Abstract PDF: OBJECTIVES
We have studied the effects of Yuhan bone connecting powder on the healing process of the frauture at the osteotomized bones in rat, using bone densitometer, X-ray and morphological studies after administration of Yuhan bone connecting powder which has been reported in China as enhancing the processes of the fracture healing.
MATERIALS AND METHODS
90 Sprague-Dawley male rats were divided into the rib and tibia osteotomy groups. Each group was subdivided into the control, low dosage and high dosage groups. Rib and tibia were osteotomized under the general anesthesia with ketamin. From the next day after operation, Yuhan bone connecting powder diluted with distilled water was administrated to low(0.68g/kg) and high(1.36g/kg) dosage groups per se. Same amount of the distilled water was used to the control group. 1.5cm long rib including the osteotomy site and whole tibia were excised. Bone densitometer using dual energy X-ray absorptiometry, radiological and morphological studies with HE stain and alcian blue(pH 2.5)-PAS stain were performed.
RESULTS
BMD showed statistically significant difference between control group, low dose group and high dose group at 2weeks after treatment(p=0.035), but did not show such a good result at 1week(p=ns) and 4weeks(p=0.091) after treatment. Radiologically, after treatment for 2 weeks, the low and high dose groups showed more active callus formation than control group. Morphologically, dilated numerous blood vessels adjacent the bony trabeculae and well developed cartilagenous callus were observed in the experimental group at the 1st week. At the 2nd week, many newly formed bony trabeculae were formed from the cartilagenous callus, and at the 4th week relatively thick compact bone and bony trabeculae were connecting the both osteotomy ends.
CONCLUSION
BMD at the osteotomy site seemed to be increased after administration with Yuhan bone connecting powder to rats, and this finding was supported radiologically at 2weeks after treatment. Morphologically, at the early stage of the fracture healing, numerous dilated blood vessels were distributed and many bony trabeculae were formed from the cartilagenous callus. At the remodelling stage relatively thick compact bone was connecting the both ends of the osteotomy site. So it is suggested that Yuhan bone connecting powder would induce enhancing the healing process of the osteotomized bone in rat through active vascularization, mineralization of the cartilage matrix, endochondral ossification and remodelling.

A Clinical Study of the Comminuted Fracture of Patella: Il Yong Choi, Sung Joon Kim, Tai Seung Kim, In Mool Lee; J Korean Soc Fract 1996;9(3):631-639. Published online July 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.3.631

Abstract PDF: Recently the fracture of patella especially comminuted fracture has increasing tendency due to frequent traffic accident. Because of the patella is an important functional component of the knee extensor mechanism, and proximal three-quarters of the posterior surface of the patella are covered with articular cartilage. accurate reduction and rigid fixation are important in treatment of the comminuted fracture of the patella. Some fractures were treated successfully by immobilization in a cylinder or an above-knee cast, but most patellar fractures should be treated surgically. Various techniques of internal fixation have been recommended for comminuted fractures of the patella, but best way should be selected out of various methiods case by case. In this series, 48 comminuted patella fractures between January, 1990 and April, 1995 have been reviewed at least 9 months after injury and obtained following results. 1. Peak age was third to fifth decade and predominant in men. 2. The major causes of the comminuted patella fractures were traffic accident in over-all, and slip down in sixth and seventh decades. 3. Most fractures were accompainied by other fractures. 4. fourteen patients had postoperative complications, six had patellofemoral osteoarthritis, three metal failure, two loss of reduction, two superficial infections and one malunion. 5. In long-term follow up, the factors that related to the range of motion of the affected knee were though to not the operative method but initial severity of the comminution and accampanied injury.

