Introduction: Orbital hypertelorism (HTO) is a challenging craniofacial problem seen in association with some congenital deformities. The age of HTO correction is a matter of debate.
The Aim Of The Work: to evaluate the outcome of HTO correction and determine the optimal timing for intervention, striving for the earliest possible intervention with the lowest relapse.
Patients And Methods: A standard craniofacial approach with medial bone resection, 4 walls orbital box osteotomy and orbital medialization were done for all patients. Skeletal and soft tissue procedures were done as indicated.
Results: there were 10 patients aging 6 to 19 years. Seven were associated with craniofacial clefts, and 3 with craniosynostosis syndromes. HTO was severe in 8 cases and moderate in 2 cases. It was asymmetric in 2 cases. Frontoorbital remodeling was done in 3 cases with craniosynostosis. Failed surgery was reported in 2 cases. A redo surgery was done for one of them with an excellent outcome, while refused by the other. Nine patients had an excellent outcome. The mean level of satisfaction was 93.37%. Three patients had ugly facial scars. No major complications were recorded.
Conclusion: The time for surgical treatment of HTO is determined by the severity of the associated deformity. If there is an urgent factor indicating intervention, early correction can be performed exceptionally; otherwise, HTO correction should be performed after the age of 6 years.

Article Synopsis
- Knee pain often involves varus deformity and unicompartmental osteoarthritis, where high tibial valgus osteotomy (HTO) has emerged as an effective treatment option to delay joint replacement.
- A case report highlighted two patients with bilateral knee arthritis who underwent medial opening-wedge high tibial osteotomy using Dr. Saigal's plate, both achieving good range of motion and minimal complications post-surgery.
- Comprehensive evaluations, including radiological assessments and specific surgical techniques like the Miniaci Method, were employed to ensure successful outcomes, with both patients showing significant improvement after one year.

Introduction: High tibial osteotomy (HTO) is indicated for managing isolated medial knee osteoarthritis in a young patient with a metaphyseal deformity of the proximal tibia. In a medial open-wedge HTO, maintaining the integrity of the hinge is crucial for consolidation and preservation of the correction. Based on a validated model and preliminary results, the objective of this work was to measure and monitor the distribution of mechanical load on a locking fixation plate and the lateral hinge of an HTO using a finite element (FE) model during different phases of consolidation evolution, simulating single leg weightbearing.

: Although hybrid closed-wedge high tibial osteotomy (HTO) is an effective procedure for varus knee osteoarthritis, delayed bone union is a frequent occurrence. The rate of bone union and its associated factors remain unclear. This study aimed to investigate the detailed process of bone union in hybrid closed-wedge HTO using computed tomography (CT) and to examine factors associated with delayed bone union.

Purpose: To compare the clinical and radiographic outcomes and complications between medial opening wedge (MOW) and lateral closing wedge (LCW) high tibial osteotomies (HTOs) in the setting of medial compartment osteoarthritis with genu varus alignment.
Methods: This study was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Studies that reported on MOW or LCW HTOs in the setting of medial compartment osteoarthritis were included.

Objective: To systematically review the clinical efficacy and safety of high tibial osteotomy (HTO) combined with platelet-rich plasma (PRP) for treating knee osteoarthritis (KOA) and to provide evidence of the effectiveness of evidence-based medicine for treating this disease.
Methods: Clinical studies on the use of HTO combined with PRP for the treatment of KOA before September 2024 were identified. The literature that met the inclusion criteria was strictly screened out, the literature information was extracted, and the data were input into RevMan5.
