A jury awarded $28.2 million to a woman who said treatment delays by Kaiser Permanente doctors forced the amputation of her leg. A Los Angeles County Superior Court jury on Wednesday found that the medical group was negligent in its treatment of Anna Rahm. Rahm, 23, of Chatsworth, complained of back pain when she was 16. Her lawsuit contended that two Kaiser physicians refused to order an MRI for four months. When the test finally was performed, it showed that Rahm had an aggressive cancer of the pelvis. A portion of Rahm’s spine, half her pelvis and her right leg were removed.
