Appellant, Perry Nelson, injured his right shoulder while working for appellee, Basic Materials Corp. In ruling on his claim for workers' compensation benefits, the industrial commissioner awarded permanent partial disability benefits for this injury against Basic Materials and its insurer, appellee, Wausau Insurance Companies. The commissioner allowed an additional recovery from the appellee, Second Injury Fund of Iowa, for industrial disability caused by a prior knee injury. On judicial review, the district court affirmed the award of permanent partial disability benefits and reversed the judgment against the Second Injury Fund.
