Abstract
The Taylor Spatial Frame is a new external ring fixation system for correction of multi-planar deformities of the extremities. We report the first 100 consecutive cases treated with this system at the Bristol Limb Reconstruction Unit from November 1999.
The Taylor Spatial Frame incorporates the technology of a virtual hinge and a Stewart Gough Platform. With the use of computer software it is capable of adjustments to within 1 degree and 0.5mm accuracy. Deformities are measured on plain radiographs. Required corrections over any period of time are calculated and a printed prescriptiion of daily adjustments is given to the patients to perform themselves at home.
The following conditions were treated: Non-union (44), malunion (16), Leg length discrepancy (14), limb deformity (13), and acute fractures (13). The aims of frame treatment were non-union treatment (28), bone transport (12), acute fracture healing (12), correction of deformity (28), leg lengthening (15), and arthrodesis (5). Most cases involved the tibia (77) but the frame was also used on the femur (13), knee (3), ankle (4), humerus (2), and forearm (1).
Complete correction of deformity was achieved in all but 7 patients. Union was achieved in 99 cases. All non unions united without bone graft. Mean transport of 46mm and lengthening of 38mm was achieved. 1 arthrodesis failed to unite. All fractures united without any residual deformity. Mean treatment time was 169 days (range 43 to 401). There was 100% compliance with patients performing adjustments themselves. Minor pin site problems were common (34 patients) but only 3 required debridement. Other problems included wire breakage (10), pain (3), peroneal nerve palsy (1) and DVT (1). 15 knees and 11 ankles developed stiffness which resolved.
This study demonstrates the role of the Taylor Spatial Frame as an extremely versatile, accurate and safe new tool at the orthopaedic surgeon’s disposal in limb reconstruction and trauma surgery.
