Introduction. Flexor tendon injuries are quite common injuries. They can result in persisting functional deficit if not repaired and appropriately rehabilitated. We look at flexor tendon injuries over a period of 1 year and re-audited three years later. Method. We audited all flexor tendon injuries that were treated at our institution and repeated the same audit three years after. We looked at various aspects of the injuries including the site injured, the zone of injury, other structures injured, the type of repair and material used as well as the rehabilitation regime. Results. The initial audit had 43 patients, 83% male, 55% unemployed with 85 tendon injuries. There were 35% zone 5 injuries with 34% repaired in <24hrs with modified Kessler core 3.0 prolene sutures and 6.0 prolene peripheral sutures. The rupture rate was 3% and the infection rate was 1%. A re-audited was done 3 years later, over the same time period, there were 69 patients, 83% male, 1% unemployed with 102 tendon injuries. There were 40% zone 2 injuries with 43% repaired with modified Kessler core 3.0 prolene sutures and 6.0 prolene peripheral sutures. Rupture rate was 9% and infection rate was 1% and 10% median nerve injury. All injuries were rehabilitated using the Belfast regime. Discussion and Conclusion. Flexor tendon injuries are frequently occurring injuries and require a careful and meticulous attention to detail, relative to repair, to achieve the most effective recovery. We found that over a three year period that the zone of injury in the cohort of patients in our region had changed, as well as the unemployment rate. Other parameters were generally similar. We conclude that treatment of flexor tendon injuries should undergo the audit cycle to ensure that best practice is achieved and maintained

Introduction. Many literatures regarding more specific tests to diagnose the supraspinatus tendon injuries and the best rehabilitation methods to strengthen the supraspinatus have been published. However, conflicting results have been reported. 2-deoxy-2-[18F] fluoro-D-glucose (FDG) positron emission tomography (PET) has been recently used to assess skeletal muscle activities in various fields. Purpose. To evaluate & compare the metabolic activities of deltoid & rotator cuff muscles after the full-can & empty-can exercises using PET-CT. Materials and Methods. Ten healthy volunteers (age 27–34/mean 29.8 ± 2.7) with no history of shoulder pain and diabetes mellitus participated in this study. After FDG injection, both arms were maintained in the position of empty can and full can for ten minutes respectively. PET-CT was performed at forty minutes after the injection. The maximum standardized uptake value (SUV) was measured in the anterior, middle and posterior deltoid, supraspinatus, subacapularis and infraspinauts on the entire axial images. Results. The middle deltoid and subscapularis showed significantly greater activity during the empty-can exercise than during the full-can exercise (P=.006 and P=.003 respectively). The muscular activity of the supraspinatus also increased during the empty-can exercise than during the full-can exercise, although no statistical difference existed between two exercises. Six cases of eight cases who had increased activity of the subscapularis had increased activity in superior one half of the subscapularis than in lower one half of it, although there is no significant difference between two portions. Conclusion. The Empty-can exercise requires more strength of the middle deltoid, subscapularis and supraspinatus to keep the arm in internal rotation. The increased activity of the middle deltoid and subscapularis muscles after the empty-can exercise can make the empty-can test less specific to the supraspinatus muscle. The empty-can test can induce pain and weakness due to the subscapularis pathology. The full-can test can be used to test the function of the supraspinatus with the least amount of surrounding middle deltoid and subacapularis muslce activity

Aims

It is imperative to understand the risks of operating on urgent cases during the COVID-19 (SARS-Cov-2 virus) pandemic for clinical decision-making and medical resource planning. The primary aim was to determine the mortality risk and associated variables when operating on urgent cases during the COVID-19 pandemic. The secondary objective was to assess differences in the outcome of patients treated between sites treating COVID-19 and a separate surgical site.

Introduction. Anterior Cruciate ligament reconstruction is a common operation in orthopaedics surgery. A common complication of whilst havesting the hamstring tendon is injury to the infra-patellar branch of the saphenous nerve (IPBSN), resulting in altered sensation to the anterior and lateral aspects of the knee and leg. Aim. The aim of this study was to further understand the course of this nerve in relation to surgical approach to anterior cruciate ligament reconstruction. Material and method. The nerve was traced and dissected in 25 knees from 14 different cadavers. Four paths of IPBSN in relation to the Sartorius muscle were identified: (1) a posterior path which ran round the inferior posterior border of the muscle, (2) a transmuscular path that penetrated through the muscle, (3) an anterior path that ran from the anterior border of the muscle and (4) posterior patellar path that ran round the posterior of the muscle at the same level as the patellar. Dissections were carried out with further 14 knees in a standard manner using both type of incision techniques, vertical incision or horizontal, in ten pair of knees. Using a tendon stripper, the hamstrings tendon were harvested in a standard fashion in different angles of the knee ie full extension and flexion at 90 degrees. Results. Of these paths the posterior was the most common featuring in 57% of specimens and the nerve was at higher risk of being injured due to the proximity of that pathway and the gracilis and semintendinosus muscle tendons. Horizontal incision has a higher chance of damage to the saphenous nerve and the infra-patellar branch. The saphenous nerve was injured on every occasion by this incision. Vertical incision, 1.5cm from the midline, avoided the infra-patellar branch and the saphenous nerve. Harvesting of the tendon in full extension was difficult, and it made the incision sites both horizontal and vertical at greater risk injuring the tendons. When the knee was flexed at 90 degrees these problems were overcome. Conclusions. A vertical incision with a flexed knee gave the best method to harvest the tendon with minimal risk to damaging the infra-patellar branch and the saphenous nerve when using the tendon stripper

Aims

The purpose of this study was to identify factors associated with limitations in function, measured by patient-reported outcome measures (PROMs), six to nine months after a proximal humeral fracture, from a range of demographic, injury, psychological, and social variables measured within a week and two to four weeks after injury.

