The Clinical Results of Opening Wedge Osteotomy in the Volarly Malunited Distal Radius: Seoung Joon Lee, Jin Ho Choi; J Korean Fract Soc 2014;27(1):29-35. Published online January 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.1.29

Abstract PDF: PURPOSE
To report the clinical results of opening wedge osteotomy graft in the volarly malunited distal radius.
MATERIALS AND METHODS
Ten patients with volarly malunited distal radius fractures treated by opening wedge osteotomy were included in this study. Grip power, range of motion of the wrist, radiographic parameter and Mayo wrist scores were retrospectively evaluated.
RESULTS
At the final follow-up, the rotation of the forearm, the range of motion of wrist, and the grip power were improved. The average radial inclination improved to 22.2degrees, the average volar tilting improved to 5.6degrees, and the average ulnar variance improved to 0.8 mm. The average Mayo wrist score was improved to 85.6.
CONCLUSION
Opening wedge osteotomy for volarly malunited distal radius was considered as one of the good treatments to restore anatomy of the distal radius and distal radioulnar joint and also to improve the function of the wrist joint.

Intrapelvic Anterior Plate Fixation for Crescent Fracture-Dislocation of Sacroiliac Joint: Kwang Jun Oh, Jin Ho Choi; J Korean Fract Soc 2013;26(3):184-190. Published online July 31, 2013; DOI: https://doi.org/10.12671/jkfs.2013.26.3.184

Abstract PDF: PURPOSE
To evaluate the radiological and clinical outcomes of intrapelvic anterior plate fixations for Day Classification Type II crescent fracture-dislocations of sacroiliac joints.
MATERIALS AND METHODS
Ten patients who had undertaken the surgical treatment for the sacroiliac joint from 2006 to 2012 were enrolled in this study. All cases fell into Type II by Day Classification for sacroiliac joint injuries. For surgical treatments, the plate fixation through the intra-pelvic anterior approach was first performed for all cases and anterior ring fixation was performed in 4 cases with more severely displaced anterior pelvic ring injuries. Then, radiological and clinical evaluation was implemented.
RESULTS
The bone union was observed from all patients whom performed the surgical fixation. In the radiological results, 9 cases with the anatomic and nearly-anatomic reductions were observed. Out of the 10 cases which performed the rotational displacement analysis, there were 3 excellent cases, 6 good cases and 1 fair case. The 10 cases that performed the deformity index and vertical displacement analysis, less variations were observed in the anterior ring fixations after intra-pelvic anterior plate fixation group. According to the clinical results, 4 excellent cases, 3 good cases, and 3 moderate cases were observed.
CONCLUSION
In the Type II crescent fracture-dislocation of sacroiliac joint, the intrapelvic anterior plate fixation achieved satisfactory anatomical reductions, radiological stabilities and clinical results.

Comparison of Surgical Outcomes in Thoracolumbar Fractures Having 6 or Less Scored by Load-Sharing Classification Based on Posterior Fusion Level: Jung Hoon Kim, Sung Soo Kim, Jin Ho Cho, Bo Hoon Jang, Jin Hwan Kim; J Korean Fract Soc 2013;26(1):21-26. Published online January 31, 2013; DOI: https://doi.org/10.12671/jkfs.2013.26.1.21

Abstract PDF: PURPOSE
The aim of this study is to decide the optimal level of fusion with comparing the results between the short segment fusion and long segment fusion treated with pedicle screw instrumentation, including fractured vertebra in thoracolumbar junctional fractures.
MATERIALS AND METHODS
From February 2000 to November 2009, fifty three patients with junctional fracture of thoracolumbar spine were treated with pedicle screws and posterior fusion at our hospital. They were divided into two groups, the short segment group and long segment group. Preoperatively, immediate postoperative and last follow-up lateral radiological evaluation was done by measuring the correction and loss of segmental kyphosis, wedge angle, body compression rate and instrumented vertebra angle. In addition, operation time and amount of intraoperative bleeding were measured.
RESULTS
There were no significant differences of statistical analysis regarding the radiological variables between the two groups, especially the loss of corrected segmental kyphosis, wedge angle, body compression rate and instrumented vertebra angle (p>0.05). However, operative time in the short segment group (234 minutes) was shorter than the long segment group (284 minutes), and there was statistical significance (p=0.002).
CONCLUSION
We recommend the short segment transpediculr instrumentation one level above and one level below, including the fractured vertebra for thoracolumbar junctional fracture with 6 points or less of the load-sharing score.

Attritional Flexor Tendon Ruptures after Malunited Distal Radial Fracture: A Case Report: Jin Ho Cho, Hyoung Keun Oh; J Korean Fract Soc 2006;19(1):93-95. Published online January 31, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.1.93

Abstract: Ruptures of extensor pollicis longus tendon after distal radial fractures are well-known. However, delayed flexor tendon rupture of finger as a complication of the fracture are less common. We report the case of delayed rupture of flexor digitorum profundus tendon to middle and ring fingers and flexor digitorum superficialis to ring finger in 72 year old female patient. She was treated by free tendon graft with palmaris longus tendon. After 1 year follow-up, range of motion and flexion power were recovered to nearly normal.

The Compression Hip Screw with Trochanter Stabilizing Plate for Internal Fixation of Unstable Intertrochanteric Fractures: Jin Ho Cho; J Korean Fract Soc 2005;18(3):221-226. Published online July 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.3.221

Abstract PDF: PURPOSE
To evaluate trochanter stabilizing plate and compression hip screw can prevent excessive impaction and cutting-out in unstable intertrochanteric fractures.
MATERIALS AND METHODS
One hundred twenty-one patients with intertrochanteric fractures were treated between December 1999 and March 2002. Of the patients, twenty-four patients were treated with an additional TSP on the CHS. Nineteen patients were followed for more than six months. The fractures were classified according to the AO classification. Impactions of compression lag screw were measured immediate postoperatively and postoperatively three months later on simple radiographs. Functional results were followed Salvati-Wilson assessment score at postoperative six months later.
RESULTS
The group consisted of seven men and twelve women, and the mean age was 73 years. Two were classified as A2.2, six A2.3, one A3.2, and ten A3.3 fractures. Mean impaction was 5.4 mm (range 1.8 to 11.4 mm). Functional results were excellent in 32% and good in 53%. Eighteen patients had healed after operation. One complication required a bipolar hemiarthroplasty due to cutting-out of lag screw.
CONCLUSION
In three-part and four-part intertrochanteric fractures with lateral cortex breakage or vertical fracture in greater trochanter, the addition of TSP to CHS can prevent abductor muscle weakness due to fracture impaction, limb shortening and additional lateral cortical fracture. It also helps early weight bearing and bone healing.

Fracture of the Distal Radius with Ulnar Nerve Palsy: Chil Soo Kwon, Jong Kuk Ahn, Jin Hyok Kim, Yerl Bo Sung, Jin Ho Cho; J Korean Soc Fract 1997;10(1):171-174. Published online January 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.1.171

Abstract PDF

There are several complications of distal radiug fracture such as median nerve injury, malunion nonunion, rupture of EPL, and ischemic contracture. Lesion of ulnar nerve as a complication of fracture of the distal radius are very rare. The authors report 1 case of the distal radius fracture with ulnar nerve palsy. The electromyography & nerve-conduction studies showed incomplete axonotmesis of ulnar nerve on 1 month following injury. A second electromyography & nerve-conduction study two months after injury showed complete recovery of nerve function.
