The impact of COVID-19 pandemic on the mortality and morbidity of patients undergoing trauma surgery: a report from the UK Corona TRAUMA Surge (UKCoTS) study. INTERNATIONAL ORTHOPAEDICS 2023; 47:1397-1405. [PMID: 36897361 PMCID: PMC9999070 DOI: 10.1007/s00264-023-05718-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Accepted: 01/29/2023] [Indexed: 03/11/2023] [Imported: 09/11/2023]
Abstract
PURPOSE To assess the impact of the COVID-19 pandemic on the outcomes of the patients who underwent trauma surgery during the peak of the pandemic. METHODS The UKCoTS collected the postoperative outcomes of consecutive patients who underwent trauma surgery across 50 centres during the peak of the pandemic (April 2020) and during April 2019. RESULTS Patients who were operated on during 2020 were less likely to be followed up within a 30-day postoperative period (57.5% versus 75.6% p <0.001). The 30-day mortality rate was significantly higher during 2020 (7.4% versus 3.7%, p <0.001). Likewise, the 60-day mortality rate was significantly higher in 2020 than in 2019 (p <0.001). Patients who were operated on during 2020 had lower rates of 30-day postoperative complications (20.7% versus 26.4%, p <0.001). CONCLUSIONS Postoperative mortality was higher during the first wave of the COVID-19 pandemic compared to the same period in 2019, but with lower rates of postoperative complications and reoperation.

Abstract
Anterior shoulder instability with bone loss is a challenging condition. The two most performed procedures, Bankart repair & Latarjet, are not without issues. We describe a technique where arthroscopic free bone grafting was performed in conjunction with remplissage. We feel that this combined arthroscopic procedure offers advantages that include reduced risk of conventional Latarjet complications, including neurological deficits and metal hardware complications while preserving subscapularis and coracoid. Furthermore, these advantages may not come at the cost of compromised outcomes, particularly recurrence rate, as the remplissage may compensate for the possible lack of "sling effect" with free bone graft reconstruction.

[PMID: 36452419 PMCID: PMC9702027 DOI: 10.22038/abjs.2022.61345.3012] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Accepted: 01/17/2022] [Indexed: 01/25/2023] [Imported: 09/11/2023]
Abstract
BACKGROUND Repair of massive rotator cuff tears remains a challenging process with mixed success. There is a growing interest in the use of patches to augment the repair construct and the potential to enhance the strength, healing, and associated clinical outcomes. Such patches may be synthetic, xenograft, or autograft/allograft, and a variety of techniques have been tried to biologically enhance their integration and performance. The materials used are rapidly advancing, as is our understanding of their effects on rotator cuff tissue. This article aims to evaluate what we currently know about patch augmentation through a comprehensive review of the available literature. METHODS We explore the results of existing clinical trials for each graft type, new manufacturing methods, novel techniques for biological enhancement, and the histological and biomechanical impact of patch augmentation. RESULTS There are promising results in short-term studies, which suggest that patch augmentation has great potential to improve the success rate. In particular, this appears to be true for human dermal allograft, while porcine dermal grafts and some synthetic grafts have also had promising results. CONCLUSION However, there remains a need for high-quality, prospective clinical trials directly comparing each type of graft and the effect that they have on the clinical and radiological outcomes of rotator cuff repair.

Abstract
This systematic review of the literature aims to analyse current knowledge to inform choice between hemiarthroplasty (HA) and reverse total shoulder arthroplasty (rTSA) for managing proximal humerus fractures (PHF) in elderly patients; the aim is to understand if rTSA can be considered the gold standard for treating PHF in the elderly when surgical fixation or conservative treatment is not viable options. Studies reporting outcomes and complications of PHF treated with shoulder arthroplasty in the elderly were included. Studies were in English and published after 2008. Evidence levels I, II, III and IV were included. According to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a comprehensive literature search was conducted using Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature) and PubMed search engines, as well as the Cochrane Central Register of Controlled Trials. General data collected were study design, number of patients treated with HA and rTSA, age of patients (mean, mean and SD, mean and range), length of follow-up, type of implant, and clinical outcomes. rTSA can be regarded as the gold standard for surgical management of displaced 3 and 4-part fractures in the elderly. However, the literature offers mostly low-quality studies, thereby requiring further work to achieve a full understanding of this important topic.

