Iatrogenic Subtrochanteric Fractures Related to the Surgical Error: Two Cases Report: Kook Jin Chung, June Young Jeon, Hyun Woo Na, Ji Hyo Hwang; J Korean Fract Soc 2015;28(4):250-255. Published online October 31, 2015; DOI: https://doi.org/10.12671/jkfs.2015.28.4.250

Iatrogenic fracture is not popular and might be recognized as a malpractice. Surgical error related to iatrogenic fracture which has occurred after an operation can be detected only by a surgeon. Stress riser fracture is another form of iatrogenic fracture also known as a Young's modulus fracture. As the majority of surgical related stress riser fractures can be preventive, the accurate prevalence is not known. The majority of fractures occurred in the weight bearing bones such as femur and tibia. The subtrochanter area is the most stress concentrated area in the human body, thus it is a common area for occurrence of stress riser iatrogenic fractures. We experienced 2 cases of stress riser iatrogenic fractures, which are related to technical errors, thus we report cases with literature review.

Results of Asian Type Gamma 3 Nail in Treatment of Trochanteric Fractures: Bing Zhe Huang, Yong Wook Park, Jin Su Park, Kyu Cheol Noh, Soung Yon Kim, Kook Jin Chung, Hong Kyun Kim, Hyong Nyun Kim, Yong Hyun Yoon, Ji Hyo Hwang; J Korean Fract Soc 2014;27(3):213-221. Published online July 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.3.213

Abstract PDF

PURPOSE
This study was conducted in order to demonstrate the radiologic and clinical results of using the Asian type gamma 3 nail in treatment of trochanteric fractures.
MATERIALS AND METHODS
Patients underwent operations with gamma 3 nails between August 2010 and August 2012. For the radiologic evaluation, we analyzed bone quality, fracture pattern, reduction quality, union period, and position of lag screw (tip-apex distance, Cleveland index). For the clinical evaluation, we analyzed mobility score of Palmer and Parker and Jensen's functional score.
RESULTS
The mean union was taken at 17.4 weeks (14-25 weeks). Two cases (4.3%) underwent reoperation due to cutting out of the hip screws. The clinical outcomes of Parker and Palmer's average mobility score changed from 7.3 to 5.8 (79%), Jensen's functional score was 1.3 to 1.8 (72%).
CONCLUSION
We achieved excellent clinical and radiological outcomes; therefore, Asian type gamma 3 nail is effective in treatment of trochanteric fractures of the femur in Korea.

Results of Tension Band Wiring and Additional Circumferential Wiring in Treatment of Comminuted Patella Fracture: Young Min Lee, Kook Jin Chung, Ji Hyo Hwang, Hong Kyun Kim, Yong Hyun Yoon; J Korean Fract Soc 2014;27(3):206-212. Published online July 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.3.206

Abstract PDF

PURPOSE
The purpose of this study is to evaluate the results of tension band wiring and additional circumferential wiring in treatment of comminuted patella fractures.
MATERIALS AND METHODS
A retrospective study of 67 patients with follow-up period longer than six months who underwent tension band wiring and additional circumferential wiring for comminuted patellar fracture from January 2004 to December 2012 was conducted. Analysis was based on radiological evaluation of bony union and articular surface displacement, and clinically by evaluating the postoperative function of the knee joint using the Levack scoring system.
RESULTS
Only one case out of 67 (1.5%) showed nonunion without metal breakage while good bone union was achieved in all other cases. Excluding the nonunion case, range of motion was 90 degrees minimum, 135 maximum, 129 on average. Average displacement was less than 2 mm, and 64 out of 67 cases showed satisfactory outcome with excellent functional score according to the Levack scoring system.
CONCLUSION
Tension band wiring and additional circumferential wiring technique for treatment of comminuted patella fractures can be considered as an effective treatment for achievement of good bone union and restoration of normal knee function.

Analysis of the Fixation Failure in Intertrochanteric Hip Fractures Treated with Hip Nailing: Jun Dong Chang, Tae Young Kim, Ji Hyo Hwang, Seul Ki Min, Je Hyun Yoo; J Korean Fract Soc 2012;25(3):169-176. Published online July 31, 2012; DOI: https://doi.org/10.12671/jkfs.2012.25.3.169

Abstract PDF

PURPOSE
To analyze the patterns of and risk factors for fixation failure after hip nailing in intertrochanteric (IT) hip fractures.
MATERIALS AND METHODS
Fourteen patients who sustained a fixation failure after hip nailing for IT hip fractures were enrolled in this study. The mean age at the index surgery was 74.5 years and the mean time to the fixation failure was 6.6 weeks. All of the serial radiographs up to the fixation failure and pre-operative 3-D computed tomography were analyzed.
RESULTS
According to AO classification, there were 7 stable fractures and 7 unstable ones. Of the total of 14 cases, 10 showed a comminution of the greater trochanter tip and incomplete anatomical reduction of the medial and anterior cortex at the fracture site. Of the 10 cases with appropriate position of the lag screw within the femoral head, 9 showed a high pertrochanteric fracture (HPF) pattern. The mechanism of the fixation failure was rotation of the femoral head in 7 of 9 cases with HPF and varus collapse of the proximal fragment in 4 of the other 5 cases.
CONCLUSION
The HPF pattern, the comminution of the greater trochanter tip, and incomplete reduction of the medial and anterior cortex may be additional risk factors of fixation failure after treating IT hip fractures with hip nailing in.

Operative Treatment of Bilateral Tibial Tuberosity Fractures in Adolescent: A Case Report: Hong Kyun Kim, Jung Han Yoo, Yong Wook Park, Jin Soo Park, Kyu Cheol Noh, Kook Jin Chung, Keun Jong Jang, Ji Hyo Hwang; J Korean Fract Soc 2010;23(3):317-320. Published online July 31, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.3.317

Abstract PDF: Bilateral avulsion fractures of the tibial tubercles are extremely rare. There is no case report about this in Korean literature. We present simultaneous bilateral tibial tuberosity fractures in 14-year-old adolescent male fell on the ground during running. These fractures were managed by open reduction and screw fixation. We gained complete union and removed metal after 6 months. Functional results were excellent 6 month after surgical treatment.

The Treatment of Femur Fractures in Neonates with a Pavlik Harness: Two Cases Report: Bon Seop Koo, Kyung Chul Kim, Ji Hyo Hwang; J Korean Soc Fract 2000;13(4):1033-1037. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.1033

Abstract PDF: Femur fractures during birth are very rare and the treatment of the fractures is variable. Pavlik harness is available in the treatment of the femur fractures in infants but any literature on the treatment of the birth fractures of femurs can not be found as far as we know. We experienced two cases of femur fractures in neonates treated with Pavlik harness and present them with a review of the literature.
