OBJECTIVE To compare the outcomes of patients with stage II SNAC submitted to surgical treatment by proximal row carpectomy (PRC) or four-corner fusion (FCF). METHOD Twenty-seven patients aged 18-59 years (mean 37.52 years) were included. Thirteen patients underwent PRC in Group A, and 14 underwent FCF of the wrist in Group B. Evaluations were made before(More)
An anomalous presentation of flexor carpi radialis brevis (FCRB) is reported in six patients. These findings occurred in a consecutive series of 172 distal radius fracture fixations using a volar approach between 2002 and 2007. This is the first report of this anomalous muscle from a clinical series.
OBJECTIVE To analyze the clinical-functional parameters and quality of life of patients undergoing minimally invasive surgical treatment for extra-articular fractures of the proximal phalanx, using an intramedullary screw (Acutrak(®)). METHODS Between January 2011 and September 2014, a prospective study was conducted on 41 patients (48 fingers) with(More)
Objectives To measure the quality of life, the time to work return, and clinical, functional, and radiographic parameters of patients treated with dorsal capsulodesis associated with scapholunate (SL) reconstruction, assisted by arthroscopy. Methods From January 2015 to September 2016, 14 adult patients with SL dissociation underwent surgical treatment(More)
OBJECTIVE To compare the mechanical parameters between two methods for stabilization through compression: 1.5 mm axial compression plate versus conical compression screw used as an intramedullary tutor. METHODS Polyurethane models (Sawbone(®)) that simulated transverse fractures of the proximal phalanx were used. The models were divided into three groups:(More)
We present 20 patients, who had a four corner arthrodesis, from July 2006 to March 2008, using a dorsal circular plate, to treat scaphoid nonunion and scapholunate dissociation with advanced collapse (SNAC, SLAC). The surgical technique was a fusion restricted to the central area filled with one piece of cancellous bone graft taken from the excised(More)
OBJECTIVES the purpose of this study was to compare the postoperative radiological and clinical outcomes with minimally invasive percutaneous osteosynthesis using three implants: volar locking plate, intramedullary nail system and nonbridging external fixator for distal radius fractures. METHODS forty-eight patients (A group, 16; B group 16; C group 16)(More)
OBJECTIVE To present the clinical and functional results, including measurement of quality of life, of patients undergoing trapeziometacarpal arthroplasty. METHOD This was a prospective evaluation on 45 patients (53 thumbs) with a diagnosis of idiopathic rhizarthrosis who underwent resection arthroplasty and interposition of an uncemented Ascension(®)(More)
OBJECTIVE To measure the quality of life and clinical-functional results from patients diagnosed with osteoarthrosis of the distal radioulnar joint who underwent surgical treatment using the technique of total arthroplasty of the ulna, with a total or partial Ascension(®) prosthesis of the distal ulna. METHODS Ten patients were evaluated after 12 months(More)
