The surgeon, who treats nerve injuries, should have knowledge about how peripheral nerves react to trauma, particularly an understanding about the extensive pathophysiological alterations that occur both in the peripheral and in the central nervous system. A large number of factors influence the functional outcome, where the surgeon only can affect a few of them. In view of the new knowledge ab...

Nerve transfers are key components of the surgeon's armamentarium in brachial plexus and complex nerve reconstruction. Advantages of nerve transfers are that nerve regeneration distances are shortened, pure motor or sensory nerve fascicles can be selected as donors, and nerve grafts are generally not required. Similar to the principle of tendon transfers, expendable donor nerves are transferred...

IMPORTANCE Corneal anesthesia is recalcitrant to conventional treatment and can lead to permanent visual loss. OBJECTIVE To assess the outcomes of a novel sensory reconstructive technique for the treatment of corneal anesthesia. DESIGN, SETTING, AND PARTICIPANTS This prospective study evaluating a new technique was conducted at a tertiary referral center. Four eyes in 3 patients with cornea...

excessive scarring; paralleling the process in tendon reconstruction of the hand. inspired by the advantages of the two-stage technique in tendon grafting and with encouraging preliminary results, we aimed to investigate the two-stage nerve grafting technique as an alternative method of secondary nerve repair. methods:  thirty female rats (~200 g) were randomly distributed into two groups (n=15...

ABSTRACT Background Processed nerve allograft (PNA) is an alternative to autograft for the reconstruction of peripheral nerves. We hypothesize that repair with PNA in a military population will have low rate meaningful recovery (M ≥ 3) because frequency blasting mechanisms and large zones injury. Methods A retrospective review Registry Avance Nerve Graft Evaluating Utilization Outcomes Reconstr...

Using ideas of the Dowker duality we prove that Rips complex at scale $r$ is homotopy equivalent to nerve a cover consisting sets prescribed diameter. We then develop functorial version Nerve theorem coupled with duality, which presented as Functorial Dowker-Nerve Diagram. These results are incorporated into systematic theory filtrations arising from covers. As result provide general framework ...

BACKGROUND From January 1981 through March 1996, 20 patients with head and neck cancer underwent radical neck dissection with sacrifice of the spinal accessory nerve and immediate reconstruction of the nerve using a microsurgical technique and a cable graft of the great auricular nerve. METHODS Postoperative shoulder function was assessed via a subjective questionnaire, objective strength tes...
