Paediatric, reconstructive. Neither the programme page nor the PRECICE news story names a surgeon — the roster was assembled from individual CHOP profiles, the Penn faculty directory and the LLRS roster. The flagship technology article dates from June 2016; no newer CHOP limb lengthening content was found. Given Dr Davidson's tenure, confirm he is still operating rather than clinic-only. Added 2026-08-12 in the US roster expansion; provenance in docs/research/us-expansion-2026-08/.
Why we listed this clinic
Dr Davidson is a past president of the Limb Lengthening and Reconstruction Society and has been at CHOP since 1982. Dr Horn and Dr Goodbody are also LLRS members. The programme uses electromagnetic lengthening rods and plates, growth modulation and vascularized bone grafts, and describes external fixation as a legacy approach it now tries to avoid.

Verification covers: named surgeon credentials, hospital affiliation, methods offered, public-facing website, and regulatory status. We re-verify quarterly. If a clinic fails a re-verification, we add an editorial note or demote its tier — we do not quietly remove it.
Independence: this clinic cannot pay to change its ranking, Directory Score, tier, or reviews. Paid options affect presentation only and are always labeled. We take no commission and charge no per-patient fee. Editorial policy.
This directory is editorial. It is not medical advice, an endorsement, or a substitute for consultation with a qualified surgeon. Pricing and availability change — always verify directly with the clinic before making decisions.
