NCT02901782

Brief Summary

Microwave ablation of bone tumors is time-consuming and usually results in postoperative fractures. Hence the investigators designed and fabricated a titanium plate customized to the patient's bone structures for fixation after the removal of tumorous tissue, to improve the clinical outcomes of microwave ablation.

Outcome Measures

Primary Outcomes (3)

  • Musculoskeletal Tumor Society score

    An average of 29 months

  • Mean maximum flexion of the knee

    An average of 29 months

  • The six degrees of freedom of the gait

    including flexion/extension, adduction/abduction, internal/external rotation, anteroposterior translation, distal/lateral translation, medial/lateral translation

    An average of 29 months

Secondary Outcomes (1)

  • Mean operation time

    Time when the operation was begun

Study Arms (1)

Personalized titanium plate

EXPERIMENTAL

Ten males and two females with a mean age of 22.8 years were recruited. They all had bone tumor around the knee.

Procedure: Personalized titanium plate

Interventions

3D models of tumor-bearing bone segments were constructed by using computed tomography (CT) and magnetic resonance imaging (MRI). The 3D models were used to design the model of personalized titanium plates. The model of the plates was transferred into a numerical control machine for manufacturing the personalized titanium plates by 3D printing technology. The plates were then surgically implanted for reconstruction assistance following microwave-induced hyperthermia to remove the bone tumor. Implementation parameters and knee function were then evaluated.

Eligibility Criteria

Age5 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Clinical diagnosis of primary malignant bone tumors in the distal femur or proximal tibia according to the preoperative biopsy.
  • Malignant soft tissue tumor invading distal femur or proximal tibia.
  • The patients have the opportunity of limb salvage and treatment of microwave-induced hyperthermia in situ and reconstruction with internal fixation.

You may not qualify if:

  • Distant metastasis.
  • Benign tumor.
  • Metastatic tumor around the knee.
  • No indication of limb salvage.
  • Malignant soft tissue tumor without bone invasion.
  • Recrudescent tumors.
