We report a case of an 11-year-old girl with bilateral severe Madelung deformity who underwent radial osteotomy with callus distraction. The distal radial articulation was corrected at surgery, and a unilateral fixator was subsequently used for callus distraction. No postoperative complication was noted. The patient did not need any additional surgeries for correction of the deformity. Forty-three months after surgery, the patient had a nearly full range of motion without any pain. Forearm deformity was not noticeable, except for surgical scar on both wrists.

Objective: This study aimed to assess the effect of implantation of fresh human amniotic membranes (HAM) on bone consolidation during distraction bone lengthening.
Methods: Ten New Zealand white rabbits were used in this study. For each rabbit, we performed a diaphyseal tibial osteotomy after installing a single-plane distraction external fixator.

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).

Distraction osteogenesis (DO) is widely utilized for treating limb length discrepancy, nonunion, bone deformities and defects. This study sought to develop a 4D time-lapse morphometry method to quantify bone formation and resorption in mouse femur during DO based on image registration of longitudinal in vivo micro-CT scans. Female C57BL/6 mice (n = 7) underwent osteotomy, followed by 5 days of latency, 10 days of distraction and 35 days of consolidation.

Objective: Bone incision leads to interrupted and sluggish blood flow in the process of distraction osteogenesis (DO), creating a hypoxia (0-2% oxygen tension) at the center of the bone callus. This hypoxia is critical in the coupling of osteogenesis and angiogenesis during DO. This study aimed to investigate the effect of Uniaxial Static Strain (USS) on osteogenesis in osteoblasts under hypoxic conditions, with a focus on the expression of osteogenic markers and angiogenic factors.

Distraction osteogenesis (DO) is a valuable surgical method for limb lengthening and bone defect correction, but its lengthy consolidation phase presents challenges. The accordion technique (AT), involving compression and distraction of bone segments, has shown potential for enhancing healing. This study aimed to investigate the effectiveness of the AT conducted at three different time points (distraction phase, early consolidation phase, or late consolidation phase) compared to conventional DO in a mouse osteotomy model.
