Aims. This study investigates the effectiveness and adequacy of the informed consent process for patients undergoing hip fracture surgery. While informed consent is a legal and ethical responsibility, factors in the trauma setting can impair patients’ understanding and retention of information. This study seeks to evaluate patients’ recall of perioperative complications and explore their perceptions of the consent process. Methods. A mixed-methods, multicentre cohort study will be conducted in the Southeast of Scotland. Adult patients with hip fractures will be recruited via consecutive sampling. An information recall questionnaire will be administered within 36 hours of admission to assess unprompted and prompted recall of complications. A subset of participants will then undergo a semi-structured qualitative interview postoperatively to explore their experiences and perceptions of the consent process. Data will be analyzed using a social constructivist grounded theory to assess their perceptions of consent. Ethical approval has been granted by the East of England Research Ethics Committee (reference 23/EE/0233). Conclusion. Findings will be disseminated through peer-reviewed publications and presentations at national and international conferences. The study results will identify challenges in the consent process, particularly in how risks are communicated and understood. The data are expected to inform the development of information aids and enhance the ability of orthopaedic surgeons to provide comprehensive, patient-centred consent.

Aims. The effectiveness of total hip arthroplasty (THA) for patients with no or minimal radiological signs of osteoarthritis (OA) is unclear. In this study, we aimed to: 1) assess the outcome of such patients; 2) identify patient comorbidities and CT or MRI findings which predicted outcome; and 3) compare their outcome to the expected outcome of THA for hip OA. Methods. Adult patients undergoing THA for hip pain, with no or minimal radiological features of OA (Tönnis grading scale ≤ 1), were identified from a consecutive series of 1,925 THAs. Exclusion criteria were: inflammatory arthritis; osteonecrosis of the femoral head; prior trauma or infection; and patients without minimum one-year follow-up and patient-reported outcome measures (PROMs). The primary outcome measure was the Oxford Hip Score (OHS). Secondary outcome measures were EuroQol-visual analogue scale (EQ-VAS), University of California and Los Angeles (UCLA) scale, and patient satisfaction on a validated three-point ‘better’, ‘same’, or ‘worse’ scale. Results. A total of 107 patients with a median age of 41 years (IQR 18 to 73) were included, with mean follow-up of 6.0 years (SD 3.1). All patients underwent a diagnostic hip injection as a decision aid. Median postoperative OHS was 34 (IQR 28 to 42), with 36 patients (33%) achieving a patient-acceptable symptom state (OHS ≥ 42), lower than THA patients in international registries (40 to 43 points). Secondary outcomes were UCLA of 6 (4 to 8) and EQ-VAS of 73 (51 to 80); 91/102 patients (89%) felt ‘better’ and would ‘undergo surgery again'. Patients with chronic pain syndrome or hypermobility had lower OHS than patients without comorbidities (-6 points, p < 0.006). Overall, 84 patients had a CT and 34 patients an MRI. Patients with subchondral cysts (OHS 42 (37 to 45) vs 35 (26 to 36); p = 0.014) or joint space narrowing on CT (OHS 42 (IQR 37 to 44) vs 35 (26 to 36); p = 0.022) had higher function. Conclusion. Despite high satisfaction levels, patients undergoing THA with minimal or no radiological OA had lower postoperative function than typical THA patients. We recommend obtaining low-dose CT imaging and a diagnostic hip injection to aid decision-making. Cite this article: Bone Jt Open 2025;6(3):328–335

Aims

Diagnostic wrist arthroscopy is considered the gold standard for evaluating wrist joint complaints. Although this tool is often used to diagnose and stage scapholunate ligament (SLL) lesions, reports about the possible findings and their clinical relevance are scarce. Therefore, this study describes the patient characteristics, arthroscopic findings, and treatment of patients who underwent diagnostic arthroscopy for suspected SLL injury.

