Pediatric wrist fractures: variations in management across countries. An evidence-based summary of evidence.

INTRODUCTION: Fractures of the distal radius are common in pediatric population, with considerable variation in the management of pediatric wrist fractures across different countries. It is crucial to consider the different approaches to conservative management and surgical intervention. The decision on the appropriate treatment method often depends on the type and severity of the fracture, as well as the available healthcare resources and expertise in each country. This article tries to identify these variations, so the various healthcare systems can work toward implementing best practices in the management of pediatric wrist fractures on a global scale. SOURCE OF DATA: Published peer-reviewed articles identified in electronic databases, including PubMed Scopus and Google Scholar. AREAS OF AGREEMENT: The management of pediatric wrist fractures can differ significantly among countries given the high variability in healthcare resources and cultural practices. AREAS OF CONTROVERSY: The management of pediatric wrist fractures can be challenging in certain countries, especially in developing regions with limited resources. GROWING POINTS: Challenges such as long therapeutic delays, lack of appropriate anesthesia, and the absence of fluoroscopy can complicate the treatment process. Randomized controlled clinical trials (RCTs) are vital in providing high-quality evidence to guide clinical decision-making, especially in the field of pediatric wrist fractures. AREAS TIMELY FOR DEVELOPING RESEARCH: Efforts to support and prioritize the conduct and dissemination of RCTs in pediatric wrist fracture management can ultimately lead to more consistent, effective, and evidence-based care for children with wrist fractures worldwide.

Wharton's jelly and osteoarthritis of the knee.

INTRODUCTION: The existing treatment modalities for knee osteoarthritis (OA) do not actually address the pathology. Biological therapies, including those using material derived from perinatal tissues, represent a ground-breaking approach to alleviating the symptoms of OA of the knee. SOURCE OF DATA: Current scientific literature published in PubMed (MEDLINE), Embase and Scopus databases. Trials registered in various clinical trial databases. AREAS OF AGREEMENT: Perinatal tissues including Wharton's jelly (WJ) and associated mesenchymal stem cells (MSCs) can be used for the management of knee OA. AREAS OF CONTROVERSY: The efficacy of WJ and associated MSCs in the management of knee OA is still controversial. GROWING POINTS: The use of WJ and associated MSCs in the management of knee OA is safe and appears to be effective. AREAS TIMELY FOR DEVELOPING RESEARCH: The present published evidence suggests that WJ tissue and associated MSCs offer an encouraging alternative for the management of knee OA. The published in vitro, preclinical and clinical investigations demonstrate the therapeutic potential of WJ and promote further research in this field to provide symptomatic relief to patients suffering from OA, aiming also to regenerate the osteoarthritic hyaline cartilage, with disease-modifying effects. Future adequately powered randomized controlled trials should be undertaken to establish whether WJ is helpful in the management of OA of the knee.

Bone-patellar tendon-bone, hamstring, and quadriceps tendon autografts for anterior cruciate ligament reconstruction in skeletally immature patients: a systematic review.

INTRODUCTION: Historically, anterior cruciate ligament (ACL) ruptures in the paediatric age group were managed conservatively with bracing, casting, activity modification, and physical therapy. However, most of these patients had to reduce their sports activities, and secondary damages to the affected knee were prevalent. SOURCE OF DATA: Published scientific literature in Embase, Web of Science, PubMed, and Google Scholar databases. AREAS OF AGREEMENT: ACL reconstruction in children with open physes patients is debated. Any damage to the physes around the knee could lead to growth abnormalities and axial deviation of the knee. AREAS OF CONTROVERSY: Different grafts are available and suitable for ACL reconstruction in skeletally immature patients; however, which graft performs better remains unclear. GROWING POINTS: This systematic review compared bone-patellar tendon-bone (BPTB), hamstring tendon (HT), and quadriceps tendon (QT) autografts for ACL reconstruction in skeletally immature patients. The joint laxity, Patient-reported outcome measures (PROMs), return to sport, and complications were compared. AREAS TIMELY FOR DEVELOPING RESEARCH: In skeletally immature patients, HT, BPTB, and QT autografts for ACL reconstruction yielded good outcomes. Comparative studies are strongly required to establish the most suitable autograft.

