Abstract PDF: A fracture-separation of the distal humeral epiphysis in children is an extremely rare injury and presents problems in diagnosis, radiographic interpretation and management. From June 1992 to December 1996, Authors experienced the 5 cases of Salter - Harris type II injury of the distal humeral epiphysis at Department of Orthopedic Surgery, Pusan Maryknoll General Hospital. The patient were followed up from one year nine months to three years four months. The two cases were treated by closed reduction and percutaneous K-wire fixation and the three cases by open reduction and internal fixation with K-wires. There were 4 cases of complication seldom reported following fracture-separation of the distal humeral epiphysis. This complications consist of 4 dissolutions of trochlea, which is one, frank avascular necrosis of trochlea. In 3 cases with open reduction developed the cubitus varus & dissolution of trochlea. We speculate that this complications results from avascular necrosis of distal end of humerus. Attention to change of carrying angle and radiographic change of distal humeral end are important in detection of complication & evaluation of etiology of dissolution of distal humeral end.

Fracture of Olecranon Treated by K-wire and Tension Band Wiring Technique in Adults: Hak Yeong Jeong, Seung Wook Yang, Jae Woong Shim, Beyong Seon Kong; J Korean Soc Fract 1997;10(3):651-657. Published online July 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.3.651

Abstract PDF: Displaced fractures of olecranon in adults require operative treatment. The goal of treatment is to rigidly fix the fracture fragment, to anatomically restore the joint surface and to allow range of motioin early. Authors treated fractures of olecranon by open reduction and internal fixation using K-wire and tension band wiring technique in 38 adult patients from April 1989 to October 1995 at the Department of Orthopedic Surgery, Maryknoll Hospital. This article documents the study of relationship between the treatment result and involvement of articular surface, articular step-off and gap of articular surface. The results were as follows ; 1. The clinical results were good or fair in 31 cases(82%) according to the criteria by Helm et al. 2. Involvement of articular surface, step-off and gap of articular surface affected the results. 3. The clinical results were satisfactory in patients with postoperative step-off less than 2mm and postoperative gap of articular surface less than 2mm. 4. The clinical results were satisfactory in patients with articular involvement less than 60%.

The Treatment of Infected Fracture of Long Bones: Hak Yeong Jeong, Seung Wook Yang, Young Cheol Shin, Jae Woong Shim; J Korean Soc Fract 1995;8(3):678-687. Published online July 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.3.678

Abstract PDF: The increase in incidence and severity of open injury to bone and surrounding soft tisseues from vehicular and industrial accidents, and the aggressive surgical approach of open reduction and internal fixation of closed fractures contribute to a definite rise in acute wound infection in fracture management. The main objectives are twofold in the treatment of infected fractures, the first to diagnose infection early and the second to treat it effectively and to prevent it from spreading into bone. To solve these problems, we used some principles of treatment, those are meticulous debridement of infected tissue, management of soft tissue and bony defect and maintenance of fracture stability. From Jan. 1988 to Dec. 1993, we treated 23 infected fractures of long bone and the result were as follows. 1. The infected fractures were femur in 9 and tibia in 14 cases. 2. There were 14 open fractures and 9 closed fractures. 3. In closed fracture, the first infection sign was developed average 7.8 days after open reduction, and average 9 days after trauma in open fracture. 4. The most common causative organism was staphylococcus aureus. 5. Infection was controlled from 3 months to a year and 8 months. 6. The number of soft tissue and bone debridement was one to four times. 7. Bony union was achieved from 6 months to 2 years in tibia and 6 months to 2 years and 1 month in femur.
