We report an unusual case of Kirschner wire migration from the proximal humerus into the thoracic cavity and diaphragm which induced pneumothorax and hemoperitoneum. An 81-year-old woman admitted to the emergency room due to sudden onset of dyspnea. X-rays showed pneumothorax and old proximal humerus fracture fixed with rush pins and K-wires. One of K-wires was seen on the diaphragm level at posterior gutter of chest wall. Through the abdomen, K-wire was removed from the diaphragm and a chest tube was inserted. The potential for K-wires to migrate must be recognized, and frequent postoperative radiographic studies have to be performed for the early detection of loosening and migration. It appears that if K-wires are used for fixation of proximal humerus, the lateral ends must be bent to prevent medial migration, and when the desired therapeutic goals have been achieved, these pins have to be susbsequently removed as soon as possible.

PURPOSE To know the functional and radiologic results of the operative treatment for the type I and II tibial plateau fractures according to the methods of internal fixations. MATERIALS AND METHODS Twenty-six patients, who had been treated with open reduction and internal fixation for the type 1 or 2 tibial plateau fractures were evaluated. Twelve cases of type 1 fractures were fixated with 1 lag screw in 5, 2 lag screws in 4 and buttress plate in 3. Fourteen cases of type 2 fractures were fixated with 1 lag screw in 4, 2 lag screws in 6 and buttress plate in 4. The criteria of Hohl and Porter was used for the evaluation of the clinical and radiological results. RESULTS There was no significant difference in the clinical result in type 1 and 2 tibial plateau fractures according to the methods of fixations. And the radiological results were not significantly different in both of type 1 and 2 fractures. CONCLUSION If the anatomical reduction of the articular surface can be achieved, the methods of fixation for the type 1 and 2 tibial plateau fractures do not affect the final clinical and radiological results.
PURPOSE The purpose of operative treatment in acetabular fracture is to restore anatomically the disrupted joint surface and prevent post-traumatic arthritis. We analysed the relationship between the types of the fracture, its location, reduction state with the development of post-traumatic arthritis and hip joint function in postoperative period. METHOD & MATERIAL: A clinical analysis was performed on 14 patients, excluding patients with anterior & posterior wall fracture, with displaced acetabular fracture who had been treated by open reduction and internal fixation. All patients had been followed for minimum 1 year in our department from May 1989, to February 1999. RESULTS The type of acetabular fracture was not correlated statistically with posttraumatic arthritis and Harris hip score. The reduction state of acetabular fracture was significantly correlated with post-traumatic arthritis and Harris hip score. The antomic location of acetabular fracture was not correlated statistically with post-traumatic arthritis but correlated with Harris hip score. CONCLUSION Anatomic reduction is more significant factor in postoperative outcome of acetabular fracture than the type of fracture and the anatomic location of fracture.

PURPOSE : We evaluated the results after the lag screw fixations using A.O. 2.0mm mini screws for the unstable multiple spiral metacarpal fractures. MATERIALS AND METHODS : thirteen cases of multiple spiral metacarpal fractures were treated with the lag screw fixations using 2.0mm mini cortical screws by the recommended technique of AOASIF. TAM of each digit was measured at the time of last follow up and the result was compared with the contralateral normal digits. We also evaluated the amount of shortening, angulation or rotation at the fracture sites on the last follow-up radiographs. RESULTS : Complete radiological unions were obtained in all of the cases. TAM of the operated digits were above 90% compared with those of the contralateral normal digits except 1 case, which had an another fracture and deep laceration at the distal phalanx and proximal interphalangeal joint during the period of follow up. We could not find any shortening, angulation or rotation at the fracture sites on the last follow-up radiographs. CONCLUSION : When we consider that the goal of treatment of the metacarpal fracture is to obtain full motion of the digit through the early mobilization after injury, we think that the lag screw fixation using 2.0mm mini screw is a good treatment modality in the cases of unstable multiple spiral metacarpal fractures.
Type II clavicle fractures have been associated with high rates of nonunion and delayed union. Many authors have supported open reduction and internal fixation of these fractures. Authors analyzed twelve cases of type II distal clavicle fractures which had been treated operatively at department of orthopaedic surgery, Korea university, Ansan and Guro Hospitals from May 1991 to September 1997 and reviewed the result of operative treatment retrospectively. The results were as follows; 1. Among the 12 cases, male was 8, fenale was 4 and the average age of them was 25.6 years. 2. According to the classification by Neer and Rockwood, type IIa was 5 cases and IIb was 7 cases. 3. We treated all the cases operatively, such as C/R with transacromial K-wire fixation in 6 cases, O/R with transacromial K-wire fixation in 4 cases, O/R with coracoclavicular screw fixation in 2 cases. 4. The average follow-up period was 17 months. The functional results were evaluated with Kona classification and showed excellent in 10 cases, good in 2 cases. In conclusion, the operative treatment revealed good functional results in all cases. Authors recommend early operative treatment in type II distal clavicle fractures.

