The purpose of this paper is to compare the results, complications, advantages and disadvantages of treatment by flexible intramedullary nail with those by interlocked intramedullary nail in humeral shaft fractures. The authors analyzed 42 cases of humeral shaft fractures in patients who were treated by intramedullary nailing. Nineteen patients were treated with flexible I-M nail and twenty three patients were treated with interlocked I-M nail. Fourteen cases(74%) treated with flexible I-M nail were obtained primary bone union, and twenty one cases(91%) treated with interlocked I-M nail were obtained primary bone union. Five cases treated with flexible I-M nail and 2 cases treated with interlocked I-M nail failed union and the most common cause of nonunion was distraction. Flexible I-M nailing does not solve rotational deformity and could't obtain a high union rate due to distraction. Therefore, we recommend that adequate external support is considered to prevent distraction using the flexible I-M nail. Although we obtained a satisfactory union rate using by Seidel interlocked I-M nail, we must observe the distal spreading screw loosening during the follow up period. In bones with small diameter, sufficient reaming may be necessary, because the distal spreading screw can't spread well.

Recently, the frequency of meniscal injury of knee has been increasing due to increase of sports activities. It has been known that bucket handle tear is the most common type of the entire injuries of the meniscus. We found 127 cases of meniscal tears and experienced 42 cases of bucket handle tears in the arthroscopic findings from Jan. 1991 to April 1994 in our hospital. We analysed 31 cases which were followed up for at least 1 year. The purpose of this study is to analyse the locking history and frequency, to discuss the several types of bucket handle tear in arthroscopic view, to introduce three portal techniques using posteormedial or posterolateral portal to resect the meniscus, and to analyse our clinical results. So we concluded as follows. 1. Among the 31 cases, 23 cases(74%) had an episode of locking. 2. We found many different types of bucket handle tears in arthroscopic view and the most common type was complete tear in a classic type(11 cases). 3. We were able to resect the meniscal fragment very easily using posteromedial or posterolateral portal. 4. We obtained satisfactory results in 24 cases(77%).

The most commonly used graft source for anterior cruciate ligament reconstruction is the autogenous bone- patellar tendon-bone graft unit. Despite a good success record, intraoperative technical errors and postoperative complications have been known. Author analyzed intraoperative technical errors and postoperative complications, in 44 patients who were treated at the department of orthopaedic surgery, chosun university hospital from Jan. 1994 to Jun. 1996. The most common intraoperative technical errors was screw graft divergency in 5 cases. Other intraoperative technical errors were too anteriorly location of femoral tunnel in 1 case, too anteriorly location of tibial k femora) tunne.l both in 1 case, graft tunnel mismatching in 1 case, graft pullout in 1 case and partial destruction of posterior cortex of femoral tunnel in 1 case, fracture of the bone plug in 1 case. The most common postoperative complication was patellar tendinitis in 20 cases (45.5%). Other postoperative complications were anterior knee pain in 14 case. (31.8%), patellar crepitation in 12 cases (27.3%), quadriceps atrophy in 9 cases (20.5%), arthrofibrosis in 3 cases and graft failure in 2 cases. Author concluded the causes of intraoperative complications were technical errors, and anteriorly location of graft tunnel is most influenced factor to final fuctional results. To eliminate the postoperative complications, intraoperative technical errors should be avoided and also accelerated rehabilitation should be done.

