Replantation vs revision amputation in single digit zone II amputations

Summary The objective of this study was to compare the functional outcomes of zone II amputations treated with either replantation or revision amputation at our institution to better aid patients in their decision making process regarding these treatment options. We conducted a comparative retrospective study. All cases of single digit amputations received at our replantation center between 2007 and 2011 were screened for single digit zone II injuries. These patients were stratified based on the treatment received: replantation vs revision amputation. Patients were called and invited to participate in the research project. Those who accepted to enter the study were asked to complete the Quick-DASH, the Beck Depression Inventory-short form, and a custom made questionnaire. There were seventeen patients with single digit zone II replantation and fourteen patients with similar injuries who underwent revision amputation and agreed to take part in the study. Our data revealed that the duration of sick leave, occupation after injury, professional and social reintegration, discontinued activities, and self-confidence were not statistically different between the two groups. The average hospital stay and the follow-up period of replanted individuals were longer. The replantation group did not have higher levels of pain or cold intolerance, and the global functional and esthetic satisfaction levels were similar between the two groups. Also, Beck Depression Inventory and Quick-DASH scores were not statistically different. Yet, significantly more patients in the replantation group would opt to repeat the replantation than revised patients would opt for revision amputation. From a functional viewpoint, our study suggests that revision amputation is not superior to replantation in zone II single digit amputations. This is valuable information that should be given to patients when deciding on the treatment process and to insure a proper informed consent.
