The respective roles of plastic and orthopedic surgery in limb salvage

Lerman, Oren Z; Kovach, Stephen J; Levin, L Scott
The evolution of techniques in plastic surgery and orthopedic surgery over the past few decades has enabled a great level of success in limb salvage. Limb salvage can now be achieved when faced with trauma, tumor, sepsis, or vascular disease. In fact, 'What can be salvaged?' is now a less common debate among clinicians than 'What should be salvaged?' Often discussions among surgeons from various subspecialties, including orthopedics, plastics, trauma, and vascular surgery, are characterized by how each of them can perform their respective part of the salvage operation, be it bony fixation, revascularization, or soft-tissue coverage, but none of them is certain whether it should be attempted. What is needed in these clinical situations is an interdisciplinary team approach led by individual or groups of clinicians who are familiar not only with their own subspecialized skills but also with those of their colleagues and the outcomes associated with integrated efforts at limb salvage. The concept of orthoplastic surgery is based on such an idea, where the combined skills and techniques of the orthopedic surgeon and reconstructive microsurgeon are used in concert to direct efforts toward limb salvage or decide against it when it is not indicated. This article presents a review of the roles of the two subspecialties and how an orthoplastic team can function with the current techniques to improve outcomes in limb salvage surgery

Microsurgery of the upper extremity

Lerman, Oren Z; Haddock, Nicholas; Elliott, River M; Foroohar, Abtin; Levin, L Scott
In the past 50 years, hand surgeons have made considerable contributions to microsurgery. The unique demands of complex upper extremity care have driven many of the technical and scientific advances of this discipline, including functional muscle transfers, nerve transfers, and composite tissue allotransplantation. The purpose of this article was to review the current applications of microsurgery to the upper extremity

Perforator flap breast reconstruction after unsatisfactory implant reconstruction

Levine, Steven M; Lester, Mary E; Fontenot, Benjamin; Allen, Robert J Sr
In 2009, 86,424 breast reconstructions were performed in the United States, with 76% being implant-based procedures. Capsular contracture and infection are the 2 most cited indications for implant explantation, resulting in a reconstruction failure. However, several patients are dissatisfied with implant reconstruction even without the aforementioned complications. We hypothesize that microvascular autologous tissue transfer with perforator free-flap breast reconstruction provides an excellent salvage modality in the face of an unsatisfactory implant reconstruction, resulting in an improved cosmetic and functional outcome, with low risk of complications. We retrospectively reviewed the charts of patients in the senior author's practice who underwent perforator flap breast reconstruction between the years 1998 through 2008, and identified all patients who had prior implant reconstruction. Indications for implant explantation, medical history, operative procedure, and postoperative complications were reviewed. During the study period, 1846 perforator flaps were performed. We found 191 patients who underwent autologous breast reconstruction after implant reconstruction with a total of 284 flaps (15.4%). The most frequent patient complaint was unnatural appearance and feel of the implants (Baker I or Baker II), and the majority of patients had not undergone radiation. Most patients were reconstructed using abdominal flaps with 164 deep inferior epigastric perforators, 50 superior gluteal artery perforators, 30 superficial inferior epigastric arteries, 35 inferior gluteal artery perforators, and 5 transverse upper gracilis. The total complication rate was 7.4%, with most complications related to wound healing at the donor site. There were 3 flap losses (1%), all of which were later successfully reconstructed with another perforator flap. Implant failures are traditionally thought to be in patients with Baker grade III/IV capsular contractures and in patients status post radiation therapy. However, in our study, the majority of patients seeking perforator flap reconstruction after implant reconstruction complained of an unnatural feel and appearance of their breasts, and did not have a severe capsular contracture deformity (Baker III/IV), nor had they undergone radiation. This suggests that implant reconstruction can lead to patient dissatisfaction severe enough to warrant removal even with Baker I/II results, and not in the setting of postradiation changes

Facial transplantation: avatars

Stricker, M; Simon, E; Angrigiani, C; Perroni, C
Avatar carries a pejorative connotation often related to an unfortunate hazard. In face transplants, incarnations were numerous. The analysis of their evolution through time and increasing sophistication of procedures turn out to be informative regarding the wide disrepairs in the craniofacial area. The authors report the principal constraints of face transplant and the evolution in minds to deal with it

