Extracorporeal Shockwave Therapy Is Associated With Similar Functional Outcomes for Male and Female Runners With Patellar or Quadriceps Tendinopathy: A Pilot Investigation

PurposeThe purpose of this study is to characterize functional outcomes in runners with patellar tendinopathy (PT) and quadriceps tendinopathy (QT) following extracorporeal shockwave therapy (ESWT) and explore differences in response by tendinopathy (PT or QT) and by sex (female or male). MethodThis is a retrospective cohort study of runners with PT or QT treated with ESWT (radial or combined) at a single sports medicine clinic during a 5-year period. Individuals were included if they had a primary diagnosis of PT or QT, self-identified as a runner, and had complete baseline and final functional outcome questionnaires for ESWT with treatment duration defined by response based on best practices. Functional outcome at baseline and following treatment were assessed using the Victorian Institute of Sport – Patellar Tendon (VISA-P) questionnaires. Treatment success was defined as meeting minimal clinically important difference (MCID) of ≥13 points. ResultsOf the 19 runners included, 26% identified as female and 74% as male; all runners identified as cisgendered. There were 12 runners with PT (17% female, 83% male) and 7 with QT (43% female, 57% male). Median follow-up was 3.0 months (range: 1.0-23.0, IQR: 3.0, 6.0). Of all runners, 67% with PT and 71% with QT achieved MCID with no significant difference between tendinopathy groups (p= 0.90). There was also no difference in the percentage that achieved MCID between sexes, with 80% females and 64% males meeting MCID (p=0.72). ConclusionsSimilar functional outcomes were observed in female and male runners with QT or PT following radial and combined ESWT, with the majority achieving MCID. This study suggests that ESWT, in combination with physical therapy, may be an effective treatment for runners with PT or QT and that ESWT could be considered for PT or QT refractory to physical therapy.

Instability after reverse shoulder arthroplasty: a retrospective review of thirty one cases.

A retrospectively analyze of instability after RSA in terms of aetiology, treatment and final functional outcome. A bicentric retrospective study of 31 patients (mean age 67.6 years; 42-83) treated for RSA instability using RSA Arrow System (FH Orthopedics, Mulhouse, France), mean follow-up 41months (range 12-158). Aetiologies for dislocation were evaluated using a previously described classification system for RSA instability. Actions performed during the Revision Surgeries were analyzed and grouped into five categories. Clinical outcome measures included range of motion, SSV, VAS, Constant-Murley scores, satisfaction level and recurrence of instability. The most frequent aetiology for RSA instability was loss of compression (18), followed by impingement (8) and loss containment (5). Total RSA revision (bipolar procedure) involving both distalization and lateralization occurred in 13 instances. Isolated distalization through the humerus was performed in ten patients and Isolated lateralization through the glenoid in three patients. Three cases of components exchange due to mechanical failure were noted. Bone graft was used in nine instances. Three patients (10%) suffered recurrent instability following Revision Surgery and required an additional stabilizing procedure. At final follow-up all 31 RSA were reported as stable with a mean VAS of 1.1, SSV 54.5%, constant score 48.3, constant ponderate 74.9%. The management of unstable RSA represent a challenge that can be successfully overcome with a revision surgery with compromised functional results. Loss of compression was the most common cause for primary and recurrent RSA instability that were treated principally with bipolar revisions involving component lateralization and distalization.

Open Reduction and Fixation of Late-Presenting Pediatric Supracondylar Humeral Fractures: A Prospective Study.

Supracondylar humeral fracture (SCHF) is a common injury in children, and early treatment provides excellent results and prevents disabilities. Delayed presentation is still prevalent, mainly in developing countries, because many factors hinder the opportunity to receive appropriate treatment. Currently, there are no standard treatment protocols, and there is insufficient published literature on this topic. This study aimed to evaluate the effectiveness and outcomes of open reduction and Kirschner wire fixation using a triceps-sparing posterior approach in neglected cases with complicated fractures. This was a prospective multicenter clinical study conducted between July 2016 and June 2021, which included 28 pediatric patients with neglected SCHF who presented to the hospital for definitive treatment five days or more after initial trauma without previous surgical intervention. All the patients underwent open reduction and K-wire fixation using a posterior triceps-sparing approach. The final functional outcome was assessed using the Mayo Elbow Performance Index (MEPI) and Flynn criteria. All fractures (100%) united within 3-5.5weeks (mean 4 ± 0.7 weeks). Excellent scores observed in 67.9% (n = 19), good in 21.4% (n = 6), fair in 7.1% (n=2), and poor in 3.6% (n = 1) patients according to MEPI. Correspondingly, Flynn's criteria showed 96.4% (n = 27) satisfactory and 3.6% (n = 1) unsatisfactory outcome. Open reduction and fixation using Kirschner wires through the posterior triceps-sparing approach is an effective treatment method for late-presenting SCHF in children with consequent satisfactory results.

