There is currently no commercially available and clinically successful treatment for scapholunate interosseous ligament rupture, the latter leading to the development of hand-wrist osteoarthritis. We have created a novel biodegradable implant which fixed the dissociated scaphoid and lunate bones and encourages regeneration of the ruptured native ligament. To determine if scaphoid and lunate kinematics in cadaveric specimens were maintained during robotic manipulation, when comparing the native
Introduction and Objective. Scapholunate instability is the most common cause of carpal instability. When this instability is left untreated, the mechanical relationship between the carpal bones is permanently disrupted, resulting in progressive degenerative changes in the radiocarpal and midcarpal joints. Different tenodesis methods are used in the treatment of acute or early chronic reducible scapholunate instability, where arthritis has not developed yet and the scapholunate ligament cannot be repaired. Although it has been reported that pain is reduced in the early follow up in clinical studies with these methods, radiological results differ between studies. The deterioration of these radiological parameters is associated with
Radial head fractures are among the most common fractures around the elbow. Radial head arthroplasty is one of the surgical treatment options after complex radial head fractures. This surgery is usually done under general anaesthesia. However, there is a recent anaesthetic technique - wide awake local anaesthesia no tourniquet (WALANT) - that has proven useful in different surgical settings, such as in distal radius or olecranon fractures. It allows a good haemostatic control without the use of a tourniquet and allows the patient to actively collaborate during the surgical procedure. Furthermore, there are no side effects or complications caused by the general anaesthesia and there's an earlier patient discharge. The authors present the case of a seventy-six-year-old woman who presented to the emergency department after a fall from standing height with direct trauma to the left elbow. The radiological examination revealed a complete intra-articular comminuted fracture of the radial head (Mason III). Clinical management: The patient was submitted to surgery with radial head arthroplasty, using WALANT. The surgery was successfully completed without pain. There were no intra or immediate post-operative complications and the patient was discharged on the same day. Six weeks after surgery, the patient had almost full range of motion and was very pleased with the functional outcome, with no limitations on her activities of daily living. The use of WALANT has been expanded beyond the hand and
Nerve transfer is an emerging treatment to restore upper limb function in people with tetraplegia. The objective of this study is to examine if a flexible collage sheet (FCS) can act as epineurial-like substitute to promote nerve repair in nerve transfer. A preclinical study using FCS was conducted in a rat model of sciatic nerve transection. A prospective case series study of nerve transfer was conducted in patients with C5-C8 tetraplegia who received nerve transfer to restore upper limb function. Motor function in the upper limb was assessed pre-treatment, and at 6-,12-, and 24-months post-treatment. Macroscopic assessment in preclinical model showed nerve healing by FCS without encapsulation or adhesions. Microscopic examination revealed that a new, vascularised epineurium-like layer was observed at the FCS treatment sites, with no evidence of inflammatory reaction or nerve compression. Treatment with FCS resulted in well-organised nerve fibres with dense neurofilaments distal to the coaptation site. Axon counts performed proximal and distal to the coaptation site showed that 97% of proximal axon count of myelinated axons regenerated across the coaptation site after treatment with CND. In the proof of concept clinical study 17 nerve transfers were performed in five patients. Nerve transfers included procedures to restore triceps function (N=4),
This study aims to compare the outcomes of Volar locking plating (VLP) versus percutaneous Kirschner wires (K-wire) fixation for surgical management of distal radius fractures. We systematically searched multiple databases, including MEDLINE for randomized controlled trials (RCTs) comparing outcomes of VLP fixation and K-wire for treatment of distal radius fracture in adults. The methodological quality of each study was assessed by the Cochrane Risk of Bias tool. Patient-reported outcomes, functional outcomes, and complications at 1 year follow up were evaluated. Meta-analysis was performed using random-effects models and results presented as risk ratios (RRs) or mean differences (MDs) with 95% confidence interval (CI). 13 RCTs with 1336 participants met the inclusion criteria. Disabilities of the Arm, Shoulder and Hand (DASH) scores were significantly better for VLP fixation (MD= 2.15; 95% CI, 0.56-3.74; P = 0.01; I2=23%). No significant difference between the two procedures for grip strength measured in kilograms (MD= −3.84; 95% CI,-8.42-0.74; P = 0.10; I2=52%) and Patient-Rated
X-Linked Hypophosphataemia (XLH) is a rare, progressive, hereditary phosphate-wasting disorder characterised by excessive activity of fibroblast growth factor 23. The International XLH Registry was established to provide information on the natural history of XLH and impact of treatment on patient outcomes. The cross-sectional orthopaedic data presented are from the first interim analysis. The XLH Registry (NCT03193476) was initiated in August 2017, aims to recruit 1,200 children and adults with XLH, and will run for 10 years. At the time of analysis (Last Patient In: 30/11/2020; Database Lock: 29/03/2021) 579 subjects diagnosed with XLH were enrolled from 81 hospital sites in 16 countries (360 (62.2%) children, 217 (37.5%) adults, and 2 subjects of unknown age). Of subjects with retrospective clinical data available, skeletal deficits were the most frequently self-reported clinical problems for children (223/239, 93.3%) and adults (79/110, 71.8%). Retrospective fracture data were available for 183 subjects (72 children, 111 adults); 50 had a fracture (9 children, 41 adults). In children, fractures tended to occur in tibia/fibula and/or
