Longitudinal epiphyseal bracket or bracket epiphysis is an uncommon disorder of growth. Alternatively known as a delta phalanx, it is due to an anomalous secondary ossification center that extends longitudinally along the diaphysis. Although rare, longitudinal epiphyseal bracket most commonly manifests in the hands as clinodactyly and in the feet as hallux varus. Previously, longitudinal epiphyseal bracket has been treated with angular osteotomy, but we recommend early surgical physiolysis. We describe this uncommon disorder, our current recommendation for treatment, and present three illustrative cases.

Radial longitudinal deficiency III and IV present as a short upper limb, functional elbow, and wrist with severe radial and palmar angulation, where the carpus articulates with the radial and palmar edge of the ulna, allowing limited mobility in a nonfunctional position. Surgical treatment aims to correct radial angulation and flexed carpal position, often altering carpal positioning over the distal ulna and impacting wrist mobility. In addition, fixation through distal ulnar epiphysis affects its growth.

The growth plate is the primary site of longitudinal bone growth with chondrocytes playing a pivotal role in endochondral bone development. Chondrocytes undergo a series of differentiation steps, resulting in the formation of a unique hierarchical columnar structure comprising round, proliferating, pre-hypertrophic, and hypertrophic chondrocytes. Pre-hypertrophic chondrocytes, which exist in the transitional stage between proliferating and hypertrophic stages, are a critical cell population in the growth plate.

Purpose: Appendicular skeleton markers are commonly used for maturity assessment for Adolescent Idiopathic Scoliosis (AIS) patients. Traditionally, Risser has been a standard skeletal maturity assessment method. More recently, Sanders classification (SSMS), as a more comprehensive system, became popular, especially in decision-making for Vertebral Body Tethering (VBT).

Enchondromas are a common tumor in bone that can occur as multiple lesions in enchondromatosis, which is associated with deformity of the affected bone. These lesions harbor somatic mutations in IDH and driving expression of a mutant Idh1 in Col2 expressing cells in mice causes an enchondromatosis phenotype. Here we compared growth plates from E18.

Height gains result from longitudinal bone growth, which is largely dependent on chondrocyte differentiation and proliferation within the growth plates of long bones. The growth plate, that is, the epiphyseal plate, is divided into resting, proliferative, and hypertrophic zones according to chondrocyte characteristics. The differentiation potential of progenitor cells in the resting zone, continuous capacity for chondrocyte differentiation and proliferation within the proliferative zone, timely replacement by osteocytes, and calcification in the hypertrophic zone are the 3 main factors controlling longitudinal bone growth.
