The Subject

Objective The aim of this study was to evaluate epoxy-pin external skeletal fixation technique for the treatment of open fractures in calves and foals. Study Design Twenty-eight calves and four foals (weighing 45–105 kg) with fractures distal to the stifle or elbow made the subject for the retrospective study. The pins (2.0–3.0-mm Kirschner wires, crossed at 60–90°) were fixed at least at two locations in both proximal and distal bone fragments as per the case situation. The pins in the same plane were bent (∼2 cm from the skin) towards the fracture site or joint and were joined using an adhesive tape (additional pins used when required) to make a temporary scaffold of connecting bars or rings. Thoroughly mixed epoxy putty was applied along the pin scaffold (the epoxy columns were 20–25 mm diameter) and allowed to set for 45 to 60 minutes. All animals were evaluated based on various clinical and radiographic observations made at regular intervals. Results The epoxy-pin fixation was easy to apply and provided stable fixation of bone as indicated by early weight bearing, and fracture healing within 45 to 60 days (17/32 cases). The functional recovery was good to very good in 14 animals and satisfactory in nine cases by 12 months after removal of the fixator. Conclusions The multiplanar epoxy-pin external skeletal fixation provides stable fixation of unstable open fractures distal to the stifle or elbow joint; hence, it can be used to treat a variety of fractures in calves and foals weighing up to approximately 100 kg, especially open infected fractures of lower limb, which are difficult to treat by conventional techniques.

Using Data

Osteosynthesis with LISS system (less invasive stabilization system) is a new technology and this conception of stabilization of long bone fragments is a new step in the development of AO philosophy. Indications to application of this system are distal metaepiphysis and diaphysis femur fractures, supra- and transcondylar fractures in polytrauma, fractures in osteoporosis as well as fractures after total knee replacement. During the last 3 years 35 patients were operated on by that technique. The follow-up period ranged from 6 months to 3 years. Assessment of outcomes was performed using data of clinical examination and evaluation of radiograms with modified Neer-Grantham-Shelton scale. In patients who were operated on I year ago the total score varied from 70 to 80 (maximum - 100). Advantages of this technology as compared to the traditional methods of osteosynthesis are the following: limited operative trauma, less blood loss, shortening of surgery duration, preservation of tissue physiology as well as absence of the necessity to use cement and bone auto- and allografts. Disadvantages include the difficulty for reposition prior to fixation and impossibility of correction in postoperative period as well as early weight-bearing load.

Insensitivity To Pain

Introduction. Congenital insensitivity to pain and anhidrosis (CIPA) or hereditary sensory and autonomic neuropathy type IV is an extremely rare syndrome. Three clinical findings define the syndrome: insensitivity to pain, impossibility to sweat, and mental retardation. This pathology is caused by a genetic mutation in the NTRK1 gene, which encodes a tyrosine receptor (TrkA) for nerve growth factor (NGF).Methods. The consultation of a child female in our center with CIPA and a tibia fracture in pseudoarthrosis encouraged us to carefully review literature and examine the therapeutic possibilities. A thorough review of literature published in Pubmed was done about CIPA and other connected medical issues mentioned in the paper.Conclusions. The therapeutic approach of CIPA remains unclear. The preventive approach remains the only possible treatment of CIPA. We propose two new important concepts in the therapeutic approach for these patients: (1) early surgical treatment for long bone fractures to prevent pseudoarthrosis and to allow early weight bearing, decreasing the risk of further osteopenia, and (2) bisphosphonates to avoid the progression of osteopenia and to reduce the number of consecutive fractures.

Upper Third

Seventeen patients with open fractures of the upper third of the femur were treated using a pelvifemoral external fixation device. All of them had grade III open fractures resulting from high-velocity missile and explosive injuries with massive foreign body contamination. Sciatic nerve injury was present in five (29.4%); abdominal viscera and thoracic wall injuries were present in two patients (11.8%). There were no major arterial injuries. Full weight bearing was allowed after clinical and radiological bone healing (average 11.5 months). Chronic osteitis with fistula and sequestra developed in two (11.8%) patients. There were no nonunions and no refractures. Minor painless limitation of hip motion persisted in all patients. Upper-third femoral open fractures due to firearms are a unique type of open fractures. They are usually highly comminuted ; therefore, stable fixation is difficult or impossible to achieve using external fixation with transfixation of the fracture site. On the other hand, the risk of infection is high following intramedullary nailing. Pelvifemoral external fixation allows adequate management of the soft tissue wounds, provides stable bone fixation and allows early patient mobilization.

