Having settled his/her claim against Employer/Insurer, Patrick Benoist, Employee herein, seeks an award under Section 287.220.1 Mo. Rev. Stat. (2000) for permanent total disability compensation against the Second Injury Fund. Employee claims that he is permanently and totally disabled as a result of the combination of the disabilities due to the occupational diseases affecting his upper extremities which developed around July 1, 2005 and the preexisting disabilities in his low back and both knees. The Second Injury Fund contends that Claimant was not rendered permanently and totally disabled by the combination of Claimant's primary injuries with his preexisting disabilities, and that if he was rendered permanently and totally disabled, it was due to the occupational diseases affecting his upper extremities alone and without regard to his preexisting disabilities.
Section 287.220.1 Mo. Rev. Stat. (2000) provides that where previous partial disability or disabilities, whether from a compensable injury or otherwise, and the last injury combine to result in total and permanent disability, the employer at the time of the last injury is liable only for the disability which results from the last injury considered by itself and the Second Injury Fund shall pay the remainder of the compensation that would be due for permanent total disability under Section 287.200. Grant v. Neal, 381 S.W.2d 838, 840 (Mo. 1964); Searcy v. McDonnell Douglas Aircraft Co., 894 S.W.2d 173, 177-78 (Mo. App. 1995); Reiner v. Treasurer of State of Mo., 837 S.W.2d 363, 366 (Mo. App. 1992); Brown v. Treasurer of Missouri, 795 S.W.2d 479, 482 (Mo. App. 1990). The employee must prove that a prior permanent partial disability, whether from a compensable injury or not, combined with the subsequent compensable injury to result in total and permanent disability.
Obviously, where the disability caused by the primary injury is total disability, there can be no liability for the Second Injury Fund. For the Second Injury to be liable for permanent total

[^0]: 1 At the beginning of the hearing, the parties agreed that there was a dispute as to whether the left elbow cubital tunnel syndrome was a compensable occupational disease. In their proposed awards, both parties agreed that Claimant's left cubital tunnel syndrome was a compensable occupational disease and part of the primary injury. (See Page 4 of Claimant's Proposed Award and Page 7 of the Second Injury Fund's Proposed Award.) Given the agreement of the parties, it will not be necessary to make findings as to whether the left cubital tunnel syndrome was part of the primary injury.
disability compensation, the total disability must result from the combination of the preexisting disabilities and the disability caused by the primary disability. If total disability is caused by the primary injury alone, there can no combination. The employee is not entitled to permanent total disability compensation from both the Second Injury Fund and the employer. Hughey v. Chrysler Corp., 34 S.W.3d 845, 847 (Mo. App. 2000); Vaught v. Vaughts Inc., 938 S.W.2d 931, 939 (Mo. App. 1997); Roller v. Treasurer of State of Mo., 935 S.W.2d 739, 740 (Mo. App. 1996).
Where the last injury alone causes the employee to become permanently and totally disabled, then the employer is liable for permanent disability compensation under Section 287.200. See Mathia v. Contract Freighters, Inc., 929 S.W.2d 271, 276 (Mo. App. 1996); Feldman v. Sterling Properties, 910 S.W.2d 808, 810 (Mo. App. 1995); Moorehead v. Lismark Distributing Co., 884 S.W.2d 416, 419 (Mo. App. 1994); Kern v. General Installation, 740 S.W.2d 691, 692 (Mo. App. 1987); see also Terrell v. Board of Education, City of St. Louis, 871 S.W.2d 20 (Mo. App. 1993); Reves v. Kindell's Mercantile Co., Inc., 793 S.W.2d 917 (Mo. App. 1990); Roby v. Tarlton Corp., 728 S.W.2d 586, 589 (Mo. App. 1987); Weinbauer v. Gray Eagle Distributors, 661 S.W.2d 652 (Mo. App. 1983); Fogelsong v. Banquet Foods Corporation, 526 S.W.2d 886 (Mo. App. 1975); Mashburn v. Chevrolet Kansas City Div., G.M. Corp., 397 S.W.2d 23 (Mo. App. 1965); Garrison v. Campbell "66" Express, 297 S.W.2d 22 (Mo. App. 1956).
On the other hand, where permanent and total disability results only from the combination of the disability from the primary injury with preexisting disabilities and with unrelated post-primary injury progression of preexisting disabilities, the Second Injury Fund is not liable for permanent and total disability. The Second Injury Fund is not liable for any postaccident worsening of an employee's preexisting disabilities which are not caused or aggravated by the last work-related injury or for any conditions which arise after the last work-related injury. Lammert v. Vess Beverages, Inc., 968 S.W.2d 720, 725 (Mo. App. 1998); Garcia v. St. Louis County, supra; Frazier v. Treasurer of Missouri, 869 S.W.2d 152 (Mo. App. 1994); Lawrence v. Joplin R-VIII School Dist., 834 S.W.2d 789 (Mo. App. 1992); see also Wilhite v. Hurd, 411 S.W.2d 72 (Mo. 1967).
The first determination to be made is the extent compensation liability of the employer for the last injury, considered alone. Hughey v. Chrysler Corp., 34 S.W.3d 845, 847 (Mo. App. 2000); Vaught v. Vaughts Inc., 938 S.W.2d 931, 939 (Mo. App. 1997); Roller v. Treasurer of State of Mo., 935 S.W.2d 739, 740 (Mo. App. 1996). After that has been determined, then the extent of preexisting disabilities is to be determined. Lastly, the fact finder is determine whether the preexisting disabilities combine with disabilities from the primary injury to create permanent total disability. Where the combination of those disabilities causes permanent total disability, th
