Analysis and Clinical Study on Fracture Dislocation of the Talus: Ye Yeon Won, Chang Hoon Jeon, Jae In Ahn, Seung Jun Choi, Jung Mo Lee; J Korean Soc Fract 2000;13(2):382-389. Published online April 30, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.2.382

Abstract PDF: PURPOSE
: Talar fractures are uncommon and so surgeon's experience in the treatment of the talar fracture is limited. This study was undertaken to evaluate the incidence, associated injuries, complications of talar fracture and results of treatment.
MATERIALS AND METHODS
: Authors experienced 15 cases of the talar fractures treated at Ajou university Hospital from 1995 to 1998 with minimal 1 year follow-up period and obtained following result.
RESULTS
: Of 15 cases, fall down injury was the most common cause of injury(11/15). 4 ipsilateral medial malleolar fractures, 2 lateral malleolar fractures and other associated injury was occured. According to the Hawkins' classification 5 cases in type I , 1 cases in typeII, 2 cases in typeIII were observed. 2 posttraumatic arthritis, 1 skin necrosis, 1 avascular necrosis, were observed as complications but nonunion was not observed.
CONCLUSIONS
: We suggest that early and accurate anatomical reduction and rigid internal fixation of the fracture dislocation of the talus canprevent complications such as acascular necrosis, posttraumatic arthritis.

Predictors for saving the limb after popliteal artery injury: Byoung Suck Kim, Woo Sig Kim, Byoung Hynn Min, Chang Hoon Jeon, Ye Yeon Won, Dae Woong Kim, Jae In Ahn; J Korean Soc Fract 1999;12(4):879-884. Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.879

Abstract PDF: PURPOSE
: This study had been performed to evaluate the factors affecting either saving the limb or amputation after popliteal artery injury associated with fractures or dislocation around the knee.
MATERIALS and METHODS
: Twelve patients of popliteal artery injury were included. Authors had analysed nine probable factors as follows - age, sex, injury mechanisms, injury types, interval between injury and time to arrive at the hospital, interval between injury and time of operation, surgical methods for revascularization, severity of extremity injuries and fasciotomy, for discrimination between the limb-saving group and the amputation.
RESULTS
Ten patients were arrived at the hospital within 48 hours after the injury. Each patient was managed by end-to-end anastomosis in 6 cases and autogenous vein graft in 4 cases and among them, 2 cases needed additional amputation for vascular compromise. All limbs could be saved in which cases operate within 6 hours after the injury. However, the limb was lost in one of 6 cases(16.7%) between 6 and 20 hours, in one of two cases(50%) over 20 hours. One of 7 cases(14.3%) with the Mangled Extremity Severity Score(MESS) of 2 to 4 points, two of 4 cases(50%) with MESS of 5 to 6 points and one(100%) with MESS of 7 points were amputated. All 4 patients associated with fasciotomy could save their limbs, however, two of 6 patients not associated with fasciotomy lost. SUMMARY : Authors thought the most reliable predictors for saving the limbs after the popliteal artery injury might include the MESS and fasciotomy, however, ischemic time more than 6 hours might not be an absolute indication for amputation.

Pelvic Bone Fractures in Children: Byoung Suck Kim, Ye Yeon Won, Weon Ik Lee, Myeong Ryeol Song, Jae In Ahn; J Korean Soc Fract 1998;11(1):107-114. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.107

Abstract PDF: The pelvic bone fractures in children were uncommon, except for avulsion injuries in the literature and authors had 21 cases of children's pelvic bone fracture, ranging from 1 to 15 years. The mode of injury, type of fracture, associated injuries, morbidity and mortality, and out-come were retrospectively analyzed. The majority of injuries were from automobile-pedestrian collisions (81.0%). the Torode and Zieg type IV injury had the greatest morbidity, mortality, and complications. sixteen patients had non-orthopedic, associated injuries and fourteen required blood transfusions within initial 48 hours after injury. Two of them passed away due to hematologic unstableness. Twenty patients were managed by conservative method, except for one operative case by using of an external fixation device. This study included only 13 cases had average 1 year of follow-up. One acetabular dysplasia of 5 acetabular fractures was found at 12 months after injury. The nonoperative approach for the pelvic bone injury has had a satisfactory outcome in our hospital. so, authors think that if conservative methods will be properly applied, it may be one of the methods of treatment for the children's pelvic bone fracture. Even though there is no symptoms, long-term follow-up will be inevitable for checking more severe acetabular dysplasia and leg length discrepancy.

Extra-articulaf Fracture of Proximal Tibia: Heui Jeon Park, Jae In Ahn; J Korean Soc Fract 1990;3(2):232-237. Published online November 30, 1990; DOI: https://doi.org/10.12671/jksf.1990.3.2.232

Abstract PDF

Twenty-nine cases of the proximal tibial metaphyseal fractures(extra-articular) treated at the Department of Orthopaedics, Wonju Christian Hospital from January 1982 to December 1989 were studied in clinical and radiological aspects. The results were as follows: 1. The main cause of the fractures was the traffic accident, 19 cases (65.6%). 2. The most common type of the fractures was transverse fracture, 18 cases (62%). 3. The average time required for fracture union was 18 weeks in the conservative treatment group, 16 weeks in the surgical treatment group. 4. In the union time of the fracture, operative treatment was shorter than closed treatment. 5. The incidence of complication was relatively high in conservative treated group, 7 cases (21%).

Complication Folloing Operative Treatment in Complete Acromioclavicular Joint Dislocation: Sung Kwan Hwang, Jae In Ahn, Heui Jeon Park, Zi Hoan Cha; J Korean Soc Fract 1988;1(1):64-70. Published online November 30, 1988; DOI: https://doi.org/10.12671/jksf.1988.1.1.64

Abstract PDF: The conservative treatment such as plinting, bandaging and harnessing in the partial disrupton of the acromioclavicular joint(Grade II or less) has been successuful, but many surgeons prefer to operative treaments for complete A-C dislocation(Grade III). Though more than 55 operative methods of treatment were reported in the literature, they could be divided into four categories: 1) acromioclar reduction and acromioclavicular fixation, 2) acromicoclavicular reduction, coracoclavicular ligament repair, and coracoclavicular fixation, 3) distal clavicle excision, and 4) muscle transfers. Among numerous operative methods, we used Weaver-Dunn technic, A-O tension Band technic, and Modified bosworth technic in total 28 cases of complete A-C dislocation from March 1984 to June 1988 at the Yonsei University Wonju College of Medicine, Wonju Christian Hospital. In most cases, excellent or good results were obtained, but we stillfound swveral postperative complications. We experienced neither deep wound infection nor osteomyelitis. All 6 cases had fixation-related complications. After close examination of operation notes and X-rays, following suggestions were considered. 1. Reduce every A-C joint anatomically before inserting K-wires through A-C joints. 2. Start shoulder motion several days after operation to provide enough time form healing of deltoid and trapezius muscles. 3. Surgenous play a major role to prevent commplications such as malposition of fixatives and incomplete A-C joint reduction
