The Effect of Instrumentation on Suture Tensile Strength and Knot Pullout Strength of Common Suture Materials.

Objective: To determine the effect of instrumentation of suture material on knot security and tensile strength.

Study Design: In all, 5 types of suture material were used; 10 knots were tied without any instrumentation and 10 knots were tied with a hemostat holding tension on the first throw while the second throw was made for each suture type. Each group was tested to failure with the maximum load and mode of failure recorded.

Outcomes of biceps tenodesis in an active duty population.

Pathology affecting the long head of the biceps tendon and its insertion is a frequent cause of shoulder pain in the active duty military population. The purpose of this investigation was to evaluate functional outcomes of subpectoral biceps tenodesis in an active duty population. A retrospective case series of 22 service members who underwent biceps tenodesis was performed and Shoulder Pain and Disability Indexes (SPADI) and Disabilities of the Arm, Shoulder and Hand (DASH) scores were obtained preoperatively and at 6 months.

A criterion based sling weaning progression (sweap) and outcomes following shoulder arthroscopic surgery in an active duty military population.

Introduction: Little objective evidence is available to guide rehabilitation protocols in regard to the sling weaning process following arthroscopy surgery of the shoulder. The purpose of this study was to establish an objective, criterion based protocol for accelerated sling weaning following shoulder arthroscopy.

Methods: 82 active duty service members (ADSM) underwent elective shoulder arthroscopic surgery by three orthopaedic staff surgeons.

The safety of spinal pedicle screws in children ages 1 to 12.

Background Context: Pedicle screws have shown to be a safe and effective method of spinal fixation, offering superior multiplanar correction compared with hooks or sublaminar wires in selected situations. Though only food and drug administration (FDA) approved in the adolescent population, they are commonly used in an off-label manner in the preadolescent population.

Purpose: To determine if the complication rate of the off-label use of pedicle screws for spinal fixation in the preadolescent 0- to 12-year-old population is comparable with the complication rate in the FDA-approved 13- to 18-year-old population.
