Skeletal Maturity Indicators Important Notes

Skeletal Maturity Indicators

  • Skeletal maturity indicators
    • Hand wrist radiographs
    • Skeletal maturation using cervical vertebrae
    • Clinical and radiographic examination of stages of tooth development
  • Fishman’s skeletal maturity indicator
    • It evaluates hand-wrist radiographs making use of anatomical sites located on the thumb, third finger, fifth finger, and radius
    • 11 skeletal maturity indicators were described covering the entire period of adolescent development
    • Interpretation uses four stages of bone maturation
      • Epiphysis equal in width to diaphysis
      • Appearance of abductor sesamoid of the thumb
      • Capping of epiphysis
      • Fusion of epiphysis

Skeletal Maturity Indicators Short Essays

Question 1. Hand Wrist Radiograph.

It is one of the skeletal maturity indicators

Significance Of Hand Wrist Radiograph:

  • Describes ossification and union of small bones of hand and wrist
  • Determines skeletal age of patients

Indications Of Hand Wrist Radiograph:

  • In the discrepancy between dental and chronological age
  • Determines the skeletal age of the patient
  • Determines skeletal malocclusion
  • Predict future skeletal growth
  • Predict pubertal growth spurt
  • Aid in research
  • Assess the growth status of individual

Methods Of Hand Wrist Radiograph:

  • Atlas method by Greulich and Pyle
  • Bjork, Grave, and Brown’s method
  • Fishman’s skeletal maturity indicator
  • Hagg and Taranger’s method

Anatomy Of Hand Wrist:

Consist of:

  • Distal ends of long bones of the forearm
  • Carpals
  • Metacarpals
  • Phalanges

Question 2. Maturity Indicators.

Importance Of Maturity Indicators:

  • Determine the stage of maturity
  • Assess skeletal growth
  • Decides the treatment planning
  • Helps in objective diagnosis
  • Assess different ossification centers

Methods Of Maturity Indicators:

  • Hand wrist Radiograph
  • Cervical vertebrae
    • By Hassel and Farman
    • Shapes of cervical vertebrae determine stages of development
    • Shapes of C3 and C4 are compared

    • Inferior vertebral borders were examined
      • Flat – when immature
      • Concave – when matured
    • Six stages in vertebral development are viewed
  • Tooth Mineralization
    • Selected teeth – lower canine
    • Calcification patterns and stages of mineralization are examined
  • Maxillary sinus
  • Frontal sinus

Question 3. Carpal index.

  • One of the skeletal maturity indicator
  • Used as a part of hand wrist
  • Carpals – consist of eight small bones arranged in
    • Proximal Row
      • Scaphoid
      • Lunate
      • Triquetral
      • Pisiform
    • Distal row
      • Trapezium
      • Trapezoid
      • Capitate
      • Hamate
        • These bones show specific patterns of appearance, ossification, and union
        • These are compared with standards

Skeletal Maturity Indicators Viva Voce

  • Skeletal age is useful throughout the post-natal growth period
  • Dental age as a maturity indicator is useful from birth to early adolescence
  • Morphological age as a maturity indicator is useful from late infancy to early adulthood
  • 29 bones are included in the hand-wrist region
  • The radius and ulna are long bones of the hawristist region there are 8 carpal bones in the hand wrist
  • There are 5 metacarpal bones in the hand wrist
  • Each digit of the hand has proximal middle and distal phalanges
  • Sesamoid is small nodular bone
  • There are 1 primary ossification center and one secondary ossification center for each metacarpal bone
