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.

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.

Treatment for the Supracondylar Fractures of the Distal Humerus with Cannulated Screw: Jin Soo Park, Young Khee Chung, Jung Han Yoo, Kyu Cheol Noh, Kook Jin Chung, Dong Nyoung Lee; J Korean Fract Soc 2007;20(1):58-63. Published online January 31, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.1.58

Abstract PDF: PURPOSE
To evaluate the results of the treatment of the supracondylar fractures of the humerus according to the fixation methods with cannulated screw.
MATERIALS AND METHODS
Eight patients, aged 49 to 82 years (average, 65 years), were reviewed after a mean follow-up of 16 months (range, 12~24 months). According to AO classification all fractures were classified as type A2 (simple transverse supracondylar fracture). All patients underwent closed reduction. Percutaneous fixation with cannulated screws was performed in 8 patients. Three of 8 patients had associated medical problems and one patient had distal radius fracture. The functional results were assessed by the Mayo Elbow Performance Score.
RESULTS
Mean operation time was 59 minutes (45~75) and all the patients with cannulated screw fixation had bony union and were able to early ROM exercise. Mean ranges of motion was 5~120 degrees with excellent functional results. Functional evaluation of elbow joint by Mayo method showed mean value of 88 (75~95).
CONCLUSION
The cannulated screw fixation of supracondylar fracture of humerus, especially in the elderly aged group with medical disease had excellent functional results (rigid fixation & early ROM exercise) due to shortening of surgery time and anesthesic time, combined with decreased technical difficulties of the surgical procedure

Two-part and Three-part Fractures of the Proximal Humerus Treated with the Polarus Interlocking Nail: A Comparison of Fracture Types: Kyu Cheol Noh, Yung Khee Chung, Kook Jin Chung, Sung Ku Hong; J Korean Fract Soc 2006;19(2):182-187. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.182

Abstract

PURPOSE
To evaluate the radiographic and clinical outcomes of patients with displaced proximal humerus fractures (two-part and three-part) treated with the Polarus interlocking nail, comparing their fractures types.
MATERIALS AND METHODS
There were 22 patients with displaced proximal humerus fractures. There were 10 surgical neck (SN) and 1 anatomical neck (AN) two-part fractures and 10 greater tuberosity/surgical neck (GT/SN) and 1 GT/AN three-part fractures. All patients were surgically treated solely with the Polarus interlocking nail using a closed technique. Functional assessment was obtained using the American Shoulder and Elbow Surgeons (ASES) score, which grade outcomes as excellent (>75), satisfactory (50~75), poor (<50) results. Radiographic outcome measurements included fracture alignment (neck-shaft angle), loosening of screw, fixation and hardware failure, and malunion and nonunion.
RESULTS
Overall, the average ASES score was 80.2 (range 46.0 to 98.0). There were 15/22 (68.2%) excellent, 6/22 (27.3%) satisfactory, and 1/22 (4.5%) poor results. All shoulders healed radiographically without evidence of avascular necrosis of the humeral head. When comparing patients with two-part fractures (n=11) with patients having three-part fractures (n=11), there were statistically significant differences with ASES outcome measures (p<0.05). But, there were no statistically significant differences in age-related analysis (p>0.05).
CONCLUSION
Both displaced two-part fractures and three-part GT/SN fractures can have above satisfactory functional and radiographic outcomes with the Polarus interlocking nail using a closed technique. Even though displaced three-part GT/SN fractures in elderly osteopenic patients (>60 years), we treated successfully with the Polarus interlocking nail.

Subtalar Distraction Arthrodesis for Calcaneal Malunion: Hyung Jin Chung, Jae Kwang Yum, Kook Jin Chung, Jae Min Jeon; J Korean Fract Soc 2006;19(1):34-40. Published online January 31, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.1.34

Abstract

PURPOSE
To evaluate the results and efficacy of the subtalar distraction arthrodesis on patients with complications due to malunion after intra-articular calcaneal fracture.
MATERIALS AND METHODS
From October 2001 to September 2004, we operated on 10 patients (14 cases). There were 9 male patients and one female; their mean age was 41 years old. Ten cases among them were operated initially. The mean period between initial injury and arthrodesis was 18 months. The mean follow up period was 16 months. During the operation, we used extensile lateral approach and arthrodesis was performed using tricortical bone block and cannulated screws. The ankle-hindfoot scale was used for clinical evaluation. In radiologic analysis, plain X-ray and CT of the both feet were examined for union and various parameters.
RESULTS
Thriteen cases achieved radiologic bone union. The mean ankle-hindfoot scale (maximum: 94 points) increased from 52.4 points preoperatively to points 77.2 at the final follow-up. The radiologic analysis of the pre and postoperative standing lateral radiograph showed mean increase of 6.9 mm in talo-calcaneal height, 5.2 degrees in talocalcaneal angle, 4.3 degrees in talar declination angle and average decrease of 4.5 degrees in talo-first metatarsal angle.
CONCLUSION
The short term result of the subtalar distraction arthrodesis using tricortical bone block was promising, but longer follow-up will be needed.

Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.1034

Abstract PDF: Fracture of the lateral condyle of humerus in children are common injury next to supracondylar fracture in children, account for 10 to 15% about the elbow and 18 to 20% about distal humerus fractures. This is the one fracture that can be overlooked clinically and that has a high potential for nonunion and cubitus valglls deformity. Sixty children treated by closed or open reduction with internal fixation on the lateral condyle fracture of humerus from January 1994 to August 1997, were reviewed. Almost fractures were treated within 12 hours after injury for the purpose of prevention of further displacement and occurrence of complication. According to Hardacre et als criteria, most patients showed excellent and good results. We report the result after surgical treatment on the laterdl condyle fracture of humerus in children.

Compartment Syndrome Complicating Avulsion Fractures of the Tibial Tubercle: Yerl Bo Sung, Jin Hyok Kim, Hyung Jin Chung, Dong Soo Kim, Byung Hyun Jung, Jong Guk Ahn, Chil Soo Kwon, Kook Jin Chung, Bong Gyun Kang; J Korean Soc Fract 1999;12(2):284-289. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.284

Abstract PDF: Avulsion of the tibial tubercle is an uncommon physeal injury. Complications from this fracture have rarely been reported and seldom affect the long-term outcome. Three adolescent boys who sustained avulsion fracture of the tibial tubercle, were complicated by compartment syndrome and treated at Inje University Sang-Gye Paik Hospital from September 1989 to February 1995. Injury to the soft tissue surrounding the tibial tubercle avulsion may be more extensive than is usually appreciated. The anatomy of the proximal tibia and the tibial tubercle with nearby branches of the anterior tibial recurrent artery suggest a predisposing factor for the development of compartment syndrome. So, compartment syndrome should be added to the list of possible complications of this type of fracture.
