Scaphoid fractures accounts for approximately 15% of all fractures of hand and wrist. Proximal pole fractures represent 10–20% of scaphoid fractures. Non –operative treatment shows high incidence of non-union and avascular necrosis. Surgical intervention with bone graft is associated with better outcome. The aim of this study was to evaluate the radiological and functional outcome of management of proximal pole scaphoid non-union with internal fixation and bone grafting.

We included 35 patients with proximal pole scaphoid non-union (2008–2015). All patients underwent antegrade headless compression screw fixation and bone grafting at King's College Hospital, London (except one, who was fixed with Kirschner wire). 33 patients had bone graft from distal radius and two from iliac crest. Postoperatively patients were treated in plaster for 6–8 weeks, followed by splinting for 4–6 weeks and hand physiotherapy. All the patients were analysed at the final follow-up using DASH score and x-rays.

Mean age of the patients was 28 years (20–61) in 32 men and 3 women. We lost three patients (9%) to follow up. At a mean follow up of 16 weeks (12–18) twenty three patients (66%) achieved radiological union. All patients but three (91%) achieved good functional outcome at mean follow up of 14 weeks (10–16).

A good functional outcome can be achieved with surgical fixation and bone graft in proximal pole scaphoid fractures non-union. Pre-operative fragmentation of proximal pole dictates type of fixation (screw or k wire or no fixation). There was no difference in outcome whether graft was harvested from distal radius or iliac crest.

Evidence suggests that there 17% rise in cycling related injuries in the last year. The objective of the study is to analyze the pattern of injuries in cyclists who were treated as a MTC. This is a retrospective study performed at a Tertiary Trauma Centre in central London. All cyclists who were admitted as MTC to hospital between January 2011 and August 2013 were included. Overall there were 518 patients who were treated as vehicle- related Major Trauma Cases, out of which 118 (23%) were cyclists. Of the 118 cyclists, 98 (83%) were male and 20 (17%) female. The mean Injury Severity Score was 19.2 ±11.1 (mean/SD). There were 58 (49%) patients who required ITU support. Major proportion of patients (68 patients – 61%) sustained neurological injuries. There were 2 (1.7%) deaths, both due to neurological injuries. In comparison to other group of vehicles there is less number of bicycles on the roads. Our results show that the proportion of cyclists involved in road traffic incidents is higher (23%) than other vehicles. Our results show that large proportions (61%) of cyclists sustain neurological injuries, reinforcing the previous evidence that safe protective head gear is vital for cyclists.

The use of robots in orthopaedic surgery is an emerging field that is gaining momentum. It has the potential for significant improvements in surgical planning, accuracy of component implantation and patient safety. Advocates of robot-assisted systems describe better patient outcomes through improved pre-operative planning and enhanced execution of surgery. However, costs, limited availability, a lack of evidence regarding the efficiency and safety of such systems and an absence of long-term high-impact studies have restricted the widespread implementation of these systems. We have reviewed the literature on the efficacy, safety and current understanding of the use of robotics in orthopaedics.

Hypothesis

Recurrent shoulder dislocation is associated with bony defect of the glenoid rim, commonly seen along with bankart tear - a soft tissue injury of glenoid labrum. This cadaveric study compares the bone block effect of coracoid transfer using using two common techniques, Classical Latarjet technique and the Congruent-Arc Latarjet. We hypothesized that the force needed to dislocate the shoulder would be greater in Congruent Arc technique than the Classical Latarjet, because of increased contact surface area as a result of greater linear dimensions.
