Patients Should Wait at Least Six Weeks, Optimally 12 Weeks, before Driving after Total Shoulder Replacement Surgery

13.03.2014

Significant reduction in simulator collisions at 12 weeks, compared to pre-surgery and two weeks post-surgery rates

More than 53,000 Americans have total shoulder joint replacement (SJR) surgery each year, and yet the effects of this surgery on a patient’s ability to safely drive a vehicle, and the appropriate recovery time before patients should return to driving, have yet to be determined.

In a new study, “Driving Performance after Total Shoulder Arthroplasty,”  the driving skills of 28 shoulder replacement patients, with a mean age of 65 ±10 years, were tested at four distinct time points before, during and after surgery using a driving simulator.

The first test was conducted before surgery; a second test, 14 days following surgery; and third and fourth tests at six and 12 weeks post-surgery, respectively. The number of total simulator collisions, off-road collisions, on-road collisions, center-line crosses and off-road excursions were recorded at each trial.

Pain Visual Analog Scale (VAS) and Shoulder Pain and Disability Index (SPADI) scores also were documented, in addition to annual driving mileage and hours slept the previous night.  In 28 patients, the mean number of collisions decreased from 6.2 during the first test (pre-surgery) to 5.9 at the second test (two weeks after surgery); and from 5.2 during the third test to 4.2 by the fourth and final test.

There was a statistically significant difference in the mean number of collisions between the first and fourth test.  Also, patients who drove less than 1,800 miles per year incurred a greater number of collisions at the first and fourth tests, compared to patients who drove more than 8,700 miles per year. 

“At risk driving behavior,” quantified as the number of center-line crosses, decreased from 20.6 during the first test to 14.8 by the fourth test.  According to the study authors, patients showed improved driving performance at 12 weeks, with a significant decrease in the number of collisions in the simulated driving course compared to the tests conducted preoperatively and two weeks after surgery.

The study authors recommend that patients wait at least six weeks, and optimally 12 weeks, to resume driving following shoulder replacement surgery. Lead author disclosure.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Studying fundamental particles in materials

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
