PURPOSE: To study prognostic factors of unilateral calcaneus fracture underwent surgery. MATERIALS AND METHODS: We selected appropriate 60 cases of 236 calcaneus fracture cases between March 1985 and March 2004, and analyzed the correlation between sex, age, smoking, injury mechanism, Essex-Lopresti classification of calcaneus fracture, preoperative Bohler angle, postoperative Bohler angle, postoperative 1 year Bohler angle and Visual Analogue Scale (VAS), P.S. Kerr's Calcaneal Fracture Score (CFSS). The average age was 41.4 and average follow up period was 74 (12 to 240) months. RESULTS: For follow up period, average VAS is 3.43 and CFSS is 81.23. The sex, age, smoking, injury mechanism, and preoperative, postoperative, postoperative 1 year Bohler angle had no correlation with the prognosis. But the Essex-Lopresti classification of calcaneus fracture, tongue type had better prognosis than joint depression type (VAS : p=0.041, CFSS : p=0.021). CONCLUSION: In unilateral calcaneus fracture, the sex, age, smoking, injury mechanism, preoperative Bohler angle, postoperative Bohler angle, postoperative 1 year Bohler angle had no correlation with the prognosis of fracture, but in Essex-Lopresti classification, the tongue type fracture had better prognosis than the joint depression type.

This experimental studies was to investigate the location of PNS and CNS labeled neurons following injection of 2% WGA-HRP and pseudorabies virus (PRV), beta-galactosidase inserted Bartha strain, into the epididymis of rats. After survival times 4~5 days following injection of 2% WGA-HRP and PRV-Ba-Gal, the rats were perfused, and their brain, spinal cord, sympathetic ganglia and spinal ganglia were frozen sectioned (30 mm). These sections were stained by HRP histochemical and beta-galactosidase histochemical staining methods, and observed with light microscope. The results were as follows : 1. The WGA-HRP labeled sympathetic ganglia projecting to the epididymis were observed in pelvic ganglion and L1-6 lumbar sympathetic ganglia. 2. The WGA-HRP labeled spinal ganglia projecting to the epididymis were observed in L1-6 spinal ganglia. 3. The beta-galactosidase labeled neurons projecting to the epididymis were observed in lamina VII of cervical segments. In thoracic segments, beta-galactosidase labeled neurons were observed in dorsomedial part of lamina I, II and III. Dense labeled neurons were observed in intermediolateral n. and dorsal commissural n.. In lumbar segment, labeled neurons were observed in lamina III, IV, V, dorsal commisural n. and superficial dorsal horn. 4. In the medulla oblongata, beta-galactosidase labeled neurons projecting to the epididymis were observed in the trigeminal spinal n., A1 noradrenalin cells/C1 adrenalin cells/caudoventrolateral reticular n., rostroventrolateral reticular n., area postrema, n. tractus solitarius, raphe obscurus n., raphe pallidus n., raphe magnus n., parapyra-midal n., lateral reticular n. and lateral paragigantocellular reticular n.. 5. In the pons, labeled neurons were observed in Kolliker-Fuse n., locus coeruleus, subcoeruleus n. and A5 noradrenalin cells. 6. In midbrain, labeled neurons were observed in periaqueductal gray substance, retrorubral n., substantia nigra and dorsal raphe n.. 7. In the diencephalon, labeled neurons were observed in paraventricular hypothalamic n., lateral hypothalamic nucleus., medial preoptic n. and retrochiasmatic n.. These results suggest that WGA-HRP labeled neurons of the spinal cord projecting to the rat epididymis might be the first-order neurons related to the viscero-somatic sensory and sympathetic postganglionic neurons, and beta-galactosidase labeled neurons of the brain and spinal cord may be the second and third-order neurons response to the movement of vascular smooth muscle in epididymis. These beta-galactosidase labeled neurons may be central autonomic center related to the integration and modulation of reflex control linked to the sensory and motor system monitoring the internal environment. These observations provide evidence for previously unknown projections from epididymis to spinal cord and brain which may be play an important neuroanatomical basic evidence in the regulation of epididymal function.

Displaced fractures of the upper sacrum are a rare type of high energy injury, such as a fall, with similar neurological symptoms and fracture patterns. The authors treated 4 patients with these fracture patterns surgically or conservatively and followed them up for at least 1 year. We report these 4 cases with a review of the relevant literature.

This paper reports a rare case of a lumbosacral dislocation associated with symphysis pubis separation and cauda equina syndrome. A 39-year-old male who diagnosed traumatic lumbosacral dislocation underwent an open reduction without fusion. After an open reduction and internal fixation of a symphysis pubis separation, a missed lumbosacral dislocation was diagnosed and an open reduction was performed without fusion. Due to the symphysis pubis separation, the patient was not allowed weight bearing for 3 months, which then began from wheel chair ambulation. At the 6-month follow up evaluation, there was no back pain but the patient reported mild S1 nerve root sensory symptoms. Lumbosacral dislocation is common in high energy polytrauma patients and can be misdiagnosed. However, prompt reduction without fusion is a good alternative treatment.

