  ABSTRACT: The extended trochanteric osteotomy (ETO) is widely used for revision total hip arthroplasty (THA). We describe a novel technique to reattach the extended trochanteric osteotomy using a suture cord. We retrospectively reviewed 20 patients who underwent revision by this technique with a minimum followup of 2 years (mean, 2.2 years; range, 2-4 years). Bony union of the osteotomy occurred in 19 patients and fibrous union in one patient who remained asymptomatic. We observed proximal migration of the osteotomy fragment in one patient (5 mm) who had bony union of the osteotomy. This technique of anchoring the osteotomy fragment directly onto the prosthetic stem using a suture cord provides a secure fixation and does not endanger the blood supply of the osteotomy. It also has the advantage of avoiding the morbidity associated with cerclage wires and the costs associated with cabling systems. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

  ABSTRACT: The authors present a simple and cost effective technique of preparing strong cords from surgical sutures. The technique requires suture material, a drill, a clip and it takes less than a minute to prepare. The mechanical strength of the cord obtained by this method was compared to the mechanical strength of a single suture. Cords containing eight thicknesses of the suture material failed at slightly under eight times the single suture strength. A loop made out of cords of number 2 Vicryl or Dexon failed at loads of more than 1000 N. The authors have found these cords extremely useful and effective for reconstruction of the dislocated acromio-clavicular joint and also for the fixation of trans-femoral osteotomies.