Pharmacological management of secondary chronic spinal cord injury: a systematic review.

INTRODUCTION: Spinal cord injury (SCI) may bring lifelong consequences for affected patients and a high financial burden to the health care system. SOURCE OF DATA: Published peer-reviewed scientific articles identified from EMBASE, Google Scholar, PubMed and Scopus. AREAS OF AGREEMENT: Surgery and blood pressure management are the main targets in acute SCI to avoid secondary damage. AREAS OF CONTROVERSY: The management of secondary chronic SCI is challenging, with unpredictable outcomes. GROWING POINTS: Given the lack of consensus on pharmacological therapy for acute and secondary chronic SCI, the present study analyses the currently available drugs and treatment options to manage secondary chronic SCI. AREAS TIMELY FOR DEVELOPING RESEARCH: Different approaches exist for the pharmacological management of secondary chronic SCI. One of the most investigated drugs, 4-aminopyridine, improves central motor conduction and shows improvement in neurological signs. Positive results in different areas have been observed in patients receiving the anti-spastic drugs tizanidine and baclofen or Granulocyte colony-stimulating factor. Growth hormone showed only minimal or no significant effects, and the therapy of secondary chronic SCI with riluzole has been poorly researched to date.

Highest oxygen consumption prediction: introducing variable theoretical proportional factors for different sports.

PURPOSE: The use of a fixed theoretical-proportional-factor (TPF15) is one of the indirect highest-oxygen-consumptions (HOC) assessment methods, but it may not accurately reflect the physiological differences across various sports (cycling-triathlon-running-football-multisport). The aim of this study is to evaluate the variability of TPF across different sports, proposing a series of sport-specific new TPF values for more accurate HOC estimation. METHODS: A sample of 340 adults (26.01 ± 7.18 years) performed a maximal-incremental-test using sport-specific-ergometers. HOC was considered for cycling  V ˙ O 2peak , whereas for the other investigated sports it was considered V ˙ O 2max . HOC was directly measured using a gas-analyzer, and TPF values were calculated using heart rate (HR): the ratio of HRmax/HRrest multiplied for the measured values of HOC. A one-way ANOVA was used to measure differences and Bland-Altman plots were constructed to compare predicted and actual  V ˙ O 2max / V ˙ O 2peak . RESULTS: Actual HOC was significantly greater than those predicted by the fixed TPF15 (P < 0.001). Sport-specific new TPF values ranged from 16.55 in multisport to 20.15 in cycling, consistently exceeding the old fixed TPF15, and predicting therefore better HOC. The new TPF exhibited a closer agreement with the directly measured V ˙ O 2max / V ˙ O 2peak  compared to the TPF15. Furthermore, the new TPF reduced the typical-measurement-error (14.94-17.78%) compared to TPF15 (15.63-24.13%). CONCLUSION: This study suggests that new TPF values predict V ˙ O 2max / V ˙ O 2peak  with higher accuracy compared to the traditional method. The use of HRmax and HRrest values allows to customize training programs for different athletes. Future research should focus on validating these findings across larger populations of athletes.

TENDINopathy Severity assessment-Achilles (TENDINS-A): evaluation of reliability and validity in accordance with COSMIN recommendations.

