Limb-sparing sarcoma reconstruction with functional composite thigh flaps.

INTRODUCTION: Innervated muscle transfer can improve functional outcomes after extensive limb-sparing sarcoma resections. We report our experience using composite thigh flaps for functional reconstruction of large oncologic extremity defects. PATIENTS AND METHODS: Between 2011 and 2014, four limb-sparing oncologic resections (3 lower extremities, 1 upper extremity) underwent immediate functional reconstruction with composite thigh free flaps in three males and one female. The age of the patients ranged from 36 to 73 years. There were 3 soft-tissue sarcomas and one giant cell tumor, all required resection of entire muscle compartments. Flap components included fasciocutaneous tissue with sensory nerve, plicated iliotibial band (ITB), and variable amounts of motorized vastus lateralis (VL). RESULTS: All flaps survived without complications. All patients showed VL motor innervation by six months. Follow-up ranged from 20 to 36 months. Motor strength ranged from 2 to 5 out of 5, active range of motion was 25-92% of normal, and Musculoskeletal Tumor Society (MSTS) Scores were between 22 and 29 out of 30. CONCLUSIONS: Limb-sparing techniques for upper and lower extremity sarcomas continue to evolve. Our experience has validated the composite thigh free flap as an excellent option for one-stage functional reconstruction of large limb defects.

Dual venous outflow improves lower extremity trauma free flap reconstructions.

BACKGROUND: Venous outflow problems are the most common reasons for perioperative flap complications. The benefit of a second venous anastomosis, however, remains unclear in lower extremity trauma free flap reconstruction and warrants further investigation. MATERIALS AND METHODS: Retrospective review of our institutional flap registry from 1979 to 2014 identified 464 free flaps performed for lower leg trauma reconstruction. Patient demographics, flap characteristics, and outcomes were examined. RESULTS: A total of 219 flaps were randomly selected for preliminary analysis. Single-vein outflow was more common (72.6%) than dual-vein (27.4%); most of the recipients were in deep venous system (83.6%) versus superficial (11.9%) or both (4.6%). Two-vein anastomoses were more likely in fasciocutaneous flaps than muscle flaps (P = 0.001) and in smaller (<300 cm(2)) flaps (P = 0.002). Complications occurred in 98 flaps (44.7%); with 54 partial flap losses (24.7%), and 11 complete flap losses (5.0%). Multivariable regression analysis controlling for age, sex, flap type, presence of bone gap, flap size, vein size mismatch, and time since injury demonstrated dual-vein outflow to be protective against complications (relative risk [RR] = 0.269, P = 0.001), partial flap failure (RR = 0.351, P = 0.031), and any flap failure (RR = 0.31, P = 0.010). No significant difference in operative time was found (P = 0.664). CONCLUSIONS: Dual-vein outflow demonstrated 73% reduction in overall complications and 69% reduction in flap failure rate compared to single-vein flaps. These results suggest a protective effect of a dual-vein outflow system, and when considered together with our findings of unchanged operative time, provide evidence for preferential use of two venous anastomoses when possible for free flap reconstruction of lower extremity trauma.

Creating the Perfect Umbilicus: A Systematic Review of Recent Literature.