BACKGROUND: To determine the prevalence of spondylolysis in a selected population and evaluate the association of spondylolysis with low back pain (LBP). Spondylolysis is widespread in the general population but the prevalence of spondylolysis and its relationship with LBP in the Korean population is controversial. METHODS: A sample of 855 participants (age, 20 to 86 years) from our medical center who underwent multidetector computed tomography (CT) imaging to assess abdominal and urological lesions were enrolled in this study. The occurrence of LBP requiring medication in the preceding 12 months was evaluated using a self-report questionnaire (a modified Nordic Low Back Pain Questionnaire). The presence of spondylolysis was characterized by CT imaging. Multiple logistic regression models were used to examine the association between spondylolysis and LBP, while adjusting for gender and age. RESULTS: Seventy-eight study subjects (9%) demonstrated spondylolysis on CT imaging. There was no significant difference between the age groups (p = 0.177). The p-value of gender was 0.033 but this was not significant due to the selected population bias. Three hundred eleven study subjects (36%) had back pain. There was a significant difference between gender (p = 0.001). No significant association was identified between spondylolysis and the occurrence of LBP. CONCLUSIONS: The prevalence of LBP was 36.37% and the prevalence of lumbar spondylolysis in a selected population, who visited hospital for abdominal or urological lesions except LBP, was 9.12% based on CT imaging. Males demonstrated a similar presence of LBP to females but a significantly higher incidence of spondylolysis (p = 0.033). The prevalence of spondylolysis was not associated with the presence of LBP and age in adulthood.

Fracture-dislocation of the sacrum that has not yet fully developed is common in the distal sacrococcygeal joint of children, but this injury is rarely seen in 1st Sacrum. Most of these patients have a severe neurological deficit, so this injury generally requires surgical decompression. We managed a three year old patient who had a S1 fracture-dislocation without a neurological deficit, and the patient was treated with simple skin traction and bed rest without surgery. The child had a satisfactory result, so we report on this case with reviewing the relevant literatures.

PURPOSE: The Garden classification by which femur neck fracture is classified and the Boyd-Griffin classification by which trochanteric fracture is classified are studied on the reproducibility, repeatability, interobserver's and intraobserver's reliability and then reliability. MATERIALS AND METHODS: 56 cases in femoral neck fracture and 60 cases in trochanteric fracture who were operated from May 1999 to December 2003 were classified by three observers who are hip surgeon, orthopaedic surgeon and senior residentship doctors three times. Femur neck fracture was classified by Garden's method which used commonly and trochanteric fracture was classified by Boyd-Griffin method which is classified by the pattern of fracture and degree of comminution. We got the interobserver's and intraobserver's Kappa score using the Stata 7.0 statistically. The statistical analysis was made by Stata 7.0. RESULTS: Garden classification in femur neck fracture showed moderate agreement in intraobserver reliability and fair agreement in interobserver reliability. Boyd-Griffin classification in trochanteric fracture showed substantial agreement in intraobserver reliability and moderate agreement in interobserver reliability. CONCLUSION: Boyd-Griffin classification showed over moderate agreement but Garden classification showed fair agreement, so using Garden classification in femur neck fracture has some problem in reliability and application.

BACKGROUND: To characterize the recently issued femur shaft insufficiency fracture in terms of a patient's own epidemiological status. METHODS: Fourteen patients were treated for insufficiency fracture from July 2002 to June 2008, excluding cases including the risk factors of insufficiency fracture. All patients were female, and their mean age was 75.6 years (range, 65 to 89 years). The mean follow-up period was 50.6 months (range, 14 to 86 months). RESULTS: The mean body weight of the Koreans in the same age group was 58.1 +/- 9.7 kg, and the mean height was 155.5 +/- 8.8 cm. The mean body weight of our insufficiency fracture patients was 45.7 kg and it was statistically significantly lower than that of the Koreans in the same age group (p < 0.001). The mean height was 147.3 cm and it was significantly shorter than the mean height of the Koreans in the same age group (p = 0.002). In regard to menopausal time, the mean menopausal time of the Koreans was 48.0 +/- 4.2 years, it was 44 years in our study, as menopause occurred statistically significantly earlier (p = 0.017). The patients with insufficiency fracture showed statistically lower weight, shorter stature and an earlier menopausal period than that of the general population. CONCLUSIONS: In early menopausal, underweight, and short patients prescribed osteoporosis medication for an extended period of time, if predromal symptom is present, it is necessary to suspect insufficiency fracture of the femur.
