Allograft Use in Shoulder Surgery: Instability and Rotator Cuff.

Shoulder instability and rotator cuff pathology can provide a challenging problem, especially in the revision setting. Allograft use in primary or revision surgical intervention for shoulder instability and rotator cuff tear may be a valuable resource. This paper reviews allograft tissue use in shoulder surgery for instability and rotator cuff tear.

Visualization of rotator cuff tear morphology by radial magnetic resonance imaging.

The objective of this study was to investigate whether rotator cuff tear morphology could be visualized using radial MRI. We retrospectively investigated 52 shoulders that underwent preoperative MRI and arthroscopy for a complete rotator cuff tear. The tear length and width were measured using oblique coronal, axial, and radial MRI. Arthroscopic findings were compared with the tear morphology. Tear morphology was visualized using oblique coronal and axial MRI for 24 of the 52 shoulders (46%), and radial MRI...

Factors Associated with Atraumatic Posterosuperior Rotator Cuff Tears.

Certain metabolic factors have been proposed as risk factors for a posterosuperior rotator cuff tear. Although metabolic syndrome is of increasing concern in industrialized societies, little information exists regarding its association with posterosuperior rotator cuff tears. The purpose of this study was to determine the risk factors for an atraumatic posterosuperior rotator cuff tear, including metabolic factors and metabolic syndrome.

Rotator cuff tear following long-standing axillary neuropathy in a female motocross racer.

A 'terrible triad' of anterior shoulder dislocation, axillary nerve damage and rotator cuff tear has been previously described. However, we are unaware of any report of anterior shoulder dislocation, humeral fracture, axillary neuropathy and subsequent rotator cuff tear requiring surgery when the axillary neuropathy was deemed permanent. We report the case of a 20-year-old woman who fell in a motocross accident and had an anterior shoulder dislocation, humeral fracture and axillary neuropathy. The fracture ...

Integrity of the Untorn Articular-Sided Tendon in Bursal-Sided Partial-Thickness Rotator Cuff Tear: A Comparative Study of Apoptotic Activity in Torn and Untorn Layers.

Conversion to full-thickness tear in partial-thickness rotator cuff tears (PTRCTs) is based on the quality and thickness of the normal-looking untorn rotator cuff layer. However, whether the untorn tendon is a healthy tissue remains to be elucidated.

Characteristics of the patients with delaminated rotator cuff tear.

The purpose of this study was to analyze factors relating to delamination in full-thickness rotator cuff tears.

A Rotator Cuff Tear Concomitant With Shoulder Stiffness Is Associated With a Lower Retear Rate After 1-Stage Arthroscopic Surgery.

Few studies have reported on the radiological characteristics and repair integrity of coexistent rotator cuff tears (RCTs) and shoulder stiffness after simultaneous arthroscopic rotator cuff repair and capsular release.

Evaluating the Outcomes of Rotator Cuff Repairs With Polytetrafluoroethylene Patches for Massive and Irreparable Rotator Cuff Tears With a Minimum 2-Year Follow-up.

Massive and irreparable rotator cuff tears are difficult to manage surgically. One technique is to use a synthetic polytetrafluoroethylene (PTFE) patch to bridge the tear. However, there is little information regarding the outcomes of this procedure.

The pathogenesis and management of cuff tear arthropathy.

Massive rotator cuff tears may lead to the development of cuff tear arthropathy (CTA). Although this pathology has been recognized for more than 150 years, treatment strategies have continued to evolve. During the last decade, there has been increased understanding of the molecular and cellular changes that govern rotator cuff tear outcomes and development of new treatment strategies to repair or reconstruct the rotator cuff. These have included an expansion of the use of arthroscopic double-row transosseou...

Rotator cuff failure after surgery: an all-arthroscopic transosseous approach.

Tear recurrence is considered the main complication of a rotator cuff repair. The best arthroscopic technique has not yet been established. The aim of the present study was to evaluate, from a clinical and a radiological standpoint, the all-arthroscopic transosseous rotator cuff repair with cortical lateral augmentation, performed in the setting of a revision surgery.

Prevalence and Risk Factors of Neuropathic Pain in Patients with a Rotator Cuff Tear.

