The Relationship between the Variation of the femoral neckshaft angle according to Age and the Fracture of the Hip: Jun Seop Jahng, Seong Hwan Moon, Jin Ho Che; J Korean Soc Fract 2000;13(4):702-708. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.702

Abstract PDF: PURPOSE
Femur neck-shaft angles were obtained from plain radiographs of the pelvis and their changes according to age were assessed along with their correlations to hip fracture incidence.
MATERIALS AND METHODS
Forty-four patients who have received surgical treatments for femur neck or intertrochanteric fractures and 171 patients who performed bone densitometry at out patient clinic without any history of hip fractures were included in the study. All patients were older than 50 years. Standard value of 0.725 g/cm2 w a s used to separate the osteoporosis and non-osteoporosis groups. Femur neck-shaft angle was measured from standardized radiograph.
RESULTS
In the non-osteoporosis group, varization of femur neck-shaft angle was observed as age increased. No significant difference of the neck-shaft angle was proven between osteoporosis and non-osteoporosis group, and no correlation existed between the femoral neck bone mineral density and neck-shaft angle. Furthermore, fracture group and no fracture group showed no significant difference in neck-shaft angle.
CONCLUSION
The decrease in the neck-shaft angle with age increments has no effects on incidence of hip fracuture and factor most closely associated with fractures is bone mineral density.

Treatment of Intraarticular Fractures of the Distal Radius with Dynamic External Fixator: Myung Ku Kim, Nam Hong Choi, Jun Seop Jahng, Hyoung Kook Ahn; J Korean Soc Fract 1995;8(3):688-695. Published online July 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.3.688

Abstract PDF: The treatment of intra articular fractures of distal radius is difRcult and has various problems. Over the past few years, the importance of alignment correction, preservation of normal radial length and reconstruction of congruity of both radiocarpal and radioulna joints have been emphasized. The end redults of closed reduction and rigid fixation with dynamic external flxator include 13 cases(86.6%) with excellent and good results. Roentgenograms of 15 of these patient show accurate alignment of the healed fractures. One patient had a poor functional result although roentgenograms demonstrated good alignment of the healed fractures. The dynamic external fixator is both a useful and convenient method for the reconstruction and treatment of comminuted intraaricular fractures of the distal radius.

Femoral Shaft Fracture Associated with Ipsilateral Femoral Neck or Intertrochanteric Fracture: Kyoo Ho Shin, Yun Pei Kung, Jun Seop Jahng; J Korean Soc Fract 1995;8(3):480-487. Published online July 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.3.480

Abstract PDF: The segmental fracture of the femur usually was caused by severe force and often accompanied with marked damage of the soft tissue and associated fractures of the other bones. Treatment of the segmental fracture is almost always required operation, and the interest lies in deciding on what operating methods to use and the technical difficulty involed with each method. From Jan. 1986 to Dec. 1993, 29 patients were treated for femoral neck or intertrochanteric fractures which accompanied with ipsilateral femoral shaft fractures at Severance Hospital, Yonsei University College of Medicine, 16 cases were intracapsular (femoral neck) and 13 cases were extracapsular (intertrochanter) hip fractures. We analysed the union time and complications of the 21 cases which were followed over one year. The following results were obtained: 1. For the group of ipsilateral femoral neck and shaft fracture, the knee injury was the most common associated injury (66.7%). 2. For the group of ipsilateral intertrochanter and femoral shaft fracture, the knee injury was not so frequent than the previous group (11.1 to). 3. The ipsilateral femoral neck and shaft fracture was induced by a longitudinal force, which was parallel with femoral shaft and through the knee, and accompanied with a lateral force. But the ipsilateral intertrochanter and femoral shaft fracture may be induced by a different mechanism, a direct transverse force towards the proximal femur. In conclusion. the ipsilateral intertrochanteric and femoral shaft fracture should be distinguished from the ipsilateral femoral neck and shaft fracture, because of the associated injury pattern and different mechanism of the injury.

