Aims

The aim of this study was to perform the first population-based description of the epidemiological and health economic burden of fracture-related infection (FRI).

Mirels’ score predicts the likelihood of sustaining pathological fractures using pain, lesion site, size and morphology. The aim is to investigate its reproducibility, reliability and accuracy in upper limb bony metastases and validate its use in pathological fracture prediction.

A retrospective cohort study of patients with upper limb metastases, referred to an Orthopaedic Trauma Centre (2013–18). Mirels’ was calculated in 32 patients; plain radiographs at presentation scored by 6 raters. Radiological aspects were scored twice by each rater, 2-weeks apart. Inter- and intra-observer reliability were calculated (Fleiss’ kappa test). Bland-Altman plots compared variances of individual score components &total Mirels’ score.

Mirels’ score of ≥9 did not accurately predict lesions that would fracture (11% 5/46 vs 65.2% Mirels’ score ≤8, p<0.0001). Sensitivity was 14.3% &specificity was 72.7%. When Mirels’ cut-off was lowered to ≥7, patients were more likely to fracture (48% 22/46 versus 28% 13/46, p=0.045). Sensitivity rose to 62.9%, specificity fell to 54.6%. Kappa values for interobserver variability were 0.358 (fair, 0.288–0.429) for lesion size, 0.107 (poor, 0.02–0.193) for radiological appearance and 0.274 (fair, 0.229–0.318) for total Mirels’ score. Values for intraobserver variability were 0.716 (good, 95% CI 0.432–0.999) for lesion size, 0.427 (moderate, 95% CI 0.195–0.768) for radiological appearance and 0.580 (moderate, 0.395–0.765) for total Mirels’ score.

We showed moderate to substantial agreement between &within raters using Mirels’ score on upper limb radiographs. Mirels’ has poor sensitivity &specificity predicting upper limb fractures - we recommend the cut-off score for prophylactic surgery should be lower than for lower limb lesions.

The Trauma Triage clinic (TTC) is a Virtual Fracture clinic which permits the direct discharge of simple, isolated fractures from the Emergency Department (ED), with consultant review of the clinical notes and radiographs. This study details the outcomes of patients with such injuries over a four-year period.

All TTC records between January 2014 and December 2017 were collated from a prospective database. Fractures of the radial head, little finger metacarpal, fifth metatarsal, toe phalanges and soft tissue mallet finger injuries were included. Application of the direct discharge protocol, and any deviations were noted. All records were then re-assessed at a minimum of three years after TTC triage (mean 4.5 years) to ascertain which injuries re-attended the trauma clinic, reasons for re-attendance, source of referral and any subsequent surgical procedures.

6709 patients with fractures of the radial head (1882), little finger metacarpal (1621), fifth metatarsal (1916), toe phalanges (920) and soft tissue mallet finger injures (370) were identified. 963 (14%) patients were offered in-person review after TTC, of which 45 (0.6%) underwent a surgical intervention. 299 (4%) re-attended after TTC direct discharge at a mean time after injury of 11.9 weeks and 12 (0.2%) underwent surgical intervention. Serious interventions, defined as those in which a surgical procedure may have been avoided if the patient had not undergone direct discharge, occurred in 1 patient (0.01%).

Re-intervention after direct discharge of simple injuries of the elbow, hand and foot is low. Unnecessary deviations from protocol offer avenues to optimise consumption of service resources.

Aims

The aim of this study was to explore current use of the Global Fragility Fracture Network (FFN) Minimum Common Dataset (MCD) within established national hip fracture registries, and to propose a revised MCD to enable international benchmarking for hip fracture care.

As arthroplasty demand grows worldwide, the need for a novel cost-effective treatment option for articular cartilage (AC) defects tailored to individual patients has never been greater. 3D bioprinting can deposit patient cells and other biomaterials in user-defined patterns to build tissue constructs from the “bottom-up,” potentially offering a new treatment for AC defects.

Novel composite bioinks were created by mixing different ratios of methacrylated alginate (AlgMA) with methacrylated gelatin (GelMA) and collagen. Chondrocytes and mesenchymal stem cells (MSCs) were then encapsulated in the bioinks and 3D bioprinted using a custom-built extrusion bioprinter. UV and double-ionic (BaCl2 and CaCl2) crosslinking was deployed following bioprinting to strengthen bioink stability in culture. Chondrocyte and MSC spheroids were also bioprinted to accelerate cell growth and development of ECM in bioprinted constructs.

Excellent viability of chondrocytes and MSCs was seen following bioprinting (>95%) and maintained in culture, with accelerated cell growth seen with inclusion of cell spheroids in bioinks (p<0.05). Bioprinted 10mm diameter constructs maintained shape in culture over 28 days, whilst construct degradation rates and mechanical properties were improved with addition of AlgMA (p<0.05). Composite bioinks were also injected into in vitro osteochondral defects and crosslinked in situ, with maintained cell viability and repair of osteochondral defects seen over a 14-day period.

In conclusion, we developed novel composite bioinks that can be triple-crosslinked, facilitating successful chondrocyte and MSC growth in 3D bioprinted scaffolds and in vitro repair of an osteochondral defect model. This offers hope for a new approach to treating AC defects.

Cheilectomy is a recommended procedure for early stage osteoarthritis of the 1st metatarsophalangeal joint. Although improvement in symptoms has been reported in many studies, long term performance is not well understood. It is thought that significant numbers of patients require subsequent arthrodesis or arthroplasty. We report on a large cohort of patients receiving this procedure and on complications, and mid-term outcome.

This is a retrospective study looking at all patients undergoing cheilectomy for hallux rigidus between November 2007 and August 2018. Departmental database was used to record outcome measures including: postoperative wound infection, patient reported improvement in pain and incidence of further surgical interventions like revision cheilectomy, conversion to arthrodesis and arthroplasty. Osteoarthritis was staged radiographically using PACS (Hattrup and Johnson classification).

A total of 240 feet in 220 patients (20 bilateral surgeries) were included with 164 females (75%) and 56 males (25%), the median age being 55 years (range 22–90 years). Radiological assessment showed 89 stage 1 arthritis (42%), 105 stage 2 (50%), 17 stage 3 (8%) and 9 patients were excluded due to unavailable radiographs. 5 patients (2%) had superficial wound infections. There were 16 further surgeries (7%); 12 arthrodesis (5%), 3 revision cheilectomy and 1 conversion to arthroplasty. 157 patients were found to be pain-free at the latest post-operative visit (77%), 48 reported minimal pain (23%), 15 patients were excluded due to incomplete data.

