BACKGROUND: Percutaneous endoscopic lumbar discectomy (PELD) is one of the less invasive treatments for lumbar disc herniation (LDH), and has 3 different operative approaches. This study focused on the posterolateral approach (PLA) and investigated the appropriate operative indication. METHODS: PLA was performed in 29 patients with foraminal and extraforaminal LDH. The height and width of the foramen, LDH type, and positional relationship between LDH and the foramen were radiologically evaluated...

This is a retrospective analysis of the clinical effects of transplant of mesenchymal stem cells (MSCs) derived from human umbilical cord-derived MSCs (hUC‑MSCs) for the treatment of osteonecrosis of the femoral head (ONFH). The biological characteristics of hUC-MSCs were assessed using flow cytometry. Nine eligible patients were enrolled in the study as they adhered to the Association Research Circulation Osseous (ARCO) classification of stage Ⅱ‑Ⅲa, and hUC‑MSCs were grafted by intra‑arterial infusion...

BACKGROUND: It is currently unknown whether bone erosion in gout occurs through an 'inside-out' mechanism due to direct intra-osseous crystal deposition or through an 'outside-in' mechanism from the surface of bone. The aim of this study was to examine the mechanism ('outside-in' vs. 'inside-out') of monosodium urate (MSU) crystal deposition in bone erosion in gout. Specifically, we used three-dimensional dual-energy computed tomography (DECT) to analyse the positional relationship between bone and MSU crystal deposition in tophaceous gout, and to determine whether intra-osseous crystal deposition occurs in the absence of erosion...

Arthroscopy of the ankle is used in the treatment and diagnosis of a spectrum of intra-articular pathology including soft tissue and osseous impingement, osteochondral lesions, arthrofibrosis, and synovitis. To help identify the correct pathology, imaging techniques are often used to aid the surgeon in diagnosing pathology and determining best treatment options. This article discusses the use of imaging in various ankle pathologies.

Myoepitheliomas (MEs) are uncommon tumours of the soft tissue with an intermediate biological behaviour and uncertain differentiation. Primary intra-osseous MEs are rare and occur predominantly in the axial and proximal appendicular skeleton in middle-aged patients. The morphological variation of the tumour cells and stromal metaplasia may cause considerable diagnostic confusion, especially when it occurs in an unusual location. A wide panel of immunohistochemical markers is required to exclude other histological mimics...

Acyanotic heart disease constitutes a significant majority of patient who may present with non-cardiac symptoms. Either they are detected incidentally or present with respiratory complaints. Equipped with knowledge of anatomy by echocardiography and radiographic methods described in previous part of this presentation, diagnosis may be confidently attempted. On plain radiography acyanotic congenital heart diseases have variable appearance depending upon severity of disease. Cardiac size, chamber enlargement and pulmonary vascular pattern are key elements...

BACKGROUND: Although rare, primary calvarial hemangioma is a known entity, surgical excision of which usually results in massive blood loss. Successful total excision of such a lesion remains a challenge, especially when these are in close vicinity of major venous sinuses. CASE DESCRIPTION: Authors describe a rare case of intra-osseous occipital cavernoma along with radiological findings in a 50-year-old male. En bloc resection of tumor was performed using a high-speed pneumatic drill and no recurrence was noted at 6 months of follow-up...

Osteonecrosis of the femoral head (ONFH) is a debilitating hip disorder, which often produces a permanent femoral head deformity and osteoarthritis. The local delivery of biological agents capable of stimulating bone healing offer potential new treatment options for patients with ONFH. Previous studies from our laboratory have shown that a local intraosseous infusion of bone morphogenic protein-2 (BMP-2) was effective in stimulating new bone formation in a piglet model of ischemic ONFH. However, infusion of BMP-2 solution was associated with unwanted dissemination of BMP-2 out of the femoral head and produced heterotopic ossification in the hip capsule...

PURPOSE: This study aims to study femoral tunnel lengths drilled with a flexible reamer and the distance to important lateral structures obtained by flexing the knee at various angles and by drilling the guide pins arthroscopically to resemble clinical practice. The purpose of this cadaveric study was twofold: 1. to determine whether femoral tunnel lengths of greater than 20 mm can be created with a flexible reamer system at 90 ° of knee flexion and 2. to determine whether the lateral structures of the knee are safe with this technique...

