Published online October 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.4.390

PURPOSE
To evaluate the advantages of reduction of lateral and posterior displacement in unstable intertrochanteric fractures of the elderly.
MATERIALS AND METHODS
From January, 1997 to December, 2001, we reviewed 23 cases of unstable intertrochanteric fractures in the elderly, which underwent by reduction of lateral and posterior displacement. Using the device of internal fixation is dynamic compression hip screw (DHS), the follow up period was minimally 12 months (mean 16 months). We estimated the clinical results, the radiologic results and complications.
RESULTS
The satisfactory results was regarded as walking with walking frame and 21 cases (91.3%) showed satisfactory results. The average period of radiologic union was 18 weeks. The average sliding of lag screw was 5.3 mm and the average changes of femoral neck-shaft angle was 2.6 degree. As for the complications, 2 cases showed superficial infection and 2 cases showed pain over trochanteric area.
CONCLUSION
In the unstable intertrochanteric fractures of the elderly, treatment with reduction of lateral and posterior displacement can be considered one of reduction technique.

Evaluation of Rotational Displacement of the Posterior Facet on the Sagittal Plane in Computed Tomographic Images of Calcaneal Fractures: Su Young Bae, Yi Kyoung Shin, Jong Oh Kim, Jung Hee Lee, Churl Woo Lee, Jae Hung Shin; J Korean Fract Soc 2005;18(2):165-169. Published online April 30, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.2.165

Abstract PDF

PURPOSE
To find out whether or not the computed tomographic (CT) classification systems of the calcaneal fracture are efficient in illuminating displaced posterior facet fragment and the degree of displacement can be evaluated by analyzing serial CT images.
MATERIALS AND METHODS
Seventy-seven hundred calcaneal fractures were classified by CT classification systems including Sanders classification, and the sagittal rotation angle of the posteior facet fragment was measured on the plain lateral radiograph. Among the serial axial CT images, a number of images with the cortical bone embedded in the cancellous portion were recorded and any significant relationship between each data were evaluated.
RESULTS
The conventional CT classification systems are rather insufficient in illuminating the extent of sagittal rotatory displacement. However, the number of CT images in which the cortical radiodensity was observed showed a significantly related with the degree of displacement.
CONCLUSION
The conventional CT classification of the calcaneal fractures is unsatisfactory in expressing the degree of sagittal rotatory displacement of the posterior facet fragment; this problem may be alleviated by observing the number of axial CT images in which cortical radiodensity was revealed within the calcaneal body.

The Cause of the Nonunion of the Mid-clavicle Fractures: Jung Ro Yoon, Jae Ik Shim, Taek Seon Kim, Sung Jong Lee, Young Bae Kim, Hack Jun Kim, Kuk Whan Ahn, Jae Young Chang, Myung Pyo Hong; J Korean Soc Fract 2002;15(4):538-544. Published online October 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.4.538

Abstract PDF: PURPOSE
Because the prognosis of the mid 1/3 clavicle fracture is good, the conservative treatment with a figure of 8 bandage is the gold standard and the nonunions are rare.However, recently surgical treatment is recommended when the shortening and displacement is severe because of the high nonunion rate and the poor clinical result. This study was undertaken to evaluate that the shortening and displacement at fracture site are associated with the development of nonunion.
MATERIALS AND METHODS
We analysed the 194 fractures of mid 1/3 clavicle in adults which had been treated conservatively from February 1993 to January 2002 and did the retrospective study. Of these, 78cases were originally in the middle third of the clavicle and had been completely displaced. We reviewed 63 of these cases. The shortening and displacement at the fracture site was measured on the initial roentgenogram. And the analysis of the patients 'chart was done for another predisposing nonunion factors. Nonunion and delayed union are considered to be present when there has been little or no progression of clinical or radiographic healing at a minimum of 4 months after injury.
RESULTS
15 of the 63cases had developed nonunion.. The average 8.6mm(2mm-17mm) shortening and average 9.7mm(2-22mm) in the union patients. The average 14.5mm(3mm-37mm) shortening and average 17.3mm(4-25mm) in the nonunion patients. We found that initial shortening > or =1 8 m m ( Fisher's exact test, p <0.01) and initial displacement > or =16mm(Chi-square test, p <0.01) at the fracture site were siinificantly associated with the development of nonunion.
CONCLUSION
The conservative treatment with figure-8-bandage is the gold standard in the clavicle middle one third fracture. However, the nonunion is commonly occurs in the cases of more of severely shortened and displaced fractures. If there are no signs of callus formation and the patient complains of pain after several weeks, osteosynthesis should be considered.

Radiologic assessment of the displacement of the greater tuberosity of the humerus: Jaedoo Yoo, Jangwoon Shon; J Korean Soc Fract 2001;14(2):223-227. Published online April 30, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.2.223

Abstract PDF: PURPOSE
The purpose of this study is to evaluate the correlation between the amount of displacement of the greater tuberosity of the humerus and the that of the radiographic displacement.
MATERIALS AND METHODS
Dry bones of the scapula, humerus were fixed to the board. After cutting the greater tuberosity, the center of the lesser tuberosity, the anterior and inferior margin of the greater tuberosity fragment, the anterior edge of the bone defect at the greater tuberosity were marked with wire. The humerus were placed in the neutral position, 60 degree internal rotation, 15 degree external rotation, 45 degree abduction, 90 degree abduction. The radiographs were taken in the position of the 5, 10, 15, 20, 25mm posterior superior displacement of the fragment respectively.
RESULTS
The correlation coefficient between the amount of displacement of the greater tuberosity of the humerus and the that of the radiographic displacement were followings; 0.599(p=0.285) in the neutral anterior posterior view, 0.790(p=0.112) in the 60 degree internal rotation view, 0.522(p=0.367) in the 15 degree external rotation view, 0.290(p=0.635) in the 45 degree abduction axillary view, 90 degree abduction axillary view.
CONCLUSION
The 90 abduction axillary view was the most appropriate radiograph to evaluate the amount of displacement of the greater tuberosity of the humerus.

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.

Treatment of Distal Tibial Epiphyseal fracture Salter-Harris Type I & II: Sung Ho Hahn, Bo Kyu Yang, Seung Rim Yi, Sung Hwan Yoo; J Korean Soc Fract 1999;12(4):1065-1070. Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.1065

Abstract PDF

It is known that the Salter-Harris type I and II fractures of the distal tibial epiphysis usually can be treated by conservative method. But according to Spiegel, unpredictable group(type II) fractures might have more complications than expected when treated by conservative method without accurate reduction. Eleven cases in type I or II fractures were treated at the National Police Hospital between March 1992 and March 1997. If more than 2mm displacement was present compared to contralateral side after closed reduction, open reduction and internal fixation method was done and in those all cases, periosteal interposition was found on the operative field that might interrupt anatomical reduction and cause late complications such as angular deformity.
