Innovations in orthopaedic technology and infrastructure growth often require significant funding. Although an increasing trend has been observed for third-party investments into medical startups and physician practices, no study has examined the role of this funding in orthopaedics, including the influence of venture capital (VC). Therefore, this study analyzed trends in VC investments related to the field of orthopaedic surgery, as well as the characteristics of companies receiving said investments. Venture capital investments into orthopaedic-related businesses were reviewed from 2000–2019 using Capital IQ, a proprietary market intelligence platform documenting financial transactions. The dataset was initially filtered to include healthcare-related venture capital transactions pertaining to the field of orthopaedic surgery. The final list of VC investments and their corresponding businesses were categorized by transaction year, amount (in USD), and orthopaedic subspecialty. The number and sum of VC investments was calculated both annually and cumulatively across the entire study period. Linear regression was used for trend analysis within two distinct, decade-long timeframes (2000–2009 and 2010–2019) and one-way analysis of variance was used to assess differences across orthopaedic subspecialties.Introduction
Methods
Proper positioning of the acetabular component is critical for prevention of dislocation and excessive wear for total hip arthroplasty (THA) and hip resurfacing. Consideration of preoperative pelvic tilt (PT) may aid in acetabular component placement. The purpose of this study was to investigate how PT changes after hip resurfacing, via pre and post-operative radiographic analysis of anterior pelvic plane (APP), and whether radiographic analysis of the APP is a reproducible method for evaluating PT in resurfaced hips. A consecutive group of 228 patients from a single surgeon who had hip resurfacing were evaluated. We obtained x-rays from an institutional database for these patients who had their surgeries between January 1st, 2014 to December 31st, 2016. Pelvic tilt (PT) was measured by two observers before and after resurfacing utilizing a standardized radiographic technique. Correlation coefficients were calculated for PT measurements between observers, and pre- and post-surgery.Background
