PURPOSE
The purpose of this study was to determine the results of internal fixation with locking plate system for the unstable proximal humerus fracture.
MATERIALS AND METHODS
Sixteen cases of unstable proximal humerus fracture were treated using locking plate system between September 2004 and June 2005. Average age of the patients was 55.6 years (range, 22 to 78), male was four patients, female was twelve. The clinical outcomes were evaluated by using Neer's evaluation criteria and Constant socring system. We analyzed the radiological results by bony union time and Paavolainen method. All data was analyzed statistically.
RESULTS
According to Neer's evaluation ciriteria, eleven cases (69%) showed excellent or satisfactory results and according to Constant scoring system, twelve cases (75%) showed excellent or good result. Twelve cases (75%) showed good results by Paavolainen method. In all cases, bony union was obtained in average 12.8 weeks after operation. There were two complications; one screw irritation and one screw loosing.
CONCLUSION
The patients treated using locking proximal humerus plate could exercise earlier due to good initial stability. And the clinical and radiological results were relatively good. The treatment of unstable proximal humerus fracture with locking plate system was considered as a good method.

The Fate of Large Butterfly Fragments in Femoral Shaft Comminuted Fractures Treated withClosed Interlocking Intramedullary Nailing: Keun Bae Lee, Jae Yoon Chung, Eun Sun Moon, Eun Kyoo Song, Kwang Cheul Jeong; J Korean Soc Fract 2002;15(4):504-510. Published online October 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.4.504

Abstract PDF: PURPOSE
To evaluate the radiographic changes and union of large butterfly fragments after closed interlocking IM nailing for femoral shaft comminuted fractures.
MATERIALS AND METHODS
The objects of this study were 23 cases(15 males, 8 females) of femoral shaft comminuted fractures with butterfly fragments larger than 5cm and with the follow up period of 12 months or more from June 1995 to June 2000. We assessed the size, the degrees of displacement and angulation of the large butterfly fragments at preoperatively, one day, one month and three month postoperatively and evaluated the union at four month and six month postoperatively.
RESULTS
The size of the fragments was 8.4cm (5.0-13.0) in average. The distance between the fragment and shaft was 15.9cm preoperatively and 10.1, 7.7, 6.8cm at one day, one month and three month postoperatively. In 13 cases of angulation over 5 degrees, it changed from 19.6 degrees preoperatively to 13.9 degrees , 8.4 degrees , 5 . 9 degrees at one day, one month and three month postoperatively. There is no increase in angulation.The union was completed at 4 months in 13 cases (56.5%) and at 6 months in all except one case of delayed union, in which we did not do any further procedure until the union was achieved.
CONCLUSION
In femoral shaft comminuted fractures with displaced large butterfly fragments treated with closed interlocking IM nailing, the distance and angulation of fragments decreased gradually and even the fragments were inverted or largely displaced and angulated the fragments were united. So the caution must be given not to displace the fragments intraoperatively and to keep anatomical position of the fragments by active exercise and hydrostatic pressure of the muscles of thigh postoperatively. Then the open reduction and internal fixations of the fragments will not be necessary.

Use of Cancellous Bone Allograft in the Treatment of Long bone Fractures: Keun Bae Lee, Taek Rim Yoon, Jae Yoon Chung, Sung Taek Jung, Jae Joon Lee; J Korean Soc Fract 2001;14(4):776-782. Published online October 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.4.776

