Result of Surgical Treatment for the Femoral Head Fracture: Joon Soon Kang, Kyoung Ho Moon, Tong Joo Lee, Jong Hyuck Yang; J Korean Fract Soc 2014;27(3):198-205. Published online July 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.3.198

Abstract PDF: PURPOSE
This study analyzed the clinical and radiological long-term follow-up results of patients with femoral head fracture who received surgical treatments.
MATERIALS AND METHODS
Retrospective evaluation was performed for 20 patients with femoral head fracture who received surgical treatments between December 1997 and May 2010. According to Pipkin's classification, there were five type I, six type II, one type III, and eight type IV fractures.
RESULTS
The average Merle d'Aubigne'-Postel score was 12.8 (12.80+/-3.53). According to surgical method, the score for the bony fragment excision group was 9.8 (9.83+/-2.79), and that for the open reduction and internal fixation group was 13.9 (13.92+/-3.07). Depending on Thompson-Epstein criteria, two patients were good, two were fair, and two were poor in the bony fragment excision group. Four patients were excellent, six were good, and three were poor in the open reduction and internal fixation group.
CONCLUSION
Bony fragment excision should be performed with caution in patients with femoral head fracture. Considering fragment size, location, and presence of acetabular fracture, better outcome can be expected using the open reduction and internal fixation method in comparison with excision.

Combined Anterolateral and Lateral Approaches in Treatment of Extra-articular Fracture of the Distal Humerus: Dae Gyu Kwon, Kyoung Ho Moon, Suk In Na, Byung Ki Shin, Tong Joo Lee; J Korean Fract Soc 2012;25(3):185-190. Published online July 31, 2012; DOI: https://doi.org/10.12671/jkfs.2012.25.3.185

PURPOSE
The purpose of this study was to analyze the clinical effectiveness of open reduction in the treatment of distal humeral fracture using a newly designed combined approach of anterolateral and lateral approaches to protect the radial nerve.
MATERIALS AND METHODS
We investigated 24 consecutive cases of distal humeral fracture who received open reduction and internal fixation with a plate and screws with a minimum follow-up period of 1 year. We analyzed the patients' age, sex, fracture pattern, timing of the union, range of motion of the elbow joint, and complications. The Mayo elbow performance index (MEPI) was employed for the assessment of elbow joint function.
RESULTS
Clinical union was observed at 10.8 weeks (6~20 weeks) on average. Pre-operatively, there were 3 cases of incomplete radial nerve palsy. All of the cases recovered, and there was no additional radial nerve palsy due to surgery. According to the MEPI, 13 cases were "excellent" and 10 cases were "good" or better, comprising 95.83% of the cases. The range of motion at the elbow was 5.5 degrees (0~15 degrees) of extension, and 131.5 degrees (120~145 degrees) of flexion, suggesting no functional disability. The duration of return to work was 11.2 weeks (5~32 weeks) on average. There were no nonunion, malunion, or infection complications.
CONCLUSION
The combined anterolateral and lateral approach we designed is a clinically effective approach due to facilitation of protection of the radial nerve and attainment of adequate fixation space.

Usefulness of the Cementless Stem for the Treatment of Hip Fracture in Elderly Patients with Osteoporosis: Comparative Analysis between Cementless Stem and Cemented Stem: Joon Soon Kang, Kyoung Ho Moon, Rhu Seop Kim, Sang Ho Lee, Jong Min Choi; J Korean Fract Soc 2011;24(1):16-22. Published online January 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.1.16

Abstract PDF: PURPOSE
We evaluated the usefulness of the cementless stem in treating hip fracture patients older than 70.
MATERIALS AND METHODS
We studied elderly osteoporotic hip fractures in the neck and intertrochanter area who had received hip arthroplasty with over 2 years of follow up period. Among those, we analyzed the clinical and radiological results of hip arthroplasty with cemented stem (group 1) and hip arthroplasty with cementless stem (group 2). Each group was consists of fifty hips.
RESULTS
The mean age at surgery was 75 years and mean follow-up period was 40 months (minimum 24 months). The admission period was 28.68+/-8.8 days for group 1 and 28.05+/-8.7 days for group 2 (p>0.05) and the average operation time was 87+/-21.2 minutes, and 80+/-17 minutes (p>0.05) and the total blood loss was 611+/-141.3 cc and 557+/-120.5 cc (p>0.05) respectively. There was no statistically significant difference in all aspects. One case of pulmonary embolism occurred in group 1. Stem loosening was not observed in both groups at the last follow-up radiologic study.
CONCLUSION
The hip arthroplasty with cementless stem for the osteoporotic hip fractures showed a competent results clinically and radiologically in short term follow up as compared with the cemented stem.

