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.

Meniscal Injuries with Tibial Plateau Fractures: Yong In, Won Jong Bahk, Oh Soo Kwon, Chae Gwan Kong, Ju Young Kim; J Korean Soc Fract 2003;16(4):490-495. Published online October 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.4.490

Abstract PDF: PURPOSE
The purpose of this study is to evaluate by arthroscopy the incidence of meniscal injury and the result of its treatment in fractures of the tibial plateau.
MATERIALS AND METHODS
From March 2000 to July 2002, twenty-three patients with tibial plateau fractures were examined and treated by arthroscopy before reduction of the fractures. Following the classification by Schatzker, there were 3 pure cleavage fractures (type I), 7 with cleavage and depression (type II), 4 with pure central depression (type III), one medial condyle fracture (type IV) and 8 with meta-diaphyseal fractures (type VI). Meniscal injuries were treated by meniscectomy or meniscal repair. Second look arthroscopy for patients treated with meniscal repair were performed at 6 months after operation or at time of the fixative removal.
RESULTS
Thirteen knees (56%) were found to have meniscal injuries. There were 11 lateral meniscal tears, eight of which were periphral and repaired. There were 3 complex lateral meniscal tears which required partial meniscectomy. The five medial meniscal tears were required all partial meniscectomy. Six of the eight patients who were repaired the meniscal tears evaluated by second look arthroscopy. Five patient showed complete healing and one showed incomplete healing.
CONCLUSION
Every effort should be made to repair the meniscal tears in tibial plateau fractures.

Operative Treatment of Forearm Fractures in Children: Nam Gee Lee, Seung Ki Kim, Won Jong Bahk, Hyun Joon Song, Ban Chang; J Korean Soc Fract 1997;10(1):195-202. Published online January 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.1.195

Abstract PDF: Management of severe diaphyseal fracture of radius and ulna in children can be a challenging problem. Reduction and maintenance of the position of two mobile parallel bones is difficult because pronating and supinating muscles produce angulatory as well as rotational forces. Open reduction and internal fixation are generally accepted for adult forearm fractures, but controversy surrounds open reduction for children. What should be done for the irreducible fracture that will result in a malunion? Several authors advocate open reduction in children over 10 years of age rather than accept poor position. And others advocate open reduction regardless of age if closed reduction is unsatisfactory. We reviewed thirteen children between 6-14 years of age, who had irreducible fractures of diaphysis of forearm both bone, and who were treated with open reduction and internal fixation with plate for mid 1/3 fractures(4 cases) and open reduction and internal fixation with K-wires for distal 1/3 fractures(9 cases). The results were as follows; 1. 2 cases(15%) had limitation of pronation within 10 comparing with uninjured side. But 11 cases(85%) had equal movements on both sides. And the range of motions of the elbow and wrist are within normal limit. 2. More than 20 angulation for mid 1/3 fracture over 10 years of age, and more than 20 angulation or 20% displacement for distal 1/3 fracture over 6 years of age, it would be better to perform a surgical treatment if nonsurgical treatment was failed. 3. Immobilization periods were 5 weeks for plate fixation group and 6.9 weeks for K-wire fixatioin group. Bone union was occurred in all cases, at 9 weeks in plate fixation group and 8 weeks in K-wire fixation group. 4. Its better to fix with plate ofr promimal 2/3 fracture and K-wire for distal 1/3 fracture in case of operation. In conclusion, our results of open reduction and internal fixation were satisfactory if adequate alignment of fractures had not been achieved or maintained.

