39 patients with tibial shaft fracture had treated by open reduction and internal fixation with AO DCP and screws applying on the medial surface of the tibia, at the Department of Orthopedic Surgery, Ulsan Dongkang Hospital, from January, 1983 to December, 1985. A clinical study was done on all the 39 cases with the follow-up check over 1 year. In general, because the lateral surface of the tibia is well covered by rich soft tissue, it is popularized to apply the plate on the lateral aspect of the tibia. In our department, we applied the plate on the medial aspect of the tibia, which resulted in mimi-zing soft tissue injuries and, by inserting the screws perpendicular to the surface of the bone, increased stability of the fixation; and therefore resulted in relatively short operation time, relatively low incidences of infection and non-union; but there had been some drawbacks such as focal skin necrosis, hematoma, adhesion after fixatives removal, and cosmetic disfiguring. But there were no problems during the follow up periods. So, this is a recommandable procedure of internal fixation with the plate for the tibial shaft fractures.

The “delta phalanx”, first named by BlundeII Jones in 1964, is a triangular(“delta-shaped”) or trapezoidal phalanx with C-shaped epiphyseal plate causing progressive angular deformity of the digit with growth. Neither splinting nor physical therapy is effective in improving the condition. Surgical correction is indicated and several methods of correction have been reported. Authors have experienced a rare case of “delta phalanx” occuring in the proximal phalanx of the syndactylous digit.

Fourty one cases of open fractures of tibial shaft complicated with varying degrees of soft tissue injuries were trested by one-plane unilateral external fixation with AO fixator. In seventeen csses among them, interfragmental lag screw fixation was applied in addition, for more rigidity and stability of the fixation. All of thern were followed up at least for one year and we obtained the following results. 1. Rigid stable external fixation provided by additional minimum internal fixation may not increase the rate of infection but rather enhance prompt primary bone healing. 2. One-plane unilatersl external fixation may facilitate good access to the wound for subsepuent reconstructive procedures, and enhance pain-free early full range of joint motion, thus promote early bone union. 3. Comparing with bilsteral fixation, there wss almost no difference in the union time of the fracture even with one-plsne unilatersl fixation.

The traditional treatment for the femoral shaft fractures in children is closed reduction by continuous traction, usually for 2–3 weeks, until the fracture has achieved partial stability, followed by spica cast immobilization. Fifty three cases, from 3 to 10 years of age, has been treated with closed reduction and immediate application of hip spica csst; all of them were closed fractures of femoral shaft and were not associated with head, abdominal, or vascular injuries. Any angulations in excess of acceptable ranges were corrected with wedging the cast; any overridings in excess of acceptable ranges were corrected by skeletal traction for 1 week, followed by incorporation of the pin to the cast. The resultant overriding and angulation of fragments were within acceptable ranges, and complications were not significant.This method of treatment not only is likely easy in nursing care and comfortsble to the patients but also has some advantages of short stay in the hospital, better utilization of hospital beds, and costsaving. This immediate hip spica cast immobilization seems to be a good method of treatment for the femoral shaft fracture in children.

The goals of orthopaedic management of pelvic ring injuries are to achieve anatomical reduction and secure fixation of fragment and mobilize the patient as early as possible. Previously, pelvic ring injuries have been treated by a wide variety of conservative methods. Their application, however, necessitated a prolonged period of recumbency with associated likelyhood for many complications and did not facilitate accurate reduction and stabilization of most types, resulting in pelvic deformity, non-union and late sacroiliac joint instability. During the past decade, experience with techniques of external and internal fixation of the pelvis has grown and the goals of the methods include provision for sufficient pelvic stability in satisfactory position so that immediate postoperative bed-to-chair transfers can be undertaken and complications due to prolonged recumbency and pelvic deformity can be markedly reduced. We reviewed 47 cases of unstable pelvic ring injuries treated at the depatment of orthopaedic surgery, Dongkang Hospital from January 1984 to December 1987, and the results were as follows ;1. The highest incidence was in the 4th decade and sex ratio between male and female was 1.6:1 2. The most common cause of injury was traffic accident (68.2%) followed by falling down accident (19%) 3. Associated injuries occurred in 28 cases (60%): injuries of the extremities were most common (30%) followed by head injury (13%) and genitourinary tract injury (11%). 4. According to classification of Pennal et al, lateral compression injury was most common (51.1%). Bucholz Group II injury was 57% of all and Group III, 43%. 5. Operative methods, with which 21 cases were treated, were anterior external fixation with AO apparatus or symphyseal plating in Bucholz Group II injuries ; and external fixation, internal fixation (anterior and/or posterior) or both, in Group III injuries. 6. Advantages of operative treatment of unstable pelvic ring disruptions were, by giving stability, early mobilization; easy care of associated injuries, open wounds and nursing; prevention of possible complications of prolonged recumbent position; rapid reduction of pain; and prevention of late complications such as lumbosacral or pelvic pain and gait disturbance.

