This appeal presents one question: Was the plaintiff/appellant required to present expert medical testimony on causation to support her claim of damages for pain and suffering allegedly caused by the negligence of hospital employees in transferring her onto a gurney for transport? We answer that question yes and no. The trial judge concluded that expert testimony was necessary to establish causation as to all aspects of appellant’s claim, and granted summary judgment to the defendants (hereafter “the Hospital”) when she did not designate such an expert. We conclude that, although expert testimony was required as to a key part of the causal link appellant alleged between the negligence and her injuries, she was entitled to go to a jury on the remainder of her claim without need for expert testimony on causation. We affirm in part and reverse in part, and remand for a trial.
I.
As alleged in her complaint and opposition to the summary judgment motion, plaintiff/ app ell ant Williams (hereafter *1002 Williams) was admitted to Sibley Memorial Hospital on November 1, 2001, to undergo a total left hip replacement. The surgery was performed on that date by Denis R. Harris, M.D., and Williams was returned to her room in the hospital. Immediately after the surgery, Hospital nursing staff had applied inflated, plastic sleeve-like devices, called circulation cuffs, to both of her legs to promote blood circulation. These devices were attached to plastic tubing and an air compressor to maintain adequate internal air pressure.
That same morning, two employees arrived with a gurney to be used to transport Williams to the radiology department of the Hospital. According to the complaint, the employees did not consult with the attending nurse, and no nurse was present to disconnect the cuffs before Williams was transferred to the gurney. Before the transfer, the employees did not remove the circulation cuff from her left leg, causing it to stay attached to the plastic tubing and air compressor. The complaint alleged that, despite Williams’ protests, the employees pulled her from the bed onto the gurney “with great force ... thereby dislocating the prosthetic hip joint within [her] left lower extremity, causing excruciating pain.” Williams alternatively claimed (particularly in opposing summary judgment) that, even if her hip had become dislocated from natural causes before the transfer to the gurney, the employees, by “pulling her onto the gurney without disconnecting the circulation cuff,” caused her “excruciating pain” during all or part of the next twelve hours.
Thereafter, Williams was taken to the radiology department where the left hip area was x-rayed and the prosthetic hip was found to be out of place and dislocated. As a result, according to the complaint, she “endured many hours of severe pain and discomfort until a second surgical procedure could be scheduled.” Approximately twelve hours after her transfer to the gurney, the prosthetic head and shaft were replaced in a second operation by Dr. Harris.
Dr. Harris testified in deposition that when he had visited Williams at about 7:30 a.m. following the original surgery, her replaced hip “seemed to be dislocated at that point in time” and she was in pain. For this reason, he ordered her to be transported for an x-ray to seek confirmation of the accident. Williams, by contrast, testified that at the time Dr. Harris visited her she was not experiencing pain, but when the employees tried to pull her onto the gurney, her pain was “immediate.”
II.
As explained, in her complaint Williams alleged principally that the negligence of the employees in transferring her had caused her replacement hip to become dislocated. For this negligence, she claimed damages not only for the pain and suffering she experienced in the succeeding hours, but also for the “substantial medical expenses” she incurred that stemmed partly from the second operation performed that evening. In moving for summary judgment, the Hospital contended that, even if its employees had been negligent in transferring Williams to the gurney, there were no triable issues of fact on causation because she had designated no medical expert to testify that the transfer, rather than natural causes such as movement in bed following a hip replacement performed on a woman with a conceded long history of back surgery, had caused the hip to become dislocated. This testimony was indispensable, the Hospital argued, in light of Dr. Harris’s testimony that the hip already appeared to be dislocated when he visited her that morning— which, indeed, was why he ordered her transported to radiology for an x-ray. The *1003 trial judge agreed that expert testimony was necessary to establish causation between the negligent transfer to the gurney 1 and the dislocation of Williams’ hip. We think the judge was correct in that regard.
Although “[t]here is no inflexible requirement in a personal injury case that the plaintiff produce expert medical testimony on causation,”
Williams v. Patterson,
This conclusion, however, does not mean that the Hospital was entitled to summary judgment altogether. As we have explained, Williams’ alternative claim in the pleadings, and the one she now presses on appeal, is that the act of forcing her onto the gurney against the restraint of the circulation cuff caused, or at least substantially contributed to, the intense pain and suffering she endured over the next twelve hours even if the hip had already become dislocated.
See, e.g., District of Columbia v. Freeman,
“[EJxpert medical testimony on the issue of causation [is] not ... necessary” when the medical question presented is not a “complex” one.
Bushong v. Byung Kyu Park,
The Hospital cites our decision in
Williams v. Patterson, supra,
as requiring expert testimony on this point, but we do not agree.
Patterson
recognized and applied traditional principles of aggravation “requiring] a jury to differentiate between a present medical condition and a preexisting one in evaluating the causal role of an intervening accident”; and it held, on the facts presented there, that expert testimony was necessary to help the jury identify those
“increased or augmented
sufferings proximately resulting from the accident [that alone] are compensable in court.”
Patterson,
Such permanency in the aggravation setting, especially where the natural progression of the preexisting condition must be taken into account, will ordinarily not be obvious, thus requiring the testimony of medical witnesses to establish both the fact of a permanent aggra *1005 vation and causation attributable to the defendant.

(quoting M. Minzer, et al., Damages in Tort Actions, Vol. 2 § 15.33[1], at 15-80);
see also id.
(quoting
Rehnke v. Jammes,
Williams’ case involves no such complicated history of causation leading to injuries claimed to be permanent. Her jury would be asked to decide only whether any negligence of the employees contributed to pain and suffering that she experienced over a period of hours, not longer; the more complex question of what had caused the dislocation of her new hip — and the resulting need for a second hip replacement and damages associated therewith— would not be before the jury. In these circumstances, we hold that expert testimony is not required before Williams may present her claim for limited damages to a jury-
Affirmed in part and reversed in part, and remanded for trial.
Notes
. For purposes of summary judgment, the Hospital effectively conceded that the employees had negligently transferred Williams to the gurney.
