Aims. The increase in prescription opioid misuse and dependence is now a public health crisis in the UK. It is recognized as a whole-person problem that involves both the medical and the psychosocial needs of patients. Analyzing aspects of pathophysiology, emotional health, and social wellbeing associated with persistent opioid use after injury may inform safe and effective alleviation of pain while minimizing risk of misuse or dependence. Our objectives were to investigate patient factors associated with opioid use two to four weeks and six to nine months after an

In bone and joint infections, several materials can be used for local antibiotic elution at site of infection. Polymethylmethacrylate (PMMA) cement is often used. Recently the use of antibiotic impregnated dissolvable synthetic pure calcium sulphate beads [Stimulan R]1 has been used as an alternative, due to several perceived advantages. We present our experience of using Calcium sulphate beads in infections involving the

Fractures to the distal radius are costly and debilitating injuries. While it is generally accepted that the leading cause of these injuries is a fall onto an outstretched arm, the mechanics of the injury are less well understood. The main limitations of past research are the use of unrealistic loading rates or uncontrolled loading protocols. Therefore, the purpose of this research was to examine the mechanical response of the distal radius pre-fracture and at fracture, under dynamic loads indicative of a forward fall. Eight cadaveric radius specimens were cleaned of all soft tissues and potted at a 75o angle (representative of the angle between the volar radius and the ground) up to the distal third of the radius. A custom designed pneumatic impact system was used to apply impulsive impacts to the specimen at increasing energy levels until failure occurred. The intra-articular surface of the radius rested against a model scaphoid and lunate made from high density polyethylene (Sawbones) attached to a 5 degree of freedom load cell that in turn was attached to an impact plate. The position of the carpals within the intra-articular surface simulated 45o of wrist extension. Following failure (defined as the specimen being fractured into at least 2 distinct pieces), the specimens were removed from the testing apparatus and the location, type, pattern and severity of injury was noted and classified using the Frykman and Melone classification systems. Energy input and force variables were also collected at failure.Purpose
Method
20 cases of bone defect have been treated by the induced membrane technique avoiding allograft, microsurgery and amputation 9 cases of long bone defect (humerus and forearm) and 11 cases of bone defect at the hand have been included in this multicentre prospective study (3 centers). The aetiology in 11 cases was trauma, 7 cases were septic nonunions and 2 cases followed tumors. In the hand the bone loss was at least one phalanx, and for long bones the mean defect was 5 cm (3–11). All cases were treated by the induced membrane technique which consists in stable fixation, flap if necessary and in filling the void created by the bone defect by a cement spacer (PMMA). This technique needs a second stage procedure at the 2nd month where the cement is removed and the void is filled by cancellous bone. The key point of this induced membrane technique is to respect the foreign body membrane which appeared around the cement spacer and which creates a biologic chamber for the second procedure. Bone union was evaluated prospectively in each case by a surgeon not involved in the treatment, by X-ray and CT scan. Failure was defined as a nonunion at 1 year, or an uncontrolled sepsis at 1 month.Introduction:

To describe the incidence, nature, and risk factors associated with upper limb injuries in athletes participating in the London 2012 Paralympic Games. This study formed a component of the large prospective cohort study conducted over the 14-day period of the London 2012 Paralympic Games, coordinated through the IPC Medical Committee. Daily injury data were collected by team physicians in 3 329 athletes (46 606 athlete days) participating in the study, and 258 upper limb injuries were recorded. The incidence proportion (IP=number of injuries per 100 athletes), and incidence (number of injuries per 1000 athlete days) of upper limb injuries was calculated.Purpose of the study:

Novel immersive virtual reality (IVR) technologies are revolutionizing medical education. Virtual anatomy education using head-mounted displays allows users to interact with virtual anatomical objects, move within the virtual rooms, and interact with other virtual users. While IVR has been shown to be more effective than textbook learning and 3D computer models presented in 2D screens, the effectiveness of IVR compared to cadaveric models in anatomy education is currently unknown. In this study, we aim to compare the effectiveness of IVR with direct cadaveric bone models in teaching upper and lower limb anatomy for first-year medical students. A randomized, double-blind crossover non-inferiority trial was conducted. Participants were first-year medical students from a single University. Exclusion criteria included students who undertook prior undergraduate or graduate degrees in anatomy. In the first stage of the study, students were randomized in a 1:1 ratio to IVR or cadaveric bone groups studying

The ability to calculate quality-adjusted life-years (QALYs) for degenerative cervical myelopathy (DCM) would enhance treatment decision making and facilitate economic analysis. QALYs are calculated using utilities, or health-related quality-of-life (HRQoL) weights. An instrument designed for cervical myelopathy disease would increase the sensitivity and specificity of HRQoL assessments. The objective of this study is to develop a multi-attribute utility function for the modified Japanese Orthopedic Association (mJOA) Score. We recruited a sample of 760 adults from a market research panel. Using an online discrete choice experiment (DCE), participants rated 8 choice sets based on mJOA health states. A multi-attribute utility function was estimated using a mixed multinomial-logit regression model (MIXL). The sample was partitioned into a training set used for model fitting and validation set used for model evaluation. The regression model demonstrated good predictive performance on the validation set with an AUC of 0.81 (95% CI: 0.80-0.82)). The regression model was used to develop a utility scoring rubric for the mJOA. Regression results revealed that participants did not regard all mJOA domains as equally important. The rank order of importance was (in decreasing order): lower extremity motor function,
