Introduction. The optimal treatment of elderly patients with unstable ankle fractures is a widely contested and as yet unresolved issue. Whereas the AO technique of anatomical reduction and plate fixation has been shown to give good functional results it is associated with a wound complication rate of up to 40%. This has led some surgeons to believe the risks of operative intervention are too great. The fibula nail is an intra-medullary device with the benefit of requiring minimal soft-tissue dissection. It provides lateral column support over a greater area than the standard plate. The study aims were to assess the clinical and radiographic outcome of a cohort of patients managed with the Fibula Nail (Acumed). Methods. A prospectively collected group of 36 patients with an unstable Weber B or C fracture were managed with a fibula nail. Outcome measures at one-year follow-up were Olerud and Molander ankle scores, radiographic measurements and complications. Results. At one-year follow-up the average Olerud and Molander score was 89/100. Four patients had died and none were lost to follow-up. Twenty-nine patients had normal radiographic measurements, one required a fusion due to fixation failure and two had signs of osteoarthritis. There were two lateral wound infections which both settled without metal work removal. Conclusions. Our case series has demonstrated similar one-year clinical and radiographical results for the fibular nail as previously published with the standard plate and screw technique with few wound complications. The results do indicate the fibula nail has a role in the management of this notoriously difficult fracture. Whether this cohort continues to do well however is unknown and will be the focus of future research

Introduction

Chronic ankle instability is a common condition that can be effectively treated with arthroscopic lateral ankle ligament reconstruction to restore ankle stability and function. The aim of this study was to assess the functional outcomes of arthroscopic lateral ligament reconstruction using the MOXFQ, VAS, and EQ5D patient-reported outcome measures (PROMs).

Methods

This prospective series included 38 patients who underwent arthroscopic lateral ligament reconstruction for chronic ankle instability between December 2019 and April 2022. All patients completed the MOXFQ, VAS, and EQ5D PROMs preoperatively, as well as at6, and 12 months postoperatively. The MOXFQ is a disease-specific PROM that assesses foot and ankle function, while the VAS measures pain and the EQ5D evaluates health-related quality of life.

Background:

Leg length discrepancy related to absence of the femoral head with proximal migration of the femur presents a treatment dilemma. Late sequelae of neonatal hip sepsis and chronic hip dislocation due to developmental dysplasia are the most common causes. Traditional teaching dictates that the hip is stabilised prior to limb lengthening. Reconstructive options alter the shape of the proximal femur which complicates future surgery.

Methods:

We retrospectively reviewed 3 cases of femoral lengthening with an ‘unstable’ hip without prior stabilization. The aetiology was neonatal hip sepsis in 2 cases and chronic hip dislocation due to developmental dysplasia in 1 case. Lengthening was performed with the use of a retrograde Precice lengthening nail.

Hand fasciotomy is a rarely performed procedure which should be considered by military surgeons, and performed where necessary. Maximising hand function is vital in all military patients, but is even more significant in those who have lost multiple limbs and require maximal function from remaining hands, which are commonly injured too. It is vital that compartments are decompressed expediently to minimize muscle ischaemia.

Cases were identified from the JTTR from March 2003. Data were collected prospectively from Aug 2009 to Feb 2010. Patient notes were analysed and the following recorded –demographics, mechanism of injury (MOI), associated injuries, echelon of care at which fasciotomy was performed, indication recorded by operating surgeon, and specialty of operating surgeon.

9 patients were identified, median age was 23, MOI was IED in 8/9 and mine in 1/9/. All were multiply injured. 4/9 (44%) were performed at R3 and 5/9 (56%) at R4. All fasciotomies at R4 were performed at the first debridement, intrinsic muscles were found to be necrotic in 1 case. At R3 3/4 were performed by orthopaedic surgeons and 1/4 by a plastic surgeon, at R4 all were performed by hand surgeons, either orthopaedic or plastic.

All fasciotomies performed at R4 were at the first debridement, and 1 revealed necrotic intrinsic muscles. This implies that some of these patients may have benefited from earlier procedures. In upper limb injury where it is not possible to passively flex the metacarpophalangeal joints to 90 degrees, decompressing the hand should be considered.

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.

Aim

Circular frames are used to treat a wide spectrum of acute injuries and deformities. We report on our experience of treating both acute and chronic trimalleolar fracture dislocations with a closed technique, utilizing fine wires and a circular frame.

