After a total hip replacement, restrictions on flexion, internal rotation, and adduction should be maintained for how long?

Following a total hip replacement, particularly in the case of a posterior approach, it is crucial to maintain certain restrictions to prevent dislocation and ensure proper healing. The common restrictions generally include limitations on hip flexion beyond 90 degrees, internal rotation, and adduction beyond the midline. These precautions are primarily enforced in the early postoperative period when the soft tissues and hip joint are still healing and are at a higher risk of instability.

Typically, the recommended duration for these post-operative precautions is around 3 to 6 months. This time frame allows for adequate healing and adaptation of the surrounding musculature and structures to the new joint mechanics. By this point, most patients have experienced sufficient recovery, and the risk of dislocation decreases significantly, allowing for gradually reintroducing more normal movements and activities.

Overall, awareness of the appropriate duration for these restrictions helps both clinicians and patients in rehabilitation planning, ensuring that patients can safely progress through their recovery without risking complications.
