The COVID-19 pandemic presented a significant impact on orthopaedic surgical operating. This multi-centre study aimed to ascertain what factors contributed to delays to theatre in patients with shoulder and elbow trauma.

A retrospective cohort study of 621 upper limb (shoulder and elbow) trauma patients between 16/03/2020 and 16/09/2021 (18-months) was extracted from trauma lists in NHS Tayside, Highland and Grampian and Picture Archiving and Communication Systems (PACS).

Median patient age =51 years (range 2-98), 298 (48%) were male and 323 (52%) female. The commonest operation was olecranon open reduction internal fixation (ORIF) 106/621 cases (17.1%), followed by distal humerus ORIF − 63/621 (10.1%). Median time to surgery was 2 days (range 0-263). 281/621 (45.2%) of patients underwent surgical intervention within 0-1 days and 555/621 patients (89.9%) had an operation within 14 days of sustaining their injury. 66/621 (10.6%) patients waited >14 days for surgery. There were 325/621 (52.3%) patients with documented evidence of delay to surgery; of these 55.6% (181/325) were due to amendable causes. 66/325 (20.3%) of these patients suffered complications; the most common being post-operative stiffness in 48.6% of cases (n=32/66).

To our knowledge, this is the first study to specifically explore effect of COVID-19 pandemic on upper limb trauma patients. We suggest delays to theatre may have contributed to higher rates of post-operative stiffness and require more physiotherapy during the rehabilitation phase. In future pandemic planning, we propose dedicated upper-limb trauma lists to prevent delays to theatre and optimise patients’ post-operative outcomes.

Abstract

Newer irreversible oral anticoagulants such as rivaroxaban, a direct factor 10a inhibitor, are increasingly employed to prevent thromboembolic events in atrial fibrillation (AF) patients, and to manage venous thromboembolism (VTE). Unlike warfarin, these agents require no monitoring and involve infrequent dose adjustment. We report the case of a patient treated with rivaroxaban for AF. Patient presented with unprovoked sudden onset right shoulder pain which clinically resembled shoulder haemarthrosis.

A single case was anonymised and retrospectively reviewed through examination of clinical and radiographic data.

A 70 year old female with known AF presented to Accident and Emergency with sudden onset of right shoulder pain and limited movement, which developed over one hour. The pain was constant, localised to the shoulder and without trauma. Past medical history included severe aortic regurgitation and associated thoracic aortic aneurysm, heart failure, atrial fibrillation and hypertension. Observations were normal upon admission with no haemodynamic compromise or pyrexia. Examining the right shoulder demonstrated distension of shoulder joint capsule, tenderness and a reduced range of movement. Temperature and neurovascular status in the right arm were normal. Investigations upon admission included an INR of 1.2. An anteroposterior right shoulder radiograph showed no evidence of fracture. Patient was managed conservatively with simple oral analgesia. Importantly, rivaroxaban was withheld for 5 days and symptoms resolved. Warfarin therapy was subsequently commenced instead as treatment for AF. Patient was discharged one week later and seen in clinic two weeks post-discharge. A full recovery occurred and with a full range of movement in the right shoulder.

In the UK, current National Institute for Health and Care Excellence (NICE) guidelines recommend the use of factor 10a inhibitors, for prevention of stroke in AF patients, and following elective total hip and knee replacement operations to prevent VTE. In turn, rivaroxaban is increasingly prescribed as first line therapy. Whereas warfarin has a documented association with haemarthrosis, there is no primary literature evaluating the incidence of factor 10a therapy associated haemarthrosis. In our case, the unprovoked shoulder haemarthrosis resolved following rivaroxaban cessation. In comparison with warfarin, rivaroxaban is irreversible. With warfarin and a high INR, vitamin K can be used to reverse the anticoagulation. There is no equivalent for rivaroxaban. We suggest further studies into incidence of haemarthrosis associated with oral anticoagulant therapy be undertaken, and treating physicians be aware of such complication.

Lateral Epicondylitis is a common condition caused by angiofibroblastic hyperplasia of the tendinous insertion. Its treatment is varied and includes rest, physiotherapy, corticosteroid injection and surgical release. Of late, the role of Platelet Rich Plasma (PRP) injections have been explored, with positive results.

We prospectively assessed the outcomes of lateral epicondylitis treated with PRP injections and compared the outcomes of ultrasound guided and ‘blind’ injection.

This was a single centre prospective cohort study. Patient were assessed with the Disabilities of the Arm, Shoulder and Hand (DASH) Score. PRP was injected into and around the common extensor origin either with or without ultrasound guidance. The primary outcome measure was DASH score at 3 months.

