BACKGROUND: Radial head fractures are the most common bony injury of the elbow in adults. The current literature does not agree on whether isolated stable type II radial head fractures should be treated operatively or nonoperatively. This review aims to determine the preferred treatment for Mason type II radial head fractures and compare the outcomes of conservative and surgical treatment.
METHODS: Our study used PRISMA guidelines and conducted a thorough search of multiple electronic databases, including PubMed, Cochrane, Embase, Web of Science, CNKI, and Wanfang databases, initially identifying 545 relevant publications on surgical and conservative treatment of Mason type II radial head fractures. The final search date for this study is July 7, 2024.Through a comprehensive meta-analysis, we evaluated several outcomes, including functional scores (DASH, OES, and MEPS scores), clinical outcomes (elbow flexion, elbow extension deficit, elbow pronation, and elbow supination), and complication rate (total complications and elbow pain). The mean difference (MD) was compared for continuous outcomes, and the odds ratios (ORs) were compared for categorical outcomes.
RESULTS: A total of 271 patients from 4 studies met the inclusion criteria. Among them, 142 patients received surgical treatment and 129 patients received non-surgical treatment. The study found no statistically significant differences between surgical and non-surgical treatments in DASH, OES, MEPS, elbow flexion, elbow extension impairment, and elbow pain. Compared with surgical treatment, non-surgical treatment was associated with greater elbow pronation (OR = -3.10, 95% CI = [-4.96, -1.25], P = 0.55, I2 = 0%) and a lower complication rate (OR = 5.54, 95% CI = [1.79, 17.14], P = 0.42, I2 = 0%).
CONCLUSIONS: Based on the current evidence, conservative management of isolated Mason II radial head fractures yields favorable therapeutic outcomes with a low incidence of complications.

UNASSIGNED: Non-operative management for pediatric blunt splenic injury is well established in high-income countries, leading to a low splenectomy rate in hemodynamically stable children. Splenectomy rate became a quality indicator for Trauma Center verification utilized by the American College of Surgeons Committee on Trauma. However, data on splenectomy rate in children from countries with different income levels, such as Brazil, remain limited. This study aimed to assess the post-traumatic splenectomy rate among Brazilian children over the past decade and the relation with local resources.
UNASSIGNED: Data on pediatric splenic injuries and splenectomies from 2008 to 2019, including patient age and admitting service (adult or pediatric), were obtained from FioCruz database, a public, free, cloud-based platform that offers extensive national health data. The regional numbers of pediatric surgeons, pediatric intensive care unit (PICU) beds, and computed tomography scanners were obtained from Brazilian national databases. A national analysis of splenectomy rate by year and service of admission and an analysis of splenectomy rate by the level of regional resources, the number of pediatric surgeons, PICU beds, and computed tomography scanners was performed.
UNASSIGNED: 4061 children were hospitalized with a splenic injury, and 2287 (51.8%) of them underwent splenectomy, unchanged over time. 76.8% were male and 23.1% female patients with splenic injury. Mean age was 11.61 years old. The odds of splenectomy was 14.77 times higher for pediatric patients admitted under adult surgical service compared to pediatric service (OR = 14.77, 95% CI 11.75-18.56, p < 0.0001). The overall increase in pediatric surgeons, PICU beds, and CT scanner availability did not correspond with changes in splenectomy rate.
UNASSIGNED: The post-traumatic splenectomy rate among Brazilian children is high, far exceeding that of high-income countries. Increased regional pediatric resources did not correspond to a decrease in splenectomy rate. Further research is essential to understand Brazil\'s barriers to adopting non-operative management for pediatric splenic injuries.
UNASSIGNED: This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.

UNASSIGNED: Proximal tibiofibular joint (PTFJ) subluxations are rare and can occur following trauma or sporting events. Idiopathic PTFJ subluxations are more common in females and in patients with generalized ligament laxity. The proper history and clinical examination together with imaging can help in establishing the diagnosis in the majority of cases.
UNASSIGNED: We report a rare case of bilateral subluxation of PTFJ and describe the detailed clinical features and magnetic resonance imaging findings. The patient was managed conservatively with good results.
UNASSIGNED: Bilateral subluxation of the PTFJ is a rare clinical entity often associated with specific demographic and physical characteristics, such as young females engaged in high-impact sports. This case underscores the importance of a thorough clinical and imaging evaluation to differentiate it from other causes of lateral knee pain and prominence. Conservative management, including physical therapy and routine follow-ups, has proven effective in managing symptoms and avoiding progression, highlighting the non-operative approach in treating this condition.

