Shoulder surgery in beach chair position causing perioperative stroke: Four cases and a review of the literature.

Perioperative stroke is a rare, but serious complication in shoulder-arthroscopy or arthroplasty. Recent literature suggests the beach chair position, widely used during shoulder surgery, might induce severe perioperative hypotension, and with this cerebral desaturation and ultimately perioperative stroke. In this article we report four cases of perioperative stroke in shoulder surgery.

Early weight bearing versus delayed weight bearing in medial opening wedge high tibial osteotomy: a randomized controlled trial.

Purpose: The need for a period of non-weight bearing after medial opening wedge high tibial osteotomy remains controversial. It is hypothesized that immediate weight bearing after medial opening wedge high tibial osteotomy would have no difference in functional scores at one year compared to delayed weight bearing.

Methods: Fifty patients, median age 54 years (range 40-65), with medial compartment osteoarthritis, underwent a medial opening wedge high tibial osteotomy utilizing a locking plate without bone grafting.

The results of 163 Achilles tendon ruptures treated by a minimally invasive surgical technique and functional aftertreatment.

Background: There is still controversy regarding the optimal surgical technique and post-operative treatment of acute Achilles tendon ruptures. We evaluated a treatment protocol for Achilles tendon ruptures consisting of a minimally invasive Achilles tendon repair combined with early full weight bearing.

Methods: A consecutive group of 163 patients was prospectively followed during a 6 year period (1998-2004) in one university hospital and five teaching hospitals.
