The effect of dynamic external rotation comparing 2 footprint-restoring rotator cuff repair techniques.

Background: Allowing for humeral external rotation while loading rotator cuff repairs has been shown to affect tendon biomechanics when compared with testing with the humerus fixed. Adding dynamic external rotation to a tendon-loading model using footprint-restoring repairs may improve our understanding of rotator cuff repair response to a common postoperative motion.

Hypothesis: A tendon suture-bridging repair will demonstrate better load sharing compared to a double-row repair, and there will be a differential gap formation between the anterior and posterior tendon regions.

Dual direct lateral portals for treatment of osteochondritis dissecans of the capitellum: an anatomic study.

Purpose: The purpose of this study was to quantify the distance of dual direct lateral (posterolateral radiocapitellar) arthroscopic portals to the lateral ligamentous structures and to report the percentage of capitellum accessible through these portals.

Methods: Arthroscopy was performed on 10 fresh-frozen cadaveric elbows via a standard 6-portal approach. The portals included dual direct lateral portals created in the posterolateral soft spot.

Hip fracture outcomes in patients with Parkinson's disease.

In a prospective, consecutive study conducted at a university teaching hospital, we evaluated the effects of Parkinson's disease (PD) on hip fracture outcomes. We followed 920 community-dwelling patients, aged 65 or older, who sustained a hip fracture that was operatively treated between July 1, 1987, and June 30, 1998. Presence or absence of PD had no bearing on type of surgery performed.