Cheilectomy appears to effectively reduce pain with low complication rates. Rates of conversion to arthrodesis/arthroplasty are lower than in many reported studies.

The surgical care of extra-articular distal tibial fractures remains controversial. This study looks at the radiological outcomes of distal tibial fractures treated with either a direct medial or anterolateral plate, with or without plating of the fibula, to assess the outcome and complications associated with these 2 approaches.

This is a retrospective review of 80 patients with distal tibial extra-articular fractures, treated with an open reduction and plating, between 2008 and 2019 at Glasgow Royal Infirmary. Case notes and x-rays were reviewed.

Of those tibial fractures fixed with only a medial plate, 78% united (28/36), 5% (2/36) had a non-union and 17% (6/36) a malunion. In the group treated with a combination of medial tibial and fibular plating, the figures were; 71% (15/21), 19% (4/21) and 10% (2/21). However, in the group treated with anterolateral plating of the tibia alone, only 53% (8/15) united, with a 20% (3/15) non-union and 13% (2/15) malunion rate. Additionally in this group, there were 2 patients (13%) with loss of fracture reduction within the first two months of fracture fixation, requiring revision surgery. Interestingly, of the 8 patients treated with anterolateral tibial and fibular plating, 88% (7/8) showed full union and only one (12%) had a non-union, with no malunions is this group.

It would appear that medial tibial and a combination of medial tibial and fibular plating, have superior outcomes compared to anterolateral plating. Results suggest, if anterolateral plating is done, this should be augmented by fixation of the fibular fracture as well.

This study describes the introduction of a virtual pathway for the management of suspected scaphoid fractures and reports patient-reported outcome measures (PROMs) and satisfaction following treatment with this service.

All adult patients that presented with a clinically suspected scaphoid fracture that was not visible on presentation radiographs over a one-year period were eligible for inclusion in the pathway. Demographics, examination findings, clinical scaphoid score (CSS) and standard four view radiographs were collected at presentation. All radiographs were reviewed virtually by a single consultant hand surgeon, with patient-initiated follow-up on request. PROMs were assessed at a minimum of one year post presentation and included the QuickDASH, EQ-5D-5L, the Net Promoter Score (NPS) and return to work.

There were 221 patients referred to the virtual pathway. The mean age was 41 (range 16–87; SD 18.4 years) and there were 99 men (45%). There were 189 (86%) patients discharged with advice and 19 (9%) patients were recalled for clinical review (seven undisplaced scaphoid fractures, six other acute fractures of the hand or wrist, two scapholunate ligament injuries, and four cases where no abnormality was detected). Thirteen patients (6%) initiated follow-up with the hand service; no fracture or ligament injury was identified within this group. PROMs were available for 179 (81%) patients at a mean of 19 months follow-up (range: 13 – 33 months). The median QuickDASH score was 2.3 (IQR, 0–15.9), the median EQ-5D-5L was 0.85 (IQR, 0.73–1.00), the NPS was 76, and 173 (97%) patients were satisfied with their treatment. There were no documented cases of symptomatic non-union one year following injury.

This study reports the introduction of a virtual pathway for suspected scaphoid fractures, demonstrating high levels of patient satisfaction, excellent PROMs, and no detrimental effects in the vast majority of cases.

This study aims to determine the lifetime risk of revision surgery after primary knee arthroplasty (KA).

The Scottish Arthroplasty Project dataset was utilised to identify all patients undergoing primary KA during the period 1998–2019. The cumulative incidence function for revision and death was calculated and adjusted analyses utilised cause-specific Cox regression modelling to determine the influence of patient-factors. The lifetime risk was calculated for patients aged between 45–99 years using multiple decrement lifetable methodology.

The lifetime risk of revision ranged between 32.7% (95% Confidence Interval (CI) 22.62–47.31) for patients aged 45–49 years and 0.63% (95%CI 0.1–4.5) for patients aged over 90 years. Adjusted analyses demonstrated the converse effect of age on revision (Hazard Ratio (HR) 0.5, 95%CI 0.5–0.6) and death (HR 3.5, 95%CI 3.4–3.7). Male sex was associated with increased risks of revision (HR 1.1, 95%CI 1.1–1.2) and death (HR 1.4, 95%CI 1.3–1.4). Patients with inflammatory arthropathy had a higher risk of death (HR 1.7, 95%CI 1.7–1.8), but were less likely to be revised (HR 0.85, 95%CI 0.74–0.98) than those treated for osteoarthritis. Patients with greater number of comorbidities and greater levels of socio-economic deprivation were at increased risk of death, but neither increased the risk of revision.

The lifetime risk of revision knee arthroplasty varies depending on patient sex, age at surgery and underlying diagnosis. Patients aged between 45 and 49 years have a one in three probability of revision surgery within their lifetime. Conversely, patients aged 90 years or over were very unlikely to experience revision.

There is a longstanding presumed association between obesity, complications, and revision surgery in primary knee arthroplasty. This has more recently been called into question, particularly in centres where a high volume of arthroplasty is performed. We investigated the correlation between Body Mass Index (BMI), mortality, and revision surgery.

This was a cohort study of at least 10 years following primary knee arthroplasty from a single high volume arthroplasty unit. Mortality and revision rates were collected from all patients who underwent primary knee arthroplasty between 2009 and 2010. Kaplan Meier analysis was performed.

There were 1161 female and 948 male patients with a mean age of 69 (21 to 97). All cause survivorship excluding mortality was 97.2% up to 13yrs with a minimum of 10 years. The revision rate in this series was 2.8% with no significant difference in revision rates after 10 year between patients with BMI above and below 40 (p=0.438). There was no significant difference in 10–year mortality between patients above and below a BMI of 40 (p=0.238).

This study shows no significant difference in the long term survival of total knee replacement between patients with normal and high BMI. Careful consideration should be given before rationing surgery based on BMI alone.

This study aims to determine satisfaction rates after hip and knee arthroplasty in patients who did not initially respond to PROMs, characteristics of non-responders, and contact preferences to maximise response rates. We performed a prospective cohort study of 709 patients undergoing THA and 737 patients undergoing TKA in a single centre in 2018. EQ-5D health related quality of life score and Oxford Hip/knee scores (OHS/OKS) were completed preoperatively and at 1year postoperatively via post when satisfaction was also assessed. Univariate, multivariate and receiver operator curve analysis were performed.

