Reconstruction of Medial Collateral Ligament in Old Posterior Dislocation of the Elbow: Sang Soo Lee, Ho Yeun Hwang, Dong Hee Lee, Il Hyun Nam, Sang Un Lee; J Korean Soc Fract 2000;13(3):576-583. Published online July 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.3.576

Abstract PDF: PURPOSE
To evaluate and analyse the operative results of reconstruction of medial collateral ligament(MCL) in old posterior dislocation of the elbow.
MATERIALS AND METHODS
Nine patients (from 1989 to 1999) with old posterior dislocation of the elbow treated by operation were reviewed. We analysed the pattern of dislocation, associated injury, method of operation, complication and functional results. All patients were treated with open reduction. Reconstruction of MCL was undertaken in three patients of nine.
RESULTS
All nine patients who had underwent open reduction were improved in the flexion-extension motion of elbow. Three patients of nine underwent reconstructive surgery of MCL were much improved in the flexion-extension motion. But there is no differences in improving the pronation-supination motion between of them(P>0.05, ttest).
CONCLUSION
Precise understanding of MCL anatomy and appropriate intraoperative technique are mandatory. We achieved much more range of motion in the cases of reconstruction and early motion rather than those of immobilization for 3 weeks with K-wire. We believe reconstruction of MCL is a useful addition to treatment options for old elbow dislocation of elbow.

Posterior Short Segment Instreumntation and Fusion for the Unstable Thoracolumbar Spine Fracture: A Comparative Study: Ki Tack Kim, Gyu Pyo Hong, Dae Woo Hwang, Sang Un Lee, Sang Wook Bae; J Korean Soc Fract 2000;13(2):352-360. Published online April 30, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.2.352

Abstract PDF: INTRODUCTION : In treating of acute unstable thoracolumbar spine fractures, current trend is a toward short segment instrumentation to spare the motion segments. Many authors reported the result of short instrumentation and fusion, but there have been few reports about the effect of additional screw fixation at fractured vertebra in posterior short segment instrumentation and fusion. Therefore, the objective of this study is to compare the results of treatment between with/without screw fixation at the fractured vertebra in posterior short segment pedicle screw fixation. MATERIAL AND METHODS : Twenty-three patients with unstable thoracolumbar spine fractures were treated with posterior short segment instrumentation and fusion. Eleven cases classified into group A were not fixed at the fractured vertebre. They were followed up to average 45 months(24-79). Twelve cases classified into group B were treated with screw fixation at the injured vertebra and followed up to average 38 months(14-78). Authors evaluated the radiologic assessment, such as wedge angle of fractured body, local kyphotic angle and wedge index(the ratio of anterior body height to posterior body height), the neurologic assessment by Frankel grade system and functional assessment by Denis system.
RESULTS
: There was no complication resulted from additional pedicle screw fixation at fractured level. In rediologic assessment, wedge angle were measured at preoperative, postoperative and last follow-up time as follows; in group A, 22.2degrees -11.3degrees -14.1degrees and in group B, 19.5degrees -8.8degrees -9.8degrees . The local kyphotic angle measured were 17.9degrees -7.0degrees -14degrees in group A and 17.1degrees -6.3degrees -7.9degrees in group B. The wedge index were 42.9%-22.6%-28.5% in group A and 40%-19.5%-22.4% in group B. At last follow-up time, eight eases showed Frankel grade E and three cases showed grade D in group A, and all cases of group B were Frankel E. Denis pain score were satisfctory in all of both group and Denis work score were also satisfactory in two group except one case of group A.
CONCLUSIONS
: Additional screw fixation at fractured verteba did not cause any complication. There was no significant difference in reduction rate between two groups(P>0.05), but group B showed better maintenance of correction of kyphotic deformity than that of group A(P<0.05). In conclusion, it seems that additional screw fixation at fractured level may be better method in maintaining asgittal alignment and decreasing the risk collapsing of body.

Treatment of the Acromion Fracture: Sang Soo Lee, Bo Gun Seo, Dong Hee Lee, Il Hyun Nam, Sang Un Lee; J Korean Soc Fract 1998;11(4):941-946. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.941

Abstract PDF: Fractures of the acromion process are relatively rare, then no accepted treatment method has been established. The puroose of this study was to review of the acromion fracture in our cases, to determine trends in the mechanism of injury, the fracture pattern, and treatment method, and to evaluate the clinical results. 1. The types of fracture were type I-A in 4 cases, type I-B in 6 cases, type II in 6 cases, type III in 3 cases. 2. Clinical results were excellent in 9 cases(52.9%), good in 6 cases(29.4%), fair in 3 cases, poor in 1 case. 3. Type III fractures suggesting that early surgical intervention may be indicated.