OBJECTIVE: To evaluate the construct validity (structural validity and hypothesis testing), reliability (test-retest reliability, measurement error and internal consistency) and minimal important change (MIC) of the 13-item TENDINopathy Severity assessment-Achilles (TENDINS-A). METHODS: Participants with Achilles pain completed an online survey including: demographics, TENDINS-A, Foot and Ankle Outcome Score (FAOS) and Victorian Institute of Sport Assessment-Achilles (VISA-A). Exploratory factor analysis (EFA) assessed dimensionality. Confirmatory factor analysis (CFA) assessed structural validity (root mean square error of approximation (RMSEA); Comparative Fit Index (CFI); Tucker-Lewis Index (TLI); standardised root measure square (SRMS)). Correlations between TENDINS-A and the FAOS or VISA-A assessed hypothesis testing. Intraclass correlation (ICC) assessed test-retest reliability. Cronbach's alpha assessed internal consistency. SE of the measurement (SEM) assessed measurement error. A distribution-based approach assessed MIC. RESULTS: 79 participants (51% female) with a mean (SD) age=42.6 (13.0) years, height=175.0 (11.7) cm and body mass=82.0 (19.1) kg were included. EFA identified three meaningful factors, proposed as pain, symptoms and function. The best model identified using CFA for TENDINS-A had structural validity (RMSEA=0.101, CFI=0.959, TLI=0.947, SRMS=0.068), which included three factors (pain, symptoms and function), but excluded three items from the original TENDINS-A. TENDINS-A exhibited moderate positive correlation with FAOS (r=0.598, p<0.001) and a moderate negative correlation with VISA-A (r=-0.639, p<0.001). Reliability of the TENDINS-A was excellent (ICC=0.930; Cronbach's α=0.808; SEM=6.54 units), with an MIC of 12 units. CONCLUSIONS: Our evaluation of the revised 10-item TENDINS-A determined it has construct validity and excellent reliability, compared with the VISA-A and FAOS which lack content and construct validity. The TENDINS-A is recommended as the preferred patient-reported outcome measure to assess disability in people with Achilles tendinopathy.

ICON 2023: International Scientific Tendinopathy Symposium Consensus - the core outcome set for Achilles tendinopathy (COS-AT) using a systematic review and a Delphi study of professional participants and patients.

To develop a core outcome set for Achilles tendinopathy (COS-AT) for use in clinical trials we performed a five-step process including (1) a systematic review of available outcome measurement instruments, (2) an online survey on truth and feasibility of the available measurement instruments, (3) an assessment of the methodological quality of the selected outcome measurement instruments, (4) an online survey on the outcome measurement instruments as COS and (5) a consensus in-person meeting. Both surveys were completed by healthcare professionals and patients. The Outcome Measures in Rheumatology guidelines with a 70% threshold for consensus were followed. We identified 233 different outcome measurement instruments from 307 included studies; 177 were mapped within the International Scientific Tendinopathy Symposium Consensus core domains. 31 participants (12 patients) completed the first online survey (response rate 94%). 22/177 (12%) outcome measurement instruments were deemed truthful and feasible and their measurement properties were evaluated. 29 participants (12 patients) completed the second online survey (response rate 88%) and three outcome measurement instruments were endorsed: the Victorian Institute of Sports Assessment-Achilles questionnaire, the single-leg heel rise test and evaluating pain after activity using a Visual Analogue Scale (VAS, 0-10). 12 participants (1 patient) attended the final consensus meeting, and 1 additional outcome measurement instrument was endorsed: evaluating pain during activity/loading using a VAS (0-10). It is recommended that the identified COS-AT will be used in future clinical trials evaluating the effectiveness of an intervention. This will facilitate comparing outcomes of intervention strategies, data pooling and further progression of knowledge about AT. As COS-AT is implemented, further evidence on measurement properties of included measures and new outcome measurement instruments should lead to its review and refinement.

Shoulder balloon spacer for massive irreparable rotator cuff tears results in significant improvements.

