What this specialty covers
An orthopaedic surgeon is trained in the preservation, investigation and restoration of the form and function of the extremities, spine and associated structures by medical, surgical and physical means. An orthopaedic surgeon is involved with the care of patients whose musculoskeletal problems include congenital deformities, trauma, infections, tumors, metabolic disturbances of the musculoskeletal system, deformities, injuries and degenerative diseases of the spine, hands, feet, knee, hip, shoulder and elbow in children and adults. An orthopaedic surgeon is also concerned with primary and secondary muscular problems and the effects of central or peripheral nervous system lesions of the musculoskeletal system.
Reading the sole-proprietor share
For this specialty, 4,535 records, or 12.7%, are flagged as sole proprietors in NPPES. This self-reported field is an imperfect proxy for private practice because it reflects reported organizational status, not necessarily how an orthopaedic surgeon practices, bills, or is affiliated with a group or health system.

Data notes
- The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
- A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
- - The total counts active NPI records with this as the primary taxonomy, so it is not a census of every physician providing orthopaedic care.
- - State totals reflect NPPES record geography and do not show where patients are treated or how practices are organized.
- Providers are counted once, by their primary taxonomy code only.