Until now, few studies had investigated the neuropathic pain component in patients with a rotator cuff tear (RCT).

In vivo dynamic acromiohumeral distance in shoulders with rotator cuff tears.

There are no previous studies on the acromiohumeral distance in shoulders with large-to-massive full-thickness rotator cuff tears. In this study, the acromiohumeral distance in rotator cuff tear and healthy shoulders was measured using 3D-to-2D model-to-image registration techniques.

Editorial Commentary: Rotator Cuff Surgery Planning: Yet Another Reason for Orthopedic Surgeons to Learn to Use Ultrasound….

Several factors that affect the healing rate of shoulder rotator cuff tears have been elucidated, including tear size, degree of retraction, and degree of muscle atrophy. Identifying these factors preoperatively is critical for appropriate surgical planning and patient counseling. Ultrasound can be used to predict rotator cuff stiffness, which could result in a way to better plan for rotator cuff surgeries.

The effects of rotator cuff tear on shoulder proprioception.

To evaluate the effects of rotator cuff tear (RCT) and its severity on shoulder proprioception.

Subacromial space volume in patients with rotator cuff tear: The effect of surgical repair.

The aim of this study was to evaluate the effect of the rotator cuff tear repair on subacromial space volume.

Arthroscopic treatment for intratendinous rotator cuff tear results in satisfactory clinical outcomes and structural integrity.

This study aimed to evaluate the clinical outcomes and structural integrity of arthroscopic repair of intratendinous rotator cuff tear.

Fatty Infiltration Is a Prognostic Marker of Muscle Function After Rotator Cuff Tear.

Massive rotator cuff tears (RCTs) begin as primary tendon injuries and cause a myriad of changes in the muscle, including atrophy, fatty infiltration (FI), and fibrosis. However, it is unclear which changes are most closely associated with muscle function.

Rotator Cuff Tear.

A novel remaining tendon preserving repair technique leads to improved outcomes in special rotator cuff tear patterns.

The purpose of this study was to identify the tear pattern that could be anatomically repaired by preserving the remaining tendon on footprint and evaluate clinical outcomes of patients who underwent remaining tendon preserving cuff repair.

Modeling a rotator cuff tear: Individualized shoulder muscle forces influence glenohumeral joint contact force predictions.

Rotator cuff tears in older individuals may result in decreased muscle forces and changes to force distribution across the glenohumeral joint. Reduced muscle forces may impact functional task performance, altering glenohumeral joint contact forces, potentially contributing to instability or joint damage risk. Our objective was to evaluate the influence of rotator cuff muscle force distribution on glenohumeral joint contact force during functional pull and axilla wash tasks using individualized computational...

Upper body kinematic and muscular variability in response to targeted rotator cuff fatigue.

The rotator cuff muscles are prominent stabilizers of the shoulder and are vulnerable to muscle fatigue. Rotator cuff fatigue may result in subacromial impingement (SAI) through the superior translation of the humeral head. Scapular changes have been reported inconsistently, but may prevent SAI. The purpose of this study was to quantify changes in scapular kinematics, as well as muscle activity during glenohumeral motions following targeted rotator cuff fatigue. Ten healthy men completed four planar glenohu...

Erratum to: What Influence Does Progression of a Nonhealing Rotator Cuff Tear Have on Shoulder Pain and Function?

Effects of Tendon Degeneration on Predictions of Supraspinatus Tear Propagation.

Rotator cuff tendons undergo degeneration with age, which could have an impact on tear propagation. The objective of this study was to predict tear propagation for different levels of tissue degeneration using an experimentally validated finite element model of a supraspinatus tendon. It was hypothesized that greater amounts of degeneration will result in tear propagation at lower loads than tendons with less degeneration. Using a previously-validated computational model of supraspinatus tendon, 1-cm tears ...

Large Critical Shoulder Angle Has Higher Risk of Tendon Retear After Arthroscopic Rotator Cuff Repair.

The critical shoulder angle (CSA) is the angle created between the superior and inferior bone margins of the glenoid and the most lateral border of the acromion. A few studies recently investigated the relation between CSA and functional outcomes after rotator cuff repair. However, there is a lack of research investigating the effect of CSA on postoperative tendon integrity after rotator cuff repair.
