INTRODUCTION: Advances in radiological imaging techniques have enabled volumetric measurements of meningiomas to be easily monitored using serial imaging scans. There is limited literature on the relationship between tumour growth rates and the WHO classification of meningiomas despite tumour growth being a major determinant of type and timing of intervention. Volumetric growth has been successfully used to assess growth of low-grade glioma; however, there is limited information on the volumetric growth rate (VGR) of meningiomas...

INTRODUCTION: Temporomandibular joint osteoarthritis (TMJ OA) is a degenerative disease characterized by deterioration of articular tissue with concomitant osseous changes in the condyle and/or articular eminence, joint positive for TMJ noise with jaw movement or function, crepitus detected on palpation on opening, closing, right/left lateral, or protrusive movement. Hyaluronic acid (HA) is a polysaccharide of the family of glycosaminoglycans. HA has been shown to improve and restore normal lubrication in joint, provide nutrition to the avascular articulating disc, and stabilize the joint...

Introduction: Cases of penetrating ocular trauma due to osseous material are limited, so reported incidents are valuable in determining outcomes and proper treatment courses. Case description: We report a case of an open globe injury of the left eye with an intraocular foreign body occurring after a firework exploded in the hand of a 22-year-old man. The patient presented with light perception vision in the injured eye with a full-thickness limbal laceration and dense hyphema obscuring fundoscopy. CT scan revealed a hyperdense foreign body juxtaposed to the lens...

A rapidly increasing number of mandibular condylar fractures and some complications related to injuries of temporomandibular elements make this study important. Intra-articular disorders lead to secondary pathological findings such as osteoarthritis, deforming osteoarthrosis, and temporomandibular joint ankylosis that limits mouth opening, mastication, swallowing, breathing, and decreased/lost working capacity or disability. Early diagnosis of intra-articular disorders can prevent from long-lasting functional complications caused by temporomandibular joint injuries...

BACKGROUND: Advancements in instrumentation and techniques have extended the scope of hip arthroscopic surgery to treat complex osseous deformities that were previously best addressed with an open approach. Global pincer-type femoroacetabular impingement is an example of an abnormality requiring osseous correction with a technically challenging access point. PURPOSE: To report on the patterns of clinical presentation and intra-articular derangements, radiological associations, and minimum 2-year outcomes after hip arthroscopic surgery in patients with a lateral center edge angle (LCEA) >40° and profunda acetabulae in comparison with matched controls with normal acetabular coverage...

While assessing skeletal injuries in human skeletal remains, forensic anthropologists are frequently presented with fractured, fragmented, or otherwise modified skeletal remains. The examination of evidence and the mechanisms of skeletal injuries often require that separate osseous elements be permanently or temporarily reassembled or reconstructed. If not dealt with properly, such reconstructions may impede accurate interpretation of the evidence. Nowadays, routine forensic examinations increasingly incorporate digital imaging technologies...

BACKGROUND: Commercially available flexible reamer and curved guide systems allow a certain degree of control over intra-articular tunnel orientation, therefore allows a wide range of intra-osseous femoral tunnel orientations, contrary to the femoral tunneling technique using a straight guide pin, which are determined by knee flexion angle. We sought to find the clinical relevance of intra-osseous femoral tunnel orientations in the respect of tunnel length. To evaluate the relationship between the tunnel axis angle in three orthogonal planes and tunnel length in the anteromedial (AM) and posterolateral (PL) femoral tunnels in patients who underwent anatomic double-bundle anterior cruciate ligament reconstruction (DB-ACLR) using the transportal (TP) technique with a 42(o) curved guide...

Mucoepidermoid carcinoma (MEC) is the malignant salivary gland neoplasm chiefly occurred in minor salivary gland. One of the rare variant of MEC is intra-osseous variant found in the jaws known as central mucoepidermoid carcinoma. Presently in this case report, we described a 28-year-old male diagnosed with central low grade mucoepidermoid carcinoma subsequently with the presence of asymptomatic swelling with a history of trauma. Clinically mimicking a cystic lesion and radiographically gives an idea of mixed radio-opaque radiolucent lesion which creates a confusion to render a final diagnosis...

We report a case series of aggressive fibromatosis of the forearm and discuss the differentiation criteria of overlapped intra- or extra-osseous origin of aggressive fibromatosis, surgical approach, and outcome. Ten cases of aggressive fibromatosis of the forearm were evaluated. When there was no involvement of vital adjacent structures, such as nerves, vessels, and tendons, en-bloc excision was performed for the removal of the soft-tissue mass. Bone involvement was observed in nine cases. Intercalary allograft was performed whenever one of the forearm bones was involved (six cases), while extensive curettage was used if both forearm bones were affected (three cases)...

The aim was to analyse the short-term and long-term therapeutic efficacy of dextrose prolotherapy for dislocation or subluxation (hypermobility) of the temporomandibular joint (TMJ). Sixty-one patients with symptomatic hypermobility of the TMJ were included in this single-arm prospective study, in which they were each given four sessions of intra-articular and pericapsular injections six weeks apart. Each injection comprised 10% dextrose/mepivacaine solution 3ml. Clinical outcomes including severity of pain on movement according to the numerical rating scale (NRS), maximal interincisal opening, clicking, and frequency of locking were measured before treatment (T1), during treatment (T2) (just before the third session of injections), at the short-term follow-up (T3) (three months after treatment), and at the long-term follow-up (T4) (1-4 years after treatment)...

Background Investigation of the venous system surrounding a tumor that is invading a dural sinus is of great use for guiding the surgical excision. Non-invasive imaging is often inadequate since enhancement of the tumor causes it to blend with the contrast of the venous vascular structures. Conventional two-dimensional angiography is also often insufficient. Objective The objective of this study was to report regarding the potential of three-dimensional digital subtracted computed tomography angiography (3D DS-CTA) as a technique to preoperatively explore these tumors...