Methods

Data was collected from all patients treated for either acute or chronic trimalleolar fracture dislocations at a single centre between January 2016 and December 2017. A total of 10 patients were identified, 8 with acute injuries and 2 with chronic/delayed injuries. Clinical and radiological outcomes were recorded, as well as patient reported outcome measures (PROMs) using the Chertsey Outcome Score for Trauma (COST score).

We present (with intra-operative imaging) 4 patients who sustained Pectoralis major ruptures on the same piece of equipment of the “Tarzan” assault course at the Commando Training Centre, Royal Marines (CTCRM). Recruits jump at running pace, carrying 21 pounds of equipment and a weapon (8 pounds) across a 6ft gap onto a vertical cargo-net. The recruits punch horizontally through the net, before adducting their arm to catch themselves, and all weight, on their axilla.

All patients presented with immediate pain and reduced function. 2 had ruptures demonstrated on MRI, 1 on USS and one via clinical examination. All 4 patients were found, at operation, to have sustained type IIIE injuries.

All patients underwent Pectoralis major repair using a uni-cortical button fixation and had an uneventful immediate post operative course. Patient 1 left Royal Marines training after the injury (out of choice, not because of failure to rehabilitate). All other patients are under active rehabilitation hoping to return to training.

Review of 10 years of records at CTCRM reveal no documented Pectoralis major rupture prior to our first case in October 2013. There has been no change to the obstacle or technique used and all patients deny the use of steroids.

Changes in armour reinforcement of military vehicles have resulted in a changed injury pattern. Injuries which would previously have resulted in amputation are now less severe, and after initial debridement and temporary fixation the foot can now be saved. New patterns of injuries are emerging often as a part of potentially survivable poly-trauma. We describe a small series of these injuries. The techniques and results of late reconstruction are presented. We also discuss specific problems of managing patients with potential contamination with unusual organisms.

Over a five-year period, adult patients with marginal impaction of acetabular fractures were identified from a registry of patients who underwent acetabular reconstruction in two tertiary referral centres. Fractures were classified according to the system of Judet and Letournel. A topographic classification to describe the extent of articular impaction was used, dividing the joint surface into superior, middle and inferior thirds. Demographic information, hospitalisation and surgery-related complications, functional (EuroQol 5-D) and radiological outcome according to Matta’s criteria were recorded and analysed. In all, 60 patients (57 men, three women) with a mean age of 41 years (18 to 72) were available at a mean follow-up of 48 months (24 to 206). The quality of the reduction was ‘anatomical’ in 44 hips (73.3%) and ‘imperfect’ in 16 (26.7%). The originally achieved anatomical reduction was lost in12 patients (25.8%). Radiologically, 33 hips (55%) were graded as ‘excellent’, 11 (18.3%) as ‘good’, one (1.7%) as ‘fair’ and 15 (25%) as ‘poor’. A total of 11 further operations were required in 11 cases, of which six were total hip replacements.

Univariate linear regression analysis of the functional outcome showed that factors associated with worse pain were increasing age and an inferior location of the impaction. Elevation of the articular impaction leads to joint preservation with satisfactory overall medium-term functional results, but secondary collapse is likely to occur in some patients.

Introduction. We aim to assess whether radiographic characteristics of the greater tuberosity fragment can predict rotator cuff tears inpatients with anterior shoulder dislocations combined with an isolated fracture of the greater tuberosity. Methods. A retrospective single-centre case series of 61 consecutive patients that presented with anterior shoulder dislocations combined with an isolated fracture of the greater tuberosity between January 2018 and July 2022. Inclusion criteria: patients with atraumatic anterior shoulder dislocation associated with an isolated fracture of the greater tuberosity with a minimum follow-up of 3-months. Exclusion criteria: patients with other fractures of the proximal humerus or glenoid. Rotator cuff tears were diagnosed using magnetic resonance or ultrasound imaging. Greater tuberosity fragment size and displacement was calculated on plain radiographs using validated methods. Results. The case series was composed of 22 men and 39 women with a mean age of 65 years (29 - 91 years). The mean follow-up was 15months and median follow up 8.5 months (3 – 60 months). A rotator cuff tear was diagnosed in 14 patients (16%) and involved the supraspinatus (13), infraspinatus (4) and subscapularis (2). Full-thickness tears occurred in 6 patients and partial-thickness tears in 8patients. The mean time from initial injury to rotator cuff tear diagnosis was 5 months (2 – 22 months). The mean greater tuberosity fragment length was 23.4 mm in rotator cuff tear patients versus 32.6 mm in those without a tear (p = 0.006, CI: -15 - -2). The mean greater tuberosity. fragment width was 11.1 mm in rotator cuff tear patients versus 17.8 mm in those without a tear (p = 0.0004, CI: -10 - -2). There was no significant difference in the super inferior and anteroposterior fragment displacement between the two groups. Conclusion. In patients with shoulder dislocations combined with an isolated fracture of the greater tuberosity, rotator cuff tears are associated with a smaller sized greater tuberosity fragment

