Outcome following management of unstable lateral end clavicle fractures with locking plate and coracoid anchor augmentation

BACKGROUND

Management of complex lateral end clavicle fractures with coraco-clavicular ligament disruption can be challenging.

METHODS

We prospectively analysed 19 (17 M:2F) patients from January 2014 to June 2016. Six patients had intra-articular fractures (Edinburgh-3B2) and the remaining were extra-articular (3B1). All patients had open reduction internal fixation with lateral end locking plate augmented with a coracoid anchor. All patients were evaluated at the final follow-up by American Shoulder and Elbow Surgeon score (ASES), Disabilities of the Arm, Shoulder and Hand (DASH), Oxford Shoulder Score (OSS), return to work, sports and radiographs.

RESULTS

At a mean follow-up of 54 months (range 37-64), 19 patients were available for analysis. Mean age of patients was 34 years (range 24-65). At final follow-up DASH score was 1.66 (range 0-5); ASES score was 98.14 (93.3-100) and OSS was 46.6 (42-48). There was no difference in the functional outcome between 3B1 and 3B2 fractures (DASH - p(0.51); ASES - p(0.44); OSS - p(0.69)). All patients returned to preinjury level of function, sports and work. Five patients needed implant removal and three developed capsulitis that resolved with conservative treatment.

CONCLUSION

Locking plate fixation, augmented with coracoid anchor is an effective option in the management of these complex injuries. The need for implant removal is reduced (26%) and there is no difference in the functional outcome between 3B1 and 3B2 fractures.

Management of open elbow fractures: experiences and outcomes from a UK major trauma center

HYPOTHESIS AND BACKGROUND

Open fractures about the elbow are an infrequent but complex injury with limited existing literature. The aims of the study were to review the treatment strategies of open elbows fractures, functional outcome and complication rates associated with the injury, and correlate the outcome with the topography of the fracture.

METHODS

Patients (n = 21) with open elbow fractures injuries over a 2-year period were analyzed. They were assessed regarding the orthoplastic characteristics of their injury as well any other associated injuries. Outcomes were assessed objectively (achievement of bony union, range of movement, infection status, need for further procedures) and subjectively (Oxford Elbow Score, EQ-5D, EQ-VAS).

RESULTS

The commonest grade of open injury was grade 3 (43%). Associated orthopedic injuries were present in 62% and associated system injuries in 57%. Almost half of the patients were noted to have had a significantly increased presenting mortality risk as per Injury Severity Score assessment. Mean time to first wound débridement was 31 hours. There were no cases of deep or chronic infection. Complete bony union was noted in 85% of patients, and 48% of patients required removal of metalwork. Subgroup analysis of the cohort by fracture topography (single unipolar elbow bone injury vs. multiple elbow bony injuries) demonstrated no significant difference (P > .05) regarding rate of complication or final Oxford Elbow Score, EQ-5D or EQ-VAS. Patients with injuries that involved the distal humerus had the highest rate for further procedures (P < .05). The average Oxford Elbow Score, EQ-5D, and EQ-VAS scores for the whole cohort at final follow-up were 37.4, 0.54, and 62.18, respectively.

DISCUSSION

Open elbow injuries are usually from high-energy trauma and often combined with other significant injuries. As a result, the timelines to elbow surgery were often delayed. However, this did not impact the local infection rates nor did it necessitate further surgery, but made achieving all British Orthopaedic Association Standards for Trauma targets difficult. Chronic infection was not an issue in this cohort. Subgroup analysis indicates open distal humerus fractures carry the highest risk for further procedures. This is most commonly in the form of removal of metalwork and fibrinolysis. End outcomes for patients with open elbow fractures can be positive, despite the notable presenting Injury Severity Score. A subspecialist elbow and orthoplastic approach whenever possible is advocated.

Is there a role for elbow arthrodesis in 21st Century - Current concepts and overview of surgical techniques

Elbow arthrodesis is uncommon and is usually performed as a salvage procedure to provide a stable elbow. There is a significant gap in the literature about the indications, contraindications, fusion angle, technical tips, and reversibility of the procedure. This review addresses these questions in a evidence based manner, based on the published literature.

