Myelopathy or dysfunction of the spinal cord, can be caused by degenerative processes of the cervical vertebrae. Cervical spondylotic myelopathy can be divided into five distinct syndromes on the basis of clinical presentation by Ferguson. Absolute indication for surgery is the progression of neurologic deficit. Decompression may be achieved using an anterior, posterior, or a combined approach, but each patient has unique clinical conditions that require individualized treatment. The purpose of the study was to evaluate the operative results by the clinical manifestation. In evaluating the results, the evaluation system established by the Japanese Orthopedic Association was employed. The average preoperative score in the 14 patient was 8.7 points and the average postoperative score was 12.7 points. The better results have been obtained for those who were managed with decompression within 1 year after onset of symptoms and those who had lateral type. In conclusion, the prognosis for the recovery of the spinal cord function is related with the onset of clinical symptoms and degree of neurological deterioration, so early detection and operative decompression for cervical spondylotic myelopathy may be the best method for the prevention of those unwanted and potentially devastating neurological deteriorations.

Surgical stabilization using instrumentation for thoracolumbar injuries offers several advantages such as nearly anatomic reduction of fractures, protection of neurologic structures and most importantly early ambulation of the patient. The treatment of fracture-dislocation of the thoracolumbar spine has been progressively improved over the past decades and recently a lot of new device have been introduced to improve fixability of the involved vertebrae three dimensionally and short segmental fixation as possible. The authors have treated 17 cases of unstable thoracolumbar fracture using Cotrel-Dubousset instrumentation in the Department of Orthopedic Surgery, Kangdong Sacred Heart Hospital from Jan. 1988 to Jan. 1989 with the following results: 1. Bursting fractures are the most common type(52.9%) of mechanism of injury. 2. Excellent anatomic reductions were obtained and compression, wedging and local kyphotic deformities were nicely corrected. 3. Short segmental fixation can preserve the maximal spinal mobility. 4. No significant loss of reduction or loosening of implant was found. 5. Remarkable neurologic recoveries were observed in cases of incomplete cord lesion. 6. Significant neurologic recovery was found in patients treated with laminectomy and Cotrel-Dubousset instrumentation.

Fractures of the tibial condyles, involving as they do weight-bearing articular surfaces and frequently accompanied by soft tissue injuries such as collateral ligaments, cruciate ligaments, and menisci present a variety of problems in treatment and prognosis. Slee, Apley, and others maintained the opinion that most fractures of the tibial condyles could be managed conservatively. On the other hand, Rombold, Schatzker, and others seemed to consider closed treatment to be virtually s form of therapeutic nihilism and adviced open reduction. But recently most authors agree that the method of treatment has to be selected in each individual case, and recommand anatomical reduction of the fracture as possible and early knee motion. The authors have treated 17 cases of tibial condylar fractures with arthroscopic management and extraarticular distal approach in the Department of Orthopedic surpery, Kang Dong Sacred Heart Hospital from Oct. 1986 to Jul. 1989. Of the above cases, 11 cases could be followed for a period of anywhere from 1 year to 31/2 years and analysed according to the cause, classification, treatment, and result. The following results were obtained from the analysis of 11 tibial condylar fractures. l. Of the 11 cases, 7 (63.6%) were male and 4 (36.4%) were female. 2. Of the 11 cases, 7 (63.6%) were due to traffic accident (5 pedestrians, 2 occupants) and 3 (27.3%) were due to fall from height. 3. Among 11 cases, 7 (63.6%) were associated with other injuries. 4. Bone graft was needed in 5 cases. 5. All were treated by arthroscopic management with anatomically and functionally good results. 6. By arthroscopic mangement, it was easy to find and treat the accompanying intraarticular lesion. 7. With early active and C.P.M. exercise, almost full range of motion was obtained in all cases.

Isometric positioning of the ACL graft is an important consideration in successful reconstruction of the ACL-deficient knee. The purpose of this study is to get a certain guideline in the endoscopic one-tunnel technique of anterior cruciate ligament reconstruction by measuring the skin angle and determine the degree of minimum flexion of the knee joint during femoral tunneling and interference screw fixations. To get the guide lines, first we get the tibial tunnel angle parallel to the Blumensaat's line from fully extended lateral knee joint radiography. Secondly measure the differences between angles of the femur-tibia shaft and anterior thigh-leg skin. Then measure the minimum femur-tibia flexion angle does not perforated the posterior cortex of the distal femur during femoral tunneling. Intraoperative measuring the angle between interference screw guide pin and tibial tunnel to get the parallelism of the femoral tunnel and interference screw. The results were as follows; The average femur-tibia shaft angle with 30degrees anterior thigh-leg skin angle was 30.2+/-1.75degrees, with 45degrees was 45.2+/-1.23degrees, with 60degrees was 61.9+/-4.23degrees, with 75degrees was 78.6+/-2.62degrees, with 90degrees was 97.8+/-3.96degrees. Predetermined sagittal tibial tunnel vector on the 0degrees extension knee joint lateral radiographs were applied to the several knee joint dynamograms. The mean minimum flexion angle of the femur-tibia shaft that doesn't perforate the posterior cortex of the femur was 45+/-1.58degrees (male), 44.5+/-4.97degrees (female). The average angle between interference screw guide pin and tibial tunnel was 23.0+/-2.23degrees. The findings of the present study suggest that anterior thigh-leg skin angle can be used instead of the true femur-tibia shaft angle. Less knee flexion angle makes good arthroscopic view during the tibio-femoral tunneling and interference screw fixation.

About half of all burst fractures at the thoracolumbar junction lead to neurological impairment and several clinical series have demonstrated a statistically significant correlation between canal encroachment and neurologic impairment, but not directly related. Spontaneous canal remodelling over time due to bone resorption has been observed in conservatively treated burst fractures. The aim of this study was to measure spinal canal remodelling after stabilization of burst fractures. So, we evaluated 22 cases of surgically stabilized burst fractures of thoracolumbar junction about pre and postoperative spinal canal stenotic ratio and canal remodelling by bone resorption over time. The results were as follows; l. Pedicle splaying increases the spinal canal area and necessitates correction. 2. Patients with neurological deficits had average 53% encroachment and the neurological normal patient had a canal compromise of 33.9%. 3. Postoperatively canal encroachment had decreased to a mean of 17.4% and further reduced by resorption of bony fragment to a mean of 8.3% within 14 months. In conclusions, remodelling of the spinal canal by resorption of encroaching bone fragments is a consistent feature in surgically stabilized thoracolumbar burst fractures and most patients regain their prefracture canal demensions within 14 months.