Operative Treatment of Displaced Intercondylar Fracture of the Distal Humerus with Reconstruction Plate: Ryuh Sup Kim, Tong Joo Lee, Kyoung Ho Moon, Seung Rim Park, Moon Lee; J Korean Fract Soc 2007;20(2):172-177. Published online April 30, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.2.172

Abstract PDF: PURPOSE
To evaluate the therapeutic effects of chevron olecranon osteotomy and bilateral reconstruction plate as operative treatment for distal humerus intercondylar fracture.
MATERIALS AND METHODS
Among patients operated for distal humerus intercondylar fracture in our hospital from June, 1997 to October, 2005, 26 patients were selected who could be followed-up for more than one year. The average follow-up period was 15 months. All olecranon osteotomies were chevron osteotomy and all fractures were treated with internal fixation using bilateral reconstruction plate. The ulnar nerve was checked in all cases. Three patients in which case the plate might irritate the ulnar nerve, received with ulnar nerve anterior transposition. Cassebaum's classification and Mayo elbow performance score were used to evaluate at three, six and twelve months.
RESULTS
Mean bone union period was 11.7 weeks. There were 9 excellent cases, 11 good cases, 4 fair cases and 2 poor cases. Mean flexion contracture was 11Â° and further flexion was 126Â° at last follow-up.
CONCLUSION
Bilateral reconstruction plate internal fixation using chevron olecranon osteotomy showed strong fixation and good clinical results and it is possible for early rehabilitation treatment.

Result of Interlocking Intramedullary Nailing for Humeral Shaft Fracture Evaluation of Post-operative Shoulder Function: Seung Rim Park, Tong Joo Lee, Ryuh Sub Kim, Kyoung Ho Moon, Dong Seok You; J Korean Fract Soc 2007;20(2):166-171. Published online April 30, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.2.166

Abstract PDF

PURPOSE
To evaluate the post-operative functional reduction of the shoulder joint and the impacting factors to post-operative shoulder joint function in interlocking IM nailing treatment of humeral shaft fracture.
MATERIALS AND METHODS
From April 1999 to August 2004, 35 patients (35 cases) whom admitted to hospital for humeral shaft fracture and treated using interlocking intramedullary nail were followed up for more than 1 year. 1 year post-operative shoulder joint function were evaluated using American Shoulder Elbow Surgery Scale (ASES). Pre-operative shoulder joint pain, radiologically degenerative change and extent of nail protrusion were evaluated, and each factor was correlated with function of the shoulder joint.
RESULTS
33 cases out of 35 cases showed union and average union period was 12 weeks. Complications consisted of 2 cases of nonunion, 1 case of infection, 1 case of loosening of distal fixing screw, 1 case of radial nerve palsy and 1 case of axillary nerve palsy. Shoulder joint function 3 months after operation : mean ASES score 78.2, 12 months after operation : mean ASES score 89.6. Pre-operative shoulder joint pain and nail protrusion showed to be statistically related to shoulder joint function.
CONCLUSION
If the operation leaves no protrusion of intramedullary nail, it can be concluded to be relatively safe and effective.

Management of Displaced-Extension Type Supracondylar Fractures of Humerus in Children: Suk Myun Ko, Myung Ku Kim, Kyoung Ho Moon, Ryuh Sup Kim, Kyu Jung Cho, Dong Hun Choi; J Korean Soc Fract 1999;12(2):351-360. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.351

Abstract PDF: From June 1996 to February 1998, we reviewed the cases of 27 patients who had a displaced - extension type supracondylar fracture of the humerus retrospectively. The mean length of follow-up was 1.3 years. According to Gartland classification, type II was 7 cases (26%), type III-A was 11 cases (41%), type III-B was 9 cases (33%). We treated with three different methods, including closed reduction and percutaneous Kirschner-wire fixation, skeletal traction, and cast application after closed reduction. In type II fractures, we used two parallel lateral pins. In type III fractures, we used 2 lateral parallel pins followed by 1 medial crossed pin predominantly. The results of treatment were assessed using the criteria of Flynn et al. We graded cosmetic and functional factors separately. Satisfactory results were achieved by percutaneous K-wire fixation(96%). There were seven neural lesions. These were the result of injury and not of the treatment, with exception of one case. Neural injuries spontaneously resolved at a mean of 2.5 months(range 1.5 to 5 months) after injury. Varus deformity was present in one patient. There was no Volkman's ischemic contracture. Percutaneous Kirschnerwire fixation is advocated as the method of choice for the majority of displaced-extension type supracondylar humerus fractures in children.