151/709 (21.2%) hip patients were non-responders, 83 (55.0%) of whom were contactable. 108/737 (14.6%) knee patients were non-responders, 91 (84.3%) of whom were contactable. There was no difference in satisfaction after arthroplasty between initial non-responders and responders for hips (74/81 vs 476/516, p=0.847) or knees (81/93 vs 470/561, p=0.480). Initial and persistent non-response was associated with younger age, higher BMIs and significantly worse preoperative PROMS for both hip and knee patients (p=0.05). Multivariate analysis demonstrated that younger age, higher BMI and poorer pre-operative OHS were independently associated with persistent non-response to hip PROMs (p<0.05). For the entire cohort (n=1352) patients <67 years were less likely to respond to postal PROMs with OR 0.63 (0.558 to 0.711). Using a threshold of >66.4 years predicted a preference for contact by post with 65.4% sensitivity and 68.1% specificity (AUC 0.723 (0.647-0.799 95%CI, p<0.001)).

Most initial non-responders were ultimately contactable with effort. Satisfaction rates were not inferior in patients who did not initially respond to PROMs.

The Poole Traction Splint (PTS) is a non-invasive technique that applies dynamic traction to the affected digit using materials readily available in the outpatient department. The primary aim of this study was to document the outcome of the PTS for hand phalangeal fractures.

Over a four-year period (2017–2021), suitable patients were reviewed and referred for PTS to the hand physiotherapists. Functional outcome measures included range of motion (ROM), return to work, and a DASH score. In addition, a healthcare cost analysis was carried out.

A total of 63 patients were treated with a PTS from 2017 to 2021. Data was analysed for 54 patients with 55 digits. The mean age was 43 years (17–72) and 53.7% (n=29) were female. There were 43 fractures involving the proximal phalanx and 12 involving the middle phalanx. The mean final composite range of movement averaged 209˚ (110–270°), classified as ‘good/excellent’ by ASSH criteria. The mean DASH score was 13.6 (0-43.2; n=45). All patients were able to return to work. Only two (3.7%) digits required conversion to surgical fixation. The PTS resulted in approximate savings of £2,452 per patient.

The PTS is a cost-effective non-invasive low risk outpatient treatment method which provides a functional ROM and good functional outcomes in the treatment of complex phalangeal hand fractures, with minimal risk of surgical intervention being required.

Aims

This study estimated trends in incidence of open fractures and the adherence to clinical standards for open fracture care in England.

Arthrodesis of the 1st metatarsophalangeal joint (MTPJ) is a common procedure used for the treatment of end stage arthritis. We studied a cohort of patients who underwent an isolated 1st MTPJ Fusion for the treatment of hallux rigidus. Here we report the 10-year clinical outcomes, complication rate, requirement for further surgery and patient experience.

All patients, who underwent an isolated 1st MTPJ Fusion for osteoarthritis from June 2008 until November 2011 were included. Demographics, clinical outcome data and subsequent procedures performed were collected from a departmental database (Bluespier). Patients were contacted and asked to complete the MOxFQ questionnaire and rate their satisfaction using pain, function and if they would undergo the surgery again. Mean follow up was 10.85 (range 9–12) years.

A total of 161 patients (183 feet) underwent an isolated 1st MTPJ fusion during this time period. 156 of the feet showed a successful arthrodesis (85.2% fusion rate); 27 patients required revision surgery, 19 (10.4%) for a symptomatic non-union and 8 (4.4%) for mal-union. Those patients with co-morbidities (diabetes and gout) required revision earlier than those without (p<0.01). Average MOxFQ score was 16.6 (0–64) and 28 out of the 38 (73.6%) said they would have the operation again.

Overall, the long-term results of the 1st MTPJ fusion had good outcomes with a successful fusion rate and minimal complications, both in line with the corresponding literature. In this series, fusion provided high patient satisfaction with the majority of patients opting to undergo fusion with the gift of hindsight.

The primary aim was to assess whether patients waiting 6-months or more for a total hip (THA) or knee (KA) arthroplasty had a deterioration in their health-related quality of life (HRQoL). Secondary aims were to assess change in level of frailty and the number living in a state worse than death (WTD).

Eight-six patients waiting for a primary TKA or KA for more than 6-months were selected at random from waiting lists in three centres. Patient demographics, waiting time, EuroQol 5-dimension (EQ-5D) and visual analogue scores (EQ-VAS), Rockwood clinical frailty score (CFS) and SF-36 subjective change in HRQoL were recorded at the time of and for a timepoint 6-months prior to assessment. The study was powered to the EQ-5D (primary measure of HRQoL).

There were 40 male and 46 female patients with a mean age of 68 (33 to 91) years; 65 patients were awaiting a THA and 21 a TKA. The mean waiting time was 372 (226 to 749) days. The EQ-5D index deteriorated by 0.222 (95%CI 0.164 to 0.280, p<0.001). The EQ-VAS also deteriorated by 10.8 (95%CI 7.5 to 14.0, p<0.001). CFS progressed from a median of 3 to 4 (p<0.001). The number of patients WTD increased from seven to 22 (p<0.001). Thirty-one(36%) patients felt their HRQoL was much worse and 28 (33%) felt it was somewhat worse.

Patients waiting more than 6-months had a clinically significant deterioration in their HRQoL and demonstrated increasing level of frailty with more than a quarter living in a health state WTD.

The aim of this study was to identify factors independently associated with symptomatic venous thromboembolism (VTE) following acute Achilles tendon rupture (ATR), and to suggest a clinical VTE risk assessment tool for patients with ATR.

From 2010–2018, 984 consecutive adults (median age 47yrs, 73% male) sustaining an ATR were retrospectively identified. There were 95% managed non-operatively (below-knee cast 52%, n=507/984; walking boot 44%, n=432/984), with 5% (n=45/984) undergoing primary operative repair (<6wks). VTE was diagnosed using medical records and national imaging archives, reviewed at a mean of 5yrs (1–10) post-injury. Regression was performed to identify factors independently associated with VTE.

Incidence of VTE within 90 days of ATR was 3.6% (n=35/984; deep vein thrombosis 2.1% [n=21/984], pulmonary embolism 1.9% [n=19/984]). Age ≥50yrs (adjusted OR [aOR] 2.3, p=0.027), personal history of VTE/thrombophilia (aOR 6.1, p=0.009) and family history of VTE (aOR 20.9, p<0.001) were independently associated with VTE. These non-modifiable risk factors were incorporated into a VTE risk assessment tool. 23% of patients developing VTE (n=8/35) had a relevant personal or family history, but incorporating age into the tool identified 69% of patients with VTE (n=24/35). Non weight-bearing ≥2wks after ATR was also independently associated with VTE (aOR 3.2, p=0.026).

