ABSTRACT
One of the most frequently used flaps for coverage of sacral skin and soft-tissue defects is the gluteus maximus musculocutaneous flap. These authors encountered two cases of sacral pressure sore, for which reconstructive surgery was performed, using the hatchet-shaped gluteus maximus musculocutaneous flap - a modified flap type. We report on our experience in treatment of these two cases, with an excellent outcome.

Traumatic dislocation of the radial head without fracture of the olecranon is very rare, especially in adults. We experienced a case of irreducible radial head dislocation with fracture without involvement of ulna. Open reduction and internal fixation was performed. During surgery, brachialis was interposed between capitellum and radial head, and also interposed between the fragments at the fracture site of the radial head. At 12 months after operation, the radial head was well reduced with normal rotation.

An osteoid osteoma is a benign bone tumor. It is most commonly found in the femur and tibia but only 5% to 15% occurs in hand. Osteoid osteoma of carpal bone has vague nature of symptoms including spontaneous dull aching causing delayed diagnosis and the late treatment. We had a patient with an osteoid osteoma of the capitate bone presenting with tenosynovitis. We present clinical and radiological findings including magnetic resonance imaging, surgical result, and a review of the current literature.

Chondromyxoid fibroma is an uncommon benign cartilaginous tumor of the bone. It occurs most frequently in the metaphysis of long tubular bones, and an epiphyseal location is exceedingly rare. We present here an unusual case of a chondromyxoid fibroma that occurred in the epiphysis of the proximal tibia with an open growth plate. MR imaging findings of this tumor, which has, to the best of our knowledge, never been described in an epiphyseal location, makes the present case unique.

PURPOSE: This article presents a retrospective study of treatment modality for children's diaphyseal forearm fractures. MATERIALS AND METHODS: A total 148 forearm fractures (October. 1997-October. 2001) were examined, of which 19 required operation, a teenager whose growth plate had closed was excluded from the study. 17 patients required intramedullary K-wire fixation, 2 patients required open reduction and plate fixation. Time to radiologic union, complications at the last follow up were evaluated. RESULTS: In 17 intramedullary K-wire fixation patients, the average time to union was 6 weeks and complications including 1 ulnar shortening, 1 pin infection, 1 osteomyelitis, which developed due to a patient's mistake. In 2 plating patients, average union time was 6 weeks with no complications. CONCLUSION: We think that the treatment method of pediatric forearm fracture should be decided upon based on the fracture site and type of fracture. Intramedullary K-wiring for diaphyseal forearm fracture is an effective method and we recommend that the wire is inserted across the physis in cases of diaphyseal fractures of the forearm bone close to the metaphysis. If the diaphyseal forearm fracture is refracture or a bony gap is shown at the fracture site, open reduction and plate fixation is needed. If reduction and fixation of the bone alone in a diaphyseal fracture of both forearm bones restores the stability of other fracture, fixation of the other bone can be avoided.

PURPOSE: Bone bruises of patients with acute traumatic knee injuries, that are not found on simple radiograph, can be found on magnetic resonance imaging (MRI). The purpose of this study is to evaluate the frequency and locations of bone bruises on MRI in acute traumatic anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) injury. MATERIALS AND METHODS: 25 and 19 MRls, in which acute traumatic ACL and PCL injury was pre sent and there was no abnormality in simple radiograph, were reviewed. MRI was taken within 51 days of injury. A bone bruise was determined as a geographic and nonlinear area of signal loss on T1 images and increased signal intensity on T2 images involving the subcortical bone. RESULTS: In 16 patients with bone bruises and acute ACL injury, bone bruises were found in the lateral compartment of the knee in 15 (93.8%) patients. The most common area was the lateral tibial plateau (11 cases, 68.8%) and the second was lateral femoral condyle (9 cases, 56.3%). In 5 patients with bone bruises and acute PCL injury, bone bruises were found in the lateral compartment of the knee in all 5 (100%) patients. The most common area was lateral tibial plateau (4 cases, 80%) and the second was lateral femoral condyle (2 cases, 40%). CONCLUSIONS: In patients with acute traumatic ACL or PCL injuries the bone bruises are often found on the lateral compartment of the knee, especially lateral tibial plateau and lateral femoral condyle on MRI.

We reviewed 14 children with unilateral fractures of femoral shaft who had an angular deformity after union of 10° to 25°. At an average follow-up of 32 months(15 to 65), we measured remodelling of the proximal physis, the distal physis and the femoral shaft. The average correction was 83% of the initial deformity and there was no relation between the remodelling rate and degrees of malunion. Of the correction of angulation, only 27% had occurred at the fracture site and 73% at physis. The ability of physis to remodel better than that of fracture site. In children under 13 years of age, malunion as much as 25° in flexion deformity will remodel enough to get normal alignment of the joint surfaces.