BACKGROUND: The aim of this study was to perform an updated systematic review of the literature over the last 10 years, analyzing and comparing the many published techniques with the hope of providing plastic surgeons with a new standard in creating the perfect umbilicus in the setting of both abdominoplasty and abdominally based free-flap breast reconstruction. METHODS: An initial search using the PubMed online database with the keyword "umbilicoplasty" was performed. These results were filtered to only include articles published within the last 10 years. The remaining articles were thoroughly reviewed by the authors and only those pertaining to techniques for umbilicoplasty in the setting of abdominoplasty and abdominally based free flap were included. RESULTS: Of the 10 unique techniques yielded by our search, 9/10 (90 %) initially incised the native umbilicus with a round, oval, or vertical ellipse pattern. Of the 9 techniques that initially perform a round incision, 4 of them (44.4 %) later modify the round umbilicus with either an inferior or superior excision to create either a "U"- or "inverted U"-shaped umbilicus. In terms of the shape of the incision made in the abdominal flap for umbilical reinsertion, the most common were either a round incision or an inverted "V" or "U," both of which accounted for 4/10 (40 %) and 3/10 (30 %), respectively. Almost all of the studies (8/10; 80 %) describe "defatting" or trimming of the subcutaneous adipose tissue around the incision to create a periumbilical concavity following inset of the umbilicus. 4/10 (40 %) of the techniques describe suturing the dermis of the umbilical skin to rectus fascia. Furthermore, 3/10 (30 %) advise that stalk plication is a necessary step to their technique. 7/9 techniques (77.8 %) preferred nondissolvable sutures for skin closure, with nylon being the most common suture material used. Only 2/9 (22.2 %) used dissolvable sutures. CONCLUSION: Although future studies are necessary, it is our hope that this systematic review better elucidates the techniques and provides some guidance to both aesthetic and reconstructive plastic surgeons in the pursuit of creating the perfect umbilicus following abdominoplasty and TRAM/DIEP breast reconstruction.

Current practice among plastic surgeons of antibiotic prophylaxis and closed-suction drains in breast reconstruction: experience, evidence, and implications for postoperative care.

BACKGROUND: Despite their widespread use, there are no evidence-based guidelines on the management of closed-suction drains or antibiotics in postmastectomy breast reconstruction. The purpose of this study was to assess consensus and variation in postoperative care among plastic surgeons. METHODS: The authors designed and administered a self-reported, anonymous survey to 4669 American Society of Plastic Surgeons and Canadian Society of Plastic Surgeons members in October 2009. RESULTS: A total of 650 completed surveys were available for analysis. A majority (>81%) of respondents reported using closed-suction drains in breast reconstruction. Most surgeons (>93%) used a volume criteria for drain removal, most commonly when drain output was ≤30 mL over 24 hours (>86%). Preoperative antibiotic use was nearly universal (98%), usually consisting of intravenous cefazolin (97%). Postoperative care demonstrated less uniformity with outpatient antibiotics administered by 72% of respondents. Surgeons were divided on when to discontinue outpatient antibiotics: 46% preferred concomitant discontinuation with drains, whereas 52% preferred a specific postoperative day. No clear consensus was observed for the number (1 or 2) or type (Jackson-Pratt or Blake) of drains used. Respondents were further divided on the restriction of postoperative showering with drains and the use of acellular dermal matrix. CONCLUSIONS: These results demonstrate a consensus for drain use, drain removal, and preoperative antibiotic administration. There was no consensus for number or type of drain used, postoperative antibiotic use, shower restrictions, and use of acellular dermal matrix. Our results further emphasize the need for evidence-based postoperative-care guidelines specific to breast reconstruction.

Proximal Row Carpectomy versus Four-Corner Arthrodesis for the Treatment of Scapholunate Advanced Collapse/Scaphoid Nonunion Advanced Collapse Wrist: A Cost-Utility Analysis.

