Clinical Applications of Autologous Cultured Osteoblasts: Case Report: Seok Jung Kim, In Young Ok, Cheong Ho Chang, Young Sik Kim, Jae Deog Jang, Won Jong Bahk, Joo Hyung Lee; J Korean Fract Soc 2004;17(2):197-201. Published online April 30, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.2.197

Abstract PDF: We treated 3 cases of fracture and 1 case of avascular necrosis of femoral head using autologous cultured osteoblasts injection. The stromal cells from the bone marrow were cultured to differentiate to osteoblasts for 4 weeks. The fracture sites of each patients were right ulnar shaft, left radial shaft, and left 5th metatarsal base. All of the fractures showed callus formations after 1 week of osteoblasts injection to the fracture site. After 4 weeks, callus formations were progressed. Avascular necrosis of femoral head was bilateral and both were Ficat stage II. Core decompression and allograft impaction were performed to the left, and core decompression and autologous cultured osteoblasts injection percutaneously after 4 weeks of the decompression operation were done to the right femoral head. CT images of 1 year from the operations showed trabecular bone formation and well maintained femoral head contour of the right femur, but resorption of the grafted bone for the left.

Stress Fracture of the Femoral shaft: Sung Ho Hahn, Bo Kyu Yang, Seung Rim Yi, Shun Wook Chung, Hyoung Sik Kim; J Korean Soc Fract 2001;14(2):200-207. Published online April 30, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.2.200

Abstract PDF: PURPOSE
This study was evaluated to find the aspect of the femoral shaft stress fracture. MATERIAL AND METHOD: From Jan. 1990 to May. 1999, this study included 8 cases diagnosed as stress fracture of the femoral shaft that were proved by clinical & radiologic findings in our hospital. Patients with undisplaced femoral shaft stress fracture were treated conservatively and patients with displaced ones were treated with open reduction and internal fixation.
RESULT
5 of 8 fractures were located in the distal shaft and 3 were in the middle shaft. 5 of 8 fractures were undisplaced and 3 were displaced. These 3 displaced fractures were located in the distal shaft.
CONCLUSION
According to our experience, femoral distal shaft stress fracture which is rare, has a high tendency to displace. Therefore, the early diagnosis and prevention of femoral distal shaft fracture is important to prevent progression to displaced fracture.

Operative Treatment of the Capitellar Fracture of the Humerus: Ho Jung Kang, Sang Jin Shin, Hyoung Sik Kim, Eung Shick Kang; J Korean Soc Fract 2000;13(3):584-590. Published online July 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.3.584

Abstract PDF: PURPOSE
The capitellar fractures of the humerus are rare. Furthermore, the treatment of the fracture has been controversial. This study presents the experience in the operative treatment of capitellar fractures of the humerus.
MATERIALS AND METHODS
Eleven patients with an average age of 41.0 years (range, 15-76 years) were included in this study. The average length of follow-up was 13.6 months (range, 12-17 months). Type I fracture was noticed in ten patients and type III in one patient. Herbert screws, Kirschner wires, cancellous screw and miniscrew were used for internal fixation. The postoperative immobilization period averaged 6.7 days (range, 3-10 days).
RESULTS
Flexion of the elbow averaged 135 degrees (range, 100-150 degrees), with an average flexion contracture of 17 degrees (range, 5-45 degrees). Supination averaged 83 degrees (range, 20-90 degrees) and pronation averaged 87 degrees (range, 80-90 degrees). Seven patients had an excellent functional results, two good and two fair according to Broberg and Morrey elbow-rating scale. The complications included loosening of Kirschner's wires in two patients, osteochondral loose body in one, nonunion and heterotopic ossification in one and severe limitation of motion in one.
CONCLUSION
The early motion of the elbow joint after anatomical reduction and internal fixation for the displaced capitellar fracture is an effective treatment in restoring normal elbow function.
