Abstract PDF: PURPOSE
To evaluate the effectiveness of a blocking screw in intramedullary nailing at the tibia proximal shaft fracture.
MATERIALS AND METHODS
63 tibia proximal shaft fractures from January 2000 to December 2002 treated with only intramedullary nailing were referred to as group I, and 8 fractures from January 2003 to December 2003 treated with both intramedullary nailing and the blocking screw were referred to as group II. Retrospective studies were done for group I and II. The incidence of nonunion and the postoperative angular alignments were compared. Malalignment was defined as an angle of 5 degrees anteroposteriorly or mediolaterally.
RESULTS
There were 7 nonunion (11%) in group I in compare with none in group II. There were 21 angular malalignments (33%) in group I and 1 in group II (12%) and most of them had valgus deformity or anterior anglulation. No complications were directly due to the use of the Blocking screw.
CONCLUSION
The technique of the blocking screw used to be one of the option for proximal tibial nailing at tibial proximal shaft fracture helps to overcome angular malalignments of bones.

Correlation Analysis of BMD in Proximal Femur and Spine: Jun Young Yang, Young Mo Kim; J Korean Soc Fract 2003;16(4):570-576. Published online October 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.4.570

PURPOSE
To analogize the result of the test through explaining the correlation of bone mineral density (BMD) test value between proximal femur and lumbar spine.
MATERIALS AND METHODS
It is based on 59 cases who visited the out-patient department. They were classified into two groups by age, group I (55~59 yr) and II (60~64 yr). Then we evaluated the average and the degree of correlation between the two groups and analyzed the correlation of the two sites according to the T & Z-score through the regression analysis.
RESULTS
In T-score, the correlation between L (independent variable, lumbar) and H (dependent variable, femur) indicated that L = 0.751 xH -0.195 for group I and L = 0.912 xH+0.31 for group II. In Z-score, the correlation was L = 0.647 xH -0.656 for group I and L = 0.897 xH -0.481 for group II.
CONCLUSION
It is regarded that there will be a clinical availability which can analogize the result of a part by using the result of the other part.

Abstract PDF

INTRODUCTION: Minimally invasive percutaneous plate osteosynthesis(MIPPO) was performed to treat distal tibial shaft fracture, and the results were compared to those of open plate fixation to find appropriate treatments MATERIALS AND METHODS: Among the patients who visited the Orthopedics Department at our hospital and were diagnosed with distal tibial shaft fracture, 12 cases that received MIPPO and 14 cases receiving open plate fixation were chosen for the study. The average age of patients were 57.8 and 50.8 years, and the male:female ratio was 1:1 in both cases. The average post-operative follow up period was 18 months and 19.5 months, and simple X-ray was done to evaluate the fracture healing.
RESULTS
The cases that received MIPPO, the operation time was 46.5 minutes and the average period of hospitalization was 25.3 days. There were no Nonunion, one case of delayed union, and one case of superficial infection. In the open plate fixation group, was 115.6 minutes and 48.3 days. Nonunion was in two cases, delayed union in two cases, superficial infection in one case, and deep infection in two cases. The nonunion cases were later given autogenous bone graft and fracture healing was attained.
CONCLUSION
By performing MIPPO quicker recovery of the patient can be made. Infection and nonunion, the most important complications due to operation, can be reduced. MIPPO thus seems to be the method leading to more close physiologic bone fusion in the treatment of distal tibial shaft fracture.

Abstract PDF: PURPOSE
To study the effectiveness of the ultrasound and LASER on the fracturehealing in rabbits.
MATERIALS AND METHODS
This study was performed on rabbits using the Hi-Tech 2000 (Ultrasound+LASER) which was made in our institute. After anesthesia of the rabbit, the shaft of tibia was fractured with Gigli saw under aseptic condition, and then intramedullary nailing using K-wire was performed. We evaluated left tibia as control and right tibia as experimental. we applicated ultrasound and LASER from 7 days after operation and sacrificed at 3 weeks and 5 weeks after operation. Gross findings, simple radiologic findings, and histologic findings were evaluated by modified Zorlu scoring system. With use of T-test of SAS system ( level of significance, P < 0.05 ), difference between left and right tibia were evaluated to be determined the effect of ultrasound and LASER on the fracture-healing.
RESULTS
At postoperative 3 weeks, differences were noted in 4 cases but we could detect no significant difference between left and right side. At postoperative 5 weeks, differences were noted 6 cases and significant difference was noted.
CONCLUSIONS
Seeing this results, ultrasound and LASER treatment was effective in fracture healing. However we think that additional studies for accurate quantitative and qualitative analysis, biomechanical test in callus, microangiographic study and clinical research to determine the effectiveness of ultrasound and LASER in clinical field are needed.

