Randomized Controlled Trial Comparative StudyClinical outcome after Chevron-Akin double osteotomy versus isolated Chevron procedure: a prospective matched group analysis.
Hallux valgus is a frequent condition of the forefoot, resulting in cosmetic deformity and pain. Chevron osteotomy (CO) is widely employed for the treatment of hallux valgus. Chevron-Akin double osteotomy (CAO) was previously described and superiority over an isolated Chevron procedure was assumed. The objective of this study was to compare the short-to-middle term outcomes of CO and CAO. ⋯ These findings indicate that Chevron-Akin double osteotomy is a save and practicable procedure for the treatment of mild-to-moderate hallux valgus. Superiority of combined Chevron-Akin procedure over an isolated Chevron osteotomy might be limited to distinct clinical settings, but should not be generally assumed.

Cross-cultural adaptation and validation of the Korean version of the Oxford shoulder score.
The Oxford shoulder score (OSS) is being used increasingly and has been adapted cross-culturally in some Western countries. On the other hand, there are few validated translations of the OSS in Asian countries. This study translated and adapted cross-culturally the original OSS to produce a Korean version, and assessed the validity and reliability of the Korean version of the OSS (Korean OSS). ⋯ The Korean OSS proved to be valid by demonstrating a significant correlation with the patient-based upper extremity questionnaire and clinical assessment. The application and evaluation of the instrument is feasible and understandable among patients in Korea.

Comparative StudyAngle stable locking nails versus conventionally locked intramedullary nails in proximal tibial shaft fractures: a biomechanical study.
A tibial nail with fixed-angle locking screws intends to combine the advantages of angular stability and intramedullary stabilization in extraarticular proximal tibial fractures. The goal of this study is to analyze if the angle stable tibial nail (ASN) is biomechanically more stable than an established conventional standard nail (CN). ⋯ No significant difference in stability between the two compared implants could be demonstrated. A trend could be shown indicating that the rate of nail loosening in the proximal osteotomized part of the bone was lower for the angle stable nail. This trend, however, could not be substantiated statistically.

Octenidine in combination with polymethylmethacrylate: a new option for preventing infection?
Orthopedic implant infections represent a serious complication for both patient and surgeon. In order to minimize this risk, it has become standard practice in surgery and orthopedics to add antimicrobial substances to the polymethylmethacrylate (PMMA) bone cement. The aim of this study is to find new options for preventing infection by using alternative adjuvants in combination with PMMA. We hypothesized, that Octenidine, after being combined with PMMA, can be released in vitro and an antimicrobial efficacy of discharged Octenidine can be shown. ⋯ These results suggest that Octenidine is released after combining it with PMMA and reaches working concentrations in vitro. These findings suggest a new and effective alternative for prevention of infection in cemented implants. Further investigations on the biocompatibility of this combination is needed.

Randomized Controlled Trial Comparative StudyClosed suction drainage with or without re-transfusion of filtered shed blood does not offer advantages in primary non-cemented total hip replacement using a direct anterior approach.
Wondering if the use of drains allowing re-transfusion of shed blood as opposed to closed suction drains or no drains would improve quality of care to patients undergoing simple non-cemented primary total hip replacement (THR) using a direct anterior approach, a three-arm prospective randomized study was conducted. ⋯ The possibility to re-transfuse drained blood was not an argument for using drains and, accepting more thigh swelling, we stop to use drains in simple non-cemented primary THR using the direct anterior approach.
