Edgerton v. Morrison

Summary

The Missouri Supreme Court affirmed a judgment against a cardiothoracic surgeon in a medical negligence action involving the failure to diagnose and treat an unstable, necrotic sternum after cardiac bypass surgery. The Court held that the verdict director, verdict form, and damages instruction were proper and that sufficient evidence supported causation, including evidence that earlier diagnosis could have allowed a preferable rigid repair procedure.

Holdings

1. The verdict director was proper because, in the context of the evidence and arguments, the term "rigid fixation" provided a sufficient factual guideline and referred to the two rigid procedures available to Edgerton.
2. The verdict form was proper because the added phrase "as submitted by Instruction No. 11" merely identified the claim corresponding to the defendant and did not misdirect, mislead, or confuse the jury.
3. The damages instruction did not warrant reversal because the jury was instructed to harmonize and apply the instructions as a whole, and it found no other defendant liable for damages under the referenced instructions.
4. The evidence was sufficient to support the jury's finding that the defendants' negligent failure to diagnose the sternum condition caused Edgerton injury by depriving him of the opportunity to receive a preferable rigid repair.

Questions Presented

1. Whether the verdict director's use of the term "rigid fixation" improperly gave the jury a roving commission.
2. Whether the verdict form was improperly modified by adding the phrase "as submitted by Instruction No. 11."
3. Whether the damages instruction improperly permitted an award for damages attributable to other defendants.
4. Whether the evidence was sufficient to establish that the defendants' negligent diagnosis caused Edgerton's injury and supported denial of directed-verdict, judgment-notwithstanding-the-verdict, and new-trial motions.

Disposition
