Our data show that the acetabular spacer technique is able to reduce the interstage complication rate and allow improved hip biomechanics restoration.

A 12-year-old girl presented with three yellowish polypoid lesions in the lateral border of tongue since birth. Histological examination showed oral mucosa covered by squamous epithelium and an underlying vascularized fibrous stroma, containing small and short bundles of striated muscle, corresponding to a rhabdomyomatous hamartoma.

Purpose This study is a retrospective analysis of our experience in microsurgical bone transfers for complex limb reconstructions. The aim of this study is to evaluate reliability of the vascularized fibula technique: infection recurrence, hypertrophy, time to bone union, complications, and time to healing in severe osteomyelitis (Cierny-Mader III and IV) cases over a 38 to 93 month follow-up. Patients and Methods From March 2010 until December 2015, 18 patients’ limbs (6 females and 1 2 males; mean age 48.7 years) were reconstructed with 10 free fibula flaps, 5 pedicled fibula flaps, 3 peroneus brevis osteomuscular flaps. We reconstructed 2 radiuses, 2 ulnae, 4 femurs, 4 tibiae, 1 acetabulum and 3 fibular malleoli. Results We considered as successful results all cases where patients had successful functional bone reconstruction with no recurrence of infection during the follow up (mean time 63.6 months). We obtained 14 complete functional reconstructions, 2 limb salvages with impaired function, and 2 failures which underwent major amputations. In only one case there was an infection recurrence. Conclusions The bone defect reconstruction with vascularized fibula grafts in severe bone infections is an effective option, but requires a well trained multidisciplinary team to manage the high rate of complications. Complications, in our series, were demonstrated to be significantly associated to patients defined as B-hosts according to Cierny-Mader’s classification (P < 0.05), and caliber discrepancy between fibula and reconstructed bones such as Tibia and Femur (P < 0.005). Furthermore, stress fractures in the grafted fibulae were prognostic indicators for overall treatment failure (P < 0.05).
