Clinically this study lends insight to the strength of bone-retinaculum-bone autografts and the etiology of extensor carpi ulnaris subluxation. This study offers detailed analysis of the extensor retinaculum compartments and 3-dimensional anatomy of the septal attachments. Compartment 6, which was thought to be the weakest because of clinically observed subluxation of the extensor carpi ulnaris tendon, had stronger failure data than expected. Abbreviations: ALS, APL-Lister-scaphoid APL, abductor pollicis longus EPL, extensor. These extensor tendons are held in place inside their compartment by the extensor retinaculum, a strong transverse ligament that the tendons pass under. Anatomic landmarks used for location of first dorsal compartment of wrist. Compartment 3: Extensor pollicus longus, extensor carpi radialis longus. There are in fact 6 separate compartments on the back (dorsum) of the wrist that contain tendons of muscles that extend (as opposed to flex) the wrist and the fingers and thumb. In compartment testing, compartments 1 and 2 had the highest overall resistance to failure and compartment 5 had the lowest. Drummer's wrist, traumatic rupture with distal radius fx : 4.
Septum 1/2 also was found to have the highest failure strength at 51.3 +/- 15.3 N. This study aims to evaluate a series of patients without RA, having extensor tendon tenosynovitis, its pathology, and results of surgical treatment. The Extensor Compartments of the Wrist wrist extensors Extrinsic extensor muscles of the hand Wrist Extensors Anatomy wrist extensors wrist. Septum 1/2 had the largest radial surface area and septum 3/4 had the smallest. The musculotendinous junctions of the first extensor compartment tendons (abductor pollicis longus and extensor pollicis brevis tendons) intersect the second. Purpose Proliferative tenosynovitis of the extensor tendons is a very common painful wrist condition that can occur both in presence and absence of rheumatoid arthritis (RA). This evaluation tool outlines the location of different extensor tendon compartments in the hand and common pathologies seen in each compartment. It can be difficult to determine the best course of action when evaluating the dorsal wrist tendons. Finally the 6 extensor retinaculum compartments were tested to failure. Wrist extensor tendinopathies are a less often encountered diagnosis in rehabilitation settings. The top 4 are: wrist, tendon, radius and ulna.You can get the definition(s) of a word in the list below by tapping the question-mark icon next to it. Next each extensor retinaculum septum was excised as a bone-retinaculum-bone autograft and was tested in tension to failure with a materials testing machine. Below is a list of extensor tendon compartments of the wrist words - that is, words related to extensor tendon compartments of the wrist. First, anatomic measurements of the individual extensor retinaculum septums were performed with calipers and a 3-dimensional digitizer. Thirty-four wrists from 24 fresh-frozen and 10 embalmed cadavers were used. Platysma Muscle - Origin, Insertion, Exercise | Samarpan Physio.The anatomy of the extensor retinaculum of the wrist has been described previously the purpose of this study was to describe the specific anatomy of the septal attachments on the radius and to investigate the mechanical strength of each septal attachment on the radius and each of the 6 compartments of the extensor retinaculum.
The wrist extensors includes extensor carpi radialis longus (ECRL), extensor carpi radialis brevis (ECRB), extensor digitorum (ED), extensor digiti minimi (EDM), extensor carpi ulnaris (ECU) and extensor indicis (EI). These compartments contain tendons of muscles that pass from forearm to hand. The wrist extensor muscles of the hand are located in the back of the forearm and have long tendons connecting them to bones in the hand, where they exert their action. The Extensor Zone VII (wrist) contains 6 extensor compartments comprising of 6 synovial sheath lined tunnels separated from each other by fibrous sheath. The condition is thought to occur as a result of repetitive friction at the junction in which the tendons of the first dorsal compartment cross over the second, creating tenosynovitis. Resistance Band Wrist Extensor Exercise : Intersection syndrome is a condition that affects the first and second compartments of the dorsal wrist extensors.
