Extensor retinaculum, a fascia that holds the tendons of the carpal extensor muscles was observed in the distal row of the carpal bones
GCT of carpal bones
affected in 31% the hamate, in 24% the capitate, in 14% the scaphoid, in 10% the lunate, in 7% the triquetrum, in 7% the trapezium, in 7% the trapezoid, and multifocal appearance was found in 14% of all cases .
The mobilization involves pushing and moving the row of carpal bones
either dorsally to increase wrist extension or to the palmar side to increase wrist flexion.
Indeed Afifi and Lu (2011) have previously commented that the overlapping of the carpal bones
makes plain radiographs difficult to interpret and this has been supported by previous authors (Sadowski and Montilla, 2008).
14,15) Due to the limited blood supply of the lunate, especially the proximal pole, it is the main carpal bone
vulnerable to post-traumatic avascular necrosis.
Greater arc injuries" are defined as carpal bone
or radial styloid fractures prior to lunate dislocation due to slower applied load (3).
After the carpal bones
are exposed, cartilage damage is assessed, and soft tissue is debrided.
The back wall of the carpal tunnel is bound by the carpal bones
and a band of strong tissue called transverse carpal ligament.
This syndrome is characterized by upper extremity malformations involving radial or carpal bones
, and a personal and family history of congenital heart malformation, most commonly ostium secundum atrial septal defect.
Magnetic resonance imaging of the right hand showed numerous sclerotic lesions in the distal radius, ulna, carpal bones
and metacarpal head.
These articulate with each other at the proximal and distal radio-ulnar joints and also with the carpal bones
consisting of eight small bones.
The carpal tunnel is a space located posteriorly between the carpal bones
of the wrist (moving from fight to left: trapezium, trapezoid, capitate, and hamate), forming the hard "carpal floor," and anteriorly, where the transverse carpal ligament forms a fibrous sheath or the "carpal roof" (see Fig 1).
