A Systematic Review of Outcomes after Revision Amputation for Treatment of Traumatic Finger Amputation

Abstract

Background Revision amputations are often the treatment for traumatic finger amputation injuries. However, patient outcomes are inadequately reported, and their impact poorly understood. We performed a systematic review to evaluate outcomes of revision amputations and amputation wound coverage techniques. Methods We searched all available English literature in PubMed and EMBASE for articles reporting outcomes of non-replantation treatments for traumatic finger amputation injuries, including revision amputation, local digital flaps, skin grafting, and conservative treatment. Data extracted were study characteristics, patient demographic data, sensory and functional outcomes, patient-reported outcomes (PROs), and complications. Results 1659 articles were screened, yielding 43 studies for review. Mean static 2-point discrimination (2-PD) was 5.0 ± 1.5 mm (n=23 studies) overall. Mean static 2-PD was 6.1 ± 2.4 mm after local flap procedures and 3.8 ± 0.4 mm after revision amputation. Mean total active motion (TAM) was 93 ± 8% of normal (n=6 studies) overall. Mean TAM was 90 ± 9% of normal after local flap procedures and 95% of normal after revision amputation. 77% of patients report cold intolerance after revision amputation. 91% of patients (217/238) report “satisfactory” or “good/excellent” ratings regardless of treatment. Conclusion Revision amputation and conservative treatments result in better static 2-PD outcomes compared to local flaps. All techniques preserve TAM, although arc of motion is slightly better with revision amputation. Revision amputation procedures are frequently associated with cold intolerance. Patients report “satisfactory,” “good,” or “excellent” ratings in appearance and quality of life with all non-replantation techniques. Level of Evidence III

Osseointegrated Finger Prostheses Using a Tripod Titanium Mini-Plate

“…The loss of any digit has functional, aesthetic, and psychological sequelae [21115]. In circumstances where digital reconstruction is anticipated, autologous reconstruction should be considered the gold standard [2312].…”

Digit Tip Injuries: Current Treatment and Future Regenerative Paradigms

“…Closure can be performed directly with or without revision amputation/bone shortening by using local skin flaps or tissue grafting (sometimes with the amputated part itself). A systematic review by Yuan et al showed that 91% of patients undergoing revision amputation with or without local flaps were satisfied with their result and maintained an acceptable range of motion [62]. However, the closure of skin flaps has been shown to inhibit the regenerative response.…”

Improved Abdomen Hypodermic Embedding for Salvage of the Amputated Fingertip from Tip to Lunula (Tamai Zone Ⅰ)

“…It can achieve almost normal sensibility and satisfactory motion [6]. However, it also has many disadvantages, such as frequent cold intolerance [7], painful neuroma formation [8], shortening of the ngers and poor appearance. It cannot be accepted by many Asians especially female patients.…”

“…The ap repair can ensure that the nger will not shorten, but there are also many kinds of drawbacks such as poor appearance, large damage, poor sensitivity [7] and poor mechanical properties of the ap.…”