In current practice in the UK there are three main approaches to investigating suspected scaphoid fractures not seen on initial plain film x-rays. Early MRI of all cases. Review all cases in clinic at two weeks with repeat x-rays. Hybrid model. Virtual Fracture Clinic (VFC) triage to reduce those who are seen in clinic at two weeks by:. ∘. Organising early MRI for those with high-risk presentation. ∘. Discharging those with an alternative more likely diagnosis. Our unit uses the VFC model. We aimed to evaluate its efficiency, safety, clinical outcomes and economic viability. All patients attending the emergency department with either a confirmed or suspected scaphoid fracture between March and December 2020 were included (n=305). Of these 297 were referred to the VFC: 33 had a confirmed fracture on x-ray and 264 had a suspected fracture. Of the suspected fractures reviewed in VFC 14% had an MRI organised directly owing to a high-risk presentation, 79% were brought for fracture clinic review and 17% discharged with an alternative diagnosis such as osteoarthritis. Of those subsequently reviewed in fracture clinic at two weeks: 9% were treated as scaphoid fractures (based on clinical suspicion and repeat x-rays), 17% had MRI or CT imaging organised, 5% did not attend and 69% were discharged. Overall, 17% of cases initially triaged, had further imaging – 41 MRIs and 5 CTs. MRI detected: 5% scaphoid fracture, 17% other fracture, 24% bone contusion, complete ligament tear 10%, partial ligament tear 39% and normal study 10%. The results of MRI minimally affected management. 3 patients were taken out of plaster early, 1 patient was immobilized who was not previously and no patients underwent operative management. In the following 12-month period one patient re-presented with a hand or
Abstract. Objectives. The aim of this study was to investigate whether mechanical loading induced by physical activity can reduce risk of sarcopenia in middle-aged adults. Methods. This was a longitudinal study based on a subset of UK Biobank data consisting of 1,918 participants (902 men and 1,016 women, mean age 56 years) who had no sarcopenia at baseline (assessed between 2006 and 2010). The participants were assessed again after 6 years at follow-up, and were categorized into no sarcopenia, probable sarcopenia, or sarcopenia according to the definition and algorithm developed in 2018 by European Working Group on Sarcopenia in Older People (EWGSOP). Physical activity was assessed at a time between baseline and follow-up using 7-day acceleration data obtained from
Distal radius fractures (DRF) are very common injuries. National recommendations (British Orthopaedic Association, National Institute for Health and Care Excellence (NICE)) exist in the UK to guide the management of these injuries. These guidelines provide recommendations about several aspects of care including which type of injuries to treat non-operatively and surgically, timing of surgery and routine follow-up. In particular, current recommendations include considering immobilizing patients for 4 weeks in plaster for those managed conservatively, and operating on fractures within 72 hours for intra-articular injuries and 7 days for extra-articular fractures. With increased demands for services and an ageing population, prompt surgery for those presenting with distal radius fractures is not always possible. A key factor is the need for prompt surgery for hip fracture patients. This study is an audit of the current standard of care at a busy level 2 trauma unit against national guidelines for the management of DRFs. This retrospective audit includes all patients presenting to our emergency department from June to September 2018. Patients over 18 years of age with a diagnosis of a closed distal radius fracture and follow-up in our department were included in the study. Those with open fractures were excluded. Data was retrieved from clinical coding, electronic patient records, and IMPAX Client (Picture archiving and communication system). The following data was collected on patients treated conservatively and those managed surgically:- (1)Time to surgery for surgical management; (2)Period of immobilization for both conservative and operative groups. 45 patients (13 male, 32 female) with 49 distal radius fractures (2 patients had bilateral injuries) were included. Patients had mean age 63 years (range 19 to 92 years) 30
The treatment of scapholunate (SL) ligament injuries is addressed by surgical procedures to stabilize the carpal joint. Open techniques include bone-ligament-bone transfers, tenodesis, partial fusions and carpectomies. Innovative procedures using

Summary. When a TFCC tear is diagnosed, practitioners should maintain a high level of suspicion for the presence of a concomitant SL or LT ligament tear. Introduction. Disruption of the scapholunate (SL) or lunotriquetral (LT) ligament leads to dorsal and volar intercalated segment instability, respectively, while triangular fibrocartilage complex (TFCC) tears result in distal radioulnar joint (DRUJ) instability. Viegas et al. (1993) demonstrated that 56% of grossly visualised cadaveric
Introduction and Objective. Individuals with type 2 diabetes (T2D) have a 3-fold increased risk of bone fracture compared to non-diabetics, with the majority of fractures occurring in the hip, vertebrae and
Summary. Practitioners should maintain a high suspicion of concurrent carpal fractures in patients who present with a distal radius fracture after a fall onto an outstretched hand, particularly if forearm rotation is involved. Introduction. Simultaneous scaphoid and distal radius fractures, and the importance of their identification, have been previously described in multiple reports. However, few studies have investigated the incidence of carpal fractures, in general, occurring concurrently with distal radius fractures after a common mechanism of
