Objective: Although our knowledge of bone reconstruction through microsurgery has increased, the vascularized fibula flap remains one of the most difficult free flap reconstructions to perform, and complications remain a challenge. The incidence of obesity is increasing and is associated with higher rates of free flap complications, which can lead...
Article
ABSTRACT 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 inc...

Introduction: Indication of free tissue transfer for limb reconstruction continues to grow, and despite the good results with this treatment option, complications can impair the functional results and cause a raise in health costs, with prolonged hospitalization. Therefore, peri-operative surgical information and comorbidities were described and a...

The objective of this study was to compare two four-strand techniques: the traditional Strickland and cruciate techniques. Thirty-eight Achilles tendons were removed from 19 rabbits and were assigned to two groups based on suture technique (Group 1, Strickland suture; Group 2, cruciate repair). The sutured tendons were subjected to constant progres...

We evaluated 16 children with congenital pseudoarthrosis of the tibia treated with contralateral fibular graft, with the aim to report the difficulties and clinical results in the affected limb after consolidation. Sixty-three percent of the children had characteristics of neurofibromatosis. Consolidation was achieved after the main surgery in 37%o...

Resumo Objetivo Os avanços da microcirurgia reconstrutiva na cirurgia ortopédica proporcionaram melhores resultados funcionais e estéticos, evitando as muitas indicações de amputação. Nos hospitais de ortopedia e traumatologia com um grande volume de atendimento, a reconstrução microcirúrgica é essencial, a fim de reduzir os custos e as complicaçõe...

Resumo Objetivo O objetivo do presente estudo foi comparar prospectivamente os retalhos sural e propeller para cobertura de partes moles da extremidade inferior. Foram avaliadas as seguintes variáveis: incidência de perda total ou parcial do retalho e morbidade da área doadora (fechamento primário versus enxerto de pele). Métodos Análise prospectiv...
Article
Objectives: Free flaps in the pediatric population are less common and when indicated the expectations to avoid amputation are high. The objective of this study is to describe indications and results of free flaps for limb reconstruction. Methods: Patients undergoing microsurgical free flaps in an orthopedic hospital were consecutively included...
Article
Introduction The traumatic lesions of the brachial plexus in adults are devastating injuries causing continuous severe functional impairment for both work and daily living activities. The restoration of elbow flexion is one of the most important movements for patient recovery to previous activities. Free gracilis muscle transfer has good outcomes f...
Article
Background: Microsurgical flaps are widely used to treat complex traumatic wounds of upper and lower limbs. Few studies have evaluated whether the vascular changes in preoperative computed tomography angiography (CTA) influence the selection of recipient vessel and type of anastomosis and the microsurgical flaps outcomes including complications....

Objective: To evaluate if the levels of serum total protein and serum albumin are risk factors for surgical complications of free flap limb reconstruction. Methods: Consecutive inclusion of all patients undergoing microsurgical flaps for limb reconstruction of complex injuries. We recorded epidemiological and laboratory data, including total prote...
Article
Full-text available
Objective: Brachial plexus injury can lead to significant functional deficit for the patient. Elbow flexion restoration is a priority in surgical treatment. Free functional muscle transfer is an option for early or late treatment failure. This study evaluated patient characteristics and elbow flexion muscle strength after gracilis functioning muscl...

INTRODUCTION: Hand reanimation is still a challenge and, when tendon transfer or neurological reconstruction options are no longer available, the only options can be: transfer of free functional muscle transfer and transfer of the recovered bíceps to the long flexors of digits and the flexor pollicis longus. The objective of this study is to descri...

INTERROGATION: Free flaps in the pediatric population are less common and when indicated the expectations to avoid amputation is high. The objective of this study is to describe indications and results of free flaps for limb reconstruction. METHODS: From July 2014 to October 2018, patients undergoing microsurgical free flaps in an Orthopedic Hospit...

OBJETIVES/INTERROGATION: The advances of reconstructive microsurgery in orthopaedic surgery provided better functional and aesthetic results and prevented many indications of amputations. The indications of free flaps for the treatment of traumatized extremity is increasing, including, open wounds, long bone defects, muscle impairment after brachia...

Purpose Elbow flexion deficit is a frequent problem in traumatic brachial plexus injuries and reestablishment of this function is the primary treatment goal. When management is delayed, or the initial acute approach fails, free functional transfer of the gracilis muscle for elbow flexion is the treatment of choice. In this report, the authors prese...

Objective The medial femoral condyle corticoperiosteal flap is irrigated by the descending genicular artery, and when this is absent, by the superior medial genicular artery. The descending genicular artery divides into the muscular, saphenous, and osteoarticular branches. The objective of this study was to describe the variables involved in the di...

Objective: To analyze 10 consecutive cases of microsurgical arteriovenous loops created to reconstruct complex injuries from March 2011 to May 2012. Methods: This observational cohort-type study conducted by the Hand and Microsurgery Group at the HC-FMUSP included patients who were candidates for microsurgical reconstruction as a last alternative...

Purpose: Although a reasonable number of studies report satisfactory results with fibrin glue application in microvascular anastomosis since 1977, its utilization in the clinical setting has being scant in the literature. The aim of this study was to report the cumulated experience with the fibrin glue in free flaps over a period of 10 years, comp...

The purpose of this report is to critically evaluate our results of two intercostal nerve transfers directly to the biceps motor branch in complete traumatic brachial plexus injuries. From January 2007 to November 2012, 19 patients were submitted to this type of surgery, but only 15 of them had a follow-up for ≥2 years and were included in this rep...

Introduction: The aim of this retrospective study was to evaluate the restoration of shoulder flexion and external rotation by neurotization of the Suprascapular Nerve with the Spinal Accessory Nerve (SAN-SSN) in patients with severe traction injuries of the brachial plexus involving C-5 and C-6 cervical roots. Methods: Eleven SAN-SSN neurotization...

The evolution of microsurgery led to the advent of perforator flaps and the possibility to conduct anastomosis of vessels of less than 1.0 mm in diameter (super-microsurgery). The superficial circumflex iliac perforator flap (SCIP) differs from the classic groin flap by its vascularisation based on a single perforator pedicle to the skin arising fr...