Outcomes of surgical revascularization for pediatric moyamoya disease and syndrome

PurposeMoyamoya disease and syndrome represent rare entities characterized by progressive stenosis and/or occlusion of the intracranial blood vessels. We present our series of patients with moyamoya disease and syndrome stratified by underlying disease and analyze differences in presentation and outcome following surgical revascularization.MethodsThis was an Institutional Review Board (IRB) approved, retrospective review of all patients surgically revascularized by the senior author (SNM) while at Children’s National Hospital in Washington, DC. Demographic data, presenting symptoms and severity, surgical details, and functional and radiographic outcomes were obtained and analyzed for differences among the underlying cohorts of moyamoya disease and syndrome as well as by unilateral or bilateral disease and index or non-index surgeries.ResultsTwenty-two patients were identified with the following underlying diseases: six with idiopathic moyamoya disease, six with sickle cell anemia, five with trisomy 21, and five with neurofibromatosis type 1. Thirty hemispheres were revascularized with a significantly reduced rate of stroke from 3.19 strokes/year (SD = 3.10) to 0.13 strokes/year (SD = 0.25), p = 0.03. When analyzed by underlying cause of moyamoya syndrome, patients with neurofibromatosis type 1 were found to be significantly less likely than the other subtypes of moyamoya syndrome to have had either a clinical stroke (0.0% neurofibromatosis type 1 vs. 100.0% sickle cell, 60.0% trisomy 21, or 83.3% moyamoya disease, p < 0.01) or radiographic stroke (0.0% neurofibromatosis type 1 vs. 100.0% sickle cell, 60.0% trisomy 21, or 83.3% moyamoya disease, p < 0.01) at time of presentation. Patients with moyamoya syndrome associated with sickle cell disease were more likely to present with clinical and radiographic strokes. Additionally, patients with bilateral disease demonstrated no difference in final functional outcome compared to patients with unilateral disease (mRS 0.73 (SD = 1.33) vs. 1.29 (SD = 1.60), p = 0.63).ConclusionIndirect surgical revascularization decreases stroke risk for pediatric patients with different forms of moyamoya disease and moyamoya syndrome. Additionally, these data suggest that sickle cell anemia-associated moyamoya syndrome may represent a more aggressive variant, while neurofibromatosis type 1 may represent a more benign variant.

Functional Outcomes and Their Influencing Factors for the Surgical Management of T-type Acetabulum Fractures: A Prospective Single-Centre Study of 73 Patients.

Introduction T-type fractures of the acetabulum are uncommon injuries, typically resulting in poorer long-term outcomes compared to other patterns of acetabular fractures. Our main purpose is to analyse the epidemiology, functional outcomes, and factors affecting the functional outcomes of patients with T-type acetabular fractures. Methods This prospective, single-centre study included 73 patients with T-type and T with posterior wall acetabular fractures. They underwent treatment with open reduction internal fixation using plating through the modified Stoppa, Kocher-Langenbeck (KL), or dual approach. The post-operative reduction was assessed according to Matta's criteria, and functional outcomes were evaluated using the modified Harris hip score. Results Between September 2017 and January 2023, 53 patients underwent surgery for T-type fractures (72.6%),and 20 patients were treated for T with posterior wall acetabular fractures (27.4%). The minimum follow-up period was one year, with a mean follow-up of 3.5 years. Anatomical reduction emerged as the major contributing factor towards good functional outcomes compared to satisfactory reduction according to Matta's criteria (P value: 0.006). Overall, 65 patients (89%) achieved excellent to good modified Harris hip scores, while eight patients (11%) obtained fair to poor scores. Patients with T-type fractures demonstrated better functional outcomes compared to T with posterior wall fractures (P value: 0.031). Conclusion Anatomical reduction, as assessed by Matta's reduction criteria, serves as a predictor of favourable functional outcomes. T with posterior wall fractures exhibit poor outcomes in comparison to T-type fractures. The surgical approach employed does not influence the reduction or the final functional outcome of the patient.

