Biomechanical Features

Biomechanical features of long bones indicate that external fixation of long bone fractures have to be balanced according to general transversal stability as more as possible. The aim of this work was to investigate the influence of orientation pins to the general transversal stability of external fixation of fractures of long bones. In this study we have used the model of fractured long bone made of wood which was treated by Mitkovic external fixator with 4 pins, in 3 different situations: 1. all pins are in one axial plane, 2. each 2 pins are in 2 axial planes with angle distances of 60o, 3. each 2 pins are in 2 axial planes wich are normal to each other. Means of relations of measured movements of long bone model fragments during the use of perpendicular force from 2 directions, normal to each other, after grouping of results in 3 groups: 0,17, 0,46 i 0,72. Statistical analyses showed that the differences between each of 3 groups were significant (p<0,05). It can be concluded that it is better if pins are oriented in different axial planes, with pretension that both planes are normal to each other, during external fixation of long bone fractures.

In this study, the advantages and disadvantages of Ilizarov external fixator in the treatment of long bone fractures in calves were investigated. For this purpose, 26 calves of different breeds, ages and genders, having metacarpal (n = 12), metatarsal (n = 5) and antebrachial (n = 9) fractures underwent surgery under general anaesthesia. Frames, which were prepared before surgery in accordance with the radiographic findings, were applied under open reduction in 18 cases, and under closed reduction in eight cases. In the postoperative period, all calves except one started to bear some weigh on the injured limb on the first day, while the remaining calf did the same on the second day. The consolidation started in the first 2 weeks for 24 of the calves and was completed by the day 55. In the two remaining cases, it started in the third week and was completed on day 71 and day 90, respectively.The soft tissue wounds were completely healed in all calves and no complications occurred. In five calves that were not kept in our clinic pin tract infections formed. They were controlled rapidly, and there was no change in the fracture reduction or healing duration.In conclusion, in our study, the Ilizarov external fixator system was applied to long bone fractures in cattle calves, in cases where the fragments were not large enough to apply pins and plates, and which became open and infected after defective bandage practices or unsuitable treatment. Fractures completely healed in all cases, without any complications. These results show that many of the long bone fractures experienced by calves, that were considered for amputation due to the anticipated inability to treat them successfully, could be treated with the use of the Ilizarov system.

<p class="abstract"><strong>Background:</strong> Nonunion of long bone fractures is a common condition treated by an orthopaedic surgeon. Many nonunions can be treated effectively by internal fixation with or without bone grafting but, an infected nonunion can prove to be a tough challenge. The Ilizarov method is effective in managing infected nonunion of long bones. This study aims to assess the outcome of management of infected nonunions of long bones of lower limb with Ilizarov Ring fixator using bone and functional results as per Association for the Study and Application of Methods of Ilizarov (ASAMI) Scoring System.</p><p class="abstract"><strong>Methods:</strong> We retrospectively analysed 18 patients (16 Male: 2 Female; Mean age 43.2 years) managed with Ilizarov technique for an infected tibial or femoral nonunion between 01 January 2013 and 31 December 2014. They were followed up for an average of 25.4 months after removal of fixator. They were assessed for functional and Bone (radiological) outcomes using the Association for the Study and Application of Methods of Ilizarov (ASAMI) criteria.<strong></strong></p><p class="abstract"><strong>Results:</strong> 17 limbs were salvaged and union could be achieved. One limb required amputation due to severe persistent intractable infection. None required any additional skeletal stabilisation after removal of fixator frame except casting in a few patients for a period of 6 weeks. Mean time to union was 211.83 days (range 136 - 320days/median 184) or 7.01 months. As per the ASAMI score, Bone results were excellent in 10, good in 5, fair in 2 and poor in 1. Functionally 7 were graded as excellent, 6 as good, 3 as fair and 1 as poor and 1 patient underwent amputation.</p><p><strong>Conclusions:</strong> The Ilizarov’s method remains one of the most versatile and successful means of achieving bone healing in infected nonunions of long bones of lower limbs with additional benefits of correcting bone defects, deformities and limb length inequalities. </p>

Аbctract. Treatment of long bones fractures of the extremities has a particular relevance in modern traumatology due to their high frequency, as well as a large number of deaths in patients with polytrauma. It is dangerous to perform an urgent final osteosynthesis in severe patients because of the possibility of shock and the deterioration of the condition of the injured. Therefore, the principle of Damage control with urgent fixation of damaged segments by external fixation and their subsequent replacement (converse) to intramedullary osteosynthesis had a particular relevance in the treatment of patients with long bones fractures. Purpose: Improving treatment outcomes for patients with long bones fractures. Materials and methods. In the present study, a retrospective analysis of using conversion osteosynthesis in the treatment of 120 patients with long bones extremities fractures in a multidisciplinary hospital was carried out. For a better analysis of the results of treatment, we divided the patients into two groups: The first group 44 patients with fractures of the long bones with polytrauma according to the ISS severity scale> 17. The second group consists of 76 patients with closed isolated unstable comminuted fractures of the long bones with severe post-traumatic edema, who have a high risk of significant trauma of soft tissues. Results. The most optimal time for conversion osteosynthesis to patients with polytrauma was 7-12 days, which prevented the occurrence of traumatic shock; and for patients with closed isolated unstable fractures of long bones with significant of post-traumatic edema for conversion osteosynthesis, the optimal time was 3-7 days after injury, which prevented the occurrence of inflammatory complications in the postoperative period. Conclusion. The study confirmed the feasibility of conversion osteosynthesis in the treatment of patients with diaphyseal fractures. The use of the technique of transferring the fixation of fragments by the external fixation device to the internal osteosynthesis (conversion) contributed to a reduction in the duration of inpatient treatment of patients with fractures of the long bones.

Long Term Prognosis

While most obstetricians are familiar with fracture of the clavicle in newborns during birth, an unlucky minority of obstetricians has encountered long-bone fractures in newborns as well. This complication is traumatic not only for the neonate, but also for the family and the obstetrician; it is also difficult to explain. Fortunately, the long-term prognosis for fracture of the long bones is excellent. Both vaginal and cesarean breech deliveries and maneuvers can be responsible for birth traumas, including long-bone fractures. This case report presents a newborn with breech presentation delivered vaginally that resulted in humerus diaphysis fracture.
