Management for the long limb.Is there a role for amputation?Amy L. McIntosh MDPediatric Orthopedic Surgeon CP1013403-1
Limb Hypertrophy • Soft tissue and or bone enlargement • Extremities • Lower (nearly all) • Upper • Pelvis and Thorax
Evaluation • History • Examination • Imaging • Radiographs • Bone age • Scanogram CP1013403-2
Phyiscal Examination • Assess LLD w/ pt. standing • Add blocks (known height) until the pelvis is level
Radiographs (Bone Age) • A film of the left hand • Compared to a book of radiographs of children’s hands of known ages • Gives an estimate of bone maturity growth remaining

Yes!!! Significant length discrepancy Poor underlying bone quality for lengthening Dysfunctional/ painful limb Is there a role for amputation??
