Radial and median nerves distal peripheral tension after reverse shoulder arthroplasty: a cadaveric study.

Background: Peripheral nerve injury is a recognized complication after reverse shoulder arthroplasty (RSA) that has mainly been studied at the level of the brachial plexus and its proximal branches. However, the impact of RSA on distal peripheral nerves and the influence of elbow and wrist position is not known. This cadaveric study aimed to analyze the effect of RSA implantation and upper limb position on tension in the distal median and radial nerves.

Accuracy of Anterior Shoulder Injections Without Image Guidance: A Prospective Controlled Study.

Introduction: This study aims to assess the accuracy of glenohumeral joint injections through an anterosuperior approach using anatomical landmarks as a guide and arthroscopic visualization as the control method and to evaluate whether there is any association between accuracy, the physicians training, and the patient's pathology.

Materials And Methods: A sample size of 124 patients was calculated. A prospective cohort study including 164 consecutive patients was conducted.

Leukocyte-Poor Platelet-Rich Plasma as an Adjuvant to Arthroscopic Rotator Cuff Repair Reduces the Retear Rate But Does Not Improve Functional Outcomes: A Double-Blind Randomized Controlled Trial.

Background: Whether the use of PRP as an adjuvant of rotator cuff repairs leads to improved tendon healing and better functional outcomes remains unclear in clinical evidence.

Purpose: The main purpose of this study was to assess whether the use of leukocyte-poor platelet-rich plasma (LP-PRP) as an adjuvant to arthroscopic rotator cuff repair (ARCR) decreases the rate of retears compared with a control group. The secondary objective was to analyze whether LP-PRP improves patient-reported outcomes.

Shoulder Stabilization Technique Using the Medial Glenohumeral Ligament in Patients With the Buford Complex.

The Buford complex is an anatomic variation defined as the association of a cordlike middle glenohumeral ligament (MGHL) and an absent anterosuperior labrum. It can be challenging to properly identify on preoperative imaging and remains mostly an arthroscopic finding. It may, however, lead to problematic situations when encountered during an arthroscopic soft-tissue stabilization procedure, as the treatment of choice in such cases is a bone block.

An Unusual Case of Onlay Reverse Shoulder Arthroplasty Disassembly Due to Cement Interposition. A Case Report.

Introduction: Reverse shoulder arthroplasty (RSA) complication rates range between 1.4% and 28% depending on the nature of the indication. Even though glenosphere dissociation is the third most frequent complication after RSA, with an incidence that can rise to just over 12%, there is no evidence in the literature describing the disassembly between the humeral stem and its metaphysics.

The role of bone morphology of the greater tuberosity and lateral acromion on subacromial space during scaption: a three-dimensional dynamic simulation analysis.

Background: The bone morphology of the greater tuberosity and lateral acromion plays a central role in subacromial impingement syndrome. The critical shoulder angle (CSA) and greater tuberosity angle (GTA) are two-dimensional measurement parameters that have been validated to evaluate it radiologically. These markers are, however, static and don't consider the dynamic effect of glenohumeral motion.

Glenoid index: a new risk factor for recurrence of glenohumeral instability after arthroscopic Bankart repair.

Background: The glenoid index (GI) (glenoid height to width ratio) has been shown to be a risk factor for instability in young healthy athletes. Nevertheless, whether the altered GI is a risk factor for recurrence after a Bankart repair remains unknown.

Methods: Between 2014 and 2018, 148 patients ≥ 18 years old with anterior glenohumeral instability underwent a primary arthroscopic Bankart repair in our institution.

Functional outcomes after arthroscopic double button fixation of distal clavicular fractures in athletes.

Unlabelled: Distal third clavicle fractures are a frequent pathology in young, active patients, accounting for 30% of all clavicle fractures. There are several treatments available, which range from orthopedic management to surgical treatment with various options including: locking plates, tension bands and button fixation. The aim of this study was to evaluate the clinical and radiologic results of a group of patients treated with the arthroscopic double button fixation technique and, secondly, to analyze the complications and the rate of return to sports.

[Benefits of arthroscopic rotator cuff repair in octogenarians. Analysis of functional results and complications].

Introduction: There is a lack of information in the literature on the results of arthroscopic rotator cuff repair in patients older than 80 years. The purpose of this study was to evaluate a consecutive series of patients with rotator cuff tears who underwent arthroscopic rotator cuff repair.

Methods: Retrospective analysis of patients older than 80 years who underwent arthroscopic rotator cuff repair between June 2004 and January 2016.

Subacromial Platelet-Rich Plasma Injections Produce Significantly Worse Improvement in Functional Outcomes in Patients With Partial Supraspinatus Tears Than in Patients With Isolated Tendinopathy.

Purpose: To compare the effect of subacromial leukocyte-rich platelet-rich plasma (PRP) injections in patients with isolated rotator cuff tendinopathy (RCT) and those with partial-thickness rotator cuff tears (PTRCTs) based on functional outcomes, pain improvement, sleep disturbances, and return to sports.

Methods: Between November 2019 and March 2021, 150 patients underwent PRP injections at our institution for refractory rotator cuff tendinopathy and partial rotator cuff tears (105 RCTs and 45 PTRCTs). The American Shoulder and Elbow Surgeons (ASES) score, the visual analog scale (VAS) for pain, the Single Assessment Numeric Evaluation (SANE) and The Pittsburgh Sleep Quality Index were evaluated at 2-, 6-, and 12-month follow-up.

