Why study maturity
indicators?
Key to successful treatment in
growing
patients – harnessing of growth.

 Without exact status of growth –
magnitude and direction-
treatment
planning is futile.
Advantages of Maturity
Indicators
Potential vector of facial development
determined.
Amount of significant craniofacial
growth
potential left.
To decide the onset of treatment
timing.



To evaluate treatment
prognosis
To understand role of genetics and
environment on skeletal
maturation
pattern.

Age
Expressed as:
 Chronologic age
Age measured by years
lived since birth
Dental age

Determined according
to
teeth erupted, amount of root
resorption
and amount of root formation.
Skeletal age

Determined by ossification
of various skeletal structures at
different
time.

Skeletal Age Assessment
 Regions used for skeletal age assessment
should be ideally:
 Small to restrict radiation
exposure
 Should have many ossification
centres
that ossify at different times and
which
can be standardized
 Easily accessible

Risser sign
Risser sign is a radiological tool used to assess scoliosis. It is based on
the degree of ossification and fusion of the iliac crest apophysis. This
information helps predict the risk of scoliosis progression during a
patient’s growth phase.
Grading of the Risser Sign
 Grade 0: No ossification of the iliac apophysis. Indicates early
skeletal growth and maximum potential for scoliosis progression.
 Grade 1: Ossification of the apophysis begins, covering up to 25% of
the iliac crest.
 Grade 2: Ossification progresses to cover 26–50% of the iliac crest.
 Grade 3: Ossification extends over 51–75% of the iliac crest.
 Grade 4: Ossification is nearly complete, covering 76–100% of the
iliac crest, but the apophysis is not yet fused to the iliac crest.
 Grade 5: Complete fusion of the apophysis to the iliac crest,
signaling skeletal maturity
Risser sign
Risser sign
Clinical Importance:
The Risser sign is a key component in scoliosis
management, as it helps predict growth potential and the
risk of curve progression.
 Low Risser grades (0–2): Indicate active growth phases
with a higher risk of scoliosis progression.
 High Risser grades (3–5): Suggest reduced growth
potential and a lower risk of scoliosis worsening.
Limitations:
 Differences in Risser grading systems exist between the
U.S. and Europe, with slight variations in interpretation.
 Other methods like the Tanner staging and hand-wrist
radiographs may also be used for growth assessment in
conjunction with the Risser sign.
