    HALLUX RIGIDUS: PROSPECTIVE STUDY OF JOINT REPLACEMENT WITH HEMIARTHROPLASTY
    (2013) SANTOS, Alexandre Leme Godoy dos; DUARTE, Fernando Aires; SEITO, Carlos Augusto Itiu; ORTIZ, Rafael Trevisan; SAKAKI, Marcos Hideyo; FERNANDES, Tulio Diniz
    Objective: To report the results of medium-term follow-up after deploying Arthrosurface-HemiCap (R) in patients with diagnosis of Hallux Rigidus (HR). Method: Eleven patients underwent partial Arthroplasty of the first metatarsal-phalangeal joint. Six women and five men with an average age 51.9 years (46 to 58 years) and average postoperative follow-up of 3.73 years (3-4 years); were classified through the Kravitz system and evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) scales for hallux, Visual Analogical Scale (VAS) - analog functional pain - and range of motion in the first metatarsal joint in preoperative, postoperative after six months and present post-operative. Results: The results show significant improvement of the three analyzed parameters, both for overall analysis and for pre and post-operative comparisons individually. The comparative analysis of each variable in the six months and the current postoperative periods do not show statistically significant differences, indicating maintenance of parameters during this interval. Conclusion: hemiarthroplasty of first metatarsophalangeal joint is a reproducible and safe option for the surgical treatment of hallux rigidus II and III, with significant improvement of the evaluated parameters for the studied population.

    SHOULDER ARTHROPLASTY IN OSTEOARTHRITIS: CORRELATION BETWEEN FUNCTION AND RADIOGRAPHIC PARAMETERS
    (2013) GRACITELLI, Mauro Emilio Conforto; DUARTE, Fernando Aires; TOFFOLI, Rogerio Padovani; BURNATO, Joao Henrique; MALAVOLTA, Eduardo Angeli; FERREIRA NETO, Arnaldo Amado
    Objectives: To evaluate the correlation between radiographic parameters and functional assessments of patients with osteoarthritis of the shoulder who underwent shoulder arthroplasty and to describe the functional outcomes of this procedure in our institution. Methods: We evaluated 21 patients (22 shoulders) who underwent shoulder arthroplasty between 1998 and 2010 and with a minimum follow-up of 12 months. Clinical evaluation was performed using the Constant-Murley scale, UCLA, EVA and by measuring the active motion. We analysed preoperative (distance between the top of the head and the humerus and the acromion, superior migration, neck angulation, medial ""offset"", subluxation, glenoid erosion) and postoperative radiographic parameters (rod inclination, migration of components and loosening). Results: Patients showed significant improvement in all parameters: flexion (p = 0.0083), abduction (p = 0.0266), external rotation (p = 0.0062), Constant-Murley (p = 0.0001), UCLA (p < 0.0001) and VAS (p = 0.0002). The superior migration of the humerus showed a significant correlation with UCLA and Constant-Murley scores (p = 0.0480 and p = 0.0110, respectively). The other radiographic parameters showed no correlation with the clinical outcomes. Conclusion: The superior migration of the humerus is related to worse clinical scores.
