BACKGROUND: Atypical femoral fractures (AFFs) have been reported to occur in patients with bone metastases who received long-term bisphosphonate treatment. However, the incidence of AFFs in breast cancer patients with bone metastases who received intravenous bisphosphonate is unclear. The purpose of this study is to examine the incidence of AFFs in breast cancer patients with bone metastases who received intravenous bisphosphonate. In addition, we estimated the number of dose and duration of intravenous bisphosphonate at the time of occurrence of AFFs...

OBJECTIVES: There are not many chances to arthroscopically reassess how graft tunnel malpositions in primary anterior cruciate ligament reconstruction (ACLR) associate with intra-articular degeneration in revision ACLR. This study was aimed to evaluate whether radiographic tunnel position in primary ACLR affect cartilaginous changes and bucket-handle meniscus tears in revision ACLR. METHODS: Thirty-five patients who underwent revision ACLR were recruited; their primary surgeries were single-bundle reconstructions...

BACKGROUND: Osteoporotic vertebral fractures (OVFs) are the most common cause of intractable back pain and reduced activities of daily living (ADL), which may affect cognitive function. However, no previous studies have reported a change in cognitive function after OVFs. The purpose was to reveal cognitive function changes after OVFs and investigate the risk factors for cognitive decline. METHODS: Consecutive patients with symptomatic OVFs were enrolled in a prospective multicenter cohort study...

BACKGROUND: Symptomatic skeletal events (SSEs) affect many patients with bone metastases from breast cancer. However, predictive models of SSEs in patients with bone metastases from breast cancer have not been established for clinical use. The purpose of this study is to examine risk factors for SSEs in those patients and by combining these risk factors patients are classified into several groups. With this risk-stratification model, we can identify patients at higher risk of SSEs and require close follow-up to maintain ADL...

BACKGROUND: In this study, we investigated the responsiveness of the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) for patient's assessment before and after hallux valgus surgery. METHODS: Patient-reported answers on the SAFE-Q and Short Form-36 (SF-36) before and at a mean of 3-4 and 9-12 months after hallux valgus surgery were analyzed. Data of 100 patients (92 women, eight men) from 36 institutions throughout Japan were used for analysis. RESULTS: In all subscales of the SAFE-Q, the trend of increased scores after surgery was statistically significant (P < 0...

OBJECTIVES: The objective of this retrospective study was to investigate the prevalence of asymptomatic deep vein thrombosis (DVT) and the risk of DVT in patients admitted to hospital for total knee arthroplasty (TKA). METHODS: From September of 2003 to December of 2013, 322 patients admitted for TKA were eligible for this retrospective study. A diagnosis of DVT was confirmed by Doppler ultrasonography. The prevalence of silent DVT in the lower limbs in patients before TKA was assessed...

BACKGROUND: Despite recommendations on how to prevent baseball injuries in youths by the Japanese Society of Clinical Sports Medicine, shoulder and elbow pain still frequently occurs in young baseball players. We conducted a questionnaire survey among baseball players at elementary schools across the country to understand the practice conditions of players, examining the risk factors of shoulder and elbow pain in baseball players. METHODS: The questionnaire survey was conducted among elementary school baseball players as members of the Baseball Federation of Japan in September 2015...

BACKGROUND: Residual leg numbness (LN) following lumbar surgery can lower patient satisfaction; however, prospective studies are sparse. The purpose of this study was to evaluate recovery from LN following decompression surgery for lumbar spinal stenosis (LSS). METHODS: A total of 145 patients with LSS were enrolled. All patients underwent decompressive surgery, with or without spinal fusion, followed by a 12 month prospective follow-up. The degree of LN and leg pain (LP) was assessed using the visual analog scale (VAS), a patient-reported outcome measure...

BACKGROUND: Lumbar disc degeneration (LDD) is known to be the main cause of low back pain, although it is unclear how or when LDD progresses. The purpose of this study was to clarify the process and features of LDD progression in young women. METHODS: We enrolled 480 nursing students and carried out a prospective cohort study in 84 nursing students. MRI of the lumbar spine was taken once during their time as a student and again at 9.8 years (7-14) after the first MRI when they were working as nurses...

AIMS: The common treatment for an undisplaced femoral neck fracture is osteosynthesis. Two major complications of osteosynthesis are non-union and late collapse of the femoral head. We speculated that femoral head perfusion is one of the most important factors that affect the outcome of osteosynthesis after femoral neck fracture. We have preoperatively estimated femoral head perfusion by dynamic MRI positive enhancement integral color mapping (PEICM). The purpose of this study was to evaluate the outcomes of undisplaced femoral neck fractures based on PEICM...

BACKGROUND: There is no data available on the radiographic development of the Scheuermann's deformity. Our purpose was to investigate radiographic deformity progression and the relation between kyphosis progression and clinical outcome in patients with untreated Scheuermann's kyphosis. METHODS: Thoracic kyphosis (Th4-Th12) was measured from standing lateral radiographs in 19 patients at baseline and after mean 46-year follow-up. Mean age at baseline was 19.2 and at follow-up 64...

BACKGROUND: The Japanese Orthopedic Association designed their back pain evaluation questionnaire (JOABPEQ) which was proven to be feasible, reliable and valid. The questionnaire's validity and reliability were confirmed when it was implemented in patients with different cultural background. Since the JOABPEQ still has not been utilized in any of the Arabic countries, we present the Arabic version with its validity and reliability. METHODS: After ensuring an optimal forward-backward translation of the JOABPEQ, the Arabic version was distributed among 151 patients visiting our clinics from December 2015 to February 2016...

BACKGROUND: The posterior root ligament of the medial meniscus (MM) has a critical role in regulating the MM movement. An accurate diagnosis of the MM posterior root tear (MMPRT) using magnetic resonance imaging (MRI) is important for preventing sequential osteoarthritis following the MMPRT. However, diagnosis of the MMPRT is relatively difficult even after using several characteristic MRI findings. The aim of this study was to identify a useful meniscal body sign of the MMPRT for improving diagnostic MRI reading...

BACKGROUND: Optimal treatments of patients aged >40 years with osteosarcoma and Ewing sarcoma and of patients with other types of bone sarcoma have not yet been established. METHODS: The clinical characteristics of 746 patients with primary bone sarcomas aged >40 years listed in the nationwide tumor registry (Bone and Soft Tissue Tumor Registry of Japan) were investigated. Patients with Ewing sarcoma, conventional chondrosarcoma, multiple myeloma, and malignant lymphoma were excluded...

BACKGROUND: Quadriceps muscle strength reference value of normal individuals in Japan is necessary to quantitatively evaluate functional deterioration of locomotive organs. Therefore, we established a reference value by using the Locomo Scan, a new device that measures knee extension muscle strength. METHODS: We measured knee extension muscle strength with the Locomo Scan in 3617 individuals (1692 men, 1925 women, 20-89 years; mean age. 50.7 years) by implementing our own 49 measurement events in 20 prefectures...
