A miner that in 2009 was diagnosed with ""STRAIN LUMBO SACRAL, HNP L4-5, L5-S1, RADICULOPATIA L5-S1 BILATERAL"" did not report to duty on March 4, 2010. The miner was referred to El Fondo del Seguro del Estado to receive medical treatment. Allegedly the vibration of the 966C Front Loader caused by the dumping of the bucket caused the injury or aggravated his previous condition.