Comparison of elastic stable intramedullary nailing versus Kirschner wires in treatment of pediatric radial neck fractures.

The aim of the study was to compare the different internal fixations between elastic stable intramedullary nailing and Kirschner wires in treatment of angulated radial neck fractures. We retrospectively reviewed the patients with radial neck fracture without associated injuries who underwent surgery approach in our department during April 2011-March 2020. There were 62 patients meeting all the criteria with complete clinical data, with median age of 7.5 (IQR 5.8-9.5) years, 34 males and 28 females. The preoperative fracture pattern was assessed according to the Judet classification system. Depending on the materials implanted and fixation strategy, the patients could be divided into a Kirschner wire group and an elastic stable intramedullary nailing group. Final functional outcomes of patients were assessed by the Mayo Elbow Performance Score and Tibone-Stoltz functional evaluation classification. The Kirschner wire group included 37 patients, with 4.8 years median follow-up. The elastic stable intramedullary nailing group included 25 patients with 5.9 years median follow-up. There were no significant differences in gender, age, Judet classification, average operative time, Mayo Elbow Performance Score, Tibone-Stoltz classification, or length of hospital stay between groups. However, the time to union in the Kirschner wire group was significantly shorter than that in the elastic stable intramedullary nailing group (p < 0.05). Both groups achieved satisfactory functional and cosmetic results. In the management of pediatric radial neck fractures, both elastic stable intramedullary nailing and Kirschner wire internal fixation have shown equivalent therapeutic results, leading to satisfactory functional outcomes. The selection of the internal fixation approach can be influenced by the patient's fracture characteristics and the surgeon's preferences. Level III; Retrospective Comparison; Treatment Study.

Effect of Botulinum Toxin Type-A on Improvement of Muscle Function of Lower Limb in Children with Spastic Cerebral Palsy

Background: Spasticity significantly contributes to the functional and postural impairments in children with cerebral palsy (CP), leading to limitations in daily independence, participation, and quality of life. Botulinum Toxin-A (BTX-A) is recognized as an effective treatment for improving outcomes related to spasticity in individuals with CP. Objectives: This study aimed to evaluate the impact of BTX-A treatment on lower limb muscle function in children with spastic CP who were unable to complete physiotherapy sessions due to muscle spasms. Methods: This cross-sectional study reviewed the medical records of 24 children with CP (14 boys, 10 girls; average age: 4.50 ± 2.70 years) who had received BTX-A injections. We recorded demographic characteristics, types of muscle dysfunction, and the number of muscles involved. BTX-A injections were administered at a dosage of 5 units/kg across multiple sites. The severity of spasticity (measured using the Ashworth scale) and motor performance (assessed by the ability to walk and stand) were evaluated 30 days after the BTX-A injection. Satisfaction levels of surgeons, physiotherapists, and parents, along with final functional outcomes, were also gathered. Data analysis was performed using SPSS. Results: The most common movement disorders observed were equinus, knee flexion, and adduction. The median score on the Ashworth scale significantly decreased (P &lt; 0.001) following BTX-A injection. There was a notable improvement in walking and standing performance (P &lt; 0.05), particularly among boys aged 3 years or younger (P &lt; 0.05). Most cases showed satisfactory outcomes 30 days after BTX-A injection. Significant enhancements in the functional outcomes of children with CP were noted after a 30-day follow-up, with no significant differences related to gender, age, or the muscles involved (P &gt; 0.05). Conclusions: The findings suggest a substantial reduction in spasticity and enhancement of functional outcomes in children with cerebral palsy after BTX-A injections. This improvement was especially evident in boys and younger children with fewer muscles involved, accompanied by notably satisfactory outcomes.

Can Distalisation and Lateralisation Shoulder Angles in Reverse Arthroplasty Interfere with the Functional Results in Patients with Rotator Cuff Arthropathy?

