About OS Clinic
Professor Nima Heidari, MBBS MSc PhD FRCS (Tr&Orth), a consultant foot, ankle and limb reconstruction surgeon who previously led the Bone Infection and Limb Reconstruction Unit at the Royal London Hospital, co-founded OS Clinic, a multi-specialty orthopaedic practice in central London. Surgery takes place at The London Clinic on Devonshire Place, with consulting at Prime Health on Queen Anne Street. Limb lengthening is a minority of the workload, inside a bone infection and reconstruction programme that also includes consultant plastic surgeons. Methods listed are LON and LATN.
No price is published. The website describes internal and external fixation generically, so the specific implant brands Heidari uses are not confirmed; ask. The practice is CQC registered. Its Google listing shows 5.0 from 292 reviews and Doctify 4.92 from 187, ratings that cover the whole practice. An international programme coordinates hospital stays, embassy and sponsor letters of guarantee and payment.
OS Clinic's website describes internal and external fixation for limb lengthening generically without naming specific implant brands (PRECICE, Stryde, etc.) — specific devices used by Prof. Heidari not confirmed from public sources. Limb lengthening appears to be a minority speciality alongside the dominant foot/ankle and bone infection workload. Second limb reconstruction consultant (Mr Thomas Hester) also listed at the clinic but primary limb lengthening lead is Prof. Heidari.

What does recovery look like after surgery at OS Clinic?
