Duchscherer has successful procedure

A's right-hander can resume throwing in a few days

PHOENIX -- An A's spokesperson on Tuesday confirmed that Justin Duchscherer's scheduled nerve ablation procedure "went well."

The A's right-hander will rejoin teammates at Phoenix Municipal Stadium on Wednesday but is not expected to begin throwing again for a few days.

Duchscherer, 31, underwent the procedure at the Arizona Center for Pain Relief to calm an irritated sacroiliac joint, which connects the base of the spine to the pelvic bone. He was bothered by the same problem last year while rehabbing from minor elbow surgery and received three cortisone shots for the joint, which stopped responding to the treatment.

Thus, the ablation process, as described by Duchscherer on Sunday, burns off the nerve ends of the SI joint using radio waves to produce heat that destroy the nerve and relieve the pain. The burnt nerve eventually grows back, so it's possible he will have to undergo the operation again if the discomfort resurfaces.

The two-time All-Star, though slightly nervous about the procedure, insisted that it's a minor setback and recovery time usually varies from one day to one week.