PURPOSE: The aim of the present study was to assess the effectiveness of balloon implantation in patients with irreparable supraspinatus tears alone or in combination with other rotator cuff (RC) tendon tears and the effect of several covariables, such as age, gender, status of the long head biceps, with or without tendon repair and regardless the number of tendon involved. METHODS: Patients enrolled from 'San Carlo' Hospital of Potenza (Italy, IT), from January 2012 to September 2014, underwent arthroscopic implantation of shoulder balloon by a single surgeon, and followed for 3 years. The American Shoulder and Elbow Surgeons (ASES) and Constant score (CS) were administered pre-, post-operatively at 12 months, and then annually. Patients were classified on the basis of the number of tendons involved in the tears and treatment performed, considering the reparability of the tendons themselves. Gleno-humeral joint osteoarthrosis (OA) was evaluated through shoulder radiographs and classified according to the Samilson-Prieto classification, at the first examination and at the final follow-up. Statistical improvements were evaluated using a variance model (least-squares means) and a T distribution test for the evaluation between different treatment groups. RESULTS: A total of 61 procedures were performed, and eight patients were lost during follow-up. The mean baseline CS was 30.2 ± 15.4 with statistically significant improvement, respectively, at 1-, 2- and 3-year follow-up to 69.3 ± 4.2, 74.6 ± 3.6 and 69.7 ± 5.1 respectively. ASES score at baseline was 22.5 ± 10.9, with a statistically significant improvement to 69.7 ± 9.2, 68 ± 17.8 and 71.2 ± 16.6 at 1-, 2- and 3-year follow-up, respectively. Tenotomy or absence of long head biceps at presentation did not influence results (n.s.), with no difference according to gender and age. At final follow-up, 24 patients (43.9%) showed progression of glenohumeral OA. One patient required secondary surgery for shoulder replacement after 18 months for persistent pain and one patient required implant removal following post-operative laser treatment. CONCLUSION: Arthroscopic rotator cuff tears repair with subacromial spacer balloon implantation showed statistically significant clinical and functional improvement at 3-year follow-up. Patients treated with combined partial repair and subacromial spacer balloon implantation experienced good results independent of gender, age, type of tear and long-head biceps tendon status. The risks related to this procedure appear to be minimal. LEVEL OF EVIDENCE: Level IV.

Non-surgical management of acute proximal hamstring avulsions can produce clinically acceptable results.

PURPOSE: To evaluate the mid-term clinical outcomes for the non-surgical and surgical management of acute proximal hamstring avulsions. METHODS: Sixty physically active individuals were offered surgical or non-surgical management for their proximal hamstring avulsion injuries. Distal retraction was defined as greater than 2 cm. Primary outcome measures were the Victorian Institute of sport assessment-proximal hamstring tendons (VISA-H) and functional assessment scale for acute hamstring injuries (FASH). Secondary outcome measures included palpable gap (cm), return to sport (RTS) and the ability to perform Nordic hamstring curls. Outcome variables were adjusted in regression models for gender, age, and treatment. RESULTS: Thirty-one patients elected to undertake non-surgical management, and 29 chose surgery with a mean follow-up of 34.8 ± 8.7 and 34.9 ± 7.0 months, respectively. The mean VISA-H for the non-surgical and surgical groups were 87.3 ± 3.4 and 87.9 ± 4.1 (n.s.), respectively. The mean FASH for the non-surgical group was 89.3 ± 2.4 and 88 ± 3.6 for the surgical group (n.s.). This was consistent after adjusting for confounders. The mean gap for the non-surgical group was 4.5 ± 1.09 and 4.9 ± 1.19 cm for the surgical group (n.s.). No significant differences were found in the abilities to perform Nordic hamstring curls (n.s.). Both groups achieved comparable RTS rates (n.s.). On average, the non-surgical group achieved RTS at 5.5 ± 1.2 months post-injury, whereas the surgical group was at 5.7 ± 0.7 months (n.s.). CONCLUSION: Physically active individuals with acute proximal hamstring avulsions and distal retraction of the tendon stump can be managed non-surgically, achieving similar functional levels and RTS compared to patients treated surgically. LEVEL OF EVIDENCE: Level III.

Long head of biceps tendon augmentation for massive rotator cuff tears improves clinical results regardless of the number of tendons involved.

