The hip joint or coxofemoral joint is a synovial joint of the enarthrosis type. Allows movements in different planes; in the sagittal plane it allows flexion and extension movements, in the coronal plane it allows abduction and adduction movements while in the transverse plane it allows both internal and external rotation movements. In addition, these joints also perform circumduction movements.
