Introduction

Fracture non-union is a devastating cause of patient morbidity. The cost of NU treatment ranges from £7,000 to £79,000. With an estimated 11,700 cases in the UK pa the financial implications are huge, potentially costing several hundreds of million of pounds annually.

Successful outcome in the management of non-union is based upon correctly identifying the underlying cause(s) and addressing them appropriately.

Aim

The aim of this study was to assess the causative factors in non-union in order to optimize the management of non-union. The causes of NU were categorized into 4 groups (infection, dead bone/gap, host factors, mechanical).

Femoral lengthening using the Intramedullary Skeletal Kinetic Distractor is a new technique. However, with intramedullary distraction the surgeon has less control over the lengthening process. Therefore, 33 femora lengthened with this device were assessed to evaluate the effect of operative variables under the surgeon’s control on the course of lengthening. The desired lengthening was achieved in 32 of 33 limbs. Problems encountered included difficulty in achieving length in eight femora (24%) and uncontrolled lengthening in seven (21%). Uncontrolled lengthening was more likely if the osteotomy was placed with less than 80 mm of the thick portion of the nail in the distal fragment (p = 0.052), and a failure to lengthen was more likely if there was over 125 mm in the distal fragment (p = 0.008). The latter problem was reduced with over-reaming by 2.5 mm to 3 mm. Previous intramedullary nailing also predisposed to uncontrolled lengthening (p = 0.042), and these patients required less reaming.

Using the Intramedullary Skeletal Kinetic Distractor, good outcomes were obtained; problems were minimised by optimising the position of the osteotomy and the amount of over-reaming performed.
