Background: Functionally irreparable rotator cuff tears (FIRCTs) present an ongoing challenge to the orthopedic surgeon. The aim of this systematic review was to critically compare the outcomes of three latissimus dorsi tendon transfer (LDT) techniques and two superior capsular reconstruction (SCR) techniques in treatment of FIRCTs.

Methods: A systematic review of studies evaluating the outcome of FIRCT treatment was performed via a search of four databases in April 2020. Read More

Purpose: To compare clinical and radiographic results of arthroscopic rotator cuff repair (ARCR) with biceps rerouting (BR) and those of conventional repair for semirigid, large-to-massive rotator cuff tear.

Methods: We prospectively collected data of 111 patients who underwent either ARCR + BR (n = 59, group 1) or only ARCR (n = 52, group 2) for semirigid, large-to-massive rotator cuff tear between January 2016 and December 2018. We comparatively analyzed both groups with respect to preoperative factors including concomitant lesions of the long head of the biceps tendon (LHBT). Read More

Introduction: Shoulder pain is one of the common musculoskeletal complaints of the patients with spinal cord injury. Corticosteroid injection to the subacromial bursa is one of the confirmed therapies which can be guided by anatomic landmarks or ultrasound. This study is aimed to compare these two methods to find the one with the highest therapeutic impact. Read More

International Spine Pain & Performance Center, Washington, DC, USA.

Objective: The objective of this study was to determine the effect of axillary peripheral nerve stimulation (PNS) on pain reduction in patients with chronic shoulder pain. Chronic shoulder pain was defined as pain greater than six months originating from any of the following and not the result of a stroke: subacromial impingement syndrome/rotator cuff pathology, glenohumeral joint arthritis, acromioclavicular joint arthritis, adhesive capsulitis, or biceps tendinopathy.

Materials And Methods: Eight adult patients with chronic shoulder pain, as defined above, who either did not respond to surgical intervention or who were deemed not ideal surgical candidates underwent permanent axillary PNS therapy. Read More

Background: Although the instability severity index score (ISIS) is widely used to predict recurrence after arthroscopic anterior instability surgery, its reliability, especially on the weightings and cutoff values, is questionable. The goal of the current retrospective study was to investigate recurrence after arthroscopic capsulolabral reconstruction to evaluate whether each domain of the ISIS has the appropriate predictive power for recurrence by using logistic regression analyses with odds ratios (ORs).

Methods: This study included 120 consecutive patients who underwent arthroscopic capsulolabral reconstruction between 2004 and 2016. Read More

Background: Abscess formation in the subscapularis muscle is a rare clinical condition. Few reports are available regarding the treatment methods and surgical approaches for subscapularis intramuscular abscesses. Here, we describe a case of subscapularis intramuscular abscess that was treated successfully via surgical drainage using a new approach, the "dorsal subscapularis approach". Read More

School of Physical Therapy and Rehabilitation, Pamukkale University, Denizli, Turkey.

Background: Strong core stabilization not only minimizes the load on the vertebral column, but also improves strength and endurance of peripheral joints, and enables the energy transfer to distal segments. Despite the current interest surrounding core stability, none of the studies investigated the effect of core stability on the formation of rotator cuff tear or healing after repair.

Objective: To determine the relationship between core stability and upper extremity functional performance in patients who underwent rotator cuff repair surgery and to compare those with healthy subjects of similar age. Read More

Department of Orthopaedic Surgery, Graduate School of Biomedical & Health Sciences, Hiroshima University, Hiroshima, Japan.

Background: We performed arthroscopic rotator cuff repair (ARCR) combined with miniopen supraspinatus and infraspinatus muscle advancement for massive rotator cuff tears (RCTs) to decrease tension at the repair site with the goal of reduction of the failure rate. We evaluated the clinical outcomes and failure rate after this procedure.

Methods: This study included 47 patients diagnosed with chronic massive RCTs between October 2010 and March 2015. Read More

OBJECTIVE To characterize the MRI and histologic features of the supraspinatus tendon in nonlame dogs. ANIMALS 7 cadavers (14 shoulder joints) of nonlame 2-year-old sexually intact male Beagles. PROCEDURES Multiple MRI fluid-sensitive pulse sequences were obtained for both shoulder joints of each cadaver, and the thickness, volume, and signal intensity of each supraspinatus tendon were assessed.

Background: The suprascapular nerve accounts for 70% of shoulder sensory innervations, and suprascapular nerve block (SSNB) has been shown to be effective in the relief of chronic shoulder pain including rotator cuff tendinitis, subdeltoid impingement syndrome, and adhesive capsulitis. However, this remains inconclusive for patients undergoing surgery. The present meta-analysis aimed to explore the effectiveness of SSNB for relieving acute post-operative shoulder pain. Read More

Background: This study was conducted to verify the effects of adipose-derived stem cells (ADSCs) on tendon healing and reversal of fatty infiltration in a chronic rotator cuff tear model by using the rabbit subscapularis (SSC).

Methods: The SSC insertions in 32 rabbits were cut bilaterally. After 6 weeks, secondary procedures were performed bilaterally, dividing the rabbits into 4 groups of 8 rabbits each as follows: the ADSC+repair group, saline+repair group, ADSC-only group, and saline-only group. Read More

The reverse shoulder arthroplasty indications are cuff tears arthropaty, revision of anatomic prosthesis and traumatology. The reverse shoulder arthroplasty doesn't need a rotator cuff integrity to be functional. However, complications are not rare (dislocation, descellement, infection. Read More

Pain in the postoperative shoulder is difficult for all individuals involved. The patient has already undergone a surgical procedure and is presenting now with pain possibly relating to a complication of the procedure or reinjury. In addition, the patient typically has undergone a series of maneuvers, from physical therapy to cortisone injection, without relief of the symptoms. Read More

Seventy-one cases of subluxation or dislocation of the long head of the biceps tendon (LHB) were retrospectively evaluated. Subluxation was observed in 25 (35%) cases combined with partial tearing of the subscapularis tendon and in 70% with tears of the supraspinatus tendon. Dislocation was defined as a permanent loss of contact between the tendon and the intertubercular groove; it was observed in 46 (65%) cases. Read More

In total shoulder replacement the result is highly dependent upon the integrity or reconstructability of the muscles, tendons, and capsule, as well as the experience of the surgeon. Stability and function of an unconstrained implant are a result of the interrelationship of critical factors such as humeral length, humeral and glenoid version, appropriate abductor tension, rotator cuff integrity, and capsular reconstruction. If these factors are not present and preserved, they must be reconstructed. Read More
