Cross-cultural adaptation and validation of the Romanian Oxford Shoulder Score.

BACKGROUND: The use of validated patient reported outcome scores is critical to the reporting and monitoring of the effectiveness of clinical treatment. The aim of this study was to translate and culturally validate the English Oxford Shoulder Score (OSS) to Romanian. METHODS: Approximately, 125 patients with disorders of the rotator cuff and proximal humerus fractures completed the translated Oxford Shoulder Score (OSS_RO), the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and EuroQol 5-Dimension (EQ-5D-5L). The patients repeated the evaluation using the OSS_RO after 2 days. RESULTS: The OSS_RO had a high degree of internal consistency and reliability with a Cronbach's α of 0.954 at the initial completion and 0.945 at the second testing. The intraclass correlation coefficient (ICC, 2-way mixed effects model) was 0.953 (single measures) and 0.976 (average), P < .001. The OSS_RO was reproducible (Pearson's r = 0.953; P < .001). The OSS_RO was divergently valid with QuickDASH score (Pearson's r = -0.633 first and r = -0.672 second; P < .001) and convergent with the EQ-5D VAS (Pearson's r = 0.627 first and r = 0.640 second; P < .001) and the EQ-5D Index (Pearson's r = 0.759 first and r = 0.771 second; P < .001). CONCLUSION: Our study showed that the Romanian translation of the OSS is a reliable, reproducible and valid measure of shoulder function in patients with variable shoulder pathology.

Patient Specific Instruments for Complex Tumor Resection-Reconstruction Surgery within the Pelvis: A Series of 4 Cases.

The pelvis bone resection-reconstruction surgery is one of the most challenging fields in orthopedics. Being applied for tumors, as for other complex reconstruction cases, this type of surgery needs careful planning and is time consuming, in order to obtain proper accuracy. Unfortunately not all the time the expected accuracy is met, with consequences for the patients. PSI proved to provide good cutting accuracy during simulated tumor surgery within the pelvis. This article present a series of 4 patients operated in our department between June 2014 and Mars 2015 for tumors resectionreconstructions. The patients were imaged using a CT and an MRI scan and the images were reconstructed in 3D. According to the bone bank stock, the most similar allograft was chosen and the stored CT scan was reconstructed in 3D. Patient specific instruments (PSI) were designed and manufactured using rapid-prototyping technology for the resection of the native tissues as for the resection of the careful selected hemipelvic allografts. Allografts fitting to the pelvis of the patients was excellent and allowed stable osteosynthesis.
