This is a workmen’s compensation case. Plaintiff alleges that he was an employee of the defendants when on August 3, 1954, he suffered an accident to his back resulting in a herniated and ruptured disc; that the injury was not discovered until September 1955; that he underwent an operation in October 1955; and that he suffered temporary total and permanent partial disability therefrom. He seeks compensation, hospital and medical expenses, and attorney’s fees under the Workmen’s Compensation Act.
The defense, so far as important here, is that the injury and disability resulted from an accident in *237 the course of plaintiffs employment in September 1955, when plaintiff was the employee of other parties who have a different insurance carrier.
The matter was heard before one judge of the compensation court, resulting in a dismissal of the plaintiff’s cause. The matter was appealed to the district court and again resulted in a dismissal of plaintiff’s cause. Plaintiff appeals here.
We affirm the judgment of the trial court.
The cause is here for trial de novo on the record. Anderson v. Cowger,
Preliminary to a statement of the evidence there are other matters which must be determined. In their answer in the district court, defendants denied generally, pleaded the statute of limitations, pleaded that plaintiff had sustained an accidental injury on September 20, 1955, while no longer an employee of the defendants, and alleged that said second accidental injury was the sole and proximate cause of any disability of plaintiff. Plaintiff moved to strike the allegation in defendants’ answer as to the September 1955 injury. The basis of this motion was that it was an affirmative defense which had not been pleaded in the compensation court and was the raising of a new issue.
The trial court sustained the motion. The cause went to trial on the general denial and plea of the statute of limitations.
The court admitted evidence of the second injury based on statements of the plaintiff as admissions against interest.
The trial court held that plaintiff had failed to sustain his burden of proof.
As will appear in the discussion of the evidence, the question of the admissibility and consideration of the evidence of the second injury is important to a determination of the questions presented here.
Plaintiff’s contention is that the evidence as to the second injury was erroneously admitted, and should *238 not have been considered by the trial court and cannot be considered here.
Plaintiff argues here that section 48-176, R. R. S. 1943, requires that the defendant by answer either admit or deny the substantial averments of the petition; that he “shall state the contention of the defendant with reference to the matters in dispute”; and that the quoted language required the defendant to plead the second injury in the compensation court if it was to be relied upon as a defense.
The concluding phrase of the sentence in section 48-176, R. R. S. 1943, is “as disclosed by the petition.” Plaintiff quotes the clause. He then quits reading too quickly. Section 48-173, R. R. S. 1943, sets out the contents of a petition for compensation concluding with “also stating the matter or matters in dispute and the contention of the petitioner with reference thereto.”
At most, the defendants would be required only to state their contentions with reference to the matters in dispute “as disclosed by the petition.”
Here the plaintiff did not state the second injury and its results as a matter in dispute, nor his contentions in reference thereto. The statute has no application here. We need not construe it further than to reach that conclusion.
It is suggested in the briefs that the foundation of the trial court’s ruling on the motion to strike and the contention that the fact of a second injury was an affirmative defense which had to be pleaded rests upon our decision in Otoe Food Products Co. v. Cruickshank,
An analysis of that case shows that it was misconstrued. In that case the employer was the plaintiff. The employer alleged that the employee had received an eye injury and that he had been paid temporary total disability compensation and medical expenses. The employer then alleged a second accident and injury and that the second accident was not suffered in the course of employment by the plaintiff. The second accident and injury as the proximate cause of the employee’s loss of vision was the basic fact put in issue by the plaintiff employer. We held correctly that it was an affirmative allegation which the employer was required to prove to sustain his petition. The decision does not hold that a second injury is an affirmative defense which has to be pleaded if relied upon.
The long-established rule is: “When an answer to a petition consists of a general denial, the defendant may introduce such testimony as will tend to disprove the testimony of the plaintiff in support of his petition. For such purposes no other allegations in the answer are necessary.” Alberts v. Pickard,
In that case the petition alleged the sale of an automobile to a minor. We held that under a general denial evidence to the effect that the minor was not the purchaser of the automobile was admissible.
The rule above was stated originally in Broadwater v. Jacoby,
Wiedeman v. Hedges,
Hughes Co. v. Farmers Union Produce Co.,
So here we hold that evidence of the accident and resulting injury of September 1955 as the proximate cause of plaintiff’s disability was admissible under the general denial. It tends directly to contradict the allegations of the plaintiff’s petition that the accident of August 1954 was the cause of his injury and present disability. That evidence is for consideration here.
The fact situation here is not in serious dispute.
The plaintiff at the time of the hearing was 34 years of age. He had some time prior to the first accident, later referred to herein, suffered from “charlie horses” or muscle cramp in his legs. There is evidence that could relate these incidents to beginning after he had played football in his high school days. At any rate he testifies that they occurred not frequently, but prior to August 3, 1954. At that time plaintiff was an employee of the defendants as a carpenter. A rock slide occurred and a rock hit his lower back causing bruises and muscle injury. He was examined by defendants’ doctor, and normal X-rays were taken. No severe' injury was found. He was found to be able to resume his regular employment and did so for the following 6 or 8 weeks. He did not again ask for medical care although he had treatments by a chiropractor for a few *241 times. He was then “laid off.” During the following months he lost weight rapidly and then regained it by private medical treatment. We find no' contention that the loss of weight had anything to do with his present disability.
He began work as a carpenter in March 1955 for a different employer, not a party to this proceeding. He worked as a carpenter and carpenter foreman for this second employer until September 21, 1955. During this period the frequency and severity of the “charleyhorse” trouble increased somewhat but was in nowise disabling.
