Radiation exposure with use of intraoperative fluoroscopy is a potential orthopedic occupational risk factor. The purpose of this study was to perform a prospective comparison of hand versus eye radiation exposure associated with mini-C-arm utilization and to test the hypothesis that routine mini-C-arm does not yield hand or eye dosages exceeding current recommended levels. Over a 12-month period, hand and eye radiation exposure was prospectively measured in a single board-certified hand surgeon using mini-C-arm fluoroscopy...

A 3-month-old male umbrella cockatoo (Cacatua alba) was presented because of acute non-weight-bearing lameness of the right leg. Marked soft tissue swelling was present around the femorotibiotarsal (stifle) joint, and the radiographic diagnosis was right medial femorotibiotarsal subluxation. Surgical management was elected, and the stifle joint was approached via a lateral parapatellar incision. Joint exploration revealed damage to the lateral meniscus, tendon of origin of the cranial tibial muscle, and cranial cruciate ligament...

Patient safety has become a central and measurable key factor in the routine daily medical practice. The human factor plays a decisive role in safety culture and has moved into focus regarding the reduction of treatment errors and undesired critical incidents. Nonetheless, the systematic training in communication and interpersonal competences has so far only played a minor role. The German Society of Orthopaedics and Trauma (DGOU) in cooperation with the Lufthansa Aviation Training initiated a course system for interpersonal competence...

INTRODUCTION: Despite the use of modern antibiotics as well as complex perioperative, intraoperative and postoperative prophylactic measures, the rate of surgical site infections (SSI) could not be significantly reduced. The introduction of biocompatible antiseptic drugs with a high microbiocidal effect provided a successful alternative for infection prevention and therapy, particularly in a time of increasing occurrence of multi-drug resistant pathogens. Hence, questions about the risk-benefit ratio of antiseptic wound irrigation solutions, the prophylactic use of wound irrigation solutions for the reduction of SSI and the effect of negative pressure wound therapy combined with instillation (NPWTi) need to be answered...

Knowledge of the muscle, ligament and joint forces is important when planning orthopedic surgeries. Since these quantities cannot be measured in vivo under normal circumstances, the best alternative is to estimate them using musculoskeletal models. These models typically assume idealized joints, which are sufficient for general investigations but insufficient if the joint in focus is far from an idealized joint. The purpose of this study was to provide the mathematical details of a novel musculoskeletal modelling approach, called Force-dependent Kinematics (FDK), capable of simultaneously computing muscle, ligament and joint forces as well as internal joint displacements governed by contact surfaces and ligament structures...

BACKGROUND: Although arthroscopic surgical treatment of the first metatarsophalangeal (MTP) joint involves painful sesamoid excision, synovectomy, debridement, and partial cheilectomy, no gold standard treatment technique has been defined in the literature for hallux rigidus and focal osteochondral lesions. This study aimed to assess the arthroscopic treatment for early-grade focal osteochondral lesions of the first MTP joint and to determine the impact of arthroscopic microhole drill surgery on foot function and activities of daily living in a group of patients who failed conservative treatment...

INTRODUCTION: Foot deformities are frequent complications in Charcot-Marie-Tooth disease (CMT) patients, often requiring orthopedic surgery. However there are no prospective randomized studies on surgical management, and there is variation in the approache between centers in the same country and between different countries. METHODS: We assessed the frequency of foot deformities and surgery among patients recruited to the Inherited Neuropathies Consortium (INC). We also designed a survey addressed to orthopedic surgeons at INC centers to determine whether surgical approaches to orthopedic complications in CMT are variable...

Bone graft procedures, in particular maxillofacial repair, account for half of the orthopedic procedures done in the US each year. Infection is a major issue in surgery, and should be of primary concern when engineering biomaterials. Silver is of renewed importance today, as it has the ability to potentiate antibiotics against resistant bacterial strains. In order to reduce long term infection risks, it is necessary for the scaffold to maintain a silver ion release for the length of the healing process. In this study, silver doped porous β-tricalcium phosphate (β-TCP) scaffolds were engineered using liquid porogen based method with the goal of meeting these requirements...

Hypotensive anesthesia is utilized to reduce bleeding during orthopedic surgery. One of the various drugs that have been used to reduce blood pressure is remifentanil. This study was an attempt to compare the effect of remifentanil with that of electroacupuncture (EA) at DU20 on reducing blood pressure. In this randomized controlled clinical trial, 54 patients undergoing lumbar laminectomy were allocated to two groups. Hypotensive anesthesia was performed through infusion of remifentanil 100 μg/kg/min for the control group, and EA at DU20 acupoint with a frequency of 2-10 Hz and intensity of 1-5 mA for the intervention group...

BACKGROUND: Economic downturn can have a wide range of effects on medicine at both individual and national levels. We aim to describe these effects in relation to surgical volume to guide future planning for physician specialization, patient expectations in the face of economic crises, or estimating healthcare expenditure. We hypothesized that because of high out-of-pocket costs, cosmetic procedure volumes would be most affected by economic decline. METHODS: A systematic review was conducted using MEDLINE, Embase, and ABI/INFORMS...