Retrograde Femoral Nailing

Comminuted supracondylar femur fractures in the elderly are often treated with either retrograde femoral nailing or locked plating. Early weight-bearing is typically restricted after fixing supracondylar fractures, thereby impairing the patient’s mobilization. In general, surgeons are more comfortable allowing early weight-bearing of long bone fractures after nailing rather than plating, but early studies of retrograde nails for supracondylar fractures using standard distal locking showed poor fixation compared with locked plating.

Quantitative assessment of weight-bearing feet reaction at walking (computer complex DiaSled-Scan, St.Petersberg) was performed in 6 patients with pelvic bone fractures treated by transosseous osteosynthesis using Ilizarov device. In stable fixation of pelvic bones by the device the forefoot was used as additional balance when walking without assistive devices. The decrease in anterior and posterior push range which is compensated by the increase in time during one cycle of gait and its' variability should be considered as a summarizing index of adaptive changes of gait. Compensatory increase up to 40% of stance phase variability on the less involved side is preserved by 1 year after surgery.

Introduction: The objective of this study was to determine the effectiveness and the complications associated with elastic stable intramedullary nailing in long bone fractures in children.Methods: This study was conducted in the Department of Orthopaedic surgery in M. M. Medical College from July 2006 to November 2009. Eighty two patients were recruited from Emergency and out patient department having closed fracture of long bones of upper and lower limbs. All patients were operated under general or spinal anaethesia. All patients were followed for twelve months.Results: All children achieved union in a mean time of 10 weeks (range from 6 - 16 weeks) depending on the type of long bone. Full weight bearing was possible in a mean time of 8.8 weeks. Mean duration of hospital stay was 9.8 days. The mean follow-up period was 28 months (17-48 months). Complications were recorded in 5 (6.09%) patients and included: two entry site skin irritations, one protrusion of the wires through the skin and two delayed union. The results were excellent in 97.310% and good in 2.44% patients.Conclusion: We concluded that this technique is advantageous because of early mobilization (early weight bearing), less complication with good results and is economical.Bangladesh Journal of Medical Science Vol.16(1) 2017 p.61-68

Early Weight Bearing

Early weight bearing appears to enhance bone fracture healing under Ilizarov circular fixators (ICFs). However, the role of early weight bearing in the healing process remains unclear. This study aims to provide insights into the effects of early weight bearing on healing of bone fractures stabilized with ICFs, with the aid of mathematical modeling. A computational model of fracture site was developed using poro-elastic formulation to simulate the transport of mesenchymal stem cells (MSCs), fibroblasts, chondrocytes, osteoblasts, osteogenic growth factor (OGF), and chondrogenic growth factor (CGF) and MSC differentiation during the early stage of healing, under various combinations of fracture gap sizes (GS), ICF wire pretension forces, and axial loads. 1 h of physiologically relevant cyclic axial loading followed by 23 h of rest in the post-inflammation phase (i.e., callus with granulation tissue) was simulated. The results show that physiologically relevant dynamic loading could significantly enhance cell and growth factor concentrations in the fracture site in a time and spatially dependent manner. 1 h cyclic loading (axial load with amplitude, PA, of 200 N at 1 Hz) increased the content of chondrocytes up to 37% (in all zones of callus), CGF up to 28% (in endosteal and periosteal callus) and OGF up to 50% (in endosteal and cortical callus) by the end of the 24 h period simulated. This suggests that the synergistic effect of dynamic loading-induced advective transport and mechanical stimuli due to early weight bearing is likely to enhance secondary healing. Furthermore, the study suggests that relatively higher PA values or lower ICF wire pretension forces or smaller GS could result in increased chondrocyte and GF content within the callus.