A Clinical Study of Ankle Diastasis with Fracture of flbula: Koon Soon Kang, Jun Seop Jahng, Hui Wan Park, Ho Jung Kang, Young Chul Cho; J Korean Soc Fract 1994;7(2):388-396. Published online November 30, 1994; DOI: https://doi.org/10.12671/jksf.1994.7.2.388

Abstract PDF: Ankle joint is important as a weight-bearing joint and ankle diastasis requires accurate diagnosis and treatment. The authors analysed 82 cases of ankle diastasis with fibular fracture during the year 1986 through 1992 at YoungDong Severance Hospital. The results obtained are as follows. 1. The most common cause of injury was slip down, and traffic accident and fall down in order. 2. By Weber classification, 42 cases were type BS(+) and 40 cases were type C. By Lauge-Hansen classification, supination-external rotation was most common (35 cases). 3. Open reduction was done in all cases for fracture of fibula. 45 cases of ankle diastasis were treated with one transfixation screw and 37 cases without transfixation after confirmation by Cotton test. 4. The result according to Cottons criteria, 39 cases(86.7%) were were good or fair in transfixation group, and 34 cases(91.9%) in nontransfixation group. In conclusion, the transfixation screw was not necessary in cases of ankle diastasis which was considered as stable by Cotton test after internal fixation for the fracture of fibula.

Abstract PDF: The Os Calcis is the largest bone of the tarsal bones. The incidence of fracture of the calcaneus is more frequent than that of any other tarsal bones. Farctures involving subtalar joint can usually cause serious and persistent disabilities and badly influence the patients psychologically, socially and economically. But, there was no standardized treatment method for these fractures. The purpose of this article is to describe the surgical technique and the results obtained in 33 consecutive cases of calcaneal fractures involving the subtalar joint. The results were as follows, 1. Of 33 patients, 24 patients were male and 9 patients were female. 2. The main cause of fracture of calcaneus was a fall from a height in 79% of cases. Most of the associated fractures were the spinal and tibial fractures. 3. Of these intra-articular fractures, 19 fractures were joint depression type and 14 cases were tongue type by Essex-Lopresti classification. 4. Open reduction and internal fixation was performed in 18 cases of joint depression type and 6 cases of tongue type, and closed reduction and axial pinning was performed in 8 cases of tongue type and 1 case of joint depression type. 5. After average twenty-two months follow-up, the over all results of open reduction and internal fixation were excellent and good in 71%, and that of closed reduction and axial pinning were excellent and good in 67% by Salama creteria. 6. Complications included four superficial wound infection and one subluxation of peroneal tendon.

Avulsion Fractures of the Tibial Tuberosity: Three Cases Reports: Ho Jung Kang, Koon Soon Kang, Jun Seop Jahng, Young June Park; J Korean Soc Fract 1992;5(2):372-377. Published online November 30, 1992; DOI: https://doi.org/10.12671/jksf.1992.5.2.372

Abstract PDF: The talus is a important bone because it supports and distributes the body forces above it. Avulslon Fractures of the tibial tubercle prior to epiphyseal closure are uncommon. Fractures that are seen most frequently in adolescents. Watson-Jones classified these injuries into three types. The authors treated three cases of the tuberosity fractures. Two adolescent boys were treated with open reduction and screw fixation and K-wire fixation. One adult man was treated with open reduction and circumferential wire fixation. The Osgood-schlatter disease was diagnosed in two patients. There were small flecks of calcification 3 to 4cm proximal to the tubercle in the two adolescent cases. Functional motion was started within six weaks after operation. No early complications occurred, and no later defermities. such as genu recurvatum as reported by Blount, were detected. All patients returned to normal activity in one year after an operation.

Dislocation of Fifth Carpornetacarpal Joint: Two Cases Report: Jun Seop Jahng, Hui Wan Park, Kyu Hyun Yang, Chang Hoon Jeon; J Korean Soc Fract 1990;3(2):275-279. Published online November 30, 1990; DOI: https://doi.org/10.12671/jksf.1990.3.2.275

Abstract PDF

Dislocation of fifth carpometacarpal joint is an unusual injury. In First case, traumatic dislocation of fifth carpometacarpal joint, fracture of the shaft of fourth metacarpal bone and hamate were present. The diagnosis of dislocation of fifth carpometacarpal joint was missed initially. In second case, there was only dislocation of 5th CMC joint. In these cases, we treated the dislocation of fifth carpometacarpal joint with percutaneous K-wire fixation and short arm splint immobilization.

