Anatomic vs. reverse shoulder arthroplasty for glenohumeral osteoarthritis with intact rotator cuff: a retrospective comparison of patient-reported outcomes using the systems outcomes database with up to 5-year follow-up

BackgroundThe growing enthusiasm for the use of reverse shoulder arthroplasty (RSA) in the treatment of primary glenohumeral osteoarthritis (GHOA) with an intact rotator cuff is based on data derived from single-center studies with limited generalizability and follow-up. This study compared patient-reported outcomes (PROs) between RSA and total shoulder arthroplasty (TSA) for the treatment of primary GHOA with up to 5-year follow-up and examined temporal trends in the treatment of GHOA between 2012 and 2021.MethodsA retrospective review was performed on patients with primary GHOA undergoing primary arthroplasty surgery from the Surgical Outcomes System global registry between 2012 and 2021. PROs including the American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, and visual analog scale (VAS) for pain were compared between RSA and TSA at 1, 2, and 5 years postoperatively.ResultsA total of 4451 patients were included, with 2693 (60.5%) undergoing TSA and 1758 (39.5%) undergoing RSA. Both RSA and TSA provided clinically excellent outcomes at 1 year postoperatively (ASES: 80.8 ± 17.9 vs. 85.9 ± 15.2, respectively; SANE: 74.8 ± 24.7 vs. 79.5 ± 22.9; VAS pain: 1.3 ± 2.0 vs. 1.1 ± 1.7; all P < .05) that were maintained at 2 years (ASES: 81.3 ± 19.3 vs. 87.3 ± 14.9; SANE: 74.8 ± 26.2 vs. 79.7 ± 24.7; VAS pain: 1.3 ± 2.1 vs. 1.0 ± 1.6; all P < .05) and 5 years (ASES: 81.7 ± 16.5 vs. 86.9 ± 15.3; SANE: 71.6 ± 28.5 vs. 78.2 ± 25.9; VAS pain: 1.0 ± 1.7 vs. 1.0 ± 1.7; all P < .05), with statistical significance favoring TSA. After controlling for age and sex, there was an adjusted difference of 4.5 units in the ASES score favoring TSA (P = .005) at 5 years postoperatively but no differences in adjusted SANE (P = .745) and VAS pain (P = .332) scores. The use of RSA for GHOA grew considerably over time, from representing only 17% of all replacements performed for GHOA in 2012 to nearly half (47%) in 2021 (P < .001).ConclusionRSA as a treatment for GHOA with an intact rotator cuff seems to yield PROs that are largely clinically equivalent to TSA extending to 5 years postoperatively. The observed statistical significance favoring TSA appears to be of marginal clinical benefit based on established minimal clinically important differences and may be a result of the large sample size. Further research using more granular clinical data and examining differences in range of motion and complications is warranted as it may change the value analysis.     

Complications in patients of acetabular fractures and the factors affecting the quality of reduction in surgically treated cases

IntroductionAcetabulum fractures, though relatively uncommon, are associated with significant morbidity and mortality. These involve high energy trauma and due to their complex nature, the management requires understanding the relevant surgical anatomy, defining the injury via appropriate radiographic assessment and determining a suitable treatment plan. Literature is scarce for the demographic data, fracture patterns, associated injuries, management and early complications in the Indian scenario. These factors play a pivotal role in the ultimate recovery of the patients. Therefore this study was conceptualised to assess the epidemiology and evaluate the complications of these fractures. Furthermore the effects of various factors determining the quality of reduction in surgically treated patients were also assessed.MethodologyThis was a prospective observational study in which patients presenting to the advance trauma centre of our institute with acetabulum fractures were included. Demographical data of the patients, mechanisms of injuries, fractures morphologies, complications and radiological outcomes were recorded prospectively.Results116 patients with acetabular fractures were included in the study. 81% of these were males, with average age of 39.95 ± 15.87 years; with road traffic accidents being the predominant mode of injuries. Mortality was reported in 5 patients; 4 patients had deep venous thrombosis and sciatic nerve injuries were seen in 12 patients of which 4 were iatrogenic. 8 patients had some form of infection, out of which 4 required multiple debridements. 4 cases developed heterotrophic ossification while 2 cases had loss of reduction. The timing of surgery and other associated fractures had significant effect on the quality of reduction (p < 0.05); while age, gender, mode of injury or individual fracture patterns had no such effect.ConclusionsProper radiological assessment and evaluation of fracture configuration is important for management of acetabulum fractures. When indicated, this should be followed by early open reduction and internal fixation to achieve anatomical reduction, with management of associated injuries for better outcomes.     

