Outcomes and Return to Sport and Work After Open Bankart Repair for Recurrent Shoulder Instability: A Systematic Review

Background: Open Bankart repair provides surgeons and patients with an alternative solution for managing recurrent instability in young athletes with or without minimal bone loss. Despite many studies that have reported low recurrence rates and good functional outcomes after open Bankart repair, we have limited knowledge about the return to sport and work for high-demand populations. Purpose: To assess the return to sport and work for high-demand populations after open Bankart repair for recurrent anterior shoulder instability, outcomes of open Bankart repair with regard to recurrence, and development of osteoarthritic (OA) changes. Study Design: Systematic review; Level of evidence, 4. Methods: We searched PubMed, EMBASE, Cochrane Library, Scopus, and Google Scholar databases using keywords as well as Medical Subject Headings terms and Emtree using “(Open Bankart OR Bankart surgery) (NOT arthroscopy NOT revision)” for English-language studies. We conducted a systematic review in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Results: In total, 11 articles (10 with level 4 and 1 with level 3 evidence) including 563 patients (566 shoulders) were identified. The majority of patients were male (82%), the average age at the time of surgery was 27.4 years, and the mean follow-up was 11.5 years (range, 2.5-29 years). The most common functional score used was the Rowe score (95%) for the reported outcome measures, which showed good to excellent results (mean, 88.5 points). The overall recurrent instability rate, including dislocation and subluxation as a postoperative complication, was 8.5%. A total of 87% of patients were able to return to sport and work postoperatively. Overall, OA changes were reported in 33% of the patients, and the overall revision rate was 1%. Conclusion: Open Bankart repair exhibited favorable results, with a low postoperative instability rate. It is a reliable surgical procedure that allows high-demand patients to return to sport and work.

THE DISTRIBUTION OF THE MAIN RISK FACTORS IN PATIENTS WITH INTERMEDIATE-HIGH RISK PULMONARY EMBOLISM

The pulmonary embolism (PE) represents a medical condition with increasing incidence. The various clinical forms of PE have different prognosis, related to the presence of markers of right ventricle (RV) dysfunction (biochemical or imagistic). Material and method. In this study we included 82 consecutive patients with intermediate-high risk PE, assessing the main risk factors distribution. We divided the patients in two groups, study group - receiving thrombolytic therapy (ateplase (t-Pa)) associated to anticoagulation (unfractionated heparin (UFH)) – and control group – receiving anticoagulation alone -. The inclusion in study group was indicated by the high bleeding risk, in this group being included patients without contraindications for thrombolysis, patients without severe renal dysfunction and patients with body mass index (BMI) 18.5-29.9 kg/m2. We assessed the gender distribution in the two groups, the medium age distribution and the main PE risk factors in the two groups. Also, we assessed the effect of the both therapies on the hemodynamic instability rate on 7 day from admission (defined by systolic blood pressure (SBP) < 100 mmHg or a SBP drop >40 mmHg from inclusion value). The statistical analysis was made using SPSS program, by comparing the association between risk factors and the two groups, by Chi-squared test, while the gender and age distribution was made using the Shapiro Wilk test for the evenly data distribution and Wilk test (as the data were unevenly distributed). Results. We found no correlation between the risk factors and the study groups. There was no statistical significance regarding the gender distribution, but the medium age was higher in control group (61.82 y.o vs. 71.28 y.o, p < 0.001. Regarding the hemodynamic instability rate the Chi-squared test proved a statistical significant higher incidence in the control group (p = 0.03).

The Early Outcomes of BeGraft Peripheral Plus in Branched Endovascular Repair of Thoracoabdominal Aneurysms

