Composite grafts for fingertip amputations: A systematic review protocol

Background: There is much debate in the hand surgery literature as to the management of fingertip amputations. Much research continues to be published in this area. Methods of reattachment include microsurgical and non-microsurgical (composite graft) replantation. The role of composite grafts lacks clarity in terms of outcomes, success rates and complications. Hence there is a need for an evidence synthesis, which can guide patient selection, the consent process and determine graft survival rates and functional outcomes to optimise patient outcomes.

Methods: Search of the databases OVID MEDLINE, PubMed, EMBASE, SCOPUS, The Cochrane Library and clinical trial registries from inception using terms "fingertip" "digital tip" "digit" "finger" "thumb" "amputation" "replantation" "reattachment" "reimplantation" and "composite graft" as key terms with "AND" selected as a Boolean operator, limited to humans will be conducted by two independent researchers. The patient population will include adults and children. Studies will be included if they report: (1) primary data; (2) outcomes of 'composite grafts' or 'nonmicrosurgical replantations'; (3) graft survival, (4) 5 or more cases. Articles will be excluded if surgical techniques involve: (1) composite graft pocketing, or (2) microsurgical replantation or (3) additional flaps (pulp or local). Full exclusion and inclusion criteria are described within this protocol. Data extraction will include; demographic details, patient comorbidities, amputation nature and level, functional, and aesthetic outcomes, complications and need for secondary procedures. All data extracted will be cross-checked, and discrepancies resolved through consensus.

Dissemination: This review will be published in a peer-reviewed journal and will be presented at national and international conferences to inform the practice of other clinicians.
