In DeLong v Hampton Envelope, 149 S.W.3d 549 (Mo.App.E.D. 2004), claimant sustained a work injury which required an amputation of her left middle finger at her distal joint. Dr. Dunn performed replantation surgery to reattach the finger but it was unsuccessful. Dr. Dunn then had to perform revision amputation surgery to remove the injured part of the finger. Dr. Dunn prescribed a custom made prosthetic finger for the claimant. However, the employer/insurer denied that the claimant had any medical need for the prosthesis and refused to provide it. Dr. Brown for the employer testified that he did not believe the prosthesis is necessary to improve the function of claimant’s hand or finger. Claimant testified that the prosthesis would help her physically and psychologically and emotionally to feel less embarrassed. The Court found that the employer is under a statutory duty to provide the claimant with the prescribed prosthesis and future medical care related to the maintenance, care, and replacement of the prosthesis because it will relive claimant of the negative effects associated with her amputated finger and the claimant will receive functional benefits from the prosthesis both physical and psychological. Affirmed.
