INTRODUCTION Rolando fractures are often difficult to manage because of their inherent instability. We describe a simple technique for the treatment of this fracture using the principle of ligamentotaxis, with a static, two-pin external fixator spanning the trapeziometacarpal joint, and present the results of a single-surgeon case series. METHODS Eight consecutive patients (mean age: 32.8 years) with Rolando fractures were treated using a Hoffmann II® Micro small bone external fixator using blunt ended 2.0mm half pins, inserted into the trapezium and diaphysis of the first metacarpal. Functional outcome was assessed with the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score at a mean time of 2.7 years following the fracture (range: 4 months – 6.0 years). The mean time to frame removal was 28 days. RESULTS There were three cases of superficial pin site infection. Follow-up x-rays at four months did not demonstrate significant joint incongruity or malunion in any case. The mean QuickDASH score was 7.95 and all patients returned to their previous levels of activity. CONCLUSIONS Although external fixation risks pin site infection, the results of this study support the use of spanning trapeziometacarpal external fixation for Rolando fractures as it reliably gives excellent functional outcomes.

Pin tract inflammation and/or infection are common with the use of external fixation devices. Pin sites need to be managed to help prevent complications. There are a variety of regimens proposed for pin care in the literature. The authors present an efficient and simplified approach for addressing pin care protocol using cord locks with the use of compression sponges for external fixation devices. This method obviates the need for extensive bandaging and makes pin care easy for the patient to carry out. A brief review of the current evidence on pin care is presented, and an evidence-based pin care protocol is presented. Level of Evidence: Therapeutic, Level V

Type Of Fracture

Twenty-two patients had a severe open fracture of the tibia that was initially treated by external fixation and subsequently by locking plate. The external fixation had been maintained for an average of fifty-nine days (range, 15 to 240 days). The mean interval between removal of the external fixator and plating was twenty-six days (range, 10 to 44 days). five out of twelve patients who had an infection at one or more of the pin sites, developed one superficial and four deep infection. In comparison, only one of the ten patients who had not had a pin-site infection had a superficial infection. An analysis of other variables, including the duration of external fixation, wound coverage, other injuries, and the type of fracture, showed that none was a predictor of infection either at the pin sites or around the plate. We concluded that a pin-site infection that develops during external fixation is a contraindication to the subsequent plating in patients who have a fracture of the tibia.

A special place in the methods of surgical treatment of bone fractures is occupied by transosseous osteosynthesis using external fixation devices of various designs.Objective: to analyze the lower jaw exoskeleton in finite element programs.Materials and research methods. During the research, 36 human lower jaws were involved from the museum of the Department of Oper-ative Surgery and Topographic Anatomy of the Volgograd State Medical University. They were scanned in 3D. All obtained images were loaded into a virtual scene reconstruction program. Fractures of the lower jaws in the corner area were modeled, an apparatus for external fixation of the lower jaw exoskeleton was installed, and the chewing load on the lower jaw was simulated. The place of application of the force was an area on a small fragment of a repositioned 3D model of the mandibular bone corresponding to the place of attachment of the masseter muscle. The evaluation of virtual studies was carried out according to the results of the stress-strain states of the bones and apparatus, the schedule of displacements of objects and the results of the analysis of the safety factor.Research results and discussion. In the course of evaluating the virtual placement of the mini-fixator wires of the apparatus for external fixation of the lower jaw exoskeleton, it was revealed that the main load is applied to the mini-fixator wires on a large fragment and the bone in the area of the wires. For the possibility of precise positioning of the osteofixers of the external fixation device, a device for the safe installation of the spokes of the lower jaw exoskeleton was also developed.Conclusion. Thus, on the basis of computer mathematical analysis, it can be argued that the developed design of the apparatus for external fixation of the lower jaw exoskeleton works under conditions of the maxillofacial region, performs reposition and fixation of bone fragments of the lower jaw under conditions of chewing functioning of the restored fracture of the lower jaw.