Age ≥50 years, personal history of VTE/thrombophilia and a positive family history were independently associated with VTE following ATR. Incorporating age into our suggested VTE risk assessment tool enhanced sensitivity in identifying at-risk patients. Early weight-bearing in an appropriate orthosis may be beneficial in VTE risk reduction.

Aims

This study aims to estimate economic outcomes associated with 30-day deep surgical site infection (SSI) from closed surgical wounds in patients with lower limb fractures following major trauma.

Aims

There is increasing evidence to support the use of topical antibiotics to prevent surgical site infections. Although previous research suggests a minimal nephrotoxic risk with a single dose of vancomycin powder, fracture patients often require multiple procedures and receive additional doses of topical antibiotics. We aimed to determine if cumulative doses of intrawound vancomycin or tobramycin powder for infection prophylaxis increased the risk of drug-induced acute kidney injury (AKI) among fracture patients.

Aims

The primary aim of this study was to determine the rates of return to work (RTW) and sport (RTS) following a humeral shaft fracture. The secondary aim was to identify factors independently associated with failure to RTW or RTS.

Aims

To evaluate the impact of negative pressure wound therapy (NPWT) on the odds of having deep infections and health-related quality of life (HRQoL) following open fractures.

Aims

Our objective was to conduct a systematic review and meta-analysis, to establish whether differences arise in clinical outcomes between autologous and synthetic bone grafts in the operative management of tibial plateau fractures.

Aims

Postoperative malalignment of the femur is one of the main complications in distal femur fractures. Few papers have investigated the impact of intraoperative malalignment on postoperative function and bone healing outcomes. The aim of this study was to investigate how intraoperative fracture malalignment affects postoperative bone healing and functional outcomes.

Aims

The purpose was to compare operative treatment with a volar plate and nonoperative treatment of displaced distal radius fractures in patients aged 65 years and over in a cost-effectiveness analysis.

Aims

Deep surgical site infection (SSI) remains an unsolved problem after hip fracture. Debridement, antibiotic, and implant retention (DAIR) has become a mainstream treatment in elective periprosthetic joint infection; however, evidence for DAIR after infected hip hemiarthroplaty is limited.

Aims

The study objective was to prospectively assess clinical outcomes for a pilot cohort of tibial shaft fractures treated with a new tibial nailing system that produces controlled axial interfragmentary micromotion. The hypothesis was that axial micromotion enhances fracture healing compared to static interlocking.

Global surgical literature suggests that female trainees have less operative autonomy than their male counterparts. This pilot study had the primary objective to identify difference in autonomy by gender, and to power a national study to carry out further quantitative and qualitative research on this.

This was a retrospective, cross-sectional study utilising eLogbook data for all orthopaedic trainees (ST2-8) and consultants with CCT date 2016–2021 in a single Scottish deanery. The primary outcome measure was percentage of procedures undertaken as lead surgeon. 15 trainees and four recent consultants participated, of which 12 (63%) were male (mean grade 5.2), and 7 (37%) were female (mean grade 4.3). Trainees were lead surgeon on 64% of procedures (17595/27558), with autonomy rising with grade (37% ST1 to 85% ST8, OR 9.4). Operative autonomy was higher in male vs female trainees (66.5% and 61.4% respectively, p=<0.0001), with female trainees more likely to operate with a supervisor present (STU/S vs P/T, f 48%:13%, m 45%:20%).

This pilot study found that there was a significant difference in operative autonomy between male and female trainees, however this may be explained by differences in mean grade of male vs female trainees. Five trainees took time OOT, 4/5 of whom were female. Extension to a national multi-centre study should repeat the quantitative method of this study with additional qualitative analysis including assessing effect of time OOT to explore the reason for any gender discrepancies seen across different deaneries in the UK.

Reconfiguration of elective orthopaedic surgery presents challenges and opportunities to develop outpatient pathways to reduce surgical waiting times. Dupuytren's disease (DD) is a benign progressive fibroproliferative disorder of the fascia in the hand, which can be disabling. Percutaneous-needle-fasciotomy (PNF) can be performed successfully in the outpatient clinic.

The Aberdeen hand-service has over 10 years' experience running dedicated PNF clinics. NHS Grampian covers a vast area of Scotland receiving over 11749 referrals to the orthopaedic unit yearly. 250 patients undergone PNF in the outpatient department annually. 100 patients who underwent PNF in outpatients (Jan2019–Jan2020).

79M, 21F. Average age 66 years range (29–87). 95 patients were right hand dominant. DD risk factors: 6 patients were diabetic, 2 epileptic, 87 patients drank alcohol. 76 patients had a family history of DD. Disease severity, single digit 20 patients, one hand multiple digits in 15 patients, bilateral hands in 65 patients of which 5 suffered form ectopic manifestation suggestive of Dupuytren's diasthesis. Using Tubiana Total flexion deformity score pre and post fasciotomy. Type 1 total flexion deformity (TFD) between 0–45 degrees pre PNF n=60 post N= 85, Type 2 TFD 45–90 degrees pre PNF n=18 post N=9, Type 3 TFD 90–135 pre PNF n=15 post N= 5, Type 4 TFD >135 pre PNF n=1 post PNF N=1. Using Chi-square statistical test, a significant difference was found at the p<0.05 between the pre and post PNF TFD. Complication: 8 recurrence, 1 skin tear. No patients sustained digital nerve injury.

Outpatients PNF clinics are a valuable resource.

Prophylactic pinning of the contralateral hip in unilateral Slipped Upper Femoral Epiphysis (SUFE) persists as a source of debate with the majority of surgeons selecting this option in a proportion of patients whom they regard as at increased risk of a subsequent slip.

Universal prophylactic pinning was introduced in our region in 2005 after an audit of ten years local practice identified 25% of unilateral cases presented with a subsequent slip. This study reports our experience between 2005 and 2020.

In this prospective study, 44 patients presented with 55 affected hips compared with 60 patients with 67 affected hips in the original study. Two patients were excluded as their initial slip had not been treated in our unit. Of the 42 hips seven were bilateral, 34 of the 35 unilateral hips underwent prophylactic pinning. The one exception subsequently underwent prophylactic pinning due to developing pain.

Consistent with our original series, at a minimum follow up of 13 months there have been no complications of infection, fracture, chondrolysis or avascular necrosis subsequent to prophylactic pinning.

