Humeral bone loss is commonly encountered during revision shoulder arthroplasty and anticipating humeral bone defects can help the revision surgeon make appropriate plans to achieve adequate fixation and stability. No validated classification system exists to characterize humeral bone loss in the setting of revision shoulder arthroplasty.
Patients who received interscalene brachial plexus block plus soft tissue infiltration with Exparel when undergoing primary shoulder arthroplasty used significantly more narcotics postoperatively and had no significant reduction in pain scores in the early postoperative period compared with patients who received interscalene brachial plexus block alone, according to results published in The Journal of Bone and Joint Surgery.

Although healing rates and outcomes of arthroscopic single-row rotator cuff repairs have been compared with double-row repairs, none have utilized triple-loaded anchors.
To compare healing and function after single-row repairs with triple-loaded anchors versus double-row repairs with a suture-bridge technique.
Trauma can fracture the scapular neck. Typically, a single plate along the lateral scapula border affixes the glenoid fragment to the scapula. This method is limited by difficulty in screw placement, frequent excessive soft tissue dissection, and risk for neurovascular injury. Substituting 2 smaller plates bridging the scapular neck mitigates these limitations, but no comparative mechanical data between techniques exists. Therefore, we compared the mechanical properties of two constructs securing a simulated scapular neck fracture.

Sore shoulder remedies: This common joint problem can affect anyone. Shoulder pain may involve the cartilage, ligaments, muscles, nerves, or tendons. It can also include the shoulder blade, neck, arm, and hand.

Reverse total shoulder arthroplasty (rTSA) reliably reduces pain and improves function in patients with rotator cuff arthropathy, failed shoulder arthroplasty, proximal humeral fractures, and irreparable rotator cuff tears.4 Nevertheless, postoperative complications are common, and reported rates range between 7% and 21%, with instability being among the most common.7,11 Instability rates after rTSA have ranged between 0% and 16% with risk factors including male sex, high body mass index, rTSA as revision for a prior failed arthroplasty, failure to adequately tension the soft tissues, and component impingement.
Instability is the most common complication after reverse total shoulder arthroplasty (rTSA). In the native glenohumeral joint, in addition to full dislocations, more subtle forms of instability exist. However, the incidence of more subtle forms of instability, the factors associated with instability, and the effect of instability on validated outcome scores after rTSA remain poorly understood.
