Purpose: This study aimed to evaluate the outcomes, including the complications, of open reduction and internal fixation using a headless cannulated compression screw for a fifth metatarsal base fracture. Materials and Methods: We retrospectively investigated 11 patients with 5th metatarsal base fracture who were treated with a headless cannulated compression screw. The mean follow-up period was 13 months (8~15 months), and the mean age was 46.5 years (21~70 years). We analyzed the patients' sex, age, time to union, amount of fracture displacement, and complications. The American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score was used for clinical assessment. Results: The average amount of displacement decreased significantly from 3.4 mm (2.1~5.2 mm), preoperatively, to 0.4 mm (0~1.3 mm), postoperatively (p<0.001). The average bone union time was 54.1 days (41~68 days). There were no complications, such as a metal failure, irritation, and loss of a reduction. The mean AOFAS midfoot score was 97.7 (90~100) at 6 months, postoperatively. Conclusion: We suggest that a headless cannulated compression screw for 5th metatarsal base fracture is a useful and alternative method for a firm fixation without complications.

Objective : Percutaneous vertebroplasty is an effective and minimally invasive procedure consisting of the injection of a PMMA(polymethyl methacrylate) into the vertebral body compression fracture with osteoporosis. Matherials and Methods : Twenty-eight procedures were performed for vertebral body compression fractures with osteoporosis in 25 patients(22 women, 3 men). The mean age was 65.9 years old. The inclusion criteria for percutaneous vertebroplasty were 1) acute vertebral body compression fracture with osteoporosis, 2) expected high operative morbidity in old age, 3) no neurologic deficits, 4) no or minimal canal enchroachment, 5) patient refusal of invasive surgery. All patients underwent MR images before the procedure. Under local anesthesia, after the percutaneous needle puncture of the involved vertebra via a transpedicular approach and venography using the water soluble contrast material, PMMA injection was introduced into the fractured vertebral body. Results : The procedure was technically successful in all patients. All patients experienced excellent pain relief (complete pain relief ; 10, marked pain relief ; 14). One patient experienced marked pain relief, however, the patient died during the follow-up period due to stomach cancer. There were twelve paravertebral tissue leaks, twelve paravertebral venous plexus leaks, four epidural leaks and one intradiskal leak, but no clinically significant complications occurred in all patients. Conclusion : Percutaneous vertebraoplasty is a valuable procedure in the treatment of vertebral body compression fracture with osteoporosis, providing immediate pain relief and early mobilization. MRI is the most reliable diagnostic tool for identifying painful fractured vertebral body.

In this study, the fracture strength for fracture mechanism porous calcium phosphate made from sintered with ${\beta}$-tricalcium phosphate obtained by wet precipitation procedure is analyzed using finite element method and experiment measurement. First, three $3{\times}3{\times}3mm^3$ and $5{\times}5{\times}5mm^3$ specimens are prepared and tomographic images of one $5{\times}5{\times}5mm^3$ specimen are obtained by micro focus X-ray CT. The compression tests using the specimens are carried out to measure the elastic modulus and fracture strength to analyze the fracture mechanism of porous calcium phosphate specimen. The tomographic images are reconstructed by 3D reconstruction program. The finite elements are directly built up in the reconstructed specimen. The numerical simulation for the compression tests is performed using the element. The mechanism of calcium phosphate of simulation are obtained by the compression tests using there cylindric specimen of height 19.5 mm and diameter 10 mm. From the results, the applicability of porous calcium phosphate is evaluated to care fracture and vacant bone of a patient as the reinforcement material.

Objective : The purpose of this study was to determine the optimal volume of injected cement and its distribution when used to treat vertebral compression fractures, and to identify factors related to subsequent vertebral fractures. Methods : A retrospective analysis of newly developing vertebral fractures after percutaneous vertebroplasty was done. The inclusion criteria were that the fracture was a single first onset fracture with exclusion of pathologic fractures. Forty-three patients were included in the study with a minimum follow up period of six months. Patients were dichotomized for the analysis by volume of cement, initial vertebral height loss, bone marrow density, and endplate-to-endplate cement augmentation. Results : None of the four study variables was found to be significantly associated with the occurrence of a subsequent vertebral compression fracture. In particular, and injected cement volume of more or less that 3.5 cc was not associated with occurrence (p = 0.2523). No relation was observed between initial vertebral height loss and bone marrow density (p = 0.1652, 0.2064). Furthermore, endplate-to-endplate cement augmentation was also not found to be significantly associated with a subsequent fracture (p = 0.2860) by Fisher's exact test. Conclusion : Neither volume of cement, initial vertebral height loss, bone marrow density, or endplate-to-endplate cement augmentation was found to be significantly related to the occurrence of a subsequent vertebral compression fracture. Our findings suggest that as much cement as possible without causing leakage should be used.

Purpose: To investigate the results of treatment of reverse oblique trochanteric fractures with compression hip screw. Methods: We reviewed the results of 12 cases of reverse oblique trochanteric fracture treated with compression hip screw from January 2000 to December 2006 which could be followed up for more than 1 year. The mean follow up period was 26 months (15~40). The mean age was 48 years old. Injury mechanism was composed of 6 cases of traffic accident and 6 cases of fall down. 8 persons were man. We investigated the union time, degree of neck-shaft angle change, amount of sliding of compression hip screw, complications, functional and clinical results. Results: 10 cases were united and the mean union time were 5 months (3~8). The mean neck-shaft angle change was 3.5 degrees (0~12). The amount of sliding of compression hip screw was 8.9 mm (2~24). There were six coxa vara, six leg due to coxa vara shortening, two nonunion, and one superficial infection. Unsatisfactory results of Jensen's social function score and Parker and Palmer's mobility score were studied. Conclusion: The results of treatment of reverse oblique trochanteric fractures with compression hip screw were relatively unsatisfied.

In this study, theoretical stress field analysis near the crack tip under tension-compression loading was performed. The results of the theoretical stress analysis were compared to the results of Finite Element Method(FEM). From this study, generation of tensile residual stress at crack tip was proved after 1-cycle of tension-compression loading, and the fracture toughness and the fracture load of a structure can be decreased by the residual stress.

Methods : We investigated 28 cases of patients with thoracolumbar compression fracture. We divided patients into two groups : We treated one group with complex oriental medical treatment focusing on Bee Venom Acupuncture therapy, and did the other group with complex oriental medical treatment focusing on acupuncture therapy. To investigate the effectiveness of treatment applied for two groups, we used Visual Analog Scale(VAS) and Oswestry Low-back Pain Disability Index(ODI). We compared the VAS score and ODI score of two groups statistically. Results : 1. Female is prominent in distribution of sex, the average age bracket is 70's, and the largest group was Faccidental fall in the distribution of cause. 2. In regard to level of injury, T12 was found to be most prominent, followed in turn by L1, L2. In regard to grade of clinical symptoms, Grade III was most prominent, followed by Grade IV, Grade II. 3. As a result of evaluation by using VAS score and ODI score, treatment score at final was significantly different from that at the baseline in each group. 4. After treatment, Bee Venom acupuncture therapy group showed significant difference on VAS score and ODI score compared with acupuncture therapy group. Conclusions : Bee Venom acupuncture therapy can be available for relieving symptoms related with thoracolumbar compression fracture.