45 (23F:22M) patients were recruited. The mean age was 50 years (range 35 to 79). The mean duration of follow-up was 106 days. The average pre-injection DASH score for both groups combined was 45.5 (11.7–87.5). The mean DASH score at 3 months follow-up was 27.7. The ultrasound guided injection group had a mean improvement in DASH score from 45.5 to 31.2. The “blind” injection group had a mean improvement in DASH from 44.4 to 27.7. No complications were noted. There was no statistically significant difference in improvement in DASH score between the two groups.

Our study provides further evidence to support of the use of PRP injections in the treatment of epicondylitis of the elbow. Interestingly, however, we found that the use of Ultrasound guidance does not appear to improve patient outcomes.

The objective was to compare vastus lateralis muscle splitting verses muscle sparing surgical approach to proximal femur for fixation of intertrochanteric fracture.

Of the 16 patients in this prospective randomised double blind study 8 were randomised to vastus lateralis muscle splitting and rest to muscle sparing group. Main outcome measurement was assessment of status of vastus lateralis muscle at 2 and 6 weeks using nerve conduction study. Preoperative demographics were identical for both the groups.

There was no statistically significant difference between the groups with regards to velocity, latency, and amplitude. The postoperative haemoglobin drop, heamatocrit, position of the dynamic hip screw and mobility status were identical.

Both clinical and neurophysiological outcome suggest that damage done to vastus lateralis either by splitting or elevating appears to be identical.

Introduction: Current Literature is sparse with respect to the optimum surgical approach for fixation of a fractured neck of Femur. A cadaveric study has been performed to determine the pattern of innervation of the Vastus Lateralis muscle. Results indicate that a muscle splitting technique may cause more nerve damage than a muscle reflection technique. The purpose of this study was to determine the clinical and neurophysiological effects of two different surgical approaches to the proximal femur.

Methods: Patients were randomised to receive either a Vastus splitting approach or a Vastus reflecting approach to the fractured femoral neck. The contralateral leg was used as the control for neurophysiological investigation. Needle electromyography was performed on both the operated and unoperated limbs within 2 weeks of surgery.

Results: 25 patients were included in the study randomisation. A total of 17 patients completed neurophysiological investigation, 8 in muscle reflection and 9 in muscle splitting groups. There was a significant reduction in femoral nerve conduction velocity compared to the unoperated control side in the muscle split group. This was also the case for amplitude of response measured in the Vastus muscle. The muscle reflection group showed no significant differences in these parameters compared to the unoperated side.

Conclusion: On the basis of the results of this study we recommend a Vastus Lateralis reflecting approach for proximal Femoral fracture fixation. The functional outcome of a muscle splitting approach remains unclear but could be investigated as part of a larger trial.

Background: Distal third fractures account for 10 to 15% of all clavicle fractures. Traditional management of displaced lateral third fractures has been with internal fixation. Several authors have reported higher rates of non-union and poor outcome in conservatively managed fractures. However, long term follow up of non-operated distal third fractures has shown comparable functional outcomes to those managed with internal fixation. The purpose of this retrospective study was to analyse the clinical and radiographic results of nonoperative treatment of displaced lateral clavicle fractures.

Methods: Eighty six patients with displaced lateral end clavicle fractures were treated primarily with a sling for comfort. The fractures were classified as Neer type IIa in fifty patients, type IIb in twenty nine and type III in seven. Physiotherapy was begun after the sling was removed at an average of two weeks after the injury. Patients were evaluated with regard to shoulder function and general health using a modification of the Constant score and SF-36 respectively. All patients had a repeat radiographic exam at follow up. The average duration of follow up was six years (range two to ten years).

Results: Fourteen patients developed symptoms severe enough to warrant surgery at between seven and twenty four months post-injury. Eleven had radiographically confirmed non-union and three had symptomatic osteoarthritis of the acromioclavicular joint. The remaining seventy two patients had not undergone any further surgery. Twenty one patients (29.2%) from the nonoperatively treated group had non-union of the clavicle fracture. The average adjusted Constant score in the non operated group was 94 (range 82 to 98). There was no significant difference in either Constant score or SF-36 between those with non-union and those fractures which had healed. There was also no significant difference in these scores between those treated nonoperatively and those treated by delayed surgery.

Conclusions: Nonoperative treatment of most displaced lateral third clavicle fractures can achieve good functional results comparable to those reported after surgical treatment. Surgery should be reserved for those with primary complications or for the minority who have painful non-union or acromioclavicular joint problems in the early stages of treatment.
