In-situ hip arthroplasty can improve restoration leg length measurement

The use of in-situ hip arthroplasty allows for improved leg length measurement and restoration.

Speaking to Orthopaedics Today, surgeon William Kurtz said that the technique also allows for femoral component implantation prior to femoral neck osteotomy without the need for hip joint dislocation.

He told the news provider: "This technique moves the measurement of the leg length as close to the centre of rotation as you can.

"The device is removable and re-attachable as many times as you want, and it gives you the ability to anatomically recreate the hip."

He added that the technique also uses a skill set that every orthopaedic surgeon already has - that of being able to nail a femur.

Kurtz looked at 100 hips in 93 patients who were treated with the in-situ technique. Pre- and post-operative leg length measurements were obtained using radiographs.

Leg length inequality was recently linked to the development of osteoarthritis by a cohort study funded by the National Institute of Aging.
