Bone tumor in the trochanteric area is not infrequent and it is important to differentiate the tumors in this area for diagnosis, early settings of therapeutic plans and prognostic previsions. Twenty-one cases of benign bone tumors in the trochanteric area treated at Dept. of Orthopedi Surgery, College of Medicine, Ewha Womans University Hospital, from January 1975 to December 1983 were analysed and following results were obtained. l. of 21 cases, 10 cases were fibrous dysplasia, 6 cases were simple bone cyst, 3 were giant ce tumor and 2 were aneurysmal bone cyst. 2. Pathologic fractures were accompanied in 6 cases; 3 of fibrous dysplasia, 2 of simple bone cy: and 1 of aneurysmal bone cyst. 3. After treatment with curettage, bone graft and instrumentation, 3 cases recurred; 2 cases of fibrous dysplasia and 1 of simple bone cyst. 4. As prognostic factors, completeness of curettage, amount and source of bone graft were considered to be important.

One of the biggest change in the history of the Journal of Korean Neurosurgical Society(JKNS) had been introduced in 2005. From January 2005, all manuscripts submitted to JKNS should be written in English. This new regulation was followed by many changes in characteristics of the papers published on JKNS in 2005. The authors present an analysis of papers published on JKNS and compared with those of 2004 and 2003. In total, 184 articles were published in 2005. Since a review article was requested by the editorial office to the authors, 183 articles were peer reviewed. Eighty five clinical articles, 75 case reports, 19 laboratory investigations, two special articles and two technical reports were printed. This distribution was not statistically different from 2004's distribution (p=0.67), even though the ratio of clinical articles was decreased to 46.4% from 54.4%. Due to the change in language specification, English articles were increased with statistical significance (p<0.001). There were several events related with copyright of the contents of the papers published on JKNS. We think these are some good points came with change in official language to English. General trends of the papers seemed to be in the right way.

OBJECTIVES: To analyze the motor evoked potential (MEP) responses to a degree of voluntary contraction and stimulus intensity and to suggest the standardized optimal stimulation for MEP responses. METHODS: MEPs induced by a cortical stimulation were elicited at the thenar muscles in 15 normal subjects during the rest and gradual voluntary contraction, using the 10% of maximal voluntary contraction (MVC), 30%, 50%, and MVC. During rest and during each contraction, excitability threshold at rest (RET) and at contraction (CET) were determined. Consecutive stimuli were applied, according to the intensity of ratio increment (110% to 150% of excitation threshold). RESULTS: The RET showed a remarkable decrease (57.1+/-8.2% --> 47.4+/-8.7%) after the voluntary contraction (P<0.05). Shortening of latency reached the saturation level with 10% of MVC, irrespective of stimulus intensity. Amplitude reached a saturation level at 30% of MVC with 62.7% intensity of maximal output, which is equal to 140% intensity of its CET, and to 110% of RET. MEP amplitude at rest and at 10% of MVC were influenced by the excitation threshold (P<0.05), but those at above 30% of MVC were not related. CONCLUSION: The procedure for optimal facilitation for the MEPs is as follows; for minimal latency of MEPs, minimal contraction (10% of MVC) with RET intensity is enough. For maximal amplitude of MEPs, moderate contraction (30% MVC) with 110% intensity of RET is adequate.

OBJECTIVES: This study was designed to measure sympathetic skin responses (SSRs) following magnetic stimulation of the cervicothoracic spine and to evaluate its clinical usefulness. METHODS: Fifteen healthy volunteers who had no dysautonomic symptoms or signs and a patient with C6 spinal cord transection participated in this study. To evoke SSR, we stimulated the C7 spinous process (SP) and T2 SP with 90 mm circular coil (Magstim 200). We recorded the sensory nerve action potential (SNAP) from the right middle finger to ascertain whether the C7 dorsal root was depolarized by the C7 SP stimulation. The same stimulation intensity by which SNAP had been obtained was used to evoke the SSR by the C7 and T2 SP stimulation. The recording of SSR was done in both palms. SNAP was recorded by the magnetic stimulation on the C7 SP in all subjects. RESULTS: By the C7 SP stimulation, the latency of SSR was 1.35 sec in the right palm, 1.33 sec in the left palm and by the T2 SP stimulation, the latency was 1.24 sec, 1.23 sec in order. The right-left difference was not found by each SP stimulation, but the latency of SSR by the T2 SP stimulation was faster than that by the C7 SP stimulation (p<0.01). The latency difference of C7 and T2 SP stimulation was 0.11 sec in the right palm, 0.10 sec in the left palm. In a case of C6 cord transection, SSR was evoked neither by the right median electric stimulation, nor by the C7 SP magnetic stimulation. However, SSR was successfully evoked by the T2 SP stimulation. CONCLUSION: We believe that the latency difference of C7 and T2 spinous process stimulation reflects the central conduction time of SSR.