Lunate dislocation and perilunte dislocation with or without fracture: Won Jong Bahk, Jong Min Sohn, Nam Gee Lee, Seung Key Kim, Young Joo Park, Han Chang; J Korean Soc Fract 1996;9(1):42-49. Published online January 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.1.42

Abstract PDF: The lnate dislocation and perilunte dislocation with or without fracture, occupying about 10% of carpal injury, might b classified as a same category of injury resulted from similar mechanim. Initial diagnosis was missed often. In case of failure of closed reduction, open reduction and internal fixation will be necessary. The authors analyzed retrospectively 15 patients with lunate dislocation and perilunate dislication without fracture(Group A)and perlunate dislication with scaphoid fracture(Group B) who were treated from 1989 to 1994 at our hespital. The follow-up periods were 7 months to 60 months with mean of 23.2 months. The results were as follows. 1.Group A were 2 cases of anterior dislication of lunate and 8 cases of perilunate dislocation Group B were 5 cases of transscaphoid perilunate fracture-dislocation. The direction of perilunar dislocation with or without scaphoid fracture was posterior in all cases. 2.The causes of injury were fall from height in 7 cases, slip in 3 cases, traffic accident in 3 cases and crushing injury in 2 cases. 3.The overall clinical results by modified Green and OBriens clinical score were excellent in 4 cases(26.7%), good in 4 cases (26.7%),fair in 4 cases(26.7)and poor in 3 cases(20%). 4.9 out of 10 cases (90%) in Group A and 3 out of 5 cases(60%) in Group B were superior to fair. Early treatment within 3 days injury was performed in 11 cases (7 in Group A,4 in Group B), The average point was 85 and 70, respectively and there was no statisticat significance between two groups(P>0.05). Treatment was delayed beyond two weeks after injury due to missed initial diagnosis and open wound in 4 cases(3 in Group A,1 in Grdup B). The final tesults were 1 case of good, 1 case of fair, 1 case of poor in Group a, and 1 case of poor in Group B. There was no statistical significance between the early treatment cases and delayed treatment cases(P>0.05). In conclusion, ounate and perilunate dislocation without scaphoid fracture can be treated by early operation to get and maintain the anatomical reduction. The authors thought that the presence of scaphoid fracture, nonanatomic reduction and delay in treatment are poor prognostic factors.

Complications and Its Treatment of Ankle Fractures: In Kim, Seung Ko Rhee, Soon Yong Kwon, Ki Won Kim, Yong Keun Cho, Han Chang, Won Jong Bahk, Nam Kee Lee, Seung Ki Kim; J Korean Soc Fract 1995;8(4):736-746. Published online October 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.4.736

Abstract PDF: We have investigated total 294 cases of ankle fractures, which were treated and followed for average 17 months after treatment at St. Marys hospital since 1980, to detect the complications and to define their provoking factors. The results were as follows; 1. Twenty-six cases out of total 294 cases of ankle fracture(8.8%) were complicated clinically and radiologically. 2. Their complications are osteoarthritis(8/26, 31%), diastasis of distal tibio-fibular syndesmosis(9/26, 34.6%), varus ankle deformity(5/26, 19.2%), malunion(6/26, 23%), non-union and ankle instability(each 2/26, 7.7%) in its order, but 14 cases of the 26 cases complained painful limited ankle motion and limp. So, clinical symptoms are not closely related with radiologic changes in complications of ankle fracture. 3. The complications are common in elderly patients over 50 of their ages(12.26, 46%) and in younger patients under 16 of their ages(5/26, 20%). 4. The complications are frequently found in pronation-external rotation injuries(6/61, 1O%), pronation-dorsiflexion(9/14, 64%) and supination-external rotation injuries(8/165, 4.8%) in orders. 5. Malpractice with misuse of instrument(12/26, 46%), mistakes in preoperative evaluation and neglect any ankle fracture or diastasis of syndesmosis(8/26, 30.7%) and severity of injuries(6.26, 23%) are common causes of complications of ankle fractures. 6. Varus ankle deformity due to early epiphyseal closure are shown in 5 cases(5/28, 20%) and three of them are treated with supramalleolar corrective osteotomies and Langenskiolds physolysis In conclusion, the complications of ankle fracture could be reduced by accurate pre-operative evaluation to detect the hidden soft tissue injuries or fracture mechanism and by also anatomic reduction, rigid internal fixation and early ankle motions. childrens ankle fracture will induce angular deformity and limb length discrepancy due to frequent epjphyseal damage, so long-term follow up should be kept in mind until their skeletal growth are ceased.