Abstract
OBJECTIVES To investigate the impact of COVID-19 on the well-being of surgeons and allied health professionals as well as the support provided by their institutions. DESIGN This cross-sectional study involved distributing an online survey through medical organisations, social media platforms and collaborators. SETTING It included all staff based in an operating theatre environment around the world. PARTICIPANTS 1590 complete responses were received from 54 countries between 15 July and 15 December 2020. The average age of participants was 30-40 years old, 64.9% were men and 32.5% of a white ethnic background. 79.5% were surgeons with the remainder being nurses, assistants, anaesthetists, operating department practitioners or classified other. MAIN OUTCOME MEASURES Participants that had experienced any physical illness, changes in mental health, salary or time with family since the start of the pandemic as well as support available based on published recommendations. RESULTS 32.0% reported becoming physically ill. This was more likely in those with reduced access to personal protective equipment (OR 4.62; CI 2.82 to 7.56; p<0.001) and regular breaks (OR 1.56; CI 1.18 to 2.06; p=0.002). Those with a decrease in salary (29.0%) were more likely to have an increase in anxiety (OR 1.50; CI 1.19 to 1.89; p=0.001) and depression (OR 1.84; CI 1.40 to 2.43; p<0.001) and those who spent less time with family (35.2%) were more likely to have an increase in depression (OR 1.74; CI 1.34 to 2.26; p<0.001). Only 36.0% had easy access to occupational health, 44.0% to mental health services, 16.5% to 24/7 rest facilities and 14.2% to 24/7 food and drink facilities. Fewer measures were available in countries with a low Human Development Index. CONCLUSIONS This work has highlighted a need and strategies to improve conditions for the healthcare workforce, ultimately benefiting patient care.

Abstract
Lunotriquetral (LT) ligament tear, usually in combination with an adjacent carpal ligament injury, can result in complete LT dissociation and VISI (Volarflexed Intercalated Segment Instability). Operative techniques for the management of instability are highly variable with many described in literature, although there is little evidence to demonstrate the superiority of one definitive therapeutic technique of repair and reconstruction. In this paper, we discuss our proposed technique for performing LT ligament repair using an augmented internal brace, which addresses triquetral extension and lunate flexion. The internal brace construct also provides biomechanical superiority as it includes the augmentation of the ligament and capsule repair. We use figures and references from our case example to demonstrate this technique.

Abstract
BACKGROUND The aim of our prospective multicentre study is to evaluate the five-year follow-up outcomes of primary reverse shoulder replacement utilizing two different designs of glenoid baseplates. METHODS There were 159 reverse shoulder replacements (91 cemented and 68 uncemented stems, 67 Trabecular Metal baseplates and 92 Anatomical Shoulder baseplates in 152 patients (99 women) with a mean age of 74.5 (58-90) years. The principal diagnosis was rotator cuff arthropathy in 108 shoulders. RESULTS Clinical and functional results improved significantly overall; the adjusted Constant Murley score improved from 28.2 ± 13.3 pre-operatively to 75.5 ± 22.8 (p < 0.0001) and the mean Subjective Shoulder Value improved from 27.5 ± 20 to 73.8 ± 21.3 points (p < 0.0001). Radiologically, there was good bony stability in 88% and 86% of cemented and uncemented stems without significant impact on the Constant Murley score and Subjective Shoulder Value at one, two and five years post-surgery. There were no significant clinical differences between Trabecular Metal and Anatomical Shoulder baseplates at five years. There were four cases of intraoperative shaft fractures that were managed with cables. Although the Trabecular Metal baseplates showed better integration radiologically, there was no significant difference in the mean of Constant Murley, Subjective Shoulder Value and the range of motion depending on the grade of inferior scapular notching at one-, two- and five-year intervals. CONCLUSIONS Reverse total shoulder arthroplasty restores the function in shoulder with significant improvements in function and moderate complications with minor differences between both designs of baseplates that were not reflected clinically.

