Acute metatarsal fractures are a common extremity injury. While surgery may be recommended to reduce the risk of nonunion or symptomatic malunion, most fractures are treated with nonoperative management. However, there is significant variability between practitioners with no consensus among clinicians on the most effective nonoperative protocol, despite how common the form of treatment. This systematic review identified published conservative treatment modalities for acute metatarsal fractures and compares their non-union rate, chronic pain, and length of recovery, with the objective of identifying a best-practices algorithm. Searches of CINAHL, EMBASE, MEDLINE, and CENTRAL identified clinical studies, level IV or greater in LOE, addressing non-operative management strategies for metatarsal fractures. Two reviewers independently screened the titles, abstracts, and full texts, extracting data from eligible studies. Reported outcome measures and complications were descriptively analyzed. Studies were excluded if a rehabilitation program outlining length of immobilization, weight-bearing and/or strengthening approaches was not reported. A total of 12 studies (8 RCTs and 4 PCs), from the 2411 studies that were eligible for title screening, satisfied inclusion criteria. They comprised a total of 610 patients with acute metatarsal fractures, with a mean age of 40.2 years (range, 15 – 82). There were 6 studies that investigated avulsion fractures, 2 studies on true Jones fractures, and 4 studies with mixed fracture types. Studies assessed a variety of treatment modalities including: WB and NWB casts, elasticated support bandages, hard-sole shoes, plaster slippers, metatarsal shoe casts, and air cast boots. Most studies investigated the outcomes of NWB casts and elasticated support bandages. The NWB short leg cast had no reported non-unions, delayed-unions, or refractures for avulsion fractures. In true Jones fractures, there was an average non-union rate of 23.6% (range, 5.6 – 27.8%), delayed-union rate of 11.8% (range, 5.6 – 18.8%), and refracture rate of 3% (range, 0 – 5.6%). Overall, the average AOFAS score was 87.2 (range, 84 – 91.7) and the average VAS score was 83.7 (range, 75 – 93). The elasticated support bandage had an average non-union rate of 3.4% (range, 0 – 12%), and delayed-union rate of 3.8% for acute avulsion fractures, with no reported refractures. No included study arm investigated outcomes of elasticated support bandages for the true Jones fracture. The average AOFAS score for elasticated support bandages was 93.5 (range, 90 – 100). The average VAS score was 88.9 (range, 90 – 100). Most acute metatarsal fractures heal well, with good-to-excellent functional outcomes and moderate-to-high patient satisfaction. Conservative strategies for avulsion fractures are highly successful and based on this data the authors recommend patients undergo a schedule that involves 3 – 4 weeks in an elasticated support bandage, short leg cast, or equivalent, and WB thereafter as tolerated, with return-to-activity after clinical union. Despite poorer conservative outcomes for true Jones fractures, patients should undergo 8 weeks in a NWB short leg cast, followed by a walking cast or hard-sole shoe for an additional 4 – 6 weeks, or until clinical union. However, surgical consultation is recommended

There is very limited literature describing the outcomes of management for proximal humerus fractures with more than 100% displacement of the head and shaft fragments as a separate entity. This study aimed to compare operative and non-operative management of the translated proximal humerus fracture.

A prospective cohort study was performed including patients managed at a Level 1 trauma centre between January 2010 to December 2018. Patients with 2, 3 and 4-part fractures were included based on the degree of translation of the shaft fragment (≥100%), resulting in no cortical contact between the head and shaft fragments. Outcome measures were the Oxford Shoulder Score (OSS), EQ-5D-5L, and radiological outcomes. Complications recorded included further surgery, loss of position/fixation, and non-union/malunion. Linear and logistic regression models were used to compare management options.

There were 108 patients with a proximal humerus fracture with ≥100% translation; 76 underwent operative management and 32 were managed non-operatively with sling immobilisation. The mean (SD) age in the operative group was 54.3 (±20.2) and in the non-operative group was 73.3 (±15.3) (p<0.001). There was no association between OSS and management options (mean 38.5(±9.5) operative vs mean 41.3 (±8.5) non-operative, p=0.48). Operative management was associated with improved health status outcomes; EQ-5D utility score adjusted mean difference 0.16 (95%CI 0.04-0.27, p=0.008); EQ-5D VAS adjusted mean difference 19.2 (95%CI 5.2-33.2, p=0.008). Operative management was further associated with a lower odds of non-union (adjusted OR 0.30, 95%CI 0.09-0.97, p=0.04), malunion (adjusted OR 0.14, 95%CI 0.04-0.51, p=0.003) and complications (adjusted OR 0.07, 95%CI 0.02-0.32, p=0.001).

