Sensory nerve trauma at the level of the wrist can lead to debilitating neuromas. Targeted muscle reinnervation (TMR) is an effective therapy for the treatment of neuromas. Here we propose the use of the terminal anterior interosseous nerve (AIN) as a viable recipient for TMR. All superficial sensory nerves around the wrist, including the dorsal ulnar sensory nerve, the distal lateral antebrachial cutaneous nerve, the distal branches of the superficial branch of the radial nerve, and the palmar cutaneous branch of the median nerve were dissected in 2 cadaver specimens. The AIN branch to pronator quadratus was divided just distal to the final branch of flexor pollicis longus to preserve adequate length for TMR. The sensory nerves at the wrist were fully dissected to identify a viable location for coaptation to the AIN. After the cadaveric concept was demonstrated, the technique was successfully used in a clinical case. In summary, the distal AIN is a versatile recipient for TMR as a treatment of painful sensory neuromas at the level of the wrist, with minimal donor-site morbidity.

The nationwide focus on patient safety and the health of residents has increased the demand for educational tools outside the operating room. Simulation is a valuable tool for assessing and developing surgical skills in a controlled and safe environment. The use of simulation as a formal component of training has been increasing in various surgical subspecialties. In general surgery, simulation examinations such as the Fundamentals of Laparoscopic Surgery and Fundamentals of Endoscopic Surgery have become a prerequisite to board certification. Although formal simulation examinations in plastic surgery are not universal, there has been an increase in the use of simulation to increase resident competency in the operating room. For now, we will review the current state of simulation in craniofacial, hand, microvascular, and esthetic surgery and discuss applications for the future. We will also discuss the evolving role of artificial intelligence, virtual reality, and augmented reality in plastic surgery training and testing.

Pluripotent stem cells can help recreate a variety of different tissues. Stem cells are already in use in a variety of ways in the medical field but plastic surgeons have particular interest because of the constant need to produce additional tissue or mold existing tissue. More and more commercial products are being marketed with far-reaching goals and some with proven and promising results. In this article, the authors discuss the basic science behind stem cells and the theories on how they work. They then discuss some active uses of stem cells that should be understood by all plastic surgeons. The reader should then have an understanding and basis to evaluate new technologies and commercial products as they develop.

Arthritis remains a widespread and yet unsolved therapeutic dilemma. Cartilage grafting has proven to be difficult and satisfactory results are often elusive. There are several inherent difficulties. These include both chondrocyte migration and the lack of sufficient uptake of nutrients to allow for graft survival. With autografts, there is also the paucity of symptom-free donor sites. Accordingly, multiple alternative therapies for cartilage regeneration and/or substitution have been developed over time. In this article, the authors shall discuss the options for the treatment of damaged cartilage with a focus on the cartilage grafting techniques.

BACKGROUND: Maintaining optimal coagulation is vital for successful microvascular tissue transfer. The viscoelastic thromboelastography (TEG) is a modern and dynamic method to assess a patient's coagulation status. The aim of this study was to evaluate its diagnostic capabilities of identifying microvascular complications. METHODS: A retrospective chart review was conducted for the most recent 100 cases of abdominal free flap breast reconstruction of a single surgeon. Patient demographics, medical history, clinical, and operative details were documented. Thrombocyte counts, prothrombin time (PT), activated partial thromboplastin time (aPTT), and various TEG parameters were gathered for preoperative, intraoperative, and two postoperative time points. RESULTS: = 0.049), while PT and aPTT failed to identify these patients. Of those, two resulted in flap loss (1.2%) that both occurred in patients with abdominal scars from previous surgery. CONCLUSION/CONCLUSIONS: The TEG is a useful adjunct for monitoring coagulation status in microsurgical breast reconstruction. When thrombosis at the anastomosis occurs, TEG correlates with a more rapid rebound from an intraoperative hypocoagulable state to a postoperative hypercoagulable state, when using the TEG. The TEG is a valuable tool for a more dynamic assessment of the patients' changing coagulation status.

Introduction: /UNASSIGNED:Gallstones are an etiological factor in 23%-54% of patients with acute pancreatitis. A small proportion of these patients will also have intestinal complications requiring necrosectomy with diverting loop ileostomy. Later, these patients require cholecystectomy and ileostomy reversal. Laparoscopic cholecystectomy is fraught with difficulty in these patients due to dense intra-abdominal adhesions, and many surgeons resort to an open approach. We describe a technique which takes advantage of the ileostomy site for initial access. Materials and Surgical Technique/UNASSIGNED:port. Additional ports are inserted and standard steps are followed for cholecystectomy. Conclusion/UNASSIGNED:port.
