On-top and side-to-side plasties for thumb polydactyly

Abstract

Highlights“On-top” and “side-to-side” plasties are techniques used for treating thumb duplications.The functional results of these techniques have not been reported in the literature.We report on two cases and document excellent functional results.

Wassel VI Duplications: A Report of 2 Cases, Soft-tissue Anatomy, and Reconstructive Approach

“…Given the even more unusual and complex variant—a combination of Wassel VI and Wassel VII subtypes—the authors focused on bony reconstruction and did not provide a description of soft-tissue anatomy or reconstruction. 8 In this article, we add to the literature by presenting 2 patients with a Wassel VI thumb duplication and describe our surgical approach to reconstruction particularly of the soft tissue anatomy.…”

“… 6 , 7 Additionally, operative techniques are often broadly descriptive for all forms of duplication rather than specific to the Wassel VI. 8 Shen et al 9 described a surgical technique for Wassel VI duplications; however, they focused on complex bony reconstruction without addressing soft-tissue reconstructive elements. To our knowledge, there are no studies describing the critical surgical techniques for soft-tissue reconstruction in Wassel VI duplications.…”

Evaluation and Management of Preaxial Polydactyly

“…The general methods of surgical correction for thumb duplication have been previously outlined by Tonkin, and their utilization is dictated by complexity, size, and location of the anatomical abnormality [22]. Studies on specific procedure type, surgical approach based on certain Wassel-Flatt classification types, and surgical techniques have been extensively described elsewhere [3,[33][34][35][36][37][38][39]. In brief, the primary goal of thumb reconstruction is to obtain stability, mobility, alignment, proper size, and proper shape.…”

“…Preserving the neurovasculature function of the distal segment requires immense precision given the risk of vascular compromise with this procedure. These procedures and specific associated modifications are further described in depth elsewhere [6,8,[34][35][36]38]. Following surgical reconstruction, in most cases, a long-arm thumb spica cast is applied for approximately 4 weeks.…”

Spare-Part Vascularized Bone Flap in the Management of Ulnar Ray Deficiency

“…The spare-part principle is commonly used in the surgical management of other congenital abnormalities such as thumb duplication and synpolydactyly. 1,2 Another indication for using the spare-part principle is hand trauma. The bones from a crushed finger is removed, preserving the blood supply the skin envelope.…”