Translated proximal humerus fractures with ≥100% displacement demonstrate improved health status and radiological outcomes following surgical fixation. Patients with this injury should be considered for operative intervention.

This systematic review and meta-analysis aimed to compare the outcome of operative and non-operative management in adults with distal radius fractures, with an additional elderly subgroup analysis. The main outcome was 12-month PRWE score. Secondary outcomes included DASH score, grip strength, complications and radiographic parameters.

Randomised controlled trials of patients aged ≥18yrs with a dorsally displaced distal radius fractures were included. Studies compared operative intervention with non-operative management. Operative management included open reduction and internal fixation, Kirschner-wiring or external fixation. Non-operative management was cast/splint immobilisation with/without closed reduction. Version 2 of the Cochrane risk-of-bias tool was used.

After screening 1258 studies, 16 trials with 1947 patients (mean age 66yrs, 76% female) were included in the meta-analysis. Eight studies reported PRWE score and there was no clinically significant difference at 12 weeks (MD 0.16, 95% confidence interval [CI] −0.75 to 1.07, p=0.73) or 12 months (mean difference [MD] 3.30, 95% CI −5.66 to −0.94, p=0.006). Four studies reported on scores in the elderly and there was no clinically significant difference at 12 weeks (MD 0.59, 95% CI −0.35 to 1.53, p=0.22) or 12 months (MD 2.60, 95% CI −5.51 to 0.30, p=0.08). There was a no clinically significant difference in DASH score at 12 weeks (MD 10.18, 95% CI −14.98 to −5.38, p<0.0001) or 12 months (MD 3.49, 95% CI −5.69 to −1.29, p=0.002). Two studies featured only elderly patients, with no clinically important difference at 12 weeks (MD 7.07, 95% CI −11.77 to −2.37, p=0.003) or 12 months (MD 3.32, 95% CI −7.03 to 0.38, p=0.08).

There was no clinically significant difference in patient-reported outcome according to PRWE or DASH at either timepoint in the adult group as a whole or in the elderly subgroup.

Aim

We outline a treatment protocol for subjects with chronic periprosthetic joint infections (PJI) who elected not to have surgery. We developed a method of serial “fluid-depleting” aspirations with intra-articular gentamycin injections to affect the population of the biofilm community. We have experienced many treatment failures, as expected, but have also had a group of subjects who responded exceptionally well, requiring no surgical intervention. Our longest follow-up is 10 years.

Flail chest and multiple rib fractures are common injuries in trauma patients. Several small randomized studies have suggested significant improvements in patient outcomes with surgical fixation, compared to nonoperative management, yet emerging population-level data report some conflicting results. The objectives of this study were to compare the results of surgical fixation and nonoperative management of multiple rib fractures and flail chest injuries and to assess whether effects varied by study design limitations, including risk of confounding by indication. A comprehensive search of electronic databases (Medline, Embase, Web of Science) was performed to identify randomized controlled trials and observational studies. Random effects models were used to evaluate weighted risk ratios (RR) and mean differences (MD). Risk of confounding by indication was assessed for each study (low, medium, and high risk), and this categorization was used to stratify results for clinical outcomes. Publication bias was assessed. Thirty-nine studies, with a total of 19,357 patients met inclusion criteria. Compared to nonoperative treatment, surgical fixation of flail chest and multiple rib fractures was associated with decreased risk of death (overall RR 0.40, 95% confidence interval (CI) 0.28–0.56), pneumonia (overall RR 0.70, 95% CI 0.52–0.93), tracheostomy (overall RR 0.62, 95% CI 0.41–0.93), and chest wall deformity (overall RR 0.16, 95% CI 0.06–0.42). However, many of the observational studies were at risk of confounding by indication, and results varied according to risk of confounding by indication. Differences in ventilator time, intensive care unit length of stay (LOS), hospital LOS, and return to work will be assessed (results pending). Compared to nonoperative treatment, surgical fixation of flail chest and multiple rib fractures is associated with improved clinical outcomes. Discrepancies between some study results may be due to confounding by indication. Additional prospective randomized trials and high-quality observational studies are required to overcome potential threats to validity and to expand on existing evidence around optimal treatment of these injuries