Aims

Performance indicators are increasingly used to evaluate the quality of healthcare provided to patients with a hip fracture. The aim of this review was to map the variety of performance indicators used around the world and how they are defined.

Aims. Prevalence of artificial intelligence (AI) algorithms within the Trauma & Orthopaedics (T&O) literature has greatly increased over the last ten years. One increasingly explored aspect of AI is the automated interpretation of free-text data often prevalent in electronic medical records (known as natural language processing (NLP)). We set out to review the current evidence for applications of NLP methodology in T&O, including assessment of study design and reporting. Methods. MEDLINE, Allied and Complementary Medicine (AMED), Excerpta Medica Database (EMBASE), and Cochrane Central Register of Controlled Trials (CENTRAL) were screened for studies pertaining to NLP in T&O from database inception to 31 December 2023. An additional grey literature search was performed. NLP quality assessment followed the criteria outlined by Farrow et al in 2021 with two independent reviewers (classification as absent, incomplete, or complete). Reporting was performed according to the Synthesis-Without Meta-Analysis (SWiM) guidelines. The review protocol was registered on the Prospective Register of Systematic Reviews (PROSPERO; registration no. CRD42022291714). Results. The final review included 31 articles (published between 2012 and 2021). The most common subspeciality areas included trauma, arthroplasty, and spine; 13% (4/31) related to online reviews/social media, 42% (13/31) to clinical notes/operation notes, 42% (13/31) to radiology reports, and 3% (1/31) to systematic review. According to the reporting criteria, 16% (5/31) were considered good quality, 74% (23/31) average quality, and 6% (2/31) poor quality. The most commonly absent reporting criteria were evaluation of missing data (26/31), sample size calculation (31/31), and external validation of the study results (29/31 papers). Code and data availability were also poorly documented in most studies. Conclusion. Application of NLP is becoming increasingly common in T&O; however, published article quality is mixed, with few high-quality studies. There are key consistent deficiencies in published work relating to NLP which ultimately influence the potential for clinical application. Open science is an important part of research transparency that should be encouraged in NLP algorithm development and reporting. Cite this article: Bone Jt Open 2025;6(3):264–274

Aims. Paediatric pelvic ring fractures are rare but severe injuries, presenting significant treatment challenges. This study aimed to analyze patient characteristics and explore trends in incidence, treatment methods, and mortality associated with these injuries. Methods. This multicentre, retrospective cohort study analyzed paediatric patients (aged ≤ 18 years) with pelvic ring fractures treated between 2001 and 2021 at two level 1 trauma centres. Data on patient demographics, injury characteristics, treatment approaches, and outcomes were collected, and visual trend analysis was conducted to identify patterns. Results. A total of 157 patients with pelvic ring fractures were included. The median age was 15 years (IQR 12 to 17), with 52% (n = 81) being female. Traffic accidents were the leading cause of injury, accounting for 68% of cases (n = 106). Concomitant injuries were observed in 83% of patients (n = 131). The one-year mortality rate was 11.5%, with 76% of deaths occurring within 48 hours of admission, primarily due to traumatic brain injury (53%). Most patients (60%) were treated nonoperatively, while 48% of surgically treated patients underwent internal fixation without prior external fixation. Visual trend analysis revealed an increase in the absolute number of paediatric pelvic ring fractures over time, though no significant shift towards surgical treatment was observed. Among surgically treated patients, there was a trend towards open reduction and internal fixation rather than external fixation as definitive treatment. Nonoperative treatment was more common in children (69%) than in adolescents (55%). For surgical cases, external fixation was preferred in children (44%), while ORIF was more common in adolescents (53%). Conclusion. The incidence of paediatric pelvic ring fractures has increased over time, with a high mortality rate largely attributable to severe neurotrauma. There has been a shift towards surgical treatment without prior external fixation, with differences noted in the treatment approaches between children and adolescents, particularly in surgical fixation methods.