Objective: To evaluate the influence of radiographic values on clinical and functional results in patients treated with reverse arthroplasty for rotator cuff arthropathy (RCA) using a lateralized design. Methods: A retrospective analysis was performed. Patient demographics were recorded, as well as preoperative and postoperative range of motion. Function was calculated using the Constant-Murley score both before and after the procedure. Pre and postoperative anteroposterior and axial radiographs of the affected shoulder were analysed. In the preoperative images, the following was calculated: acromiohumeral distance (AHD) and lateral humeral offset (LHO). Postoperative measurements included: AHD, LHO, distalization shoulder angle (DSA) and lateralisation shoulder angle (LSA). Linear regression and quadratic regression analysis was performed to determine their degree of association with final functional outcomes. By applying a quadratic regression analysis and ROC curves, the cut-off values were determined with respect to the above-mentioned angles and the positive predictive value was calculated. Results: The greater anterior elevation (AE) ranges were found with DSA between 40-45° and LSA among 80°- 90°, while better ABD was observed with LSA of 90-100°. Preoperative AHD was correlated to RE (r s :0.47; p:0.049). Postoperative AHD was found to be in a directly proportional relationship with AE (r s :0.49; p:0.03). Postoperative ABD showed an inverse linear regression with preoperative AHD (r s : -0.44, p:0.047). LSA and DSA were inversely related. Conclusion: We found that a DSA between 40-45° and a LSA of 80-100° could lead to better range of motion regarding AE and ABD in patients with rotator cuff arthropathy treated with RSA.

Automated detection of early signs of irreversible ischemic change on CTA source images in patients with large vessel occlusion.

To create and validate an automated pipeline for detection of early signs of irreversible ischemic change from admission CTA in patients with large vessel occlusion (LVO) stroke. We retrospectively included 368 patients for training and 143 for external validation. All patients had anterior circulation LVO stroke, endovascular therapy with successful reperfusion, and follow-up diffusion-weighted imaging (DWI). We devised a pipeline to automatically segment Alberta Stroke Program Early CT Score (ASPECTS) regions and extracted their relative Hounsfield unit (rHU) values. We determined the optimal rHU cut points for prediction of final infarction in each ASPECT region, performed 10-fold cross-validation in the training set, and measured the performance via external validation in patients from another institute. We compared the model with an expert neuroradiologist for prediction of final infarct volume and poor functional outcome. We achieved a mean area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, and specificity of 0.69±0.13, 0.69±0.09, 0.61±0.23, and 0.72±0.11 across all regions and folds in cross-validation. In the external validation cohort, we achieved a median [interquartile] AUC, accuracy, sensitivity, and specificity of 0.71 [0.68-0.72], 0.70 [0.68-0.73], 0.55 [0.50-0.63], and 0.74 [0.73-0.77], respectively. The rHU-based ASPECTS showed significant correlation with DWI-based ASPECTS (rS = 0.39, p<0.001) and final infarct volume (rS = -0.36, p<0.001). The AUC for predicting poor functional outcome was 0.66 (95%CI: 0.57-0.75). The predictive capabilities of rHU-based ASPECTS were not significantly different from the neuroradiologist's visual ASPECTS for either final infarct volume or functional outcome. Our study demonstrates the feasibility of an automated pipeline and predictive model based on relative HU attenuation of ASPECTS regions on baseline CTA and its non-inferior performance in predicting final infarction on post-stroke DWI compared to an expert human reader.

Transscleral fixation of intraocular lens in the treatment of lens subluxation in children

This study evaluated the effectiveness and safety of IOL implantation with transscleral fixation using the knotless Z-suture technique in pediatric patients with congenital lens subluxation. The study included 24 children (36 eyes) with grade III congenital subluxation of the lens who underwent phacoaspiration of the subluxated lens with IOL implantation with transscleral fixation using the knotless Z-suture performed in the Kazakh Research Institute of Eye Diseases in Almaty in the period from 2017 to 2021. The average observation period was 31.7±11.3 months (2.0 to 4.5 years). The stability of the IOL position, the state of the intrascleral sutures, visual acuity after surgery, the presence and severity of complications in the long-term period were evaluated. All patients (100%) had a significant improvement in visual acuity after surgery. No intraoperative complications were registered in any of the cases. Postoperative complications were noted in 8.3% of cases (n=3). The final functional outcome of surgical treatment depended on the presence of concomitant pathology, the main cause of low vision was the development of refractive amblyopia due to refractive errors. The presented technique of transscleral fixation of IOL has proven to be reliable, which is especially important for pediatric patients considering their high physical activity and expected lifespan.

Distal Femur Megaprostheses in Orthopedic Oncology: Evaluation of a Standardized Post-Operative Rehabilitation Protocol.

