Proximal Femoral Nail Antirotation versus Compression Hip Screw with Trochanter Stabilizing Plate for Unstable Intertrochanteric Hip Fractures: Jae Young Rho, Sang Bum Kim, Youn Moo Heo, Seong Jin Cho, Dong Sik Chae, Woo Suk Lee; J Korean Fract Soc 2010;23(2):161-166. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.161

PURPOSE
To analyze and compare the clinical and radiologic results of treatments in unstable intertrochanteric fractures of the femur with proximal femoral nail antirotation (PFNA) and compression hip screw with trochanter stabilizing plate (CHS with TSP).
MATERIALS AND METHODS
We retrospectively reviewed the results of 66 cases of unstable intertrochanteric fractures of the femur treated with PFNA (Group I) and CHS with TSP (Group II) which could be followed up for minimum a year. We evaluated several comparative factors such as operation time, blood loss, time to bone union, changes in neck-shaft angle, sliding of screw (or blade), complications, postoperative pain, social-function score of Jensen, and mobility score of Parker and Palmer.
RESULTS
Group I showed shorter operation time and less blood loss with significance than group II (p<0.05), but there were no differences between the groups in the mean time to bone union, changes in neck-shaft angle, sliding of screw (or blade), complications, postoperative pain, and social-function score of Jensen (p>0.05). Two cases of cutting out of the blade through the femoral head were found in group I. One case of cutting out of the screw, one case of the breakage of the plate, and loosening of the plate were found in group II as complications.
CONCLUSION
We think that there were no significant differences between PFNA and CHS with TSP in view point of radiologic and clinical outcomes in unstable intertrochanteric fractures of the femur, but PFNA is less invasive device than CHS with TSP, therefore it may be useful device in elderly patients.

The Comparison of Minimally Invasive Plate Osteosynthesis and Intramedullary Nailing in the Treatment of the Proximal and Distal Tibia Fracture: Joon Soon Kang, Seung Rim Park, Sang Rim Kim, Yong Geun Park, Jae Ho Jung, Sung Wook Choi; J Korean Fract Soc 2010;23(2):172-179. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.172

Abstract PDF

PURPOSE
To compare the efficacy of the surgical treatment through the comparison of Minimally Invasive Plate Osteosynthesis (MIPO) and Intramedullary (IM) nailing in the treatment of the tibial shaft fractures expended to metaphysis retrospectively.
MATERIALS AND METHODS
Patients with proximal or distal third fracture of tibial shaft from May 2003 to Aug. 2006 were divided into two groups depending on the surgical method. Group A consisted of 30 patients treated with IM nailing, Group B was 29 patients treated with MIPO. The clinical outcomes were evaluated retrospectively from the time for bone union and callus formation confirmed by X-ray, functional score of knee or ankle joint, and complications including nonunion, malalignment and infection.
RESULTS
Bone union was seen radiologically at a mean of 17.4 weeks in group A, and 17.0 weeks in group B. In postoperative complications, group A showed two nonunion, two delayed-union, six malalignment, and two wound infection while group B showed only one delayed-union and one wound infection.
CONCLUSION
There were no significant differences in the time for bony union and functional score between IM nailing and MIPO. Conventional IM nailing with only interlocking technique showed higher incidence of malalignment and deformity than MIPO for the treatment of the proximal or distal third fracture of the tibial shaft.

Intra-articular Calcaneal Fractures Treated with Open Reduction and Internal Fixation: A Comparative Study between Groups with and without Bone Graft: Hong Moon Sohn, Sang Ho Ha, Jun Young Lee, Sung Hwan Jo, Hoon Yang; J Korean Fract Soc 2010;23(2):180-186. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.180

Abstract PDF

PURPOSE
This study compares the clinical results of open reduction and internal fixation with and without bone graft for the treatment of intra-articular calcaneal fractures.
MATERIALS AND METHODS
Twenty-five patients who had open reduction and internal fixation for intra-articular calcaneal fractures and available for at least 1 year of follow-up were included in this study. Fifteen cases were operated with bone graft. Period to bone union and functional evaluation score were compared between both groups with analysis of complications.
RESULTS
Bone union was achieved in all cases with average bone union time of 11.6 weeks and 12.8 weeks in group with and without bone graft respectively. Creighton-Nebraska Health Foundation (CNHF) functional score was 86.5 points and 80.3 points respectively. The period to bone union and the CNHF score in the comparison of two groups were statistically insignificant. Complications were observed in four cases of group without bone graft and 5 cases of group with bone graft.
CONCLUSION
This study indicates that bone graft does not play a significant role in bone union and functional outcome when intra-articular calcaneal fractures are treated with open reduction and internal fixation.

