    Tratamento das fraturas do terço distal do rádio pela fixação externa e enxerto ósseo
    (Sociedade Brasileira de Ortopedia e Traumatologia, 2005-01-01) Angelini, Luiz Carlos; Albertoni, Walter Manna [UNIFESP]; Faloppa, Flávio [UNIFESP]; Universidade Metropolitana de Santos; Universidade Federal de São Paulo (UNIFESP)
    The author presents a prospective study in which he uses the external fixation method associated with the autogenous bone graft for the management of articular and metacarpal distal radius fractures. Thirty-six patients with a mean age of 52,2 years were treated. The follow-up had na average duration of 36,2 months. The stability of the reduction and its maintenance were assured by the external fixation with the autogenous bone graft. In the patients who underwent a densitometric analysis of the bone mass, the presence of the autogenous mass showed statistically steady in the long run. With this technique the rehabilitation could be antecipated had began in the immediate postoperative period, thas favoring the mobilization. In the fourth week the external fixation device is removed, this restoring the free movement of the wrist, except for the extension which is hampered by an splint of dorsal situation for two additional weeks. In the review of the data resulting from the treatment the anatomical and functional features were considered. The anatomical findings were obtained from radiographic examinations on the patients. The analysis of these outcomes were based on the Scheck method (1962) and were graded excellent in 72% of the cases, and good in 28%, satisfactory as a whole. The data related to the function obtained were evaluated based on the Green And O'Brien system (1978) modified by Cooney et al.(1987). In the 24th week, 14% were considered insatisfactory and 86% satisfactory. At 12 months and in december,1999, they were considere satisfactory as a whole. The complications detected during the treatment were: pine site infections in 8,31% of the cases, and transient symptoms of post-traumatic sympathetic dystrophy in 8,33%, all of them thoroughly resolved with appropriate therapy. In 33% of the patients there were also identified signs of post-traumatic arthristis of the ulnal styloid process which however evolved asymptomatically in all cases under review.

    Treatment of reducible unstable fractures of the distal radius: randomized clinical study comparing the locked volar plate and external fixator methods: study protocol
    (Biomed Central Ltd, 2014-03-05) Raduan Neto, Jorge [UNIFESP]; Moraes, Vinicius Ynoe de [UNIFESP]; Santos, João Baptista Gomes dos [UNIFESP]; Faloppa, Flávio [UNIFESP]; Belloti, João Carlos [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Hand Arm & Shoulder Surg Unit
    Background: Various treatments are available for reducible unstable fractures of the distal radius, such as closed reduction combined with fixation by external fixator (EF), and rigid internal fixation using a locked volar plate (VP). Although there are studies comparing these methods, there is no conclusive evidence indicating which treatment is best. the hypothesis of this study is that surgical treatment with a VP is more effective than EF from the standpoint of functional outcome (patient-reported).Methods/Design: the study is randomized clinical trial with parallel groups and a blinded evaluator and involves the surgical interventions EF and VP. Patients will be randomly assigned (assignment ratio 1: 1) using sealed opaque envelopes. This trial will include consecutive adult patients with an acute (up to 15 days) displaced, unstable fracture of the distal end of the radius of type A2, A3, C1, C2 or C3 by the Arbeitsgemeinschaft fur Osteosynthesefragen-Association for the Study of Internal Fixation classification and type II or type III by the IDEAL(32) classification, without previous surgical treatments of the wrist. the surgical intervention assigned will be performed by three surgical specialists familiar with the techniques described. Evaluations will be performed at 2, and 8 weeks, 3, 6 and 12 months, with the primary outcomes being measured by the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and measurement of pain (Visual Analog Pain Scale and digital algometer). Secondary outcomes will include radiographic parameters, objective functional evaluation (goniometry and dynamometry), and the rate of complications and method failure according to the intention-to-treat principle. Final postoperative evaluations (6 and 12 months) will be performed by independent blinded evaluators. for the Student's t-test, a difference of 10 points in the DASH score, with a 95% confidence interval, a statistical power of 80%, and 20% sampling error results in 36 patients per group.Discussion: Results from this study protocol will improve the current evidence regarding to the surgical treatment these fractures.
