Read the full statement (166 words)
The Cannulated NuGenTM FX Screw is generally intended for maintenance of alignment and fixation of fractures, osteotomies, arthrodeses or condylar grafts within the condylar aspects of the upper extremity, ankle and foot, in the presence of appropriate brace and/or immobilization. Specifically, it is intended for phalangeal fusion and fracture, metacarpal fusion and fracture, carpal fusion and fracture, wrist arthrodesis, Distal radius fractures, olecranon fractures, radial head fractures, humeral condylar fractures, cancellous fractures and osteotomies of the malleolus, ankle fractures, metatarsal osteotomies and correction of hallux valgus.
The Cannulated NuGenTM FX Screw is not intended for use in and is contraindicated for: 1) Fractures and osteotomies of cortical bone (except those in the hand and foot) and proximal femoral fractures. 2) Situations where internal fixation is otherwise contraindicated, e.g.. active or potential infection and where patient co-operation cannot be guaranteed (e.g. alcoholism). 3) Highly comminuted fractures, which would not be appropriate for fixation with metallic screws. 4) Patients with suspected or known allergy to the implant material.
Indications for use as stated in the FDA summary.
