Clinical Context
A patient with a partial or complete amputation of one or more digits presents to a prosthetics clinic for fitting of a passive cosmetic prosthetic finger or thumb. Typical patients include those with traumatic amputation, congenital absence of a digit, or surgical digit loss after infection or tumor resection. The clinical workflow begins with an initial consult with a prosthetist or hand surgeon to assess residual limb shape, skin integrity, and patient goals for cosmesis and light function. Measurements and a mold or digital scan are obtained. A custom passive prosthetic digit or thumb (L6039) is fabricated by a certified prosthetist or prosthetic lab using silicone, polyurethane, or other materials. The patient returns for a fitting visit where the prosthesis is trimmed, color-matched, and fitted with suspension or adhesives as needed. Education on application, removal, skin care, and follow-up scheduling is provided. Follow-up visits address fit adjustments, replacement needs (wear or growth-related in pediatric patients), and potential functional prosthesis referral if greater activity is desired. Typical site of service is an outpatient prosthetics clinic or hospital-based prosthetics department; occasional fittings may occur in ambulatory surgical centers if concurrent procedures are performed.
