The Thermal Effects of Kirschner Wire Fixation on Small Bones

The aim of this study was to assess bone heating caused by the passage of fine (<2 mm) K-wires of different types. Stainless steel K-wires of trocar and diamond point configurations (0.8–2.0 mm) were drilled into the metatarsal bones from a freshly amputated lower limb at a constant force. Temperature measurements were made by miniature thermocouples inserted into the bones, at 3 second intervals over a period of 3 minutes while each K-wire was drilled three times. The temperature reached varied with the tip configurations and the diameter of the K-wires. Regardless of point configuration, thinner wires generated more heat than thicker ones.

We have studied the biomechanical stability in vitro of three different Kirschner (K) wire configurations in three types of simulated scaphoid waist fractures. The fractures were created with a saw in Sawbones models. There were three fracture patterns: perpendicular to the long axis of the scaphoid model; and 30° and 20° oblique to that. Two 1.2 mm. K-wires were used in each scaphoid. The three configurations were: parallel; 20° oblique; and crossing. The oblique or crossing configurations of K-wires were the most stable depending on the fracture pattern.

Introduction: The majority of fractures of the metacarpal bones occur at a young age.Most of thetimes these metacarpal fractures can be treated conservatively in a POP slab(cock up slab)producing good functional results.Surgery was indicated in patients with palmar dislocation of >30°and shortening of >5 mm.Our study aimed to evaluate the clinical results of all metacarpal fracturestreated surgically by intramedullary Kirschner-wire fixation presented in our hospital.Materials andMethods: It was a retrospective study in which we included 50 patients with metacarpalfractures(both open andclosed) that came in our hospital, treated surgically by closed reduction andwere fixed with two intramedullary k-wires. Result: K-wires were removed after 4 weekspostoperatively,under local anaesthesia in the OPD. Metacarpal joint functions (flexion, extension,rotation) were clinically followed up in all patients, on the median periodof6 months (3 months to 9months). In our study, we found in all patients,flexion and extension were normal on bothsides.Conclusion: Closed reduction and intramedullary k-wire fixation of metacarpal bone fracturesproduce good functional results in the longterm. We found a very low rate of complication and thusrecommendthis surgical method for the stabilization of all these types of fractures.

Objectives: To know the functional outcome of Intramedullary Kirschner Wire fixation of unstable Radius-Ulna fractures in children. Study Design: Descriptive study. Period: 27/03/2009 to 26/03/2010. Setting: Department of Orthopedic and Trauma, Khyber Teaching Hospital, Peshawar. Patients and Methods: All patients were admitted from OPD . Children less than 16 years with Unstable Radius- Ulna fractures were included in the study. Patients with open fractures and adults with polytrauma were excluded from the study. Unstable Radius-Ulna fractures were treated by Intramedullary Kirschner Wire fixation under general anesthesia and tourniquet control. Follow up till radiological and clinical union was done. K-wires were removed after healing of fractures. Patients were assessed functionally and radiologically and results were graded according to Price et al Criteria. Results: A total of 64 children with unstable radius and ulna fractures were included in the study. The age range was 6 to 15 years with average age of 10.41 years. 47 were male and 17 were female. The average time of radiological union was 7 weeks and K-wires were removed at 8 weeks time. At final assessment there were 47 Excellent, 10 Good and 7 Fair results. Conclusions: Excellent results can be achieved by Intramedullary K-Wires fixation. In children with unstable Radius-Ulna fractures. It should be the method of choice for treating these fractures.

Background: Supracondylar fractures of the humerus are the most common fracture pattern of the elbow in children. Displaced supracondylar fractures are notorious for difficulty in reduction, maintenance of reduction and frequent involvement of neurovascular structures. The purpose of this study was to evaluate the results of stabilization of these fractures by closed reduction and percutaneous Kirschner wire fixation.Methods: Thirty cases of displaced supracondylar humerus fractures were included in the study. The mean age of the patient was 8.3 years [ranges from 4-14 years]. The male to female ratio was 2:1 and left side was involved in 23 cases whereas 7 had right sided injuries. All fractures were of extension type [Gartland’s type III]. Posteromedial displacement was noted in 22 cases whereas 8 fractures were posterolaterally displaced. In 20 cases, lateral entry wires alone were used whereas in 10 cases one lateral and one medial K-wire were used. K- wires were removed after 3 weeks post-operatively and follow-up was done at 6 weeks,12 weeks, 6 months and 12 months, when they were evaluated according to Flynn’s criteria.Results: Results were graded using Flynn’s criteria. Excellent results were achieved in 18 [60%], good in 6 [20%] fair in 4 [13.3%], while poor results were seen in 2 [6.7%] patients.Conclusions: Closed reduction and percutaneous fixation using Kirschner wires is a safe and efficient method for fixation of displaced supracondylar fractures of the humerus in children.