The incidence of the intertrochanteric fracture of the femur is increasing due to increased geriatric population.
The primary goal in the treatment of an order patients with an intertrochanteric fracture is to obtain anatomical reduction and rigid fixation for the rapid mobilization, decreased mortality and restoration of function.
Many devices were developed for this purpose, especially of compression hip screw had gained considerable acceptance.
A retrospective study of clinical results of the 50 cases intertrochanteric fracture from March 1990 to January 1993 was performed.
The result were as follows; 1. Average age is 58 years and sex distribution is 31 cases of male, 19 cases of female.
2. Common cause of injury are slip down and traffic accident. Affected side is Rt 32 cases and Lt 18 cases.
3. According to the classification (of Boyd-Graffin), there are 14 case of Type I, 31 cases of Type II 2 cases of type III,3 cases of Type IV.
4. Among 50 cases, complication is encountered in 8 cases angular deformity (4 cases), limitation of motion(3 cases), infection(1 case).
5. After treatment of intertrochanteric fracture ; Neck-shaft angle of non-displaced fracture and comminuted fracture was an average 2 degree varus angular deformity. Vertical displacement of non-displaced fracture was an average 4.5mm and comminuted fracture was 5.0 mm. Medial displacement of non-displaced fracture was an average 3.5mm and comminuted fracture was 4.5mm.
6. Satifactory results could be obtained by open reduction and internal fixation with compression hip screw.
From March, 1989 to Sept. 1992, total of 31 cases of tibial shaft fracture have been admitted treated with intramedullary nailing at the Department of Orthopaedic Surgery, Ansan Hospital, Korea University.
Among them, 13 cases which had been followed-up than 2years were analyzed and the results were as follows; 1. Among the 13 patients, 9 of them(69.2%) were male, the rest of 4(30.8%)were female.
2. Eight cases out of 13 were open fractures with Gustilo type I-4 cases, type II-2 cases, type III-2 cases and the remaining 5 were closed type.
3. Treatment offered were either interlocking intramedullary nailing(10 cases, 76.9%) or insertion of flexble nails(3 cases, 23.1%).
4. There were no cases with non-union and the average period of bone union was 21.6 weeks.
5. Delayed union and superficial infection occured in each three cases as a complication.
6. Intramedullary nailing could be used carefully in tibial shaft fracture even in the communicated & open fractures.
Acetabular fracture results from high-enegy trauma that cause considerable displacement of the fracture fragments as well as to articular surface of the acetabulum. The goal of surgical treatment is to prevent post-traumatic arthritis and avascular necrosis of femoral head by reconstructing the articular surface accurately and restoring the contact areas between the acetabular and femoral head.
We analyzed 15 patients who were treated with surgical method at Korea University Ansan Hospital from May 1989 to July, 1992 and followed up more than 1 year.
The results were as follows: 1. The most common type was posterior wall fracture in 5 cases(33.3%), transverse fracture in 4 cases(26.7%), both column fracture in 4 cases(26.7), anterior column fracture in 2 cases(13.3%) in sequeuce according to Letournel classification.
2. The most common cause of injury was traffic accident in 13 cases(86.6%), and 2 cases(13.4%) were passengers.
3. There were 9 cases(60.0%)operated within 7th day after injury, 4 cases(26.7%) between the 7th day and 14th day, 2 cases(13.3fo)at the 21st day.
4. The employed surgical approaches were the extended ilio-femoral approach in 7cases(46.7%), the Hocker-Langenbeck approach in 6 cases(40.0%), the ilioinguinal approach in 2 cases(13.3%).
5. The result of treatment was satisfactory in 13 cases(87.7%) and the complications were post traumatic arthritis in 2 cases(15.4%), ectopic ossification in 1 case(6.7%), and avascular necros of femoral head in 0 case.
