1/17. Solitary exostosis of the thoracic spine. early diagnosis and treatment.

    STUDY DESIGN: A case report. OBJECTIVE: To highlight the importance of early diagnosis and treatment of vertebral exostosis. SUMMARY OF BACKGROUND DATA: Few cases of spinal cord compression caused by solitary thoracic exostoses have been reported. METHOD: A solitary exostosis in the midline of the neural arch of the fifth thoracic vertebra, causing compression of the spinal cord documented on both magnetic resonance and computed tomographic examinations, is reported in a 51-year-old woman who had normal findings in a neurologic examination. RESULTS: The exostosis was successfully excised. CONCLUSION: Accurate preoperative diagnosis of vertebral exostoses is possible using magnetic resonance and computed tomography. Early excision avoids the development of a permanent neurologic deficit.

2/17. A rare case of enthesopathy of the bicipital tuberositas of the radius.

    We present a case of a patient with complaints in both elbows, due to a prominent bicipital tuberosity with an enlarged bursa, in which operative resection was successful.

3/17. Symptomatic bursa formation with osteochondromas.

    Two cases of bursa formation in association with osteochondromas are presented. This condition may be confused radiographically and clinically with malignant transformation of the cartilage cap. Ultrasound examination on one of the patients proved helpful in arriving at the correct preoperative diagnosis. ultrasonography was also helpful to the surgeon with regard to size and extent of the bursa.

4/17. popliteal artery thrombosis secondary to exostosis of the tibia.

    This report describes an exceptional case of popliteal artery thrombosis secondary to exostosis of the superior extremity of the superior tibia in a young adult. Correct diagnosis was made during re-operation for recurrent thrombosis. Surgical treatment consisted of resection of the bony tumor and venous bypass to reestablish arterial continuity. Femoropopliteal vascular complications of exostosis are rare, with most cases involving arterial aneurysms or false aneurysms. Differential diagnosis in our young patient took into account the other causes of popliteal thrombosis: entrapped popliteal artery, adventitious cyst, fibrodysplasia, and juvenile arteriopathy. In patients with major functional disability, operative treatment is recommended to remove the bony abnormality and repair the arterial lesion.

5/17. Exostosis following a subepithelial connective tissue graft.

    This case report describes the formation of an unusual unaesthetic gingival enlargement during a five year post operative period subsequent to a subepithelial connective tissue graft placed facial to teeth #4 and #6. Histological assessment of the enlarged tissue indicated that it consisted of viable bone and marrow. The exostosis was reduced with rotary instruments and acceptable soft tissue aesthetics were created using a carbon dioxide laser for gingivoplasty. Possible causes for this unusual enlargement are discussed.

6/17. Ossicular discontinuity and exostoses in proteus syndrome: a case report.

    proteus syndrome (PS) is a rare hamartomatous disorder characterized by mosaic overgrowth of multiple tissues that manifests early in life and is progressive. The presence of unilateral external auditory canal exostoses in a patient who is not a swimmer or surfer is suggestive of PS. However, hearing loss is not a typical feature. Here, we describe exostoses and ossicular discontinuity with conductive hearing loss in a patient with PS. The treatment consisted of canalplasty and ossicular chain reconstruction. A postoperative reduction was demonstrated in the patient's air-bone gap, from 21 dB to 13 dB for the pure tone average (four frequencies) and from 41 dB to 15 dB in the high-frequency range (6,000 to 8,000 Hz). Causes of ossicular discontinuity are discussed. Routine annual audiometric and otolaryngological evaluation should be considered in all patients with temporal bone involvement of PS.

7/17. Subungual exostosis: a review of 16 cases focusing on postoperative deformity of the nail.

    We reviewed the clinical features of 16 patients who underwent surgery for subungual exostosis, focusing on postoperative deformity of the nail. In 7 patients, the lesion did not destroy the nail bed and was excised with a fish-mouth-type incision. In 9 patients, the lesion destroyed the nail bed and was excised with a direct approach. In 5 of the 9 patients, artificial skin was applied after excision of the tumor because the defect of the nail bed was large. Good postoperative appearance of the nail was obtained by a fish-mouth-type incision when the tumor did not destroy the nail bed, although 2 patients had local recurrence. onycholysis occurred postoperatively when the tumor destroyed the nail bed and the defect of the nail bed was large after excision of the tumor. Secondary nail bed reconstruction may be indicated in such cases with postoperative deformity of the nail.

8/17. Bony exostoses developed subsequent to free gingival grafts: case series.

    Bony exostosis (BE) is described as a benign localised overgrowth of bone of unknown aetiology. Buccal bony exostosis (BBE) development secondary to soft tissue graft procedures has been reported in a small number of cases. The dental literature describes BBE development also at sites where free gingival grafts (FGG) have been used to increase the amount of gingiva. The following case series describes BBE development at nine sites (five cases) at which FGG was performed to increase the width of the attached gingiva. The presence of exostoses has been recognised during postoperative visits. Histological examination revealed osseous enlargements compatible with the diagnosis of exostoses at two re-entry procedures. In conclusion, based on previous reports, periosteal trauma, eg fenestration, seems to be the main aetiologic agent associated with the development of BBE in areas where FGG were placed.

9/17. The value of three-dimensional computed tomography in diagnosis and management of Jacob's disease.

    This study reports a case of Jacob's disease characterized with limited mouth opening due to bilateral coronoid hyperplasia forming pseudojoints with zygomatic arches. Magnetic resonance (MR) examination of temporomandibular joint (TMJ) is usually the imaging method chosen in patients with such symptoms. However, the coronoid processes can not be displayed because they are not included in field of view in MR imaging of TMJ. For that reason, these patients may be treated for a misdiagnosis of TMJ disorders. In this study, the aetiology and diagnostic methods of Jacob's disease, the pre-operative/post-operative role of three-dimensional computed tomography and some measurements used in diagnosis were evaluated.

10/17. The CT appearance of avulsion of the posterior vertebral apophysis. A case report.

    Avulsion and posterior dislocation of the posterior dislocation of the posterior part of the vertebral apophysis is a rare condition, occurring mainly in adolescence. If the avulsed part is ossified it may be diagnosed with conventional x-rays including myelography. The present case shows that CT scan with sagittal reconstruction gives exact information of the nature of the lesion as well as its extension into the spinal canal, and that CT alone is sufficient for preoperative diagnosis.
