Consider Colonna Arthroplasty for Patients With Congenital Hip Dysplasia

Congenital hip dysplasia occurs in about 1 in every 1,000 babies. Common risk factors include being female and/or being a firstborn child.

A 27-year-old female with congenital hip dysplasia and chronic superior hip dislocation recently presented to Cleveland Clinic’s Hip Preservation Center. Atul Kamath, MD, director of the center and staff surgeon in the Orthopaedic and Rheumatologic Institute, said she was experiencing pain in her left hip. She presented with a significant leg length discrepancy and a limp. She had no prior history of hip surgery.

Following a complete work-up demonstrating a pseudoacetabulum, Dr. Kamath recommended a hip preservation procedure, rather than a hip replacement. Her young age and high activity level made her a good candidate for this approach.

The procedure

He opted for a particular procedure called a Colonna arthroplasty, or a capsular arthroplasty of the hip, in which a high or chronically dislocated femoral head can be put into a new or created socket. He explains, “This procedure was executed by creating a new socket, then by taking a small autograft from the ipsilateral iliac crest to create a little shelf to augment or increase the volume of the socket.”

Continuing he notes, “The femoral head was reduced into this new socket and wrapped with capsule to afford re-creation of leg length, a new hip center, and to restore bone stock for any future procedures, including total hip arthroplasty down the road if this is ever needed for pain and progressive arthritis.”

The patient is doing well and now has more normalized gait mechanics.
