ABSTRACT
OBJECTIVE: To explore the application of three dimensional(3D) CT reconstruction(3D-CT-R) in spinal stenosis and injury of the bone and joint. METHODS: Forty cases were examined with the X-ray film, CT scan and 3D-CT-R. To evaluate their diagnostic value, the images of the three methods were compared. RESULTS: X-ray films could show a visible shift of fracture pieces, but we were sometimes incapable of diagnosing fractures accurately from X-ray and, therefore, we couldn't diagnose fractures located at a special position; the CT scan could show the fractured place with a better result, but it required that doctors should have enough clinic experience, and should be familiar with local anatomy to avoid possible misdiagnosis. CONCLUSION: 3D-CT-R could be used in formulating a particular treatment scheme, and is an ideal examination method.

OBJECTIVE: Pigmented villonodular synovitis(PVS) is a synovial proliferative disorder that remains a diagnostic difficulty. In this retrospective study we evaluated the diagnostic procedures, clinical symptoms and surgical treatment of PVS. METHODS: Six surgically treated cases of PVS were evaluated: five of the lesions were located in the knee joint and one in the hip joint. Diagnosis of PVS was confirmed by histological examination. Operation showed characteristic findings of a joint effusion, and synovial proliferation. RESULTS: Five cases were treated with complete open total synovectomy, and one case received arthoplasty. The followed-up period averaged 3 years and six months (rangeing from 6 months to 6 years). Excellent and good function was seen in all and there was no recurrence. CONCLUSION: PVS diagnosis is frequently delayed due to nonspecific symptoms. Proper treatment includes surgery: extension synovectomy for the diffuse form, and arthoplasty and total joint replacement for the severe bone involvement.
