Innervated Cross-Finger Pulp Flap for Reconstruction of the Fingertip
نویسندگان
چکیده
BACKGROUND Fingertip injuries involving subtotal or total loss of the digital pulp are common types of hand injuries and require reconstruction that is able to provide stable padding and sensory recovery. There are various techniques used for reconstruction of fingertip injuries, but the most effective method is functionally and aesthetically controversial. Despite some disadvantages, cross-finger pulp flap is a relatively simple procedure without significant complications or requiring special techniques. METHODS This study included 90 patients with fingertip defects who underwent cross-finger pulp flap between September 1998 and March 2010. In 69 cases, neurorrhaphy was performed between the pulp branch from the proper digital nerve and the recipient's sensory nerve for good sensibility of the injured fingertip. In order to evaluate the outcome of our surgical method, we observed two-point discrimination in the early (3 months) and late (12 to 40 months) postoperative periods. RESULTS Most of the cases had cosmetically and functionally acceptable outcomes. The average defect size was 1.7×1.5 cm. Sensory return began 3 months after flap application. The two-point discrimination was measured at 4.6 mm (range, 3 to 6 mm) in our method and 7.2 mm (range, 4 to 9 mm) in non-innervated cross-finger pulp flaps. CONCLUSIONS The innervated cross-finger pulp flap is a safe and reliable procedure for lateral oblique, volar oblique, and transverse fingertip amputations. Our procedure is simple to perform under local anesthesia, and is able to provide both mechanical stability and sensory recovery. We recommend this method for reconstruction of fingertip injuries.

BACKGROUND Fingertip injury requiring flap cover is very common in the modern era. The ideal cover should fulfill both functional and aesthetic improvement. MATERIALS AND METHODS From June 2015 to April 2016, we performed seven free toe pulp flaps for finger defect reconstruction. All patients were males. Five flaps were done in emergency post-traumatic cases, and two were done in elective se...
متن کاملMacrosurgery for fingertip amputations
Due to the high concentration of sensitive receptors, the fingertip is widely used in plenty of activities and, therefore, frequently exposed to trauma and amputation. Simple revision amputation was used in the past for the treatment of these injuries. However, replantation, revascularization, or reconstruction allows preservation of the nail, length of the digit, and, mainly, sensibility of th...

We presented 59 fingertip injury cases that we treated and followed up. Among the 59 patients, 50 were male and 9 were female. The methods we chose for reconstruction were as follows: repairing by a skin graft (n:3), a V-Y advancement flap (n:17), a cross-finger flap (n:19), a thenar flap (n:5), an abdominal interpolation flap (n:8) and infraclavicular flap (n:2). We performed 35 operations und...
