In thoracolumbar burst fractures, CT scans demonstrate the narrowing of spinal canal by the retropulsed bony fragments from the vertebral body. A few authors have reported the relationship between traumatic spinal canal stenosis and nerologic deficits. Author analysed the 68 patients with thoracolumbar burst fractures about the relationship between canal stenosis and neurolgic deficits by using CT scans. The results were as follows : 1. Twenty four (62%) of 39 patients with disruption of posterior element had neurologic dificits, while 11 (38%) of 29 patients without disruption had neurologic deficits. 2. Spinal canal ratio of 45% or more at the epiconus level, 52% or more at the conus medullaris level, and 65% or more at the cauda equina level were significant factors for neurologic deficits in thoracolumbar burst fractures. 3. Twenty (87%) of 23 patients with neurologic deficit in epiconus and conus medullarsis level had the horseshoe or crescent shape of patent spinal canal, eleven (69%) of 16 patients with neurologic deficit in cauda equina level had the horseshoe or crescent shape of spinal canal.

Fractures of the ankle joint that involve the tibial plafond result from axial compression and rotational forces causing variable degrees of rnetaphyseal disruption, articular damage, and malleolar displacement. Management of these fractures has been described as difficult and often discouraging. Recommended treatments have included manipulation and cast application, calcaneal traction using pins in plaster or external fixators, vertical transarticular pin fixation, percutaneous pinning of large fragments and immobilization in a plaster cast, fibular stabilization alone, limited open reduction of so-called key fragments, immediate motion with the foot in traction, primary arthrodesis, and even immediate amputation. But, the best results of treatment reported for this fracture have followed early open reduction and rigid internal fixation to restore length, reconstruction of the plafond, primary cancellous bone grafting, tibial buttress plates, early motion, and prolonged non-weight-bearing. We reviewed 40 cases of tibial plafond fractures treated at the Department or Orthopaedic Surgery, Yonsei University, Wonju College of Medicine, during 7 years from January 1980 to December, 1986. The longest duration of follow-up was 5 years and 4 months, the shortest one was 6 months, and the average was 2 years. The results were as follows: 1. Of the 40 cases, male were 32, female were 8. 2. The major causes of the injury of the ankle were fall down and traffic accident. 3. The tibial plafond fractures were classified into 5 types, according to the degree of displacement of the plafond, articular comminution, and metaphyseal disruption. Our cases were relatively in even distribution. 4. Regardless of the types of the fracture, better results were obtained by treatment with open reduction and rigid internal fixation than by any other ones. 5. Complications including superficial wound infection (4 cases), osteomylitis. (2 cases), delayed union (2 cases), non-union (2 cases) were observed. 6. This study suggest that the important variables that influenced the clinical result were the type of fracture, the method of treatment, and the quality of the reduction.

Ganglions are defined as cystic swellings closely connected to joints or tendon sheath, and contain mucinous material. Their most frequent site is the wrist and hand and occasionally they are found at ankle and knee. Some authors had reported rare cases of ganglion occured near the elbow joint which showed neurologic symptom by compressing the ulna nerve. We experienced two cases of ganglion which had occured at the elbow joint. Neurological symptoms were developed by compressing the ulna and radial nerve each sround the elbow joint.

Partial closure of an epiphyseal plate can reduce growth in length and cause angular deformationof the bone. The bone bridge between the epiphysis and the metaphysis, which inhibits growth, can be removed operatively, leaving a cavity, and improvement of the deformity by normal growth is then possible. Previous study have shown that silastic or bone cement diminished both the angular deformity and growth retardation to a highly significant degree. In the present study we wanted to test whether indomethacin and iliac apophysis as an interposition material could prevent bone bridge recurrence following operative removal in adolescent rabbits. It was designed by the concept that cartilage(iliac apophysis) has a specific inhibitory effect on bone formation and indomethacin inhibits bone resorption and bone formation in both heterotopic and orthotopic bone in rabbits. The following experimental groups were designed. Group 1 (N = 7) control group; no interposition material Group 2 (N = 7) iliac apophysis as an interposition material Group 3 (N = 7) only bone wax as an interposition material Group 4 (N = 7) bone wax with administration of indomethacin 10mg/kg/day The results of the study are as follows: 1. In control group, an osseous bridge were revealed as early as 2 to 3 weeks, and this bridging was found consistently in all control groups for the duration of the study. 2. The gmup using iliac apophysis as interposition material was found ineffective for prevention of the formation of epiphyseometaphyseal bone bridge. It was probably resulted from difficulty of its taking from iliac bone. 3. The group using administration of indomethacin after application of bone wax reduced both the angular deformity and growth retardation to a highly significant degree. From the results, it is recommended administration of indomethacin after insertion of silastic or bone cement as an interposition meterial in the elimination of transphyseal closure after physeal damage.