Megaprostheses are the most used reconstructive approach for patients who have undergone massive resection of their distal femurs due to bone tumors. Although the literature about their outcomes has flourished in recent decades, to date, a consensus on rehabilitative treatment is yet to be established. In this study, we report on our experience with our latest standardized rehabilitation program, evaluating our results in a mid-to-long-term scenario. We evaluated the functional results of all our oncologic patients treated between 2016 and 2022 who could follow our standardized post-operative rehabilitative approach, consisting of progressive knee mobilization and early weight-bearing. Sixteen cases were included in our study. The average duration of the patients' hospitalization was 12.2 days. A standing position was reached on average 4.1 days after surgery, while assisted walking was started 4.5 days after surgery. After a mean post-operative follow-up of 46.7 months, our patients' mean MSTS score was 23.2 (10-30). Our data suggest that the sooner patients could achieve a standing position (R = -0.609; p = 0.012) and start walking (R = -0.623; p = 0.010), the better their final functional outcomes regarding their MSTS scores. Rehabilitation should be considered a pivotal factor in decreeing the success of distal femur megaprosthetic implants in long-surviving oncologic patients. Correct rehabilitation, focused on early mobilization and progressive weight-bearing, is crucial to maximizing the post-operative functional outcomes of these patients.

Cytokine Profiling in Human iPSC-Derived Dopaminergic Neuronal and Microglial Cultures.

Aside from the degeneration of dopaminergic neurons, inflammation is a key component in the movement disorder Parkinson's disease (PD). Microglia activation as well as elevated cytokine levels were observed in the brains of PD patients, but the specific role of microglia in the disease process is unknown. Here, we generate human cellular models by differentiating iPSCs into dopaminergic neurons and microglia. We combine these cells in co-culture to perform cytokine profiling, representing the final functional outcome of various signaling pathways. For this, we used unstimulated conditions and treatment with inflammatory stressors. Importantly, only co-cultures but not the monocultures responded to IL-1β treatment suggesting co-culture-related crosstalk. Moreover, we identified the main types of released cytokines and chemokines in this model system and found a preference for the activation of the chemotaxis pathway in response to all treatments, which informs future studies on the cell-type-specific reaction to inflammatory stimulation. Finally, we detected protein level changes in PD risk factor GPNMB upon stress in microglia, further confirming the link between PD-associated genes and inflammation in human-derived cellular models.

Do Syndesmotic Injury Patterns Influence Functional and Radiological Outcomes in Complex Ankle Fractures? A Retrospective Cohort Study

Category: Ankle; Trauma Introduction/Purpose: Syndesmosis injury can be of a varying magnitude; little information exists about the influence of degree of initial syndesmotic injury/instability on functional outcomes in ankle fractures, nor is there any correlation of this with follow up radiological parameters. Aims and Objectives: To identify and define morphological patterns of syndesmotic injury in ankle fractures according to a zone based evaluation, and correlate initial degree of instability with mid-term functional and radiological outcomes using validated scores Design: Retrospective cohort study, to review a prospective question. Methods: 40 complex ankle fractures out of 120 ankle fractures in our ankle registry met the inclusion criteria ie significant documented syndesmosis involvement needing stabilization, with all initial clinical and radiological records available. The patients were followed up between January 2020 to July 2021. Injury characteristics, fracture morphology of posterior malleolus, medial malleolus and fibula were noted and classified by validated classification systems based on x-rays and CT scan. The syndesmosis was analyzed on axial CT scan; it was divided into 3 zones, A,B,C from anterior to posterior, and degree of displacement and morphology was noted. Immediate post-operative radiographs were evaluated for fracture and syndesmosis reduction. The patients were evaluated at final follow up with both ankle specific scores (Olerud Molander score, Ankle-Hindfoot scale, Manchester-Oxford Foot questionnaire) and quality of life score (SF-12). Ankle Osteoarthritis grade was used to evaluate radiological outcomes. Results: Mean follow-up was 19 months. 22(55%) patients had syndesmotic widening on plain radiographs; however in pre- operative CT scan evaluation 40(100%) patients had syndesmotic injury based on the Zone evaluation of the syndesmosis. 22 patients had Zone A injury (widening, AITFL, Chaput, Wagstaff). 22 patients had widening of Zone B. Zone C was involved in 30 patients (PM fracture,PITFL involvement). At final follow up; the mean OMAS was 83.38±16.35, mean Ankle-Hindfoot scale= 88±9.98, mean Mox-FQ score=27.15±13.35 &amp; mean SF-12 were (MCS=56.59±8.24, PCS=51.18±8.48). There was no significant difference in outcome scores based on fracture types, Posterior malleolus morphology, or based on zones of syndesmosis injury. Syndesmosis malreduction contributed to significantly poorer outcomes (SF-12, OMAS, MoxFQ) Conclusion: Despite a zonal classification of syndesmotic injury on CT and more clarity of injury patterns, we could not corelate the site and extent of syndesmotic injury with final functional and radiological outcomes. The one factor that has significant influence is initial accurate reduction of both the malleolar fractures and syndesmosis injury. In this the CT based axial classification may play a role.

