Periarticular soft tissue calcification and ossification in the septic joint

We encountered three infants who developed juxta-articular calcification adjacent to the anterolateral aspect of the ilium. All had had drainage of a septic hip using an anterior approach. Calcification was not found among five infants whose septic hips were drained using a posterior approach. Some surgeons who employ the anterior approach facilitate exposure of the joint capsule by elevation of the origins of the sartorius and rectus femoris muscles. We feel this juxta-articular calcification in this setting is a sequla of anterior surgical drainage of the hip in which there has been surgical elevation of the iliac periosteum. It does not imply an unfavorable outcome.