Abstract
BACKGROUND This study aims to demonstrate the impact of the COVID-19 pandemic on providing trauma services at our district general hospital. We aim to identify the impact on specific areas of theatre delay to help optimize theatre efficiency and generate better protocols and improve patient flow for future pandemic waves. METHODS Patients who underwent orthopaedic trauma surgery at our hospital between July-August 2019 (pre-COVID-19) and 2020 (first UK wave of COVID-19) were identified retrospectively and grouped by year of operation. Type of operation was recorded, including time for sending, anaesthetic induction, surgical preparation, operating time, and time for transfer to recovery. The two groups were compared for analysis. RESULTS Case numbers were similar in both 2019 and 2020 (215vs.213 operations), with a similar proportion being hip fractures (39.1% and 36.6%), respectively. Median sending time (40vs.23 minutes, P <0.00001) and induction time (13vs.8 minutes, P<0.00001) were increased in 2020, a 74% and 63% increase compared to 2019, respectively. Median surgical preparation time (35vs.37 minutes, P=0.06) and operating time (56vs.50 minutes, P=0.16) were not statistically significant. Transfer time in 2020 (16vs.13 minutes, P<0.00001) was significantly increased. Overall case time increased in 2020 (2:40vs.2:11, P<0.00001) by 29 minutes. CONCLUSION COVID-19 had a significant impact on theatre efficiency in our hospital, causing multiple points of delay. As hospitals across the UK restart crucial elective services, focus should be given to maximizing theatre efficiency by providing rapid access COVID-19 testing for patients undergoing emergency surgery. We have proposed and implemented several steps for better theatre utilization.

THE ARCHIVES OF BONE AND JOINT SURGERY 2021; 9:527-535. [PMID: 34692935 DOI: 10.22038/abjs.2021.52827.2654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Accepted: 02/08/2021] [Indexed: 11/06/2022] [Imported: 09/11/2023]
Abstract
Background The aim of our study is to report the clinical and radiological outcomes of a series of prospectively enrolled patients who have had double-row transosseous equivalent rotator cuff repairs, where all-suture anchors were used as medial-row anchors, with a minimum follow-up of 1 year. Methods Twenty-two consecutive patients underwent arthroscopic transosseous equivalent double-row rotator cuff repair using all-suture anchors as medial-row anchors. Oxford Shoulder Score, Constant Score and Visual Analogue Scale pain score, together with shoulder range of motion, were used preoperatively and at 3 months, 6 months and final follow-up. Radiological evaluation was performed with magnetic resonance imaging at one-year post surgery to assess the structural integrity of the repair and the rate of cyst formation in greater tuberosity. Results The patient mean age was 61 years (range 46-75). Minimum follow-up was 1 year, and the mean final follow-up was 15 months (range 12-24). Healing failure in our patients was less than 5% (1/22 patients). There were significant improvements in shoulder function outcome scores at final follow-up. The Constant and Oxford scores were 78 and 44 at final follow-up respectively. There were similar magnitudes of improvement in range of motion (combined abduction and rotation), pain score and supraspinatus strength at final follow up. The improvements in outcome scores were already statistically significant at 3 months (P<.001). Using Kim's classification for cyst formation on T2-weighted MRI images, we observed no fluid or minimal fluid collection in 85% of the patients (17/22 patients). There were no correlations between the grade of bone changes and the clinical outcomes. Conclusion It is safe to use all-suture anchors as medial-row anchors when performing double-row anchor transosseous equivalent rotator cuff repairs. The purported advantages of all-suture anchors may outweigh their perceived disadvantages in rotator cuff repair surgery.