To Bury or Not to Bury the K-wires After Fixation of Both Bone Forearm Fractures in Patients Younger Than 11 Years Old: A Randomized Controlled Trial.

The primary objective was to compare the re-fracture incidence of both radius and ulna fracture in 2 groups treated using intramedullary Kirschner wires (K-wires) where the wires were exposed in group I and buried in group II. The secondary objective was to compare the final functional outcomes and complications incidence. Between March 2019 and February 2021, 60 pediatric patients with unstable radius and ulna fractures amenable to surgical intervention using intramedullary K-wires were randomized into group I (K-wires were exposed above the skin by 2cm) or group II (K-wires were buried under the skin). In group I, K-wires were removed in the outpatient clinic, while in group II, they were removed under general anesthesia as a day-case procedure. Functional outcome per Price criteria was reported at 1-year follow-up. Included patients had a mean age of 7.6 years (range: 5 to 10y). The mean operative time was significantly higher in group II (32.33±7.51 vs. 36.77±8.70min, P =0.03), with no difference regarding intraoperative x-ray exposure (43.12±15.52 vs. 41.6±11.96s, P =0.67). Fracture union was achieved after a mean of 44±2.6 days in group I and 43±1.87 days in group II, with no difference between both groups ( P =0.34). One patient had re-fracture in group I and no patients in group II; however, the difference was insignificant ( P =0.12). Infection occurred in 2 patients in each group. All patients reported excellent scores per Price criteria and achieved full wrist and elbow range of motion compared with the contralateral noninjured side. Exposed implants are a safe option when dealing with forearm fractures in patients younger than 11 years old, with the added advantage of fewer hospital admissions. Furthermore, it had a similar complication rate and functional outcomes compared with buried implants. ClinicalTrials.gov, NCT03906929. Level II.

Functional and structural outcomes and complications after pars plana vitrectomy for severe features of proliferative diabetic retinopathy in type 1 and type 2 diabetes mellitus.

To evaluate the functional and structural outcomes as well as postoperative complications after pars plana vitrectomy (PPV) for severe features of proliferative diabetic retinopathy (PDR) in type 1 and type 2 diabetes mellitus (DM) patients. Twenty two eyes of type 1 diabetics (DM1 group) and 27 eyes of type 2 diabetics (DM2 group) were included. Best corrected visual acuity (BCVA), intraocular pressure (IOP), postoperative structural changes in optical coherence tomography (OCT) and postoperative complications such as recurrent vitreous haemorrhage, diabetic macular oedema, secondary glaucoma and persistent tractional retinal detachment (TRD) were assessed and compared between the two groups. Complete reattachment of retina was achieved in 88.9% from the DM1 group and in 95.5% from the DM2 group and remained attached in follow-up. BCVA in DM2 group was significantly lower preoperatively (p = 0.04). Mean postoperative BCVA significantly improved in both studied groups, but it was more evident in eyes of type 2 diabetics compared to type 1 diabetics. In eyes in the DM1 group there was perceptible stabilisation of BCVA. Poor visual acuity or lack of improvement in BCVA in the DM1 group was related to preoperative subretinal haemorrhage in macular region, and TRD involving macula, whereas in the DM2 group-to preoperative subretinal haemorrhage and neovascular glaucoma. The postoperative structural changes (disruption of EZ and ELM) were observed more often in DM2 group, but had the greatest impact on BCVA in eyes of type 1 DM. Complications after PPV for PDR were rare and hadn't a significant influence on the final functional outcomes in both groups. Functional improvement after PPV for severe features of proliferative diabetic retinopathy were more noticeable in patients with type 2 DM. Postoperative structural changes had more negative impact on BCVA in type 1 diabetics.

