Kamran Tavakoli-Nouri appeals from the trial court’s decision to grant appel-lees’, Stephen F. Gunther, et al, motion for summary judgment. The trial court granted appellees’ summary judgment motion because Tavakoli-Nouri failed to timely file a Super. Ct. Civ. R. 26(b)(4) statement listing his expert witnesses and the testimony upon which he intended to rely at trial. The trial court granted the motion after denying Tavakoli-Nouri’s motion to extend the time to file the required Super. Ct. Civ. R. 26(b)(4) statement. In granting the motion for summary judgment, the trial court found that without expert testimony to establish the requisite duty of care he was owed or to establish that a breach of that duty of care occurred, Tavakoli-Nouri could not present sufficient evidence to prevail on his medical malpractice claims as a matter of law. On appeal, Tavakoli-Nouri argues, that: 1) the trial court improperly dismissed his claims of medical malpractice, abandonment, and lack of informed consent on summary judgment because the use of expert testimony was not required; and 2) the trial court erred in ruling on the summary judgment motion in his absence. After a review of the repord, we affirm the trial court’s dismissal of the medical malpractice and abandonment claims, but reverse the trial court’s ruling dismissing Tavako-li-Nouri’s remaining claim of lack of informed consent.
I. FACTUAL SUMMARY
Tavakoli-Nouri was injured in an automobile accident in September of 1993. He was originally transported to Prince George’s Hospital Center, but was subsequently transferred to Washington Hospital Center where he received inpatient care in September and October of 1993. Tavakoli-Nouri underwent surgery at the Washington Hospital Center. Stephen F. Gunther, M.D. performed the operation on Tavakoli-Nouri’s knee and Dr. DiPasquale performed the operation on his pelvis. Ta-vakoli-Nouri asserts that he suffered penile deformity, impotence, urologic dysfunctions, hernia enlargement, and unsutured *941 rectus fascia muscle from the pelvic operation; as well as nerve injury to his right leg and toes claw deformity as a result of the surgery on his knee. Tavakoli-Nouri brought a medical malpractice suit against appellees on September 25, 1996, alleging that the doctors and the Washington Hospital Center: 1) were negligent when they performed the operations on his knee and pelvis; 2) abandoned him in violation of the established standard of medical care; 3) performed the surgery on his pelvis without his permission; and 4) performed the surgery of his knee without adequately informing him of the adverse consequences of the surgery.
II. STANDARD OF REVIEW
In reviewing a trial court order granting a summary judgment motion, we conduct an independent review of the record, and apply the same standard of review used by the trial court in the first instance.
Sherman v. District of Columbia,
III. ANALYSIS
Tavakoli-Nouri alleges that expert testimony was not required for his claims of medical malpractice for the surgery on his knee and pelvis against appellees. “In medical malpractice actions, expert testimony is usually required to prove the appropriate standard of care and causation.”
Miller v. Greater Southeast Community Hospital, et al.,
Similarly, Tavakoli-Nouri argues that the trial court erred in dismissing his claim of abandonment based on his failure to retain an expert witness. Abandonment involves the “termination of the professional relationship between the physician and patient at an unreasonable time or without affording the patient the opportunity to procure an equally qualified replacement.”
Miller,
*942
Tavakoli-Nouri’s complaint alleges two separate causes of action for lack of informed consent. His first claim alleges that Doreen DiPasquale, M.D. operated on his pelvis without his consent to perform the surgery. Because this is not a claim of lack of informed consent based on negligence, but is rather a claim that Dr. Di-Pasquale committed a common law battery, this claim is.governed by a one-year statute of limitations and is time-barred.
See
D.C.Code § 12-801(4) (1981). However, Tavakoli-Nouri’s second claim of lack of informed consent against Dr. Gunther for negligently failing to disclose the possible adverse consequences of the surgery was timely filed within the requisite three-year statute of limitations. D.C.Code § 12-301(8).
See Anderson v. Jones,
Tavakoli-Nouri argues that no expert witness testimony was necessary for his claim of lack of informed consent against Dr. Gunther because his amended complaint alleges that “Gunther and his residentf] doctors failed to tell plaintiff any information before the knee surgery ... about the possible] ... occurrence of ... additional deformities and impairments ....” Tavakoli-Nouri contends that because he was not given
any
information before the surgery about the risks involved in the surgery, appellees could not have obtained his informed consent. Tavakoli-Nouri relies heavily on a 1972 decision by the United States Court of Appeals for the District of Columbia Circuit to support his argument that expert testimony was not necessary for him to proceed on this cause of action. In
Canterbury v. Spence,
150 U.S.App. D.C. 263, 283,
*943
Finally, Tavakoli-Nouri argues that the trial court abused its discretion by granting appellees’ motion for summary judgment in his absence.
3
As a preliminary matter, there is no requirement that a trial court judge conduct a hearing before it rules on a motion for summary judgment, and Tavakoli-Nouri proffers no authority to the contrary. In any event, this court has held that where there has been evidence of a pattern of dilatory conduct, dismissal is not an abuse of discretion.
See generally Dobbs v. Providence Hospital,
IV. CONCLUSION
Tavakoli-Nouri had not and could not, without further leave of the court, produce sufficient evidence to create a material issue of fact for a jury on the questions of medical malpractice and abandonment. Therefore, appellees’ were entitled to summary judgment on those issues as a matter of law. However, because expert testimony was not required to establish his cause of action for lack of informed consent and a material issue of genuine fact remained as to whether any information was disclosed to Tavakoli-Nouri regarding his knee surgery, summary judgment was not appropriate on this issue.
Accordingly, this case is hereby
Affirmed in part and reversed and remanded in part.
Notes
. Although
Canterbury
was decided by the United States Court of Appeals for the District of Columbia Circuit after February 1, 1971,
see M.A.P. v. Ryan,
. It is important to note that in the
Eibl
case, the nature of the risks were uncontested, and the credibility question that could be established by lay witness testimony was whether or not the doctor actually informed the patient of this information. However, even if Tavakoli-Nouri’s allegation is that he was not sufficiently informed, he was not required to present independent expert testimony to establish what material risks required disclosure. This court held in
Abbey v. Jackson,
. Tavakoli-Nouri also argues that the trial court abused its discretion because it failed to carefully consider counsel's representation that he would enter a formal appearance upon the reopening of discovery. However, we find no merit in this argument because the record clearly shows that the trial court, in reaching its decision, considered counsel’s representations on December 19, 1999, Tava-koli-Nouri’s past failure to adhere to deadlines, Tavakoli-Nouri’s failure to appear at scheduled hearings, and the prejudicial consequences to appellees’ by granting another time extension in this case.
