Abstract PDF: PURPOSE
To evaluate the result of modified Bosworth method augmented with Mersilene tape(MBM) compared with modified Bosworth method(MB).
MATERIALS AND METHODS
Thirty two acromiclavicular dislocation wrer treated with MB(15cares) or MBM(17 cases) and the mean follow up period was 26 months(12-43 months). We assessed the radiological and clinical evaluation(X-Ray & Weitzman Criteria) and complications.
RESULTS
Twenty nine cases(91%)(MB 13, MBM 16) were "excellent" or "good" according to the Weitzman criteria. At last follow-up, mean difference of the coracocalvialar distance between the normal and the injured site were 1.9mm(MB) and 1.6mm(MBM) and two ceses were developed the arthritis, and then performed the distal clavicle resection.
CONCLUSION
Modified Bosworth method augmented with Mersilene tape is a good option for acromioclavicular dislocation in stabilizing the joint, even if the screw loosening occurs with early postoperative ROM.

A STUDY OF ANATOMICAL CONFIGURATION OF LATERAL TIBIAL CONDYLE USING MR AXIAL IMAGE: Sung Do Cho, Yong Sun Cho, Bum Soo Kim, Tae Woo Park, So Gu Lew, Su Young Jung; J Korean Soc Fract 2001;14(3):398-403. Published online July 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.3.398

Abstract PDF: PURPOSE
To evaluate the anatomical configuration of the lateral tibial condyle using the MR axial images and to present the proper configuration of the head of the buttress plate that fit the lateral tibial condyle of Korean MATERIALS AND METHODS: With 110 MR axial images of the knee joint of male and female, we calculate the ratio of the maximal height of the arc of the l ateral tibial condyle to the length of the line between the end point of the arc of the lateral tibial condyle(the ratio of convexity) and the angle of the peak point of arc of the lateral tibial condyle(the angle of convexity), the absolute value of the difference of the angle of the end point of the arc(the value of symmetry) of that. then we evaluate the head of 3 the buttress plates with same methods and then compare with the result of the lateral tibial condyle.
RESULTS
The ratio and angle of convexity of Korean were average 0.216/49.04(total), 0.203/49.35(male), 0.235/50.36(female), and the value of symmetry were average 5.68(total), 5.76(male), 5.56(female). the ratio and angle of convexity of the head of buttress plate were average 0.177/43.21(EGIRE), 0.114/25(AO), 0.101/23.83(Solco) and the value of the symmetry were 1.643(EGIRE), 0.75(AO), 1.5(Solco). the ratio of convexity was correlated with age, height, and weight but angle of convexity was not correlated with weight.
CONCLUSION
The anatomical configuration of the lateral tibial condyle of Korean did not fit that of the head of the buttress plates and it would be necessary to make a new plate that fit the lateral tibial condyle for Korean.

Comparison of the results between reamed and unreamed femoral nailing: Bum Soo Kim, Sung Do Cho, Yong Sun Cho, Tae Woo Park, Sogu Lew, Hyung Jin Cho, Soo Hyun Cho; J Korean Soc Fract 2001;14(2):208-213. Published online April 30, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.2.208

Abstract PDF: PURPOSE
To evaluate the effectiveness between reamed and unreamed nailing in the treatment of femoral shaft fracture.
MATERIALS AND METHODS
Among the patients of femoral shaft fracture who were treated with reamed and unreamed nail, we reviewed 49 patients whose follow-up was possible for more than 1 year. The patients were divided into two groups: the reamed and the unreamed group. We reviewed union time, nonunion rate, complication and operation time and compared the effectiveness.
RESULTS
The average union time was 30.6 weeks in unreamed group and 27.8 weeks in reamed group, which was not different statistically. There were 5 cases of nonunion in 22 unreamed cases and 3 cases in 27 reamed cases, which meant no statistical difference. There was no significant difference of complications between the two groups. The mean operation time was 141 minutes in reamed group and 110 minutes in unreamed group, which meant statistical difference.
CONCLUSION
There was no significant difference in union time, nonunion rate and comlication between reamed and unremed group. The operation time was shorter in unreamed group, so unreamed nailing can be preferred in the treatment of multiply injured patient.

Treatment of the Open Tibial Fractures with Unreamed AO Intramedullary Nail: Bum Soo Kim, Sung Do Cho, Yong Sun Cho, Soon Woo Hong, Hyung Jin Cho, Ki Yong Kim; J Korean Soc Fract 2000;13(1):81-86. Published online January 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.1.81

Abstract PDF: PURPOSE
To evaluate the results of open tibial fractures treated with unreamed AO intramedullary nail MATERIALS AND METHODS: Among the patiens of open tibial fractures who were treated with unreamed AO intramedullary nail from January 1993 to August 1998, the authors reviewed 34 patients whose follow-up was possible for more than one year. Fourteen patients were treated with AO external fixator after meticulous debridement, followed by unreamed AO intramedullary nailing, and the other 20 patients were treated with primary unreamed AO intramedullary nailing after debridement. The authors evaluated the results by the union time and the presence of complication.
RESULTS
The average union time was 26.3 weeks. There was no significant difference of union time and complications between the patients who were treated with AO exteranl fixator followed by unreamed AO intramedullary nailing and the patients who were treated primarily with debridement and unreamed AO intramedullary nailing. However there was high incidence(21%) of interlocking screw breakage.
CONCLUSION
With meticulous debridement and close observation of the wound, the open tibial fractures can be effectively treated with unreamed AO intramedullay nailing. Unreamed intramedullary nailing of open tibial fractures immediately after trauma can be recommended in selected cases.

