    Do two venous anastomoses decrease venous thrombosis during limb reconstruction?
    (2019) IAMAGUCHI, Raquel; BURGOS, Felipe; SILVA, Gustavo; CHO, Alvaro; NAKAMOTO, Hugo; TAKEMURA, Renan; WEI, Teng; REZENDE, Marcelo de; JR, Rames Mattar
    BACKGROUND: The optimal number of veins to be anastomosed in perforator flaps for limb reconstruction and its influence on the results remain controversial. Venous thrombosis of microvascular anastomoses is a commonly recorded complication in soft tissue reconstruction. OBJECTIVE: To evaluate the effect of two venous anastomoses in the incidence of venous thrombosis for limb reconstruction using anterolateral thigh (ALT) microsurgical free flaps. METHODS: This was a cross-sectional study on patients undergoing limb reconstruction using ALT flap during 2014-2017. Perioperative information was recorded and patients were divided in two groups: group 1 (one venous anastomosis; 17 patients) and group 2 (two venous anastomoses; 21 patients). Complications were investigated. RESULTS: Overall, 38 microsurgical flaps were included. The mean age was 33 years, and 32 patients were male. The most prevalent wounds were traumatic. Group 1 presented a higher complication rate than group 2 (47% vs. 24%; p = 0.065), although the difference was not significant. Group 1 presented a higher rate of venous anastomotic thrombosis (p = 0.032) than group 2. The overall success rate was 92%. CONCLUSION: For limb reconstruction using ALT microsurgical free flaps, two venous anastomoses are associated with a low rate of venous thrombosis in microvascular anastomoses.

    TREATMENT OF SCHAPHOID NONUNION WITH VOLAR LOCKED PLATE
    (2019) BURGOS, Felipe Hellmeister; NAKAMOTO, Joao Carlos; NAKAMOTO, Hugo Alberto; IWASE, Fernanda do Carmo; MATTAR JUNIOR, Rames
    Objective: To assess and compare radiographic, tomographic and functional pre and postoperative parameters of patients submitted to treatment of nonunion of the scaphoid waist with locked plate for scaphoid. Methods: This is a case series of scaphoid waist nonunion, operated from March 2017 to March 2018 at the Institute of Orthopedics and Traumatology of HCFMUSP, using the technique of Fisk-Fernandez and osteosynthesis with locked plate for scaphoid APTUS (R) Hand from Medartis. The patients were submitted to radiographs, computed tomography and functional evaluation by the occupational therapy team in the pre and postoperative periods. Results: There was consolidation of the scaphoid waist nonunion in all cases, improvement in the parameters of carpal alignment in the imaging examinations, but functionally we observed reduction of the range of motion and grip strength in relation to the contralateral limb. Conclusions: The treatment of the scaphoid waist nonunion with locked plate was effective, with a high index of consolidation and improvement of the carpal alignment in the imaging tests, although with a reduction in the range of motion and grip strength in relation to the contralateral limb when evaluated with 12 weeks postoperatively.
