New method restores grip function more quickly to patients with tetraplegia

10.04.2013
A new method in which a number of operations are performed simultaneously can provide people with tetraplegia with a better grip function and the ability to open their hand. This method also shortens the patient’s rehabilitation period by at least three months, reveals a doctoral thesis from the Sahlgrenska Academy, University of Gothenburg, Sweden.
If the neck is broken and there is a cervical spinal cord injury, muscles in the arm and hand are paralysed. But in many cases some muscle functions remain, which makes it possible to transfer muscles and tendons and thereby restore a tetraplegic person’s grip function.

About 50 or so such hand operations are performed every year at the Sahlgrenska University Hospital, and patients come from both Sweden and Europe. There have been major advances in surgical techniques in recent years. For example, the method of connecting tendons is now so strong and can withstand such a heavy strain that the patient can start to exercise his or her grasp just one day after the operation.

A dissertation at the Sahlgrenska Academy, University of Gothenburg, describes a new method in which several operations can be combined and performed simultaneously in order to create both a grasp and release function of the hand in people with tetraplegia following a cervical spinal cord injury.

Compared with previously, when at least two operations were required to achieve the same functions, according to the thesis the simultaneous interventions can shorten the treatment period at the ward by an average of ten days for each hand, saving the patient at least three months of rehabilitation.

“The operation not only gives the patient a reconstruction of the pinch and grip function, but also the ability to open the hand,” says Carina Reinholdt, Senior Consultant in hand surgery and Doctor of Medicine at the Sahlgrenska Academy, University of Gothenburg.

“The fact that the patient can start exercising immediately also reduces the risk of adhesion formations and scarring around the transferred tendons. The post-operative results are also better: the grip strength is twice as strong and the ability to open the hand is better than in traditional, separate operations.”

For the patient, a reconstructed grasp function means greater independence. With a functional grasp, a paralysed person can feed himself/herself, take care of his/her own hygiene, use a computer or mobile phone more easily, and hold and greet people.

“In our everyday lives we encounter countless instances where you need a good grip and the ability to open your hand. For many patients, this operation has meant that they’ve been able to return to work on a part-time basis,” says Carina Reinholdt.

Im Focus: Megakaryocytes act as „bouncers“ restraining cell migration in the bone marrow

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

Im Focus: Artificial neural network resolves puzzles from condensed matter physics: Which is the perfect quantum theory?

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...

Im Focus: Modelling leads to the optimum size for platinum fuel cell catalysts: Activity of fuel cell catalysts doubled

An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.

Fuel cells may well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could be produced for example using surplus...