Over 25 years 70 patients have undergone prophylactic pinning without complication. On the premise that 25% of our unpinned hips presented with subsequent slips before instituting our policy we estimate that we have prevented 17 subsequent slips over 25 years including the consequences which can be significant. We continue to advocate universal prophylactic pinning as an effective and safe practice in the management of SUFE.

Unicompartmental knee osteoarthritis can be treated with either Total Knee Arthroplasty (TKA) or Unicompartmental Knee Arthroplasty (UKA) and controversy remains as to which treatment is best. UKA has been reported to offer a variety of advantages, however many still see it as a temporary procedure with higher revision rates.

We aimed to clarify the role of UKA and evaluate the long-term and revision outcomes. We retrospectively reviewed the pain, function and total Knee Society Score (KSS) for 602 UKA and 602 TKA in age and gender matched patients over ten years.

The total pre-operative KSS scores were not significantly different between UKA and TKA (42.67 vs 40.54 P=0.021). KSS (pain) was significantly better in the TKA group (44.39 vs 41.38 P= 0.007) at one year and at five years post-operatively (45.33 vs 43.12 P=0.004). There was no statistically significant difference for KSS (total) in TKA and UKA during the study period. 16.3% of UKA and 20.1% of TKA had a documented complication. 79 UKA (13%) and 36 TKA (6%) required revision surgery. Despite the higher revision rate, pre-operative KSS (total) before revision was not significantly different between UKA and TKA (42.94 vs 42.43 P=0.84). Performance for UKAs was inferior to TKAs in Kaplan-Meier cumulative survival analysis at 10 years (P<0.001).

Both UKA and TKA are viable treatment options for unicompartmental knee osteoarthritis, each with their own merits. UKA is associated with fewer complications whereas TKA provides better initial pain relief and is more durable and less likely to require revision.

This international multicentre retrospective cohort study aimed to assess: 1) prevalence of COVID-19 in hip fracture patients, 2) effect on mortality, and 3) clinical factors associated mortality among COVID-19-positive patients.

A collaboration among 112 centres in 14 nations collected data on all patients with a hip fracture between 1st March-31st May 2020. Patient, injury and surgical factors were recorded, and outcome measures included admission duration, COVID-19 and 30-day mortality status.

There were 7090 patients and 651 (9.2%) were COVID-19-positive. COVID-19 was independently associated with male sex (p=0.001), residential care (p<0.001), inpatient fall (p=0.003), cancer (p=0.009), ASA grade 4–5 (p=0.008; p<0.001), and longer admission (p<0.001). Patients with COVID-19 had a significantly lower chance of 30-day survival versus those without (72.7% versus 92.6%, p<0.001), and COVID-19 was independently associated with increased 30-day mortality risk (p<0.001). Increasing age (p=0.028), male sex (p<0.001), renal (p=0.017) and pulmonary disease (p=0·039) were independently associated with higher 30-day mortality risk in patients with COVID-19 when adjusting for confounders.

The prevalence of COVID-19 in hip fracture patients was 9% and was independently associated with a three-fold increased 30-day mortality risk. Clinical factors associated with mortality among COVID-19-positive hip fracture patients were identified for the first time. This is the largest study, and the only global cohort, reporting on the effect of COVID-19 in hip fracture patients. The findings provide a benchmark against which to determine vaccine efficacy in this vulnerable population and are especially important in the context of incomplete vaccination programmes and the emergence of vaccine-resistant strains.

Management of highly displaced acromioclavicular joint (ACJ) injuries remain contentious. It is unclear if delayed versus acute reconstruction has an increased risk of fixation failure and complications. The primary aim of this was to compare complications of early versus delayed reconstruction. The secondary aim was to determine modes of failure of ACJ reconstruction requiring revision surgery.

A retrospective study was performed of all patients who underwent operative reconstruction of ACJ injuries over a 10-year period (Rockwood III-V). Reconstruction was classed as early (<12 weeks from injury) or delayed (≥12 weeks). Patient demographics, fixation method and post-operative complications were noted, with one-year follow-up a minimum requirement for inclusion. Fixation failure was defined as loss of reduction requiring revision surgery.

104 patients were analysed (n=60 early and n=44 delayed). Mean age was 42.0 (SD 11.2, 17–70 years), 84.6% male and 16/104 were smokers. No difference was observed between fixation failure (p=0.39) or deep infection (p=0.13) with regards to acute versus delayed reconstruction. No patient demographic or timing of surgery was predictive of fixation failure on regression modelling. Overall, eleven patients underwent revision surgery for loss of reduction and implant failure (n=5 suture fatigue, n=2 endo-button escape, n=2 coracoid stress fracture and n=2 deep infection).

This study suggests that delayed ACJ reconstruction does not have a higher incidence of fixation failure or major complications compared to acute reconstruction. For those patients with ongoing pain and instability following a trial of non-operative treatment, delayed reconstruction would appear to be a safe treatment approach.

Aims

The modified Radiological Union Scale for Tibia (mRUST) fractures score was developed in order to assess progress to union and define a numerical assessment of fracture healing of metadiaphyseal fractures. This score has been shown to be valuable in predicting radiological union; however, there is no information on the sensitivity, specificity, and accuracy of this index for various cut-off scores. The aim of this study is to evaluate sensitivity, specificity, accuracy, and cut-off points of the mRUST score for the diagnosis of metadiaphyseal fractures healing.

One potential approach to addressing the current hip and knee arthroplasty backlog is via adoption of surgical prioritisation methods, such as use of pre-operative health related quality of life (HRQOL) assessment. We set out to determine whether dichotomization using a previously identified bimodal EuroQol Five-Dimension (EQ-5D) distribution could be used to triage waiting lists.

516 patients had data collected regarding demographics, perioperative variables and patient reported outcome measures (pre-operative & 1-year post-operative EQ-5D-3L and Oxford Hip and Knee Scores (OHS/OKS). Patients were split into two equal groups based on pre-operative EQ-5D Time Trade-Off (TTO) scores and compared (Group1 [worse HRQOL] = −0.239 to 0.487; Group2 [better HRQOL] = 0.516 to 1 (best)). The EQ5D TTO is a widely used and validated HRQOL measure that generates single values for different combinations of health-states based upon how individuals compare x years of healthy living to x years of illness.

