Financial impact of hand surgery programs on academic medical centers.
This study analyzes the financial performance of hand surgery in the Department of Surgery at the University of Michigan. This analysis can serve as a reference for other medical centers in the financial evaluation of a hand surgery program. ⋯ While contributing to the academic mission of the institution, hand surgery is financially rewarding for the Department of Surgery. In addition, hand surgery activity contributes substantially to the financial well-being of the academic medical center.

Randomized Controlled Trial
Randomized clinical study to compare the accuracy of navigated and non-navigated thoracic pedicle screws in deformity correction surgeries.
Randomized clinical trial (level I evidence). ⋯ Iso-C navigation increases accuracy, and reduces surgical time and radiation in thoracic deformity correction surgeries.

Multicenter Study
A cohort study of acute plastic surgery trauma and burn referrals using telemedicine.
A store-and-forward telemedicine system was used to supplement normal telephone referrals to the plastic surgery unit at the Queen Victoria Hospital (QVH). During a 12-week prospective study, 11 units (8 hospitals and 3 minor injury units) with the telemedicine system and 10 units (8 hospitals and 2 minor injury units) without it regularly made referrals (at least 10) to the QVH. There were 389 referrals from the telemedicine-equipped units and 607 telephone referrals from the non-telemedicine units. ⋯ There was a significant difference in the management of patients when the telemedicine system was available, with more patients booked directly into day surgery and fewer attending for assessment. The burns unit and the day surgery unit demonstrated a significantly improved accuracy of triage. Telemedicine could have a valuable role to play in the triage and planning of acute plastic surgery referrals.

Clinical TrialA system for analyzing intraoperative B-Mode ultrasound scans of the liver.
In this article, a system for automatic analysis of intraoperative B-Mode ultrasound images of the liver is presented. The system is part of an assistance system for open liver surgery. ⋯ With this segmentation results, an ultrasound based 3D-model of the vascular structure is extracted and manually registered to a preoperative CT-based model. Anatomical landmarks like bifurcations of vessels are automatically extracted in the ultrasound-based model and will be used for an automatic registration process in further developments.

Laparoscopic radiofrequency ablation (RFA) is a safe and effective method for tumor destruction in patients with unresectable liver tumors. However, accurate probe placement using laparoscopic ultrasound guidance is required to achieve complete tumor ablation. After evaluation of an ultrasound navigation system for transcutaneous and open RFA, we now intend to transfer this technique to laparoscopic liver surgery. This study aimed to evaluate an electromagnetic navigation system for laparoscopic interventions using a perfusable ex vivo artificial tumor model. ⋯ Laparoscopic RFA requires advanced laparoscopic ultrasound skills for accurate placement of the RFA probe. The use of an ultrasound-based, laparoscopic online navigation system offers the possibility of out-of-plane needle placement and could increase the safety and accuracy of punctures. The perfused artificial tumor model presented a realistic model for the evaluation of this new technique.