Aims

The risk of mortality after a hip fracture has been extensively investigated, but there is little high-quality information available dealing with the overall risk of complications. The aim of this study was to report the risk of complications in the first 120 days after a hip fracture.

The last five years have seen notable advancements in foot and ankle surgery as a result of technical innovations and more consistent reporting of results. Much progress has been made in improving patient-reported outcome measures, in the development of basic research in this area, and in the development of personalized approaches which optimize outcomes for specific groups of patients. This review focuses on five main areas of development within foot and ankle surgery: ankle arthroplasty, osteomyelitis and the diabetic foot, sports injuries, minimally invasive surgery, and orthobiologics. The aim of this annotation is to discuss the progress made in these fields during recent years and propose avenues for further development.

Aims

Core decompression is a commonly performed procedure to treat osteonecrosis of the femoral head (ONFH) prior to femoral head collapse. The aim of the study was to identify the incidence of hip arthroplasty after core decompression and the potential risk factors for conversion through a nationwide population-based study.

The use of arthroscopy of the hand and wrist has recently increased sharply in the elective setting and this, not surprisingly, has been followed by an increasing use in the trauma setting. Advocates for the use of arthroscopy in these patients cite the improved assessment of the displacement and reduction of fractures and the early diagnosis of associated injuries, while others temper this with concerns about increased operating time and possible complications. The data relating to patient-reported benefits and costs are limited. The aim of this review was to discuss the current available literature for the use of arthroscopy in the management of injuries of the hand and wrist.

Aim

One of the most common patient-reported complaints following intramedullary nailing (IMN) of tibial shaft fractures is anterior knee pain reported by 10% to 80% of patients. The present study aimed to compare the 12-month Knee injury and Osteoarthritis Outcome Score (KOOS) sport and recreation activities subscale (sport/rec) scores after IMN with external ring fixation (RF) to adult patients with tibial shaft fractures.

Aims

A large number of surgical operations are available to treat osteochondral defects of the knee. However, the knee joint arthroplasty materials cannot completely mimic the articular cartilage and subchondral bone, which may bring some obvious side effects. Thus, this study proposed a biocompatible osteochondral repair material prepared from a double-layer scaffold of collagen and nanohydroxyapatite (CHA), consisting of collagen hydrogel as the upper layer of the scaffold, and the composite of CHA as the lower layer of the scaffold.

Aims. To evaluate patient-reported outcomes three months after treatment of metacarpal and phalangeal fractures or dislocations, and to identify factors that are associated with worse patient-reported outcomes. Methods. This cross-sectional, multicentre snapshot study included all adult patients with metacarpal and phalangeal fractures or dislocations during a three-month period between August and October 2020. The primary outcome was the Michigan Hand Outcomes Questionnaire (MHQ) three months after injury. The MHQ scores were compared to normative MHQ scores of 90 points of the affected hand of patients who sustained unilateral trauma derived from a previous study. Subgroup analyses were performed for the most common injury types. Multivariable linear regression was used to study associations between patient characteristics and worse MHQ scores. Results. The MHQ scores of 512 patients were analyzed. The median MHQ score was 80 (IQR 65 to 91) for nonoperatively treated patients (n = 398) and 78 (IQR 66 to 85) for operatively treated patients (n = 114). After nonoperative treatment, 104/398 patients (26%) reached a MHQ score equal to or better than the normative MHQ score, ranging between 11% (1/9) and 42% (13/31) among the nine most common injury types. After operative treatment, this was 11% (13/114), ranging between 10% (3/29) and 31% (5/16) among the three most common injury types. No significant differences in MHQ scores were found between common injury types. Older age, the presence of hand comorbidities, and referral to hand therapy were associated with a worse MHQ score after nonoperative treatment. Conclusion. These results suggest that most patients have not returned to a normal hand function within three months following metacarpal and phalangeal fractures or dislocations. Older age, the presence of hand comorbidities, and referral for hand therapy were associated with worse hand functioning after nonoperative treatment. The findings are relevant for clinicians to evaluate recovery and for patients to manage their expectations. Cite this article: Bone Jt Open 2025;6(2):227–236

