PANTA® / PANTA® XL
Limit uncertainty with…
PANTA® design rationale
Talo-tibio-calcaneal arthrodesis is a challenging technique. The use of a retrograde nail is part of the therapeutic option that achieves :
- Realignment of the foot on the weight-bearing axis.
- Correction of coronal and saggital plane deformities.
- Rotational stability.
- Axial compression.
The Panta® nail system meets these targets by means of :
- Precise and radiolucent instrumentation.
- A unique system to apply compression balanced with multi-planar screw fixation — in the tibia, the talus and the calcaneus — and enhanced calcaneal fixation to optimise stability and alignment of the arthrodesis.
PANTA® XL design rationale
Longer lengths and a conical extremity shape designed to reduce stress at the proximal tip of the nail have been incorporated. Nail autodynamisation is an added benefit. The proximal edge of the slot maintains compression while allowing dynamisation with postoperative weight bearing, providing continuous compression.
PANTA® and PANTA® XL nails are intended for use in tibiotalocalcaneal arthrodesis and treatment of trauma to the hindfoot and distal tibia. Depending on the particular patient factors, indications may include :
- Post-traumatic and degenerative arthritis involving both ankle and subtalar joints.
- Rheumatoid arthritis.
- Revision of failed ankle arthrodesis with subtalar involvement or with insufficient talar body.
- Revision of failed total ankle arthroplasty with subtalar intrusion.
- Talar deficiency conditions (requiring a tibiocalcaneal arthrodesis).
- Avascular necrosis of the talus.
- Neuroarthropathy or neuropathic ankle deformity.
- Severe deformity as a result of talipes equinovarus, cerebral vascular accident, paralysis or other neuromuscular disease.
- Severe pilon fractures with trauma to the subtalar joint.
The implant should not be used in a patient who has currently, or who has a history of :
- intact asymptomatic subtalar joint
- active local or systemic infection
- severe peripheral vascular disease
- severe longitudinal deformity
- insufficient quantity or quality of bone to permit stabilization of the arthrodesis
- obliterated medullary canal or other conditions which tend to retard healing suchas blood supply limitations, previous infections…
- conditions that restrict the patient’s ability or willingness to follow postoperativeinstructions during the healing process
- insufficient plantar pad
- suspected or documented metal allergy or intolerance.
