The Sheffield hybrid fixator — a clinical and biomechanical review

Sequential reconstruction of complex femoral fractures with circular hybrid Sheffield frame in polytrauma patients

“…Farrar et al [8] described the use of external fixation in severe fractures of various long bones. In their series of 43 patients, Zlowodzki et al [22] reported [12] showed that HA-coated pins have significant antimicrobial actions, optimal bone pin contact, and no deterioration of the bone-pin interface.…”

“…TSF is more cumbersome than the conventional Ilizarov frame, and the financial cost is comparatively high [7]. Farrar et al reviewed their first 100 cases with the Sheffield Hybrid Fixator (SHF), most in the tibia, only 2% in the distal femur [8]. They had satisfactory results.…”

Knee arthrodesis with the Sheffield external ring fixator: Fusion in 6 of 10 consecutive patients

“…Also, reduced bone quality in the femur compared to the tibia could possibly have delayed fusion in the 2 non-fusion patients with no infected tracts. Inferior femoral stability might be overcome and improved by applying an extra fixation bar, more femoral ring screws, or an additional proximal ring (Farrar et al 2001). Also, secondary bone grafting, a prolonged fixation period, and further compression or callus distraction can be considered when signs of clinical and radiological fusion are not present (Knutson et al 1985, Rand 1993.…”

Why fine-wire fixators work: An analysis of pressure distribution at the wire–bone interface

“…Wires are also available with olives or stoppers about one third along their length so that bone fragments can be compressed. The uses for these systems is still expanding (Farrar et al, 2001;Saleh et al, 1999) with recent reports including arthrodesis of the knee and foot (Oostenbroek and van Roermund, 2001;Weber et al, 2002), the treatment on Blount's disease and Madelung deformity (Accadbled et al, 2003;Schroder et al, 2003). The alternative to tensioned fine wires is the use of so-called half pins.…”