Popliteal Artery Injury Associated with Fracture and/or Dislocation of the Knee: Jun Young Yang, Kwang Jin Rhee, June Kyu Lee, Deuk Soo Hwang, Ki Yong Byun, Taek Soo Jeon; J Korean Soc Fract 2000;13(3):494-500. Published online July 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.3.494

Abstract PDF: PURPOSE
To compare the outcome in patients who have popliteal artery injury associated with fracture and/or dislocation around the knee according to treatment option.
MATERIALS AND METHODS
We have reviewed fourteen cases of popliteal artery injury patients associated with fracture and/or dislocation injury around the knee who had visited at Chungnam National University Hospital from April 1997 to July 1999.
RESULTS
Combined skeletal injuries included fracture of distal femur, fracture of proximal tibia, and dislocation of the knee. Internal or external fixation was applied for skeletal injuries. We repaired the injured popliteal artery using end-to-end anastomosis (3 cases), interposed saphenous vein graft (9 cases), prosthetic vein graft (1 case), or thrombectomy alone (1 case). The amputation rate was 21 % (3 out of 14 patients). In limb salvage cases, we evaluated the function of knee joint, and the results were as follows : good 5 cases, fair 3 cases, and poor 3 cases.
CONCLUSION
Early diagnosis and prompt management for injuries of the popliteal artery is the most important factor to save the limb. Also, complete resection of all injured portion of vessel and reconstruction of patency through interposed saphenous vein graft are most useful method.

Abstract PDF

We reviewed 14 patients treated with scaphocapitate fusion for Kienb.. ock's disease(Lichtman stage III) with mean follow-up of 26 months (ranging from 1 years to 5 year). There were five mens and nine womens. The mean age of patients at the time of operation was 46.1 years (ranging from thirty one to sixty). According to Lichtman's classification, All patients were stage III. Clinical assessments were evaluated using by pain relief, limitation in range of motion and clinical improvement. Radiologic assessment was evaluated by carpal height ratio. The mean range of motion is flexion 30 degree, extension 41 degree preoperatively, and flexion 29 degree, extension 41 degree postoperatively. The mean carpal height ratio is 0.49 preoperatively and 0.48 postoperatively. All of cases are relief of pain. Therefore radiographic and clinical satisfactory results were obtained. In conclusion, scaphocapitate fusion appear to be a very effective method for Lichtman stage III of symptomatic Kienb.. ock's disease.

The Treatment of the displaced Distal Radius fractures-Prospective study-: Jun Young Yang, Hyun Dae Shin, Kwang Jin Rhee, Jun Kyu Lee, Deuk Soo Hwang, Jang Ik Lee, Jung Hee Choi; J Korean Soc Fract 1999;12(2):411-421. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.411

Abstract PDF: Fractures of the distal end of the radius, including Colles'fractures, represent the most common fractures of the upper extremity. Over the past years, many clinicians had thought of fractures of the distal radius as being a group of injuries with a relatively good prognosis. Today, fractures of the distal radius are recognized as very complex injuries with variable prognosis that depend upon the fracture type and the treatment given. We performed a prospective study in 51 patients(52 cases), by using treatment protocol of Palmer, we treated each fracture according to physiological age, activity, X-ray findings and stability after closed reduction. Final outcomes were evaluated by modified clinical scoring system, criteria for anatomical results and combined functional and anatomical results. Results by using modified clinical scoring system were excellent; 8 cases, good; 16 cases, fair; 22 cases, and poor; 6 cases. Results by using criteria for anatomical results were excellent; 8 cases, good; 26 cases, fair; 10 cases; and poor; 8 cases. In wrist rating scales of New York Orthopaedic Hospital, excellent; 7 cases, good; 32 cases, fair; 6cases, and poor; 7 cases. In our study, fractures of the distal radius were occurred frequently in active young male with high energy injuries. Criteria about acceptable range of reduction in treatment protocol of Palmer were too wide to obtain satisfactory results. Results from many assessment systems did not matched with each other because of differences of point of views. The results of this study proposed that even acceptable reduction is obtained, better outcomes will be brought by operative modality due to decreased frequency of reduction loss and radial shortening. And also, physical therapy after fracture treatment is considered as one of the important factors influencing functional results and the satisfaction of patients themselves.

The Operative Treatment of Acetabular Fracture: Deuk Soo Hwang, Kwang Jin Rhee, Jun Young Yang, Jang Ik Lee; J Korean Soc Fract 1999;12(2):212-219. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.212

