Concentrated autologous bone marrow injection in the surgical treatment of scaphoid non-union.

New surgical techniques for the treatment of scaphoid non-union, developed in the last two decades, now enable a healing rate of 80-90%. However, no consensus exists for the surgical treatment of non-union. On the other hand, regenerative medicine techniques have enriched the therapeutic armamentarium for non-union, especially in the lower limbs, with the use of autologous concentrated bone marrow injection using autologous osteogenic precursors to create a favorable microenvironment for bone healing.

Vascular supply of the radial nerve and its terminal branches: an anatomical study.

Purpose: The aim of this cadaveric study was to further describe the vascular supply of the radial, posterior interosseous and superficial radial nerves.

Methods: 11 cadaveric upper limbs, injected with colored latex, were dissected. Vascular afferents to the radial nerve, superficial radial nerve (SRN) and posterior interosseous nerve (PIN) were described and located.

[Anatomical cartography of the radial nerve at the elbow level for intraradial nerve transfers for finger extension reconstruction in spastic upper limb - A cadaveric study].

Introduction: Upper limb spasticity is a surgical challenge, both in diminishing agonists spasticity and reconstructing antagonist function. Brachioradialis (BR) is often involved in elbow flexors spasticity. Finger extension is often impaired in spastic patients.

Biomechanical characterization of cadaveric brachial plexus microstructure.

Introduction: Peripheral nerves consist of axons and connective tissue. The amount of connective tissue in peripheral nerves such as the brachial plexus varies proximally to distally. The proximal regions of the brachial plexus are more susceptible to stretch injuries than the distal regions.

Biomechanical characterization of cadaveric brachial plexus regions using uniaxial tensile tests.

Introduction: The proximal regions of the brachial plexus (roots, trunks) are more susceptible to permanent damage due to stretch injuries than the distal regions (cords, terminal branches). A better description of brachial plexus mechanical behavior is necessary to better understand deformation mechanisms in stretch injury. The purpose of this study was to model the biomechanical behavior of each portion of the brachial plexus (roots, trunks, cords, peripheral nerves) in a cadaveric model and report differences in elastic modulus, maximum stress and maximum strain.
