Foreseeing the danger in the beach chair position: Are standard measurement methods reliable?

Purpose: The aim of this study is to show whether peripheral perfusion monitoring methods reflect central perfusion during shoulder arthroscopy at beach chair position. We hypothesized that mean arterial pressure (MAP), central heart rate (CHR) and peripheral oxygenation (SaO2) measurements individually will not parallel cerebral oximetry measurements by near-infrared spectroscopy (NIRS).

Methods: Between 2011 and 2012, 53 patients who had arthroscopic rotator cuff repair surgery in the beach chair position were enrolled prospectively.

Technique of Kirschner wire reduction and fixation of displaced two-part valgus angulated proximal humerus fractures at the surgical neck.

This article describes the technique of closed reduction with percutaneous fixation using Kirschner wires in helping the reduction of two-part valgus angulated and displaced proximal humerus fractures at the surgical neck. Traditional open reduction may lead to more accurate anatomic reduction; however, extensive tissue dissection increases the risk of avascular necrosis. Thus, closed reduction of unstable fracture mostly required forceful reduction maneuvers, which can harm the vascular supply and increase hematoma formation.

End-to-end versus augmented repair in the treatment of acute Achilles tendon ruptures.

We prospectively analyzed the functional and clinical results of patients who underwent a single end-to-end suture and an augmented tendon repair with plantaris tendon at middle-term follow-up. From January 2003 to May 2005, 30 consecutive patients were operated on for the treatment of acute Achilles' tendon rupture by means of 2 different methods. No cases required adjunctive procedures to allow for acceptable end-to-end apposition.

Transpedicular decancellation osteotomy in the treatment of posttuberculous kyphosis.

Objective: Although the transpedicular decancellation osteotomy is a salvage technique for reconstruction of complex spinal deformities, it is not a procedure used exclusively for patients with kyphosis occurring as a sequel of treated tuberculosis. In this study, 16 adult patients with kyphosis underwent transpedicular decancellation osteotomy between 1993 and 1999. Pain, kyphosis angle, sagittal balance, and functional and neurologic status were the main parameters used for the clinical and radiologic assessment.