A Clinical Study on the Supracondylar and Intercondylar Fractures of the Femur: Koon Soon Kang, Jun Seop Jahng, Hui Wan Park, Kyu Hyun Yang, Seok Joo Moon; J Korean Soc Fract 1990;3(2):170-179. Published online November 30, 1990; DOI: https://doi.org/10.12671/jksf.1990.3.2.170

Abstract PDF: The fractures of the supracondylar and intercondylar region of the femur are difficult to manage because of the wide range of potential complications. Most studied over the past twenty years have attempted to compare the results of nonsurgical with those of surgical methods. The new fixation divices and techniques were developed. The accurate anatomical reduction, rigid internal fixation, and early motion of joint have more improved results of the treatments than past. The following clinical results were shown by analsis of 18 cases of supracondylar and intercondylar fractures of the femur treated in the Department of Orthopedic Surgery, Yonsei University, College of Medicine during the past 6 years from Jan. 1983 to Dec. 1988. 1. The prevalent age distribution was between 41 and 50 years of age(33.3%) and the ratio between male and female was 1.3:1. The most common cause of injury was traffic accidents(66.7%). 2. A classification of supracondylar and intercondylar fractures was divided according to ASIF classification, and the most common type was C2(55.5%). 3. Thirteen patients(72.2%) were associated with injuries of other parts and the most frequent associated fracture was tibial fracture and the most common associated other injury was cerbral consussion or contusion. 4. The satisfactory(excellent or goo) result of surgical treatment(14 cases) and conservative treatment(4 cases) was equal(50.0%). But severity of injury of conservative treatment group was milder than surgical treatment group. 5. Complications were deep infection of 2 cases(11%), delayed and nonunion of 4 cases (22%), Knee joint siffness below 90 rnage of motion of 8 cses(44.4%). 6. Finally, good results of treatment depend largely on early accurate anatomical reduction, rigid internal fixation, early joint motion.

A Clinical Study of Femoral Neck Fracture Over Age of 50 Years: Hui Wan Park, Jun Seop Jahng, Koon Soon Kang, Kyung Hoon Kang; J Korean Soc Fract 1988;1(1):76-85. Published online November 30, 1988; DOI: https://doi.org/10.12671/jksf.1988.1.1.76

Abstract PDF: We clinically analysed 125 fractures of femoral neck which had been operated at the Department of Orthopedic Surgery, Yonsei University College of Medicine from January 1976 to December 1985. Of there, 45 fractures were treated with internal fixation, 43 fractures with primary hemiathroplasty, 37 freactures with total hip replacement arthroplasty. The criteria for internal fixation was fracture that could be reduced satisfactorilly and the age of the patients were under 65 years. The criteria for primary hemiarthroplasty was in elderly patient over 65 years, displaced, comminuted subcapital of trascervical fractures, irreducible fractures, pathological fractures and patients having generalised disease or senile psychosis. The criteria for total hip replacement arthroplasty was neglected fractured paients with significant medical problems and patients who had previous hip disease such as degenerative arghritis or rheumatoid arthritis. Following results were obtained. 1. Subcapital type(75%) according to anatomical classification and Graden type III,IV(80%) according to displacement were the most common type, respectively. 2. In cases of internal fixation, accurate medial cortical contact was required and redis-placement and collapse of fragments were prevented by supplementary fixation. 3. The overall rate of osteoporosis was reported to be 85%(below Singh index IV) in our series. The study should be directed not only on the fracture treatment but also on the prevention of refracture via the study of osteoporosis. 4. Good functional end results were obtained in 77% of the internal fixation group and primary hemiarthroplasy group. Internal fixation may be advantageous for femur neck fracture of elderly than arthroplasty in view of biomechanical status of hip joint.
