Mini Stem DEXA (Dual Energy X-ray Absorptiometry) (MISDexa)
The objective of this study is to evaluate the bone ingrowth after implantation of the study device. This study will also document any device-related surgical complications or adverse radiographic observations. Improvement in pain, function, and health economic data will be compared with improvements documented with other joint systems.

The purpose of the current investigation is to assess the bone ingrowth after implantation with a modular, short hip stem using Dual Energy X-ray Absorptiometry (DEXA). The intended use of this product is for patients with non-inflammatory and inflammatory degenerative joint disease who require a primary total hip replacement.
