Possibilities of using short stems of hip endoprosthesis: meta-analysis

Short femoral stems of the hip endoprosthesis with femoral neck preservation facilitate the restoration of the anatomy of the proximal femur and the physiological biomechanics of the hip joint. The design of the stem is of particular interest as it allows for the creation of a hip joint with higher functional characteristics and increased service life of implants that are easier to replace. Neck-sparing short femoral stems achieve excellent early and mid-term results in both clinical and radiographic parameters that are functionally equivalent to conventional femoral stems. To date, the results of this meta-analysis indicate that neck-sparing stems may provide better bone mineral density maintenance than their conventional counterparts, in addition to lower incidence of hip pain.
