In our review of 36 hematogenous osteomyelitis nine cases were subacute form. Distal tibia was the most commonly involved location(four of nine patients). According to the modified Robert's classification cross-physeal lesions were the most common type(four of nine patients). In most of the cases the clinical findings and laboratory data were not much helpful for current diagnosis. Four patients had radiographic findings similar to those of tumors such as Ewing' s sarcoma, osteoid osteoma or bone cyst. Magnetic resonance imaging was useful in the identification of early lesions. In three patients Staphylococcus aureus was isolated by bacterial culture of biopsy specimen. In the remaining six patients diagnosis was made by histological evaluation. All patients except one were treated by curettage and antibiotics. In the other patient the disease showed a tendency of spontaneous healing without operative intervention and antibiotics. Cross-physeal lesion seemed to be a typical finding of the subacute osteomyelitis.

We describe an extra-articular triplane fracture of distal tibia in a twelve-year-old boy. This variant of the triplane fracture has been largely ignored in the literature. The clinical significance of recognizing this fracture is that, although it constitutes an epiphyseal fracture, it remains extra-articular. We treated this case by open reduction and internal fixation of both distal tibia and fibula. However, unlike the standard triplane fracture that exits through the tibiot alar joint, this variant may be treated acceptably with less that an anatomical reduction, therefore avoiding the need for surgical management.

Lichen aureus is a variant of pigmented purpuric lichenoid dermatitis. The skin lesions usually appear asymptomatic rusty, copper, or orange colored roundish lichenoid erythematous-purpuric papules and patches on the lower extremities. Histologically, the epidermis shows minimal changes, with a dense lymphohistiocytic infiltrate observed in the superficial derrnis, typically distributed in a band-like fashion. The typical lesion is a single patch localized on the lower extremity. We report a rare case of segmental lichen aureus localized on the right lower extremity.

The methods of treatment of spondylolisthesis range from posterior fusion to instrumentation, and circumferential fusion. Combined anterior and posterior fusion with instrumentation had been carried out in one or two stages and satisfactory results were obtained in nighteen cases with follow-up period of one year to four years at department of orthopedic surgery of Ewha Womans University Hospital from 1987 to 1991. The results were as follows: 1. Of 19 patients, 7 patients were male and 12 patients were famale. 2. The isthmic type was 12 cases (63.1%) and the 5th lumbar vertebral involvement is common (12 cases, 63.1%). 3. The operative treatment was as follows: Posterior fusion with instrumentation was 8 cases, and anterior fusion with instrumentation was 11 cases. 4. The combined anterior and posterior fusion with instrumentation had been carried out in one stage operation at 8 cases, and two stage operation was done at 11 cases. 5. The average operation time was 3.0 hrs in one stage operation, 3.1 hrs in two stage operation, and the average amount of blood loss was 22cc/Kg in one stage, 17cc/Kg in two stage. 6. The satisfactory results were obtained in 19 cases, but there was no specific difference between one stage and two stage operation.

Kyphotic deformity of thoracic or lumbar spine is generally developed as a consequence of Scheuerman's kyphosis, ankylosing spondylitis, congenital kyphosis, tuberculous kyphosis, spinal tumor, senile kyphosis, trauma and extensive laminectomy etc. The method of treatment is usually conservative. However, in severe kyphosis, gross abnormaility and neurologic complications, and the compression of cardiopulmonary system are resulted and then surgery may be indicated. Since the report of spinal osteotomy by Smith-Peterson, several treatment options have been reported. Despite improved techniques for treating spinal kyphotic deformities, correction of severe and acutely angled deformities are less effective and resulting many complications. We propose the use of a new method of posterior closing spinal osteotomy for the treatment of severe and acutely angled kyphotic deformity to minimize the complications and for effective correction. We report the technique and results of this method in two cases of tuberculous kyphosis and a case of ankylosing spondylitis.

Fifty two cases of displacecd supracondylar fractures were divided into three groups according to the methods of fracture stabilization. Cast immobilizations without pin fixation were included to the group 1 (12 cases), fixation with lateral pins to the group 2 (22 cases), and lateral and medial cross pins to the group 3 (18 cases). In each group we attempted a radiological analysis for the stabilization failure through measurements of the horizontal rotation and the mediolateral tilting in their preoperative, postoperative and follow-up X-rays. Stabilization failure during the follow-up period was presumpted to be present in those cases that show (1) a development or increase of the horizontal rotation in follow-up lateral X-ray, and (2) accompanied change in Baumann's angle of more than 5 degrees. The failed stabilizations were in three cases (25%) in the group 1. In the group 2 the horizontal rotations after initial fixation were developed in four fractures. However, only two (9%) of the four cases accompanied significant changes in the Baumann's angle. Loss of the initial fixation in the cross pin group was found in one case. These results demonstrate that the cross pin fixation is the most stable form. Fixation in only lateral side sometimes shows rotational instability, but this method seems to be still useful because singificant coronal tilting develops in only a few occasions of those with horizontal rotation.

From retrospective review of 111 tibial fractures treated by interlocking intramedullary nailing, 38 operative errors in 28 cases(25%) were included in this study. The errors were classified into two categories. The first category included eighteen errors that related to fracture reduction; nine angular malalignments, four failures in closed nailing to open the fracture site, two peroneal nerve palsies, two shortenings of tibial length(more than 1cm), and one rotational malalignment. The second category comprised twenty errors that related to the nailing itself; eight protrusions of proximal nail tip, five overdistractions of fracture gap (more than 3mm), four additional fragmentations, two mistakes in interlocking screw insertion, and one ankle joint injury by the distal nail tip. Functional results of those 28 cases at the last follow-up(average, 17.5 months; range, 9 to 29 months) were excellent or good in only 60.8 per cent, while the control group treated by adequate operative technique showed excellent or good results in 92.8 per cent.

In the review of a series of 71 clavicle shaft fracture that were treated with open reduction and internal fixation, we tried a direct comparison between two fixation modes, that is, the fixation with plate and screws (54 cases) and the intramedullary nailing with Knowles pin (17 cases). The average time to healing was not significantly different between the two group; 10.8 weeks after the plating and 11.7 weeks with Knowles pinning. The rate of successful healing within four months after the surgery were also high in both groups: one delayed union and one nonunion in the plate group, and one delayed union in the Knowles pin group. There was one loosening in the Knowles pin group, which needed reoperation. Intramedullary fixation has several advantages compared with fixation with a plate and screws. It can be performed through a shorter incision: less dissection of soft tissue is needed: and, after healing, the pin is easily removed through a small incision under local anesthesia.
