Femoroacetabular Impingement Syndrome / 대한정형외과학회잡지

Femoroacetabular impingement (FAI) results from abnormal anatomic relationship between acetabulum and femoral head-neck junction, which causes secondary chondrolabral injury. FAI is the common cause of hip joint pain in young adults who have nearly normal hip joint structure. The pain usually progresses on hip flexion and internal rotation. Although it is still controversial whether FAI is one of the reason of secondary hip osteoarthritis or the contrary, instruments and surgical technique for treating FAI is continuing to improve. When we initially diagnosed with FAI, conservative treatment is recommended. But if the conservative treatment has no response, we can consider surgical intervention. The arthroscopic technique is one of the promising options, and it is the fastest growing fields for the treatment FAI.

Superficial Fibromatosis Mimicking Glomus Tumor of the Second Toe

Various types of tumor can occur in the subungual space, including glomus tumors, subungual exostosis, hemangioma, epidermal cysts, and malignant tumors. While fibromatosis can occur at various sites throughout the body, it is very rarely seen in the toe. Here, we are the first to report a case of superficial fibromatosis mimicking a glomus tumor in the subungual space of the second toe. The presentation of this condition shows the possibility of encountering uncommon superficial fibromatosis in the distal phalanx of the toe, and suggests that superficial fibromatosis should be included in the differential diagnosis of a glomus tumor in the toe.

Multiple Non-contiguous Spine Fractures with Concomitant Injuries: A Case Report

Multiple non-contiguous spinal fracture is a special type of multi-level spinal injury, which is rare but most frequently occur in motor vehicle accident or a falling from a height. We report five patients of multiple non-contiguous spinal fractures. All patients underwent segmental pedicle screws fixation without fusion for preserving facet joints and minimizing blood loss and operation time. We performed necessary operation for any concomitant injuries at the same day.

The Association between the Bone Mineral Density and Spinal Osteoarthritis in Osteoporotic Thoracolumbar Compression Fractures

OBJECTIVES: The purpose of this study was to determine the association between the bone mineral density (BMD) and severity of spinal osteoarthritis (spondylosis) in osteoporotic spinal compression fracture. METHODS: Fifty six patients were evaluated 66 cases had an osteoporotic thoracolumbar compression fracture between January 2008 and June 2010. The average patient age was 76.2 years (M/F : 8/48). Age and body mass index (BMI, kg/m2) were measured, and the BMD was performed using peripheral quantitative computed tomography (pQCT). Simple thoracolumbar (T-L) spine lateral radiography was evaluated for three criteria: presence of osteophytes, disc space narrowing and vertebral body sclerosis. The findings were graded 0 to 3 and analyzed statistically for a correlation with the BMD and fractured vertebrae. RESULTS: Acute compression fractures comprised of 15 cases and the most common site of acute fractures with old fractures was lumbar spine (L1; 30 cases, 45.4%). The average of BMI was 23.32 and BMD (T-score) was -4.47. Pearson's rho showed a positive association between the weight, height and the BMD (P < 0.01). In terms of the BMD versus spondylosis, there was a positive association with high score in the high order cortical bone. Compression fractures occurrence rate in the absent and present of spondylosis was 74.3% and 22.4%, and 69% occur in the spinal segmental with no bony spur with chi-square test (P < 0.01). CONCLUSION: In the present of spondylosis was high score of cortical BMD and low rate of compression fracture. Spondylosis could be one of a factor of the occurrence in acute and adjacent compression fracture after old fractures.

Relationships of Bone Mineral Density, Blood Pressure, and Physical Characteristics of Third and Fourth Decade College Students / 대한정형외과연구학회지

The purpose of this study was to analyze the relationship of body mass index (BMI), bone mineral density (BMD) and blood pressure (BP) in third and fourth decade college students. Total of 114 (67 male and 47 female) students who received health examination in April 2010 participated in this research. Bone status was measured by a peripheral dual energy X-ray absorptiometry method and T-score was calculated via WHO guideline. For body composition measurements, body fat, height and weight were measured and BMI was calculated. Among male students, 3.6% belong to the UW (under weight) group, 49.1% to the NW (normal weight) group, 18.2% to the OW (over weight) group and 29.1% belong to the obese group, while 2.1% of female students belong to the UW group, and 68.1% to the NW group, 14.9% to the OW group and 14.9% belong to the obese group. Differences of body weight among male and female students were statistically significant (p<0.001). Above overweight groups showed higher systolic and diastolic BP than normal group. Differences among two groups were statistically significant (systolic BP: p=0.041, diastolic BP: p=0.021). The mean BMI of normal BP group is 22.6+/-2.87, hypertension group is 24.1+/-2.95. Differences among two groups were statistically significant (p=0.045). The mean T-score of male students is -0.1+/-1.17, female is -0.6+/-0.88(total -0.5+/-0.91). Differences of T-score among male and female students were statistically significant (p=0.007). In conclusion, our results showed that many college students had the problems in the BMI, BMD and BP, and BP increased according to the increase of BMI. Therefore, nutritional education and weight control is required for normal blood pressure and bone health.
