Backgroud: Many studies have reported injury characteristics of individual traumatic situations. However, a comparative analysis of specific risks is meaningful to better understand injury characteristics and help establish injury-prevention measures. This study was conducted to investigate and compare injury characteristics in children and adolescents by various outdoor traumatic situations.

Methods: We retrospectively studied 30 patients who underwent ODLLM. Clinical evaluations were performed using a visual analog scale (VAS), Japanese Orthopaedic Association (JOA) score, and Neck Disability Index (NDI) preoperatively, at 1 year postoperatively, and at the last follow-up.
Background: We aimed to evaluate the effect of vitamin D levels on the functional outcome of elderly women who underwent total knee arthroplasty (TKA).
Methods: Seven hundred and four patients (1013 knees) who underwent primary TKA were included in our retrospective study. Preoperative vitamin D levels were measured and the relationship analyzed between these and age, weight, height, body mass index, and bone mineral density.
Objective: To evaluate and compare the clinical and radiographic features of 25 patients with infectious spondylitis treated with anterior debridement and reconstruction using autogenous bone grafts vs. a metal cage with allogenic bone grafts.
Methods: The study analyzed 25 patients diagnosed with infectious thoracolumbar spondylitis who underwent anterior radical debridement and reconstruction.
Background: Whether surgery should be performed after excisional biopsy based on mammography or magnetic resonance imaging (MRI) findings has not been evaluated for breast cancer with suspicious microcalcifications on mammography. This study investigated the ability of mammography and MRI to predict residual malignancy after excisional biopsy for suspicious microcalcifications and whether background parenchymal enhancement (BPE) influences the diagnostic performance of MRI.
Patients And Methods: Fifty-one patients with breast cancer who underwent excisional biopsy for suspicious microcalcifications between January 2009 and February 2019 were enrolled in this single-center retrospective study.
Objective: Minimal data exist regarding non-operative management of suspected pseudarthrosis after pedicle subtraction osteotomy (PSO). This study reports radiographic and clinical outcomes of non-operative management for post-PSO pseudarthrosis at a minimum 5 years post-detection.
Methods: Nineteen consecutive patients with implant breakage indicating probable pseudarthrosis after PSO surgery (13 women/ six men; mean age at surgery, 58 years) without severe pain and disability were treated with non-operative management (mean follow-up, 5.
Complex comminuted fractures involving the distal tibia, ankle joint, and talus are often accompanied by bone loss and are highly prone to complications such as soft tissue infection, fixation failure, and posttraumatic arthrosis, with joint reconstruction being difficult in cases with severe joint destruction or bone loss. In this case, bone transport and fusion procedures were performed to treat a patient with an open fracture involving total talar dislocation, talar bone loss, and distal tibial bone loss. Just as in this case, where the surrounding soft tissues remain healthy, limb salvage via segmental bone transport may be a reasonable option in fractures with massive bone loss that include joints.

Methods: Synovial fluid was obtained from 44 knees of 40 patients. The Kellgren-Lawrence (KL) grade was measured using radiograph.
Background: Selective soft tissue release (SSTR), which includes a combination of abductor hallucis, tibialis posterior, and Achilles lengthening, has been used in patients with recurrent clubfoot deformity after Ponseti treatment. The aim of this study was to investigate the prognostic factors for recurrence of clubfoot deformity after SSTR.
Methods: Consecutive patients with idiopathic clubfoot and residual or recurrent deformity after Ponseti treatment underwent SSTR between 2005 and 2013.
Background: Morton's neuroma is one of the common causes of forefoot pain. In the present study, hyaluronic acid injection was performed on patients to determine the efficacy and adverse effects of hyaluronic acid in management of Morton's neuroma.
Methods: Eighty-three patients with Morton's neuroma in their third intermetatarsal space with definite Mulder's click were included in the study.
Background: Recurrence of glenohumeral dislocation after arthroscopic Bankart repair can be associated with a large osseous defect in the posterosuperior part of the humeral head. Our hypothesis is that remplissage is more effective to prevent recurrence of glenohumeral instability without a severe motion deficit.
Methods: Engaging Hill-Sachs lesions were observed in 48 of 737 patients (6.
