Central Polydactyly of Fingers

Mirror Hand


Presentation

  • The anomalies are organized by anatomical system and presented in a consistent manner, including details of the clinical presentation, epidemiology, embryology, treatment and prevention for each anomaly.[books.google.com]
  • There is no tendon present in the extra digit and neurovascular bundle may be present or absent. Presence of two extra digits is very rare; Polydactyly is most common in an African population. 2.[wikiexclusive.com]
Pathologist
  • All clinicians and scientists interested in birth defects, including pediatricians, geneticists, genetic counselors, obstetricians, and pediatric pathologists, will find this book to be an invaluable source of information.[books.google.com]
Pediatric Disorder
  • Pediatric Hand and Upper Limb Surgery guides you to the present indications for intervention and care in upper limb pediatric disorders.[books.google.com]
Distractibility
  • Provides up-to-date details on rib-based distraction implants (VEPTR ) and remote-controlled growing rods (MAGEC) for scoliosis; diagnosis of femoroacetabular impingement (FAI) and its influence on development of osteoarthritis; and the treatment of FAI[books.google.com]

Workup

  • […] technique a segmental distal transfer (on-top plasty) Postaxial Polydactyly (Small Finger Duplication) Epidemiology demographics Genetics inherited as autosomal dominant (AD) in African Americans more complex genetics in caucasians and a thorough genetic workup[orthobullets.com]
  • Since it is a condition that is generally uncommon in Caucasians, genetic workup should be considered in a Caucasian child with polydactyly. Preaxial Polydactyly : Preaxial polydactyly means that the extra digit(s) is on the thumb or big toe side.[adoption.umn.edu]
  • Propanolol therapy should be preceded by a full cardiovascular workup, and be managed carefully by a pediatrician and plastic surgeon due to an increased risk of hypoglycemia, hyperkalemia, and bradycardic hypotension.[surgery.wisc.edu]

Treatment

  • Complete with plentiful photographs and illustrations to guide the clinician in preparing for and performing the necessary treatments, this is an essential book for hand surgeons, orthopedists and plastic surgeons.[books.google.com]

Prognosis

  • […] non-syndromic macrodystrophia lipomatosa syndactyly : most common associated limb anomaly, it is then termed polysyndactyly If it is an isolated anomaly it is incidental and not of concern but if associated with another anomaly it then carries a vastly variable prognosis[radiopaedia.org]

Etiology

  • Each chapter has a case presentation, series of clinical questions, and fundamentals on etiology and epidemiology, clinical evaluation, and surgical indications.[books.google.com]
  • Etiology The cause is unknown, unless the condition is associated with a syndrome.[orthopaedicclinic.com.sg]
  • […] concerning dermatopathology and pathology Atlas of fetal pathology Congenital malformations Physiological developement of an embryo and fetus, growth and changes of the external shape Congenital malformations and congenital anomalies Basic terminology Etiology[atlases.muni.cz]
  • Etiology Ulnar-sided polydactyly exhibits strong autosomal dominant inheritance with variable expressivity, often bilateral, and is almost never associated with systemic or syndromic conditions.[dermatologyadvisor.com]

Pathophysiology

  • Pathophysiology Genetic and environmental factors interact during the fourth through seventh weeks of gestation to produce polydactyly.[dermatologyadvisor.com]

Prevention

  • During the course of this surgery, ligaments may need to be moved into different positions in order to prevent the forefoot from becoming deformed or widened. After surgery a cast or orthosis may be used for this purpose.[drbishnubd.com]