Abstract PDF

PURPOSE
The goal of our study was to evaluate the usefulness of frozen cancellous bone allograft in the treatment of long bone fractures that had bone defect and nonunion.
MATERIALS AND METHODS
22 cases of long bone fractures(femur and tibia) with severe comminution or bone defect and nonunion were treated by operation using frozen cancellous bone allograft from March 1998 through May 2000. Thirteen were male and nine were female. The average age was 55 years old (range, 17-76 years) and the mean duration of follow-up was 20.1 months(range, 10-37 months). Eleven cases were femoral fractures, 7 cases of tibial fractures, and 4 cases of nonunion. Allografts were achieved from the patients of femoral neck fracture or osteoarthritis of the hip, and cadaveric donors. The specimens were carefully evaluated based on medical history and laboratory examination about the acute or chronic infection, and bloodtransmitted diseases. The results were evaluated by clinically, such as infection, pain at fracture site, immunological rejection and by radiologically union or resorption of allografts.
RESULTS
Radiologically, bone union was obtained in 14 cases(63.6%) at 6 months after operation, in all except two cases(90.9%) at 9 months after operation. Clinically, pain at fracture site, infection, and immunologic rejection were not observed.
CONCLUSION
In the treatment of severe comminuted fracture or nonunion of long bones, cancellous allograft transplantation after strict donor selection and appropriate screening was a good substitution for autograft avoiding of donor site morbidity or limitation in quantity.

Cervical Spine Fractures in Ankylosing Spondylitis : A case Report: Jae Yoon Chung, Jung Pil Heo, Hyong Yeon Seo; J Korean Soc Fract 1997;10(1):175-179. Published online January 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.1.175

Abstract PDF: The patient with ankylosing spondylitis is easily apt to be fractured in spine regions, even by minor trauma due to severe limitation of spinal motion and progressive osteoporosis. In those patients, accurate reduction and rigid internal or external immobilization and postoperative early mobilization is very important to treat or prevent the spinal cord injury. Untill now halo-vest immobilization or posterior fusion is widely accepted method of treatment and there was no report about anterior plate fixation. Authors fused the patient anterorily with tricortical iliac graft and plate with compression mechanism to get early solid bony union, to increase the immediate rigid stability, to correct the deformity and to mobilize the patient early as possible. We have experienced a 54-year-old male patient with ankylosing spondylitis complicating traumatic fracture of the cervical spine at C6-7 and follow up study of 9 years was possible. The patient was injured by minor pedestrian motor vehicle accident. Pre-injury activity was normal, and neurological status was Frankel grade D just after trauma however, it was aggrevated to Frankel grade C paraplegia during position change before operation. The patient was anesthesized with aid of the tracheostomy. Anterior plate fixation was performed with tricortical iliac suut bone graft and plate. And then early mobilization was encouraged with SOMI brace. Neurological status was improved and there was no peri- and post-operative complications. Systemic complications was not occured also. Re-displacement at fracture site with minimal screw loosening during follow up period was observed however, solid bony union was obtained at post-operative 3 months without further displacement or loosening. We report this case with review of literatures for good clinical result of anterior fusion with plate during long term follow up period of 9 years.

Result of the Transpedicular Zielk Instumentation for the Fractures and Dislocation of the Thoracic and Lumbar Spine: Jae Yoon Chung, Hyung Soon Kim, Go Hun Chung; J Korean Soc Fract 1990;3(2):268-274. Published online November 30, 1990; DOI: https://doi.org/10.12671/jksf.1990.3.2.268

Abstract PDF: For the evaluation of the clinical and radiological results of transpedicular Zielke instrumentation for the fractures and dislocations in the thoracic and lumbar spine, the authors analysed the 13 patients who were operated by that method and were followed up more than one year after operation (Av 33 months). 1. Operative indications were seat belt type, flexion-distraction injury of fracture-dislocation type and burst type that needed additional stabilization after anterior fusion. 2. Extent of fixation and fusion were 1 motion segment in 6, 2 motion segment in 7. 3. Bony union could be observed within 6 months in all, without any possible complications of metal failure, non-union, loss of correction or neural damage. 4. Kyphotic angular deformity were changed from 25 preoperatively, to 3 post-operatively and 5 at the end of follow up. 5. anterior vertebral height in 6 burst type were 46% preoperatively, 77% post-operatively and 74% at the and of follow up. From above results, the authors concluded that the transpedicular Zielke instrumentation enabled the fixation of shortest segments and provided enough stability when the method was applied in the types of injury that demand posterior compression for the reduction and stabilization of the deformity and instability.