Deep-plane angle rotation flap for reconstruction of perioral lesions

Haddock, Nicholas T; Zide, Barry M
INTRODUCTION: : A cervicofacial flap remains the principal method to close defects of the posterior cheek. Schrudde described a variant of this technique, termed the angle-rotation flap, which allowed primary closure of the donor site. This flap has been elevated in the deep plane for the more medial defects. We extend this technique for upper lip reconstruction. METHODS: : Two cases were reviewed that underwent upper lip reconstruction with the deep-plane Schrudde flap. RESULTS: : Two cases are presented to describe the use of the deep-plane angle-rotation flap. The first patient sustained a burn to his upper lip and the second patient had a partially grafted defect following a Mohs excision. DISCUSSION: : In patients with insignificant nasolabial folds, the deep-plane Schrudde flap is a good option to reconstruct perioral defects. The utilization of the deep plane improves the blood supply and allows improved contour for reconstruction of deeper defects

Surface characterization of Ti and Y-TZP following non-thermal plasma exposure. L

R F A Silva N; Coelho PG; Valverde GB; Becker K; Ihrke R; Quade A; Thompson VP
Novel non-thermal plasma (NTP) technology has the potential to address the bonding issues of Y-TZP and Ti surfaces. This study aims to chemically characterize and evaluate the surface energy (SE) of Y-TZP and Ti surfaces after NTP application. Y-TZP and Ti discs were treated with a hand-held NTP device followed by SE evaluation. Spectra of Y-TZP 3d and Ti 2p regions, survey scans, and quantification of the elements were performed via X-ray photoelectron Spectroscopy (XPS) prior and after NTP. Separate Y-TZP and Ti discs were NTP treated for contact angle readings using (10-methacryloyloxydecyl dihydrogenphosphate) MDP primer. Significant augmentation of SE values was observed in all NTP treated groups. XPS detected a large increase in the O element fraction on both Y-TZP and Ti surfaces. Reduction of contact angle reading was obtained when the MDP primer was placed on NTP treated Y-TZP. Ti surface showed high SE before and after NTP application on Ti surfaces. NTP decreased C and increased O on both surfaces independently of application protocol. Wettability of MDP primer on Y-TZP was significantly increased after NTP. The high polarity obtained on Y-TZP and Ti surfaces after NTP applications appear promising to enhance bonds. (c) 2011 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2011

Modified Y-TZP core design improves all-ceramic crown reliability

Silva, N R F A; Bonfante, E A; Rafferty, B T; Zavanelli, R A; Rekow, E D; Thompson, V P; Coelho, P G
This study tested the hypothesis that all-ceramic core-veneer system crown reliability is improved by modification of the core design. We modeled a tooth preparation by reducing the height of proximal walls by 1.5 mm and the occlusal surface by 2.0 mm. The CAD-based tooth preparation was replicated and positioned in a dental articulator for core and veneer fabrication. Standard (0.5 mm uniform thickness) and modified (2.5 mm height lingual and proximal cervical areas) core designs were produced, followed by the application of veneer porcelain for a total thickness of 1.5 mm. The crowns were cemented to 30-day-aged composite dies and were either single-load-to-failure or step-stress-accelerated fatigue-tested. Use of level probability plots showed significantly higher reliability for the modified core design group. The fatigue fracture modes were veneer chipping not exposing the core for the standard group, and exposing the veneer core interface for the modified group

Comparative reliability analyses of zirconium oxide and lithium disilicate restorations in vitro and in vivo

Silva, Nelson R F A; Thompson, Van P; Valverde, Guiherme Bonecker; Coelho, Paulo G; Powers, John M; Farah, John W; Esquivel-Upshaw, Josephine
BACKGROUND: The authors analyzed the in vitro and in vivo performance of lithium disilicate glass-ceramic (LDGC) restorations and yttria-stabilized tetragonal zirconia polycrystalline (Y-TZP) (that is, zirconium oxide) restorations with regard to reliability, clinical performance and abrasion resistance. METHODS: In the in vitro study, four authors subjected samples of LDGC, Y-TZP and metal-ceramic crowns to step-stress fatigue testing. Four investigators assessed the in vivo clinical performance of LDGC and zirconium oxide-based restorations at four and seven years, respectively. In addition, one author conducted a randomized, controlled clinical trial to analyze the volumetric loss of enamel and ceramic antagonist surfaces. RESULTS: The LDGC crowns exhibited the highest fatigue load-to-failure values in the in vitro analysis. The results of the in vivo assessment showed that the clinical performance of the LDGC restorations at four years was comparable to that of the zirconium oxide-based crowns at seven years. The results of the in vivo, randomized, controlled clinical trial showed that LDGC crowns were not only resistant to wear, but also were wear friendly to enamel antagonist surfaces. CONCLUSIONS: The LDGC crowns in the in vitro and in vivo studies exhibited high durability, and they were wear friendly to opposing natural dentition. CLINICAL IMPLICATIONS: LDGC and zirconium oxide-based crowns are a clinically acceptable means of treating teeth that require full-coverage restorations. In addition, LDGC materials exhibit excellent clinical performance, as well as demonstrate acceptable abrasion compatibility with the opposing natural dentition
