Mesovascularized Island Flexor Tendon

Reconstruction of the Flexor Pollicis Longus Tendon with Vascularized Tendon with Ulnar Artery Preservation

“…The vascular anatomy of the gliding tissue around the FDS has been extensively studied, and it is the vascularized tendon of choice. 9,10,18,19 Based on the anatomical studies of the vascularity of the carpal synovial sheath, a constant branch is described immediately proximal to the pisiform bone (Fig. 1).…”

“…The technique follows the general steps of the original technique described by Guimberteau 9 with modifications that avoid division of the ulnar artery, making it more attractive to hand surgeons. Through a Bruner incision, the remnants of the FPL are resected from the digital canal in the thumb, preserving the oblique pulley if present, and otherwise reconstructing the annular pulley.…”

“…Single-stage reconstruction using vascularized tendons was described by Guimberteau in 1992 with good results, although the technique did not receive much attention. 9,10 According to Guimberteau 9 the flexor digitorum superficialis (FDS) tendon and its surrounding lax connective tissue can be transferred as a composite vascularized gliding unit, pedicled on a branch of the distal ulnar artery (which must be divided), for single-stage reconstruction. The FPL has also been reconstructed with this technique, with overall worse results compared with triphalangeal digits.…”

Neurobiological tensegrity: The basis for understanding inter-individual variations in task performance?

“…Superficial fascia is a thin loose connective tissue that often separates anatomical structures, while deep fascia is dense connective tissue (C. Stecco et al, 2008). Guimberteau (2001Guimberteau ( , 2010 established the connection between the different layers with an impressive video analysis of a gliding system, a space filled with a vascularized collagen network that connects superficial and deep fascia. This network connects deeper and superficial tissue, allowing them to function differently and having a high proteoglycan content that behaves like a gel.…”

“…This network connects deeper and superficial tissue, allowing them to function differently and having a high proteoglycan content that behaves like a gel. This neurobiological property can only be observed in live or fresh tissue, and is, therefore, beyond the anatomical analysis usually performed in cadavers (Guimberteau, 2001;Guimberteau, Delage, McGrouther, & Wong, 2010).…”
