Predictability and functional impact of lateral acromioplasty using preoperative 2D planning on the correction of the critical shoulder angle (CSA) in patients with rotator cuff repair.

Background: Rotator cuff tears are highly prevalent, and their association with critical shoulder angle (CSA) has been reported. There is controversy regarding whether the morphology of the acromion influences its incidence, as well as whether acromioplasty would impact the results of a rotator cuff repair. Lateral acromioplasty does not play a decompressive role; rather, it aims to correct the deltoid vector.

Complications of Locked Plating for Proximal Humeral Fractures in Active Patients in a Level One Trauma Center.

Background: The incidence of complications associated with locked plating of proximal humerus fractures (PHF) has been reported in up to 40% of surgeries. This study aimed to analyze the incidence and risk factors of complications and re-intervention associated with locked plating of PHF in a an young active working population.

Methods: This retrospective cohort study included patients indicated for locked plating of displaced PHF at a dedicated workers' accident trauma center.

Nanoscopic Distal Biceps Repair With Cortical Button and Interference Screw.

Distal biceps pathology can be addressed using different techniques, each with its advantages and disadvantages. The current trend is to move toward minimally invasive procedures based on feasibility and known clinical benefits. Endoscopy for distal biceps pathology is a safe procedure.

Good functional results with open reduction and internal fixation for locked posterior shoulder fracture-dislocation: a case series.

Background: There is no standardized therapeutic strategy for locked posterior shoulder fracture-dislocation (PSFD), and no consensus exists on the analysis of preoperative factors. This retrospective study aimed to evaluate functional results and complications in a series of PSFD cases managed with open surgical treatment.

Methods: Patients diagnosed with locked PSFD who underwent open surgical treatment with reduction and osteosynthesis between April 2016 and March 2020 were included.

Similar optimal distalization and lateralization angles can be achieved with different reverse shoulder arthroplasty implant designs.

Background: Optimal postoperative distalization (DSA) and lateralization (LSA) shoulder angles have been described as radiological measurements correlated with function after reverse shoulder arthroplasty (RSA). The proposed optimal values are DSA between 40° and 65° and LSA between 75° and 95°; however, whether these values can be reached with different implant designs is unclear.

Aim: To determine which RSA implant could achieve higher rates of optimal DSA and LSA, to determine any association between each implant and optimal DSA and LSA, and to assess the correlation of the preoperative critical shoulder angle (CSA) and acromial index (AI) with the DSA and LSA.
