The name of the condition indicates that it affects bones of the spine (spondylo-) and the ends of bones (
epiphyses), and that it is present from birth (congenital).
The radiographs of the patients show the abnormal vertebrae instead of normal rectangular shape and parts of the long bones (
epiphyses) of the leg are larger when compared to normal bone.
Chondroblastoma: It is a rare lesion comprising 1% of all primary bone tumours, commonly occurring at
epiphyses or apophyses of long tubular bones (distal femur, proximal humerus and tibia).16 Typically it presents in patients 10-25 years old with male predominance (2:1).16 Patient frequently complains of progressive pain at the site of the lesion.
2 and 3): (1) crania, (2) mandibles, (3) scapulae, (4) long bone diaphyses, (5) vertebrae, (6) ribs, (7) metapodials, and (8) smaller elements (carpals, tarsals, phalanges, and long bone
epiphyses).
The correlation of age with the ossification status of bilateral medial clavicular
epiphyses was determined for both sexes.
The typical clinical manifestations and radiographic findings are progressive deformities, bone pain, stiffness and swelling of multiple joints with the absence of systemic or synovial inflammation, especially in the hips, knees, wrists and fingers, a limitation of motion, short stature, widened
epiphyses, vertebral flattening, narrow joint spaces and osteoporosis (4).
Collection of Parameters: Deformity characteristics and measured DPs were not the same for different reference
epiphyses. Although different reference
epiphyses were chosen, the final results of deformity correction were identical.8 Uniform and characteristic reference
epiphyses helped simplifies and understand permanent anatomical landmarks such as the patella and ankle joint.
The age at each stage of an epiphyseal union is a parameter known to be multifactorial [3, 4, 7,12-17], which will consequently affect the process of the union at the
epiphyses. The differences in geographical distribution, socioeconomic status, climate, metabolism, nutrition, and genetics (race) comprise some of these factors.
Her bone age at her calendar age of 6 years was 2 years (as assessed by the Greulich and Pyle method), and cone-shaped
epiphyses and Madelung deformity were noted (Figures 1(b) and 1(c)).
Among them, Goldberg and Watson [9] reported that, following nonvascularized toe to finger transfer that included the epiphyseal plate for congenital finger deficit that 91%, 67%, and 50% of
epiphyses were open among patients of 0.5-1.5, 1.5-5, and at least 5 years of age, respectively, at the time of operation, which was based on a mean follow-up of 3.4 years.
The plain radiograph of his wrists showed cone-shaped
epiphyses of the middle phalanges of the second digit of both hands with moderate deviation of the phalangeal axis (Figures 4(a) and 4(b)).
Men usually present with continuing linear growth after puberty, tall stature, unfused
epiphyses, delayed bone age, genu valgum, decreased bone mineral density, obesity, dyslipidemia, liver steatosis, insulin resistance, and impaired fertility.