BACKGROUND: Non-operative treatment (NOT) of proximal humerus fractures (PHF) has regained significance due to recent evidence. Additionally, positive outcomes of plate osteosynthesis and fracture arthroplasty prompt a reassessment of the role of intramedullary nailing (IMN). While favorable short and medium-term results have been documented following IMN, little is known regarding functional outcomes and quality of life in the long-term.
METHODS: Data from 180 patients with dislocated PHF of Neer types III, IV and V, treated at our level-I trauma center between 2004 and 2014 using IMN or NOT therapy, were scanned. Patients were re-evaluated after a minimum of 5 years to assess functional outcomes (age- and sex-adapted Constant Score, QuickDASH), quality of life (SF12), and complications or reoperations.
RESULTS: Out of the initially identified 180 patients, 51 were unavailable for follow-up (FU) and 71 had deceased during the FU period. Functional outcomes and quality of life was, therefore, assessed in 58 patients (30 IMN, 28 NOT) with an average age at injury of 68 years after a mean FU time of 10.3 ± 3.4 years. Epidemiological patient characteristics did not exhibit significant differences between the two groups (p > .05). The functional outcome assessed by age- and sex-adapted Constant Score (NOT: 74 ± 28; IMN: 68 ± 24; p = .438), QuickDASH (NOT: 25 ± 27; IMN: 31 ± 23; p = .374) or quality of life using the SF12 (p > .05) revealed no significant disparities in long-term outcomes between the treatment groups. 10 of 30 patients in the IMN group underwent surgical revision to address complications, exceeding mere implant removal. Conversely, no patient in the NOT group underwent a revision surgery during the FU period.
CONCLUSIONS: In the long-term, functional and quality of life-related outcomes of IMN did not diverge significantly from those of NOT, while causing a higher incidence of follow-up interventions.

BACKGROUND: Treatment of proximal humerus fractures remains controversial. Understanding the factors that can affect the long-term functional outcomes can aid with management choices. This primary aim of this paper is to evaluate the association of radiographic parameters with functional outcomes.
METHODS: Radiographic parameters [Caput-collum-diaphyseal (CCD) angles, Y-scapular angles, and humeral head height (HHH)] were studied. The patients were split into varus and valgus groups based on the CCD angles and retroverted and anteverted groups based on Y-scapular angles. Functional outcome was measured by Oxford Shoulder Score (OSS), Constant Shoulder Score (CSS), and quick Disabilities of Arm, Shoulder and Hand score at 1 year follow-up. Intra- and interrater reliability were measured with the intraclass correlation coefficients (ICCs). Receiver operator curve (ROC) analysis and logistic regression analysis defined the optimal value for abnormalities on radiographic evaluation as an outcome predictor.
RESULTS: 111 patients were recruited (mean age 69, 78% female). Median final radiographic assessment was at 7 months. Mean initial/final CCD was 119o /111o (varus, n = 36) and 153o/140o (valgus, n = 75). Mean initial/final Y-scapula angle was 27o/27o (retroversion, n = 101) and 70o/40o (anteversion, n = 9). There was a significant relationship between OSS and final Y-scapular angle in the retroverted group (adj coeff 0.034, p = 0.009) with optimum predictive retroversion angulation of 25o predicting poor functional outcome (OSS < 40), area under the ROC curve of 0.614. Higher initial valgus and retroversion significantly predicted more change in the final angle (adj coeff - 0.349, p = 0.002, adj coeff - 0.527, p < 0.001 respectively). Both intra-rater and inter-rater reliability for the radiographic parameters were excellent (ICC > 0.9).
CONCLUSIONS: Radiographic parameters whilst having excellent reliability, have a limited ability to predict short-term functional recovery. The extent of retroversion is the most important predictor for functional recovery with 25o a cut-off guide. Fractures with a higher initial valgus and retroversion tend to displace more.

Hallux rigidus is a degenerative arthritic condition affecting the first metatarsophalangeal joint. Prevalence in patients aged 50 years and above is estimated at 20% to 30%, with a portion being symptomatic. Conservative treatment\'s efficacy is linked to initial pain levels; though shoe modifications and insoles are commonly recommended, their true effectiveness lacks strong evidence. Injection therapy, including corticosteroids and hyaluronic acid, demonstrates varied outcomes, with about 50% of patients undergoing surgery within 1 to 2 years. The condition\'s etiology remains elusive, but recent biomechanical hypotheses hold promise.