Objective No bridging stent-graft (BSG) has been specifically designed for branched endovascular aortic repair (BEVAR) and therefore different “off-label” stent-grafts have been used. Recently, a third generation of balloon-expandable stent-graft has become available. Here we evaluate the outcomes of the BeGraft Peripheral Plus (B+) used as a BSG for internal/externalor inner branches during BEVAR. Materials and Methods Consecutive patients undergoing BEVAR using B+ as a BSG since its release in 2017 were included into the study. The primary endpoints were technical success and target vessel patency during follow-up. Secondary endpoints included the need for adjunct extension and relining of the BSG, branch instability rate, including occlusion, reinterventions for restonosis, kink, fracture, or endoleak (types 1 and 3). Results A total of 163 visceral branches in 46 patients were included with a median follow-up 15 months (4–36 months). Primary technical success was achieved in all visceral branches (69 inner branches and 94 internal/external branches) with the exception of 1 BSG that required serial dilatation until full expansion was achieved with overall branch patency was 98% at 2 years. An additional stent-graft was necessary in 35 branches (21%) following deployment of a B+ BSG to cover a longer bridging distance and optimize the distal and proximal sealing. Relining of B+ BSG was not routinely carried out during the index procedure and a self-expanding uncovered nitinol stent was necessary in only 3% of branches to smooth the distal transition zone between the BSG and target vessel. There were 4 events (2.4%) of branch related instability, including 2 occlusions and 2 late reinterventions for a partial in-stent-graft thrombosis. Conclusion Our study findings show satisfactory early outcomes of B+ as a BSG in BEVAR with low occlusion and reintervention rates. Extensions of BSG might be required to achieve adequate seal in the target vessels but routine relining BSG in branches was not required.

Aortic endograft and bridging stent-graft remodeling after branched endovascular aortic repair

Objectives The results of branched endovascular repair of thoracoabdominal aneurysms are mainly dependent on durability of the graft used. The purpose of this study was to evaluate postoperative aortic main body and bridging stent-graft remodeling, and their impact on bridging stent-graft instability at one year. Methods Computed tomoangiographies of 43 patients (43 aortic main body mated with 171 bridging stent-grafts) were analyzed before and after branched endovascular repair as well as after a follow-up of 12 months. Primary endpoint was aortic main body remodeling (migration >5 mm, shortening >5 mm, scoliosis >5° or lordosis >5°). Shortening was defined as a reduced length in the long axis, scoliosis as left-right curvature, and lordosis as antero-posterior curvature. Aortic main body remodeling, aneurysm sac changes, and bridging stent-graft tortuosity were evaluated to study their correlations and the impact on the bridging stent-graft instability. Results At 12 months, aortic main body remodeling was observed in 72% of the cases, migration in 39.5% (mean 5.21 mm), shortening in 41.9% (mean 5.79 mm), scoliosis in 58.1%, (mean 10.10°), lordosis in 44.2% (mean 5.78°). Migration, shortening, and scoliosis were more frequent in patients with larger aneurysms ( p = .005), while scoliosis was significantly more frequent in type II thoracoabdominal aneurysm ( p = .019). Aortic main body remodeling was significantly associated to bridging stent-graft remodeling (r: 0.3–0.48). The bridging stent-graft instability rate was 9.3%. Despite a trend toward significance ( p = .07), none of the evaluated aortic main body and bridging stent-graft changes were associated with bridging stent-graft instability at 12 months. Conclusions Aortic main body remodeling is frequent especially in large and extended thoracoabdominal aneurysm aneurysms. Aortic main body and bridging stent-graft remodeling was significantly correlated. While these geometric changes had no significant impact on bridging stent-graft instability at one year, a close long-term follow-up after branched endovascular repair could predict bridging stent-graft failures.

Testing the Systemic Model of Social Disorganization Theory in South Korean Neighborhoods: A Latent Class Growth Analysis Approach to Specifying Pathways to Homicide

This study examines the relationship between structural characteristics and homicide trajectories in South Korean neighborhoods utilizing the systemic model of social disorganization theory as an analytical lens. Group-based trajectory modeling of Korean homicide data across 229 municipal-level sub-national regions between 2008 and 2013 yielded three groups: high-decrease, moderate, and low-stable. The odds of belonging to the high and moderate groups compared to the low-stable group were significantly increased for communities with a higher-level divorce rate and residential instability rate. Social control was significant in the high-decrease group compared to the low-stable group, but had no mediating effect on this relationship.