Clinical Application of Gamma Nail: Il Yong Choi, Kwang Hyun Lee, Chung Kyu Choi; J Korean Soc Fract 1996;9(2):489-495. Published online April 30, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.2.489

Abstract PDF: The Gamma nail combining the advantages of a sliding lag screw and the intramedullary femoral fixation is a advance in the treatment of trochanteric fractures. The Gamma nail is a new intramedullary device which has been applied in treatment of the trochanteric fractures with the benefits of closed technique such as low blood loss, low risk of infection, short operative time, short bone union period and early weight bearing and with the biomechanical advantages such as short lever arm and decreased bending moment. The implant can be used by the method of static or dynamic. Intraoperative compression of the fracture segments can be achieved by acting on the sliding lag screw and further compression is given by weight bearing. We studied 31 cases of patients who had the trochanteric fractures and treated opratively with Camma nail. The intertrochanteric fracture was 25 cases and subtrochanteric fracture was 6 cases. Intraoperative complication was encountered failure of distal locking in 1 case. Postoperative complications were encounted superior cutting-out in 3 cases. As results of postoperative ambulation, 4 cases were death, 4 cases were bedridden state, 4 cases were ambulation state within house, 19 cases were social activity respectively.

Abstract PDF: We reviewed 55 cases of open fracture of the forearm bones had been treated by conservative treatment or open reduction and intramedullary nailing or internal fixation with dynamic compression plate and analyzed the results by wound management and methods of treatment.The results were obtained as follows ;1. In the type I,II and type III-A open fractures, primary closure of the wound was reliable method of treatment. 2. The non-union rate was 44% in the positive culture test and 14.8% in the negative culture test. 3. Immediate internal fixation with dynamic compression plate was reliable method in the treatment of the type I, II open fractures.

Yvascular Injuries Associated with Fracture and Dislocastion of the Knee: Sung Joon Kim, Il Yong Choi, Jae Lim Cho, Soo Tai Chung; J Korean Soc Fract 1990;3(1):40-45. Published online May 31, 1990; DOI: https://doi.org/10.12671/jksf.1990.3.1.40

Abstract PDF: Injury of the popliteal artery associated with fracture and dislocastion of the knee is uncommon, But, when the fracture and dislocation of the knee occurs, it frequently associated with vascular injuries, and vascular injury can be a very serious one because of ischemia that necessitates amputation. Sixteen vascular injuries combined by fractures and dislocation of the knee between March, 1985 and February, 1989 have been reviewed and the results are as follows. 1. There were 11 cases of proximal tibial fracture, 2 cases of distal femoral fracture and 3 cases of knee dislocation. 2. The site of injury which is proximal to insertion of the soleus muscle were 15 cases. 3. There were contusion in 11 cases, rupture in 4 cases and laceration in 1 case. 4. One of the 2 cases(50%) that were treated within 12 hours after injury survived, while two to 10 cases(20%) that were treated after 24 hours following injury survived. 5. The open reduction and internal fixation was done in 5 cases, the skeletal traction in 1 case, and cast immobilization in 10 cases. 6. Finally, the B-K amputation was done in 4 cases, A-K amputation in 6 cases, knee disarticulation in 2 cases.

Abstract PDF

Injuries about the ankle joint resulted in not only fractures of the bone but also ruture of the ligamentous and soft tissue structures and it is important that accurate reduction and rigid internal fixation of fracture as well as repair of ruptured ligament should be performed. The author analyzed 35 cases of the trimalleolar fractures of the ankle which were admitted and treated in Department of Orthopaedic Surgery, Hanyang University Hospital from january 1984 to December 1988. The results obtained from this study were as follows; 1. Among the 35 cases, male was 25 cases(71.4%), female was 10 cases(28.6%), and average age was 37.43 years. 2. The main cause of the fracture was 18 cases of slip down(51.43%), and other causes were traffic accident(22.86%), fall from a height(17.14%), sports injury(5.71%), and other injuries(2.86%). 3. Open fractures were 2 cases(5.7%), and closed fractures 33 cases(94.3%). 4. According to the classification of Lauge-Hansen, the pronation-external rotation type was 22 cases(62.86%), and the supination-external rotation type, 13 cases(37.14%). 5. Open reduction was performed in 25 cases(71.43%), and closed reduction 10 cases(28.57%). 6. The average period of the cast immobilization after open reduction was 10.7 weeks, and 8. Fractures with a posterior marginal fragment invoving 25 percent of more of the tibial articular surface, open reduction was recommended.