PURPOSE: Management of massive rotator cuff tears (MRCTs) remains debated, and various arthroscopic and open techniques have been described for their management. Nevertheless, the optimal strategy remains unclear. The present study evaluated the clinical results in patients managed arthroscopically for MRCTs augmented with the long head biceps tendon (LHBT) at a minimum 1-year follow-up, considering different type of tears, demographic data and number of torn tendons. METHODS: Patients treated in a secondary referral centre from January 2021 to April 2022 were enroled prospectively. Inclusion criteria were pain, inability to fully elevate the affected shoulder, irreparable tears and active and motivated patients. All patients were managed within 2 months from diagnosis in a single centre by the same surgeons. Preoperative shoulder radiographs and magnetic resonance imaging (MRI) were collected, and clinical assessment was also performed using the Numerical analogue scale (NAS), Constant score (CS) American Shoulder and Elbow Surgeons Shoulder Score (ASES). Tissue retraction and tendon fatty infiltration were evaluated using Patte and Fuchs scale, respectively. Clinical assessment was performed using the same scales at 3-6 months and 1-year follow-up. RESULTS: A total of 55 patients (31 female and 24 male) with a mean age of 60 ± 7.1 years were enroled for a mean follow-up of 18.2 ± 4.3 months. The mean preoperative NAS was 7.8 ± 0.6, CS was 20.5 ± 7.6 and ASES was 22.6 ± 9.2, increasing, respectively, to 0.3 ± 0.6, 91.5 ± 6.9 and 94.2 ± 6.7. No adverse side effects (infection, rejection, allergy) were reported during the study period. All patients were evaluated after surgery at 3 and 6 months and 1 year with statistically significant improvement for each score at the first and last follow-up (p < 0.05). CONCLUSIONS: The use of LHBT augmentation in patients with MRCTs in appropriately selected patients is safe and effective and can lead to pain relief and acceptable clinical outcomes. Furthermore, its use carries low donor site morbidity and is cost effective. Comparative studies, including randomised controlled trials, with other proposed techniques are needed to confirm these findings. LEVEL OF EVIDENCE: Level IV.

Anterior cruciate ligament reconstruction in skeletally immature patients is effective: A systematic review.

PURPOSE: The present study evaluated the outcomes of anterior cruciate ligament (ACL) reconstruction in children with open physes. The outcomes of interest were to compare the increase in joint laxity and PROMs from baseline to the last follow-up, the rate and features of the return to sport and the rate of complications. METHODS: This study was conducted according to the 2020 PRISMA guidelines. In October 2023, the following databases were accessed: PubMed, Web of Science, Google Scholar and Embase. All the clinical studies investigating ACL reconstruction in skeletally immature patients were accessed. Only articles which clearly stated that surgeries were conducted in children with open physis were eligible. RESULTS: Data from 53 studies (1691 procedures) were collected. 35% (597 out of 1691 patients) were women. The mean length of the follow-up was 44.7 ± 31.3 months. The mean age of the patients was 12.7 ± 1.1 years old. All PROMs significantly improved from the baseline values to those at the last follow-up. The mean time to return to sport was 8.3 ± 1.9 months. 89% (690 out of 771 patients) returned to sports, 15% (109 out of 721 patients) reduced their level of sports activity or league, and 84% (651 out of 771 patients) returned to their previous level of sport. 9% (112 out of 1213) of patients experienced re-tear of the reconstructed ACL, and 11% (75 out of 660) of patients underwent a further ACL reoperation. No patients (0 out of 83) demonstrated increased laxity at the last follow-up, and persistent sensation of instability was reported by 5% (11 out of 235) of patients. CONCLUSION: ACL reconstruction in skeletally immature patients is effective and safe, and is associated with fast recovery and a high rate of return to sport. LEVEL OF EVIDENCE: Level IV.

Fibrin Scaffolds Perfused with Transforming Growth Factor-ß1 as an In Vitro Model to Study Healthy and Tendinopathic Human Tendon Stem/Progenitor Cells.

A limited understanding of tendon cell biology in healthy and pathological conditions has impeded the development of effective treatments, necessitating in vitro biomimetic models for studying tendon events. We established a dynamic culture using fibrin scaffolds, bioengineered with tendon stem/progenitor cells (hTSPCs) from healthy or diseased human biopsies and perfused with 20 ng/mL of human transforming growth factor-ß1 for 21 days. Both cell types showed long-term viability and upregulated Scleraxis (SCX-A) and Tenomodulin (TNMD) gene expressions, indicating tenogenic activity. However, diseased hTSPCs underexpressed collagen type I and III (COL1A1 and COL3A1) genes and exhibited lower SCX-A and TNMD protein levels, but increased type I collagen production, with a type I/type III collagen ratio > 1.5 by day 14, matching healthy cells. Diseased hTSPCs also showed constant high levels of pro-inflammatory cytokines, such as IL-8 and IL-6. This biomimetic environment is a valuable tool for studying tenogenic and inflammatory events in healthy and diseased tendon cells and identifying new therapeutic targets.