Abstract
BACKGROUND Little consensus is available regarding the standard treatment for recurrent anterior instability of the shoulder. Typically, treatment selection has been based on training and tradition rather than the available evidence. PURPOSE This study aimed to compare the clinical outcomes between arthroscopic Bankart procedure and the Latarjet procedure in the treatment of recurrent anterior shoulder instability with emphasis on follow-up time. STUDY DESIGN Systematic review and meta-analysis. METHODS We searched PubMed, Cochrane Central Register of Controlled Trials, Scopus, Ovid, and Web of Science up to January 2018 and included studies that compared arthroscopic Bankart versus Latarjet for treatment of anterior shoulder instability. Continuous data, such as operative time and patient-reported outcomes, were pooled as mean differences (MDs), whereas dichotomous data, such as recurrence, revision, redislocation, arthropathy, infection, and hematoma, were pooled as risk ratios (RRs), with 95% CIs. RESULTS Pooling data from 7 cohort studies (3275 patients) showed that arthroscopic Bankart was associated with a higher risk of redislocation (RR, 2.74; 95% CI, 1.48-5.06; P = .03), a higher risk of recurrence (RR, 2.87; 95% CI, 1.91-4.30; P < .0001), and a lower risk of infection (RR, 0.16; 95% CI, 0.06-0.43; P = .0002) compared with Latarjet, while the effect size did not favor arthroscopic Bankart or Latarjet in terms of Rowe score (MD, 0.22; 95% CI, -5.64 to 6.08; P = .94), revision (RR, 0.34; 95% CI, 0.08-1.39; P = .13), and hematoma (RR, 0.20; 95% CI, 0.03-1.19; P = .07). The effect estimate showed a pronounced advantage for Latarjet from 6 to 10 years postoperatively in terms of recurrence and redislocation (RR, 3.00; 95% CI, 1.98-4.56 and RR, 2.85; 95% CI, 1.51-5.38, respectively). CONCLUSION Our results showed that Latarjet had less risk of recurrence and redislocation with longer follow-up time. Both procedures were comparable in terms of Rowe score, the need for revision, and postoperative hematoma formation, whereas Bankart repair was associated with a lower risk of infection.

Abstract
BACKGROUND Reverse shoulder arthroplasty (RSA) has revolutionized the management of many shoulder pathologies. Lateralization has become favourable to combat complications (e.g. notching, compromised external rotation), using a metallic, or autogenous bone-graft baseplates - bony increased-offset reverse shoulder arthroplasty (BIO-RSA). We systematically reviewed the literature to determine: Does BIO-RSA improve range of motion and outcome scores?Are notching rates decreased?Does the graft heal? METHODS All available prospective studies, trials and case series reporting on BIO-RSA were included. Outcomes were grouped into outcome scores, range of motion and radiographic outcomes. Data were pooled and statistical analysis performed. RESULTS Eight studies reported on 385 RSA - 235 BIO-RSA and 150 standard-RSA (STD-RSA). Follow-up was 20-36 months; average age 74 years. Outcome scores: Constant-Murley and SSV scores showed statistically significant post-operative benefit of BIO-RSA (mean-difference 4.0 (95% confidence interval (CI): 0.79,7.1) and 6.8 (95% CI: 3.8, 9.9)). No Minimal Clinically Importance Difference was surpassed. Range of motion: No difference was found in any direction. Notching: Notching was less likely with BIO-RSA (odds ratio 0.19 (95% CI: 0.10, 0.38)). Healing and loosening: 92% grafts fully healed/incorporated. Loosening rate was 2.4%. CONCLUSIONS Literature on BIO-RSA is limited with only one randomised controlled trial (RCT). Weak evidence exists for improved outcome scores. Range of motion is equivocal. Notching rates are significantly lower in BIO-RSA. The graft usually heals.

