(1) The plaintiff is aged fifty, and was employed as a lounge attendant at the Qantas Club by the first defendant from November 1997.
(2) On 26 September 1999, in the course of her employment the plaintiff was lifting a heavy tray of glasses when she suffered a disc prolapse at L5-S1. She experienced pain in the back, shoulder, and referred pain into the left leg. She was treated by Dr Irani, and ultimately returned to work on 6 October 1999.
(3) She continued in her employment with the first defendant at the Qantas Club from the period of early October until 6 June 2000. During that period the plaintiff received no medical treatment for her back, nor did she take medication, although she did continue to experience symptoms of back pain from time to time.
(4) In the course of her employment for the first defendant during that period, there was no specific incident at work which resulted in further injury to the plaintiff's low back.
(5) On 6 June 2000, at approximately 5 am when she was getting out of bed at her home, the plaintiff suffered an aggravation of the injury to her low back on 26 September 1999 and this aggravation involved symptoms of low back pain and referred pain into her left leg.
(6) The plaintiff consulted a general practitioner on 6 June 2000, but apart from two further days at work she has not worked again since 13 June 2000.
(7) An MRI and CT scan of the plaintiff's lumbar spine carried out on 4 July 2000 and 22 June 2000 respectively revealed a large and left-sided L5-S1 lumbar disc prolapse with displacement and probable compression of the left S1 nerve root.
(8) Operative treatment was finally carried out on 8 May 2003 by Mr Brian Barrett, involving decompression of L5-S1 and an inter-transverse type fusion. The operation was a success, and fitted the plaintiff for return to lighter forms of work.
(9) I am not satisfied that the plaintiff suffered compensable injury on or after 20 October 1999 with the first defendant.
(10) Any pain and loss of function the plaintiff has experienced in respect of her low back on or after 20 October 1999, is a consequence of the compensable injury the plaintiff suffered on 26 September 1999 which was aggravated in non-compensable circumstances on 6 June 2000.
