Purpose:
Rickets is a condition characterized by a defective mineralization on the epiphyseal plate, either in the form of nutritional or congenital hypophosphatemic rickets, which could lead to progressive bone deformity. One of said deformities is angular growth of the knee which can cause permanent disfigurement. Hemiepiphysiodesis is a surgical option to correct the deformity, yet the studies evaluating its results are rare. This review aimed to map the literature pertaining to this topic.
Methods:
A comprehensive search was performed across five databases: Pubmed, Cochrane, ProQuest, Embase, and Science Direct to identify studies involving children with rickets treated with hemiepiphysiodesis. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Tool, and the outcome data were compiled.
Results:
Six studies fulfilled the inclusion and exclusion criteria of this study with highly varied groupings and outcomes. However, the risk of bias of all studies was low to moderate. Hemiepiphysiodesis showed good outcome in function, radiological parameter, and correction rate with lower complication rate compared to osteotomy. The average time required to achieve full deformity correction was within 10.8-22.7 months. However, hemiepiphysiodesis has a risk of overshooting the correction or paradoxically rebounding to the prior condition, therefore, requiring routine follow-up.
Conclusion:
Hemiepiphysiodesis is beneficial for the correction of angular deformities in the knee due to rickets.
Significant Of Studies:
This review provides a crucial evidence base for clinicians by establishing hemiepiphysiodesis as a viable, less invasive alternative to osteotomy.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