Improving the efficiency of ankle fracture care through home care and day-surgery units: Delivering safe surgery on a value-based healthcare model

OBJECTIVES

Preoperative home care for suitable patients with ankle fractures is becoming an increasingly common practice. It allows adequate time for reduction of ankle swelling following a decision to undertake operative fixation has been made. We aim to assess the safety, efficiency, cost-effectiveness and differences in clinical & patient outcomes of day surgery unit (DSU) care for ankle fracture treatment in selected patients. Our study combined home therapy treatment with DSU care for suitable ankle fractures.

DESIGN

Prospective cohort study.

SETTING

Trauma Centre.

PATIENTS

Fifty-three patients requiring operative fixation for an ankle fracture were divided into 2 groups. Patients in group 1 entered the home care combined with DSU treatment pathway whilst in group 2 were treated as in patient in the main trauma theatre in our standard pathway.

INTERVENTION

Comparison of Home Care & Day Case Surgery vs. in patient admission for patients requiring operative ankle fractures fixation.

MAIN OUTCOME MEASURES

Prospective data collection was undertaken over a 2-year period, on fracture type, logistical outcomes including time to surgery and total length of stay in the hospital and clinical outcomes including the rate of post-operative complications, incidence of unplanned surgical revisions and objective patient satisfaction. Economic analysis was performed to compare the marginal cost saving per case for group 1 vs. group 2.

RESULTS

There were 21 patients in group 1. They waited for on average 5.8 days at home for their operation and none were admitted pre or post operatively. There were no associated complications and the majority of patients were discharged from follow-up at 6 weeks post-surgery. In-group 2, there were 32 patients. They waited on average 2.4 days for their operation in the hospital and had an average length of stay of 4.9 days. One patient in group 2 suffered from a deep vein thrombosis. The benefit from our chargeable tariff for group 1 patients was £2295 per case while the margin for group 2 patients was £277 per case. The financial benefit to the health care provider was £2018 in favour of home care and DSU treatment, with high service satisfaction and low complication rates.

DISCUSSION

This study provides focused evidence supporting the use of home care for the management of ankle fractures. The DSU pathway improves the value in healthcare delivery with high patient satisfaction scores when compared to the traditional pathway. Our model demonstrates predictably good clinical outcomes with a financial cost benefit over in-patient admission care model for selected patients.

Scaffolds in the management of massive rotator cuff tears: current concepts and literature review

Injuries to the rotator cuff (RC) are common and could alter shoulder kinematics leading to arthritis. Synthetic and biological scaffolds are increasingly being used to bridge gaps, augment RC repair and enhance healing potential. Our review evaluates the clinical applications, safety and outcome following the use of scaffolds in massive RC repair.

A search was performed using EBSCO-Hosted Medline, CINAHL, Cochrane and PubMed using various combinations of the keywords ‘rotator cuff’, ‘scaffold’, ‘biological scaffold’, ‘massive rotator cuff tear’ ‘superior capsular reconstruction’ and ‘synthetic scaffold’ between 1966 and April 2018. The studies that were most relevant to the research question were selected. All articles relevant to the subject were retrieved, and their bibliographies hand searched.

Synthetic, biosynthetic and biological scaffolds are increasingly being used for the repair/reconstruction of the rotator cuff. Allografts and synthetic grafts have revealed more promising biomechanical and early clinical results than xenografts. The retear rates and local inflammatory reactions were alarmingly high in earlier xenografts. However, this trend has reduced considerably with newer versions. Synthetic patches have shown lower retear rates and better functional outcome than xenografts and control groups.

The use of scaffolds in the treatment of rotator cuff tear continues to progress. Analysis of the current literature supports the use of allografts and synthetic grafts in the repair of massive cuff tears in reducing the retear rate and to provide good functional outcome. Though earlier xenografts have been fraught with complications, results from newer ones are promising. Prospective randomized controlled trials from independent centres are needed before widespread use can be recommended.

Swellings of the sternoclavicular joint: review of traumatic and non-traumatic pathologies

The sternoclavicular joint (SCJ) is an integral part of the shoulder girdle that connects the upper limb to the axial skeleton.

Swelling of the SCJ is commonly due to trauma, degeneration, infections and other disease processes that affect synovial joints.

This review also focuses on uncommon conditions that could affect the SCJ, including SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome, Friedrich’s disease and Tietze syndrome.

The scope of this review is limited to the analysis of the current evidence on the various conditions affecting the SCJ and also to provide an algorithm to manage these conditions.