COMPREHENSIVE PREVENTION OF INSTABILITY IN HIP REPLACEMENT FOR HIP FRACTURES AND THEIR CONSEQUENCES IN POSTMENOPAUSAL OSTEOPOROSIS IN MULTIPAROUS WOMEN

Objective: To reduce instability rate after hip replacement (HR) in postmenopausal osteoporosis in multiparous women. Methods: Analyzed data of HR performed by 126 multiparous women with postmenopausal osteoporosis and hip fractures and their consequences. In the main group (n=65; 51.6%) of patients prevention of instability of endoprosthesis components was carried out using the proposed measures, in the control group (n=61; 48.4%) of patients – with traditional approaches. Clinical and X-ray methods, densitometry, a comprehensive method of assessing hip function by Harris, statistical methods are used in the implementation of the work. Results: In the main group influenced by proposed approaches in the dynamics have seen a decrease in the frequency of osteoporosis and due to this – an increasing osteopenia. In addition, there was a decrease in the frequency of instability of endoprosthesis components compared to the control group from 14.8% to 4.6% (p<0.005). Conclusions: Rational operation planning, and its implementation taking into account the peculiarities of the current of osteoporosis, continuous medication and rational post-operative rehabilitation are effective ways to reduce the frequency of instability in hip replacement in considered pathology. Keywords: Postmenopausal osteoporosis, hip replacement, hip fractures, multiparous women, baseline treatment for osteoporosis

Outcomes of Arthroscopic Posterior Shoulder Stabilization in the Beach-Chair Versus Lateral Decubitus Position: A Systematic Review

Background: Arthroscopic posterior shoulder stabilization can be performed with patients in the beach-chair (BC) and the lateral decubitus (LD) positions; however, the impact of patient positioning on clinical outcomes has not been evaluated. Purpose: To compare clinical outcomes and recurrence rates after arthroscopic posterior shoulder stabilization performed in the BC and LD positions. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review using PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) guidelines was performed by searching PubMed, Embase, and the Cochrane Library for studies reporting the clinical outcomes of patients undergoing arthroscopic posterior shoulder stabilization in either the BC or LD position. All English-language studies from 1990 to 2017 reporting clinical outcomes after arthroscopic posterior shoulder stabilization with a minimum 2-year follow-up were reviewed by 2 independent reviewers. Data on the recurrent instability rate, return to activity or sport, range of motion, and patient-reported outcome scores were collected. Study methodological quality was evaluated using the Modified Coleman Methodology Score (MCMS) and Quality Appraisal Tool (QAT). Results: A total of 15 studies (11 LD, 4 BC) with 731 shoulders met the inclusion criteria, including 626 shoulders in the LD position (mean patient age, 23.9 ± 4.1 years; mean follow-up, 37.5 ± 10.0 months) and 105 shoulders in the BC position (mean patient age, 27.8 ± 2.2 years; mean follow-up, 37.9 ± 16.6 months). There was no significant difference in the overall mean recurrent instability rate between the LD and BC groups (4.9% ± 3.6% vs 4.4% ± 5.1%, respectively; P = .83), with similar results in a subanalysis of studies utilizing only suture anchor fixation (4.9% ± 3.6% vs 3.2% ± 5.6%, respectively; P = .54). There was no significant difference in the return-to-sport rate between the BC and LD groups (96.2% ± 5.4% vs 88.6% ± 9.1%, respectively; P = .30). Range of motion and other patient-reported outcome scores were not provided consistently across studies to allow for statistical comparisons. Conclusion: Low rates of recurrent shoulder instability and high rates of return to sport can be achieved after arthroscopic posterior shoulder stabilization in either the LD or the BC position. Additional long-term randomized trials comparing these positions are needed to better understand the potential advantages and disadvantages of surgical positioning for posterior shoulder stabilization.

Recurrence of Patellar Instability in Adolescents Undergoing Surgery for Osteochondral Defects Without Concomitant Ligament Reconstruction

Background: First-time patellar dislocation with an associated chondral or osteochondral loose body is typically treated operatively to address the loose fragment. The incidence of recurrent instability in this patient population if the medial patellofemoral ligament (MPFL) is not reconstructed is unknown. Purpose: To determine the recurrent instability rate in patients undergoing surgery for patellar instability with chondral or osteochondral loose bodies, as well as to identify and stratify risk factors for recurrent instability. Study Design: Case series; Level of evidence, 4. Methods: This was a retrospective analysis of adolescent patients treated operatively for acute patellar dislocation with associated chondral or osteochondral loose bodies between 2010 and 2016 at a single pediatric level I trauma center with minimum 2-year follow-up. Potential demographic, injury-related, radiographic, and surgical risk factors were recorded. The primary outcome variable was recurrent subluxation and/or dislocation. Secondary outcome variables included need for additional procedures, Kujala score, Single Assessment Numerical Evaluation (SANE) score, and patient satisfaction. Results: Forty-one patients were included. In total, 61% experienced recurrent instability at a mean follow-up of 4.1 years and 39% required subsequent MPFL reconstruction. Tibial tubercle-trochlear groove (TT-TG) distance greater than 15 mm was a risk factor for recurrent instability ( P = .03). Patients with TT-TG distance greater than 15 mm and greater than 20 mm had recurrent instability rates of 75% and 86%, respectively. MPFL repair did not reduce the rate of recurrent instability ( P = .87). Recurrent instability was associated with significantly worse mean Kujala (93.9 vs 83.0; P = .01), SANE (88.9 vs 73.1; P = .01), and patient satisfaction scores (9.4 vs 7.3; P = .002). Conclusion: If the MPFL is not reconstructed during index loose body treatment, children have a 61% recurrent instability rate. Patients with TT-TG distance greater than 15 mm, and particularly greater than 20 mm, are at highest risk for recurrent instability.