In recent years, use of anatomic stemless total shoulder arthroplasty (AsTSA) has increased. Despite evidence to suggest good mid-term results at 2-year follow-up there is a paucity of evidence for longer term follow-up. This study aimed to investigate outcomes at a minimum of 5 years post-operatively following primary AsTSA. This study is a retrospective case series of all patients who underwent a Mathys Affinis AsTSA from July 2010 (first case) to August 2018 (to allow minimum 5-year follow-up). Clinical outcomes included revision rate, range of motion and patient reported outcomes (Oxford Shoulder Score and Numerical Satisfaction Score). Radiological outcome was assessment of radiolucent lines for Lazarus grading. A total of 105 stemless TSAs were implanted. Five patients underwent revision (4.8%). Seventy-five AsTSA's were included in the final study for analysis of 5-year outcomes. Median follow-up time was 6.1 years. Median age was 69 years old and 81% were female. Oxford shoulder score showed a range of 18 to 48, with a median score of 47. Satisfied or very Satisfied was selected in 94.37%. Median range of motion assessments showed forward elevation 160°, abduction 150°, external rotation 40°, and mode internal rotation was to the lumbar spine. No glenoid lucency was present in 79.7%. There were 9.5% with Lazarus Grade 1 lucency, 5.4% with Lazarus Grade 2, and 5.4% Lazarus Grade 3. No humeral lucency was observed. This cohort study demonstrates promising clinical and radiological outcomes for the Mathys Affinis Stemless TSA at minimum 5 years post-operatively

Aims. Despite multiple trials and case series on hip hemiarthroplasty designs, guidance is still lacking on which implant to use. One particularly deficient area is long-term outcomes. We present over 1,000 consecutive cemented Thompson’s hemiarthroplasties over a ten-year period, recording all accessible patient and implant outcomes. Methods. Patient identifiers for a consecutive cohort treated between 1 January 2003 and 31 December 2011 were linked to radiographs, surgical notes, clinic letters, and mortality data from a national dataset. This allowed charting of their postoperative course, complications, readmissions, returns to theatre, revisions, and deaths. We also identified all postoperative attendances at the Emergency and Outpatient Departments, and recorded any subsequent skeletal injuries. Results. In total, 1,312 Thompson’s hemiarthroplasties were analyzed (mean age at surgery 82.8 years); 125 complications were recorded, necessitating 82 returns to theatre. These included 14 patients undergoing aspiration or manipulation under anaesthesia, 68 reoperations (5.2%) for debridement and implant retention (n = 12), haematoma evacuation (n = 2), open reduction for dislocation (n = 1), fixation of periprosthetic fracture (n = 5), and 48 revised stems (3.7%), for infection (n = 13), dislocation (n = 12), aseptic loosening (n = 9), persistent pain (n = 6), periprosthetic fracture (n = 4), acetabular erosion (n = 3), and metastatic bone disease (n = 1). Their status at ten years is summarized as follows: 1,180 (89.9%) dead without revision, 34 (2.6%) dead having had revision, 84 (6.6%) alive with the stem unrevised, and 14 (1.1%) alive having had revision. Cumulative implant survivorship was 90.3% at ten years; patient survivorship was 7.4%. Conclusion. The Thompson’s stem demonstrates very low rates of complications requiring reoperation and revision, up to ten years after the index procedure. Fewer than one in ten patients live for ten years after fracture. This study supports the use of a cemented Thompson’s implant as a cost-effective option for frail hip fracture patients.