We identified that those in Group1 had significantly greater improvement in post-operative EQ-5D TTO scores compared to Group2 (Median 0.67vs.0.19; p<0.0001 respectively), as well as greater improvement in OHS/OKS (Mean 22.4vs16.4; p<0.0001 respectively). Those in Group2 were significantly less likely to achieve EQ-5D MCID attainment (OR 0.13, 95%CI 0.07–0.23; p<0.0001) with a trend towards lower OHS/OKS MCID attainment (OR 0.66, 95%CI 0.37–1.19; p=0.168). There was no statistically significant difference in adverse events.

These finding suggest that a pre-operative EQ-5D cut-off of ≤0.487 for hip and knee arthroplasty prioritisation may help to maximise clinical utility and cost-effectiveness in a limited resource setting post COVID-19.

Success treating AIS with bracing is related to time worn and scoliosis severity. Temperature monitoring can help patients comply with their orthotic prescription. Routinely collected temperature data from the start of first brace treatment was reviewed for 14 patients. All were female with an average age of 12.4 years (range 10.3–14.6) and average 49o Cobb angle (30–64).

Our current service recommendation is brace wear for 20 hours a day. Patients complied with this prescription 38.0% of the time, with four patients averaging this or more. Average brace wear was 16.3 hours per day (3.5–22.2).

There were 13 patients who had completed brace treatment. The majority had surgery (7/13; 54%) or were considering surgery (1/13; 8%). There were 5 who did not wish surgery at discharge (5/13; 38%); 1 achieved a 40o Cobb angle, with 4 larger (53o;53o;54o;68o). The Bracing in AIS Trial (BrAIST) study measured “success” as less than a 50o Cobb angle, so using this metric our cohort has had a single “success”.

Temperature monitors allowed an analysis of when patients were achieving their brace wear. When comparing daywear (8am-8pm) to nightwear (8pm-8am), patients wore their brace an average of 7.6 hours a day (2.5–11.2) and 8.7 hours a night (0.4–11.5).

We conclude the minority of our patients comply with our current 20 hour orthotic prescription. The “success” of brace treatment is lower than comparison studies despite higher average compliance but starting with a larger scoliosis. Brace wear is achieved during both the day and night.

The Olympia femoral stem is a stainless steel, anatomically shaped, polished and three-dimensionally tapered implant designed for use in cemented total hip arthroplasty (THA). The primary aim of this study was to determine the long-term survivorship, radiographic outcome, and patient reported outcome measures (PROMs) of the Olympia stem.

Between May 2003 and December 2005, 239 patients (264 THAs) underwent a THA with an Olympia stem in our institution. PROMs were assessed using the Oxford Hip Score (OHS), EuroQol-5 dimensions (EQ-5D) score and patient satisfaction at mean 10-years following THA. Patient records and radiographs were then reviewed at a mean of 16.5 years (SD 0.7, 15.3 to 17.8) following THA to identify occurrence of complications or revision surgery for any cause.

Mean patient age at surgery was 68.0 years (SD 10.9, 31–93 years). There were 156 women (65%, 176 THAs). Osteoarthritis was the indication for THA in 204 patients (85%). Stem survivorship at 10 years was 99.2% (95 % confidence interval [CI], 97.9%-100%) and at 15 years was 97.5% (94.6%–100%). The 15-year stem survival for aseptic loosening was 100%. Only one occurrence of peri-prosthetic fracture was identified, with no episodes of dislocation found. At a mean of 10 (SD 0.8, 8.7 –11.3) years follow-up, mean OHS was 39 (SD 10.3, range 7 – 48) and 94% of patients reported being very satisfied or satisfied.

The Olympia stem demonstrated excellent 10-year PROMs, very high rates of stem survivorship and negligible peri-prosthetic fracture and dislocation rate at final follow-up beyond 15 years.

The primary aim was to determine the rate of complications and re-intervention rate in a consecutive series of operatively managed distal radius fractures.

Data was retrospectively collected on 304 adult distal radius fractures treated at our institution in a year. Acute unstable displaced distal radius fractures surgically managed within 28 days of injury were included. Demographic and injury data, as well as details of complications and their subsequent management were recorded.

There were 304 fractures in 297 patients. The mean age was 57yrs and 74% were female. Most patients were managed with open reduction and internal fixation (ORIF) (n=278, 91%), with 6% (n=17) managed with manipulation and Kirschner wires and 3% (n=9) with bridging external fixation. Twenty-seven percent (n=81) encountered a post-operative complication. Complex regional pain syndrome was most common (5%, n=14), followed by loss of reduction (4%). Ten patients (3%) had a superficial wound infection managed with oral antibiotics. Deep infection occurred in one patient. Fourteen percent (n=42) required re-operation. The most common indication was removal of metalwork (n=27), followed by carpal tunnel decompression (n=4) and revision ORIF (n=4). Increasing age (p=0.02), male gender (p=0.02) and high energy mechanism of injury (p<0.001) were associated with developing a complication. High energy mechanism was the only factor associated with re-operation (p<0.001).

This study has documented the complication and re-intervention rates following distal radius fracture fixation. Given the increased risk of complications and the positive outcomes reported in the literature, non-operative management of displaced fractures should be considered in older patients.

Despite multiple published reviews, the optimum method of correction and stabilisation of Blount's disease remains controversial. The purpose of this study is to evaluate the clinical and radiological outcomes of acute correction of late-onset tibial vara by percutaneous proximal tibial osteotomy with circular external fixation using two simple rings. This technique was developed to minimise cost in a context of limited resources.

This study was conducted between 2016 and 2020. We retrospectively reviewed the clinical notes and radiographs of 30 patients (32tibiae) who had correction of late-onset tibia by proximal tibial osteotomy and Ilizarov external fixator. All cases were followed up to 2 years.

The mean proximal tibial angle was 65.7° (±7.8) preoperatively and 89.8° (±1.7) postoperatively. The mean mechanical axis deviation improved from 56.2 (±8.3) preoperatively to 2.8 (±1.6) mm postoperatively. The mean femoral-tibial shaft angle was changed from – 34.3° (±6.7) preoperatively to 5.7° (±2.8) after correction. Complications included overcorrection (9%) and pin tract infection (25%). At final follow up, all patients had full knee range of motion and normal function. All cases progressed to union and there were no cases of recurrence of deformity.

This simple procedure provides secure fixation allowing early weight bearing and early return to function. It can be used in the context of health care systems with limited resources. It has a relatively low complication rate. Our results suggest that acute correction and simple circular frame fixation is an excellent treatment choice for cases of late-onset tibia vara, especially in severe deformities.

Aims

The aims of this network meta-analysis (NMA) were to examine nonunion rates and functional outcomes following various operative and nonoperative treatments for displaced mid-shaft clavicle fractures.

