Diagnosing the direction of shoulder instability in rugby players.

The muscular characteristics of rugby players may make diagnosing the direction of shoulder instability and labral pathology challenging. This study aimed to assess the accuracy of clinical examination and specifically instability tests, in diagnosing the direction of shoulder instability in rugby players. One-hundred-and-forty rugby players, who had undergone a shoulder stabilization procedure, over a 55-month period, were included in this study.

Surgical repair and rehabilitation of a ruptured pectoralis major muscle in a professional footballer - A case report.

Background: Pectoralis Major ruptures normally occur in activities and sports such as powerlifting and American football or rugby. It is a rarely reported phenomena in professional footballers. Surgery is normally considered the choice of management to enable a safe return to play with conservatively managed ruptures often resulting in significant strength deficits.

Cardiorespiratory considerations for return-to-play in elite athletes after COVID-19 infection: a practical guide for sport and exercise medicine physicians.

SARS-CoV-2 is the causative virus responsible for the COVID-19 pandemic. This pandemic has necessitated that all professional and elite sport is either suspended, postponed or cancelled altogether to minimise the risk of viral spread. As infection rates drop and quarantine restrictions are lifted, the question how athletes can safely resume competitive sport is being asked.

In Vivo Randomized Controlled Study of the Bone Response of All-Suture Anchors and Biocomposite Anchors.

Background: Suture anchors are widely used for labral reconstruction surgery. However, there has been some concern over the development of osteolysis around the anchor. This has been reported for both biocomposite and all-suture anchors, but they have not been compared directly in vivo.

Failed Latarjet surgery: why, how, and what next?

Background: The Latarjet procedure is an established and popular procedure for recurrent anterior shoulder instability; however, to our knowledge, few studies have reported on the outcomes of revision for failed Latarjet surgery. We reviewed the causes and management of recurrent instability after previous Latarjet stabilization surgery. The outcomes of revision surgery were also evaluated.

The combined shoulder assessment: a convenient method for obtaining equivalent outcome scores.

Background: Outcome scores are useful tools with respect to quantifying how pain and limitations in strength and movement affect the patient's functionality and lifestyle. Three shoulder outcome methods [Oxford, Constant and QuickDASH (Disability of the Arm, Shoulder and Hand)] are commonly used in practice but collectively consist of 34 questions, taking approximately 7 min to complete. We have developed a concise shoulder assessment to derive three equivalent outcome scores in a 12-item patient-reporting questionnaire.

A four-strain probiotic exerts positive immunomodulatory effects by enhancing colonic butyrate production in vitro.

Poorly formulated probiotic supplements intended for oral administration often fail to protect bacteria from the challenges of human digestion, meaning bacteria do not reach the small intestine in a viable state. As a result, the ability of probiotics to influence the human gut microbiota has not been proven. Here we show how (i) considered formulation of an aqueous probiotic suspension can facilitate delivery of viable probiotic bacteria to the gut and (ii) quantitate the effect of colonisation and proliferation of specific probiotic species on the human gut microbiota, using an in-vitro gut model.

Recurrence After Arthroscopic Labral Repair for Traumatic Anterior Instability in Adolescent Rugby and Contact Athletes.

Background: Traumatic glenohumeral dislocation of the shoulder is one of the most common shoulder injuries, especially among adolescent athletes. The treatment of instability for young athletes continues to be controversial owing to high recurrence rates.

Purpose: To investigate the recurrence rate of shoulder instability after arthroscopic capsulolabral repair for adolescent contact and collision athletes.

Arthroscopic repair of bony Bankart lesions in collision athletes.

Background: The present study aimed to report the outcomes of acute and subacute arthroscopic bony Bankart repairs in collision athletes.

Methods: We reviewed 22 consecutive rugby players with traumatic anterior glenohumeral instability who underwent arthroscopic bony Bankart repair within 4 months of injury over a 2-year period. All lesions were less than 25% of the glenoid bony area.

The Rockwood classification in acute acromioclavicular joint injury does not correlate with symptoms.

Purpose: Rockwood classified acromioclavicular (AC) joint injuries by displacement of the joint on radiographs. This classification has driven the management dogma of acute AC dislocation. The correlation between Rockwood grade and symptoms has not been described in acute injury.

3D Printed Anchoring Sutures for Permanent Shaping of Tissues.

Sutures are one of the most widely used devices for adhering separated tissues after injury or surgery. However, most sutures require knotting, which can create a risk of inflammation, and can act as mechanically weak points that often result in breakage and slipping. Here, an anchoring suture is presented with a design that facilitates its propagation parallel to the suturing direction, while maximizing its resistive force against the opposite direction of external force to lock its position in tissues.

Neuralgic amyotrophy is not the most common neurologic disorder of the shoulder: a 78-month prospective study of 60 neurologic shoulder patients in a specialist shoulder clinic.

Background: Neuralgic amyotrophy (NA) was first described in 1948. Traditional literature describes a painful attack with sudden onset, followed by paresis, with varied outcomes. Recent studies have suggested NA is currently underdiagnosed.

Optimal electrode design: Straight versus perimodiolar.

The electrode in a cochlear implant (CI) system is a key factor in hearing performance as it is the interface between the device and the auditory pathway of the recipient. The first CI electrodes were straight and thus adopted a lateral wall position. Subsequent innovations include: perimodiolar electrodes designed to lie adjacent to the modiolar wall and thus to provide more spatially-focused stimulation of the spiral ganglion cells; shorter atraumatic straight electrodes for combined electric and acoustic (hybrid) stimulation.
