Heelpad degloving injuries are rare but functionally devastating phenomena, most commonly associated with high energy multi-trauma. The glabrous heelpad is a highly specialized tissue unit, adapted to withstand the mechanical stresses of weightbearing. In these injuries, depending on the degree of tissue loss from dieback, bone/fracture exposure and involvement of the weightbearing surface, free flap reconstruction is often warranted – however, there are no perfect donors - often resulting in bulky insensate reconstructions with chronic ulceration, sinuses and functional impediment – at the extreme (although not uncommonly) leading to elective extremity amputation.
Hence the merit of heelpad preservation and salvage manoeuvres are apparent i.e repair or reconstruction of the medial calcaneal branch of posterior tibial artery (MCPTA).
Case: 40 year old male with left open calcaneal fracture and heelpad degloving post jump off 2nd story during episode of drug induced psychoses – had primary anastomosis of 1x MCPTA branch – subtotal heelpad salvage with a small area of necrosis dressed to completion.
Literature on this topic is sparse. Graf et al describes the successful revascularization of 1 heelpad which demonstrated more physiologic biomechanics compared to a flap reconstructed heel.
Morii et al described 5 cases of “arterialization” of the plantar venous system, whereby a posterior tibial artery branch is vein grafted to a venous perforator on the heel; 3/5 had complete survival while the other 2 needed reconstruction- compared to 5/5 primary suturing that all had dieback requiring reconstruction.
We conclude that acute heelpad revascularization is indeed worthwhile - it is our unit’s practice to attempt it when practically viable and clinically appropriate.
