RESUMEN
Background: Thumb carpometacarpal (CMC) joint osteoarthritis is a common degenerative condition that affects up to 15 â% of the population older than 30 years. Poor readability of online health resources has been associated with misinformation, inappropriate care, incorrect self-treatment, worse health outcomes, and increased healthcare resource waste. This study aims to assess the readability and quality of online information regarding thumb carpometacarpal (CMC) joint replacement surgery. Methods: The terms "thumb joint replacement surgery", "thumb carpometacarpal joint replacement surgery", "thumb cmc joint replacement surgery", "thumb arthroplasty", "thumb carpometacarpal arthroplasty", and "thumb cmc arthroplasty" were searched in Google and Bing. Readability was determined using the Flesch Reading Ease Score (FRES) and the Flesch-Kincaid Reading Grade Level (FKGL). FRES >65 or a grade level score of sixth grade and under was considered acceptable. Quality was assessed using the Patient Education Materials Assessment Tool (PEMAT) and a modified DISCERN tool. PEMAT scores below 70 were considered poorly understandable and poorly actionable. Results: A total of 34 websites underwent qualitative analysis. The average FRES was 54.60 â± â7.91 (range 30.30-67.80). Only 3 (8.82 â%) websites had a FRES score >65. The average FKGL score was 8.19 â± â1.80 (range 5.60-12.90). Only 3 (8.82 â%) websites were written at or below a sixth-grade level. The average PEMAT percentage score for understandability and actionability was 76.82 â± â9.43 (range 61.54-93.75) and 36.18 â± â24.12 (range 0.00-60.00) respectively. Although 22 (64.71 â%) of websites met the acceptable standard of 70 â% for understandability, none of the websites met the acceptable standard of 70 â% for actionability. The average total DISCERN score was 32.00 â± â4.29 (range 24.00-42.00). Conclusions: Most websites reviewed were written above recommended reading levels. Most showed acceptable understandability but none showed acceptable actionability. To avoid the negative outcomes of poor patient understanding of online resources, providers of these resources should optimise accessibility to the average reader by using simple words, avoiding jargon, and analysing texts with readability software before publishing the materials online. Websites should also utilise visual aids and provide clearer pre-operative and post-operative instructions.
RESUMEN
Introduction Osteoarthritis (OA) is an age-related degenerative joint disease. There is a 25% risk of symptomatic hip OA in patients who live up to 85 years of age. It can impair a person's daily activities and increase their reliance on healthcare services. It is primarily managed with education, weight loss and exercise, supplemented with pharmacological interventions. Poor health literacy is associated with negative treatment outcomes and patient dissatisfaction. A literature search found there are no previously published studies examining the readability of online information about hip OA. Objectives To assess the readability of healthcare websites regarding hip OA. Methods The terms "hip pain", "hip osteoarthritis", "hip arthritis", and "hip OA" were searched on Google and Bing. Of 240 websites initially considered, 74 unique websites underwent evaluation using the WebFX online readability software (WebFX®, Harrisburg, USA). Readability was determined using the Flesch Reading Ease Score (FRES), Flesch-Kincaid Reading Grade Level (FKGL), Gunning Fog Index (GFI), Simple Measure of Gobbledygook (SMOG), Coleman-Liau Index (CLI), and Automated Readability Index (ARI). In line with recommended guidelines and previous studies, FRES >65 or a grade level score of sixth grade and under was considered acceptable. Results The average FRES was 56.74±8.18 (range 29.5-79.4). Only nine (12.16%) websites had a FRES score >65. The average FKGL score was 7.62±1.69 (range 4.2-12.9). Only seven (9.46%) websites were written at or below a sixth-grade level according to the FKGL score. The average GFI score was 9.20±2.09 (range 5.6-16.5). Only one (1.35%) website was written at or below a sixth-grade level according to the GFI score. The average SMOG score was 7.29±1.41 (range 5.4-12.0). Only eight (10.81%) websites were written at or below a sixth-grade level according to the SMOG score. The average CLI score was 13.86±1.75 (range 9.6-19.7). All 36 websites were written above a sixth-grade level according to the CLI score. The average ARI score was 6.91±2.06 (range 3.1-14.0). Twenty-eight (37.84%) websites were written at or below a sixth-grade level according to the ARI score. One-sample t-tests showed that FRES (p<0.001, CI -10.2 to -6.37), FKGL (p<0.001, CI 1.23 to 2.01), GFI (p<0.001, CI 2.72 to 3.69), SMOG (p<0.001, CI 0.97 to 1.62), CLI (p<0.001, CI 7.46 to 8.27), and ARI (p<0.001, CI 0.43 to 1.39) scores were significantly different from the accepted standard. One-way analysis of variance (ANOVA) testing of FRES scores (p=0.009) and CLI scores (p=0.009) showed a significant difference between categories. Post hoc testing showed a significant difference between academic and non-profit categories for FRES scores (p=0.010, CI -15.17 to -1.47) and CLI scores (p=0.008, CI 0.35 to 3.29). Conclusions Most websites regarding hip OA are written above recommended reading levels, hence exceeding the comprehension levels of the average patient. Readability of these resources must be improved to improve patient access to online healthcare information which can lead to improved patient understanding of their own condition and treatment outcomes.