Operative Treatment of Metacarpal Shaft Fracture: Bum Soo Kim, Sung Do Cho, Yong Sun Cho, Tae Woo Park, Hwa Chel Cheong, Soon Woo Hong, Soo Hyun Cho; J Korean Soc Fract 1999;12(3):720-726. Published online July 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.3.720

Abstract PDF

The goal of treatment of fractures of the metacarpals includes the restoration or preservation of hand function. To accomplish this goal, the physician must select a method that will offer the least soft tissue damage and accelerate the mobilization of the injured part as soon as the fracture stability permits. The majority of fractures of metacarpals can be effectively treated by nonoperative approach, but when several metacarpals are fractured, when there is open soft tissue trauma, and when there are displaced fractures that cannot be reduced or cannot maintain the reduction, internal fixation is indicated. The authors reviewed 117 cases of metacarpal shaft fractures on which the operative treatment was performed. Closed reduction and percutaneous Kirschner wire fixation were performed on the 62 cases, open reduction and Kirschner wire fixation were performed on the 12 cases, closed reduction and percutaneous screw fixation were performed on the 16 cases, and open reduction and plate and screw fixation were performed on the 27 cases. The patient was followed up for 36 months in average. The results were evaluated on the basis of total active motion of the fingers. The results were satisfactory in 92 percent of the cases in closed reduction and percutaneous Kirschner wire fixation cases, 75 percent in open reduction and Kirschner wire fixation cases, 85 percents in open reduction and plate and screw fixation cases, and all the cases of the patients in the closed reduction and percutaneous screw fixation cases. The closed reduction and percutaneous screw fixation provided relatively stable fixation and minimal soft tissue injury, so the injured hand could be mobilized soon after the operation, and consequentely the excellent outcome was accomplished. So the authors suggest that in selected cases, the closed reduction and percutaneous screw fixation can be used as one of the good treatment methods in the treatment of metacarpal fractures.

Result of Surgical Treatment of Calcaneal Fractures Using Extensile Lateral Approach: Sung Do Cho, Yong Sun Cho, Bum Soo Kim, Tae Woo Park, Gi Bong Kim, Key Yong Kim; J Korean Soc Fract 1999;12(2):320-327. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.320

Abstract PDF

Thirty-eight calcaneal fractures were treated with open reduction and internal fixation using extensile lateral approach from Jun. 1993 to Dec. 1996 and were followed more than a year. According to the Essex-Lopresti classification, there were 28 cases of joint depression type and 10 cases of tongue type. According to the Sanders classification, there were 20 cases of type II, 13 cases of type III and 5 cases of type IV. The purpose of this study is to analyze the results of surgical treatment of calcaneal fractures using extensile lateral approach and its complications. The results were as follows; 1. B.. ohler angle was improved from -2.4degrees to 20.5degrees and Gissane angle was improved from 114.5degrees to 120.4degreesafter the operation. The height of the calcaneus was improved from 75% to 95% and the width of the calcaneus was reduced from 119% to 106% of contralateral side. 2. yThe postoperative reduction status of the articular surface was analyzed by computed tomography(CT) in 18 patients and was found to be less than 2 mm of step-off in 10 cases, between 2 and 5 mm in 7 cases and more than 5 mm in 1 case. 3. Based on the assessment criteria of Salama et al., the functional results were excellent in 10 cases, good in 14 cases, fair in 10 cases, and poor in 4 cases. Unsatisfactory results were correlated with severity of articular comminution and failure to obtain accurate reduction of the articular surface. 4. Fourteen cases (36.8%), developed postoperative complications such as heel pain, causalgia and numbness, subtalar arthritis, marginal necrosis of wound, lateral subfibular impingement and heel bulging. In conclusion, Because of high incidence of postoperative complications, careful and meticulous exposure technique in doing extensile lateral approach are necessary for a satisfactory outcomes.

Isolated Fracture Dislocation of the Tarsal Navicular: Case report: Bum Soo Kim, Sung Do Cho, Yong Sun Cho, Tae Woo Park, Chang Sung So; J Korean Soc Fract 1997;10(4):925-928. Published online October 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.4.925

Abstract PDF

Isolated fracture dislocation of the tarsal navicular bone is a very rare injury. The mechanism of injury of this fracture dislocation is known as a horiBontal or axial load in plantar flexed foot. Anatomical reduction using closed or open methods is recommended for displaced navicular fractures to achieve a satisfactory result and early mobilization of the foot is required to get a good range of motion at the tarsal joint. Authors report one case of isolated fracture dislocation of the tarsal navicular which was treated with closed reduction and percutaneous K-wire fixation.
