Cemented metal-on-metal total hip replacement with 28-mm head: prospective, long-term, clinical, radiological and metal ions data.

Purpose: The aim of this study was to evaluate the long-term clinical, radiological and metal ion blood concentration results following 28-mm metal-on-metal cemented total hip replacement using Metasul(®) acetabular component and polished, cannulated Allopro CF-30 (Sulzer-Medica, subsequently Centerpulse-Zimmer, Winterthur, Switzerland) femoral component.

Methods: Prospective follow-up of patients operated between 1997 and 2000 at a district general hospital.

Results: Seventy-nine patients (89 implants) with female predominance and median age of 66 years (IQR 45-87 years) were prospectively followed up for mean 13 years (11-14 years).

Three-column classification and Schatzker classification: a three- and two-dimensional computed tomography characterisation and analysis of tibial plateau fractures.

Objective: The aim of the study was to evaluate inter-observer reliability and intra-observer reproducibility between the three-column classification and Schatzker classification systems using 2D and 3D CT models.

Materials And Methods: Fifty-two consecutive patients with tibial plateau fractures were evaluated by five orthopaedic surgeons. All patients were classified into Schatzker and three-column classification systems using x-rays and 2D and 3D CT images.
