At the carpal tunnel entrance and proximal carpal tunnel, thickness of retinaculum (RT) were measured.
The deep fascia of the foot is thin on the dorsum of the foot where it is continuous with the inferior extensor retinaculum. Over the lateral and posterior aspects of the foot, the deep fascia is continuous with the plantar fascia (deep fascia of the sole).
(14) reported a FCUM that possessed only a humeral head; another muscle belly originating from medial epicondyle lying between flexor digitorum superficialis and FCUM and was attached to triquetral, hamate bones, and flexor retinaculum.
The median nerve extends just below the flexor retinaculum and between the muscles of the flexor pollicis longus and superficial digital flexor muscles.
Furthermore, there are soft tissue contractures like quadriceps, retinaculum, internal ligaments of the knee joint, associated knee joint stiffness, and extensor lag in these patients.
Extensor retinaculum, a fascia that holds the tendons of the carpal extensor muscles was observed in the distal row of the carpal bones.
IASTM was performed over the right medial and lateral patellar retinaculum, as well as the right quadriceps and patellar tendons for approximately five minutes in total at a superficial depth.
There is usually a compression of part of a nerve with consequent disturbance of microcirculation earlier in the course of CTS, but this is restored immediately after transection of the flexor retinaculum. With this restoration of microcirculation, there is often an immediate and delayed return of nerve function which further buttresses the fact that ischemia plays a role in the development of the constellation of symptoms and signs seen in entrapment neuropathies.
The plantar ligament, retinaculum of the flexor tendons, and articular cartilage are best seen in the arthrograms, and joint space can be measured (Figs 10 and 11).
(29) In addition, the extensor retinaculum in patients with de Quervain's disease demonstrates increased vascularity and deposition of dense fibrous tissue resulting in thickening of the tendon up to 5 times its normal width.