The modified capsular arthroplasty foryoung patients with developmental dislocation ofthe hip.

The present study aimed to investigate the clinical results of the modified Codivilla-Hey Groves-Colonna capsular arthroplasty in the treatment of young patients with developmental dislocation of the hip. We retrospectively evaluated 90 patients (92 hips) who underwent the modified capsular arthroplasty from June 2012 to June 2021. Hips were evaluated using the modified hip Harris score (mHHS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and the 12-item International Hip Outcome Tool (iHOT-12). The Tönnis osteoarthritis grade and the Severin classification system were used to assess the radiographic outcomes. The average age was 15.7 years (range: 8-26 years). The mean pre-operative mHHS, the WOMAC score and the iHOT-12 score were 83.03, 14.05 and 52.79, respectively. The patients were followed for a mean of 41.1 months (range: 12.1-120.9 months). The patients had a mean mHHS of 83.61 (range: 31.2-97), a WOMAC score of 16.41 (range: 0-51) and an iHOT-12 score of 64.81 (range: 12.9-98.2) at the final follow-up. Capsular thickness had a positive predication on the final functional outcomes. The excellent/good rate of radiological reduction was 79.3%. More than 60% of patients had no/slight osteoarthritis. A total of 54 hips (58.7%) had superior radiographic outcomes. The risk factors for inferior radiographic outcomes were capsular quality (odds ratio [OR]: 0.358, 95% confidence interval [CI]: 0.113-0.931) and capsular thickness (OR: 0.265, 95% CI: 0.134-0.525). Joint stiffness was the most common complication (14.1%). We confirmed the efficacy of this procedure in the treatment of developmental hip dislocation. Patients with poor capsular quality are not suitable for this procedure. With suitable selection according to indications, this procedure can restore the hip rotation center with a low incidence of femoral head necrosis or severe osteoarthritis.

Preoperative incongruent subtalar joint predicts less favorable clinical outcome in total ankle arthroplasty

BackgroundThis study aimed to determine the clinical effect of incongruent subtalar joint space on total ankle arthroplasty (TAA). MethodsThirty-four consecutive patients who underwent TAA were grouped according to the status of subtalar joint incongruency. A comparison of clinical and radiographic parameters between groups as well as multiple regression analysis was performed to identify contributing factors to the final functional outcome. ResultsThe final American Orthopaedic Foot and Ankle Society (AOFAS) score was significantly higher in the congruent group compared to that of the incongruent group (p = 0.007). There were no significant differences between the two groups in measured radiographic angles. In multiple regression analysis, the female sex (p = 0.006) and incongruency of the subtalar joint (p = 0.013) were found to be significant contributing factors to the final AOFAS score. ConclusionsA thorough preoperative investigation should be taken into the state of the subtalar joint for TAA.

Radiological and Functional Outcome of Internal Fixation of Monteggia Fracture Dislocation by DCP in Adult Patients

Background: Surgical reduction and internal fixation are the mainstays for the treatment of the Monteggia fracture-dislocation in adult and there are various surgical modalities for internal fixation. Various types of implants used in fixation of Monteggia fracture dislocation in adult and the outcome also differ. Small DCP is one of the important implants. The fracture of the proximal third of the ulna with dislocation of the head of the radius was commonly known as Monteggia fracture dislocation. Objective: To assess the radiological and functional outcome of internal fixation of monteggia fracture dislocation by (DCP) in adult patients. Methods: This prospective observational study had been conducted in Monno Medical College and Hospital, Manikganj, to evaluate the results of open reduction and internal fixation of the ulna with small DCP and anatomical reduction of radial head in early cases of Monteggia fracture dislocation in adult from January 2022 to December 2022. Total 40 patients with radiologically proven closed Monteggia fracture-dislocation that were enrolled in this study by purposive sampling method. Radiological and functional outcome were assessed and followed up for 24 weeks. Results: Results were evaluated by Quick DASH score, VAS scale, ROM of flexion-extension and supination-pronation. Final functional outcome was done with Anderson criteria. Results: Total 40 patients were included. Among 15 (37.5%) patients were from 20-29 years age group, 8 (20.0%) were from 30-39 years age group, 11 (27.5%) were from 40-49 years age group and 6 (15.0%) were from 50-55 years age group. The mean age of the patients was 35.96±11.48 years where minimum age was 20 years and maximum age was 55 years. 32 (80.0%) patients were male and 8 (20.0%) patients were female. Out of the 40 patients, 35 (87.5%) presented with Bado type I fracture and 5 (12.5%) presented with Bado type II fracture. The mean time interval between injury and surgery was 10.13±3.86 days. Post-operative complications (tourniquet palsy and wound infection) developed in 5 (12.5%) patients. According to Anderson criteria nine (22.5%) patients had excellent, 25 (62.5%) patients had good, 3 (7.5%) had fair and 7 (7.5%) patients had poor outcome. Final outcome was satisfactory (excellent and good) in 35 (87.5%) patients and unsatisfactory (fair and poor) in 5 (12.5%) patients. Patients who had Bado type II fracture had less satisfactory outcome (p=0.004). Again, patients who had more time interval between injury and surgery also had less satisfactory outcome (p=0.012). Conclusion: Monteggia fractures are uncommon injuries. The commonest type of monteggia fracture dislocation in adults according to Bado’s classification is type-1. Operative treatment of Monteggia fracture-dislocation by the selected implant, leads to excellent to good radiological and functional result with uncomplicated recovery in majority of the cases.

