report and literature review.

    STUDY DESIGN: A case report of a spinal cord compression caused by ossification of the ligamenta flava is presented together with a review of the literature. OBJECTIVE: To present the diagnosis of ossification of the ligamenta flava in a Caucasian man with a proximal thoracic myelopathy. SUMMARY OF BACKGROUND DATA: This case shows that the upper parts of the thoracic spine can be involved in ossification of the ligamenta flava, which never before has been reported in Caucasian individuals. Furthermore, it is advised that computed tomography scanning and magnetic resonance imaging be combined to provide an accurate diagnosis and proper preoperative evaluation of the bony changes, spinal cord, and compression of the spinal cord. methods: A patient with a thoracic spinal cord compression caused by ossification of the ligamenta flava was treated surgically and made a good clinical recovery. Imaging studies, surgical findings, and results of histopathologic investigations were analyzed to substantiate the diagnosis. RESULTS: The results of the surgical findings seemed to be in contrast with those of the imaging studies. This contrast was occasioned by the uncommon perioperative finding of a fusion of the completely ossified upper and lower parts of the involved adjacent ligamenta flava. Ossification of the ligamenta flava was diagnosed by histopathologic examination, which revealed endochondral ossification and lamellar bone formation without fragments of ligamenta flava. CONCLUSION: Although rarely reported in whites, ossification of the ligamenta flava should be considered in all patients presenting with a spinal cord compression, even at high thoracic levels. The prognosis after decompressive surgery can be good, especially if intramedullary hyperintensities are absent on preoperatively performed T2-weighted magnetic resonance images.

2/104. Preoperative interactive 2D-3D computed tomography assessment of heterotopic bone.

    Total hip arthroplasty is a common orthopaedic procedure in this country. Postoperative heterotopic bone formation may be seen in anywhere from 5% to 76% of such procedures. Only a small subgroup of these patients are symptomatic. Approximately 6% of arthroplasty patients require evaluation of heterotopic bone. In such patients, computed tomography may be useful in staging the extent of bone formation and in helping to plan surgical or radiotherapy treatment. Reformatting transaxial data into coronal and sagittal planar images and into simulated three-dimensional images provides the most comprehensive overview and maximizes communication of relevant findings.

3/104. Ossification of the cervical anterior longitudinal ligament contributing to dysphagia. Case report.

    The authors evaluated the clinical, radiological, and surgical management of ossification of the anterior longitudinal ligament (OALL) that contributed to dysphagia in a patient with simultaneous cervical ossification of the posterior longitudinal ligament (OPLL). A 57-year-old man presented with increasing dysphagia and moderate myelopathy. Imaging studies, including esophagoscopy, revealed marked esophageal compression due to OALL that extended between the C2-5 levels and significant C5-7 OPLL that compressed the distal cervical spinal cord. The use of rongeurs and a high-speed drill facilitated excision of the C2-5 OALL mass, and a routine anterior corpectomy with fusion was performed at the C5-7 level. Postoperatively, the patient's dysphagia and symptoms of myelopathy immediately resolved. The strut graft became fully fused 3 months postoperatively, as demonstrated on dynamic x-ray films, and the patient has remained asymptomatic 4 months postoperatively. patients with dysphagia and coexisting myelopathy benefit from simultaneous surgery for resection of OALL and OPLL masses.

4/104. Using the CLARION cochlear implant in cochlear ossification.

    This paper is a retrospective review of 5 patients with various degrees of cochlear ossification who were implanted with the CLARION Multi-Strategy Cochlear Implant. Preoperative computed tomography scans, intraoperative findings, surgical technique, and hearing outcomes are discussed in a case report format. Full implantation was achieved in all cases by a systematic approach that included drill-through of proximal obstruction (2 cases), scala vestibuli insertion (2 cases), and complete drill-out (1 case). The only complication was delayed wound healing in a patient with sickle cell disease, chronic active hepatitis, and steroid dependency on antimetabolite therapy. Early results show that the 4 patients with at least 3 months of experience have a mean open-set sentence recognition score of 55% and a mean open-set word recognition score of 24%. The conclusion is that implantation of the Clarion device in ossified cochleas can be successful in all degrees of ossification and can provide significant hearing benefit.