Demographic characteristics influencing the stem subsidence in total hip arthroplasty: an imaging study.

INTRODUCTION: The present study evaluated whether patient demographic characteristics influence the subsidence of the stem in total hip arthroplasty (THA). The following characteristics were evaluated: age, height, weight, and sex. The association between the time elapsed from the THA implantation and the amount of stem subsidence was also investigated. METHODS: The records of patients who underwent THA in the period between 2016 and 2023 were accessed. All patients underwent two-staged bilateral THA using cementless DePuy collarless Corail (DePuy Synthes, Raynham, MA, USA) stems. The following parameters were measured and compared to assess stem subsidence: distance from the proximal femur at the stem bone interface and the medial apex of the regular triangle built within the trochanter minor (point A); distance from the medial apex of the regular triangle built within the trochanter minor and the distal portion of the femoral stem (point B). RESULTS: Overall, 294 patients were included. 62% (182 of 294 patients) were women. 45% (134 of 296 THAs) were on the right side. The mean age was 64.9 ± 10.4 years. The mean BMI was 28.3 ± 5.1 kg/m2. The mean length of the follow-up was 14.4 ± 11.0 months. The mean subsidence in point A was 2.1 mm (P < 0.0001), and that in point B was 3.1 mm (P < 0.0001). There was evidence of a weak positive association between patient weight (P < 0.0001), age (P = 0.03), follow-up (P = 0.002) and the amount of stem subsidence. Patient height did not demonstrate any association with the amount of stem subsidence (P = 0.07). There was no difference in stem subsidence between women and men (P = 0.9). CONCLUSION: Stem subsidence in THA using cementless DePuy collarless Corail implants is approximately 2.6 mm after 14.4 months. Greater patient weight, age, and longer time elapsed from THA implantation were associated with greater stem subsidence. Patient height and sex did not demonstrate any influence on the amount of stem subsidence. These results must be considered in light of the limitations of the present study.

Clinical relevance of patient-reported outcome measures in patients who have undergone total hip arthroplasty: a systematic review.

INTRODUCTION: In orthopaedic research, it is crucial to determine changes that are statistically significant and clinically meaningful. One approach to accomplish this is by calculating the Minimal Clinically Important Difference (MCID), the Clinically Important Differences (CID), the Minimum Detectable Change (MDC), the Minimal Important Change (MIC), and the Patient Acceptable Symptom State (PASS) values. These tools assist medical professionals in comprehending the patient's viewpoint, enabling them to establish treatment objectives that align with patients' desires and expectations. The present systematic review investigated the MCID, MIC, CID, MDC, and PASS of the most used PROMs to assess patients who have undergone THA. METHODS: This systematic review followed the 2020 PRISMA guidelines. Web of Science, Embase, and PubMed were accessed in March 2024 without time constraints or additional filters. All the clinical investigations which evaluated data tools (MCID, MIC, CID, MDC, and PASS) to assess the clinical relevance of PROMs in THA were accessed. Articles in Spanish, Italian, German, and English were eligible. Studies with levels of evidence I to III were eligible. RESULTS: Data from 100,824 patients were collected. All relevant demographic data were analysed and summarised. In addition, the MCID, MIC, CID, MDC and PASS of the COMI, HOOS, SF-36, OHS, Oxford-12, PROMIS-PF, SF-12, and WOMAC scores for THA were determined. CONCLUSION: Current evidence recommends to collect MCIDs based on anchors routinely. These values should be used as complementary tools to determine the clinical effectiveness of a treatment instead of solely relying on statistically significant improvements. LEVEL OF EVIDENCE: Level IV, systematic review and meta-analysis.