Aims. Fracture-related infections (FRIs) are a major concern for patients and healthcare systems, yet their impact on mental health has been largely overlooked. This study aimed to assess the longitudinal impact of FRI on patients’ quality of life. Methods. A prospective study was conducted at a level 1 trauma centre between January 2020 and December 2022. In total, 56 patients participated, with quality of life assessed at five timepoints: one week preoperatively, and one, three, six, and 12 months postoperatively. Statistical analysis was performed using repeated measures analysis of variance (ANOVA) with adjusted post-hoc analysis. Results. The preoperative Physical Component Summary score on the 36-Item Short-Form Health Survey questionnaire (SF-36) was 26.71, increasing to 30.40 at one month, remaining stable at three months. A modest increase was observed at six months (32.45, p = 0.003), but it decreased to 29.72 at 12 months. The preoperative Mental Component Summary score (SF-36) was 46.48, decreasing to 39.89 at one month (p = 0.027) and to 36.03 at three months (p ≤ 0.001). However, it improved at six (42.74) and 12 months (44.05). Positive changes were seen in EuroQol five-dimension questionnaire (EQ-5D) subdimensions, such as mobility, self-care, usual activities, and pain/discomfort, while anxiety/depression scores decreased over time. The EQ-5D visual analogue scale (VAS) score increased to 62.79 at six months (p ≤ 0.001) and decreased to 58.2 at 12 months (p = 0.011). Conclusion. FRIs substantially affect mental health and quality of life, particularly during the initial three months of treatment. This study emphasizes the importance of addressing psychological aspects early in FRI management, advocating for holistic care encompassing both physical and psychological aspects of treatment.

Aims

To develop a multidisciplinary health research agenda (HRA) utilizing expertise from various disciplines to identify and prioritize evidence uncertainties in orthopaedics, thereby reducing research waste.

Aims. Autologous bone graft (ABG) is considered the ‘gold standard’ among graft materials for bone regeneration. However, complications including limited availability, donor site morbidity, and deterioration of regenerative capacity over time have been reported. P-15 is a synthetic peptide that mimics the cell binding domain of Type-I collagen. This peptide stimulates new bone formation by enhancing osteogenic cell attachment, proliferation, and differentiation. The objective of this study was to conduct a systematic literature review to determine the clinical efficacy and safety of P-15 peptide in bone regeneration throughout the skeletal system. Methods. PubMed, Embase, Web of Science, and Cochrane Library were searched for relevant articles on 13 May 2023. The systematic review was reported according to the PRISMA guidelines. Two reviewers independently screened and assessed the identified articles. Quality assessment was conducted using the methodological index for non-randomized studies and the risk of bias assessment tool for randomized controlled trials. Results. After screening, 28 articles were included and grouped by surgical indication, e.g. maxillofacial procedures (n = 18), spine (n = 9), and trauma (n = 1). Published results showed that P-15 peptide was effective in spinal fusion (n = 7) and maxillofacial (n = 11), with very few clinically relevant adverse events related to P-15 peptide. Conclusion. This systematic literature review concluded that moderate- (risk of bias, some concern: 50%) to high-quality (risk of bias, low: 46%) clinical evidence exists showing equivalent safety and efficacy in bone regeneration using a P-15 peptide enhanced bone graft substitute compared to ABG. P-15 peptide is safe and effective, resulting in rapid bone formation with a low probability of minor complications. Cite this article: Bone Joint Res 2025;14(2):77–92

The February 2025 Hip & Pelvis Roundup³⁶⁰ looks at: Postoperative periprosthetic femoral fractures after hip arthroplasty: quantifying the other half of the picture; Hip arthroscopy in patients with borderline dysplasia: how do we know when it will not work?; The morbidly obese patient remains a challenge for arthroplasty surgeons; Unexpected positive cultures in aseptic revision hip and knee arthroplasty: does it make a difference?; Failed spinal anaesthesia in hip and knee arthroplasty surgery; Clinical failure of femoral neck fracture is associated with varus necks; Navigating the angles: how variations in femoral and acetabular versions influence hip pain and treatment; High-tech or hands-on? Similar outcomes in direct anterior total hip arthroplasty.

