MAURAS, Julio R. Results of Experimental Studies and Clinical Evolution in Reconstructive Surgery with Osteointegrated Polymer. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2011, vol.76, n.2, pp. 122-132. ISSN 1852-7434.
Background: bone substitutes are man-made materials. They are supplied in various forms and have proven their effectiveness in different reconstruction types. Methods: From March 2003 to March 2010 twenty eight (17 females and 11 males) surgical interventions were performed on the hip joint. 26 cases were revision surgery and only 2 were primary arthroplasties. Average age at the time of surgery was 62.6 years (range 52-88). Results: The results were classified in clinical-radiological and experimental; different parameters were considered: resistance to compression in acetabular designs, cadaver femurs, and recovered acetabuli. Electron microscopy images were obtained and the volumetric behavior at the end of the expansion phase was measured. Clinical-radiological results were rated according to their advantages in the rehabilitation, functional recovery, absence of pain, osteointegration in time, and absence of implant subsidence or migration. Conclusions: As with all experiences in medicine, this is the beginning of new techniques that have served so far to solve difficult problems in a faster, safer and more practical manner.
