Published: February 2025

The myotendinous junction is a highly specialized and complex structure between muscle and tendon. In recent years, various procedures have directly targeted the tendon, with corticosteroid, platelet-rich plasma, or biological therapy infiltrations being prominent. However, these interventions are painful, corticosteroids have demonstrated tendon damage, and anesthesia negatively impacts tenocyte proliferation and viability when used with platelet-rich plasma in the same injection site. There is a need to adapt the injection site to improve therapy effectiveness and pain tolerance. This article presents a proposal for an ultrasound-guided anesthetic block procedure in the myotendinous junction.

This review offers a comprehensive discussion of magnetic resonance imaging (MRI) for the assessment of rotator cuff tendon repair and joint-preserving surgical options for patients with irreparable rotator cuff tears. Deciding to proceed with arthroscopic repair of a rotator cuff tendon tear is impacted both by clinical factors and morphological imaging features. Preoperative clinical and imaging features also predict the likelihood of success of a rotator cuff tendon repair and are important to recognize.

Purpose: This study aimed to evaluate the effectiveness of an original mechanical testing setup including the humerus, myotendinous junction and scapula designed to assess the structural properties of rotator cuff attachments in large animals and determine optimal conditions.

Methods: Eight domestic pigs (age, 4-6 months; weight, 30-52 kg) without genetic modifications were euthanized under intubated general anaesthesia control. The scapula-supraspinatus tendon complex with the humerus was excised as a single unit.

Purpose: The main objective was to study the anatomy of the adductor longus by ultrasound and cadaveric dissection, correlate the findings with the different approaches described, and evaluate the feasibility of defining a "safe window" for interventional musculoskeletal procedures.

Methods: The anatomical study was performed on six cadaveric pieces, while ultrasound evaluations were performed on both lower limbs of 26 subjects (n = 52). Ultrasound variables included the number of saphenous veins, the location of the saphenous vein in relation to the proximal myotendinous junction, the number of vessels within or superficial to the adductor longus, and the distance between the dermis and the inferior border of the adductor longus to the anterior branch of the obturator nerve.

Long head of the biceps tendon pathology is a well-described proximal shoulder pain generator. While optimal treatment strategy remains controversial, popular operative management includes biceps tenodesis. However, appropriate restoration of the anatomic length-tension relationship of the biceps with tenodesis remains a challenge.