Abstract
Posterior shoulder dislocation, whilst uncommon, is frequently missed and often associated with a significant defect on the antero-medial aspect of the humeral head (the reverse Hill-Sachs lesion). Several techniques for stabilisation have been described, depending on the size of the lesion. We describe an additional technique for stabilising the shoulder following posterior dislocation by augmenting the reverse Hill-Sachs lesion with layers of extracellular matrix, thus further filling the defect.

Abstract
BACKGROUND To investigate the geometric development of the wrist in relation to the changes in its ossification pattern. This study will help the treating surgeon to identify early deviations from normal in children with musculoskeletal disorders and provide a template for anatomic reduction after trauma scenarios. METHODS A retrospective multicenter analysis was carried out of radiographs of 896 children (896 posteroanterior and 896 lateral views) with normal wrists from January 1996 till April 2016. We stratified patients into different yearly age groups; these included 16 age groups from 1 to 16 years, and 2 sex groups: males and females. We evaluated, depending on the wrist ossification pattern, the ulnar variance, radial and carpal heights, carpal height ratio, radial inclination, volar tilt, together with radiocarpal, scapholunate, and capitate-lunate angles and scapholunate distance. RESULTS Our analysis showed that the ulna minus variance predominates in children. Radial height, radial inclination, and radiocarpal angle increase steadily during growth and reach their respective expected values at the beginning of the pubertal growth spurt. The scapholunate and capitolunate angles showed a downward trend with growth till reaching the adult values at puberty. Carpal height increased constantly, whereas the carpal height ratio was similar to that in adults. Volar tilt was not developed until the age of 12 years, when it started to increase gradually to reach the adult values by puberty. Both sexes have similar measurements. CONCLUSIONS Most radiologic parameters showed reproducible anatomic changes till the 12-year-old time-point. After that, there are minimal changes till adulthood. CLINICAL RELEVANCE The study findings offer a template of pediatric normal values guiding hand and pediatric surgeons in treatment of children with wrist pathology.

[PMID: 33082721 PMCID: PMC7534891 DOI: 10.1007/s11420-020-09769-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Accepted: 06/04/2020] [Indexed: 02/07/2023] [Imported: 09/11/2023]
Abstract
BACKGROUND Hip hemiarthroplasty is a well-established treatment of displaced femoral neck fracture, although debate exists over whether cemented or uncemented fixation is superior. Uncemented prostheses have typically been used in younger, healthier patients and cemented prostheses in older patients with less-stable bone. Also, earlier research has suggested that bone cement has cytotoxic effects and may trigger cardiovascular and respiratory adverse events. QUESTIONS/PURPOSES The aim of this systematic review and meta-analysis was to compare morbidity and mortality rates after cemented and uncemented hemiarthroplasty for the treatment of displaced femoral neck fractures in elderly patients. METHODS Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched seven medical databases for randomized clinical trials and observational studies. We compared cemented and uncemented hemiarthroplasty using the Harris Hip Score (HHS), as well as measures of postoperative pain, mortality, and complications. Data were extracted and pooled as risk ratios or standardized mean difference with their corresponding 95% confidence intervals in a meta-analysis model. RESULTS The meta-analysis included 34 studies (12 randomized trials and 22 observational studies), with a total of 42,411 patients. In the pooled estimate, cemented hemiarthroplasty was associated with less risk of postoperative pain than uncemented hemiarthroplasty. There were no significant differences between groups regarding HHS or rates of postoperative mortality, pulmonary embolism, cardiac arrest, myocardial infarction, acute cardiac arrhythmia, or deep venous thrombosis. CONCLUSIONS While we found that cemented hemiarthroplasty results in less postoperative pain than uncemented hemiarthroplasty in older patients with femoral neck fracture, the lack of significant differences in functional hip scores, mortality, and complications was surprising. Further high-level research is needed.

