Thirteen cases of concomitant hip and shaft fractures of the same femur are reported. The hip fractures was initially missed in one case. Osteosynthesis of both fractures was performed in twelve cases. One except was 12-year-old boy who was managed hip with two Knowles pins and shaft conservatively. Both fractures healed in all followed for average 5.3 months or more. Osteosynthesis of both fractures is recommended as soon as the patient is in a stable condition, preferably by early fixation with AO principle or IM nailing in selected cases.

This study was performed to investigate the distribution and magnitude of stress at supporting tissue of abutment teeth and residual ridge tissue with remaining unilateral posterior teeth. Four types of removable partial dentures that included clasp retained removable partial denture, attachment retained removable partial denture, telescopic removable partial denture, and swing-lock partial denture were designed, and strain gauge was used for stress analysis. Each prosthesis was subjected to simulated vertical and oblique load. The following conclusions were drawn from this study. 1. The clasp retained removable partial denture generally distributed simulated vertical force more evenly to the supporting structure. 2. The stress at buccal side of 1st premolar was the lowest in swing-lock partial denture and that was highest in attchment retained removable partial denture. The stress at lingual side of 1st premolar was the lowest in telescopic partial denture. 3. In clasp retained removable partial denture, stress was lower at load site and ridge crest at midline, but it was higher at lst premolar area on vertical load. 4. In attachment removable partial denture, stresses at buccal side of 1st premolar, lingual side of 1st premolar on vertical load, and ridge crest at midline on oblique load were higher. 5. In telescopic removable partial denture, stress at lingual side of 1st premolar was the least in all removable partial dentures, but the stress at load site was higher. 6. In swing-lock removable partial denture, stress at buccal side of 1st premolar was the lowest, and stresses at load site and distal end of residual ridge crest were higher.

We reviewed 23 patients of injury to the spine who were under 15 years of age and treated at Wonju Christian Hospital from January, 1978 to December, 1987. The patients were classified into 3 different categories, that were frsctures(17 cases), dislocations(3cases), and fracture-dislocation(3 cases). We analyzed the cause of injury, sexage distribution, treatment and neurological injuries. The results were as follows : l. Among the 23 cases, there were 16 boys(70%) and 7 girls(30%). The mean age was 11 years of age, and ages of active period, that is 10 to 15 years of age, were most common, 17 cases(74%). 2. The most common cause of injury was fall from a height, 13 cases(57%). The most common location of injury was cervicsl spine, 10 cases(43%) and among these cases, injury to upper cervical portion(C1–C3) was more common than lower cervical portion(C4–C7). 3. The cases of multiple compression fracture were 6 patients(26%), and all cases were located thoracic or thoraclumbar junction. 4. Most cases were stable spinal injury, 18 cases(78%), and the most common mechanism of injury were compreesion injuries due to hyperflexion, 15 cases(65%). 5. The most common associated injury was head injury, 9 cases(39%), and associated neurological complications were in 4 cases, 3 cases of these were recovered. We could ascertain that the prognosis of children spinal cord injury is better than that of adult. 6. Restoration of the height of the involved vertebral bocy occurred in all but one compression fractures of vertebral body. 7. There were 3 cases of epiphyseal injury, 2 of these were epiphyseal separations of odotoid process of atlas, the other was fracture of lumbar vertebral apphysis. 8. All but two were treated conservatively and the results were good. In stable spinal injury, we considerded that the duration of treatment was 4 to 6 weeks.

Peri-tarsal dislocation occurs rarely and it has a complex joint structure anatomically. So, the injuries of the tarsal joint include many bony and ligament injuries and many complications such as pain on weight bearing and limitation of joint motion. The authors have reviewed a series of 15 cases of Peri-tarsal dislocations and the results obtained are as follows;1. Among the 15 cases of peri-tarsal dislocations, subtalar dislocation were 2 cases, Chop-art dislocation was 1 case, Lisfranc dislocation were 11 cases, and pure ankle dislocation was 1 case. 2. There were 12 cases of associated tarsal bone fractures 6 cases were cuneiform fractures, 4 cases were navicular fractures, and 2 cases were cuboid fractures 3. The clinical and radiological result of treatment was good in 3 cases, fair in 6 cases, and poor in 6 csses. 4. The cause of poor results were open dislocation, associsted tarsal bone fractures, delay of treatment, unstable reduction, and associated long bone fractures. 5. The most common complications after treatment were pain on weight bearing and limitation of joint motion.

Nonunion is extremely rare in children, Weber et al. concluded that considerable skill is required to induce nonunion in a child and its occurrence always results from a serious error in management. Twenty-six cases of delayed union and nonunion examined and treated at department of Orthopedic Surgery, Yonsei University, Wonju College of Medicine during the period of 1970 to 1988 was observed and analysed. 1. Of the 26 cases, there was 18 male and 8 female patients. The results showed more predominence of male over female patients. 2. Delayed union and nonunions commonly occurred over 5 year of age. 3. The causes of the fractures consisted of 12 Fell from heights, 5 Traffic accidents and others. 4. Of the 26 cases, there were 21 closed fractures and 5 open fractures. 5. Prior to admission to this hospital, 15 were treated conservatively and 10 treated operatively, and one received no treatment at all. 6. The sites of delayed union and nonunion were 10 phalanges, 6 tibia, and 3 ulna in order. 7. Probably causes of the delayed union and nonunion were unsatisfactory immobilization in 13 cases, infections in 6 cases, operative complications in 6 cases, interposition of the soft tissues in 2 cases in 2 cases, persistent seperation of the fragments in 1 case. 8. We are considered that the treatment of the nonunion must be individualizd but usually requires eradication of any infection, excision of the intervening fibrous tissue, bone grafting, and internal fixation.
