The use of staples to close wounds following orthopedic surgery – especially hip surgery – is associated with a significantly greater risk of wound infection than traditional suturing, according to orthopedic researchers from Norwich, England. Six clinical trials Toby O. Smith, MSc, BSc (Hons), MCSP, and colleagues analyzed the results of six trials that compared staples and sutures used for wound closure following… Read the rest

Refine Intraoperative x-ray technique to routinely achieve an Acetabular inclination angle of less than 50 degrees by Dr. Gross 2012

Refined Intraoperative X-ray Technique to Routinely Achieve an Acetabular Inclination Angle < 50ºThomas P. Gross, MD (d), Fei Liu, PhD (d) Midlands Orthopaedics, P.A. Columbia, SC.6/5/2012INTRODUCTION

A steep acetabular inclination angle is the primary cause of adverse wear related failure with well-designed metal-on-metal bearing hip resurfacing arthroplasties (HRA). One recent study demonstrated that positioning acetabular components of stemmed total hip arthroplasties (THA) within the “Lewinnek safe zone” is difficult; only 62% had AIA
