Purposes of the study. To assess safety, lengths gained, frame time and perform cost analysis of the technique of submuscular plating to the femur and tibia following distraction osteogenesis. Introduction. Since 2005 we have performed submuscular plating to the femur and tibia after distraction osteogenesis in order to shorten time in external fixator. Aim. To assess safety, lengths gained, frame time and perform cost analysis. Methods. Retrospective analysis using notes and digital radiographs, with cost codes for 2011 prices. Patients. 23 patients (14 male), mean age 11 (range 4 to 17). 14 diagnosed as congenital longitudinal deficiency. Total 37 bones lengthened (14 femur and tibia, 7 tibia only, 2 femur only). Ilizarov fixator most commonly used for tibia, LRS fixator for femur. Results. Mean length gained 68 mm per patient, 43 mm per bone. Mean frame time 121 days. Fixator index 0.59 months/cm per patient, 0.90 months/cm per bone. Mean cost £20100 per patient, £12500 per bone, £2800 per cm length. Cost attributable to plating £5100 per patient, £3300 per bone. Complications: 5/24 had pinsite infections, 2/24 required tendon releases, 1/24 had deformity, 1/24 sustained a fracture proximal to femoral plate. No deep infections. Conclusions. Plating after lengthening is a safe procedure with no deep infections. The frame time is low (0.6 months/cm per patient) but increases overall costs by an extra £5000

Aims. Since 2005 we have performed submuscular plating to the femur and tibia after distraction osteogenesis in selected cases in order to shorten the time in external fixator. The aim was to assess safety, lengths gained, frame time and perform cost analysis. Methods. Retrospective analysis using notes and digital radiographs, with cost codes for 2011 prices. 23 patients (14 male), mean age 11 (range 4 to 17) were analysed. 14 were diagnosed as congenital longitudinal deficiency. Total 37 bones lengthened (14 femur and tibia, 7 tibia only, 2 femur only). Ilizarov fixator most commonly used for tibia, LRS fixator for femur. Results. Mean length gained 68mm per patient, 43mm per bone. Mean frame time 121 days, with mean 75 days of lengthening, and mean 46 days between the cessation of lengthening and the plating procedure. Fixator index 0.59 months/cm per patient, 0.90 months/cm per bone. Mean cost £20100 per patient, £12500 per bone, £2800 per cm length. Cost attributable to plating £5100 per patient, £3300 per bone. Complications: 5/24 had pinsite infections, 2/24 required tendon releases, 1/24 had deformity, 1/24 sustained a fracture proximal to femoral plate. No deep infections. In terms of patient satisfaction, families of patients who had also undergone a prior lengthening with frame only, 80% preferred plate after lengthening. Conclusions. Plating after lengthening is a safe procedure with no deep infections. The frame time is low (0.6 months/cm per patient) but increases overall costs by an extra £5000 per patient. There is room to improve the fixator index further if the time between cessation of lengthening and the plating procedure (currently 46 days) is shortened

External fixation is widely used in orthopaedic and trauma surgery. Infections around pin or wire sites, which are usually localised, non-invasive, and are easily managed, are common. Occasionally, more serious invasive complications such as necrotising fasciitis (NF) and toxic shock syndrome (TSS) may occur.

We retrospectively reviewed all patients who underwent external fixation between 1997 and 2012 in our limb lengthening and reconstruction programme. A total of eight patients (seven female and one male) with a mean age of 20 years (5 to 45) in which pin/wire track infections became limb- or life-threatening were identified. Of these, four were due to TSS and four to NF. Their management is described. A satisfactory outcome was obtained with early diagnosis and aggressive medical and surgical treatment.

Clinicians caring for patients who have external fixation and in whom infection has developed should be aware of the possibility of these more serious complications. Early diagnosis and aggressive treatment are required in order to obtain a satisfactory outcome.
