Perforator-based Reverse Radial Teno-Adipo-Fascial Flap: Surgical Technique and Case-report for the Functional Reconstruction of the Dorsum of the Hand

Background Dorsal complex cutaneotendinous lesions of the hand represent a reconstructive challenge. The use of composite microvascular flaps and vascularized tendon grafts represent the gold-standard. The radial anti-brachial region can still represent an excellent donor site, to the detriment of the possible sacrifice of the radial artery. The reverse radial anti-brachial flap can be either perforator-based, thus saving the radial artery or raised as an adipo-fascial flap, to spare the skin. Patients and Methods A case of post-traumatic highly contaminated dorsal cutaneotendinous defect of the second ray of the hand was reported. An original surgical reconstructive technique with a Revers Radial Teno-Adipo-Fascial Flap (RRTAFF) plus vascularized Palmaris Longus was described, preserving the radial artery. A simple partial thickness skin graft was performed a second time to complete dorsal cutaneous coverage. A subsequent infection was managed by trusting the complete vascularization of the tissues used for the reconstruction. Results The hand healed well with containment of the infection. The dorsal healed skin appeared elastic and pliable enough. Passive and active motion of interphalangeal and metacarpofalangeal joints were very satisfying. The donor site was well healed, with almost no morbidity. Conclusions This reconstructive strategy provides a quick and straightforward single-stage option for the reconstruction of complex cutaneotendinous defects of the dorsum of the hand. Such a reconstruction, with a completely vascularized procedure, is particularly indicated in cases of high contamination or infection of the recipient site.
