Orthopaedic wire has been used widely as a good internal fixator in cases of fracture, the ligament reconstruction, and for the stabilization of cervical spine. But if it is used inappropriately, a wire can be easy to fail by elongation, untwisting, or breakage. Among them, the most common failure of wire is breakage. To clarify the mechanism and the causes of wire failure, the authors analysed serial roentgenograms and scanning electronmicroscopic findings of broken wire in total 13 cases, which were experienced at the department of orthopaedic surgery, St. Mary's Hospital, Catholic University Medical College From January 1981 to December 1987. The results obtained were as follows :1. The mechanism of wire failure were classified into the 4 types ; minor continual flexing motion in 6 cases, repeated minor back and forth torsion in 1 case, tension failure in 2 cases and combined type in 4 cass. 2. The causes of wire failure were in appropriate use and inadequte application, a lack of s ufficient mechanical strength, micromotion due to inadequate postoperative imm obilization, early mobilization before tissue healing as well as certain injuries to the wire during handling in operation.

Plasma sprayed coating of the hydroxyapatite(HA) are biocompatible and may contribute to the early fixation of total joint prosthesis. We studied 64 hips(58 patients) who had hydroxyapatite coated primary total hip arthroplasty during the period from January 1992 to June 1993 about clinical and radiological result prospectively. The components have been followed for a minimum of 26 months and an average 31 months. Harris hip score averaged 92 at most recent follow up intervals. At the last follow up, the pain in 7 cases(11%) respectively and only slightly to mild in mostly. Although thigh pain has been occurred in 7 cases(11%), all patients had not trouble in daily activity. In radiological evaluation, there was a rapid and good endosteal bone formation of implants with bone apposition on the Gruen zone 2 and 6 of HA coating area. No radiolucent line formation was detected around HA coated area. In acetabular component, the endosteal bone formation was found in 12 cases and the radiolucent line was occurred in 4 cases. No revision were done for the femoral and acetabular component. The result of the study indicate that this hydroxyapatite coated component can provide satisfactory clinical and radiological result. Further prospective follow up is necessary to determine whether the favorable early result of this implant are maintained over longer period.

A 34 year-old woman was hospitalized with anterior chest pain and indigestion. Chest radiograph and computed tomogram revealed a sewing needle in the cardiac cavity. She had no histories of surgical intervention, drug abuse, or acupuncture. We removed the needle from the right ventricle under cardiopulmonary bypass.

CT was done 81 times on 63 proven malignant maxillary sinus tumors for 3 years from Feb.1979 to May 1982 atSeoul National University Hospital. Pre-treatment CT were 54 and post-treatment CT were 31 on 28 patient. Theresult were as follows; 1. The most frequent histopathologic diagnosis was 44 cases (69.8%) of squamous cellcarcinoma. Others were 5 cases (7.9%) of adenoid cystic carcinoma, 3 cases (4.8%) of olfactory neuroblastoma, 3cases (4.8%) of malignant lymphoma, 2 cases (3.2%) of melanoma, 2 cases (3.2%) of malignant fibrous histiocytoma,a rhabdomyosarcoma, a basal cell carcioma, a fibrosarcoma and a metastatic carcinoma from thyroid follicular adenocarcinoma. 2. The CT findings in 54 untreated malignant maxillary sinus tumors were sinus opacification, softtissue mass, and bone destruction in all cases. Other findings were fat plane obliteration (70%),osteosclerosis(59%), bone erosion and displacement (46%), low densities within soft tissue mass (27%), and airdensitis wiithin soft soft tissue mass (27%), and air densities within soft tissue mass(13%). 3. The value of pre-treatment CT in malignant maxillary sinus tumors were outlining the disease process especially soft tissuesuch as orbit, infratemporal fossa, pterygopalatine fossa, nasopharynx, pterygoid fossa and intracranialextension, and CT is the choice of diagnostic modality to determine the prognosis and the therapeutic planning insurgery and/or radiotherapy. 4. Post-treatment CT is also helpful to evalute the change in tumor size andpost-treatment complication.

PURPOSE: We reviewed the treatment outcomes and prognostic factors for patients with anal canal carcinoma who were treated with curative intent chemoradiotherapy (CRT) at Severance Hospital from 2005 to 2011. MATERIALS AND METHODS: Data for 38 eligible patients treated during this period were reviewed. All patients were treated with curative intent using radiotherapy (RT) with (n = 35) or without concomitant chemotherapy (n = 3). Among 35 patients who received CRT, most of the chemotherapeutic regimens were either 5-fluorouracil (5-FU) plus mitomycin C (23 patients) or 5-FU plus cisplatin (10 patients). Recurrence-free survival (RFS), colostomy-free survival (CFS), overall survival (OS), and locoregional control (LRC) rates were calculated using the Kaplan-Meier method and survival between subgroups were compared using the log-rank test. Cox's proportional hazard model was used for multivariate analysis. RESULTS: Over a median follow-up period of 44 months (range, 11 to 96 months), 3-year RFS, CFS, OS, and LRC were 80%, 79%, 85%, and 92%, respectively. In multivariate analysis, tumor size >4 cm was an independent predicting factor for poorer RFS (hazard ratio [HR], 6.35; 95% confidence interval [CI], 1.42 to 28.5; p = 0.006) and CFS (HR, 6.25; 95% CI, 1.39-28.0; p = 0.017), while the presence of external iliac lymph node metastasis was an independent prognosticator for poorer OS (HR, 9.32; 95% CI, 1.24 to 70.3; p = 0.030). No treatment-related colostomies or deaths occurred during or after treatment. CONCLUSION: Curative intent CRT resulted in excellent outcomes that were comparable to outcomes in previous randomized trials. No severe treatment-related toxicities were observed.
