Plaintiff assigns as error the granting of defendants’ motions for summary judgment. Summary judgment is appropriate if “the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that any party is entitled to a judgment as a matter of law.” G.S. 1A-1, Rule 56(c).
Plaintiff alleges that he was injured due to the negligence of defendants or their agents, yet he states' in his complaint that he does not know who caused the injury, how it happened, or when it happened, except that he alleges that it occurred while unconscious due to the anesthetic administered him. The depositions of Dr. Miller and those who assisted him in the operation failed to further clarify plaintiff’s allegations of negligence. The depositions disclosed that none of the deponents had any knowledge of any occurrence that could have caused the injury complained of; nor did any of the deponents even know that an injury had occurred until sometime after the operation.
In the deposition of Dr. Miller, he stated:
“ . . . It is correct to say that I know of nothing that occurred at the July 14th admission or during the operation or during the recovery room after the operation which produced or could have produced any injury to the ulna nerve in the left arm.”
In December 1968 the plaintiff was again admitted and Dr. Miller testified:
“ . . . I diagnosed his condition in my history and physical examination of December 8th admission as neuro-pathy of the ulna nerve on the left. The word neuropathy is a general term denoting functional disturbances and *122changes, and, or pathological changes in the peripherical [sic] nervous system. The etiology is not necessarily from a traumatic injury. It could be an etiological factor. Ischemic neuropathy and arsenical neuropathy could be a cause. Diabetes could also be a cause.
When I operated on the ulna nerve on his admission of December 8, 1968, I found that the nerve was irritable and that it was imbedded in scar tissue. I removed it from the tissue in which it was imbedded. We are talking about the funny bone nerve. There is a sheath around the nerve. We transferred the sheath with the nerve, but took it out of the tight tissue in which it was lying. We did find that it was imbedded in scar tissue. The words adhesions and scar tissue are used pretty much synonomously but there are certain differences, I suppose, technically. I describe this as scar tissue. I did this, so to speak, advisedly, because that’s what it looked like, as contra-distinguished from adhesions. When I think of an adhesion, I think more of a narrower band rather than a more extensive covering.
I suppose many things can cause scar tissue. One of the causes could be that the blood vessels in the area are broken and hemorrhage occurs. Scar tissue is a form of healing. You can have a blood vessel break and have healing without any scar tissue; you can also have one break and have scar tissue. That is correct but whether it comes from just the breaking of that or whether it comes from — it has got to be some type of tissue reaction, which is hard to explain, why one time you get trauma and another time, you don’t. This could be described as a partial ulna nerve paralysis.”
Dr. Miller concluded his deposition with the statement that he knew of nothing which could have caused the condition he found during the operation of December 1968. The record also discloses that the plaintiff was a diabetic.
The deposition of the plaintiff shows only that plaintiff had pain in his- left arm when he awoke in the recovery room. It does not reveal any further information as to how the injury occurred.
*123“To warrant the submission of a malpractice case to the jury, there must be proof of facts or circumstances which permit a legitimate inference of actionable negligence on the part of the physician .... A showing of an injurious result is not enough. ...” Boyd v. Kistler, 270 N.C. 744, 155 S.E. 2d 208 (1967).
In Boyd v. Kistler, supra, Justice Higgins, in affirming a judgment of nonsuit, went on to state:
“ ... By investigation, the plaintiff surely could have obtained evidence as to when and how the injury occurred and who caused it. No doubt the plaintiff's able counsel knew of their right to make inquiry by adverse examination of witnesses and the examination of documents.”
Here, the plaintiff has taken advantage of the discovery procedures available and has still been unable to obtain evidence as to when and how the injury occurred and who or what caused it.
In fact, the record does not reveal that any injury in the nature of an inflicted harm occurred, and the condition of the plaintiff could just as well have been from a pathological cause.
In the absence of a showing that there was a genuine issue as to any material fact, summary judgment was appropriate. The order of the trial judge granting defendants’ motions for summary judgment and dismissing the action is
Affirmed.
Judges Britt and Graham concur.
