What Children's Orthopaedic and Scoliosis Surgery Associates does

Children's Orthopaedic and Scoliosis Surgery Associates, LLP (COSSA) is a private, physician-owned pediatric orthopaedic medical practice founded in 1988 and headquartered in St. Petersburg, Florida. The practice is structured as a Florida Limited Liability Partnership and provides specialized musculoskeletal care exclusively to children and young adults across Florida's SunCoast Region, with offices in St. Petersburg, Tampa, and Lakewood Ranch. Six fellowship-trained, board-certified pediatric orthopaedic surgeons deliver diagnosis, non-surgical management, and surgical treatment for scoliosis, kyphosis, sports injuries, fractures and trauma, congenital deformities of the hands and feet, hip preservation conditions, hand and upper extremity disorders, foot and ankle conditions, and neuromuscular disorders including cerebral palsy.

The practice's clinical technology stack centers on a CAT scan-based intra-operative navigation system used in all spine surgeries for accurate pedicle screw placement, complemented by digital radiography, a cutting-edge arthroscopy suite for minimally invasive sports medicine procedures, and an OR equipped with advanced imaging and specialized pediatric instrumentation. The practice conducts more than 120 scoliosis surgeries per year and has collective scoliosis surgery experience exceeding 30 years. Patient-facing technology includes a secure online portal, Phreesia-powered appointment scheduling, an educational video and animation library, and downloadable brochures covering 40+ conditions.

COSSA operates a fee-for-service revenue model through insurance billing, accepting major commercial plans (Aetna, Blue Cross Blue Shield, Cigna, United Healthcare, and others) with patient responsibility collected at time of service, plus ancillary revenue from waterproof casting materials. The go-to-market motion is sales-led via physician referrals from primary care physicians and pediatricians, supplemented by direct online and phone-based patient scheduling. The practice maintains academic affiliations with the University of South Florida College of Medicine (primary clinical rotation site) and a clinical partnership with Johns Hopkins All Children's Hospital, which is ranked #25 nationally for pediatric orthopedics by U.S. News & World Report in 2025.

Broad incumbents

• Texas Scottish Rite for Children: Pediatric orthopaedic specialty hospital in Dallas specializing in scoliosis, sports medicine, and complex pediatric orthopaedic care. Highly comparable specialty focus to COSSA, particularly the scoliosis surgery franchise, though structured as a specialty hospital rather than a private practice.
• Cincinnati Children's Hospital: Top-ranked pediatric academic medical center with a high-volume pediatric orthopaedic service line including scoliosis, sports medicine, and CP treatment. Comparable clinical scope at integrated hospital-system scale.
• Nemours Children's Health: Multistate pediatric health system with strong Florida presence (Jacksonville, Orlando) offering pediatric orthopaedic services, scoliosis care, sports medicine, and CP treatment — directly comparable patient mix and conditions treated to COSSA, though operating at integrated health-system scale.
• Boston Children's Hospital: Premier pediatric academic medical center with nationally ranked pediatric orthopaedics, scoliosis surgery, and sports medicine programs. Comparable clinical scope to COSSA's full-service pediatric orthopaedic offering, though at academic-medical-center scale.
• Children's Hospital of Philadelphia (CHOP): Top-ranked U.S. pediatric hospital with one of the largest pediatric orthopaedic programs in the country. Source of COSSA surgeon training (Dr. Piazza) and a benchmark for the practice's clinical aspirations across scoliosis, sports medicine, and CP.
• Hospital for Special Surgery (HSS): National leader in orthopaedics with a dedicated pediatric program covering scoliosis, sports medicine, and complex reconstruction. Comparable surgical expertise and orthopaedic specialization, though HSS is adult-focused with pediatric as a sub-line versus COSSA's purely pediatric focus.
• Children's National Hospital: Pediatric academic medical center in Washington, D.C. with a robust orthopaedic surgery and sports medicine program. Comparable pediatric orthopaedic service mix (scoliosis, sports medicine, fracture care, neuromuscular), though operating at academic-medical-center scale.
• Children's Healthcare of Atlanta: Large pediatric health system with a high-volume pediatric orthopaedic and scoliosis program. Comparable service line breadth (scoliosis, sports medicine, CP, fracture care) but operates at integrated hospital-system scale versus COSSA's private practice model.
• Shriners Children's: National pediatric specialty hospital network with a deep pediatric orthopaedics franchise (scoliosis, sports medicine, CP, hand/upper extremity). Closest national-level analog to COSSA's pediatric orthopaedic specialty mix, though operates as a multi-site hospital system.

Regional players

• Rady Children's Hospital-San Diego: Pediatric specialty hospital with a notable pediatric orthopaedic program and recognized cerebral palsy expertise (where COSSA's Dr. Bland trained). Highly comparable CP and pediatric orthopaedic service mix, but serves the Southern California market rather than Florida.
