Article Abstract
Background/aim: We have designed an adjustable bone plate (ABP) which allows bone shortening and lengthening after fixation, which is a property not present in any of the plate systems available today. The aim of the current study was to examine the new ABP's segmental bone transfer capability for the treatment of a segmental bone defect in an animal model.
Materials And Methods: Five sheep had ABPs attached to 10 of their tibias and bone defects of 15 mm in size were created. The pinion mechanism was moved with a manual screwdriver at a rate of 1mm/day for 15 days starting 3 days postoperatively. The animals were euthanized 3 months postoperatively, and the defect site and the transferred segment were evaluated by radiological and histological examination.
Results: The radiological results revealed successful transfers of 14.6 ± 1.2 mm of bone segment on all tibia defects without any complications. The histological evaluation showed new bone formation in both the extension and the docking sites. No rupture or breakage was observed within the plates.
Conclusion: We have presented the potential of a new generation ABP for use in segmental bone transfer in an animal model as well as for future clinical applications.

The cervicothoracic junction (CTJ) presents a surgical challenge due to its transitional nature from mobile to rigid segments. Therefore, the biomechanical characteristics of this transitional zone must be taken into consideration during instrumentation. This study aimed to determine the efficacy of the cervical pedicle screw placement (CPS) combined with 5.

ObjectiveTo determine the effectiveness of bilateral decompression combined with a unilateral transforaminal lumbar interbody fusion approach in centralizing a lordotic cage and preventing contralateral radiculopathy by ensuring equal foraminal elevation.MethodsThis is a retrospective cohort study based on clinical records and radiological data. Eighty-seven patients diagnosed with lumbar spinal stenosis at L3-S1 levels underwent bilateral decompression and transforaminal lumbar interbody fusion between 2017 and 2022.

Reconstructing multi-tissue defects in the finger remains a significant challenge in hand surgery. We present the case of a 37-year-old man with segmental loss of bone, skin and extensor apparatus on the dorsal aspect of the index finger. A single stage reconstruction was successfully performed using a pedicled chimeric flap based on the second dorsal metacarpal artery combining skin paddle, second metacarpal base bone and the extensor indicis proprius.

Objective: We developed and validated an artificial intelligence pipeline that leverages diffusion models to enhance prognostic assessment of knee osteoarthritis (OA) by analyzing longitudinal changes in patella shape on lateral knee radiographs.
Method: In this retrospective study of 2,913 participants from the Multicenter Osteoarthritis Study, left-knee weight-bearing lateral radiographs obtained at baseline and 60 months were analyzed. Our pipeline commences with an automatic segmentation for patella shapes, followed by a diffusion model to predict patella shape trajectories over 60 months.
Spontaneous Bone Regeneration ("Phoenix Jaw" Phenomenon) Following Segmental Mandibulectomy for Stage 3 Medication-Related Osteonecrosis of the Jaw: A Case Report.

Segmental mandibulectomy is a valid treatment for advanced medication-related osteonecrosis of the jaw (MRONJ), but subsequent reconstruction is challenging. Spontaneous bone regeneration (SBR) following resection is exceedingly rare, particularly in the elderly. We present the case of a 63-year-old woman with stage 3 MRONJ who underwent a 60 mm segmental mandibulectomy.
