Does Computer-assisted Surgery Improve Lag Screw Placement During Cephalomedullary Nailing of Intertrochanteric Hip Fractures?

Clin Orthop Relat Res 2020 Jun 1. Epub 2020 Jun 1.

M. Kuhl, St. Cloud Orthopedics, Sartell, MN, USA C. Beimel, Stryker Trauma GmbH, Kiel, Germany.

Background: Computer-assisted surgery (CAS) techniques have been shown to improve implant placement and reduce the radiation time during cephalomedullary nailing in cadaveric and pilot clinical studies of intertrochanteric hip fractures. However, clinical comparisons of CAS and conventional techniques are lacking. It is unclear whether CAS offers clear advantages in terms of radiation time, operative time, and accuracy of lag-screw placement in patients undergoing surgery for intertrochanteric hip fractures and whether any potential difference in accuracy is associated with a change in the risk of lag-screw cut-out postoperatively.

Indocyanine Green-Coated Polycaprolactone Micelles for Fluorescence Imaging of Tumors.

ACS Appl Bio Mater 2020 Apr 8;3(4):2344-2349. Epub 2020 Mar 8.

Department of Bioengineering, School of Engineering and Applied Sciences, University of Pennsylvania, Philadelphia, Pennsylvania 19104, United States.

Recently, near-infrared (NIR) fluorescent dyes such as indocyanine green (ICG) have received tremendous interest as contrast agents for use in fluorescence-guided, intraoperative cancer resection surgery. However, despite showing great promise, ICG has many shortcomings such as rapid clearance and poor tumor accumulation. To improve the selective accumulation of ICG within tumors, numerous groups have formulated ICG into nanoparticles, but these approaches can suffer from rapid leakage of ICG, use of materials that exhibit poor or incomplete excretion, or complex chemistries that are not easily amenable to scale up for clinical use.

A systematic review of MAKO-assisted Unicompartmental Knee Arthroplasty.

Int J Med Robot 2020 May 23:e2124. Epub 2020 May 23.

Department of Orthopeadics, the Second Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, China.

Unicompartmental knee arthroplasty (UKA) which has many potential advantages compared with total knee arthroplasty (TKA) was widely used across the world in recent years. The introduction of the robot systems greatly makes up for the defects of the conventional UKA surgery such as higher complication rates and revision rates. MAKO system, a new image-guided robot system relies on a preoperative computed tomography (CT) scan to assist in preoperative mapping and planning, offers an opportunity to improve the outcome of UKA surgeries.