Injuries to the limb are the most frequent cause of permanent disability following combat wounds. We reviewed the medical records of 450 soldiers to determine the type of upper limb nerve injuries sustained, the rate of remaining motor and sensory deficits at final follow-up, and the type of Army disability ratings granted. Of 189 soldiers with an injury of the upper limb, 70 had nerve-related trauma. There were 62 men and eight women with a mean age of 25 years (18 to 49). Disabilities due to nerve injuries were associated with loss of function, neuropathic pain or both. The mean nerve-related disability was 26% (0% to 70%), accounting for over one-half of this cohort’s cumulative disability. Patients injured in an explosion had higher disability ratings than those injured by gunshot. The ulnar nerve was most commonly injured, but most disability was associated with radial nerve trauma. In terms of the final outcome, at military discharge 59 subjects (84%) experienced persistent weakness, 48 (69%) had a persistent sensory deficit and 17 (24%) experienced chronic pain from scar-related or neuropathic pain. Nerve injury was the cause of frequent and substantial disability in our cohort of wounded soldiers.

This randomised study compared outcomes in patients with displaced fractures of the clavicle treated by open reduction and fixation by a reconstruction plate which was placed either superiorly or three-dimensionally. Between 2003 and 2006, 133 consecutive patients with a mean age of 44.2 years (18 to 60) with displaced midshaft fractures of the clavicle were allocated randomly to a three-dimensional (3D) (67 patients) or superior group (66). Outcome measures included the peri-operative outcome index, delayed union, revision surgery and symptoms beyond 16 weeks. CT was used to reconstruct an image of each affected clavicle and Photoshop 7.0 software employed to calculate the percentage of the clavicular cortical area in the sagittal plane. The patients were reviewed clinically and radiographically at four and 12 months after the operation. The superior plate group had a higher rate of delayed union and had more symptomatic patients than the 3D group (p < 0.05). The percentage comparisons of cortical bone area showed that cortical bone in the superior distal segment is thicker than in the inferior segment, it is also thicker in the anterior mid-section than in the posterior (p < 0.05).

If fixation of midshaft fractures of the clavicle with a plate is indicated, a 3D reconstruction plate is better than one placed superiorly, because it is consistent with the stress distribution and shape of the clavicle.

A total of 118 consecutive patients with a fracture of the distal radius were treated with a volar locking plate; 50 patients had no ulnar styloid fracture, 41 had a basal ulnar styloid fracture, and 27 had a fracture of the tip of the ulnar styloid. There were no significant differences in radiological and clinical results among the three groups. The outcome was good and was independent of the presence of a fracture of the ulnar styloid. A total of five patients (4.2%) had persistent ulnar-sided wrist pain at final follow-up. Nonunion of the ulnar styloid fracture did not necessarily lead to ulnar wrist pain. Patients with persistent ulnar pain had a higher mean initial ulnar variance and increased post-operative loss of ulnar variance.

The presence of an associated ulnar styloid fracture of the ulnar styloid does not adversely affect the outcome in patients with a fracture of the distal radius treated by volar plating.

Stable fractures of the ankle can be successfully treated non-operatively by a below-knee plaster cast. In some centres, patients with this injury are routinely administered low-molecular-weight heparin, to reduce the risk of deep-vein thrombosis (DVT). We have assessed the incidence of DVT in 100 patients in the absence of any thromboprophylaxis. A colour Doppler duplex ultrasound scan was done at the time of the removal of the cast.

Five patients did develop DVT, though none had clinical signs suggestive of it. One case involved the femoral and another the popliteal vein. No patient developed pulmonary embolism. As the incidence of DVT after ankle fractures is low, we do not recommend routine thromboprophylaxis.

Four men who presented with chronic dislocation of the radial head and nonunion or malunion of the ulna were reviewed after open reduction of the radial head and internal fixation of the ulna in attempted overcorrection. Their mean age was 37 years (28 to 46) and the mean interval between injury and reconstruction was nine months (4 to 18).

The mean follow-up was 24 months (15 to 36). One patient who had undergone secondary excision of the radial head was also followed up for comparison.

The three patients who had followed the treatment protocol had nearly normal flexion, extension and supination and only very occasional pain. All had considerable loss of pronation which did not affect patient satisfaction.

Preservation of the radial head in chronic adult Monteggia fractures appears to be a promising mode of treatment.
