In animal studies, when this deletion was introduced to developing birds, their wing buds were noted to take on limb-like structures. [3] The condition was first described by Dr. F. Liebenberg in 1973 while he followed multiple generations of a South African family, [4] but it has since been noticed in other family lineages across the world. [2]
The Anterior Interosseus Nerve (AIN), a branch of the median nerve, only accounts for the movement of the fingers in hand and does not have any sensory capabilities. Therefore, the AIN syndrome is purely neuropathic. AINS is considered as an extremely rare condition because it accounts for less than 1% of neuropathies in the upper limb.
Symbrachydactyly is a congenital abnormality, characterized by limb anomalies consisting of brachydactyly, cutaneous syndactyly and global hypoplasia of the hand or foot. [1] In many cases, bones will be missing from the fingers and some fingers or toes may be missing altogether.
Compartment syndrome is a serious condition. [5] Increased pressure in a body compartment can harm blood flow and tissue function. [5] [6] [7] If not treated quickly, it may cause permanent damage. [7] There are two types, acute and chronic. [8] Acute compartment syndrome can lead to a loss of the affected limb due to tissue death. [6] [9]
Oligodactyly is sometimes a sign or symptom of several syndromes including Poland syndrome and Weyer Ulnar Ray Syndrome. [5] It is a type of dysmelia . Ectrodactyly is an extreme instance of oligodactyly, involving the absence of one or more central digits of the hand or foot and is also known as split hand/split foot malformation (SHFM). [ 6 ]
In addition to instances of asomatognosia in which patients deny ownership of a specific part, this condition is also associated with the following: anosognosia (unawareness or denial of illness), anosodiaphoria (indifference to illness), autopagnosia (inability to localize and name body parts), and asymbolia for pain (absence of typical reactions to pain).
Acheiropodia was first described in Brazil in 1929 [4] and the variations in expression (the range in severity and type of signs and symptoms experienced by patients), namely the presence or absence of digits on upper limbs or the Bohomeletz bone (a small, elongated bone located at the upper limb tips, parallel to the humerus and suggested to be what would have developed into the ulna), were ...
Stiff-person syndrome (SPS), also known as stiff-man syndrome, [1] is a rare neurological disorder of unclear cause characterized by progressive muscular rigidity and stiffness. The stiffness primarily affects the truncal muscles and is characterised by spasms , resulting in postural deformities.
