    (2023) De Marinis Acle Rodrigo Ignacio; Marigi, Erick M.; Atwan, Yousif; Yang, Linjun; Oeding, Jacob F.; Gupta, Puneet; Pareek, Ayoosh; Sanchez-Sotelo, Joaquin; Sperling, John W.
    Artificial intelligence (AI) is a continuously expanding field with the potential to transform a variety of industries -including healthcare- by providing automation, efficiency, precision, accuracy, and decision-making support for simple and complex tasks. Basic knowledge of the key features as well as limitations of AI is paramount to understand current developments in this field and to successfully apply them to shoulder surgery. The purpose of the present review is to provide an overview of artificial intelligence within orthopedics and shoulder surgery exploring current and forthcoming AI applications.

    Lower Trapezius Transfer Improves Clinical Outcomes With a Rate of Complications and Reoperations Comparable to Other Surgical Alternatives in Patients with Functionally Irreparable Rotator Cuff Tears: A Systematic Review
    (2023) Marinis Acle, Rodrigo Ignacio de; Marigi, Erick; Atwan, Yousif; Velásquez García, Ausberto; Morrey, Mark E.; Sánchez Sotelo, Joaquin
    Purpose To analyze the clinical outcomes of lower trapezius transfer (LTT) for patients with functionally irreparable rotator cuff tears (FIRCT) and summarize the available literature regarding complications and reoperations. Methods After registration in the International prospective register of systematic reviews(PROSPERO [CRD42022359277]), a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was performed. Inclusion criteria were English, full-length, peer-reviewed publications with a level of evidence IV or higher reporting on clinical outcomes of LTT for FIRCT. Ovid MEDLINE(R), Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus via Elsevier databases were searched. Clinical data, complications and revisions were systematically recorded. Results Seven studies with 159 patients were identified. The mean age range was 52 – 63 years, 70.4% of the patients included were male, and the mean follow-up time ranged between 14 and 47 months. At final follow-up, LTT lead to improvements in range of motion (ROM), with reported forward elevation (FE) and external rotation (ER) mean gains of 10º – 66º and 11º – 63º, respectively. ER lag was present preoperatively in 78 patients and was reversed after LTT in all shoulders. Patient reported outcomes were improved at final follow-up, including the American Shoulder and Elbow Society score, Shoulder Subjective Value and Visual Analogue Scale. The overall complication rate was 17.6% and the most reported complication was posterior harvest site seroma/hematoma (6.3%). The most common reoperation was conversion to reverse shoulder arthroplasty (5%) with an overall reoperation rate of 7.5%. Conslusions Lower trapezius transfer improves clinical outcomes in patients with irreparable rotator cuff tears with a rate of complications and reoperations comparable to other surgical alternatives in this group of patients. Increases in FF and ER are to be expected, as well as a reversal of ER lag sign when preoperatively present. Level of Evidence Level IV, a systematic review of Level III-IV studies.
