    Comparison between proximal row carpectomy and four-corner fusion for treating osteoarthrosis following carpal trauma: a prospective randomized study
    (2011) BISNETO, Edgard Novaes Franca; FREITAS, Maura Cristina; PAULA, Emygdio Jose Leomil de; MATTAR JR., Rames; ZUMIOTTI, Arnaldo Valdir
    OBJECTIVE: To compare the functional results of carpectomy and four-corner fusion surgical procedures for treating osteoarthrosis following carpal trauma. METHODS: In this prospective randomized study, 20 patients underwent proximal row carpectomy or four-corner fusion to treat wrist arthritis and their functional results were compared. The midcarpal joint was free of lesions in all patients. RESULTS: Both proximal row carpectomy and four-corner fusion reduced the pain. All patients had a decreased range of motion after surgery. The differences between groups were not statistically significant. CONCLUSIONS: Functional results of the two procedures were similar as both reduced pain in patients with scapholunate advanced collapse/scaphoid non-union advanced collapse (SLAC/SNAC) wrist without degenerative changes in the midcarpal joint.

    ARTHROSCOPIC AND MACROSCOPIC EVALUATION OF THE LUNATE MEDIAL FACET
    (2011) BISNETO, Edgard de Novaes Franca; SOUSA, Bruno de Biase Cabral de; PAULA, Emygdio Jose Leomil de; MATTAR JUNIOR, Rames; ZUMIOTTI, Arnaldo Valdir
    Objective: To evaluate the correlation between the presence of a lunate medial facet and the incidence of ligament lesions of the wrist and arthrosis of the proximal pole of the hamate. This study was carried out on cadavers. Methods: Arthroscopic evaluation and dissection were performed on cadaver wrists. Results: There was a clear, statistically significant correlation between arthrosis of the proximal pole of the hamate and the presence of a medial facet on the lunate. Conclusion: Arthrosis of the proximal pole of the hamate is correlated with the presence of a type II lunate. Level of Evidence III, Study of nonconsecutive patients; without consistently applied reference ""gold"" standard.

    Avaliação histológica da neurorrafia término-lateral. Estudo experimental em ratos
    (2011) SOUZA, Fabiano Inacio de; SANTOS, Gustavo Bispo dos; SILVA, Ciro Ferreira da; MATTAR JUNIOR, Rames; ZUMIOTTI, Arnaldo Valdir
    Objective: The aim of this study was to histologically compare the axonal sprouting after end-to-side neurorrhaphy with or without epineurotomy. Methods: twenty male Wistar rats were used, divided into two groups of 10 rats each. A 1.0cm segment of the tibial nerve E was dried and sutured on the opposite side, where it was sutured into the sciatic nerve D. In Group I, the suture was made directly in the epineurium and in Group II, epineurotomy was performed. After 4 weeks, histological evaluation was carried out of the transposed segment and the sciatic nerve distal to the suture. Results: the results showed a small number of remyelinated fibers, varying from 7 to 51 fibers in Group I and from 10 to 91 fibers in Group II. The Mann-Whitney U test was used, with p=0.311, showing there is no statistically significant difference between the two groups. There was no positive relation between the number of remyelinated fibers in the graft and in the suture site distal to the sciatic lesion. Conclusion: lateral-ending neurorrhaphy, with or without epineural window, does not promote efficient remyelinization. Level of Evidence: Level II, prospective comparative study.
