[Modular Neck in Primary Total Hip Replacement--A Justifiable Risk?]

Modular necks are considered as a treatment option in primary total hip replacement aiming to allow a variable reconstruction of the hip joint. Concerns are related to increased failure and complication rates which may be associated with the additional modular interface. This interface is frequently affected by corrosion processes which may initiate premature failure of the entire implant. In this study the risk of modular necks as a clinical treatment option is evaluated. Based on register data and clinical studies modular necks should only be used with strict limitations for general treatment in primary total hip replacement.
