Outcome Measures

Primary Outcomes (3)

  • Functional outcome of the upper limb

    For the participant with bone defect of the upper limb, the Disabilities of the Arm, Shoulder, and Hand (DASH) score will be used to evaluate for the limb functional outcome. The scale is ranging from 0 (no disability) to 100 (most severe disability).

    1 to 12 months

  • Functional outcome of the lower limb

    For the participant with bone defect of the lower limb, the Karlstrom \& Olerud score will be used to evaluate for the limb functional outcome. The scale is graded as: bad, fair, good, excellent functional outcome.

    1 to 12 months

  • Radiological imaging

    the bone healing process is evaluated by the change in dual energy CT-scan result

    Post-operative day 1 to 12 months

Secondary Outcomes (1)

  • Complications

    through study completion, an average of 1 year.

Study Arms (1)

Participants with massive bone defect

EXPERIMENTAL

Adult participants with health insurance regardless of sex having bone defect greater than 5cm due to trauma or tumour resection agree to participate the research. The customised 3D-Printed implant is manufactured and undergoes post-processing treatment before being ready for implantation surgery.

Device: Implantation

Interventions

Reconstructing the long bone defect with 3D-printed customised Titanium alloy implant

Also known as: Bone defect implant
Participants with massive bone defect
