Matched Cohort Study Comparing Arthroscopic-Assisted Versus Full-Arthroscopic Latissimus Dorsi Tendon Transfer for Irreparable Massive Rotator Cuff Tears.

Background: Latissimus dorsi tendon transfer (LDTT) is increasingly performed with arthroscopic assistance, requiring an open axillary incision, which could increase risks of infection, hematoma, and lymphoedema. Technological advancements now enable LDTT to be fully arthroscopic, but its benefits and safety have not yet been confirmed.

Purpose: To compare the clinical outcomes and complication rates of arthroscopic-assisted versus full-arthroscopic LDTT for irreparable posterosuperior massive rotator cuff tears in shoulders with no surgical antecedents.

Treatment of bone cysts by percutaneous injection of demineralized bone matrix mixed with bone marrow.

Bone cysts whether aneurysmal or simple, are known for their tendency to recur. To replace the classical aggressive surgeries, minimally invasive techniques were developed giving differing results based on variable radiographic criteria. No unique percutaneous treatment has proven effective on both types of cysts.
