Objective: To describe the translation and cultural adaptation of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire into Brazilian Portuguese, and verifies the reliability and validity of this new version.

Methods: A cross-cultural adaptation of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire was performed using the following steps: translation, back-translation, committee review, and pre-testing phase (50 subjects). The psychometric properties were evaluated by application of the questionnaire to 102 patients. Reliability was assessed by homogeneity and stability of measures. The criterion-related validity was tested by comparing scores of Japanese Orthopaedic Association Back Pain Evaluation Questionnaire to Oswestry and Medical Outcomes Study 36 - Item Short questionnaires.

Results: Excellent internal consistency was found in both test (Cronbach's α of 0.90) and re-test (Cronbach's α of 0.91). The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire showed good reliability and the correlations ranged from reasonable (0.64) to very good (r=0.91).

Conclusion: The Brazilian Portuguese version of Medical Outcomes Study 36 - Item Short was easy to apply and understand. The questionnaire had a great impact on assessment and multidimensional care of patients with low back pain.

Objective: Cervical spondylotic myelopathy (CSM) shows varying levels of improvement after surgical treatment. While some patients improve soon after surgery, others may take months to years to show any signs of improvement. The goal of this study was to evaluate postoperative improvement, patient-reported outcomes, and patient satisfaction up to 2 years after surgical treatment for CSM, which will help optimize the current treatment strategies and effectively manage patient expectations.

Background And Purpose: Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord (SC) dysfunction. In routine clinical practice, SC changes are well depicted using conventional MRI, especially T2-weighted imaging. However, this modality usually fails to provide satisfactory clinico-radiological correlations.

Surgical outcomes of radial polydactyly according to a modified Wassel-Flatt classification: A retrospective study of 211 patients with 223 thumbs.

J Hand Surg Eur Vol

January 2025

Department of Orthopedic Surgery, Asan Medical Center, University of Ulsan College of Medicine, 88, Olympic Road 43-gil, Songpa-gu, Seoul, 05505, Republic of Korea.

We previously introduced the modified Wassel-Flatt classification to overcome the limitation of the traditional classification for radial polydactyly. This study aimed to evaluate this modified classification in terms of surgical planning and clinical outcomes using the Japanese Society for Surgery of the Hand scoring system. A retrospective review of 211 patients with 223 thumbs treated for radial polydactyly between October 2017 and November 2022 was conducted.

Background: According to the conventional postoperative procedure after total ankle arthroplasty (TAA) for end-stage osteoarthritis (OA) and rheumatoid arthritis (RA), mobilization and weight-bearing are currently started after completion of wound healing. Recently, an early rehabilitation program after cemented TAA with a modified anterolateral approach has been attempted because this approach could provide stable wound healing. To investigate the possibility of expediting rehabilitation, this study evaluated the feasibility, safety, and universality of an early rehabilitation program after cemented TAA using a modified anterolateral approach, even when a surgeon was completely changed.

Implant failure of the Compress prosthesis: a case report.

J Med Case Rep

January 2025

Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine, Nagoya University Hospital, 65 Tsurumai, Showa, Nagoya, Aichi, 466-8550, Japan.

Background: The Compress is designed to achieve bone formation and stability by applying pressure at the bone-implant interface, minimizing the likelihood of aseptic loosening, which is a complication of stem implants. Herein, we report two cases of implant failure using the Compress.

Case Presentation: Case 1 describes a 36 year-old Japanese man who underwent extraarticular tumor resection, Compress arthroplasty, and reconstruction with a gastrocnemius flap after preoperative chemotherapy for a secondary malignant giant cell tumor in the right distal femur.
