Orthopaedic Surgeon Corrects Rare Leg Deformity Called Miser
Brittany Corso was born with a rare leg deformity that caused debilitating pain in her knees and ankles.

In this rare condition called miserable malalignment syndrome, Ms. Corso’s femurs (thigh bones) were excessively rotated inward, while her tibiae (shinbones) were excessively rotated outward, putting stress on her joints.

Dr. Bernstein corrected the problem by performing a specialized surgery on the left leg, followed six weeks later with the same surgery on the right leg. He cut the femur in half (a procedure called an osteotomy) and then rotated the two segments back to a normal position. The femur was stabilized with an internal rod. Dr. Bernstein also performed an osteotomy on the tibia and fibula (the smaller of the two bones of the lower leg). He then attached a computer-controlled external device that gradually rotated the segments of the lower leg to the proper positions.
