Hamstring injuries are common forms of muscle strains in athletes but a complete rupture of a proximal hamstring origin is rare. Often there is a considerable delay in diagnosis and stringent treatment because of its rarity, difficulty in clinical diagnosis, and initial attempts of conservative care. We report two cases of acute complete rupture of the proximal hamstring tendons treated with early surgical repair. The diagnosis and treatment of this unusual injury are discussed.

To identify the relation between simple reaction time and height and arm length, simple reaction time was performed to medical students with measurement of height, and arm length. Participants should answer questions about Smoking, drinking, sleep deprivation, history of diseaseand drug, whether to use computer or hot Mean height of men(n=98) was 173.0+/-4.79 cm, that of women (n-22) 161.7+/-4.33 cm. Mean arm length of men was 73.5+/-3.09 cm, and that of women 68.0+/-2.93 cm respectively. Height and arm length were statistically significantly different between-men and women (plt;0.01). Mean simple reaction time of men was 265.4+/-25.03 msec, that of women 286.8+/-28.48 msec. Mean simple reaction time was also statistically significantly different(p<0.01). As a result of correlation analysis, for men. None was significant. However, for women, height and arm length showed statistically significant, correlation with mean reaction time. Correlation coefficient of height and arm length were 0.45 (p<0.05) and 10.57 (p<0.05) respectively.

Hip subluxation and dislocation are common orthopaedic problems in children with cerebral palsy. Selective posterior rhizotomy(SPR) is a neurologic procedure aimed in reducing spasticity. Several recent studies have indicated a decrease in spasticity and functional improvement after SPR, and also decrease the tendency toward hip subluxation in children with cerebral palsy. This is a retrospective study to examine whether SPR halts hip subluxation. Between May 1994 and July 1996, 22 children below age of 5 underwent SPR. Twenty children were spastic diplegic types and 2 were mixed type and quadriplegic type respectively. Approximately 50-80% of L2-Sl level dorsal roots was cut, and 13 children had 50% of both Ll roots cut. Migration percentage score (MP) was used to determine progression of hip subluxation during the follow up period (12 36 mos.; Average 15 mos.). Of the total 44 hips in 22 patients, 45.5% (20 hips) improved, 34% (15 hips) remained unchanged, and 20.5% (9 hips) were worsened after SPR. Radiographic stability was achieved in 79.5%. Ll root cut rate (Ll SPR) was 55.5% for improved hips, 67% for unchanged hips, and 50% for worsened hips. Two patients had undergone orthopaedic procedure for progressive hip migration. Most patients experienced postoperative hip stability after SPR, but 20.5% were worsened and 2 patients had orthopaedic procedure. Also it is unlikely that Ll root involvement prevents progression of hip migration.

Following the implementation of a long-term care insurance system for the elderly in Korea, many nursing homes have been established and many more patients than ever before have been living at nursing homes. Despite the fact that this is a high-risk group vulnerable to hip fractures, no study has yet been conducted in Korea on hip fracture incidence rates and prognoses among patients residing at nursing homes. We recently studied 46 cases of hip fracture in nursing homes; more specifically, we investigated the most common conditions under which fractures occur, and examined the degree of recovery of ambulatory ability and the mortality within 1 yr. Among those who had survived after 1 yr, the number of non-functional ambulators increased from 8 hips before hip fracture to 19 hips at final post-fracture follow-up. These individuals showed poor recovery of ambulatory ability, and the number who died within one year was 11 (23.9%), a rate not significantly different from that among community-dwelling individuals. It was evident that hip-joint-fracture nursing home residents survived for similar periods of time as did those dwelling in the community, though under much more uncomfortable conditions. The main highlight of this report is that it is the first from Korea on nursing home residents' ambulatory recovery and one-year mortality after hip fracture. The authors believe that, beginning with the present study, the government should collect and evaluate the number of hips fractured at nursing facilities in order to formulate criteria that will help to enable all patients to select safer and better-quality nursing facilities for themselves or their family members.

PURPOSE: To evaluate the effectiveness of percutaneous transluminal angioplasty(PTA) and to determine thefactors affecting the long-term patency rate in the management of insufficient hemodialytic arteriovenousfistula(AVF). MATERIALS AND METHODS: Forty-nine cases of insufficient hemodialytic AVF were treated in 44patients(native AVF:20, graft AVF:29, M:17, F:27, Age:22-70 years). In 28 thrombus patients, thrombolysis wasperformed with urokinase, and was followed by PTA. The initial success rate and complications of PTA wereevaluated. According to the site and length of the stenosis, type and age of the AVF, the presence or abscence of thrombus, a history of diabetic mellitus, the patient 's age, and the duration of renal failure, patency rateswere compared within each subgroup using the Kaplan-Meier logrank test. RESULTS: The initial success rate of PTAfor insufficient hemodialytic AVF was 88%(43/49), the patency rate of PTA was 67% at 6 months, and 50% at 12months. The initial success rate of thrombolysis was 89%(25/28). The complication rate of PTA was 12%(6/49), ofwhich five cases were vein rupture, and one was subcutaneous hematoma. Statistically, the patency rates in theabove mentioned subgroups were not significantly different. CONCLUSION: PTA with or without thrombolysis offerssafe and effective management of insufficient hemodialytic AVF.

BACKGROUND: Mild iron deficiency anemia is known to be asymptomatic in most of the cases. In view of this, we studied response of the mild anemics to the maximal exercise loading test to learn whether or not they respond similarly to the normals. METHODS: The maximal exercise loading tests by Bruce's protocol were carried out in 22 female asymptomatic anemics with hemoglobin level of between 10.0gm/dL and less than 12.0gm/dL, and the results were compared with those of 44 non-anemic matched controls with mean hemoglobin level of 13.1gm/dL. The ages in both groups were in their 30's to 40's, and even the anemics were otherwise normal clinically and on various laboratory tests. RESULTS: There were no significant difference between two groups in VO2 max, HR max, VCO2 max and VE max and their derivatives including VT/VC and VE/MVV. CONCLUSIONS: Our results indicate that in patients with mild iron deficiency anemia, the cardiorespiratory response to maximal exercise loading is not different from the normals, and suggest that oxygen transport to tissues is not affected even at maximal exercise. probably by adaptive compensatory mechanism.

OBJECTIVE: To investigate the relationship between cognitive perceptual abilities of elderly drivers based on the Cognitive Perceptual Assessment for Driving (CPAD) test and their accident and penalty histories. METHODS: A total of 168 elderly drivers (aged ≥65 years) participated in the study. Participant data included CPAD scores and incidents of traffic accidents and penalties, attained from the Korea Road Traffic Authority and Korea National Police Agency, respectively. RESULTS: Drivers' mean age was 70.25±4.1 years and the mean CPAD score was 52.75±4.72. Elderly drivers' age was negatively related to the CPAD score (p<0.001). The accident history group had marginally lower CPAD scores, as compared to the non-accident group (p=0.051). However, incidence rates for traffic fines did not differ significantly between the two groups. Additionally, the group that passed the CPAD test had experienced fewer traffic accidents (3.6%), as compared to the group that failed (10.6%). The older age group (12.0%) had also experienced more traffic accidents, as compared to the younger group (2.4%). CONCLUSION: Overall, elderly drivers who experienced driving accidents had lower CPAD scores than those who did not, without statistical significance. Thus, driving-related cognitive abilities of elderly drivers with insufficient cognitive ability need to be further evaluated to prevent traffic accidents.