OBJECTIVE: Chronic subdural hematoma (CSDH) is a common neurological condition and is typically treated with burr hole craniostomy. Nevertheless, conservative treatment may lead to spontaneous hematoma resolution in some patients. This study aims to describe the characteristics of patients who were treated conservatively without the eventual need for additional treatment.
METHODS: Data were retrospectively collected from patients who were primarily treated conservatively in three hospitals in the Netherlands from 2008 to 2018. The Primary outcome was the nonnecessity of additional treatment within 3 months after the initial CSDH diagnosis. We used univariable and multivariable logistic regression analyses to identify factors associated with not receiving additional treatment.
RESULTS: In this study, 83 patients were included and 61 patients (73%) did not receive additional treatment within 3 months. Upon first presentation, the patients had a Markwalder Grading Scale score (MGS) of 0 (n = 5, 6%), 1 (n = 43, 52%), and 2 (n = 35, 42%). Additional treatment was less often received by patients with smaller hematoma volumes (adjusted odds ratio [aOR] 0.78 per 10 mL; 95% confidence interval [CI] 0.64-0.92). Patients using antithrombotic medication also received less additional treatment, but this association was not significant (aOR 2.02; 95% CI 0.61-6.69).
CONCLUSIONS: Three quarters of the initially conservatively treated CSDH patients do not receive additional management. Typically, these patients have smaller hematoma volumes. Further, prospective research is needed to distinguish which patients require surgical intervention and in whom primary conservative treatment suffices.

UNASSIGNED: Anterior cruciate ligament (ACL) rupture is a prevalent sports injury with rising rates attributed to increased population participation in sports activities. ACL rupture can lead to severe knee complications including cartilage damage, torn meniscus, and osteoarthritis. Current treatment options include conservative measures and surgical interventions. However, debates persist regarding the optimal approach.
UNASSIGNED: This analysis intended to compare the function, knee stability, and incidence rate of secondary surgery between conservative and surgical treatments in ACL rupture patients.
UNASSIGNED: A systematic search was performed via Embase, Ovid Medline, PubMed, Cochrane Library, Web of Science, and Google Scholar for reporting outcomes of conservative and surgical treatments after ACL rupture. The outcomes included patient-reported outcome measures (PROMs), knee stability, the need for secondary meniscal surgery, delayed ACL reconstruction surgery, and revision ACL reconstruction surgery. Outcomes were analyzed using mean differences or odd ratios (OR) with 95 % CIs.
UNASSIGNED: 11 studies were included with 1516 patients. For PROMs, our evidence indicated no differences in KOOS Pain, KOOS Symptoms, KOOS Sport/Rec, KOOS ADL, and KOOS QOL. (all p > 0.05). for knee stability, pivot shift (OR, 0.14; p < 0.001), Lachman test (OR, 0.06; p < 0.001), and tibia translation (p < 0.001) were evaluated, and the available evidence favored surgical treatment over conservative treatment. For the incidence rate of any secondary surgery after the first diagnosis, the surgical group showed a lower rate of meniscal surgery with statistical significance (OR, 0.37; p < 0.001). The average rate of revision ACL reconstruction is 5.80 %, while the rate of delayed ACL reconstruction after conservative treatment is 18.51 %.
UNASSIGNED: Currently, there is insufficient empirical evidence to advocate a systematic surgical reconstruction for any patient who tore his ACL. This review found no differences in function outcomes between conservative and surgical treatments. Regarding knee stability and secondary meniscal surgery, the results prefer the surgical treatments. The occurrence rate of revision and delayed ACL reconstruction are non-negligible factors that must be fully understood by both surgeons and patients before choosing a suitable treatment.

BACKGROUND: Despite fractures of Isolated Weber B being prevalent, there is a lack of clarity regarding the relative effectiveness of surgical versus conservative treatment. This systematic review and meta-analysis aimed to investigate the clinical effects and complications of surgical versus conservative treatment of the Isolated Weber B ankle fractures.
METHODS: This study involved thorough searches across multiple electronic databases, including PubMed, Cochrane, Embase, and Web of Science, to identify all relevant publications on Isolated Weber B ankle fractures repaired through surgical versus conservative treatment. Through a comprehensive meta-analysis, several outcomes were evaluated, including post-operative function, complications and reoperation rate.
RESULTS: Six articles involving 818 patients who met the inclusion criteria. Among these participants, 350 were male and 636 were female. 651 patients received conservative treatment, while 396 underwent surgical intervention. The findings indicate no significant differences in OMAS, FAOQ, PCS, MCS scores, and return to work between surgical and non-surgical treatments for isolated Weber B ankle fractures. However, compared with surgical treatment, non-surgical treatment has a higher AOFAS score(MD = -5.31, 95% CI = [-9.06, -1.55], P = 0.20, I2 = 39%), lower VAS score(MD = 0.72, 95% CI = [0.33, 1.10], P = 0.69, I2 = 0%), lower complication rate (RR = 3.06, 95% CI = [1.58, 6.01], P = 0.05, I2 = 54%), and lower reoperation rate(RR = 8.40, 95% CI = [1.57, 45.06], P = 0.05, I2 = 67%).
CONCLUSIONS:
