Based on a series of 120 normal subjects of different gender and age, the geometry of the knee joint was analyzed using a full-length weight-bearing roentgenogram of the lower extremity. A special computer program based on the theory of a rigid body spring model was applied to calculate the important anatomic and biomechanical factors of the knee joint. The(More)
The magnitude of the tissue damage from surgery impacts the trauma response. This response is proportional to the severity of surgical stress. Systemic cytokines are recognized as markers of postoperative tissue trauma. Microendoscopic discectomy (MED) recently has become popular for treating lumbar disc herniations, and is associated with favorable(More)
BACKGROUND We report the outcomes of patients treated with a new arthroscopic treatment modality for knee dislocation after high-velocity trauma. METHODS Twenty-three patients (12 men, 11 women; 25 knees) with traumatic knee dislocation were treated with this technique. Under arthroscopy with gravity inflow irrigation, the ruptured posterior cruciate(More)
The results of surgical treatment of giant cell tumors of the distal radius were reviewed in 12 patients between 1982 and 1995. All 12 patients had Grade III lesions. Six of the 12 patients were treated using intralesional curettage with local excision, and the other six patients underwent en bloc resection with total condyle (four of the six by(More)
We have reviewed 30 patients at a mean of 36 months after free vascularised fibular transfer to reconstruct massive skeletal defects after resection of primary bone tumours. There were 23 malignant and 7 benign neoplasms, half in the lower limb and half in the upper. Arthrodesis was performed in 15 and intercalary bone replacement in 15. The mean fibular(More)
This article summarizes the range and variation of femorotibial alignment, the horizontal orientation of the hip, knee, and ankle joint line, and other pertinent anatomic factors of the lower extremity in normal population groups evenly divided according to gender and age. Although the present data deals only with a two-dimensional frontal plane analysis,(More)
BACKGROUND The literature contains few reports on negative outcomes after thoracoscopic spinal surgery. METHODS From November 1995 to February 1998, 90 patients underwent minimally invasive spinal surgery by thoracoscopic assistance as treatment for their anterior spinal lesions. The diagnoses included 41 spinal metastases, 13 cases of scoliosis, 12 burst(More)
BACKGROUND This study compares the efficacy and safety of percutaneous placement of iliosacral screws between one and two C-arm fluoroscope groups. METHODS This case series contains consecutive 18 unstable pelvic injuries, which were treated with percutaneous placement of iliosacral screws. A single orthopaedic surgeon (K.-T.P.) operated on all these(More)
This prospective study analyzed computer-assisted surgery (CAS) navigation and conventional instrumentation in bilateral total knee arthroplasty. Sixty patients underwent CAS navigation in 1 knee and conventional instrumentation in the contralateral knee randomly. The target zone resided in the reconstructed mechanical axis within a range of 3 degrees varus(More)
The literature includes no studies on the use of video-assisted thoracoscopic surgery in the management of tuberculous spondylitis, and its role in the management of tuberculosis involving the thoracic spine remains unclear. The authors experience with 10 consecutive patients (six women, four men) who underwent video-assisted thoracoscopic surgery for the(More)