BACKGROUND: Two mainstay surgical options for salvage in scapholunate advanced collapse and scaphoid nonunion advanced collapse are proximal row carpectomy and four-corner arthrodesis. This study evaluates the cost-utility of proximal row carpectomy versus three methods of four-corner arthrodesis for the treatment of scapholunate advanced collapse/scaphoid nonunion advanced collapse wrist. METHODS: A cost-utility analysis was performed in accordance with the Second Panel on Cost-Effectiveness in Health and Medicine. A comprehensive literature review was performed to obtain the probability of potential complications. Costs were derived using both societal and health care sector perspectives. A visual analogue scale survey of expert hand surgeons estimated utilities. Overall cost, probabilities, and quality-adjusted life-years were used to complete a decision tree analysis. Both deterministic and probabilistic sensitivity analyses were performed. RESULTS: Forty studies yielding 1730 scapholunate advanced collapse/scaphoid nonunion advanced collapse wrists were identified. Decision tree analysis determined that both four-corner arthrodesis with screw fixation and proximal row carpectomy were cost-effective options, but four-corner arthrodesis with screw was the optimal treatment strategy. Four-corner arthrodesis with Kirschner-wire fixation and four-corner arthrodesis with plate fixation were dominated (inferior) strategies and therefore not cost-effective. One-way sensitivity analysis demonstrated that when the quality-adjusted life-years for a successful four-corner arthrodesis with screw fixation are lower than 26.36, proximal row carpectomy becomes the optimal strategy. However, multivariate probabilistic sensitivity analysis confirmed the results of our model. CONCLUSIONS: Four-corner arthrodesis with screw fixation and proximal row carpectomy are both cost-effective treatment options for scapholunate advanced collapse/scaphoid nonunion advanced collapse wrist because of their lower complication profile and high efficacy, with four-corner arthrodesis with screw as the most cost-effective treatment. Four-corner arthrodesis with plate and Kirschner-wire fixation should be avoided from a cost-effectiveness standpoint.

Management of Unstable Distal Radius Fractures: A Survey of Hand Surgeons.

Background Length of immobilization after operative fixation of unstable distal radius fractures and management in elderly patients is an area of debate. Purpose The purpose of this study is to delineate common practices of fellowship-trained hand surgeons and how they compare with current evidence-based protocols. Methods Surveys were distributed to American Society for Surgery of the Hand members on preferred methods of fixation, postoperative immobilization, and variations in treatment of elderly patients with unstable distal radius fractures. Responses were analyzed in comparison to a literature review. Subgroups were compared with regard to training, practice type, and years in practice. Results Four-hundred eighty-five surveys were analyzed. Volar fixed-angle plating was the most common choice of fixation (84.7%). Patients are most often immobilized for 1 to 2 weeks (40.0%) with range of motion (ROM) therapy begun most commonly between 1 and 4 weeks (47.2%). The majority of surgeons do not treat fractures differently in patients more than 65 years old. Physicians with more than 20 years of experience were significantly more likely to begin wrist ROM sooner with volar plating versus other fixation techniques compared with physicians with less than 20 years of experience (40.7% vs. 34.2%, respectively). Also, physicians in academic-only practices were more likely to immobilize patients for a shorter time after volar plating compared with those in privademics. Conclusion Volar fixed-angle plating is the dominant fixation method for unstable distal radius fractures among fellowship-trained hand surgeons. Elderly patients are not treated more conservatively and rigid immobilization after operative fixation remains the treatment of choice despite current evidence-based protocols.

Preparation is the Only Shortcut You Need in Surgery: A Guide to Surgical Rehearsals for Hand and Upper Extremity Transplantation.

As upper extremity transplantation is becoming more accepted worldwide, the demand for a fresh tissue cadaveric training model for this procedure is increasing and necessary to assure surgical success. Surgical rehearsals can decrease operative time, improve technique, and reduce errors made on the actual day of surgery. The purpose of this article is to describe a method for surgical rehearsal of upper extremity transplantation using cadaveric specimens based on the clinical experience of an academic institution with an active transplantation program. The logistics of rehearsal setup, equipment, and modified version of procedural checklists are described.

Anatomic Locking Plate Fixation for Scaphoid Nonunion.

Nonunion can occur relatively frequently after scaphoid fracture and appears to be associated with severity of injury. There have been a number of techniques described for bone grafting with or without screw fixation to facilitate fracture healing. However, even with operative fixation of scaphoid fractures with bone grafting nonunion or malunion rates of 5 to 10 percent are still reported. This is the first report of an anatomic locking plate for scaphoid fracture repair in a 25-year-old right hand dominant healthy male.