Three-year functional outcome of transosseous-equivalent double-row vs. single-row repair of small and large rotator cuff tears: a double-blinded randomized controlled trial. J Shoulder Elbow Surg 2020; 29:2015-2026. [PMID: 32951642 DOI: 10.1016/j.jse.2020.05.005] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2019] [Revised: 04/24/2020] [Accepted: 05/04/2020] [Indexed: 02/01/2023] [Imported: 09/11/2023]
Abstract
BACKGROUND The trial aimed to prospectively compare the functional outcomes of patients undergoing arthroscopic rotator cuff repair using transosseous-equivalent double-row (TEDR) or single-row (SR) suture anchor techniques at 3 years postoperatively for both large (>3 cm) and small (<3 cm) tears. METHODS Eighty patients with a symptomatic and magnetic resonance imaging (MRI)-proven full-thickness rotator cuff tear, who had failed conservative management of at least 6 months' duration and who had a complete passive range of motion of the affected shoulder, were enrolled in the trial. Patients were randomized to TEDR repair (n = 40) or SR repair (n = 40). Subgroup analysis was conducted for tears <3 cm (TEDR n = 17, SR n = 19) and tears >3 cm (TEDR n = 23, SR n = 21). Primary outcomes included the Oxford Shoulder Score (OSS), the University of California, Los Angeles (UCLA) score, and the Constant-Murley score (CMS). The secondary outcomes included a 0-100-mm visual analog scale (VAS) score for pain, range of motion (ROM), and EQ-5D scores. All patients completed a follow-up of 3 years. RESULTS There was a significant difference in the mean OSS postoperative score for tears >3 cm (P = .01) and mean improvement from baseline in the TEDR group (P = .001). For tears >3 cm, mean postoperative scores were also significantly higher in the TEDR group for UCLA (P = .015) and CMS (P = .001). Post hoc testing showed that the differences between these groups was statistically significant (P < .05). For tears <3 cm, a significant postoperative difference in favor of SR repair was seen in the mean CMSs (P = .011), and post hoc testing showed that the difference was statistically significant (P = .015). No significant difference was seen with mean postoperative OSS or UCLA, and post hoc testing did not show a statistically significant difference between groups. CONCLUSIONS TEDR repair showed improved functional outcomes for tears >3 cm compared with SR repair. For tears <3 cm, no clear benefit was seen with either technique.

Aerosol generating procedures in trauma and orthopaedics in the era of the Covid-19 pandemic; What do we know? Surgeon 2020; 19:e42-e48. [PMID: 32883580 PMCID: PMC7425761 DOI: 10.1016/j.surge.2020.08.001] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 07/01/2020] [Accepted: 08/01/2020] [Indexed: 01/02/2023] [Imported: 09/11/2023]
Abstract
Purpose COVID-19 pandemic has created havoc all over the globe and spared no one regardless of status, gender, location and ethnicity. There were questions raised if trauma and orthopaedic (T&O) procedures actually generated aerosols? The need for a review of literature highlighting the nature and impact of aerosol generation within T&O surgery was noted. Methods A comprehensive online search was performed for all published articles in the English language, evaluating AGPs in T&O surgery and the relevant personal protection equipment used. Results The search strategy populated 43 studies. Six studies were identified as duplicates. The shortlisted 37 studies were screened and nine studies were included in the review. An additional four studies were included from the bibliography review. Conclusion Most orthopaedic procedures are high-risk aerosol generating procedures (AGPs). Conventional surgical masks do not offer protection against high-risk AGPs. In the current era of COVID-19 pandemic, there is a significant risk to the transmission of infection to the theatre staff. For protection against airborne transmission, appropriate masks should be used. These need proper fitting and sizing to ensure full protection when used.

Abstract
Despite profound advancements in arthroscopic rotator cuff repair (RCR) techniques, radiologic failure rates may be in excess of 60% with repairs of large and massive tears in the elderly population. One of the strategies to improve these healing rates has been "patch" augmentation of the cuff repair. At the same time, superior capsular reconstruction (SCR) has gained significant popularity as an option for irreparable rotator cuff (RC) tears. Some have also advocated performing SCR in addition to arthroscopic RCR to reinforce the repair and improve healing rates. Techniques involving the use of fascia lata, ECM patches, and long head of the biceps (LHB) for SCR to reinforce the cuff repair have all been elegantly described. In this article, we propose a technique that enables a combination of the aforementioned procedures and involves performing RCR with patch augmentation, as well as SCR using LHB. In doing so, the repaired RC is bordered by the patch over its bursal surface and the LHB on the articular surface (functioning as the superior capsule), thus giving us the name "Hamburger technique" (a 3-layered construct).

