Clinical and Radiological Analysis of Angular Deformity of Lower Extremities: Changhoon Jeong, Jong Ho Noh; J Korean Fract Soc 2017;30(3):156-166. Published online July 31, 2017; DOI: https://doi.org/10.12671/jkfs.2017.30.3.156

The alignment of lower extremities is an important consideration in many clinical situations, including fracture reduction, high tibia osteotomy, total knee arthroplasty, and deformity correction. Mal-alignment of lower extremities is not only a simple cosmetic problem, but it can also produce pain, limp, and early degenerative arthritis. An assessment of lower extremity alignment, including its location and magnitude of deformity, can be achieved via mal-alignment test and mal-orientation test, using a lower extremity standing full-length radiography. Proper evaluation allows the surgeon to determine an effective treatment plan for deformity correction.

Operative Treatment of Pediatric Distal Forearm Bothbone Fracture: Sang Uk Lee, Changhoon Jeong, Il Jung Park, Jaeyoung Lee, Seman Oh, Kyung Hoon Lee, Sanghyun Jeon; J Korean Fract Soc 2015;28(4):237-244. Published online October 31, 2015; DOI: https://doi.org/10.12671/jkfs.2015.28.4.237

Abstract PDF: PURPOSE
Pediatric patients with distal forearm bothbone fractures of surgical indication were treated with the Kapandji reduction technique for radius and flexible intramedullary nail for ulna at our institution. The purpose of this study is to evaluate clinical and radiological results.
MATERIALS AND METHODS
From February 2012 to June 2014, we retrospectively evaluated 16 out of 18 cases with distal forearm bothbone fractures treated with the Kapandji reduction technique for radius and flexible intramedullary nail for ulna with at least 1-year follow-up. The average age at operation was 9.1 years (7-13 years).
RESULTS
Adequate reduction for both radius and ulna was achieved for all cases, and none of the cases showed re-displacement until the last follow-up. Mean 6.6 weeks lapsed until bony union was observed for the radius. For the ulna, the mean was 6.5 weeks. All patients gained full wrist range of motion at the last visit.
CONCLUSION
For pediatric distal forearm bothbone fractures, intrafocal Kapandji reduction and internal fixation with Kirschner wire for radius and reduction and internal fixation with a flexible intramedullary nail for ulna is the technique for handy reduction. Use of this technique can prevent re-displacement during the union process and achieve excellent clinical and radiologic results.

Free Vascularized Fibular Grafts for Treatment of Infected Nonunion of the Tibia: Hyoung Min Kim, Il Jung Park, Youn Soo Kim, Kee Haeng Lee, Chan Woong Moon, In Ho Jeong, Changhoon Jeong; J Korean Fract Soc 2006;19(2):163-169. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.163

Abstract

PURPOSE
To analyze the result of free vascularized fibular grafting for treatment of infected nonunion of the tibia with radical bone and soft tissue defect.
MATERIALS AND METHODS
17 patients with infected nonunion of the tibia who underwent a reconstruction using free vascularized fibular grafting were reviewed retrospectively. The mean follow-up period was 70.3 months. We analyzed the results radiographically which included the time of bone union, the amount of hypertrophy of grafted bone and complications.
RESULTS
The average length of bone defect was 8.8 cm (5~15 cm), and the average length of fibular graft was 14.1 cm (10~17.5 cm). Bony union was achieved in 11 of 17 cases and the average time of bone union was 5.2 months (4~6 months). There were 6 cases of nonunion. All nonunions developed at the proximal end of graft in patients who underwent fixation using pin and external fixator. Union was eventually achieved in all cases in 6.0 months (5~8 months) after the cancellous bone graft and plate internal fixation. Hypertrophy of grafted bones with more than 20% developed only in 4 cases out of 17. There were 3 cases of stress fracture, however there was no recurrence of infection or serious donor site morbidity.
CONCLUSION
Free vascularized fibula grafting is one of the most effective reconstruction options for the infected nonunion of the tibia with radical bone and soft tissue defect. Strong internal fixation using plate and screws is required to reduce the rate of nonunion and stress fracture of grafted fibulas.
