Introduction

Sacro-coccygeal chordomas pose a difficult diagnostic and therapeutic problem due to late presentation, large size, soft-tisue extension, difficulties in obtaining adequate resection margins, higher local recurrence rate and uncertain effectiveness of adjuvant treatment. We present a series of 21 patients of sacral chordomas obtained from Scottish Bone Tumour Registry to analyse predictors of local control and survival.

Patients and methods

The clinical and morphologic features, type of treatment and follow-up of 21 consecutive patients with sacral chordoma were retrospectively reviewed and analysed.

Purpose

To examine measurement properties of four disability outcomes in patients with advanced osteoarthritis of the glenohumeral joint.

Methods

This was a prospective longitudinal study of patients with advanced osteoarthritis of the glenohumeral joint who underwent a Total Shoulder Arthroplasty (TSA) and were followed for 6 months. Four measures [Western Ontario Osteoarthritis Shoulder (WOOS) Index, the American Shoulder and Elbow Surgeons (ASES) assessment, Constant-Murley score (CMS), and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH)] were completed 2-3 weeks before surgery and at 6 months after surgery.

Introduction

The articulating surfaces of a new metal-on-metal (MoM) hip prosthesis system were modified with the ceramic Titanium-Niobium-Nitride (TiNbN) by Physical Vapor Deposition (PVD). The purpose of the study was to investigate whether the elevation of the ion levels of chromium and cobalt, normally seen in the blood of patients after MoM hip arthroplasty, can be prevented by ceramic engineering of the articulating metal surfaces.

Materials and methods

the ACCIS components (manufactured by Implantcast GmbH, Buxtehude, Germany from casted hi-carbon Co-Cr-Mo alloy) are heat treated, polished and micro-surface finished. Then TiNbN ceramic is integrated into the metal surfaces by PVD.

200 ACCIS resurfacing hip prostheses were implanted in three centres: Morriston Hospital, Swansea and Neville Hall Hospital, Abergavenny in the UK and Arthro Clinic, Hamburg, Germany. Blood samples of 60 randomly selected patients were analysed before surgery and at intervals of 3, 6, 12 and 24 months after surgery. Independent trace metal measurements were performed at the Universitätsklinikum Carl Gustav Carus Dresden, Germany.
