A new surgical method for treating patients with refractory external snapping hip: Pedersen-Noor operation.

The technical description of a new surgical method (Pedersen-Noor operation) to treat refractory external snapping hip [coxa saltans externa (CSE)] is presented. The method consists of distal lengthening of the iliotibial band by Z-plasty under local anesthesia and on an outpatient basis. Five patients with refractory CSE were treated with the new method. Postoperatively, the outcome was evaluated by phone interview and physical examination, 3 to 4 months and 1 year postoperatively, respectively. The snapping disappeared in all five patients. No postoperative complications were reported. Three patients were very satisfied and two patients were satisfied with the result of the operation. All five patients would recommend the operation to another patient with similar symptoms. The described method is simple, economic, and effective and can be recommended in the treatment of refractory CSE.
