ABSTRACT
The necessity of a surgical approach to the lesser trochanter is fairly rare event that occurs more frequently in the treatment of tumours situated in this anatomical area. The authors described four cases of osteocartilaginous neoplasms situated in proximity of the lesser trochanter. In two cases the mass was removed through a medial surgical approach (Ludloff); in one case through a postcolateral approach (Gibson), in one case through an anterior approach (Smith-Petersen). Each of the used approaches gives a good light on the lesser trochanter, therefore the choice of surgical approach is essentially determined by the prevalent spatial situation of neoplasm. Among the instrumental examinations available the Authors remark the importance of T.A.C. in the spatial visualization of neoformation.