Aims. The aim of the study was to apply 3D measurements for fracture displacement in minimally to moderately displaced acetabular fractures treated nonoperatively, and to evaluate whether this measurement can be used to estimate the likelihood of conversion to total hip arthroplasty (THA) at follow-up. Methods. A multicentre, cross-sectional study was performed on 144 patients who were treated nonoperatively for an acetabular fracture in four level 1 trauma centres between January 2000 and December 2020. For each patient, fracture displacement was measured on CT-based 3D models. The 3D gap area represents fracture displacement (mm. 2. ) between all fracture fragments. A receiver operating characteristic curve was generated to determine a 3D gap area threshold representing the optimal sensitivity and specificity to predict conversion to THA. Native hip survival was reported using Kaplan-Meier curves. Predictors of conversion to THA were determined using Cox regression analysis. Results. Of 144 patients, 18 (12%) received a THA. The median 3D gap area of the complete study cohort was 692 mm. 2. (IQR 216 to 1,400). Native hip survival in patients with a gap area threshold ≤ 1,171 or > 1,171 mm. 2. differed at one-year (98% vs 85%), two-year (96% vs 77%), and five-year follow-up (92% vs 73%). 3D gap area > 1,171 mm. 2. (hazard ratio (HR) 4.3; 95% CI 1.7 to 11.0) and the presence of osteoarthritis grade 2 or higher (HR 3.1; 95% CI 1.2 to 7.8) independently predicted the likelihood of conversion to THA during follow-up. Conclusion. For nonoperatively treated acetabular fractures, introducing 3D gap area assessment to measure fracture displacement offers a promising approach for assessing the risk of conversion to THA. With the introduction of (semi-)automatic segmentation and measurement techniques, or their implementation into commercially available software, this 3D gap area measurement can serve as an addition to the Letournel classification and an alternative to traditional 2D gap and step-off measurements, improving accuracy, reproducibility, and applicability in clinical decision-making.

Aims

HIV and musculoskeletal injuries both disproportionately affect individuals living in low- and middle-income countries (LMICs), leading to a significant number of fractures in HIV-positive patients. Despite this, little is known about the long-term outcomes for these patients. This prospective cohort study investigated whether HIV infection is associated with fracture-related infections (FRIs).

Aims

Over time, the locking mechanism of Modular Universal Tumour and Revision System (MUTARS) knee arthroplasties changed from polyethylene (PE) to polyether-ether-ketone Optima (PEEK) and metal-on-metal (MoM) in an attempt to reduce the risk of mechanical failure. In this study, we aimed to assess the cumulative incidence of locking mechanism revision for symptomatic instability by type of material, and assess potential associated risk factors.

Hip fractures commonly occur in older patients, with high levels of frailty and comorbidity. Many of these patients have limited mobility before their fracture, and even after surgery, their mobility may remain limited. It is therefore not surprising that they are at a high risk of developing pressure sores, particularly on their heels, and a variety of devices and interventions have been proposed to reduce this risk. Foam or air mattresses, designed to reduce contact pressure on the patient’s whole body, are now routinely used in many healthcare systems. However, there is wide variation in their design. We developed the WHiTE 14;PRESSURE 3 trial to address the lack of evidence in this area. This is a three-arm multicentre randomized trial including health economic evaluation and recruiting patients from NHS hospitals in the UK. The trial compares standard strategies for the prevention of pressure sores with standard care plus a constant low-pressure device and with standard care plus a heel off-loading device. This annotation describes the development of this trial.

