BACKGROUND: According to improved functional outcome and life expectancy in orthopaedic oncology patients, there has been a growing interest in not only oncologic and functional outcomes but also health-related quality of life (HRQOL), including body image, mental status, or social activities, after surgery. However, there has been a lack of disease-specific measures focusing on the ability of orthopaedic oncology patients to evaluate their HRQOL comprehensively. Therefore, our aims in the present study were 1) to develop a patient-oriented disease-specific outcome measure of HRQOL for musculoskeletal oncology patients (COMMON-LE), and 2) to examine the practical applicability, reliability and validity of the COMMON-LE for patients with musculoskeletal tumors in the lower extremity...

BACKGROUND: In infant poliomyelitis or poliomyelitis-like paresis, there has been no means of treating residual paralysis and the policy has been to wait until an affected infant has grown sufficiently to enable tendon transfer or arthrodesis. However, recent reports have described relatively good results for early surgical intervention in the form of nerve transfer. METHODS: In a 4-year and 6-month-old child we transferred a partial ulnar nerve for elbow flexor reconstruction even 3 years and 10 months after the onset of poliomyelitis-like palsy and also transferred partial accessory and radial nerves for shoulder function restoration 6 months after the first operation...

BACKGROUND: Due to concern of potential metallosis caused by residual microscopic ceramic particles, metal-on-metal (MoM) bearing is deemed undesirable in revision total hip arthroplasty (THA) for ceramic bearing fracture. We determined whether MoM bearing is suitable to be used in revision THA for ceramic fractures and also evaluated whether this treatment increases serum iron levels compared with MoM bearing revision THA for polyethylene failure. METHODS: Between 2006 and 2012, 22 patients underwent revision surgery using MoM bearing (28 mm femoral head in 18 hips and 32 mm in 4 hips) for ceramic bearing fracture and followed average 52...

BACKGROUND: We have developed iodine-supported titanium implants, which were shown to have good anti-bacterial effects for Methicillin-sensitive Staphylococcus aureus (MSSA) in our past basic research. However, PJI can be caused by various bacteria including MRSA, Pseudomonas aeruginosa, MSSE, and fungus. The purpose of this study was to investigate whether these implants also have good antibacterial attachment effects for MRSA, P. aeruginosa, MSSE, and fungus. METHODS: Ti-6Al-4V titanium plates were either left untreated (Ti), treated with oxide film on the Ti surface by anodization (Ti-O), or treated with an iodine coating on oxidation film (Ti-I)...
