Radial dysplasia, also known as radial club hand or radial longitudinal deficiency, is a congenital difference occurring in a longitudinal direction resulting in radial deviation of the wrist and shortening of the forearm.
Madelung's Deformity is usually treated by treating the distal radial deformity. However, if patients have a positive ulnar variance and focal wrist pathology, it’s possible to treat with an isolated ulnar-shortening osteotomy. In these patients the radial deformity is not treated. [5] The ulna is approached from the subcutaneous border.
Thumb hypoplasia is a spectrum of congenital abnormalities of the thumb varying from small defects to complete absence of the thumb. [1] It can be isolated, when only the thumb is affected, and in 60% of the cases [2] it is associated with radial dysplasia [1] (or radial club, radius dysplasia, longitudinal radial deficiency).
Ulnar dysplasia also known as ulnar longitudinal deficiency, ulnar club hand or ulnar aplasia/hypoplasia is a rare congenital malformation which consists of an underdeveloped or missing ulnae bone, causing an ulnar deviation of the entire wrist. The muscles and nerves in the hand may be missing or unbalanced.
Holt–Oram syndrome (also called atrio-digital syndrome, atriodigital dysplasia, cardiac-limb syndrome, heart-hand syndrome type 1, HOS, ventriculo-radial syndrome) is an autosomal dominant disorder that affects bones in the arms and hands (the upper limbs) and often causes heart problems. [1]
Radial aplasia is a congenital defect which affects the formation of the radius bone in the arm. The radius is the lateral bone (thumb side) which connects the humerus of the upper arm to the wrist via articulation with the carpal bones. A child born with this condition has either a short or absent radius bone in one or both of his or her arms.
Brachydactyly-elbow wrist dysplasia syndrome [1] Liebenberg syndrome is a rare autosomal genetic disease that involves a deletion mutation upstream of the PITX1 gene , which is one that's responsible for the body's organization, specifically in forming lower limbs. [ 2 ]
Often, every joint in a patient with arthrogryposis is affected; in 84% all limbs are involved, in 11% only the legs, and in 4% only the arms are involved. [4] Every joint in the body, when affected, displays typical signs and symptoms: for example, the shoulder (internal rotation); wrist (volar and ulnar); hand (fingers in fixed flexion and thumb in palm); hip (flexed, abducted and externally ...