MOXIMED KineSpring® Knee Implant System is an Orthopaedic device designed for younger or highly active patients with osteoarthritis. The device is placed under the skin, is attached to the tibia and femur, and contains springs which help limit some of the forces that are transmitted through the knee during activities such as walking or running and thereby relieve pain that may be experienced by patients with early arthritis of the knee. The aim of this study is to determine the long term safety and efficacy of the KineSpring knee implant system. This is a prospective case series involving two centres in Glasgow. 29 patients (mean age of 45.1 years and range 18-65 years) were recruited into the study between 2011 and 2016. The Primary outcome measure was Oxford knee score (OKS) at 2, 5 and 10 years post-operatively. Secondary outcome measures include device related complications and survival, patient reported functional outcome measures, patient satisfaction, pain levels and change in radiographic classification of osteoarthritis. At 2-year follow-up, 7 implants were removed (74.1% survival). Complications include deep infection, requiring removal in 1 patient, 2 implant failures requiring removal and one spring breakage. In comparison to pre-operative measures there was an improvement in the pain (3.58 vs. 5.20, p=0.02), stiffness (4.16 vs. 4.47, p=0.6) and OKS (32.4 vs. 36.9, p=0.03). The KineSpring improves overall pain, stiffness and functional outcome at 2 years following surgery, however there was a high rate of removal and further long-term follow up analysis is required regarding its effectiveness

Aims. The primary aim of this study was to determine if delayed clavicular fixation results in a greater risk of operative complications and revision surgery. Patients and Methods. A retrospective case series was undertaken of all displaced clavicular fractures that underwent plate fixation over a ten-year period (2007 to 2017). Patient demographics, time to surgery, complications, and mode of failure were collected. Logistic regression was used to identify independent risk factors contributing towards operative complications. Receiver operating characteristic (ROC) curve analysis was used to determine if a potential ‘safe window’ exists from injury to delayed surgery. Propensity score matching was used to construct a case control study for comparison of risk. Results. A total of 259 patients were included in the analysis. Postoperative infection occurred in 3.9% of all patients (n = 10); the only variable associated was a greater time interval from injury to fixation (p = 0.001). Failed primary surgery requiring revision fixation was required in 7.7% of the cohort (n = 20), with smoking (p < 0.001), presence of a postoperative infection (p < 0.001), increasing age (p = 0.018), and greater time delay from injury to surgery (p = 0.015) identified as significant independent predictors on regression analysis. ROC analysis revealed that surgery beyond 96 days from injury increased the rate of major complications and revision surgery. Using a matched case cohort of cases before (n = 67) and after (n = 77) the ‘safe window’, the risk of postoperative infection increased (odds ratio (OR) 7.7, 95% confidence interval (CI) 1.9 to 62.9; p = 0.028), fixation failure (OR 3.8, 95% CI 1.2 to 12.1; p = 0.017) and revision surgery (OR 4.8, 95% CI 1.5 to 15.0; p = 0.004). Conclusion. A delay to primary fixation of up to three months following injury may be acceptable, beyond which there is an increased risk of major operative complications and revision surgery.

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).

Methods

This is a retrospective cohort study of operatively managed orthopaedic trauma patients from 1 January 2007 to 31 December 2016, performed in Queensland, Australia. Record linkage was used to develop a person-centric, population-based dataset incorporating routinely collected administrative, clinical, and health economic information. The FRI group consisted of patients with International Classification of Disease 10th Revision diagnosis codes for deep infection associated with an implanted device within two years following surgery, while all others were deemed not infected. Demographic and clinical variables, as well as healthcare utilization costs, were compared.

Aims

The aim of this study was to compare the functional and radiological outcomes and the complication rate after nail and plate fixation of unstable fractures of the ankle in elderly patients.

Methods

In this multicentre study, 120 patients aged ≥ 60 years with an acute unstable AO/OTA type 44-B fracture of the ankle were randomized to fixation with either a nail or a plate and followed for 24 months after surgery. The primary outcome measure was the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score. Secondary outcome measures were the Manchester-Oxford Foot Questionnaire, the Olerud and Molander Ankle score, the EuroQol five-dimension questionnaire, a visual analogue score for pain, complications, the quality of reduction of the fracture, nonunion, and the development of osteoarthritis.