Arthroscopic anterior cruciate ligament reconstruction with bone-patella tendon-bone has been commonly using for ACL insufficient patients. Bone-patellar tendon-bone graft is a strong intra-articular substitute, which allows, by means of its bony end, a rigid fixation with early bone to hone healing. As a counterpart, potentially serious cornplications & donor site morbidity has been reported, such as patella fracture & patella tendon avulsion, anterior knee pain, patella tendinitis, dcmor site pain and bone defect. We suppose tightly packing the donor site bony defect with hetrograft (Lubboc) may be also useful. So, we analyzed the morphological change in bony defect and donor site morbidity between the group of non-replaced bony defect and the group of replaced bony defect using by heterograft (Lubboc). We replaceJ hetrograft into the patellar side bony defect in 15 knees and left alone in l5 knees. The average follow up period was 17 months. The results werc as follows: 1. Nearly norma1 appearance on the bony defect showed at the long tenn follow up roentgenogram in the group of replaced hetrograft, but scalloping on the pateltar bomp defect was seen in non-replaced group. 2. Donor site morbidity (pain or patellai tendinitis) was developed 8 knees in the replaced group, and 7 knees in the non-rep)aced group. 3. We conclude that the filled in the bony defect hy hone graft (heterografl:) can not decrease the donor site morbidi ty.

Thirty-three cases of the fracture of the femur and tibia on the same limb were treated at the Orthopedic Department of the Chosun University Hospital during the period from January 1977 to December 1983. The following results were obtained. 1. The incidence of trauma was high in the young man, most frequent in the third decade (45.4%). 2. The most common cause of the fracture was traffic accident (81;8%). 3. The most common shape of the fracture was comminuted in both femur and tibia. 4. The common fracture site were middle one-third in both femur and tibia. 5. Eight patients were treated by conservative means on both femxr and tibia. The patients were treated by internal fixation on femur and by conservative means on tibia. Internal fixation was .done in ten patients on both femur and tibia. Two patients were treated by inteinal fixation on tibia and by conservative means on femur. Three patients were amputated. 6. Average healing time of fracture was 21 weeks in femur and 24.2 weeks in tibia. 7. Functional end results were assessed and rated with satisfactory results in rigid internal fixation of the femur and tibia.

The cases of 82 humeral shaft fractures were evaluated at the Department of Orthopedic Surgery, Chosun University Hospital, during the ten years period from January 1978 to December 1987 and the following results were obtained. 1. The most common type was transverse fracture (59.8%) and the most common site was middle one third (61.0%). 2. The average time of bone union were about 9.6 weeks in non-operative cases and 9 weeks in operative cases. 3. The radial nerve palsy was more common in transverse fracture of humerus at the middle one third level. 4. Among the 28 radial nerve palsy associated with humerus fracture, 19 cases were treated by conservatively, and 9 cases were treated by surigical exploration. 73.7% of conservatively treated cases and 77.0% of operatively treated cases regained most of the functional lost of the radial nerve.

Cubitus varus deformity is the most common angular deformity resulted by supracondylar fractures in children. Although, this deformity rarely limit elbow function, the correction is frequently requested due to cosmetic problem. The normal carrying angle can be restored by supracondylar osteotomy. Previous reports controversy over the cause of the deformity, the necessity and timing of operative correction, the operative technique itself, and the attendant risks. We performed 18 lateral closing wedge osteotomies with French technique(10 cases), and Sherman plate fixation(8 cases) by posterolateral approach from January 1978 to December 1988 at Chosun University Hospital. The results were as follows: 1. The most common cause of cubitus varus was suprcondylar fracture of the humerus(88.9%). 2. The results of supracondylar osteotomies were excellent is 8 cases(44.8%), good in 7 cases (38.9%), poor in 3 cases(16.7%). 3. The varus and rotational deformities were corrected by modified French method and Sherman plate fixation after lateral closing osteotomy. 4. In case of plate fixation, good results were obtained even older cases because of reducing time of extermal immobilization and promotion early joint exercise.

Kirschner-wires and pins are used for the intenal fixation of the acromioclavicular joint. Many surgeons are aware of the tendency of these appliances to migrate, however, few reports of this complication have appeared in literature. This report concerns two instances of migration K-wires from the acromioclavicular joint into the neck, The potential for K-wires to migrate must be recogniged, and more frequent postoperative radiographic studies performed after the insertion of such pins to permit earlier detection of bony resorption and migration. Thereby permitting earlier removal. In cases of young adult, the wires must be removed as soon as the desired theurapeutic results have been obtained.