Surgical Treatment of Pathologic Humeral Fracture: Ho Jung Kang, Byoung Yoon Hwang, Jae Jeong Lee, Kyu Ho Shin, Soo Bong Hahn, Sung Jae Kim; J Korean Fract Soc 2010;23(2):187-193. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.187

Abstract PDF

PURPOSE
To evaluate and analyze the radiographic and clinical outcomes after the surgical treatments of pathologic humeral fractures.
MATERIALS AND METHODS
From October 1993 to September 2007, a retrospective investigation was conducted with a total of 13 patients who underwent operations for pathologic humeral fractures. The methods of surgical treatment were as follows-four cases of open reduction and internal fixation; eight cases of closed reduction and internal fixation with intramedullary nailing; and one of radical excision and hemiarthroplasty.
RESULTS
Of nine patients with metastatic bone lesions, three were diagnosed with primary cancer after the incidence of pathologic humeral fracture. The mean period between the diagnosis of primary cancer and pathologic fracture in the latter six cases was 36.7 (2~144) months and the mean survival period after the surgical treatments was 22.8 (12~35) weeks in all patients with bone metastasis. Fracture unions were noted in all four cases of primary humeral bone lesion but none in metastatic cases. Pain relief and functional recovery were noted in eleven patients of this study.
CONCLUSION
Satisfactory clinical outcomes with sustained pain relief and functional recovery were observed after the surgical treatments of pathologic humeral fracture. Benign bone lesions require more active and early treatments in order to facilitate the functional recovery of upper extremities and fracture union. With pathologic humeral fractures originated from metastasis, palliative treatments were preferred to fracture union method for planning long-term pain relief and functional recovery.

Double Parallel Plates Fixation for Distal Humerus Fractures: Young Hak Roh, Moon Sang Chung, Goo Hyun Baek, Young Ho Lee, Hyuk Jin Lee, Joon Oh Lee, Kyu Won Oh, Hyun Sik Gong; J Korean Fract Soc 2010;23(2):194-200. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.194

Abstract PDF: PURPOSE
The purpose of this study was to review the outcome of fixation of distal humerus fractures using recently-introduced double parallel plate system in sagittal plane.
MATERIALS AND METHODS
From May 2004 to June 2008, seventeen patients with distal humerus fractures underwent primary open reduction and internal fixation with double parallel plates. According to the AO classification, there were 2 A3, 2 C1, 7 C2, and 6 C3 type fractures. Outcome assessment was performed by using the Mayo Elbow Performance index (MEPI).
RESULTS
At a mean follow up of 18 (range, 12 to 32) months, 4 patients were rated as excellent, 8 as good, and 5 as fair in terms of MEPI. The average arc of elbow flexion after primary operation was 116 (range, 90~140) degrees with a mean flexion contracture of 13 (range, 0 to 30) degrees. One patient required reoperation due to fixation failure and six patients underwent capsulolysis and three patients underwent ulnar nerve neurolysis. The time to begin elbow motion exercise had negative correlation with total elbow range of motion and multiple trauma patients had significantly lower MEPI functional score compared to those without combined injury.
CONCLUSION
Double parallel plating allowed adequate fixation for distal humerus fractures regardless of patient age and fracture pattern. Partial ankylosis and unlar nerve compression symptoms were the main causes of reoperation.

Clinical Outcome of Surgical Treatment for Intra-articular Distal Humerus Fracture: Myung Jin Lee, Hyeon Jun Kim, Sung Keun Sohn, Kyu Yeol Lee, Sung Soo Kim, Chul Hong Kim, Lib Wang, Hyun Woo Sung; J Korean Fract Soc 2010;23(2):201-205. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.201

Abstract PDF

PURPOSE
To evaluate functions of the elbow joint according to surgical approach, time to exercise, and type of fracture after surgical treatment for the intra-articular comminuted fracture of the distal humerus.
MATERIALS AND METHODS
27 patients with the intra-articular comminuted fractures of the distal humerus underwent surgery from March, 2000 to January, 2007. We investigated the surgical approach, time for union, time to exercise and age. We also evaluated postoperative functions of the elbow joint according to the flexion contracture, the range of motion and the Mayo elbow performance score.
RESULTS
The average follow-up period was 37 months and the average time for union was 14 weeks. The average range of flexion was 115 degrees, the average flexion contracture was 10 degrees, and the Mayo elbow performance score with average value of 85 point showed good clinical results. There were no statistically significant differences in functions of the elbow joint according to the operative method and age. However, patients with early postoperative exercise within 6 days showed statistically better outcomes than patients with postoperative exercise after 7 days. Type C1, 2 fractures showed statistically better results than the type C3 fracture.
CONCLUSION
Stable fixation and early exercise are required to prevent postoperative complications and restore functions of the elbow joint with an intra-articular comminuted fracture of the distal humerus.