Better outcomes using suture button compared to screw fixation in talofibular syndesmotic injuries of the ankle: a level I evidence-based meta-analysis.

INTRODUCTION: The present meta-analysis evaluated current level I clinical trials which compared the use of a suture button (SB) versus syndesmotic screw (SS) fixation techniques for syndesmosis injuries of the ankle. The outcomes of interest were to compare patient-reported outcome measures (PROMs) and complications. It was hypothesised that SB might achieve better PROMs along with a lower rate of complications. METHODS: This study was conducted according to the 2020 PRISMA statement. In August 2023, PubMed, Web of Science, Google Scholar, and Embase were accessed. All the randomised controlled trials (RCTs) which compared SB versus SS fixation for syndesmosis injuries of the ankle were accessed. Data concerning the American Orthopaedic Foot & Ankle Society (AOFAS), and Olerud-Molander score (OMS) were collected at baseline and at last follow-up. Data on implant failure, implant removal, and joint malreduction were also retrieved. RESULTS: Data from seven RCTs (490 patients) were collected. 33% (161 of 490) were women. The mean length of the follow-up was 30.8 ± 27.4 months. The mean age of the patients was 41.1 ± 4.1 years. Between the two groups (SB and SS), comparability was found in the mean age, and men:women ratio. The SS group evidenced lower OMS (P = 0.0006) and lower AOFAS (P = 0.03). The SS group evidenced a greater rate of implant failure (P = 0.0003), implant removal (P = 0.0005), and malreduction (P = 0.04). CONCLUSION: Suture button fixation might perform better than the syndesmotic screw fixation in syndesmotic injuries of the ankle.

Percutaneous transverse pinning for metacarpal fractures: a clinical trial.

INTRODUCTION: Metacarpal fractures account for 25%-50% of all hand fractures and may negatively impact hand function and ability to work. Percutaneous transverse pinning of non-articular metacarpal fractures allows mobilisation immediately after the procedure. METHODS: Between March 2017 and February 2022, 56 patients undergoing percutaneous transverse pinning for unstable metacarpal fractures were prospectively recruited. We investigated surgical outcomes in terms of Patient-rated Wrist/Hand Evaluation (PRWHE) and pre-and post-operative radiographic evaluation. The Student t-test was used to compare the means of PRWHE values after surgery. Statistical significance was set at p < 0.05. RESULTS: The mean age was 40.21 ± 17.9 years (range of 16 to 86 years). The average operating time was 27.96 min. The mean follow-up period was 14.3 ± 6.4 months (from 2 to 41 months). The mean PRWHE score was 6.5 ± 1.8. None of the patients had clinically observable rotational deformities, and the functional outcomes were satisfactory. CONCLUSION: Percutaneous transverse pinning for non-articular metacarpal fractures restores excellent function, and imaging results are satisfactory. Further high-quality clinical trials are required to validate these results on a larger scale. LEVEL OF EVIDENCE: II, prospective cohort study.

Functional alignment in robotic-assisted total knee arthroplasty: a systematic review.

PURPOSE: The present study systematically reviewed current evidence on functional alignment (FA) in robotic total knee arthroplasty (TKA), discussing advantages and limitations, possible pitfalls, and prospects. METHODS: This study was conducted according to the 2020 PRISMA statement. In August 2023, the following databases were accessed: PubMed, Web of Science, Google Scholar, and Embase with no additional filters or time constraints. All the clinical studies investigating functional alignment in robotic TKA were accessed. Only studies published in peer-reviewed journals were considered. The risk of bias was evaluated following the guidelines in the Cochrane Handbook for Systematic Reviews of Interventions. Non-randomized controlled trials (non-RCTs) were evaluated using the Risk of Bias in Nonrandomised Studies of Interventions (NRSI) (ROBINS-I) tool. RESULTS: Data from 1198 patients (seven studies) were retrieved. The mean length of the follow-up was 17.1 ± 6.4 months. The mean age was 67.2 ± 5.4 years, and the mean BMI was 30.9 ± 2.7 kg/m2. CONCLUSION: FA might improve resection accuracy, implant alignment, and gap balancing in TKA, and additional high-quality clinical trials are necessary to properly establish the superiority of FA to other alignment techniques in TKA. Long-term clinical trials are needed to investigate the impact of FA on implant survivorship. LEVEL OF EVIDENCE: Level IV, systematic review and meta-analysis.