RESUMEN
Linburg-Comstock syndrome is an acquired symptomatic restrictive thumb index finger flexor tenosynovitis involving a hypertrophic tenosynovium between flexor pollicis longus and flexor digitorum profundus. Patients may report synkinetic movement of the thumb and index finger, pain and swelling. We present the case of a woman in her 80s who presented with painless Linburg-Comstock syndrome after a trapeziectomy 4 months earlier for trapeziometacarpal arthritis. A literature review of PubMed-indexed case reports found that Linburg-Comstock syndrome has never been described in a post-trapeziectomy patient. This unusual presentation that arose as a side effect of hand surgery remains unreported in the literature. We present this unique complication as the first such case in the world. This case report is a valuable addition to the existing knowledge on the complications of trapeziectomy surgery.

Total hip arthroplasty (THA) is often regarded as one of the most successful surgical techniques developed in the twenty-first century. However, it is associated with complications such as prosthetic instability, dislocations, or infections. Dual-mobility (DM) implants have been developed with the goal of reducing the incidence of dislocations by increasing the femoral head-neck ratio, maximising hip stability, and improving the range of motion (ROM) before impingement and dislocation. This systematic review aims to comprehensively compare the safety and efficacy of DM versus fixed-bearing (FB) implants in primary THA patients. A comprehensive search strategy of PubMed, Embase, Scopus, and Web of Science Core Collection databases was executed to identify pertinent literature comparing DM and FB implants in THAs. Eligible studies underwent independent screening, and data were systematically extracted. The analysis employed pooled risk ratios (RR) for dichotomous outcomes and mean differences (MD) for continuous variables, each accompanied by their respective 95% confidence intervals (CI). Our systematic review and meta-analysis included nine studies encompassing 22,277 patients. The DM group had a significantly reduced incidence of dislocations compared to the FB group (RR 0.25, 95%CI [0.13, 0.47]; p-value <0.0001) and a significantly shorter length of stay (MD -9.92, 95%CI [-15.53, -4.32]; p-value = 0.0005). The FB group, however, had a significantly shorter operative time compared to the DM group (MD 10.41, 95%CI [7.64, 13.17]; p-value < 0.00001). We did not identify any significant statistical differences between the DM and FB groups regarding patient-reported outcome measures, the incidence of all-cause readmissions, the incidence of peri-prosthetic fractures, the incidence of infections, or the incidence of groyne pain.
RESUMEN
Weber Type B fractures often arise from external rotation with the foot supinated or pronated. Altered tibiofibular joint kinematics in Weber B fractures are responsible for syndesmotic damage seen in Weber B fractures. Weber B fractures are managed using open reduction and internal fixation if displaced. The syndesmosis is injured in up to 40% of cases resulting in an unstable injury with a syndesmotic diastasis. This systematic review aimed to evaluate the current literature on syndesmotic fixation in Weber B fractures, assess the outcomes and complications of syndesmotic fixation and assess the necessity of syndesmotic fixation in Weber B fractures. A search was carried out on the EMBASE, PubMed and CINAHL databases and eight studies assessing the outcomes of syndesmotic fixations versus no syndesmotic fixation with 292 Weber B ankle fractures were included in this systematic review. Results showed significant heterogeneity so a narrative review was conducted. Results of these studies showed that functional, radiological, and quality-of-life outcomes and incidences of post-traumatic osteoarthritis in patients with syndesmotic screws were similar to those of patients not managed with syndesmotic screws. Only one favoured syndesmotic fixation in all cases of diastasis. As such, syndesmotic fixation with screws may not be necessary in the management of Weber B fractures. Screws are also associated with breakage, loosening, local irritation and infections. Suture button devices and antiglide fixation techniques appear to be valid alternatives to syndesmotic screws. It was found that there was no need for routine hardware removal unless the hardware was causing significant side effects for the patient.

