Bone elongation using monolateral external fixation: a practical guide.

Salcedo Cánovas C - Strategies Trauma Limb Reconstr (2015)

Bottom Line: In the literature, we can find many articles that describe in detail specific complex procedures related to the limb reconstruction.These articles also come from a period in which the callotasis technique was being developed and, therefore, incur in discrepancies depending on the year they were written or the school of the author.This paper provides a general and summarised overview of the theoretical and practical aspects interesting to a surgeon that needs clear information on the bone elongations performed with the help of a monolateral external fixator.

ABSTRACT
In the literature, we can find many articles that describe in detail specific complex procedures related to the limb reconstruction. However, the general information on the biological and mechanical bases of callotasis is out of date, and the surgeons must relate to works dating from the early 1980s. These articles also come from a period in which the callotasis technique was being developed and, therefore, incur in discrepancies depending on the year they were written or the school of the author. This paper provides a general and summarised overview of the theoretical and practical aspects interesting to a surgeon that needs clear information on the bone elongations performed with the help of a monolateral external fixator.

Mentions: During lengthening, the soft tissue tension increases. To put a joint that is already unstable under pressure can cause its subluxation. This is very typical in patients with focal femoral deficiencies (congenital short femur) with hip dysplasia or the absence of the anterior cruciate ligament. A child with dysplastic hips could be considered unsuitable for such treatment unless we previously plan a surgical stabilization of the hip as a periacetabular osteotomy or Dega osteotomy. An unstable knee does not prevent the possibility of performing elongations, but it places the patient at risk group [10]. Patients experiencing joint instability might be candidates for the fixator to be positioned as a bridge, blocking the mobility of the joint during the lengthening phase and reducing the risk of subluxation [9] as shown in Fig. 2a, b.Fig. 2