5/104. Implantation of the CLARION cochlear implant in an ossified cochlea.

    This report describes the successful implantation of the CLARION Multi-Strategy Cochlear Implant electrode in the totally ossified cochlea of a 5-year-old child via a radical mastoidectomy approach. Postoperatively, the child demonstrated responses to auditory stimuli, even though the electrode array contacted only bone and muscle graft tissue with no visible evidence of nerve fibers or cochlear lumen. Responses to sound did not begin to emerge until 10 weeks following initial stimulation and improved slowly over time. Although the child's postoperative auditory performance is more limited than that of most implanted children, she derives substantially more benefit from her implant than she did from conventional hearing aids.

6/104. Severe heterotopic ossifications after total knee arthroplasty.

    The authors report a case of severe heterotopic ossifications after a total knee arthroplasty in an 83-year-old woman. She showed a dramatic loss in range of motion between the third and sixth postoperative week, after she had obtained a satisfactory 0 degree to 90 degrees--range of motion at the 14th postoperative day. A treatment program of radiotherapy combined with indomethacin and nonaggressive antiinflammatory physiotherapy resulted in a slow but steady improvement with complete relief of symptoms 6 months postoperatively.

7/104. indomethacin-induced postoperative psychosis.

    indomethacin is used commonly for the prevention of postoperatively heterotopic ossification. There have been 3 reports in the pharmacologic literature of indomethacin-induced psychosis. We describe a case of indomethacin-induced psychosis in a patient in whom indomethacin was used for the prevention of postoperative heterotopic ossification after bilateral uncemented total hip replacements.

8/104. Unilateral osseous bridging between the arches of atlas and axis after trauma.

    STUDY DESIGN: This is a case report. OBJECTIVE: To present a case of osseous bridging between C1 and C2 of posttraumatic origin and with an associated closed head injury and to discuss its pathogenesis and clinical outcome after surgical resection. SUMMARY OF BACKGROUND DATA: Heterotopic ossifications of posttraumatic origin in the spine are rare. To the authors' knowledge, no cases have been reported of spontaneous bony bridging between C1 and C2 with a posttraumatic origin. methods: Heterotopic ossifications were detected when pain and limited axial rotation (left/right 10 degrees/0 degree/20 degrees) were persistent, despite intensive physical therapy. Because heterotopic ossifications were ankylosing C1 and C2, the decision was to resect the osseous bridge in combination with a careful mobilization of the cervical spine. Functional computed tomography was performed for analysis of the postoperative results. RESULTS: Four months after surgery, clinical examination showed asymptomatic increased axial rotation. Functional computed tomography indicated that left C1-C2 axial rotation was reduced, possibly related to impingement caused by residual bony spurs. Pathologic changes in the surrounding soft tissue may be another important factor in the persistent limitation of rotation. CONCLUSIONS: Osseous bridging between C1 and C2 may be considered when persistent pain and limited axial rotation are observed after trauma. Operative resection, together with careful intraoperative and postoperative mobilization, may be the treatment of choice.

9/104. Excision and radiotherapy for heterotopic ossification of the elbow.

    radiotherapy has a well-defined role in prophylaxis of recurrent heterotopic ossification of the hip, but has been described infrequently in other situations. This article reports the use of excision and low-dose external beam radiotherapy in three patients with heterotopic ossification of the elbow treated between February 1995 and September 1996. radiotherapy was delivered in a single fraction of 7-8 Gy within 48 hours postoperatively using opposed anteroposterior portals. After a median follow-up of 10.5 months, all three patients demonstrated a significant increase in range of motion without any evidence of recurrence. These results indicate adjuvant postexcision radiotherapy may be used for prophylaxis of recurrent heterotopic ossification of the elbow.

10/104. Ossification in the rectus sheath following free rectus flap.

    Heterotopic ossification (HO) is a rare complication of laparotomy wounds. In this report, we describe an unusual presentation of ossification within the closed sheath following the harvest of a free rectus flap for lower limb reconstruction. Of specific interest to this case is that access to the rectus was gained through a lower transverse approach. Furthermore, the extremities of this incision were utilised for harvest of cancellous bone from the iliac crests. Given that one explanation for HO is intraoperative seeding it is of note that no problem was encountered in the wound intimately associated with the bony disruption.
