  • Title: Leg lengthening.

    Journal: J R Coll Surg Edinb; 1993 Apr; 38(2):101-4. PubMed ID: 8478826.
    Abstract:
    The combined experience of the Royal Hospital for Sick Children, Glasgow and the Robert Jones and Agnes Hunt Orthopaedic Hospital, Oswestry in lengthening 52 lower limb segments with the Orthofix device is reviewed. Forty-eight segments were lengthened by callotasis, 24 in patients with achondroplasia. Attempted lengthening with chondrodiatasis was performed in 4 patients with leg length discrepancy. With callotasis, planned lengthening was achieved in 43/48 (90%) of segments. There was a small number of significant complications. Angulation or buckling of the new bone was the commonest major complication, and was seen in 10% of segments. Pin tract infection was the predominant minor complication. Premature union was noted commonly in the femurs of achondroplastics, but could usually be overcome with manipulation under anaesthesia. We confirm that callotasis achieves its objectives with fewer complications and operations than the commonly used Wagner method which it should supersede. By contrast, we had major complications in all cases with chondrodiatasis and have abandoned this method.