A comprehensive 3D CT based classification of intertrochanteric fracture

IntroductionDespite advancements in surgical techniques complications like implant failure is very common after the fixation of intertrochanteric fractures. Classifying these complex fractures based on plain radiographs underestimates the complexity of these fractures which in turn leads to complications. We propose a comprehensive classification of the intertrochanteric fractures based on 3D Non Contrast Computed Tomography (3D NCCT) scan.Material and methodsA total of 102 patients (51 males and 51 females) with intertrochanteric fractures were included in this study conducted over a time period of 22 months in a Tertiary care center in North India. NCCT proximal femur of the intertrochanteric fracture patients was done to formulate a new CT classification system and classify all fractures. Intra and inter-observer reliability was tested using kappa variance.ResultsNew classification system was proposed which included 3 main and a total of 6 groups. All the fractures were classifiable into the new system. Kappa variance of the study showed a good intra and interobserver reliability (0.95 and 0.90) proving clinical agreement of the classification.ConclusionThis new 3D-CT based classification has the advantages of being easy, comprehensible with high intra and inter-observer reliability. This 3DCT based classification can prove to be useful to detect occult intertrochanteric fractures undetectable in plain radiographs as well as choosing the optimum treatment plan.

目的探讨关节镜辅助下轴向螺钉内固定术治疗Sanders-2型跟骨骨折的临床疗效。方法将50例Sanders-2型跟骨骨折患者按照随机数字表法分为研究组与对照组,各25例。研究组给予关节镜辅助下轴向螺钉内固定术治疗,对照组给予传统切开复位内固定术治疗。术后观察3个月。比较两组手术时间、住院时间、骨折愈合时间、术前与术后3个月末两组Bohler角、Gissane角度数及跟骨高度、宽度,以及两组Maryland足功能评分、手术疗效。结果研究组手术时间、住院时间及骨折愈合时间均显著短于对照组(P<0.05或0.01)。术后3个月末两组Bohler角及Gissane角度数均较术前显著增大(P<0.01),研究组较对照组增大更显著(P<0.05或0.01)。术后3个月末研究组跟骨高度显著>术前(P<0.01),两组跟骨宽度均显著>术前(P<0.01),两组间比较差异无统计学意义(P>0.05)。术后3个月末两组Maryland足功能评分均较术前显著升高(P<0.01),研究组较对照组升高更显著(P<0.01)。研究组手术治疗总有效率显著高于对照组(P<0.05),并发症发生率显著低于对照组(P<0.05)。结论关节镜辅助下轴向螺钉内固定术治疗Sanders-2型跟骨骨折效果显著,能有效促进患者足踝功能恢复,安全性较高,值得临床推广应用。     

International Hand Function Study Following Distal Radial Access: The RATATOUILLE Study

BackgroundDistal radial access (DRA) has been proposed to improve procedure ergonomics and favor radial artery patency. Although promising data, nothing is known on evolving hand function after DRA.ObjectivesThis study sought to comprehensively evaluate hand function in patients undergoing DRA.MethodsReal-world patients undergoing DRA undertook a thorough multimodality assessment of hand function implementing multidomain questionnaires (Disabilities of the Arm, Shoulder and Hand and Levine-Katz), and motor (pinch grip test) and sensory (Semmes-Weinstein monofilaments test) examinations of both hands. All assessments were performed at preprocedural baseline and planned at 1-, 6-, and 12-month follow-up (FU). Adverse clinical and procedural events were documented too.ResultsData of 313 patients (220 men, age 66 ± 10 years) from 9 international centers were analyzed. The Disabilities of the Arm, Shoulder and Hand and the Levine-Katz scores slightly improved from baseline to FU (P = 0.008 and P = 0.029, respectively). Pinch strength mildly improved from baseline to FU (P < 0.001 for both the left and right hands). Similarly, touch pressure threshold appeared to faintly improve in both the left and right hands (P < 0.012 for all the sites). For both motor and sensory function tests, comparable findings were found for the DRA hand and the contralateral one, with no significant differences between them. Repeated assessment of all tests over all FU time points similarly showed lack of worsening hand function. Access-related adverse events included 19 harmless bleedings and 3 forearm radial artery and 3 distal radial artery occlusions. None affected hand function at FU.ConclusionsIn a systematic multidimensional assessment, DRA was not associated with hand function impairment. Moreover, DRA emerges as a safe alternative vascular access.
