AI Article Synopsis
- Patients with cleft lip and palate often experience midface hypoplasia, traditionally treated with orthognathic surgery, which has issues with relapse; this study investigates maxillary distraction osteogenesis using a rigid external device (RED) as a potentially more stable alternative.
- Nine patients underwent maxillary advancement following a specific surgical procedure, with outcomes assessed through imaging at three stages: before distraction, immediately after, and one year later.
- Results indicated a successful average midface advancement of 13.4 mm with stable bone formation and no significant complications, suggesting the RED technique is an effective option for improving maxillary positioning over time.
Article Abstract
Background: Patients with operated cleft lip and palate present with a problem of midface hypoplasia, and such patients have been traditionally treated with orthognathic surgery. Such a procedure has its own limitations of relapse and hence a newer modality of distraction osteogenesis with histiogenesis can be chosen to overcome such limitations for midfacial advancement. The purpose of this study is to evaluate an alternative technique and its postoperative stability in maxillary distraction osteogenesis in patients of cleft lip and cleft palate using a rigid external device (RED).
Method: Nine patients with midface bone stock deficiency were selected for maxillary advancement. At the first surgery under general anesthesia, after Le Fort I osteotomy, RED system was used with the alternative technique. After distraction, evaluation was done for ease of the procedure, stability, and complications. Lateral cephalograms were evaluated at 3 stages: T1, pre-distraction; T2, post-distraction; and T3, 1 year post-distraction.
Results: A mean 13.4-mm midface advancement was shown with bone formation at the pterygomaxillary region without losing the vector and having a standby mode in case the wire broke during distraction The results were stable even at 1 year of follow-up.
Conclusion: Maxillary position improved in relation to the cranial base. This study showed that the RED was versatile in midface advancement.

Department of Pediatric Orthopaedics, Children's Hospital of Fudan University, National Children's Medical Center, 399 Wanyuan Rd, Minhang District, Shanghai, 201102, China.
Purpose: Ollier's disease (multiple enchondromatosis) can cause severe lower limb length discrepancy and deformity in children. Osteotomy and limb lengthening with external fixation can correct the lower extremity deformity. There may be lesions in the osteotomy part (OP), and the internal fixation part of the external fixation(FP).

Article Synopsis
- The prolonged use of external fixation during distraction osteogenesis (DO) can heighten complications, while bone marrow mesenchymal stem cells (BMSCs) play a crucial role in bone regeneration due to their pro-angiogenic and osteogenic abilities.
- RSC-96, a type of Schwann cell, has been shown to promote the proliferation, migration, and differentiation of BMSCs when co-cultured, enhancing both bone formation and blood vessel development through neurotrophic factor secretion and activation of specific signaling pathways.
- In a rat DO model, RSC-96's conditioned medium improved bone healing outcomes, with notable increases in gene expression markers for osteogenesis and angiogenesis, alongside positive radiological and biomechanical assessments.

Background: The purpose of this study was to report the clinical and psychological outcomes of using a locking compression plate (LCP) as a sequential external fixator following the distraction phase in the treatment of tibial bone defects caused by fracture-related infection (FRI).
Methods: We retrospectively analyzed the clinical records and consecutive X-ray images of patients with tibial bone defects who were treated with an LCP as a sequential external fixator following the distraction phase, between June 2017 and December 2022. The ASAMI criteria were applied to assess the bone and functional outcomes, and postoperative complications were evaluated by using the Paley classification.

Introduction: Posterior vault distraction osteogenesis (PVDO) allows significant increase in intracranial volume but is associated with complications including cerebrospinal fluid (CSF) leaks, infection and device failure. The authors outline their outcomes over 12 years and the impact of PVDO on pre-existing Chiari malformation type 1 (CM).
Method: Retrospective review of all PVDOs in our unit over a period of 12 years from 2011 to 2023.