Aims. This study describes and compares the operative management and outcomes in a consecutive case series of patients with dislocated hemiarthroplasties of the hip, and compares outcomes with those of patients not sustaining a dislocation. Patients and Methods. Of 3326 consecutive patients treated with hemiarthroplasty for fractured neck of femur, 46 (1.4%) sustained dislocations. Of the 46 dislocations, there were 37 female patients (80.4%) and nine male patients (19.6%) with a mean age of 83.8 years (66 to 100). Operative intervention for each, and subsequent dislocations, were recorded. The following outcome measures were recorded: dislocation; mortality up to one-year post-injury; additional surgery; residential status; mobility; and pain score at one year. Results. Of 43 dislocations, 30 (70%) occurred within one month and 42 (98%) occurred within three months of hip fracture surgery. Seven (16%) of these patients were treated with a single closed reduction and sustained no further dislocations. Four (9%) were treated with open reduction and experienced no further dislocations. Three (7%) hips were left dislocated and the remaining 32 (74%) patients required additional surgery of further closed reduction, revision, or excision arthroplasty. The one-year mortality rates for patients treated with two or fewer reductions (open or closed), successful revision arthroplasty, and excision arthroplasty were 3/14 (21%), 1/7 (14%), and 8/14 (57%) respectively. The only statistically significant difference in mortality was the difference between patients who did not sustain a dislocation and those who did and were treated by excision arthroplasty (p = 0.03). Patients treated by excision arthroplasty had the greatest reduction in mobility scores and highest pain scores. The excision arthroplasty group also included the greatest proportion of patients not able to mobilize and the smallest proportion of patients remaining in their own home. Conclusion. Most dislocations of hemiarthroplasties of the hip occur within one month of surgery. Closed reduction is generally unsuccessful. For those patients with unsuccessful closed reduction, revision arthroplasty should be considered when possible, as this results in a better functional outcome with a lower mortality than excision arthroplasty

Aims

To assess the feasibility of a randomized controlled trial (RCT) that compares three treatments for acetabular fractures in older patients: surgical fixation, surgical fixation and hip arthroplasty (fix-and-replace), and non-surgical treatment.

Methods

Patients were recruited from seven UK NHS centres and randomized to a three-arm pilot trial if aged older than 60 years and had a displaced acetabular fracture. Feasibility outcomes included patients’ willingness to participate, clinicians’ capability to recruit, and dropout rates. The primary clinical outcome measure was the EuroQol five-dimension questionnaire (EQ-5D) at six months. Secondary outcomes were Oxford Hip Score, Disability Rating Index, blood loss, and radiological and mobility assessments.

Aims

The aim of this study was to investigate the rate of revision for distal femoral arthroplasty (DFA) performed as a primary procedure for native knee fractures using data from the Australian Orthopaedic Association National Joint Arthroplasty Registry (AOANJRR).

Methods

Data from the AOANJRR were obtained for DFA performed as primary procedures for native knee fractures from 1 September 1999 to 31 December 2020. Pathological fractures and revision for failed internal fixation were excluded. The five prostheses identified were the Global Modular Arthroplasty System, the Modular Arthroplasty System, the Modular Universal Tumour And Revision System, the Orthopaedic Salvage System, and the Segmental System. Patient demographic data (age, sex, and American Society of Anesthesiologists grade) were obtained, where available. Kaplan-Meier estimates of survival were used to determine the rate of revision, and the reasons for revision and mortality data were examined.

Hip fractures in young adults are rare but represent an important cohort of patients, of which relatively limited data exists. The aim of this study was to evaluate this distinct subgroup of hip fractures from an epidemiological perspective and assess their subsequent outcomes. Patients aged 18–50 were identified across an 8 year period from a total of 5326 hip fractures. 46 hip fractures met the inclusion criteria and a retrospective case series analysis was conducted. 25/46 (54%) of fractures were intracapsular and 21/46 (46%) were extracapsular. Only 15/46 (33%) of fractures were sustained from a high energy mechanism and 31/46 (67%) low energy. The low energy cohort was significantly more comorbid with a mean Elixhauser comorbidity score of 1.5 compared to the high energy cohort 0.3 (p<0.0005, unpaired t-test). Alcohol excess was the most prevalent comorbidity present in 24% of patients and was a positive predictor in complication (p=0.006, binary regression). Failure of fixation (non-union/avascular necrosis) in displaced intracapsular fractures sustained following low energy trauma managed by internal fixation 5/11 (45%) was markedly higher than the high energy cohort 0/6 (0%). 5 year mortality was 9% for all hip fractures, six times higher than an aged matched cohort of non-hip fractures (p=0.007, Wilcoxon test). Representing only 0.86% of all hip fractures in the study period, hip fractures in young adults are rare. A clear sub-division of patients is observed between patients with a low and high energy mechanism, both in terms of level of comorbidity and surgical outcome
