Repsol Honda’s Dani Pedrosa has undergone surgery for the arm pump that has plagued him for more than a year in an operation that surgeons described as complicated and agressive.

The surgery took just over two hours with Dr Villamor confident of its success. During today’s surgery, Dr Villamor completely removed the layer of fascia –  the casing around the muscle that gives it form and shape – which is causing Pedrosa difficulty.

“The surgery was complicated and aggressive using a microsurgery technique and microscopic lens. It lasted two hours, and was done under a local anaesthetic. We examined the muscle fascia, which were hypertrophied and had to be opened up and released,” said Dr Villamor.

“The muscle fascia has been dissected and removed from the forearm. This increased volume engorged the muscle within the inelastic fascia resulting in increased pressure within the compartment, and causing a painful condition of oxygen deprivation – thus causing intense pain in the forearm which collapsed after exercising during riding. We will now monitor Dani over the next few weeks to measure the success of this surgery.”
