Brief Summary:

This research is aimed to evaluate the combination of mesenchymal stem cell, HA-CaSO4, BMP-2, and implant in treating critical-sized bone defect.

In the presence of critical-sized bone defect whose defect size is more than 2.5 cm, bone will suffer a healing disturbance. In treating these conditions, the conventional method were vascularised bone grafting and bone transport. But the existing methods of treatment have many weaknesses Vascularized bone graft is a procedure with a high level of difficulty. Hence not every orthopaedic surgeon were able to perform it. It also takes more operating time and its failure rate is also quite high.

Meanwhile, external fixation which is applied with bone transport, was being often complained by the patient in terms of cosmetic and psychologically.

According to diamond concept of bone healing, there are four main factors that influence the bone healing. These factors are osteogenic factor (mesenchymal stem cell), osteconductive factor (HA-CaSO4), osteoinductive factor (bone morphogenetic protein-2) and mechanical component (implant). The potency of each component in fracture healing with/out bone defect has been proved in many studies. The combined effect of these components is often studied as well, but not in critical-sized bone defect.

Union Drug: Mesenchymal stem cell, HA-CaSO4, ¬BMP-2, and Implant Phase 1

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 5 participants
Intervention Model: Single Group Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Study Start Date : November 2012
Estimated Primary Completion Date : December 2014
Estimated Study Completion Date : December 2014

Arm Intervention/treatment
Experimental: Stemcell
Mesenchymal stem cell, HA-CaSO4, ¬BMP-2, and Implant
Drug: Mesenchymal stem cell, HA-CaSO4, ¬BMP-2, and Implant

Primary Outcome Measures :
  1. RADIOGRAPHIC UNION SCALE (RUST Score) as a measure of bone union [ Time Frame: Before surgery, after surgery, week 4 , 8, 12, 16, 20, 24 up to 1.5 years ]
    plain radiograps will be taken to determine whether the bone has healed.

Secondary Outcome Measures :
  1. Visual analog scale as the measure of clinical union [ Time Frame: Before surgery, after surgery, week 4 , 8, 12, 16, 20, 24 up to 1.5 years ]
    We will measure VAS (grade 0-10) to determine the clinical union