Background: Literature is scarce regarding the influence of psychological readiness on return to sports after shoulder instability surgery.

Purpose: To evaluate the predictive ability of the Shoulder Instability-Return to Sport after Injury (SIRSI) score in measuring the effect of psychological readiness on return to sports and to compare it between athletes who returned to sports and athletes who did not return to sports.

Study Design: Cohort study; Level of evidence, 2.

Total knee replacement in octogenarians, Is age a determining factor in predicting complications? a retrospective cohort study.

Introduction: Given the increase in life expectancy in the general population of our country, there is an exponential increase since the last decades of functional older adults who undergo total knee replacement (TKR). There is a direct relationship between the increase in age and the prevalence of both functional and cognitive disabling chronic diseases, however, little we know about whether age is an independent factor in predicting worse functional outcomes and readmissions after TKR. The objective of this study was to evaluate the clinical-functional results and unplanned readmissions within the first 90 postoperative days in patients older than 80 years compared with a control group of patients younger than 80 years.

Background: There is a lack of information regarding the reasons why patients do not return to sports after an arthroscopic Bankart repair and whether there is a relationship between return to sports and functional outcomes.

Purpose: To evaluate the reasons why competitive athletes who underwent arthroscopic Bankart repair did not return to sports and whether there was a relationship between returning to sports and postoperative outcome scores and complications.

Study Design: Cohort study; Level of evidence, 3.

Salvage procedure for cut-through after surgical fixation of trochanteric fractures with TFN.

Introduction: Closed reduction and fixation using a cephalomedullary nail represents the accepted management of unstable intertrochanteric fractures. Cut-through has been described as a complication associated with the treatment. Although a hip arthroplasty may be the most predictable revision method, a non-prosthetic option can lead to similar results.

Subacromial Platelet-Rich Plasma Injections Decrease Pain and Improve Functional Outcomes in Patients With Refractory Rotator Cuff Tendinopathy.

Purpose: The purpose of this study was to evaluate the effect of subacromial platelet-rich plasma (PRP) injections in patients with refractory rotator cuff tendinopathies based on pain improvement, functional outcomes, sleep disturbances, and return to sports to the same level as before the injury.

Methods: Between March 2019 and October 2019, 50 patients with rotator cuff tendinopathy refractory to conservative treatment were treated with one subacromial PRP injection in our institution. Magnetic resonance imaging was performed in all patients to confirm diagnosis.

The Latarjet Procedure Without Remplissage Is Effective to Restore Stability in Athletes With Glenoid Bone Defects Greater Than 25% and Off-Track Hill-Sachs Lesions.

Purpose: There were 2 main purposes in this study: (1) to report on clinical outcomes of the Latarjet procedure without remplissage in athletes with glenoid bone defects greater than 25% and off-track Hill-Sachs lesions and (2) to determine whether the isolated Latarjet procedure converted off-track Hill-Sachs lesions to on-track Hill-Sachs lesions as measured on computed tomography (CT).

Methods: During the study period, a total of 29 athletes who had anterior glenohumeral instability with glenoid bone defects greater than 25% and off-track Hill-Sachs lesions, who underwent Latarjet surgery, and who had a minimum follow-up period of 24 months were included in this study. The glenoid track was analyzed before and 3 months after the procedure using 3-dimensional CT.

Radius shortening as a limiting factor for closed reduction in pediatric forearm fractures.

Introduction: Diaphyseal forearm fractures in skeletally immature patients are common injuries that account for 30% of upper extremity fractures in this age group. There are cases with unstable injuries or unacceptable reductions, in which surgical resolution by reduction and stabilisation with percutaneous elastic endomedullary nailing is indicated. One of the advantages of this system is that it avoids an approach to the fracture site, allowing closed reduction in the vast majority of fractures.

[Tuberculosis in the proximal humerus. A rare diagnosis in joint infections].

The incidence of osteoarticular TB is much lower than that of the lung, representing 1-2% of TB cases and 10% of extrapulmonary TB cases, so it is often not considered for the differential diagnosis of patients with joint disease. Its diagnosis is difficult and is based on clinical, radiologica l, bacteriological and histological findings. Extrapulmonary lesions are paucibacillary and specimens, in most cases, difficult to obtain, so the diagnosis is often simply presumptive.

High Rate of Return to Sports and Low Recurrences With the Latarjet Procedure in High-Risk Competitive Athletes With Glenohumeral Instability and a Glenoid Bone Loss <20.

Purpose: To analyze return to sports, functional outcomes, and complications following the Latarjet procedure in competitive athletes with anterior glenohumeral instability and glenoid bone loss <20%.

Methods: All the included patients were operated between 2010 and 2016. The inclusion criteria were competitive athletes with anterior glenohumeral instability, a glenoid bone defect <20% who participated in contact sports, forced overhead sports, or had a previous failed Bankart repair and had a minimum 2 years' follow-up.

Coracoclavicular Double-Button Fixation of Displaced Lateral Clavicular Fracture in a Patient without Coracoid Process.

Background: Displaced distal clavicular fractures are generally operated on because of the high nonunion rate after nonoperative treatment. Several surgical techniques have been developed to reduce the nonunion rate and improve functional outcomes. One of them is closed reduction and minimally invasive coracoclavicular double-button fixation, which requires the integrity of the coracoid process to be performed.