"Heterotopic ossification after total hip arthroplasty through direct anterior approach without a dedicated orthopaedic table or direct lateral approach: a quasi-randomized single-center study".

INTRODUCTION: Heterotopic ossifications (HO) are common after total hip arthroplasty (THA). The invasiveness of surgical approaches plays a relevant role in HO development. The aims of this study were to assess the development of HO 6 months after THA through direct lateral approach (DLA) or direct anterior approach (DAA) without a dedicated orthopaedic table and to assess the clinical impact of HO. METHODS: This is a single-center IRB-approved, quasi-randomized prospective cohort, observational imaging study. Fifty patients underwent primary THA through DLA and 50 through DAA. Age, sex, BMI and side of the affected hip were collected. At the 6 post-operative month the Harris Hip Score (HHS) and the presence of HO (scored through the Brooker classification system) were assessed. RESULTS: There was no significant difference in the demographic data between groups. Operative time was significantly higher in the DAA group (72 ± 10 min vs. 58 ± 8 min: p < 0.03). At 6 post-operative months the incidence of HO was 14% in the DAA group and 32% in the DLA group (p = 0.02). Severe HO (Brooker 3-4) were significantly more common in the DLA group (p = 0.04). There was no significant difference in the HHS of patients with HO between the DAA and DLA groups. There was no association between poorer clinical outcomes and the severity of HO. CONCLUSION: The DAA without a dedicated orthopaedic table is associated with a significant lower incidence of HO than the DLA 6 months after elective THA. Except for the surgical approach, no other factors correlated with the occurrence of HO. Even though a lower HHS was found with severe HO, the correlation between severity of HO and clinical outcomes did not reach statistical significance.

Spontaneous Resolution of Symptomatic Synovial Cysts of the Lumbar Spine: A Comprehensive Review with Two Illustrative Cases.

Although lumbar synovial cysts (LSCs) are frequently described in the literature, they are a relatively uncommon cause of low back and radicular leg pain. Furthermore, their spontaneous resolution is an even rarer event. The standard treatment of the lumbar synovial cyst is surgical excision. Spontaneous resolution in the literature is a sporadic event. In our experience, we have had two cases where the lumbar synovial cyst disappeared spontaneously. To date, only nine cases of spontaneous resolution of synovial cysts have been documented in the literature. In this discussion, we highlight a pathology that typically suggests surgical intervention, yet conservative treatment can be a viable alternative. We present two cases of large synovial cysts that were initially scheduled for surgery but ultimately resolved spontaneously without any treatment. While the spontaneous resolution of lumbar synovial cysts is extremely rare, conservative strategies are an option that should not be overlooked. Our cases contribute to the growing body of evidence on the spontaneous regression of symptomatic LSC, potentially enhancing the understanding of the disease's natural progression in the future.

EFAS Score - Validation of Danish Version by the Score Committee of the European Foot and Ankle Society (EFAS).

BACKGROUND: The Score Committee of the European Foot and Ankle Society (EFAS) developed, validated, and published the EFAS Score in 13 languages. Currently, the Danish version completed data acquisition and underwent further validation. METHODS: The data were collected pre-operatively and post-operatively at a minimum follow-up of 3 months and mean follow-up of 6 months. Item reduction, scale exploration, confirmatory analyses and responsiveness were executed using classical test theory and item response theory. RESULTS: The internal consistency was confirmed in the Danish version (Cronbach's Alpha 0.88). The Standard Error of Measurement (SEM) was 0.31 and is similar to other language versions. Between baseline and follow-up, 77.2% of patients showed an improvement on their EFAS score, with adequate responsiveness (effect size 1.05). CONCLUSIONS: The Danish EFAS Score version was successfully validated in patients with a wide variety of foot and ankle pathologies. All score versions are freely available at www.efas.net.
