Abstract

Summary:. Microsurgery is a complex subspecialty requiring fine manual dexterity and a thorough understanding of microsurgical techniques, requiring years of training to reach proficiency. On a global scale, trainees may not have access to a longitudinal microsurgery curriculum and instead attend brief courses to learn microsurgical techniques, limiting their ability to practice the nuances of microsurgery. There remains a gap in global microsurgical education for trainees to have consistent educational exposure. This article presents a novel and easy to use software-based microsurgical system for virtual microsurgical teaching. In doing so, this system provides a free-of-cost and highly accessible avenue to deliver consistent microsurgical education worldwide.

Abstract

Background:. Despite significant improvements in zone II flexor tendon repair over the last 2 decades, function-limiting complications persist. This article describes 2 novel repair techniques utilizing flexor digitorum superficialis (FDS) autografts to buttress the flexor digitorum profundus (FDP) repair site without the use of core sutures. The hypothesis being that the reclaimed FDS tendon autograft will redistribute tensile forces away from the FDP repair site, increasing overall strength and resistance to gapping in Zone II flexor tendon injuries compared with the current clinical techniques. Methods:. Two novel FDP repair methods utilizing portions of FDS have been described: (1) asymmetric repair (AR), and (2) circumferential repair. Ultimate tensile strength and cyclical testing were used to compare novel techniques to current clinical standard repairs: 2-strand (2-St), 4-strand (4-St), and 6-strand (6-St) methods. All repairs were performed in cadaveric sheep tendons (n = 10/group), by a single surgeon. Results:. AR and circumferential repair techniques demonstrated comparable ultimate tensile strength to 6-St repairs, with all 3 of these techniques able to tolerate significantly stronger loads than the 2-St and 4-St repairs (P < 0.0001). Cyclical testing demonstrated that AR and circumferential repair were able to withstand a significantly higher total cumulative force (P < 0.001 and P = 0.0064, respectively) than the 6-St, while only AR tolerated a significantly greater force to 2-mm gap formation (P = 0.042) than the 6-St repair. Conclusion:. Incorporating FDS as an autologous graft for FDP repair provides at least a comparable ultimate tensile strength and a significantly greater cumulative force to failure and 2-mm gap formation than a traditional 6-St repair.

Abstract

Supplemental Digital Content is available in the text., Background: Liposuction is the treatment of choice for solid predominant extremity lymphedema. The classic lymphedema liposuction technique does not remove skin excess created following bulk removal. The skin excess is presumed to resolve with spontaneous skin contracture. We investigated the technique of simultaneously performing liposuction with immediate skin excision in patients with solid predominant lymphedema and compared the outcome with that from the classic technique. Methods: Modified liposuction with skin excision (mLIPO) and standard liposuction without skin excision (sLIPO) were offered to patients with solid predominant extremity lymphedema. Skin traction of 4 cm and undulating skin mobility constituted positive “flying squirrel” sign. Patients with negative “flying squirrel” sign were excluded. mLIPO patients underwent skin excision. Surgical outcomes and postoperative complications were compared. Results: The study enrolled 15 and 26 patients into the sLIPO and mLIPO groups, respectively. mLIPO patients demonstrated statistically significant decrease in seroma/hematoma, contour irregularity, and skin necrosis, while experiencing increased procedural satisfaction. Conclusions: Skin excision following liposuction for solid predominant lymphedema is safe. It decreases postoperative complication and improves surgical outcome.
