Aims. The purpose of this study was to analyze the initial experience with adolescents treated for long-bone deformities of the lower extremities of different etiologies using osteotomies and fixation by interlocking nails.Materials and methods. We analyzed the accuracy of long-bone deformity correction using referent lines and angles, the time of consolidation, number of complications, and functional result.Results. We found that the accuracy of femur deformity correction (dependent on the complicity of the deformity), as estimated by different parameters, varied from 77.8% to 91.7%. Simple deformities and deformities of moderate complicity had the most accurate correction; the group of complex multiplanar deformities of the femur had the least accurate correction. This group included five cases of residual deformity, in which three of these had an angle of residual deformity <10°. The accuracy of leg deformity correction was 90%. Evaluation of the functional results using the Lower Extremity Functional Scale indicated the high functionality of the method used.Conclusions. Correction of long-bone deformities using intramedullary osteosynthesis by interlocking nails is an effective treatment of all types of femur and lower leg deformities. When treating complex deformities of the femur, the path to operative treatment should be complex and in most cases the nailing should be accompanied by intraoperative external fixation frame assistance.

Aim. To retrospectively assess treatment outcomes of long bone deformities of the lower extremities accompanied by shortening in pediatric patients using a software-assisted Ortho-SUV Frame.Materials and methods. The accuracy of deformity correction (AC), period of deformity correction (PDC), external fixation index (EFI), and number of complications in 213 patients were retrospectively analyzed.Results. According to different parameters, AC of femur deformity correction (group 1) varied from 90% to 96%. The average length increase was 47 ± 12 mm. The average distraction duration was 38 ± 14 days. The average PDC was 8 ± 6 days for simple deformities (SDs), 14 ± 7 days for moderate deformities (MDs), and 23 ± 12 days for complex deformities (CDs). EFI was 26 ± 8 days/cm for SDs, 31 ± 6 days/cm for MDs, and 35 ± 12 days/cm for CDs. According to different parameters, AC of the lower leg deformity correction (group 2) varied from 89% to 95%. The average length increase was 52 ± 20 mm. The average distraction duration was 45 ± 18 days. PDC was 11 ± 5 days for SDs, 16 ± 9 days for MDs, and 27 ± 16 days for CDs. EFI was 32 ± 14 days/cm for SDs, 42 ± 12 days/cm for MDs, and 49 ± 8 days/cm for CDs. There were 48 (50.5%) complications in group I with the majority (71%) classified as Caton grade I and 29% as grade II. There were 62 (45%) complications in group 2, where 50% were Caton grade I and 50% were Caton grade II. There were no serious complications (Caton grade III) in either group that influenced the final functional results.Conclusion: Use of a software-assisted Ortho-SUV Frame increased the efficiency of treatment of pediatric patients with long bone deformities because of the great accuracy of deformity correction.

Back ground and objectives The treatment of Gap or Defect non-union presents a formidable challenge to Orthopaedic surgeons. Not only a union but also good functional outcome is the target of modern-day Orthopaedics. The objective of this study is to consider knowledge of all treatment modalities, time frame, and functional results of long bone defects and develop an algorithm. Summary The study is designed as retrospective, prospective observational study. It is conducted in tertiary care hospital (MIOT Hospitals, Chennai). Initial evaluation of all cases were done by Maurizio Catagni’s Classification. Type of surgeries, time spent in hospital, union time were calculated. Patients were followed up for a period of 1year. Patients with average defect size of 6.29cm on an average underwent 4.47 procedures and for an overall time of 17.8 weeks with around 83.80 % of individuals were able to return to their preinjury activity level. Analysis of all data was done and algorithm developed.

Introduction. Nonunion of long bones may often be associated with significant function loss of affected extremity, joint stiffness, and even extremity amputation or systemic manifestations in the case of infection. The aim of this case report is to highlight the possibilities of Ilizarov apparatus in the treatment of fracture nonunions of both lower legs treated by different operative methods and to show that it is not necessary to remove osteosynthetic material (intramedullary nail) in every case when nonunion occurs to achieve its recovery. Case Report. A 62 year-old man was injured in a traffic accident as a pedestrian in April 2012, when he experienced polytrauma, including shaft fracture of the right femur, and segmental open fractures of the right (Gustillo-Anderson grade I) and left (Gustillo-Anderson grade II) lower leg. The fractures of right femur and right tibia were stabilized initially with intramedullary nails, while the left lower leg fracture was treated by unilateral external fixator. After 5 months, there were no clinical and radiographic signs of union on lower legs, therefore the patient underwent re-surgery. Ilizarov apparatus was applied on both lower legs. The patient was early verticalized and both apparatus were removed after 4 months. According to the modified protocol of the Association for the Study and Application of Methods of Ilizarov, the lower leg bony results were good and excellent, and the functional results were excellent on both sides. Conclusion. Nonunion fracture of the right lower leg initially treated by the method of intramedullary osteosynthesis and afterwards by placing Ilizarov apparatus shows that in some cases it is not indicated to remove fixative material in order to achieve full recovery of fracture, thus eliminating the danger of all negative effects resulting from the classical extensive surgical treatment.

Angular Deformities

SummaryThe IMEX™ Circular External Skeletal Fixation (CESF) System was used to treat 10 antebrachial deformities in nine dogs. The mandible of one dog with prognathism was also lengthened. Dogs ranged in age from four to 18 months (mean ± SD: 9 ± four months; median: eight months) and body weight from 2.6 to 46.0 kg (mean ± SD: 23.9 ± 11.2 kg; median: 24.2 kg). Linear distractions were performed with linear motors or threaded rods with paired nylon nuts securing the connecting rods to rings placed between ring blocks. Hinges and angular motors were used to correct angular deformities. A latency period of two to six days and a distraction rate of 1 mm/day, with a twice daily rhythm, were used. Distraction periods ranged from 12 to 32 days (mean ± SD: 21 ± 8 days; median: 25 days). Lengthening achieved ranged from 11 to 40 mm (mean ± SD: 20 ± 9 mm; median: 18 mm) or 6 to 30% (mean ± SD: 15 ± 8%; median: 13%) of the distracted bone’s initial length. All dogs had substantial improvement of their deformity and effective regenerate bone formation. Flexure contracture and wire and pin track inflammation were common complications during the convalescent period. Functional and cosmetic results (direct examination: mean ± SD: 130 ± 65 days; median: 123 days; telephone communication: mean ± SD: 351 ± 133 days; median: 324 days) were assessed as excellent in six, good in three and fair in two dogs and excellent in five, good in four and fair in one dog, respectively. The IMEX™ CESF system allowed precise deformity correction with minimal morbidity which was attributable to the system’s zero tolerance, zero motion properties.The IMEX™ Circular External Skeletal Fixator System was used to treat antebrachial deformities in nine dogs and to lengthen the mandible of one dog with prognathism. Functional results were assessed as excellent in six dogs, good in three dogs and fair in two dogs. Cosmetic results were assessed as excellent in five dogs, good in four dogs and fair in one dog.Presented at the 23rd Annual Conference of the Veterinary Orthopaedics Society, Telluride, CO, USA, March 5, 1996.