This review compares the outcomes and complication rates of three surgical strategies used for the management of symptomatic os acromiale. The purpose of this study was to help guide best practice recommendations. A systematic review of nine prospective studies, seven retrospective studies, and three case studies published across ten countries between 1993 and 2018 was performed. Adult patients (i.e., ≥ 18 years of age) with a symptomatic os acromiale that failed nonoperative management were included in this review. Surgical techniques utilized within the included studies include excision, acromioplasty, and open reduction and internal fixation (ORIF). The primary outcomes of interest included patient satisfaction and return to activity. Range of motion and several standardized outcome measurement tools were also included in the final analysis. Patient satisfaction was highest in the excision and ORIF groups, with 92% and 82% of patients reporting good to excellent postoperative results, respectively, compared to 63% in the acromioplasty group. All three patient groups experienced improved postoperative objective scores (i.e., patient-reported outcome scores and active range of motion). The excision group experienced a complication rate of 1%, while the acromioplasty group experienced a complication rate of 11% and the ORIF group a rate of 67%. This study reports on the largest sample of patients who have undergone surgical treatment for a symptomatic os acromiale. We have demonstrated that excision of the os with repair of the deltoid resulted in the best clinical outcomes with the least complications. In healthy adult patients with a large os fragment and a normal rotator cuff, surgical fixation may provide increased preservation of deltoid function while offering good patient satisfaction. Such patients should be aware that they are at increased risk of requiring a second procedure due to symptomatic hardware following ORIF

Arthrosis of the hip joint can be a significant source of pain and dysfunction. While hip replacement surgery has emerged as the gold standard for the treatment of end stage coxarthrosis, there are several non-arthroplasty management options that can help patients with mild and moderate hip arthritis. Therefore, the purpose of this paper is to review early prophylactic interventions that may help defer or avoid hip arthroplasty. Nonoperative management for the symptomatic hip involves minimizing joint inflammation and maximizing joint mobility through intra-articular joint injections and exercise therapy. While weight loss, activity modifications, and low impact exercises is generally recommended for patients with arthritis, the effects of these modalities on joint strength and mobility are highly variable. Intra-articular steroid injections tended to offer reliable short-term pain relief (3–4 weeks) but provided unreliable long-term efficacy. Additionally, injections of hyaluronic acid do not appear to provide improved pain relief compared to other modalities. Finally, platelet rich plasma injections do not perform better than HA injections for patients with moderate hip joint arthrosis. Primary hip joint arthrosis is rare, and therefore treatment such as peri-acetabular osteotomies, surgical dislocations, and hip arthroscopy and related procedures are aimed to minimise symptoms but potentially aim to alter the natural history of hip diseases. The state of the articular cartilage at the time of surgery is critical to the success or failure of any joint preservation procedures. Lech et al. reported in a series of dysplastic patients undergoing periacetabular osteotomies that one third of hips survived 30 years without progression of arthritis or conversion to THA. Similarly, surgical dislocation of the hip, while effective for treatment of femoroacetabular impingement, carries a high re-operation rate at 7 years follow up. Finally, as the prevalence of hip arthroscopic procedures continues to rise, it is important to recognise that failure to address the underlying structural pathologies can lead to failure and rapid joint destruction. In summary, several treatment modalities are available for the management of hip pain and dysfunction in patients with a preserved joint space. While joint preservation procedures can help improve pain and function, they rarely alter the natural history of hip disease. The status of the articular cartilage at the time of surgery is the most important predictor of treatment success or failure

To examine the effect of lateral spine curvature on somatosensory evoked potentials (SSEP) in patients with adolescent idiopathic scoliosis (AIS) compared to normal controls. We hypothesise that patients with AIS will show increased latency in their SSEPs when bending into their curve suggesting that their spinal cord is more sensitive to this increased lateral curvature. Patients were recruited from the paediatric scoliosis clinic in a single centre. Inclusion criteria were: diagnosis of AIS, age 10–18 years, major thoracic curve measuring greater than 10 degrees on Cobb measurement, and undergoing nonoperative management. Exclusion criteria were: any detectable neurologic deficit, and previous surgery on the brain or spine. SSEP recordings were obtained via stimulation of the posterior tibial nerve with surface electrode and measurement of the cortical response over the scalp. All recordings were performed three times: with the patient in neutral standing and maximum right and left side bending. SSEP recordings show that when AIS subjects bend into their curve, latency slows by an average of 0.5ms. However there was a bimodal distribution with most subjects showing minimal change (3ms). This subset was statistically different from both a control group, and the larger AIS group. There appears to be a subset of patients with AIS who have subclinical spinal cord dysfunction demonstrated by abnormal SSEPs. This may place these patients at slightly higher risk of neurologic injury at the time of surgery

