Functional outcome and CEUS-assessed deltoid muscle vitality after fracture-specific versus standard prosthetic design in reverse shoulder arthroplasty for trauma.

J Orthop Res 2022 Jun 3. Epub 2022 Jun 3.

Center for Orthopaedics, Trauma Surgery and Spinal Cord Injury, Ultrasound Center, Heidelberg University Hospital, Heidelberg, Germany.

Functional outcome after reverse-shoulder-arthroplasty (RSA) in proximal humerus fractures (PHF) depends on deltoid muscle integrity and successful reattachment of the tuberosities for best possible recovery of rotator-cuff function. In this monocentric, prospective, randomized, controlled trial we investigated whether a reverse-fracture-prosthesis (RFP) with a metaphyseal fenestrated stem achieved superior shoulder and muscle function compared to a common reverse-prosthesis (RP) design for patients with PHF. Our hypothesis was that patients with RFP may achieve a superior healing rate of the greater tuberosity (GT) compared to patients receiving RP, which translates to significantly higher clinical outcome and functional scores as well as differences in deltoid muscle microperfusion.

Editorial Commentary: Increased Graft Thickness With Superior Capsular Reconstruction Results in Improved Acromiohumeral Distance, but Increased Graft Tear Rate and Lateral Acromial Erosion.

Brian R Waterman

Arthroscopy 2022 Jun;38(6):1793-1795

For the treatment of irreparable posterosuperior rotator cuff tears of the supraspinatus and infraspinatus, superior capsular reconstruction (SCR) has continued to supplant other less successful and/or reproducible techniques, including partial rotator cuff repair and latissimus tendon transfer. After its initial description utilizing a folded fascia lata autograft with a thickness of up to 8 mm, many in North America adapted their surgical technique to use commercially available human dermal allograft to mitigate donor site morbidity. Early series have revealed the importance of graft thickness in predicting risk of radiographic or clinical failure. Read More