On September 21, 1955, a scaffold fell on plaintiff striking his right thigh above the knee. It was not disabling. This accident was not reported to the plaintiff’s employer. However, pain developed after the accident in his leg and back. Plaintiff went to the doctor September 22, 1955, with severe and disabling pain. He was hospitalized September 24, 1955, and during the period of the examination gave the doctor the history of the accident of September 21, 1955. It was noted in his history on the hospital records and the physician testified to the fact that plaintiff told him of it. Plaintiff does not deny the statement or the fact of the second accident.
On Sepember 30, 1955, a myelogram revealed disc trouble in his lower back. On October 13, 1955, an operation was performed on plaintiff. The doctors found that he had a herniated disc and a ruptured disc.
Plaintiff made a normal recovery from the operation. It was followed by temporary total disability and there is a claim of partial permanent disability. The doctors who testified did not entirely agree on the differences between a herniated disc and a ruptured disc. They did substantially agree that a herniated disc may be congenital, caused by defective structure in the bones of the spine, or caused by trauma. They agreed that a herniated disc may be a condition of long stand *242 ing and not necessarily disabling or revealing of its presence.
They agreed also that a ruptured disc makes its presence known almost immediately and often by severe and quite disabling pain.
Plaintiff’s expert witnesses testified that in their opinions the accident of August 3,1954, set up the groundwork of the herniated disc that later developed into the disabling situation of September 1955.
Defendants’ expert witness doubted if the injury of August 3, 1954, had anything to do with the disc condition. He also held that the accident of September 21, 1955, “could be the precipitating factor,” followed as it was by the disability. He further testified that a ruptured disc could occur without a previously existing herniated disc.
Plaintiff’s doctor, who examined plaintiff in September 1955, testified that in his opinion the injury of' August 3, 1954, would be a cause of pain in his back and legs “if he sustained a ruptured intervertebral disc.” He further testified that, absent “other history of injury,” based on the history given him, it was his opinion that plaintiff was suffering from a ruptured or herniated disc from sometime in 1954. On cross-examination one of plaintiff’s doctors testified that a ruptured disc usually gives rather quick symptoms and that he doubted that the ruptured disc was caused by the accident of August 3, 1954. He further testified that the accident of September 21, 1955, “undoubtedly produced acute changes * * * That made it impossible for” plaintiff to work. He concluded with the opinion that “the injury of September 1955 was a very probable contributing factor and caused the rupture of the disk (sic)”; that the August 1954 injury “laid the groundwork so that another accident could create the total disability”; and that the rupture of the disc created the total disability.
The evidence shows, at most, that plaintiff suffered *243 an accident on August 3, 1954, which resulted in- a herniated disc condition in his back; that this situation, existed in March 1955 when he went to work for an employer, not a party to this action; and that it continued up until September 21, 1955, when he suffered the accident that was the cause of the disability for-which he seeks compensation.
The question is: Must the 1954 employer respond and pay compensation benefits under the Workmen’s Compensation Act?
Plaintiff relies on the rule stated in Tippett & Bond v. Moore,
We adopt the rule. It, however, requires amplification as to the determination of what constitutes “an independent intervening cause.”
The Supreme Court of Michigan answered that question in Brinkert v. Kalamazoo Vegetable Parchment Co.,
Here it is manifest that the first accident did not cause the second accident. The disability, as dis *244 tinguished from the condition, resulted from the second accident.
Plaintiff relies on Otoe Food Products Co. v. Cruickshank, supra. There we concluded that the second accident under the facts was not an independent intervening cause of plaintiff’s loss of vision.
Plaintiff relies further on Tippett & Bond v. Moore,
supra,
and Deep Rock Oil Corp. v. Betchan,
The above decisions must be analyzed in the light, of the fact that the appellate court was required to accept the findings of fact made by the commission if supported by competent evidence.
In Tippett & Bond v. Moore, supra, the commission found that the second “occurrence” was a “recurrence of the original injury.” The appellate court found competent evidence to support the finding and affirmed the award.
In the Deep Rock Oil Corporation case there was an accident with resulting compensable injury. There was: a later “incident” which the employer claimed was a subsequent and noncompensable injury. The court held that: “Not every incident following an injury which physically aggravates it can be treated as a responsible intervening agency.” The court affirmed the order of the commission, as sustained by the record, in disregarding the second incident as a responsible cause. In doing so, the court relied upon Head Drilling Co. v. Industrial Accident Commission,
In its decision the California court referred to Pacific Coast Casualty Co. v. Pillsbury,
This distinction is made clearer in the cases that followed in the Oklahoma court.
In Rialto Mining Co. v. Perry,
In Sutton & Sutton v. Courtney,
In Sigler v. Tillery & Jones (Okl.),
Plaintiff, also relies upon Continental Casualty Co. v. Industrial Commission,
Plaintiff relies further on Jarrett v. Travelers Insurance Co. (Tex. Civ. App.),
Plaintiff further relies on Phillips v. Holmes Express Co.,
When analyzed the plaintiff’s cases sustain the rule ■that there must be a causal relationship between the first accident and injury and the second accident in order to sustain ah award such as is sought :here.
The rules are: “In order to recover, the burden of proof is upon' the claimant in a compensation case to establish by a prépondérance of the evidence that personal injury was^ sustained by the employee by an acci
*247
dent arising out of and in the course of his employment. * * * An award of compensation under the Workmen’s .Compensation Act may not be based on possibilities, probabilities, or speculative evidence.” Jones v. Yankee Hill Brick Manuf. Co.,
The necessary conclusion is that plaintiff has not met the requirements of the burden of proof.
The judgment of the trial court is affirmed.
Affirmed.