Osteoid osteoma is a benign bone-forming lesion, characterized by its small size, its clearly demarcated outline and by the usual presence of a surrounding zone of reactive bone formation. It often poses a diagnostic challenge due to its ambiguous presentation. The aetiology of osteoid osteoma is poorly understood. The previous suggestion that osteoid osteoma was not associated with trauma or infection has been challenged by more recent literature raising the possibility that it could be a reactive or healing response or a phenomenon associated with the revascularisation process. This case report describes an unusual presentation of a post-traumatic osteoid osteoma. Two years following a diaphyseal, spiral tibial fracture treated nonoperatively, the patient developed new pain at the previous fracture site. The pain was constant, relieved by non-steroidal analgesia and not associated with systemic upset. It was initially attributed to other more likely diagnoses such as osteomyelitis and neuropathic pain. Multiple investigations and interventions were undertaken prior to the definitive diagnosis being obtained by surgical excision of the lesion and histological studies five years after the injury and three years following the initiation of the discomfort. In both English and foreign language literature there are only seven case reports that document osteoid osteoma following fracture, these are predominantly in the lower limb with no predominance to operative or nonoperative management. This case report should raise the index of clinical suspicion of osteoid osteoma occurring post fracture

Purpose. A recent multicentre randomized control trial (RCT) failed to demonstrate superior quality of life at one year following open reduction and internal fixation (ORIF) compared to nonoperative treatment for unstable isolated fibular fractures. We sought to determine the cost-effectiveness of ORIF compared to non-operative management of unstable fibular fractures. Method. A decision tree was used to model the results of a multicentre trial comparing ORIF versus nonoperative treatment for isolated fibular fractures. A single payer, governmental perspective was used for the analysis. Utilities (a measure of preference for a health state) were obtained from the subjects Short-Form-6D scores and used to calculated Quality Adjusted Life Years (QALYs). Probabilities for each strategy were taken from the one-year trial endpoint. Costs were obtained from the Ontario Case Costing Initiative. Sensitivity analysis was performed for all model variables to determine when ORIF is a cost-effective treatment (incremental cost per QALY gained < $75,000). Results. Nonoperative management was the preferred treatment during the one-year time-horizon. The nonoperative treatment strategy had an average cost of $2,099 $885 for an average gain of 0.717 0.064 QALYs. ORIF had an average cost of $6,455 $3,589 for an average gain of 0.734 0.051 QALYs. The incremental cost effectiveness ratio for the ORIF treatment was $256,235 per QALY. ORIF becomes the preferred treatment at extreme values for its costs (< $1,450) and its effectiveness (QALY > 0.81). Conclusion. From a single-payer, governmental perspective open reduction and internal fixation does not appear to be cost-effective; however, if operative fixation decreases the lifetime incidence of post-traumatic ankle arthrosis or a broader societal perspective with a higher willingness to pay threshold is adopted, then the economic attractiveness of ORIF would improve

Despite the vast quantities of published artificial intelligence (AI) algorithms that target trauma and orthopaedic applications, very few progress to inform clinical practice. One key reason for this is the lack of a clear pathway from development to deployment. In order to assist with this process, we have developed the Clinical Practice Integration of Artificial Intelligence (CPI-AI) framework – a five-stage approach to the clinical practice adoption of AI in the setting of trauma and orthopaedics, based on the IDEAL principles (https://www.ideal-collaboration.net/). Adherence to the framework would provide a robust evidence-based mechanism for developing trust in AI applications, where the underlying algorithms are unlikely to be fully understood by clinical teams.

Aims

The aim of this study is to determine the effects of the UK lockdown during the COVID-19 pandemic on the orthopaedic admissions, operations, training opportunities, and theatre efficiency in a large district general hospital.

Aims

To determine the impact of COVID-19 on orthopaediatric admissions and fracture clinics within a regional integrated care system (ICS).

Aims

The current global pandemic due to COVID-19 is generating significant burden on the health service in the UK. On 23 March 2020, the UK government issued requirements for a national lockdown. The aim of this multicentre study is to gain a greater understanding of the impact lockdown has had on the rates, mechanisms and types of injuries together with their management across a regional trauma service.

Aims

The COVID-19 pandemic presents an unprecedented burden on global healthcare systems, and existing infrastructures must adapt and evolve to meet the challenge. With health systems reliant on the health of their workforce, the importance of protection against disease transmission in healthcare workers (HCWs) is clear. This study collated responses from several countries, provided by clinicians familiar with practice in each location, to identify areas of best practice and policy so as to build consensus of those measures that might reduce the risk of transmission of COVID-19 to HCWs at work.

Aims

This study aims to define the epidemiology of trauma presenting to a single centre providing all orthopaedic trauma care for a population of ∼ 900,000 over the first 40 days of the COVID-19 pandemic compared to that presenting over the same period one year earlier. The secondary aim was to compare this with population mobility data obtained from Google.
