BACKGROUND: Cubitus varus is a well-reported complication of supracondylar fracture of the humerus potentially resulting in cosmetic problems, impaired function, and malpractice claims. Traditional methods of correcting malunited distal humeral fractures involve complex osteotomies that have a high complication rate, require a large exposure, and challenging fixation. We present a technique of gradual correction using a percutaneous transverse osteotomy and 3 dimensional correction with a Taylor Spatial Frame...

Pilon fractures are commonly caused by high energy trauma and can result in long-term immobilization of patients. The use of an external fixator i.e. the (1) Delta, (2) Mitkovic or (3) Unilateral frame for treating type III pilon fractures is generally recommended by many experts owing to the stability provided by these constructs. This allows this type of fracture to heal quickly whilst permitting early mobilization. However, the stability of one fixator over the other has not been previously demonstrated...

Intra-articular calcaneal fractures are associated with high morbidity, persistent pain, and long-term disability. This retrospective study assesses early clinical and radiographic postoperative findings of intra-articular calcaneal fractures following treatment by ligamentotaxis using a delta frame construct with a large fragment external fixator. Minimally invasive percutaneous reduction of calcaneal fractures is an alternative treatment for Sanders type II, III, and IV fractures. Ten patients from the Detroit Medical Center were followed between January 2002 and December 2004 for follow-up over a mean of 353...

BACKGROUND: Treatment options for comminuted tibial shaft fractures include plating, intramedullary nailing, and external fixation. No biomechanical comparison between an interlocking tibia nail with external fixation by an Ilizarov frame has been reported to date. In the present study, we compared the fatigue behaviour of Ilizarov frames to interlocking intramedullary nails in a comminuted tibial fracture model under a combined loading of axial compression, bending and torsion. Our goal was to determine the biomechanical characteristics, stability and durability for each device over a clinically relevant three month testing period...

Twenty patients with severely comminuted fractures about the ankle, either severely comminuted pilon fractures or open pilon fractures (three Grade II, seven Grade III), were managed with the use of a Delta-framed external fixator across the ankle joint. All fractures had open reduction and internal fixation (ORIF) with either screw fixation or small plates to stabilize the articular surface with minimal soft-tissue dissection. Average external fixator time was 2.5 months, and the time to union averaged 4.5 months...

The relative stiffness of human tibial fixation by plaster casts, intramedullary rods, external fixators, and dynamic compression plates was compared to the stiffness of the intact tibia. Four-point bending was performed on each specimen, first intact, and then after sequential instrumentation, thus allowing each specimen to serve as its own control. The mean stiffnesses obtained for the bone-device complexes, as a percentage of the intact tibial stiffness, were 113 +/- 9% for the delta frame fixator, 57 +/- 14% for the dynamic compression plate, 28 +/- 2% for the unilateral external fixator (UEF) with stainless steel sidebar, 18 +/- 1% for the UEF with aluminum sidebar, 7 +/- 2% for the flexible intramedullary (IM) rods, and 6 +/- 2% for the cast...

The rigidity, load to yield, and load to failure of ten configurations of the Hoffmann external fixator were investigated using a model of wooden pylons with a simulated fracture that consisted of either a reduced transverse cut or a ten-millimeter gap. The axial compressive, torsional, anterior-posterior bending, and medial-lateral bending characteristics of four forms of the single half-frame (half-pinned), four double half-frame, and two full-frame (transfixion-pinned) configurations were examined. Of the single half-frame configurations, a system with a second stacked connecting-rod proved to be superior; however, the system yielded at a mean axial compressive load of only 199 newtons and failed totally at 355 newtons...

The dynamic ASIF-BM external fixator incorporates telescopic tubes for axial dynamization and angled bayonet screws to keep the tubes parallel to the bone axis, that is essential for gliding, and adjustment of rotation. The results after treatment of 70 type II and III open tibial fractures with static ASIF and dynamic ASIF-BM frames were analysed. Of the fractures, 32 were treated with the delta ASIF static frame, the other 38 with delta and uniplanar dynamic ASIF-BM frames. The groups were found to be comparable...
