PURPOSE: To evaluate the functional outcome after surgical treatment for displaced fractures of proximal humerus and assess the final results according to surgical methods. MATERIALS AND METHODS: Thirty-three cases with follow-up over 12 months were divided into three groups: double tension band wiring (Group I, 14), plate fixation (Group II, 10) and closed reduction with internal/external fixation (Group III, 9). The pain index, the self-assessed functional score and the range of motion were obtained. RESULTS: Anatomical reduction was best obtained in group II and fractures united in 11-16 weeks. The pain index was worst in group III and the functional score of group I (80+/-12.2%) was higher than in the others (II: 69+/-15.7%, III: 55+/- 7.9%). The range of motion was worst in group III. Complications were noted in 9 cases, which occurred mostly in group II and III. CONCLUSIONS: Double tension band wiring in displaced proximal humerus fracture demonstrated that it provides a sufficient fixation for early rehabilitation and union, while minimizing complication

Authors studied the effects of cyciophosphamide, a potent inhibitor of nucleoprotein synthesis, to ivestigate the morphologic evidence of destructive actions to the hair. follicles. Sprague-Dawley rats were received 4 mg/kg of eyclophosphamide for 1 to 6 weeks, intraperitoneally, and examined light and electron microscopically. Light microscopically, distortion and constriction of the hair shafts, diminished diameter of the hair bulbs, and atrophy of. the hair matri.x were developed from 1 week. which were more prominent in second weeks and they were progressed after that time. Hairs were frequently fractured due to constriction of the hair shaf ts. Electron microscopically, cells of the hair pulp were decreased in number, and cells of the hair matrix were atrophied, Degenerative changes of the cellular organelles participating in grovth. and development of the hairs were noted, such as disordered formation of tricholyaline granules, diffuse atrophy and increased electron density of the inner root sheath, and loss of the glycogen and intercellular edema of the outer root sheath, but basal cells of the matrix showed minor changes relatively. From the above results, cyclophosphamide may specifically alter the matrix cells of the hair follicles and induces anagen hair losses, which may be reversible at a small dosage when the drug is discontinued, because basal cells of the matrix ahow rninor changes.

OBJECTIVES: In order to standardize the CRP, ESR and WBC count after three types of spinal surgery and get clinical usefulness from these laboratory dadas after spinal surgery and clincal usefulness of laboratory datas. MATERIAL AND METHODS: Three groups of patients(microdisectomy, anterior and posterior fusion) were chosen for the study. CRP, ESR and WBC levels were prospectively determined before surgery and at days 1-5, 10, 14,21 and 42 after surgery. RESULTS: In all patients, preoperative normal CRP level(<10mg/L) increased, reaching peak levels on the second day after anterior fusion(84.6mg/L), and at the third day after microdiscectomy(54.5mg/L) and posterolateral intercorporal fusion(152.2mg/L), with normalization in 5-10 days. Preoperative normal ESR level increased to peak level on the forth day after microdiscectomy(33.0mm/hr), and increased double peak levels after anterior(postoperative days 2&5) and posterolateral intercorporal fusion(postoperative days 3&5). ESR followed by a slow and irregular decrease, and at 42 days after surgery often remained elevated. WBC increased to variable peak level within normal limit in all patients. CONCLUSIONS: The rapid decline in CRP will probably be interrupted by a second rise or persisting elevation if infection occurs. CRP is presumably a better test than ESR for early detection of postoperative infection.

Stereotactic radiosurgery (SRS) is a technique to deliver a high dose to a target region and a low dose to a critical organ through only one or a few irradiation. The SRS must be planned exactly. Currently the surgery plan is performed by trial and error method. There are many questions about the reliability and reproducibility of the plan result. This study improve each step of the Oh's method based on heuristic target shaping to obtain the better result. The target was reconstructed using cylinders with same height and the neighbored cylinders were combined according to the difference of each center and diameter. Then, spheres were packed within each cylinders by the packing rules. Two virtual targets were used to compare this method with Oh's method. As a result, the numbers of isocenter were successfully reduced - more than 36% and 26% - without serious differences of prescription isodose to tumour volume ratio (PITV) and maximum dose to prescription dose ratio (MDPD). This technique using cylinder piling and sphere packing will be a helpful tool to planner in stereotactic radiosurgery.