Aesthetic Considerations in Extremity Salvage and Reconstruction.

After studying this article, the participant should be able to: 1. Have an in-depth understanding of the functional and aesthetic requirements of lower extremity reconstruction. 2. Describe the considerations for achieving an optimal aesthetic outcome in the primary reconstruction settings. 3. Describe modalities of secondary flap revision for achieving an optimal aesthetic outcome. Significant advancements have been made in the management of lower extremity reconstruction since Dr. Taylor's seminal case in 1973. Improvements in our understanding of vascular anatomy and evolution of microsurgical techniques have allowed for an ever-increasing array of free tissue transfer options for lower extremity reconstruction. The resulting expertise has engendered a paradigm shift toward the reconstructive elevator approach, with increased emphasis on cosmetic results. In the primary setting, aesthetic considerations play an important role in precoverage wound preparation, flap selection, and harvest technique, with the goal of achieving excellent like-with-like reconstruction at the time of initial surgery. Flap selection should be made to best match the three-dimensional architecture of the wound, and take into account the defect thickness, flap thickness, flap composition, and pedicle length. Primary flap thinning and harvest in the superficial fascial plane has been shown to be an effective modality to address excess adiposity and improve contour. Despite these efforts, secondary procedures are often required to optimize the limb's final appearance and functional outcomes, particularly in the foot and ankle region. These include debulking, liposuction, and staged excisions. As the field of limb salvage keeps evolving, aesthetics will continue to play an important role in extremity reconstruction planning and execution.

Are all primary retinal detachments the same? Anatomic and functional differences between phakic and pseudophakic patients

BackgroundGiven differences in the pathogenic mechanisms underlying primary retinal detachment (RD) as a function of the status of the lens, the objective was to explore differences between pseudophakic and phakic patients with primary RD.MethodsA retrospective study including 821 patients who underwent surgery for RD [491 cases of phakic and 330 of pseudophakic RD (pRD and psRD, respectively)] in our hospital between 2012 and 2020.ResultsThe mean age was 58.24 ± 12.76 years in the pRD group and 66.87 ± 11.18 years in the psRD group (p = 0.001). There were more men in both groups (70% and 64.23% of pseudophakic and phakic patients, respectively; p = 0.07). The most common location for the RD was superior in both groups (43.94% and 51.93% of pseudophakic and phakic patients, respectively), rates of inferior and total RD were somewhat higher in the psRD group (31.82% and 13.33% in pseudophakic vs 25.25% and 11.0% in phakic patients, p = 0.001). In pseudophakic and phakic patients respectively, macular involvement in 69.09% and 62.73% of cases (p = 0.067). Proliferative vitreoretinopathy was significantly more common in the psRD group (7.88% vs 3.6% in phakic patients, p = 0.01).The rate of final anatomic reattachment differed markedly between groups, with a higher rate in phakic (94.03%) than pseudophakic (87.27%) patients (p = 0.001).ConclusionsThe specific pathogenic mechanism involved in psRD seems to be responsible for worse evolution characteristics which are associated with poorer final anatomic and functional outcomes in pseudophakic patients.