Aims

It is unclear whether acute plate fixation facilitates earlier return of normal shoulder function following a displaced mid-shaft clavicular fracture compared with nonoperative management when union occurs. The primary aim of this study was to establish whether acute plate fixation was associated with a greater return of normal shoulder function when compared with nonoperative management in patients who unite their fractures. The secondary aim was to investigate whether there were identifiable predictors associated with return of normal shoulder function in patients who achieve union with nonoperative management.

Aims

To explore staff experiences of a multicentre pilot randomized controlled trial (RCT) comparing intramedullary nails and circular frame external fixation for segmental tibial fractures.

Aims

The aim of this study to compare 30-day survival and recovery of mobility between patients mobilized early (on the day of, or day after surgery for a hip fracture) and patients mobilized late (two days or more after surgery), and to determine whether the presence of dementia influences the association between the timing of mobilization, 30-day survival, and recovery.

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.

The aim of this study was to define the long-term outcome following adolescent clavicle fracture.

We retrospectively reviewed all adolescent fractures presenting to our region (13–17years) over a 10-year period. Patient reported outcomes were undertaken at a minimum of 4 years post-injury (QuickDASH and EQ-5D) in completely displaced midshaft fractures (Edinburgh 2B, >2cm displacement, n=50) and angulated midshaft fractures (Edinburgh 2A2, >30 degrees angulation, n=32).

677 clavicle fractures were analysed. The median age was 14.8 (IQR 14.0–15.7) and 89% were male. The majority were midshaft (n=606, 89.5%) with either angulation (39.8%) or simple fully displaced (39.1%). Only 3% of midshaft fractures underwent acute fixation (n=18/606), all of which were fully displaced. The incidence of refracture following non-operative management of midshaft fractures was 3.2% (n=19/588), all united with non-operative management. Fracture type, severity of angulation or displacement was not associated with risk of refracture. There was one case of non-union encountered following non-operative management of all displaced midshaft fractures (0.4%, n=1/245). At a mean of 7.6 years following injury, non-operative management of both displaced and angulated fractures had a median QuickDASH was 0.0 (IQR 0.0–2.3), EQ-5D was 1.0 (IQR 1.0–1.0). 97% of angulated fractures and 94% of displaced fractures were satisfied with their final shoulder function.

We conclude that Non-operative management of adolescent midshaft clavicle fractures result in excellent functional outcomes with a low rate of complications at long-term follow up. The relative indications for surgical intervention for clavicle fractures in adults do not appear to be applicable to adolescents.

Open reduction and internal fixation (ORIF) with trans-articular screws or dorsal plating is the standard surgical technique for displaced Lisfranc injuries. This aim of this study is to compare the clinical outcomes of percutaneous reduction and internal fixation (PRIF) of low energy Lisfranc injuries with a matched, control group of patients treated with ORIF.

Over a seven-year period (2012–2019), 16 consecutive patients with a low energy Myerson B2-type injury were treated with PRIF. Patient demographics were recorded within a prospectively maintained database at the institution. This study sample was matched for age, sex and mechanism of injury to a control group of 16 patients with similar Myerson B2-type injuries treated with ORIF. Clinical outcome was compared using the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and Manchester Oxford Foot Questionnaire (MOXFQ).

At a mean follow up of 43.0 months (95% CI 35.6 – 50.4), both the AOFAS and MOXFQ scores were significantly higher in the PRIF group compared to the control ORIF group (AOFAS 89.1vs 76.4, p=0.03; MOXFQ 10.0 vs 27.6, p=0.03). There were no immediate postoperative complications in either group. At final follow up, there was no radiological evidence of midfoot osteoarthritis in any patient in the PRIF group. Three patients in the ORIF group developed midfoot osteoarthritis, one of whom required midfoot fusion.

PRIF is a technically simple, less invasive method of operative stabilisation of low energy Lisfranc injures which also appears to be associated with better mid-term clinical outcomes compared to ORIF.

Non-surgical osteoarthritis management includes analgesia escalation to oral opiates; however, tolerance can occur. This study aims to assess analgesic effects of opiate use pre-operatively and whether this influences outcome 1-year post-operatively in patients undergoing total hip/knee arthroplasty (THA/TKA).

This prospective study assessed 1487 patients undergoing primary THA (n=729) or TKA (n=758) for osteoarthritis, with 95 respectively reporting pre-operative opiate use >1 month. THA opiate users had significantly higher BMI (p=0.007) and more likely to suffer associated comorbidities. TKA opiate users were significantly younger (p<0.001), with higher BMI (p=0.019) and more likely to suffer associated comorbidities. Pre-operative quality of life (QoL) and joint specific function were significantly worse (Hip EQ-5D 0.17 vs 0.41, p<0.001, OHS 14.6 vs 21.2, p<0.001; Knee EQ-5D 0.27 vs 0.44, p<0.001, OKS 16.4 vs 21.4, p<0.001). Pre-operative pain was significantly worse in those taking opioids (Hip Pain VAS 42.73 vs 50.70, p<0.001; Knee Pain VAS 50.93 vs 53.36, p=0.30). Post-operatively the THA opiate group had significant improvement in EQ-5D (0.175, p<0.001) and OHS (6.5, p<0.001) but were significantly less improved than opiate naïve patients after adjusting for confounding (EQ-5D 0.10, p<0.001; OHS 3.2, p<0.001). TKA opiate group also had significant improvement in EQ-5D (p<0.001) and OKS (p<0.001) but were significantly less (EQ-5D 0.089, p<0.001; OKS 3.9, p<0.001) than opioid naïve patients.

Pre-operative opiate use was associated with significantly worse pre-operative QoL, joint specific function and worse subjective pain. Post-operatively, the opiate group had significantly lower improvement in their QoL and joint specific function.

The aim of this study was to determine if the extent of the glenoid and humeral bone loss affects the rate of recurrent instability and the functional outcome following the Latarjet procedure.

161 patients underwent open Latarjet procedure during the period 2006–2015 (Mean age 30.0 years, 150t (93.2%) Male, 118 (73.3%) primary procedure). Functional outcome was measured using the Western Ontario Shoulder Instability Index (WOSI) and Quick Disabilities of the Arm, Shoulder and Hand (QuickDash) score at a mean of 4.7 years post-operatively. All patients underwent computed tomographic (CT) imaging pre-operatively. Using three-dimensional reconstruction, the glenoid bone loss, Hill-Sachs lesion and ‘Glenoid Track’ status was recorded.