Aims. The aims of this study, using a porcine model of multiple trauma, were to investigate the expression of microRNAs at the fracture site, in the fracture haematoma (fxH) and in the fractured bone, compared with a remote unfractured long bone, to characterize the patterns of expression of circulating microRNAs in plasma, and identify and validate messenger RNA (mRNA) targets of the microRNAs. Methods. Two multiple trauma treatment strategies were compared: early total care (ETC) and damage control orthopaedics (DCO). For this study, fxH, fractured bone, unfractured control bone, plasma, lung, and liver samples were harvested. MicroRNAs were analyzed using quantitative real-time polymerase chain reaction arrays, and the identified mRNA targets were validated in vivo in the bone, fxH, lung, and liver tissue. Results. MicroRNA expression was associated with the trauma treatment strategy and differed depending on the type of sample. In the ETC group, a more advanced fracture healing response, as reflected by the expression of osteogenic microRNAs, was seen compared with the DCO group. DCO treatment resulted in a more balanced immune response in the systemic circulation as represented by significant upregulations of several anti-inflammatory microRNAs. The in vivo validation of the abundance of putative mRNA targets reflected the levels of microRNAs which were identified. Conclusion. Local and systemic microRNA patterns of expression were identified, specific for the treatment strategy in multiple trauma, which corresponded with the expression of mRNA at the fracture site and in target organs. These findings match clinical observations and offer insights into the cellular communication which may underlie the effects of using different surgical strategies in patients with multiple trauma, both locally and systemically. We also identified a systemic involvement of microRNAs in multiple trauma which may include distant cellular communication between injured tissues. Further research may further describe the temporospatial role of circulating microRNAs after multiple trauma, their potential role in communication between organs, and prospective therapeutic applications.

Aims

While cementless fixation offers potential advantages over cemented fixation, such as a shorter operating time, concerns linger over its higher cost and increased risk of periprosthetic fractures. If the risk of fracture can be forecasted, it would aid the shared decision-making process related to cementless stems. Our study aimed to develop and validate predictive models of periprosthetic femoral fracture (PPFF) necessitating revision and reoperation after elective total hip arthroplasty (THA).

Aims. Trauma & Orthopaedic (T&O) surgery has come under scrutiny for lagging behind other medical specialties in promoting gender and cultural equity and diversity within their workforce. The proportions of female, ethnic minority, and sexual and gender minority individuals within orthopaedic membership bodies are disproportionate to the populations they serve. The aim of this study is to report the findings of a national workforce survey of demographics and working patterns within T&O in Scotland. Methods. A questionnaire devised by a working group was delivered by the Client Analyst and Relationship Development (CARD) group. Utilizing a secure third party ensured anonymity for all respondents. Data were recorded and analyzed by the CARD group. Results. A total of 353 responses were recorded, representing 71% of the known workforce. Overall, 261 respondents (74%) identified as male, 85 (24%) female, and seven (2%) preferred not to say. For specialist trainee (ST)3 to ST6, 148 (42%) were female, and for ST7 to ST8, 131 (37%) were female. In total, 226 of all respondents (64%) were white-British, 35 (10%) were white-European, and 92 (26%) were of an ethnic minority background. A total of 321 of respondents (91%) identified as heterosexual, 14 (4%) preferred not to say, and 18 (5%) identified as LGBTQ+ or preferred to self-describe. Conclusion. This is the largest national workforce survey in contemporary surgical literature. The findings demonstrate a greater proportion of female surgeons overall compared to other studies in T&O. This proportion of females was highest among more junior trainees. The Scottish T&O workforce is more ethnically diverse than the demographics of the population it serves. This study suggests that T&O in Scotland is an evolving speciality in terms of equality and diversity, and is making positive progress. Cite this article: Bone Jt Open 2025;6(1):103–108

Aims

Magnesium ions (Mg²⁺) play an important role in promoting cartilage repair in cartilage lesions. However, no research has focused on the role of Mg²⁺ combined with microfracture (MFX) in hyaline-like cartilage repair mediated by cartilage injury. This study aimed to investigate the beneficial effects of the combination of MFX and Mg²⁺ in cartilage repair.

