Digit Tip Regeneration: Merging Regeneration Biology with Regenerative Medicine.

Stem Cells Transl Med 2018 Mar 5;7(3):262-270. Epub 2018 Feb 5.

Department of Veterinary Physiology & Pharmacology, College of Veterinary Medicine & Biomedical Sciences, Texas A&M University, College Station, Texas, USA.

Regeneration Biology is the study of organisms with endogenous regenerative abilities, whereas Regenerative Medicine focuses on engineering solutions for human injuries that do not regenerate. While the two fields are fundamentally different in their approach, there is an obvious interface involving mammalian regeneration models. The fingertip is the only part of the human limb that is regeneration-competent and the regenerating mouse digit tip has emerged as a model to study a clinically relevant regenerative response.

Use of an Intra-Arterial Catheter as a Provisional Conduit for Regulated Outflow Management in the Setting of Artery-Only Digital Replantation.

J Hand Microsurg 2017 Dec 27;9(3):163-166. Epub 2017 Nov 27.

Curtis National Hand Center, MedStar Union Memorial Hospital, Baltimore, Maryland, Unites States.

Successful replantation of distal digital segments necessitates the establishment of sufficient outflow to minimize congestion and progressive tissue necrosis. In cases where only arterial anastomosis is feasible, an artificial outlet must be provided to maintain physiological requirements until microvenous circulation regenerates. This can be accomplished using any number of "exsanguination techniques" designed to facilitate egress through ongoing passive blood loss. Read More

From the *IST-EL Microsurgery and Rehabilitation Group; and †Department of Plastic and Reconstructive Surgery, Goztepe Training and Research Hospital, T.C. Medeniyet University, Istanbul, Turkey.

The number of venous anastomoses performed during fingertip replantation is one of the most important factors affecting the success of replantation. However, because vessel diameters decrease in the zone 1 level, vessel anastomoses, especially vein anastomoses, are technically difficult and, thus, cannot be performed in most cases. Alternative venous drainage methods are crucial when any reliable vein repair is not possible. Read More

Simple EMG-driven musculoskeletal model enables consistent control performance during path tracing tasks.

Conf Proc IEEE Eng Med Biol Soc 2016 08;2016:1-4

Consistent, robust performance is critical for the utility and user-acceptance of neurally-controlled powered upper limb prostheses. We preliminarily evaluated the performance consistency of an electromyography (EMG)-driven controller based on a two degree-of-freedom musculoskeletal hand model, whose simplified structure is more practical for real-time prosthesis control than existing, complex models. Parameters of four virtual muscles were computed by numerical optimization from an able-bodied subject's kinematic and EMG data collected during wrist and metacarpophalangeal (MCP) flexion/extension movements.

Objective: We investigated the feasibility of a novel, customizable, simplified EMG-driven musculoskeletal model for estimating coordinated hand and wrist motions during a real-time path tracing task.

Approach: A two-degree-of-freedom computational musculoskeletal model was implemented for real-time EMG-driven control of a stick figure hand displayed on a computer screen. After 5-10 minutes of undirected practice, subjects were given three attempts to trace 10 straight paths, one at a time, with the fingertip of the virtual hand. Read More

Distal phalanx amputation with delayed presentation and successful reconstruction with reposition and flap after 2 weeks.

Indian J Plast Surg 2016 Sep-Dec;49(3):419-421

Hospital Sao Lucas, Pontifical Catholic University of Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, Brazil.

Traumatic finger amputations are common, causing significant functional and cosmetic deficits. Microsurgical replantation techniques are the mainstay of treatment for most such injuries although they require adequate conservation of the amputated segment for a successful result. In distal finger amputations, replantation is the procedure of choice, as long as the amputated fragment is viable. Read More

Fingertip Replantation With Palmar Venous Anastomoses in Children.

Ann Plast Surg 2017 Jun;78(6):692-696

From the Department of Orthopedic Surgery, Shanghai Jiao Tong University Affiliated Sixth People's Hospital, Shanghai, PR China.

Background: Fingertip amputation in children is difficult to manage using microsurgical replantation techniques and many salvage procedures have failed owing to the nonavailability of suitable veins for anastomosis in the fingertip. This study reviewed our experience of pediatric fingertip replantation involving palmar venous anastomoses and evaluated the clinical outcomes.

Methods: From October 2008 to May 2013, 21 pediatric fingertips that had been completely amputated at or distal to the distal interphalangeal joint of the finger, or at or distal to the interphalangeal joint of the thumb were managed using complete replantation. Read More

J Hand Surg Am 2017 Feb 10;42(2):e119-e123. Epub 2016 Dec 10.

Division of Plastic Surgery, Vancouver General Hospital, University of British Columbia, Vancouver, Canada.

The literature generally supports the safety of epinephrine injection in the digits, but recent case reports describe ischemic adverse events associated with the use of lidocaine and epinephrine in which phentolamine rescue was not performed. We present a case of finger necrosis and subsequent amputation in a patient after 1% lidocaine with 1:100,000 epinephrine was injected in the fat and flexor sheaths in the palm for a 3-finger trigger release. Phentolamine rescue was not performed. Read More

Ned Tijdschr Geneeskd 2016;160:D192

Canisius-Wilhelmina Ziekenhuis, afd. Plastische Chirurgie, Nijmegen.

Infections of the hand can result in significant limitation of the function of the hand, and may even require partial amputation of a digit. A felon is an abscess of the distal pulp of the fingertip, which can spread rapidly through the flexor tendon sheath when not treated appropriately. Knowledge of the anatomy and the correct method of physical examination are essential when assessing a patient suspected of having a felon or flexor tendon sheath infection. Read More

Does Graft on Flap Method Work on Sequela of Fingertip Amputation?

J Hand Surg Asian Pac Vol 2016 10;21(3):428-31

1 Department of Orthopaedic Surgery, Dokkyo Medical University Koshigaya Hospital, Saitama, Japan.

The graft on flap method, a useful option for the restoration of fresh fingertip amputation, was applied to the reconstruction of the short fingertip stumps resulting from the initial amputated stump plasties. As a modification, a nail bed graft from the big toe and a small cubic iliac bone graft were substituted for the lost tissues normally reduced as a composite graft in fresh cases. Upon follow-up ranging from 1 to 8 years, the grafted bone was found to have been resorpted in all cases. Read More

Double V-Y Flap to Cover the Fingertip Injury: New Technique and Cases.

Tech Hand Up Extrem Surg 2016 Dec;20(4):133-136

*Asotrauma Clinic, Ibagué †Orthopedics and Traumatology Unit, Faculty of Medicine, National University of Colombia, Bogotá, Colombia.

The volar V-Y flap is used in transverse or dorsal oblique amputations in fingertip injuries; however, its use is contraindicated in patients with volar oblique amputations and cannot advance distally enough to cover the defect. The aim of this report is to describe a technique of double V-Y flap to cover fingertip defects in which a simple V-Y flap is not enough. This technique allows advancement between 30% and 50% farther than the original, simple V-Y flap. Read More
