Abstract:
Objective To observe the effect of injectable tissue-engineered bone in treating periarticular bone fracture nonunion under arthroscopy. Methods Selected 6 patients with intra-articular bone fracture nonunion:3 cases of humerus intercondylar fracture;2 cases of femoral condylar fracture and 1 cases of tibial plateau fracture. All of the 6 patients have undergone arthroscopic debridment and tissue-engi-neered bone injection in the the fracture ends with puncture needle under direct vision. Percutaneous needle internal fixation were performed if necessary. All the patients have got regular follow-up after the operation process. Check their healing condition with X-ray examination, and the healing of the bone and its complications have also been monitored. Reexamination were made 3, 6, 9, and 12 months after surgery. Results All the patients have experienced successful operation and all the fracture have healed up. The X-ray review showed that the callus healing time was (8. 34 ± 2. 4) weeks and fracture healing time was (18. 2 ± 3. 3) weeks. Accordong to Johner-Wruhs functional category, there were 5 cases of excellent recovery and 1 case of medium recovery. Among these patients, inflammatory reaction occurred in 1 case, and the symptoms disappeared after 2 weeks of Vancomycin anti-inflammatory treatment; deep venous thrombosis occurred in 1 case, and the symptoms disappeared after systematic anticoagulant therapy. Conclusion It’ s safe and effective to treat periarticular bone fracture nonunion with injectable tissue-engineered bone under arthroscopy.
