Modified Margin Convergence: Over-Under Lacing Suture Technique.

The principle of margin convergence can be applied to rotator cuff repair to enhance the security of fixation by decreasing the mechanical strain at the margins of the tear. We describe a suture technique, over-under lacing, that reproduces the same margin convergence, with equal tissue tension across the entire surface area of the cuff. A consecutive series of patients affected by massive U-shaped rotator cuff tears were treated by this repair technique.

Adequacy of treatment, bone remodeling, and clinical outcome in pediatric supracondylar humeral fractures.

The aim of this study was to evaluate and compare, both clinically and roentgenographically, 62 extension-type supracondylar fractures on the basis of the synthesis method and severity of the fracture, with a mean follow-up of 4 years and 3 months. Range of motion, axial alignment of the elbow, muscle strength, and joint stability were estimated and the Mayo Elbow Performance Index and the Pediatric Orthopaedic Society of North America Pediatric Outcomes Data Collection Instrument questionnaire were used. Furthermore, we took radiographic measurements (Baumann's angle, humero-capitellar angle, and lateral rotational percentage).