Prosthetic Arthroplasty of Proximal Interphalangeal Joints for Treatment of Osteoarthritis and Posttraumatic Arthritis: Systematic Review and Meta-Analysis Comparing the Three Ulnar Digits With the Index Finger

Background: It is common teaching that treatment of index finger alone is a relative contraindication for arthroplasty of the proximal interphalangeal joint (PIPJ). However, limited data exist reporting the digit-specific complication of PIPJ arthroplasty for the treatment of osteoarthritis or posttraumatic arthritis. The purpose of this article is to perform a systematic review and meta-analysis of the literature to assess whether the 3 ulnar digits may bear a similar instability and complication profile. Methods: Systematic searches of the MEDLINE, EMBASE, and Cochrane computerized literature databases were performed for PIPJ arthroplasty specifying by digit. We reviewed both descriptive and quantitative data to: (1) report aggregate instability and instability-related complications after non-index digit PIPJ arthroplasty; and (2) perform statistical testing to assess relative rates by digit and compared with index digits. Results: Computerized search generated 385 original articles. Five studies reporting digit-specific instability-related outcomes of silicone, pyrocarbon, or metal surface arthroplasty on 177 digits were included in the review. Meta-analysis demonstrated a 29% instability rate for long digits (n = 65), 6% for ring digits (n = 53), and 6% for small digits (n = 17), compared with 33% for index digits (n = 42). There was no difference in the overall deformity, instability, and complication rates of long versus index fingers ( P = .65). Conclusions: Instability-related deformity and complication rates of long finger PIPJ arthroplasty may not be different from that of the index finger. Treatment of the long finger may be a relative contraindication to PIPJ arthroplasty. Future biomechanical and clinical studies are needed.

Stability of the Syndesmosis After Posterior Malleolar Fracture Fixation

Background: We sought to define the rate of syndesmotic instability after anatomic reduction of the posterior malleolus when posterior stabilization of a trimalleolar or trimalleolar equivalent ankle fracture was chosen vs when a supine position and initially conservative management of the posterior elements was chosen. Methods: The types of syndesmotic and posterior malleolar fixation used to treat adult patients with ankle fractures involving the posterior malleolus at our level I trauma center were retrospectively assessed (N = 198). Specifically, both bimalleolar and trimalleolar fractures were included. Exclusion criteria included pilon fractures, trimalleolar fractures with Chaput fragments, and neurologic injury. Demographics, fracture classification, initial operative position, medial clear space, and posterior malleolar fragment size were recorded for each fracture. Results: In total, 151 patients (76.3%) were initially positioned supine, 27.2% of whom had syndesmotic instability requiring operative stabilization. Almost 25% of supine patients also underwent posterior malleolar stabilization for posterior instability. Overall, 73 (48.3%) patients who were initially treated in the supine position needed some form of additional stabilization. Forty-seven patients (23.7%) were initially positioned prone. Syndesmotic stability was restored in 97.9% of these patients. This 2.1% rate of instability vastly differs from the 13-fold higher syndesmotic instability rate observed in the supine group ( P < .001). Conclusion: Our data demonstrate that the rate of syndesmotic instability was reduced in trimalleolar and trimalleolar equivalent fractures when prone positioning and direct fixation of the posterior malleolus were first performed. Using traditional preoperative estimates of posterior stability to determine the need for posterior malleolar fixation may be inadequate since almost a quarter of patients treated supine received posterior stabilization. Level of Evidence: Level III, retrospective comparative series.
