From September 1983 to June 1988, the authors could experience 104 cases of meniscal injury from 99 patients by arthroscopic examination. The results of this study may be summarized as follows : 1. There were noticed 35 cases of medial meniscus tear, 35 cases of lateral discoid meniscus tear, 12 cases of intact lat discoid meniscus, 1 case of medial discoid meniscus and 3 cases of lateral meniscal cyst. 2. Most common type of meniscal tear was bucket handle type (35 cases, 34.6%). 3. Most common site of rupture was posterior horn of medial meniscus. 4. Post operative results appeared related with the type of meniscus rupture and combined pathology of knee jont. Bucket handle type rupture was of good prognosis and meniscus lesions with chondromalacia was of poor prognosis.

OBJECTIVE: The aim of this study was to examine 1) public knowledge and perceptions about attention-deficit hyperactivity disorder (ADHD) and 2) factors influencing the public's decisions to adhere to ADHD pharmacotherapy. METHODS: In this study, 396 participants responded to the internet survey regarding their experiences, beliefs and treatment preferences about ADHD. RESULTS: 252 respondents (63.6%) were reluctant to pharmacological treatment of ADHD. The respondents chose the functional impairment of the brain as the main cause of ADHD were favorable to pharmacological treatment and scored significantly high on the ADHD Knowledge Questionnaire. On the other hand, the respondents who regarded ADHD as an overly active personality rather than a disease were skeptical to pharmacotherapy and scored significantly low. The respondents who were acquainted with someone who had been diagnosed with ADHD perceived themselves relatively well informed about ADHD. However, the subjective perception of the degree of knowledge of ADHD was not correlated with the objective score of the ADHD Knowledge Questionnaire. CONCLUSION: The public is not well informed about ADHD and its treatments. Culturally appropriate psychoeducational strategies based on the media and the internet are needed. Providing biomedical conceptualization of ADHD to the public may aid with treatment decisions and promote adherence to pharmacological treatment.

PURPOSE: Articles reporting on the wear rate of polyethylene cup in hybrid THA are rare. So, we now report the results of wear rate of polyethylene in cementless Harris-Galante acetabular components and cemented Harris precoat femoral stem. MATERIALS AND METHODS: The cementless Harris-Galante acetabular components and cemented Harris precoat femoral stem of one-hundred hips in 71 patients were followed up for 2.5 ~ 7.5 years (mean 4.7 year) . The clinical results were evaluated by Harris hip score (HHS) and wear rates were measured using Livermore technique. RESULTS: The most recent follow-up of HHS was improved from 52 to 91 in average. The mean linear wear rate in cemetless acetabular component was 0.17 0.06mm/yr (range 0.05 ~ 0.35) . Two femoral components were revised for aseptic loosening and one acetabular component revised for aseptic loosening. Wear rate in the revision group was higher than mean wear rate. In chronological change of wear rate according to final follow up period, there was decreasing tendency for mean wear rate with time. There was no correlation found between mean wear rate and body weight. There was a decreasing tendency on mean wear rate with acetabular cup shell size and increasing tendency with level of activity. CONCLUSION: We concluded that cemented femoral stem was the reason for the trend in lower wear rate of polyethylene cup than which had been previously reported in cementless THA, but further follow-up studies will be needed to confirm that.

Femoral head fractures combined with hip dislocation are very rare injuries. In most cases, they result from high-energy trauma to the hip or lower extremity during traffic accidents. Various therapy options have been suggested to treat these injuries. Especially, different joint-preserving surgical options have been described for the treatment of traumatic osteochondral injury of the femoral head in young, active patients. In this report, we present a case that a traumatic osteochondral lesion to the femoral head after hip dislocation was treated with osteochondral autografts (OATS) from the non-weight-bearing area of the ipsilateral inferior femoral head through a surgical hip dislocation. After 1 year, the clinical and radiological outcome was satisfactory with no evidence of posttraumatic osteoarthritis and no pain of patients.

Infection with Toxocara canis evokes various symptoms by migration of the larva via hematogenic infiltration, but CNS involvement has rarely been documented. We describe a 63-year-old man who had eosinophilic myelitis associated with T. canis. He had subacute progressive lower body paresthesia. Spine MR revealed that the intramedullary lesion was in the thoracic cord. CSF analysis showed many eosinophils and elevated antibody titers to T. canis. These results indicate that parasitic infection should be considered as a possible cause of subacute myelitis.

Neck fracture is a major cause of death in traffic accidents and this injury pattern occurred normally in a frontal collision or overturn process. This study investigates a case of neck fracture from a low speed collision. In this case examined, the passenger in the front seat of the car was pulled back and did not have the seat belt on. As the vehicle slipped on a frozen road surface in a downward hill and crashed into the shoulder of the road at low speed. But strangely, even though his neck is fracture there were not any collision marks on interior of the car. This study applied computer simulation to analyze this case and we found out that the upper part of the person was rotated and raised at the time of collision and his neck was fully bent by interference with roof and we also know that the seat belt did not resist the passenger who pulled back his seat.
