Abstract: Objective To analyze the relative factors of functional recovery after upper limbs replantation. Methods From September, 2009 to March, 2014, 24 consecutive patients after upper limb replantation for amputation were retrospectively analyzed. The Disability of Arm Shoulder and Hand (DASH) was used to assess the functional recovery of the upper limbs at the last follow-up. The non-conditional Logistic regression was used to analyze the correlation of gender, age, time from injury to surgery, amputated level, amputated method, ischemia hours, dominant hand or not, rehabilitation treatment, rehabilitation duration, and the DASH scores. Results The DASH score was > 28.50 in 15 patients, while ≤28.50 in 9 patients. The Logistic regression analysis demonstrated that amputated method and rehabilitation treatment correlated with the functional recovery of upper limbs (χ2>7.360, P<0.05), and no correlation was found in the other factors (χ2< 3.789, t=1.515, P>0.05). Conclusion The amputated method and rehabilitation treatment after operation are the factors related to the functional recovery after upper limb replantation.
