BACKGROUND: Although several radiography-based systems for assessing skeletal maturity are available to clinicians, the classical Risser grading system remains a clinical gold standard. For scoliosis follow-up, a standing whole-spine radiograph is usually used. However, in our clinical practice, we have occasionally encountered cases in which ossification of the iliac crest is seen differently in the standing and supine whole-spine radiography. Here, we aimed to clarify the reliability of the Risser+ grading system for supine versus standing position radiographs...

BACKGROUND: The total number of spine surgeries per year and their related deaths in Japan has not been adequately estimated in the literature. METHODS: We retrospectively reviewed the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) between April 2014 to March 2021, which covers 99.9 % of health insurance claim receipts by general practitioners. The annual number of surgeries was counted using K codes, a procedure classification unique to Japan, and classified into the following six categories; percutaneous vertebroplasty, endoscopic surgery, open discectomy, laminoplasty/laminectomy, instrumentation surgery, and others...

BACKGROUND: Heterotopic ossification of large joints, such as knees and hips, has been reported after spinal cord injury, possibly leading to decreased activity of daily living due to a limited range of motion of the affected joint. Therefore, heterotopic ossification resection is performed to improve the range of motion, but it might cause massive bleeding as a complication. METHODS: In this case, the patient had a history of spinal cord injury and developed heterotopic ossification after the left hip injury...

BACKGROUND: Bone marrow edema (BME) in the acromioclavicular joint (ACj) may occur after arthroscopic rotator cuff repair (ARCR), resulting in persistent postoperative ACj pain. We investigated the incidence and clinical characteristics of BME in ACj after ARCR. METHODS: Patients exhibiting ACj-related symptoms prior to ARCR surgery, no BME in the ACj on MRI, and an ability to undergo 2-year postoperative physical and MRI examinations of the ACj were included. Patients who underwent distal clavicle resection or osteophyte resection below the ACj and those unable to achieve primary repair of the rotator cuff were excluded...

BACKGROUND: Total knee arthroplasty (TKA) is an effective treatment to improve mobility in patients with severe knee osteoarthritis. However, some patients continue to have poor mobility after surgery. The preoperative identification of patients with poor mobility after TKA allows for better treatment selection and appropriate goal setting. The purpose of this study was to develop a clinical prediction rule (CPR) to predict mobility after TKA. METHODS: This study included patients undergoing primary TKA...

JOURNAL ARTICLE
Yoshiaki Miyake, Toru Takagi
BACKGROUND: Antibiotic concentrations 100-1000 times higher than the minimum inhibitory concentration are necessary for eradicating biofilms in periprosthetic joint infections (PJI). Achieving this with intravenous antibiotics is challenging, but continuous local antibiotic perfusion (CLAP) can increase the local concentration of antibiotics. Although there are several reports on CLAP therapy in the fracture-related infection, there are only few reports on its application in PJI. Here, we report our experience with CLAP therapy for PJI...

BACKGROUND: The surgical treatment of periprosthetic femoral fracture (PFF) can be technically demanding and it is associated with high rates of complications and repeat surgery. However, repeat surgery is uncommon and few studies have examined survival and the functional prognosis following reoperation after the surgical treatment of PFF. We aimed to estimate the rate of reoperation for any reason, to determine the survival rate after reoperation for PFF, and to identify predictors associated with reoperation after PFF surgery in a multicenter (TRON group) study...

BACKGROUND: Previous studies have demonstrated that the point prevalence of back pain ranges from 12 % to 33 % and that the lifetime prevalence of back pain ranges from 28 % to 51 % in adolescents. However, few studies on back pain in patients with Adolescent idiopathic scoliosis (AIS) have been conducted, and these studies had significant limitations, including a lack of comparative controls and detailed information about scoliotic deformity or pain location. This study aimed to determine whether adolescents with AIS experience back pain in specific regions...

JOURNAL ARTICLE
Nikolay Dimitrov, Tsvetan Tsenkov
PURPOSE: The adopted treatment for chronic elbow PLRI is lateral ulnar collateral ligament reconstruction. However, the most frequently reported complication after primary reconstruction is recurrent instability - up to 25 %. It was thus hypothesized that enhancing the secondary stabilizers will provide successful results with a lower rate of recurrent instability in comparison to techniques with primary reconstruction only. This study aimed to demonstrate a novel surgical technique involving secondary stabilizers...

BACKGROUND: Extracorporeal shock wave therapy (ESWT) is an effective treatment for musculoskeletal pain, tendinopathy, and fasciitis with an anti-inflammatory effect. ESWT can be categorized into two groups: radial pressure wave (RPW) and focused shock wave (FSW). Although there have been several studies on the inflammation and pain-improvement mechanisms of FSW, there are few studies on the pain-improvement mechanisms of RPW. This study aimed to elucidate the efficacy of RPW in a rat model of adjuvant arthritis...

BACKGROUND: The Bristow procedure has been shown to be a reliable method to prevent recurrent anterior shoulder instability by compensating for glenoid bone loss and producing the sling effect. The degree of postoperative morphological change in the coracoid bone graft is speculated to influence glenohumeral joint stability; however, the details of these changes after the Bristow procedure remain unknown. This study was performed to quantify the postoperative change in the coracoid bone graft volume as assessed by three-dimensional computed tomography (3D-CT)...

BACKGROUND: This study aimed to morphologically and histologically examine whether pig is useful as models for rotator cuff tear (RCT). METHODS: The morphology of the scapula and humerus bones was evaluated by taking X-ray and three-dimensional computed tomography (3D CT) scans of the right shoulders of five female pigs (age: 4 months). The rotator cuff (RC) footprint at the humeral insertion of these was observed and its shape was measured. Next, they underwent general anesthesia and an acute rotator cuff tear/rotator cuff repair (RCT/RCR) model was created using a deltoid split approach...