The author reviewed 148 cases of phalangeal and metacarpal fractures of the hand, excluding distal phalangeal and carpal bones, in 75 patients treated at the Department of Orthopaedic Surgery, Dong-Kang Hospital, from January, 1984 to December, 1987. We obtained the following results ; 1. Better results were obtained in younger patients, transveres or spiral fractures, and cases immobilized in MP joint flexion. 2. Factors that led to worse results included older age, comminuted fracture, wide displacement, intra articular fracture, associated tendon injury, intraarticular pin placement. 3.In case of K-wire fixation, dorsal placement of the wire revealed better result than volar one.

The patella is an important component of the extensor mechanism of the knee. It serves to increase the mechanical advantage of the quadriceps muscle by increasing its lever arm. Therefore, if possible, when the patella is fractured, it should be repaired rather than excised. Present surgical techniques for the patellar fractures utilizes principles of anatomic reduction with repair of any associated retinacular tears, rigid internal fixation, and early institution of joint motion exercises. To compare the efficacies of the commonly used wiring techniques, we performed tension tests with transversely bisected patellar models fixed with circumferential wiring, Magnuson wiring, modified tension band wiring and modified tension band wiring combined with circumferential wiring. Also, we reviewed 66 surgically treated patellar fractures from Jan. 1984 to Dec. 1988, when we had given every effort to preserve the patella using modified tension band wiring or modified tension band wiring combined with circumferential wiring. l. According to the results of the tension tests, modified tension band wiring and Magnuson wiring were more rigid than circumferential wiring and the rigidity of modified tension band wiring was much increased when combined with circumferential wiring. 2. Of the 66 cases, 46 cases were treated with modified tension band wiring combined with circumferential wiring, and the remainder were treated with modified tension band wiring. 3. On the whole, good and excellent results were achieved in 87.9% (58 cases). Unsatisfactory results were obtained in 15.0% of cases treated with modified tension band wiring and in 10.9% of cases treated with modified tension band wiring combined with circumferential wiring. 4. Most of the unsatisfactory cases were so severely comminuted that could not be achieved anatomic reduction, rigid internal fixation and early joint motion exercises.

Carpometacarpal and metacarpophalangeal joints of the thumb exhibit relatively wide range of motion, which may act as a shock absorber. So dislocation of these joints are relatively rare. Furthermore, a complete dislocation of the thumb metacarpal by simultaneous dislocation of carpometacarpal and metacarpophalangeal joints is a very rare injury, and only a few cases were reported in the English literatures. The authors will present a case of a complete dislocation of the thumb metacarpal in a 31 years old female.

In the assessment of thoracolumbar fractures, computed tomography (CT) is superior to other imaging modalities especially when a more definitive assessment of the posterior elements of the spine or the neural canal is desired. We evaluated 55 patients with acute thoracolumbar burst fractures, and correlated the amount of neural canal impingement (NCI), demonstrated on computed tomographic scans, with each patients neurologic status, level of injury and extent of recovery when neural deficit was present. The results were as follows ; l. Average NCI was significantly higher in cases with neurologic deficits (57.3%) than in cases with no deficit (29.8%). But the range of NCI was much overlapped between the two groups (32-100% with deficits vs. 8-69% with no deficit). 2. In cases with neurologic deficits, average NCI was significantly higher in lumbar spine (75.0%, range; 61-100%) than in thoracolumbar spine (49.2%, range; 32-87%). 3. There was no neurologic deficit in cases with NCI less than 30% in thoracolumbar spine and less than 60% in lumbar spine. 4. In thoracolumbar spine, there was more significant relationship between NCI and patient's neurologic status in T12 than in Ll. 5. The NCI did not directly correlate with the extent of recovery of neurologic deficits when present.

Fractures of the tibial plateau involve a major weight-bearing joint, Thus, to achieve good joint function one must strive to achieve joint congruity, axial alignment, stability, and a satisfactory range of motion. Present operative treatment of tibial plateau fractures utilizes the principles of anatomical reduction, elevation of the plateau en masse, bone grafting of the defect in the metaphysis, stable internal fixation and early joint motion. Authors reviewed the 45 tibial plateau fractures operatively treated at Dong-Kang Hospital from Jan. 1983 to Dec. 1988 and analyzed the possible factors that could influence the results. Factors that may adversely affect the results were 1) old female. 2) Hohl Type VI, 3) delayed operation, 4) inadequate reduction, 5) no bone graft, 6) meniscectomy, 7) cruciate ligament injury, and 8) delayed exercise.
