Dror Paley, M.D., FRCSC, is the director of the Paley Advanced Limb Lengthening Institute at
St. Mary’s Hospital in West Palm Beach, Florida. Dr. Paley was the founder and director of the Rubin
Institute for Advanced Orthopedics and the co-director of the International Center for Limb Lengthening until
May 2009. Prior to that he was the Chief of Pediatric Orthopedics at the University of Maryland in Baltimore
1987-2001. He is internationally recognized for his expertise in limb lengthening and reconstruction. Dr
Paley trained under the guidance of Professor Ilizarov of Russia (Ilizarov method) and Professor Debastiani of
Italy (Orthofix method). In 1986, he introduced the Ilizarov method to the US and Canada. Since that time,
he has performed more than 17,000 limb lengthening and reconstruction-related procedures on patients
from all over the United States and from more than 70 countries from six continents.
Delivering Innovative Solutions
Dr. Paley has developed more than 100 new operative procedures for bone and soft tissue reconstruction of
congenital, developmental and post-traumatic limb disorders. (e.g. superhip procedure, superknee
procedure, superankle procedure, ulnarization, percutaneous Gigli saw osteotomy, focal dome osteotomy,
angulation-translation osteotomy, etc). His new methods to lengthen and/or straighten deformed bones
and to reconstruct congenital short limbs (LRS) avoid amputation, a frequently recommended alternative.
The results of LRS for conditions such as fibular hemimelia, tibial hemimelia and congenital femoral deficiency
have given children who would have otherwise lost their legs, excellent function without the need for a
prosthesis. Furthermore the methods used to classify these conditions now bear his name.
Dr. Paley has also discovered a new, simple, but accurate method for prediction of leg length discrepancy and
height at skeletal maturity. The Multiplier method has replaced the previous more complicated methods. His
method for using a combination of an intramedullary rod and an external fixator (LON and FAN of
deformities) has shortened the treatment time required with an external fixator while maintaining the
accuracy of correction. Dr Paley is also currently the most experienced surgeon using fully implantable limb
Perhaps his most noteworthy contribution to medicine is the science of limb deformity correction. This is
published in his 800-page textbook, Principles of Deformity Correction (Springer Verlag, 2002). This book
has been reprinted 4 times and is considered an orthopedic best seller.
Treatment for Special Orthopedic Conditions
Dr. Paley’s expertise extends equally to children and adults, as well as for the upper and lower extremities. He specializes in the
diagnosis and treatment of:
Congenital lower limb deformities (eg., congenital femoral deficiency [PFFD], hemihypertrophy, fibular hemimelia, tibial hemimelia,
posteromedial tibial bow, congenital dislocation of patella, congenital pterygium of knee, congenital pseudarthrosis)
Congenital upper limb deformities (e.g., short humerus and forearm, radial clubhand, ulnar clubhand, radiohumeral synostosis,
radioulnar synostosis, syndactyly, absent thumb, polydactyly, congenital pterigium of elbow)
Other upper and lower limb deformities due to: growth arrest, fractures, radiation, infection.
Post-traumatic limb deformities and leg length discrepancies (e.g., malunion)
Bone healing problems (e.g., problem fractures, delayed union, nonunion, congenital pseudoarthrosis)
Bone defects, bone and joint infections (e.g., osteomyelitis, septic arthritis, sequellae of neonatal sepsis)
Skeletal dysplasias (e.g., achondroplasia, hypochondroplasia, spondyloepiphyseal dysplasia, pseudoachondroplasia,
chondrometaphyseal dypslasia, mesomelic dysplasia, Ellis-van Creveld, melorheostosis, diastrophic dwarfism)
Tumor-like conditions (e.g., fibrous dysplasia, neurofibromatosis, multiple hereditary exostoses (MHE), Ollier’s disease)
Metabolic disorders (e.g., rickets, Paget’s disease, osteogenesis imperfecta, osteopetrosis)
Other miscellaneous developmental deformities (e.g., Blount’s disease, growth arrest, neonatal sepsis sequelae)
Joint contractures and joint stiffness (e.g., Perthes disease, knee and ankle arthritis)
Foot deformities (e.g., clubfoot, vertical talus, dropfoot, equinus, flatfoot, short metatarsals (brachymetatarsia), Charcot-Marie-
Hip dysplasia in young adults and neonatal septic hip sequellae
Short residual limb following amputation
Joint preservation for arthritis of the hip, knee and ankle
Peripheral nerve disorders (e.g., nerve entrapment)
Constitutional short stature
Dedication to Teaching
Dr. Paley organized the first Ilizarov course in 1987 and the first ASAMI North America (Limb Lengthening and Reconstruction
Society) meeting in 1989. He served as the first president of this subspecialty society. He organizes and runs the
internationally attended Annual Baltimore Limb Deformity Course since 1989. He has lectured and demonstrated surgery in
more than 50 countries and provides training for specialists from around the world through a fellowship program.