Aims. The aim of this study was to explore differences in operative autonomy by trainee gender during orthopaedic training in Ireland and the UK, and to explore differences in operative autonomy by trainee gender with regard to training year, case complexity, index procedures, and speciality area. Methods. This retrospective cohort study examined all operations recorded by orthopaedic trainees in Ireland and the UK between July 2012 and July 2022. The primary outcome was operative autonomy, which was defined as the trainee performing the case without the supervising trainer scrubbed. Results. A total of 3,533,223 operations were included for analysis. Overall, male trainees performed 5% more operations with autonomy than female trainees (30.5% vs 25.5%; 95% CI 4.85 to 5.09). Female trainees assisted for 3% more operations (35% vs 32%; 95% CI 2.91 to 3.17) and performed 2% more operations with a supervising trainer scrubbed (39% vs 37%; 95% CI 1.79 to 2.06). Male trainees performed more operations with autonomy than female trainees in every year of training, in each category of case complexity, for each orthopaedic speciality area, and for every index procedure except nerve decompression. When adjusting for year, training level, case complexity, speciality area, and urgency, male trainees had 145% (95% CI 2.18 to 2.76) increased odds of performing an operation with autonomy and 35% (95% CI 1.25 to 1.45) increased odds of performing an operation under trainer supervision, than assisting, compared to female trainees. Conclusion. Male trainees perform more operations with autonomy during orthopaedic training than female trainees. Female orthopaedic trainees assist for a greater proportion of cases than their male counterparts. A comprehensive review of trauma and orthopaedic training is needed to identify any additional differences in training opportunities between female and male trainees, particularly with regard to progression through training.

Overall sagittal flexion is restricted in patients who have undergone both lumbar fusion and total hip arthroplasty (THA). However, it is not evident to what extent this movement is restricted in these patients and how this influences quality of life (QoL). The purpose of this study was to determine the extent to which hip-lumbar mobility is decreased in these patients, and how this affects their QoL score.

Aims

Hemiarthroplasty (HA) and total shoulder arthroplasty (TSA) are often the preferred forms of treatment for patients with atraumatic avascular necrosis of the humeral head when conservative treatment fails. Little has been reported about the survival of HA and TSA for this indication. The aim of this study was to investigate the differences in revision rates between HA and TSA in these patients, to determine whether one of these implants has a superior survival and may be a better choice in the treatment of this condition.

Hallux valgus (HV) presents as a common forefoot deformity that causes problems with pain, mobility, footwear, and quality of life. The most common open correction used in the UK is the Scarf and Akin osteotomy, which has good clinical and radiological outcomes and high levels of patient satisfaction when used to treat a varying degrees of deformity. However, there are concerns regarding recurrence rates and long-term outcomes. Minimally invasive or percutaneous surgery (MIS) has gained popularity, offering the potential for similar clinical and radiological outcomes with reduced postoperative pain and smaller scars. Despite this, MIS techniques vary widely, hindering comparison and standardization. This review evaluates the evidence for both open Scarf and Akin osteotomy and newer-generation MIS techniques. Fourth-generation MIS emphasizes multiplanar rotational deformity correction through stable fixation. While MIS techniques show promise, their evidence mainly comprises single-surgeon case series. Comparative studies between open and MIS techniques suggest similar clinical and radiological outcomes, although MIS may offer advantages in scar length and less early postoperative pain. MIS may afford superior correction in severe deformity and lower recurrence rates due to correcting the bony deformity rather than soft-tissue correction. Recurrence remains a challenge in HV surgery, necessitating long-term follow-up and standardized outcome measures for assessment. Any comparison between the techniques requires comparative studies. Surgeons must weigh the advantages and risks of both open and MIS approaches in collaboration with patients to determine the most suitable treatment.

