RESUMO
Biconcave (B2) glenoids, characterized by significant posterior glenoid bone loss and a biconcave wear pattern, are a challenging pathology in shoulder surgery. Significant bone defects present in B2 glenoids increases the risk of complications and rates of failure for operative patients with glenohumeral osteoarthritis. Diagnosing this entity is of pivotal importance, and can be accomplished with imaging and a comprehensive clinical investigation. There are no clear-cut guidelines for management, but options include hemiarthroplasty, anatomic total shoulder arthroplasty, and reverse shoulder arthroplasty. In recent years, modern techniques such as corrective reaming, bone grafts, and the use of augmented components have improved patient outcomes. Educating prospective patients is essential for reaching a shared management decision, setting appropriate expectations, and optimizing prognostic outcomes.
RESUMO
Reverse total shoulder arthroplasty (RTSA) is widely popular among shoulder surgeons and patients, and its prevalence has increased dramatically in recent years. With this increased use, the indicated pathologies associated with RTSA are more likely to be encountered, and challenging patient presentations are more likely to be seen. One prominent challenging presentation is RTSA patients with severe glenoid bone loss. Several techniques with varying degrees of invasiveness, including excessive reaming, alternate centerline, bone grafting, and patient-specific implants (PSIs), have been developed to treat patients with this presentation. PSI treatment uses a three-dimensional reconstruction of a computed tomography scan to design a prosthetic implant or component customized to the patient's glenoid morphology, allowing compensation for any significant bone loss. The novelty of this technology implies a paucity of available literature, and although many studies show that PSIs have good potential for solving challenging shoulder problems, some studies have reported questionable and equivocal outcomes. Additional research is needed to explore the indications, outcomes, techniques, and cost-efficiency of this technology to help establish its role in current treatment guidelines and strategies.
RESUMO
Several surgical procedures have been proposed to address anterior glenohumeral instability, which is one of the most common complaints in the general population. The remplissage, first described in early 2000s, is a procedure performed simultaneously with the arthroscopic Bankart repair to correct large, engaging Hill-Sachs lesions (HSLs). This procedure stabilizes the joint by tenodesing the infraspinatus tendon into the HSL to fill and disengage the defect. This procedure gained popularity because it has relatively low risk and is able to improve shoulder stability while being less invasive than other bone-blocking procedures. The remplissage has become a valuable add-on technique that can substantially improve outcomes in unstable patients undergoing arthroscopic Bankart repair. Nevertheless, several studies in the literature have raised concerns regarding its efficacy in critically unstable patients and the potential range of motion limitations that can arise postoperatively. Additional comparative studies and trials should be conducted to appropriately establish the role of remplissage in treating anterior instability, especially in patients with critical bone loss.
RESUMO
Background: Patients with diabetes mellitus (DM) are known to be predisposed to many complications in the lower extremities such as neuropathy, peripheral artery disease (PAD) and infection. Diabetic foot ulcers are complications of diabetes that can lead to lower extremity amputations, re-amputations and high mortality rates.Purpose: The aim of this study is to evaluate the risk factors associated with higher re-amputation rates in diabetic foot disease.Research Design: This is a mono-centric retrospective comparative study.Study Sample: the study included 136 patients, with a total of 193 procedures (111 primary amputations and 82 re-amputations) between 2011 and 2021.Data Analysis: The t-student test and Spearman correlation were used to look for mean differences and any relevant association, respectively. Multivariate logistic regression analysis was computed to look for independent variables.Results: Twenty-two (27%) and 60 (50%) of those who had major and minor amputations, respectively, had a re-amputation (p = 0.006). Besides diabetes (89%), the commonest risk factor associated with amputation was hypertension (86.7%), be it for primary amputation or re-amputation, followed by peripheral (PAD) and coronary artery diseases. Only three risk factors showed independent correlation with re-amputation; chronic kidney disease (r = 15%, p = 0.03), smoking (r = 15%, p = 0.03), and simultaneous presence of DM + PAD (r = 13.7%, p = 0.05).Conclusions: Factors that were significantly correlated with increased re-amputation rates have a clear pathologic pathway that affects vascularity and wound healing. Further studies should be aimed at developing a clear scoring system that can be used to stratify patient for re-amputation risk, and to better predict the results according to the severity of diabetes.
RESUMO
Meniscal suturing has become the gold standard when it comes to meniscal tears in vascularized areas, especially in the younger population. The all-inside meniscal suturing technique has gained popularity in the past year due to decreased operative time as well as decreased risk of adverse events, as compared to other modalities. However, several complications have been reported with the all-inside technique, including soft tissue and neurovascular injury. This is the first case reporting a semimembranosus tendon entrapment following an all-inside medial meniscal suture. Being aware of such complications is crucial in order to avoid them and treat them promptly should they arise.
