Unilateral absence of the articular process at a lumbar vertebra is a rare anomaly. The etiology of the congenital absence of articular process is not precisely determined yet, but it was explained as some of the possible embryologic bases. Absence of the articular process at the level of L5-Sl have been reported a few, but anomaly above L4 is rare. We are reporting a case of absence of articular process at the level of the 4th lumbar vertebra.

The talus is a bone with unique biomechanical features and vascular supply. Although fractures of the talus are not common, the complications of the displaced fractures or dislocation are frequent and resulting disabilities are so severe that the importance of proper management is emphasized. Authors analyzed 17 cases of fracture-dislocation of the talus, treated at Soon Chun Hyang University Hospital from January 1983 to December 1988. The results were as follows:l. Among the 17 cases, there were 15 males and 2 females and the average age was 28 years old, ranged from 21 years to 58 years. 2. The causes were fall from height in 10 cases, traffic accident in 6 and others in one. 3. According to Marti-Weber classification, 2 cases were type I, 5 in type II, 7 in type III and 3 type IV. 4. Among the 17 cases, 9 cases in type I and II were treated conservatively, and 8 cases in thpe III and IV were treated operatively. 5. Complications were avascular necrosis in 3 cases, degenerative arthritis in 4 and nonunion in 1. 6. Final results, evaluated by the criteria of Mindell et al., were as follows: excellent in 7 cases, good in 5, fair in 3 and poor in 2.

Intradural lipomatosis is a rare clinical entity characterized by excessive fat deposition in the intradural space. And they occur slightly more frequently in males. It may lead compression of the spinl cord or lumbargo, radiating pain, paresthesia, intermittent claudication and if they involve the cervical and thoracic region, the patients with tumours in these regions most frequently present with a slow ascending monoparesis or paraparesis, cutaneous sensory loss and defective deep sensation. Only 3% of tumours have been reported in the thoraco-lumbar region. The diagnosis should be based on a combination of clinical, imaging, surgical, and histological findings, and especially the diagnostic procedure of choice in patients with progressive myelopathy is MRI scan as it produces accurate imaging without exposure to ionizing radiation. He was treated surgically-removal of excessive fat tissue and decompressive laminectomy. We report a case of intradural lipomatosis that we had removed by surgically.

A fracture of the distal tibial articular surface is fortunately an uncommon injury, since it can be exeptionally difficult to manage. The term plafond is gar'nering general acceptance since there is no anatomic name for the specific location of this fracture. The term was introduced more than 50 years ago in American orthopaedic literature to describe these injuries. The literal meaning of plafond is the underside of a floor, i.e., a ceiling, so the term refers to that portion of the distal articular surface of the tibia which articulates with the superior articular surface of the talus. It excludes the medial malleolar joint surface. Fracture of the plafond have also been called compression, pylon, Malgaigne and explosion fractures. A plafond fracture is defined as one caused primarily from direct axial compression resulting in elevation andgor displacement of all or part of the distal articular surface of the tibia, excluding isolated or combined fractures of the medial and posterior malleoli that are recognizably caused by rotational forces. We reviewed 16 cases(14 patients) of tibial plafond fractures treated at the Department of Orthopaedic Surgery of Soan Chun Hyang University Hospital during 8.5 years period from June 1974 to December 1982. The longest duration of follow-up was 5 years and 6 months, the shortest, 6 months, and the average, 1 year and 6 months. They were classified according to Moore et al., and assessed according to the criteria of Joy et al. The following results were obtained: l. Of the 14 patients, male were 12, female were 2. 2. The average age of the patients was 38 years old. 3. The most common causative injury was fall-down. 4. The most common type in radiological study was dorsiflexion type. 5. In method of treatment, operative treatment was done in 9 cases and non-operative in 6 cases. 6, The average duration of the cast immobilization in non-operative treatment was 12 weeks and operative, 10 weeks. 7. Better results were obtained by operative treatment than non-operative treatment. 8, The complications were encounted in 1 case of non-operative, 2 cases of operative treatment. 9. We agree that the accurate anatomical reduction with rigid internal fixation assures better results in the tibial plafond fracture.

Complete decompression is very important for the surgical treatment of the spinal stenosis. But it may produce the segmental instability or spondylolisthesis as postoperative complications. So rigid internal fixation is mandatory to reduce this problem. Authors treated 16 cases of spinal stenosis by complete decompression and pedicale screw fixation and posterolateral fusion, analyzed 11 cases which were followed more than 9 months. The results were as follows: 1. Among the 11 cases, the mean age was 49 years old and there were 5 males and 6 females. 2. The most common cause was degenerative type, 7 cases. The most frequent level of involvement was L4–L5, 10 cases and two level involvement was 3 cases. 3. Among the 11 cases, 6 cases were excellent and 4 cases were good, and 1 case was fair, in Hanley's criteria. 4. In spondylolisthetic stenosis, the average percentage of slippage was changed from 22% pre-operatively to 2.7% postoperatively and 3.8% after 9 months follow up. 5. The complications were relatively few(1 case of hematoma and 3 cases of pain on the bone graft donor site).