Appropriate graft length within the joint and inside the osseous tunnel is essential for achieving posterior stability and adequate anchorage strength. Because of the curving path and thickness of the graft in double-bundle posterior cruciate ligament (PCL) reconstruction, especially in double-bundle PCL augmentation (with remnant preservation), the actual intra-articular length of PCL grafts, which remains unknown, may be longer than previously published values. The main purpose of the current study is to measure the actual intra-articular graft length required in sandwich-style PCL reconstruction (remnant-preserving double-bundle PCL augmentation) and Zhao-style non-remnant-preserving double-bundle PCL reconstruction (semi-anatomic double-bundle PCL reconstruction using double-double tunnel with tibial medial and lateral arrangement)...

Myxomas are the most common non-invasive but life-threatening cardiac neoplasms due to obstruction of heart chambers and risk of embolism in a manner resembling thromboembolism as well. They can occasionally disseminate via their detached fragments into the bloodstream to seed and grow as secondary still benign tumors. In this study we evaluated morphological and clinical aspects of 14 ancient, degenerated left or right-sided cardiac atrial myxomas with expression of CD9 and CD63, which are found to contribute to platelet activation, aggregation and, as a result, intratumoral thrombosis or fragmentation...

Whole-body fluorine 18 fluorodeoxyglucose (FDG) positron-emission tomography (PET)/computed tomography (CT) is performed primarily for oncologic indications; however, FDG uptake is not specific for malignancy. Herein we focus on causes of increased FDG uptake in and around joints, as lesions in these locations are commonly benign. A combination of primary intra-articular processes and osseous processes that may occur near the joint space will be discussed. Causes of intra-articular and periarticular increased FDG activity can be broadly divided into infectious, inflammatory, degenerative, and benign neoplastic categories...

Low level laser has been documented in literature to promote wound healing by reducing postoperative inflammation, oedema and reduces pain. This case report demonstrates the safe and positive outcome of LLLT in conjunction with demineralised bone matrix of bovine origin in the surgical treatment of a periodontal infrabony defect. After surgical defect debridement, low level semiconductor diode laser (GaAlAr) was delivered for 5 minutes to the inner margins of flap in contact mode and the defect was irradiated with LLLT in a non-contact mode for 10 minutes...

BACKGROUND: Both unicameral bone cysts and intra-osseous lipoma of the calcaneus are rare entities which are mostly diagnosed due to unspecific heel pain, pathologic fracture or as an incidental finding. Minimally-invasive ossoscopy with endoscopic resection of the tumor followed by grafting can potentially minimize risks of open surgery and speed up convalescence. The objective of this study is to present a simple, safe and cost-effective surgical technique for endoscopic surgical treatment of benign osteolytic lesions of the calcaneus...

The posterior glenoid labrum has numerous surrounding structures and any of them can undergo derangement. It is prudent to consider the posterior glenoid labrum complex (PGLC) as a whole rather than simply the labral tissue in isolation when evaluating magnetic resonance imaging (MRI) of the shoulder. The PGLC contains the posterior capsulolabral junction, posterior capsule (posteroinferiorly , the posterior band of the inferior glenohumeral ligament), posterior chondro-osseous junction, posterior chondrolabral junction, posterior glenoid bone, posterior glenoid subchondral bone, posterior glenoid cartilage, posterior labrum, synovial fold (variably seen), and posterior glenoid periosteum (or periosteal sleeve)...

BACKGROUND: Indications for intra-osseous (IO) infusion are increasing in adults requiring administration of fluids and medications during initial resuscitation. However, this route is rarely used nowadays due to a lack of knowledge and training. We reviewed the current evidence for its use in adults requiring resuscitative procedures, the contraindications of the technique, and modalities for catheter implementation and skill acquisition. METHODS: A PubMed search for all articles published up to December 2015 was performed by using the terms "Intra-osseous" AND "Adult"...

UNLABELLED: This study aims to describe the pediatric physician-staffed EMS missions at a national level and to compare the pediatric and the adult EMS missions. Using a national database, we analyzed 254,812 interventions including 15,294 (6 %) pediatric emergencies. Less children than adults received an intravenous infusion (52.7 versus 77.1 %, p < 0.001), but the intra-osseous access was used more frequently in children (1.3 versus 0.8 %, p < 0.001). More children than adults benefited from a therapeutic immobilization (16...