Fractures of the shaft of the radius and ulna occur commonly in children and are usually treated by closed reduction and plaster cast immobilization. Anatomic reduction is seldom necessary because of the remodelling potential in the child under 10 years of age, whereas the bones of children older than 10 years of age have less capacity to remodel and the diaphyseal fracture is unstable. In case of either unacceptable reduction or unstable fractures in adolescent patients, an operative treatment is required. In five children older than 12 years of age for whom conservative treatment had hailed, we treated a closed intramedullary nailing using a distal radial and proximal ulnar approach, and followed up for 1 year or more. All fractures healed within 6 weeks. No nonunion, cross-union or refrature occured. Another advantages of this method are negliable cosmestic defect and easy removal of the internal fixation device under local anesthesia. We think that closed intramedullary nailing with rush pin is a safe and reliable method to treat unstable forearm fracture in children older than 12 years of age.

The hook-nail deformity after finger tip amputation is very common problem. This usually occurs after loss of part of the distal pulp, phalanx, and nail bed. This deformity for some patients is a trivial lesion and may be ignored, but it may be of great cosmetic significance or disabling with regard to certain occupations to the others. To correct the deformity, it is necessary to release volarly displaced nailbed, return it to its normal position, and provide adequate support to maintain correction by a carefully planned "antenna" procedure. Deformed nail is removed, tethered pulp is freed from distal phalanx, and then full thickness of the nail bed is elevated and splinted with multiple small Kirschner wires in a straight position like antennae. The coverage of defect created is done by cross finger flap. The knowledge of anatomy and physiology of nail and sorrunding structures is important to obtain good results and reduce secondary deformities. Two cases of antenna procedures for the hook nail deformily is reported with good results.

We recently treated an infant with abnormal calcification in the soft tissues of the wrist and hand caused by an intravenous injection of calcium gluconate for treatment of neonatal hypocalcemia. The cause of the soft tissue calcifications was quite puzzling, if the incident of calcium gluconate extravasation had been overlooked, because the lesions mimicked for cellulitis or abscesses and treated as such. All radiographic evidence of calcification gradually resorbed by conservative management.

The hamate fracture is very rare condition. The mechanism of fracture may be attributed to direct trauma by rolling down. We have experienced a case of fracture of the body of the hamate bone. It was treated by conservative method. The result was satisfactory with conservative treatment without traumatic arthritis, nonunion, ulnar nerve palsy, flexor digitorum profundus tendinitis & limitation of motion. A case of fracture of the body of the hamate bone is reported with brief review of literature.

The incidences of posttraumatic avascular necrosis of the femoral head were variably reported. In 1980, Calandruccio reported its incidence of 14% in nondisplaced femoral neck fracture and 50% in displaced ones. In general, the prophylactic methods, such as core decompression, bone graft and trochanteric osteotomy were recommended for the treatment of early stages of femoral head avascular necrosis(Ficat-Arlet stage 1 or 2), while the primary replacement surgery for the advanced ones (Ficat-Arlet stage 3 or 4). One of our authors(Y.K. Chung) has performed five cases of corticocancellous bone grafts using combined autogenous free fibular graft and iliac cancellous bone graft, for the post-traumatic femoral head AVN from January 1985 to December 1989 at our hospital, and the following results are obtained: 1. Among the forty nine displaced adult femoral neck fractures, there were five eases of avascular necrosis(10. 2%). 2. There were three male patients and two female ones, and the average age of injury was 48 years old(30 to 57). 3. According to the type of fractures, there were four cases of subcapital fracture and one of transcervical fracture. All of the patients were performed closed reduction and internal fixation with compression hip screw system, including additional Knowles pinning in two cases. 4. Histological study with the excised femoral head, showed that there was no bony union between the grafted cancellous bone and the necrotic head, and the grafted bone has been changed to amorphous necrotic tissue. However, we found a solid consolidation of the grafted bone and the femoral neck portion.

The use of the interlocking intramedullary nails expand the possibilities for treatment of femoral shaft fractures, as illustrated by consistent and satisfactory clinical results. However, the technique is relatively complex compared to conventional nails and frequently poses technical problems. A retrospective review was undertaken of twenty-eight patients with femoral shaft fractures which had technical problems after undergoing the closed reduction and internal fixation with interlocking intramedullary nail procedure. We studied the types of the problems. Their causes, the frequency of problems with various kinds of nails, and discussed solutions of the problems. There were 21 additional comminutions and intraop erative splinterings, 8 angular deformities, 3 malpositioned nails, 3 loosened distal locked screws, 2 brocken drill bits, and 1 femoral neck fracture. Bone-union was attained in all cases (28 patients), but the period of treatment to attain bone-union was protracted to an average of 6.8 (5-12) months. In 3 cases, the knee joint range of motion was of limited flexion, 70 to 90 degrees, but in all other cases full range of motion was realized. 7 cases required 2 or more operations. The hospitalization period was for an average of 3.6 months. In conclusion, the importance of careful preoperative planning and experienced surgical technique cannot be overemphasized because we could see no significant difference in the occurence of technical problems in several kinds of the nail.
