METS Modular Implants

Minimally Invasive Extendible Prosthesis

This device is not yet cleared for sale in the USA.

Minimally invasive implants are a good option for patients reaching skeletal maturity especially if the resection is relatively small.

Minimally Invasive Extendible Prosthesis photoWith its smaller volume, the minimally invasive JTS is suited to the proximal humerus and proximal tibia.

A hexagonal key is used to telescopically extend the implant during a short session of minimally invasive surgery via a 1 to 2 cm stab incision. The implant is typically lengthened by 5 6mm at each session.

Once skeletal maturity has been achieved the implant is retained in situ.

Advantages of the minimally invasive JTS implant:
  • Minimal implant bulk assists soft tissue closure
  • Accurately controllable lengthening
  • Reversible
  • High proportion of extension is obtainable as a proportion of the resected length / total implant length
  • Patient Specific made device for a precision fit
  • Implant remains in situ when maximum extension is achieved
  • Malignant tumours arising in bone
  • Patients with significant leg length discrepancies who had previously undergone limb sparing surgery