Abstract
HYPOTHESIS Is salvage reverse total shoulder arthroplasty (RTSA) a justifiable treatment for failed operative treatment (open reduction-internal fixation [ORIF] or primary and secondary hemiarthroplasty) of proximal humeral fractures in patients younger than 60 years? METHODS Thirty patients (mean age, 52 years; age range, 30-59 years) were reviewed after a mean follow-up period of 11 years (range, 8-18 years). Of the patients, 7 (23%) underwent RTSA for failed ORIF and 23 (77%) for failed hemiarthroplasty. Clinical and radiographic outcomes were assessed longitudinally. RESULTS At final follow-up, the mean relative Constant score had improved from 25% (±12%) to 58% (±21%, P < .001). Significant improvements were seen in the mean Subjective Shoulder Value (20% to 56%), active elevation (45° to 106°), abduction (42° to 99°), pain scores, and strength (P < .001). Clinical outcomes did not significantly deteriorate over a period of 10 years. Patients with salvage RTSA for failed secondary hemiarthroplasty (n = 8) vs. those for failed ORIF (n = 6) showed significantly inferior active abduction (77° vs. 116°, P = .023). Patients with a healed greater tuberosity (n = 9) showed significantly better external rotation than patients with a resorbed/resected greater tuberosity (n = 13, 21° vs. 3°, P = .025). One or more complications occurred in 18 shoulders (60%), and 6 (20%) resulted in explantation of the RTSA. CONCLUSIONS Salvage RTSA in patients younger than 60 years is associated with a high complication rate. It leads nonetheless to substantial and durable improvement beyond 10 years, provided the complications can be handled with implant retention. Inferior shoulder function is associated with greater tuberosity resorption or resection and inferior overhead elevation with the diagnosis of failed hemiarthroplasty.

Abstract
AIMS Accurate measurement of the glenoid version is important in performing total shoulder arthroplasty (TSA). Our aim was to evaluate the Ellipse method, which involves formally defining the vertical mid-point of the glenoid prior to measuring the glenoid version and comparing it with the 'classic' Friedman method. METHODS This was a retrospective study which evaluated 100 CT scans for patients who underwent a primary TSA. The glenoid version was measured using the Friedman and Ellipse methods by two senior observers. Statistical analyses were performed using the paired t-test for significance and the Bland-Altman plot for agreement. RESULTS The mean glenoid version was -3.11° (-23.8° to 17.9°) using the Friedman method and -1.95° (-29.8° to 24.6°) using the Ellipse method (p = 0.002). In 16 patients the difference between methods was greater than 5°, which we considered to be clinically significant. There was poor agreement between methods with relatively large 95% limits of agreement. There was excellent inter-rater agreement between the observers for the Ellipse method and similarly, the intrarater agreement was excellent with a repeatability coefficient of 0.94. CONCLUSION We recommend the use of the Ellipse modification to define the mid glenoid point prior to measuring the glenoid version in patients undergoing TSA.

Abstract
Despite advances in metallurgy, fatigue failure of hardware in orthopaedics is common especially when a fracture fails to heal. Revision procedures can be difficult, usually requiring removal of intact or broken hardware. Several different methods are usually used to successfully remove the intact or broken hardware. The proximal blade fracture is rare and under-reported in the literature. In our tertiary non-union and limb reconstruction unit, we have developed a technique for an easy and quick removal of a broken proximal femoral blades.

