Developmental dysplasia of the hip (DDH) is a common musculoskeletal disorder characterized by progressive joint soreness and limited mobility. The aim of the present study was to investigate the pathological changes and inflammatory infiltration in the hypertrophic synovium of the hip joint associated with the progression of DDH. Synovial biopsies in the hip joint are obtained from patients with moderate DDH and severe DDH during surgery. These biopsies are processed for histological and immunohistochemical (IHC) analysis and investigation of the pathological processes in a synovium, including types of inflammatory cell infiltration, synovial angiogenesis and fibrosis, neuron endings and neuropeptide invasion...

Introduction: Periprosthetic humeral shaft fracture after total elbow arthroplasty (TEA) and open reduction and internal fixation at the same side humeral neck fracture in patients with osteoporosis poses a treatment challenge. Herein, we describe our experience with its treatment using the Ilizarov external ring fixator. Case Report: A 74-year-old Japanese woman with rheumatoid arthritis and osteoporosis sustained a periprosthetic humeral shaft fracture. The fracture was externally fixated with the Ilizarov external ring fixator, and five wires (Orthofix, Lewisville, Texas) were inserted just beside the components of the TEA (three wires were beside the humeral component and two wires the ulnar component)...

BACKGROUND AND OBJECTIVES: A substantial group of patients suffer from moderate to severe pain following elective total hip arthroplasty (THA). Due to the complex innervation of the hip, peripheral nerve block techniques can be challenging and are not widely used. Since the obturator nerve innervates both the anteromedial part of the joint capsule as well as intra-articular nociceptors, we hypothesized that an obturator nerve block (ONB) would decrease the opioid consumption after THA...

BACKGROUND: Clavicle fractures are common, accounting for 2.6% to 4% of all fractures. Eighty per cent of clavicle fractures are located in the middle third of the clavicle. Although treatment of these fractures is usually non-surgical, displaced clavicle fractures may be considered for surgical treatment because of their greater risk of non-union. This is an update of a Cochrane Review first published in 2013. OBJECTIVES: To assess the effects (benefits and harms) of surgical versus conservative interventions for treating middle third clavicle fractures...

Background: Static and dynamic postures of lumbopelvic in low back pain (LBP) are considered as two important aspects of clinical assessment and management of LBP. Thus, the focus of the current study was to compare the posture and compensatory strategy of hip and lumbar region during trunk flexion between LBP subgroupsand health subjects. LBP cases are subdivided into active extension pattern (AEP) and flexion pattern (FP) based on O'Sullivan's classification system (OCS). Methods: This work was a cross-sectional study involving 72 men, 21 low back pain patients with FP and 31 low back pain patients with AEP and 20 healthy groups...

Chronic low-back pain (CLBP) has an increasing incidence and yields a tremendous health economic burden. There are different anatomic structures that may be responsible for CLBP, such as lumbar intervertebral discs, sacroiliac joints, nerve root dura, fascia, ligaments, and muscles. However, to a large extent, CLBP is associated with structural changes in and around the facet (zygapophyseal) joint. If conservative treatment strategies fail, symptoms and pain can effectively be reduced by denervation or rhizotomy of the medial branch of the dorsal ramus of the spinal nerve through radiofrequency ablation...

INTRODUCTION: The objective of this video is to highlight strategies to improve operating room (OR) ergonomics, which will result in increased surgeon comfort during minimally invasive gynecologic surgery and decreased risk of musculoskeletal injury. METHODS: Work-related musculoskeletal disorders (WMSDs) are prevalent among surgeons, including those who perform minimally invasive gynecologic surgery. WMSDs are repetitive strain injuries that can damage a surgeon's muscles, nerves, and/or joints and commonly affect the neck, back, wrist, and hands...

Irritable bowel syndrome (IBS) is one of the most debilitating and common gastrointestinal disorders; nevertheless, its pathophysiology is still unclear. It affects 11% of the world's population, and is characterized by alternating periods of pain and/or motility disorders with periods of remission and without any evidence of any structural and functional organic variation. It has been recently proposed that an altered contractile ability of the diaphragm muscle might adversely influence intestinal motility...

Background: The olecranon osteotomy-facilitated elbow release (OFER) is a safe and effective method for releasing severe posttraumatic elbow contractures. The OFER procedure is easier, faster, and relatively less invasive, and appears to offer superior outcomes, compared with more traditional techniques. Description: An olecranon osteotomy provides a trapdoor through which the surgeon will have circumferential access to the joint and will be able to address all intrinsic and extrinsic causes of contracture...

Background: Sensory neurons play an essential role in almost all pain conditions, and have recently been classified into distinct subsets on the basis of their transcriptomes. Here we have analysed alterations in dorsal root ganglia (DRG) gene expression using microarrays in mouse models related to human chronic pain. Methods: Six different pain models were studied in male C57BL/6J mice: (1) bone cancer pain using cancer cell injection in the intramedullary space of the femur; (2) neuropathic pain using partial sciatic nerve ligation; (3) osteoarthritis pain using mechanical joint loading; (4) chemotherapy-induced pain with oxaliplatin; (5) chronic muscle pain using hyperalgesic priming; and (6) inflammatory pain using intraplantar complete Freund's adjuvant...

BACKGROUND AND OVERVIEW: Orofacial pain has multifactorial causes and is often a diagnostic challenge. Misdiagnosis can result in morbidity or mortality due to misdirected and inappropriate treatment. A delay of necessary treatment, in cases of ominous illnesses, may result in its perpetuation or progression. The authors present a case report that illustrates these possibilities. CASE DESCRIPTION: This case report describes a 36-year-old woman with the chief symptom of painless, limited mandibular movement...

We present the movement control approach as part of the treatment-based classification system. This approach proposes a movement control schema that clarifies that movement control is a product of the interplay among multiple biopsychosocial components. The schema illustrates that for movement to occur in a dynamically controlled fashion, the lumbar spine requires both local mobility and global stability. Local mobility means that the lumbar spine and its adjacent regions possess adequate nerve and joint(s) mobility and soft tissue compliance (ie, the malleability of tissue to undergo elastic deformation)...

BACKGROUND: Patients with any type of temporomandibular disorder (TMD) may have several symptoms in their temporomandibular joints, masticatory muscles and associated structures, and may have otological symptoms such as tinnitus, ear fullness, ear pain, hearing loss, hyperacusis, and vertigo, which may be due to the anatomical proximity between the temporomandibular joint, muscles innervated by the trigeminal nerve, and ear structures. Objective: This study found a prevalence of ear complaints described in the medical records of patients (n = 485) at the Center for Diagnosis and Treatment of the Temporomandibular Joint and Dental-Facial Functional Alterations at Tuiuti University of Paraná (CDATM/UTP), with TMD evaluated by the Research Diagnostic Criteria/Temporomandibular Disorders (RDC/ TMD)...

There is a high medical need to improve the effectiveness of the treatment of pain and traumatic soft tissue injuries. In this context, electrostimulating devices have been used with only sporadic success. There is also much evidence of endogenous electrical signals that play key roles in regulating the development and regeneration of many tissues. Transepithelial potential gradients are one source of the direct current (DC) electrical signals that stimulate and guide the migration of inflammatory cells, epithelial cells, fibroblasts and mesenchymal stem cells to achieve effective wound healing...