Aims

Prolonged waits for hip and knee arthroplasty have raised questions about the equity of current approaches to waiting list prioritization for those awaiting surgery. We therefore set out to understand key stakeholder (patient and surgeon) preferences for the prioritization of patients awaiting such surgery, in order to guide future waiting list redesign.

Aims

Frozen shoulder is a common and debilitating condition characterized by pain and restricted movement at the glenohumeral joint. Various treatment methods have been explored to alleviate symptoms, with suprascapular nerve block (SSNB) emerging as a promising intervention. This meta-analysis aimed to assess the effectiveness of SSNB in treating frozen shoulder.

Aims

It is unclear if a supportive bandage, removable splint, or walking cast offers the best outcome following low-risk ankle fractures in children. The aim of this study was to evaluate the feasibility of a randomized controlled trial to compare these treatments.

Aims. The free latissimus dorsi muscle (LDM) flap represents a workhorse procedure in the field of trauma and plastic surgery. However, only a small number of studies have examined this large group of patients with regard to the morbidity of flap harvest. The aim of this prospective study was therefore to objectively investigate the morbidity of a free LDM flap. Methods. A control group (n = 100) without surgery was recruited to assess the differences in strength and range of motion (ROM) in the shoulder joint with regard to handedness of patients. Additionally, in 40 patients with free LDM flap surgery, these parameters were assessed in an identical manner. Results. We measured higher values for all parameters assessing force in the shoulder joint on the dominant side of patients in the control group. Moreover, LDM flap harvest caused a significant reduction in strength in the glenohumeral joint in all functions of the LDM that were assessed, ranging from 9.0% to 13.8%. Equally, we found a significantly reduced ROM in the shoulder at the side of the flap harvest. For both parameters, this effect was diminished, when the flap harvest took place on the dominant side of the patient. Conclusion. LDM flap surgery leads to a significant impairment of the strength and ROM in the shoulder joint. Moreover, the donor morbidity must be differentiated with regard to handedness: harvest on the non-dominant side potentiates the already existing difference in strength and ROM. Conversely, if the harvest takes place on the dominant side of the patient, this difference is diminished. Cite this article: Bone Jt Open 2024;5(12):1114–1119

Aims

Arthroplasty has been shown to generate the most waste among all orthopaedic subspecialties, and it is estimated that hip and knee arthroplasty generate in excess of three million kg of waste annually in the UK. Infectious waste generates up to ten times more CO2 compared with recycled waste, and previous studies have shown that over 90% of waste in the infectious stream is misallocated. We assessed the effect of real-time waste segregation by an unscrubbed team member on waste generation in knee and hip arthroplasty cases, and compared this with a simple educational intervention during the ‘team brief’ at the start of the operating list across two sites.

Addressing bone defects is a complex medical challenge that involves dealing with various skeletal conditions, including fractures, osteoporosis (OP), bone tumours, and bone infection defects. Despite the availability of multiple conventional treatments for these skeletal conditions, numerous limitations and unresolved issues persist. As a solution, advancements in biomedical materials have recently resulted in novel therapeutic concepts. As an emerging biomaterial for bone defect treatment, graphene oxide (GO) in particular has gained substantial attention from researchers due to its potential applications and prospects. In other words, GO scaffolds have demonstrated remarkable potential for bone defect treatment. Furthermore, GO-loaded biomaterials can promote osteoblast adhesion, proliferation, and differentiation while stimulating bone matrix deposition and formation. Given their favourable biocompatibility and osteoinductive capabilities, these materials offer a novel therapeutic avenue for bone tissue regeneration and repair. This comprehensive review systematically outlines GO scaffolds’ diverse roles and potential applications in bone defect treatment.