Abstract
INTRODUCTION We review the literature and highlight the important factors to consider when counselling patients with non-traumatic rotator cuff tears on which route to take. Factors include the clinical outcomes of surgical and non-surgical routes, tendon healing rates with surgery (radiological outcome) and natural history of the tears if treated non-operatively. METHODS A PRISMA-compliant search was carried out, including the online databases PubMed and Embase™ from 1960 to the end of June 2018. FINDINGS A total of 49 of the 743 (579 PubMed and 164 Embase™) results yielded by the preliminary search were included in the review. There is no doubt that the non-surgical route with an appropriate physiotherapy programme has a role in the management of degenerative rotator cuff tears. This is especially the case in patients with significant risk factors for surgery, those who do not wish to go through a surgical treatment and those with small, partial and irreparable tears. However, rotator cuff repair has a good clinical outcome with significant improvements in pain, range of motion, strength, quality of life and sleep patterns.

Abstract
PURPOSE To assess the clinical outcomes of unipolar versus bipolar hemiarthroplasty for displaced intracapsular femoral neck fractures in older patients and to report whether bipolar implants yield better long-term functional results. METHODS We searched PubMed, Scopus, EBSCO, and Cochrane Library for relevant randomized clinical trials (RCTs) and observational studies, comparing unipolar and bipolar hemiarthroplasty. Data were extracted from eligible studies and pooled as relative risk (RR) or mean difference (MD) with corresponding 95% confidence intervals (CI) using RevMan software for Windows. RESULTS A total of 30 studies were included (13 RCTs and 17 observational studies). Analyses included 30,250 patients with a mean age of 79 years and mean follow-up time of 24.6 months. The overall pooled estimates showed that bipolar was superior to unipolar hemiarthroplasty in terms of hip function, range of motion and reoperation rate, but at the expense of longer operative time. In the longer term the unipolar group had higher rates of acetabular erosion compared to the bipolar group. There was no significant difference in terms of hip pain, implant related complications, intraoperative blood loss, mortality, six-minute walk times, medical outcomes, and hospital stay and subsequently cost. CONCLUSIONS Bipolar hemiarthroplasty is associated with better range of motion, lower rates of acetabular erosion and lower reoperation rates compared to the unipolar hemiarthroplasty but at the expense of longer operative time. Both were similar in terms of mortality, and surgical or medical outcomes. Future large studies are recommended to compare both methods regarding the quality of life.

Abstract
Background Neck of femur fractures and their subsequent operative fixation are associated with high rates of perioperative morbidity and mortality. Consenting in this setting is suboptimal with the Montgomery court ruling changing the perspective of consent. This quality improvement project assessed the adequacy of consenting against British Orthopaedic Association-endorsed guidance and implemented a series of changes to improve the documentation of risks associated with surgery for fractured neck of femur. Methods Seventy consecutive patients who underwent any operative fixation of a neck of femur fracture were included over a 6-month period at a single centre. Patients unable to consent or without electronic notes were excluded. Consent forms were analysed and the documented potential risks or complications associated with surgery were compared to British Orthopaedic Association-endorsed guidance. A series of changes (using the plan, do study, act (PDSA) approach) was implemented to improve the adequacy of consent. Results Documentation of four out of 12 potential risks or complications was recorded in <50% of cases for patients with intracapsular fractures (n=35), and documentation of seven out of 12 potential risks or complications was recorded in <50% of cases for patients with extracapsular fractures (n=35). Re-audit following raising awareness and attaching consent guidance showed 100% documentation of potential risks or complications in patients with intracapsular and extracapsular fractures (n=70). A neck of femur fracture-specific consent form has been implemented which will hopefully lead to sustained improvement. Conclusions Consenting patients with fractured neck of femur for surgery in the authors' unit was suboptimal when compared to British Orthopaedic Association-endorsed consent guidance. This project has shown that ensuring such guidance is readily available has improved the adequacy of consent. The authors hope that introduction of a neck of femur fracture-specific consent form within their unit will lead to sustained adequate documentation of risks associated with surgery.