Radiographically-confirmed redislocation was rare (1.2%), but 18.5% (n=23/124) reported ongoing subjective shoulder instability. Fifty-two shoulders (32.3%) were classified as “Off-Track”. The median Quick DASH and WOSI scores were 2.27 (IQR 9.09; range 0–70.45) and 272.0 (IQR 546.5; range 0–2003), respectively. There were no significant differences observed between overall Quick DASH scores or WOSI scores for either On-Track or Off-Track groups (p=0.7 and 0.73, respectively). Subjective instability was not influenced by the degree of glenoid bone loss (p=0.82), the overall size of the Hill-Sachs lesion (p=0.80), or the presence of an ‘Off-Track’ lesion (p=0.84).

Functional outcome and recurrent instability following the Latarjet procedure do not appear to be influenced by the extent of glenohumeral bone loss prior to surgery.

Brachial plexus tumours (BPT) and peripheral nerve sheath tumours (PNST) are largely benign in nature, with malignant tumours being rare and presenting significant surgical challenges. Excision of benign tumours may relieve pain and other symptomology. This retrospective study analysed data from 138 PNST and 92 BPT patients managed by a single consultant orthopaedic or plastic surgeon experienced in nerve tumour surgery between January 1999 to December 2019. The most common benign tumours were schwannomas and neurofibromas, with sarcomas being the most common malignant tumour.

In the PNST group 30 patients were managed by observation only. Twenty patients underwent trucut biopsy, 21 patients underwent biopsy and surgical excision and 56 patients underwent surgical excision only. There were nine complications, with two significant neurological deficits requiring further surgical intervention. No recurrence of tumours occurred in this group.

In the BPT group 16 patients were managed by observation only. Seven patients underwent trucut biopsy, 16 patients biopsy and surgical excision and 44 BPT patients underwent surgical excision only. Sixteen patients had complications with two significant complications requiring urgent further surgical intervention. Seven patients had recurrence of tumours which presented as metastases, with three patients requiring further surgery to remove recurrence of tumours.

BPT patients are more complex and present with both benign and malignant lesions and are therefore more prone to complications due to the complex nature of the surgery and higher recurrence rate of tumours than PNST. Benign tumours in both groups can be safely managed conservatively if patients’ symptomology is acceptable.

The aim was to report operative complications, radiographic and patient-reported outcomes following lateral tibial plateau fracture fixation augmented with calcium phosphate cement (CPC).

From 2007–2018, 187 patients (median age 57yrs [range 22–88], 63% female [n=118/187]) with a Schatzker II/III fracture were retrospectively identified. There were 103 (55%) ORIF and 84 (45%) percutaneous fixation procedures. Complications and radiographic outcomes were determined from outpatient records and radiographs. Long-term follow-up was via telephone interview.

At a median of 6 months (range 0.1–138) postoperatively, complications included superficial peroneal nerve injury (0.5%, n=1/187), infection (6.4%, n=12/187), prominent metalwork (10.2%, n=19/187) and post-traumatic osteoarthritis (PTOA; 5.3%, n=10/187). The median postoperative medial proximal tibial angle was 89o (range 82–107) and posterior proximal tibial angle 82o (range 45–95). Three patients (1.6%) underwent debridement for infection and 27 (14.4%) required metalwork removal. Seven patients (4.2%) underwent total knee replacement for PTOA.

Sixty percent of available patients (n=97/163) completed telephone follow-up at a median of 6yrs (range 1–13). The median Oxford Knee Score was 42 (range 3–48), Knee injury and Osteoarthritis Outcome Score 88 (range 10–100), EuroQol 5-Dimension score 0.812 (range −0.349–1.000) and Visual Analogue Scale 75 (range 10–100). There were no significant differences between ORIF and percutaneous fixation in patient-reported outcome (all p>0.05).

Fixation augmented with CPC is safe and effective for lateral tibial plateau fractures, with a low complication rate and good long-term knee function and health-related quality of life. Percutaneous fixation offers a viable alternative to ORIF with no detriment to patient-reported outcome.

Non-operative management of displaced olecranon fractures in elderly low demand patients is reported to result in a satisfactory outcome despite routinely producing a nonunion. The aim of this study was to assess whether there is evidence of dynamic movement of the fracture fragment during the elbow arc of movement.

Five consecutive patients (≥70 years of age) with a displaced olecranon fracture (Mayo 2A) that were managed with non-operative intervention were recruited. All underwent ultrasound evaluation at six weeks and follow-up questionnaires at six months including the DASH and Oxford Elbow Score (OES).

There were three women and two men with a mean age of 79yrs (range 70–88). All injuries were sustained following a fall from standing height. The mean fracture gap in extension was 22.5mm (95% CI 13.0–31.9), midflexion 21.8mm (11.6–32.0) and in deep flexion 21.8mm (10.9–32.8). Although the amount of fracture displacement varied between patients, it remained static in each patient with no significant differences observed throughout the arc of motion (ANOVA p=0.99). The six-month median DASH score was 7.5 (IQR range, 4.2–39.3) and the OES was 44.0 (29.0–47.5). Four out of the five patients were satisfied with their function.

Ultrasound evaluation of displaced olecranon fractures following non-operative management suggests the proximal fragment may function as a sesamoid type bone within the triceps sleeve. This could explain how a functional arc of movement with a minimum level of discomfort can usually be expected with non-operative management in select patients.

The purpose of this study is the evaluate the net promotor score of arthroscopic subacromial decompression and rotator cuff repair.

The Friends and Family Test, a variant of the Net Promoter Score, was adapted for the National Health Service to evaluate overall patient satisfaction and how likely patients are to recommend an intervention. It ranges from −100 to 100. Positive scores indicate good performance.

This study quantifies the scores in 71 patients at 1 year following arthroscopic sub acromial decompression and rotator cuff repair. All of the procedures were performed by 1 consultant shoulder specialist. The patient filled out a shoulder questionnaire pre-operatively, at 6 months and 1 year.

The score was 72 for subacromial decompression (n = 32) and 85 for rotator cuff repair +/− decompression (n = 39). Oxford shoulder score was also taken and had a rise of 4.3 and 6.9 respectively. Our study indicates that these procedures are highly valued and are recommended by patients according to the Friends and Family Test. The results of the Friends and Family Test correlated well with postoperative functional improvement and satisfaction.

We conclude from this study that a compound score based on the Friends and Family Test is a useful addition to traditional measures of patient satisfaction.