Barriers to staff reporting adverse incidents in NHS hospitals

Our study assessed barriers to reporting adverse incidents (AIs). Adverse incident reporting (AIR), although it is a pillar of risk management, has a wide variation in staff perception and usage. A questionnaire was used in five NHS hospitals to assess 267 members of multidisciplinary team (MDT) staff usage of AIR. Thirty-three percent of staff had never reported an adverse incident (AI). Fourty-one percent of staff had missed opportunities to report AIs due to a poor response to previous reports. The group who missed opportunities had a significantly higher proportion of not having received feedback to their previous AI (p=0.03). In the group who had received training, 79% had submitted an AI. This was significantly higher than the group who had not received training (63%, p=0.02). Our study revealed that training and feedback following AIR are two major factors that could improve confidence in and use of AI reporting.

Intratendinous supraspinatus cyst as a cause of shoulder impingement

We report the case of a 29-year-old gentleman with shoulder impingement. An articular-sided intratendinous supraspinatus cyst was identified as the cause of his symptoms. Arthroscopic cyst debridement resulted in a good outcome at 1-year follow-up. Cysts around the shoulder are a well described pathological entity. They consist of different categories, including intraosseus cysts of the humeral head and glenoid, paralabral cysts and cysts associated with the acromioclavicular joint. Although paralabral cysts that lie intramuscularly or between the muscle bellies have frequently been reported, this is the first report of an intratendinous supraspinatus cyst with an intact rotator cuff. We describe the case, its management and the postsurgical outcome.

The influence of process and patient factors on the recall of consent information in mentally competent patients undergoing surgery for neck of femur fractures

INTRODUCTION

Informed consent is an ethical and legal prerequisite for major surgical procedures. Recent literature has identified 'poor consent' as a major cause of litigation in trauma cases. We aimed to investigate the patient and process factors that influence consent information recall in mentally competent patients (abbreviated mental test score [AMTS] ≥6) presenting with neck of femur (NOF) fractures.

METHODS

A prospective study was conducted at a tertiary unit. Fifty NOF patients (cases) and fifty total hip replacement (THR) patients (controls) were assessed for process factors (adequacy and validity of consent) as well as patient factors (comprehension and retention) using consent forms and structured interview proformas.

RESULTS

The two groups were matched for ASA (American Society of Anesthesiologists) grade and AMTS. The consent forms were adequate in both groups but scored poorly for validity in the NOF group. Only 26% of NOF patients remembered correctly what surgery they had while only 48% recalled the risks and benefits of the procedure. These results were significantly poorer than in THR patients (p = 0.0001).

CONCLUSIONS

This study confirms that NOF patients are poor at remembering the information conveyed to them at the time of consent when compared with THR patients despite being intellectually and physiologically matched. We suggest using preprinted consent forms (process factors), information sheets and visual aids (patient factors) to improve retention and recall.

Evidence that the kinase-truncated c-Src regulates NF-κB signaling by targeting NEMO

The tyrosine kinase c-Src and transcription factor NF-κB are considered crucial components required for normal osteoclastogenesis. Genetic ablation of either pathway leads to detrimental osteopetrotic phenotypes in mice. Similarly, obstruction of either pathway halts osteoclastogenesis and lessens various forms of bone loss. It has been shown previously that mice expressing a kinase domain-truncated c-Src, termed Src251, develop severe osteopetrosis owing to increased osteoclast apoptosis. It was further suggested that this phenomenon is associated with reduced Akt kinase activity. However, the precise mechanism underlying the osteoclast inhibitory effect of Src251 remains obscure. C-Src associates with TRAF6-p62 interacting with receptor activator of NF-κB (RANK) distal region and the complex facilitate activation of RANK down stream signal transduction cascades including NF-κB. Given this proximity between c-Src and NF-κB signaling in osteoclasts, we surmised that inhibition of osteoclastogenesis by Src251 may be achieved through inhibition of NF-κB signaling. We have demonstrated recently that NEMO, the regulatory subunit of the IKK complex, is crucial for osteoclastogenesis and interacts with c-Src in osteoclast progenitors. Transfection studies, in which we employed various forms of c-Src and NEMO, revealed that the dominant negative form of c-Src, namely Src251, mediates degradation of NEMO thus halting NF-κB signaling. Furthermore, degradation of NEMO requires its intact zinc finger domain which is located at the ubiquitination domain. This process also requires appropriate cellular localization of Src251, since deletion of its myristoylation domain ablates its degradation capacity. Buttressing these findings, the expression of NEMO and NF-κB signaling were significantly reduced in monocytes collected from Src251 transgenic mice.
