Medical Study – Patients’ Perceptions of Hip Resurfacing Arthroplasty
By Todd P. Murphy, MD; Robert T. Trousdale, MD; Mark W. Pagnano, MD; Tad M. Mabry, MD; Rafael J. Sierra, MD ORTHOPEDICS 2009 Abstract The purpose of this study was to understand patients’ perceptions regarding hip resurfacing arthroplasty relative to conventional total hip arthroplasty (THA)… …Results A total of 139 consecutive patients were given the survey. Fifty-seven patients (41%) were aware of hip resurfacing arthroplasty and completed the survey. Of those who completed the |
Current status of uncemented femoral components in hip resurfacing by Dr. Gross 2010
Midlands Orthpaedics p.a. Thomas P. Gross, M.D. Current status of uncemented femoral components in hip resurfacing. January, 2010 Uncemented femoral components for metal on metal total hip resurfacing have shown excellent results during the initial 3 years that I have been using this new technology. The early results that I have achieved in 0ver 800 cases since March 2007 are equivalent to the early results that I achieved with the same brand cemented femoral |

Hip Resurfacing Femoral Neck Fracture Influenced by Valgus Placement

Journal: Clinical Orthopaedics and Related Research Citation: 465:71-79, December 2007. Authors: Carolyn Anglin, PhD, PEng; Bassam A Masri, MD, FRCSC; Jérôme Tonetti, MD; Antony J Hodgson, PhD, PEng; Nelson V Greidanus, MD, FRCSC Femoral neck fracture is the most common short-term concern after hip resurfacing arthroplasty. Currently, there is little basis to decide between neutral and valgus placement.We loaded 10 notched cadaveric femur pairs to failure; one side was implanted at 0[degrees]
Do Cysts prevent hip resurfacing by Thomas P Gross 2011
Is there added risk in resurfacing a femoral head with cysts? Thomas P Gross and Fei Liu 17 October 2011Abstract Background Femoral head cysts have been identified as a risk factor for early femoral failures after metal-on-metal hip resurfacing arthroplasty (HRA) based on limited scientific data. However, we routinely performed HRA if less than 1/3 of the femoral head appeared destroyed by cysts on the preoperative radiograph. This study was undertaken to analyze whether |

ABSTRACT:
Background:
Adverse wear reaction after metal-on-metal hip resurfacing has been described as a new failure mechanism. Established causes include poor
implant design, small implant size and acetabular malpositioning. The purpose of this study is to establish a safe zone of acetabular inclination angle … 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

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 |

Hip Resurfacing Compared to Total Hip Replacement Functional Outcomes for 2 Years 2012
Surgical Robot Pilot Study in UK
A new surgical robot is making medical undergraduates three
times more accurate during practice hip operations, according to pilot study to be discussed at a conference this week (8 February 2008).
Link News Website Delegates at the British Society for Computer Aided Orthopaedic Surgery Conference will hear that results from a pilot study saw graduates 95 per cent more confident using this robotic technique than when using conventional surgical methods in training. |

Low Volume Surgeons Poor Outcomes Hip Replacement Study
Optimal acetabular cup positioning is attained in less than 50% of cases, study reportsMarch 9, 2010 NEW ORLEANS – High-volume surgeons are more likely than low-volume surgeons to attain optimal cup positioning for total hip arthroplasty, but both groups still attain optimal cup positioning less than half of the time, according to a study presented here. The findings were presented by Bryan Jarrett, BS, at the 56th Annual Meeting of the Orthopaedic Research Society. |
