This article reports on factors affecting the postoperative results in cubital tunnel syndrome. We evaluated 111 limbs of 107 patients who had been surgically treated for cubital tunnel syndrome. Average patient age was 43.9 years (range: 11-77 years). Postoperative follow-up ranged from 1 to 17 years (mean: 5.2 years). Causal diseases included cubitus(More)
The present study was undertaken to identify the factors responsible for hip joint dislocation after total hip arthroplasty, laying emphasis on analysis of the background variables of the patients. Of the 317 hips included in the study, ten (3.2%) dislocated. Only the anteversion angle of the cup differed significantly between the dislocation group and the(More)
To evaluate the clinical efficacy of mechanical thromboprophylaxis after elective hip surgery, we reviewed 3016 patients who underwent hip surgery at 5 centers. Primary total hip arthroplasty (THA), revision THA, and pelvic or femoral osteotomies were performed in 2648, 298, and 70 patients, respectively. Epidural anesthesia, intraoperative calf bandage,(More)
Myxoid liposarcomas (MLSs) are characterized by t(12;16)(q13;p11) translocation and expression of TLS-CHOP chimeric oncoprotein. However, the molecular functions of TLS-CHOP have not been fully understood. On the other hand, microRNAs (miRNAs) comprise an abundant class of endogenous small non-coding RNAs that negatively regulate the expression of their(More)
This study examined the mid-term (more than 5 years) results of cementless total hip arthroplasty (THA) using Biomet acetabular cups (locking mechanism: Hexloc type or Ringloc type). A series of 58 patients (70 hips) who had undergone cementless THA at our department were available for inclusion in this study. The average age at surgery was 55.2 years, and(More)
We treated a combined fracture of the greater and lesser tuberosity with head shaft continuity in the proximal humerus. This case is impossible to classify in three of the classifications, the Neer classification, AO Müller classification, or Jakob classification. However, this case has been described as fracture types in two different categories in the(More)
Alumina-on-alumina hip implants with microseparation were run in a hip simulator for comparison of the nonseparation simulator mode and retrievals. The 28-, 32-, and 36-mm Biolox-forte implants were run to 5 million cycles with the use of 50% newborn calf serum. Howmedica Osteonics Trident cups with titanium backing were used in all sets. In standard (STD)(More)
The fusion oncoproteins, TLS-CHOP and EWS-CHOP, are characteristic markers for myxoid and round cell liposarcomas (MLS/RCLS). Especially, the peptide sequence of 26 amino acids corresponding to the normally untranslated CHOP exon 2 and parts of exon 3 (5'-UTR) is a unique structure for these chimeric proteins. In this report, we have generated monoclonal(More)
Accurate reproduction of anatomic relationship is important in non-constrained prosthetic arthroplasty. The accurate lateral glenohumeral offset, which indicates a parameter of the lever arm of the deltoid and supraspinatus muscles, is one of the most important elements in achieving the efficient shoulder functions after prosthetic reconstruction. However,(More)
The patient was a 12-year-old girl with linear scleroderma distributed on the right abdomen, dorsal aspect of the right thigh, lower leg and foot. The initial regimen of oral prednisolone and methotrexate, or i.v. methylprednisolone failed in the treatment of the scleroderma. Then bath psoralen and ultraviolet A therapy (bath-PUVA) therapy of 0.2 J-4.0(More)
