Spinopelvic Parameters as Risk Factors of Nonspecific Low Back Pain: A Case-Control Study.

Background: The effect of spinopelvic alignment on low back pain (LBP) incidence has been studied in many investigations. However, the interrelation between spinopelvic parameters and LBP is poorly understood. In particular, it is unknown whether particular patterns of spinopelvic parameters render nonspecific LBP.

A Study of Characteristic Features and Diagnostic Roles of X-ray and MRI in Calcifying Tendinitis of the Shoulder.

Calcifying tendinitis (CT) is an enigmatic lesion with several obscure aspects and it is a common disorder of the upper extremity characterized by the presence of calcifications in rotator cuff tendons and synovial tissues. In this study, we aimed to review the demographic and clinical characteristics, as well as radiologic and treatment history in CT patients who were referred with shoulder pain. In this cross-sectional study, a total of 146 patients who were referred with a shoulder CT were included.

Evaluation of Judet view radiographs accuracy in classification of acetabular fractures compared with three-dimensional computerized tomographic scan: a retrospective study.

Background: In the current diagnostic procedure, generally, both plain radiographs and 3D-CT scans are used for the diagnosis of acetabular fractures. There is no consensus regarding the value of a three-dimensional computerized tomographic (3D-CT) scan alone in the classification of acetabular fractures. In this study, we compared the accuracy of 3D-CT scan and plain radiography through the evaluation of their agreement with the intraoperative surgeon's classification.

Role of shoulder gradient in the pathogenesis of rotator cuff tears.

Background: Shoulder gradient has been associated with shoulder pathologies such as shoulder impingement syndrome.

Aim: To investigate if there is an association between shoulder gradient and incidence of rotator cuff tear (RCT).

Methods: A total of 61 patients with a confirmed diagnosis of RCT were included in this retrospective study.

Analysis of electrocautery smoke released from the tissues frequently cut in orthopedic surgeries.

Background: Electrosurgical smoke could be different by the device of cutting or the type of tissue that is being cut.

Aim: To analyze the electrocautery smoke released from the tissues that are frequently cut in orthopedic surgeries.

Methods: The released smoke from electrocautery of five different tissue types (meniscus, ligament, adipose, muscle, and synovium) of five patients who underwent total knee arthroplasty were collected and analyzed for volatile organic compounds (VOCs) and 27 candidate polycyclic aromatic hydrocarbons ( = 25).

Significant effect of simvastatin and/or ezetimibe-loaded nanofibers on the healing of femoral defect: An experimental study.

Background: Fracture healing complications are associated with significant healthcare and economic burden. In this study, we aimed to investigate how the combined administration of local simvastatin and ezetimibe into the femoral defect of the animal model affects the bone-healing process in comparison with their monotherapy.

Methods: A total of 32 four-month-old adult male Wistar rats were randomized into the four study groups: simvastatin + ezetimibe-loaded nanofibers (group 1), simvastatin-loaded nanofibers (group 2), ezetimibe-loaded nanofibers (group 3), and non-loaded nanofibers (group 4).

One-Bone Tarsus: A Case Report.

Tarsal coalition is a condition characterized by abnormal connections between ≥2 tarsi. Although tarsal coalition is not rare, tarsal coalitions involving >2 tarsi are very unusual. In this report, we describe a case of multiple tarsal coalitions in a 24-year-old male who experienced progressively worsening pain for 3 to 4 months before presenting for care.

Tailored treatment of aneurysmal bone cyst of the scapula: en bloc resection for the body and extended curettage for the neck and acromion.

Background: The acromion and neck of the scapula are essential components of shoulder function, but the body section is less critical. We treated aneurysmal bone cysts (ABCs) of the neck and ‏acromion with extended curettage and ABCs of the body with en bloc resection.‏ This article reports on local recurrence and the functional outcomes of this approach.

Evaluation of health-related quality of life after total hip arthroplasty: a case-control study in the Iranian population.

Background: As the total hip arthroplasty (THA) mainly aims to improve the quality of life of the patients, study of health-related quality of life (HRQoL) after THA has attracted much attention. Yet, the results considerably vary between studies. Here, we evaluate the HRQoL of the patient after THA, for the first time in the Iranian population.
