C.A. 2nd;
B279412

The Second Appellate District annulled a decision of the Workers' Compensation Appeals Board and remanded. The court held that a workers' compensation claimant was entitled to an unapportioned award for injuries sustained while receiving medical treatment for an industrial injury.

Maureen Hikida developed carpal tunnel syndrome while working for Costco Wholesale Corporation. She had surgery, which failed, triggering a condition that rendered her permanently and totally disabled. Deeming the surgery an intervening cause, the workers' compensation judge found Hikida's disability was only 90 percent due to industrial factors and ten percent due to nonindustrial factors.