Abstract PDF: PURPOSE
To analysis clinical and radiological result of surgically treated acetabular fractures and to present appropriate surgical approach for fracture type. MATERIAL AND METHODS: A review of 51 surgically treated acetabular fractures, treated between April 1988 and October 1996, using single surgical exposures and combined surgical exposures was conducted. The classification was used Judet & Letournel,s classification and the surgical approach was applied Kocher-Langenbeck, Ilioinguinal, and Combined approach according to fracture aspect. The result was rated on a radiographic as well as a clinical result scale based on Matta,s.
RESULTS
The most common fracture was 14 posterior wall fracture and 7 transverse fracture. the surgical approach was applied Kocher-Langenbeck 29 cases, ilioinguinal 10 cases, and combined approach 8 cases, triradiate approach 2 cases and Extended iliofemoral approach 1 case. A satisfactory reduction was obtained in 87% of the cases (concentric, gap < 3mm). Clinical results were excellent in 28%, good in 54%, fair in 12%, and poor in 6%. Radiologic results at followup indicated 40% excellent results, 35% good results, 16% fair results, and 9% poor results. Postoperative complications appeared in 7 cases including posttraumatic arthritis 2 cases. Two patients later required total hip arthroplasty for avascular necrosis of femoral head and posttraumatic arthritis.
CONCLUSION
Ilioinguinal approach was good method for access to the anterior wall and column fracture, but in case of severe comminuted medial wall fracture company with anterior column, internal fixation is impossible. So, accurate assesment of the fracture pattern by careful radiologic analysis is essential. The posterosuperior dome fracture is important to anatomical reduction because of high risk of posttraumatic arthritis. In case of Transverse fracture, T-shape fracture, and both column, the more displaced column was reduced first, followed by opposite column after reduction identify by intraoperative radiography. We can be attained satisfactory reduction. Therefore, combined approach was good surgical method for this complex fracture.

Comparison of the Clinical Results Between the Plate Fixation and Intramedullary Nailing for the Diaphyseal Both Forearm Bone Fractures: Hyun Dai Shin, Kwang Jin Rhee, Jun Young Yang, Sung Ho Yun, Mun Jong Lee; J Korean Soc Fract 1999;12(1):135-144. Published online January 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.1.135

Abstract PDF

The fractures of the forearm bone are common and the forearm has the specific movement of supination and pronation. So, the goal of the treatment of forearm fractures is the recovery of rotatory function of the forearm as well as the function of the elbow and wrist. Surgical treatment usually is not necessory in children under 10 years of age because of remodelling potential and spontaneous correction ability. But, anatomical reduction and rigid fixation is essential in fractures of adult forearm above 15 years of age because of rotational deformity and angulation after forearm fractures may result in serious functional problems of the forearm. The purpose of the our retrospective study is to compare the clinical result between the plate fixation and intramedullary nailing of the diaphyseal both forearm bone fractures in adult. We reviewed 64 patients above 15 ages who had diaphyseal both forearm bone fractures, and were treated with fixation using compression plate or Rush pin. Forty patients were treated with both plates, 7 patients with both Rush pins, and 17 patients with plate and rush pin. Galeazzi or Monteggia fractures were excluded in this study. On final follow up, we performed the radiological analysis and compared the operation interval, immobilization period after operation, bone union time, functional result and complications in these groups. Functional results was more higher in both plate fixation, and complications were high in both intramedullary nailing. In conclusion, both plate fixation is the best treatment method in the diaphyseal both forearm bone fractures in adult. Thus in both forearm bone fractures, both plate fixation is recommended, but if it is not available, at least one bone with plate fixation is necessary

Analysis of Rick Fractors of HiP fractures after the eighth Decade of Life: Seung Ho Yune, Sang Rho Ahn, Chan Hee Park, Jun Young Yang; J Korean Soc Fract 1994;7(1):131-136. Published online May 31, 1994; DOI: https://doi.org/10.12671/jksf.1994.7.1.131

Abstract PDF: In Order to evaluate to the risk factors of hip fracture, we reviewed 34 patients, who were over 70 years old, from Jan. 1991 to Dec. 1993. The patients who have preexisting desease such as chronic illness, or in case of traffic accident, and fall down injury were excluded. We measured the singhs index and femoral neck-shaft angle on simple X-ray, bone mineral density for quantitative measurement of mineral on dual photon absorptiometry, and calcium, phosphate, and alkaline phosphatase on serologic study. We compared the results with control group who have not orthopaedic problems in 20 old aged person, and the results obtained were as follows. 1. The male to female ratio is 11:23, a high rate in female, and the mean age of patients is 74.3 years old, ragne from 70 to 89 years. 2. Femoral neck-shaft angle of patient group is 141.67Â±5.3 compared to 143.40Â±4.8 of control, showed statistical significance. 3. Bony trabeculae index of proximal femur of patient group is 1.83Â±0.83 compared to 2.91 Â± 0.86 of control, showed statistical significance. 4. In patient group, about 30% decreased in bone mineral density compared control. This result must be requisite to reinvestigation and statlstical analysis were not carried due to numbers of members of control. 5. There is no significant difference between two groups regard to serologic study. In summary, risk factors of hip fractures are aged female with decreased femoral neck-shaft angle, below third degree in singhs index and lower bone mineral density compared with same age. According to the our data, in case of hip fractures in old aged, for prevent the postoperative complication and refracture, prophylactic theraphy to collectible causes are required, in addllion to operative internal fixation.