Treatment of Femoral Shaft Fracture with Interlocking Humeral Nail in Older Children and Adolescent: Kun Bo Park, Hoon Park, Hyun Woo Kim, Hui Wan Park, Jae Young Roh; J Korean Fract Soc 2010;23(2):206-212. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.206

Abstract PDF: PURPOSE
To evaluate the results of interlocking humeral nail for femur shaft fractures through the greater trochanter in older children and adolescent.
MATERIALS AND METHODS
Eleven femoral shaft fractures in ten patients were selected. They were consisted of 9 boys and 1 girl. Two patients had osteogenesis imperfecta and one patient had a simple bone cyst as an underlying disease. 7 cases were right side and 4 cases were left side. The mean age at the time of operation was 12 years and 7 months (8 years 11 months~15 years 7 months). The mean follow-up period was 21 months and interlocking humeral nail was inserted at the greater trochanter in all patients.
RESULTS
All patients had a complete bony union without any complication such as infection, nonunion, leg length discrepancy and metal failure. Avascular necrosis of femoral head and coxa valga were not developed in all patients.
CONCLUSION
Intramedullary nailing through the greater trochanter using interlocking humeral nail is effective and safe treatment for the femoral shaft fracture in older children and adolescents.

Related Factors of Ligamentotaxis with Posterior Instrumentation for the Surgical Treatment of Thoracolumbar Bursting Fracture: Sang Bum Kim, Taek Soo Jeon, Seung Hwan Kim, Han Chang, Cheol Mog Hwang; J Korean Fract Soc 2010;23(2):213-219. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.213

Abstract PDF: PURPOSE
To investigate factors influencing the amount of indirect reduction by ligamentotaxis according to timing of surgery, extent of surgery, and characteristics of fractures.
MATERIALS AND METHODS
We reviewed 22 cases of thoracolumbar fracture which had been performed posterior instrumentation and fusion using pedicle screw system. We divided patients into each group according to timing of surgery, number of fusion segment, insertion of screw on fractured vertebra, and rupture of posterior ligament complex, and Denis type. We measured changes of kyphotic angle, anterior vertebral height and wedge angle on plain radiographs, and we compared spinal canal area before and after operation using computed tomographic scans.
RESULTS
Kyphotic angle, anterior vertebral height, wedge angle, and area of spinal canal showed significant improvement postoperatively. The wedge angle improved significantly operated within 3 days after injury, however, kyphotic angle and anterior vertebral height had no correlation with variable factors except the rupture of posterior ligament complex. The amount of restoration of spinal canal also affected only by rupture of posterior ligament complex.
CONCLUSION
There is little relationship between timing of surgery and canal restoration, so we cannot conclude that prompt operation helps reduction of narrowed spinal canal. Otherwise narrowed spinal canal had much less restored by ligamentotaxis when there were rupture of posterior ligament complexes.

Effect of Fracture Gap on Biomechanical Stability of Compression Bone-Plate Fixation System after Bone Fracture Augmentation: Duk Young Jung, Sung Jae Lee, Seon Chil Kim, Jong Keon Oh; J Korean Fract Soc 2010;23(2):220-226. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.220

Abstract PDF: PURPOSE
The goal of this study using the biomechanical test was to evaluate the mechanical stability of the bone-plate fixation system according to changes of the fracture gap sizes and widths.
MATERIALS AND METHODS
For mechanical test, four types with different fracture models simulating the clinical situations were constructed depending on the gap size (FGS, mm) and the gap width (FGW, %) at the fracture site: 0 mm/0%, 1 mm/100%, 4 mm/100%, 4 mm/50%. For analyzing the effects of fracture gap on the biomechanical stability of the bone-plate fixation system, 4-point bending test was performed under all same conditions.
RESULTS
It was found that the fracture gap sizes of 1 and 4 mm decreased mechanical stiffness by about 50~60% or more. Furthermore, even without fracture gap size, 50% or more fracture gap width considerably decreased mechanical stiffness and suggested the possibility of plate damage through strain results.
CONCLUSION
Our findings suggested that at least 50% contact of the fracture faces in a fracture surgery would be maintained to increase the mechanical stability of the bone-plate fixation system.

Bursting Fracture of the Proximal Femur during Insertion of Unreamed Femoral Nail for Femur Shaft Fracture: A Case Report: Ji Wan Kim, Seong Eun Byun, Won Hyuk Oh, Jung Jae Kim; J Korean Fract Soc 2010;23(2):227-231. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.227

Abstract PDF

When treating femur shaft fracture in adults, undreamed nail can be an option in order to avoid systemic complications. To appropriately insert unreamed intramedullary nail, an accurate entry point and sufficient reaming of the entry portal is essential. The intramedullary canal of the proximal femur must be reamed over than the diameter of the proximal end of the nail. If the proximal reaming is not sufficient, complications such as bursting fracture of proximal femur can occur. We present two cases of bursting fracture of proximal femur following insertion of undreamed intramedullary nail as well as a literature review.

Fracture-Dislocation of S1 in 3-Year-Old Boy: A Case Report: Sang Bong Ko, Sang Wook Lee; J Korean Fract Soc 2010;23(2):232-235. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.232

Abstract PDF: Fracture-dislocation of the sacrum that has not yet fully developed is common in the distal sacrococcygeal joint of children, but this injury is rarely seen in 1st Sacrum. Most of these patients have a severe neurological deficit, so this injury generally requires surgical decompression. We managed a three year old patient who had a S1 fracture-dislocation without a neurological deficit, and the patient was treated with simple skin traction and bed rest without surgery. The child had a satisfactory result, so we report on this case with reviewing the relevant literatures.