Investigating the genetic factors influencing human birth weight may lead to biological insights into fetal growth and long-term health. Genome-wide association studies of birth weight have highlighted associated variants in more than 200 regions of the genome, but the causal genes are mostly unknown. Rare genetic variants with robust evidence of association are more likely to point to causal genes, but to date, only a few rare variants are known to influence birth weight. We aimed to identify genes that harbour rare variants that impact birth weight when carried by either the fetus or the mother, by analysing whole exome sequence data in UK Biobank participants. We annotated rare (minor allele frequency <0.1%) protein-truncating or high impact missense variants on whole exome sequence data in up to 234,675 participants with data on their own birth weight (fetal variants), and up to 181,883 mothers who reported the birth weight of their first child (maternal variants). Variants within each gene were collapsed to perform gene burden tests and for each associated gene, we compared the observed fetal and maternal effects. We identified 8 genes with evidence of rare fetal variant effects on birth weight, of which 2 also showed maternal effects. One additional gene showed evidence of maternal effects only. We observed 10/11 directionally concordant associations in an independent sample of up to 45,622 individuals (sign test P=0.01). Of the genes identified, IGF1R and PAPPA2 (fetal and maternal-acting) have known roles in insulin-like growth factor bioavailability and signalling. PPARG, INHBE and ACVR1C (all fetal-acting) have known roles in adipose tissue regulation and rare variants in the latter two also showed associations with favourable adiposity patterns in adults. We highlight the dual role of PPARG in both adipocyte differentiation and placental angiogenesis. NOS3, NRK, and ADAMTS8 (fetal and maternal-acting) have been implicated in both placental function and hypertension. Analysis of rare coding variants has identified regulators of fetal adipose tissue and fetoplacental angiogenesis as determinants of birth weight, as well as further evidence for the role of insulin-like growth factors.
RESUMEN
Apert syndrome is a rare inherited syndrome characterised by craniosynostosis, midface hypoplasia, and syndactyly of the hands and feet. Syndactyly of the hands is categorised into three types with varying severity, requiring a diverse range of surgical techniques to produce good functional and aesthetic outcomes. The best age to initiate hand reconstruction is between three and 12 months. We present a case of a three-year-old boy with type III syndactyly who first presented at a volunteer outreach surgical campus in Pemba, Zanzibar. A three-stage bilateral hand reconstruction was initiated to sequentially create the first, fourth, and second web spaces. Postoperative healing was uneventful. He underwent a hand rehabilitation program and demonstrated good functional outcomes, being able to attend school, hold a pen, and write by seven years old. A literature review revealed that the best age to initiate hand reconstruction or the best surgical technique to use has yet to be agreed upon. It is agreed that the diverse symptoms of Apert syndrome make it difficult to manage, requiring multidisciplinary collaboration to provide physical and emotional benefits to patients and families.
RESUMEN
Giant cell tumours (GCTs) of the bone often arise in the long bones while occurrence in smaller bones of the hand and feet is very rare. We report a case of GCT in the talus of a 17-year-old male who presented with a six-month history of worsening pain in his left ankle and loss of function, reducing his ability to walk and participate in sports. Radiographs of the ankle showed bony overgrowth on the head and neck of the talus with cortical breaching. MRI revealed possible extension into soft tissue and bone marrow oedema. CT scan also revealed an aggressive lytic lesion at the head and neck of the talus. He was managed with intralesional curettage and autologous bone grafting with bone harvested from the left knee. There was no evidence of recurrence at the six-month follow-up and the patient was able to walk freely. In conclusion, GCTs of the talus tend to occur in younger and healthier patients and have disastrous consequences if they persist, recur, or metastasize. Given the severe negative impact that GCTs have on a patient's quality of life, they must be ruled out when investigating any ankle pain or reduced mobility. Current treatment options have produced consistently positive results while novel therapies that enable a faster return to weight bearing and reduce recurrence appear promising.
RESUMEN
STUDY DESIGN: A magnetic resonance imaging study of human cadaver spines. OBJECTIVE: To investigate associations between cartilage endplate (CEP) thickness and disc degeneration. SUMMARY OF BACKGROUND DATA: Damage to the CEP is associated with spinal injury and back pain. However, CEP morphology and its association with disc degeneration have not been well characterized. METHODS: Ten lumbar motion segments with varying degrees of disc degeneration were harvested from six cadaveric spines and scanned with magnetic resonance imaging in the sagittal plane using a T2-weighted two-dimensional (2D) sequence, a three-dimensional (3D) ultrashort echo-time (UTE) imaging sequence, and a 3D T1ρ mapping sequence. CEP thicknesses were calculated from 3D UTE image data using a custom, automated algorithm, and these values were validated against histology measurements. Pfirrmann grades and T1ρ values in the disc were assessed and correlated with CEP thickness. RESULTS: The mean CEP thickness calculated from UTE images was 0.74â±â0.04âmm. Statistical comparisons between histology and UTE-derived measurements of CEP thickness showed significant agreement, with the mean difference not significantly different from zero (Pâ=â0.32). Within-disc variation of T1ρ (standard deviation) was significantly lower for Pfirrmann grade 4 than Pfirrmann grade 3 (Pâ<â0.05). Within-disc variation of T1ρ and adjacent CEP thickness heterogeneity (coefficient of variation) had a significant negative correlation (râ=â-0.65, Pâ=â0.04). The standard deviation of T1ρand the mean CEP thickness showed a moderate positive correlation (râ=â0.40, Pâ=â0.26). CONCLUSION: This study demonstrates that quantitative measurements of CEP thickness measured from UTE magnetic resonance imaging are associated with disc degeneration. Our results suggest that variability in CEP thickness and T1ρ, rather than their mean values, may serve as valuable diagnostic markers for disc degeneration. LEVEL OF EVIDENCE: N/A.
