The extensor retinaculum of the wrist. The dorsal retinaculum of the wrist consists of two layers: the supratendinous and the infratendinous. The infratendinous layer is limited to an area deep to the ulnar three compartments. There are six compartments for the tendons dorsal to the wrist separated by six longitudinal vertical septa The additional dissection and suturing extend the duration of surgery, and not all surgeons routinely include inferior extensor retinaculum augmentation in anterior talofibular ligament repairs. To determine whether there is a reasonable basis for this surgery, we ascertained the degree to which inferior extensor retinaculum augmentation. Through an anatomical and biochemical study, utilizing sixty-five cadaver specimens, the extensor retinaculum of the wrist was examined. It is a complex variable fibrous structure, whose functions are to prevent dorsal bowstringing of the extensor tendons and to prevent radial and ulnar displacement of extensor tendons The extensor retinaculum in the foot is a thick band that runs from the front of the ankle joint to the back of the foot.

The Extensor Tendons are located on the back of the hand, just below the skin, and directly above the hand bones. This makes them prone to injury due to the lack of muscle or other protective tissues. Anything from minor cuts to major hand trauma can result in injury to these tendons. Crushing injuries, such as jamming fingers in a door frame. It is part of the extensor mechanism of the knee, 27385 for primary repair or 27386 for secondary reconstruction. The extensor mechanism includes the quadriceps mucle group, quadriceps tendon, patella, patellar retinaculum, patellar ligament or adjacent soft tissues Extensor retinaculum From the deep surface of the extensor retinaculum fibrous septa pass to the bones of the forearm, dividing the extensor tunnel into six compartments. 10. Extensor retinaculum 1. The most lateral compartment lies over the lateral surface of the radius at its distal extremity, and through it pass the tendons of abductor.

What is the Extensor Retinaculum? (with pictures

Extensor digitorum is a superficial muscle of the posterior compartment of the forearm. Like the majority of the muscles in this compartment, it originates via common extensor tendon that arises from the lateral epicondyle of humerus. This tendon serves as a proximal attachment for extensor digiti minimi, extensor carpi radialis brevis and extensor carpi ulnaris muscles The extensor tendon compartments of the wrist are six tunnels which transmit the long extensor tendons from the forearm into the hand. They are located on the posterior aspect of the wrist. Each tunnel is lined internally by a synovial sheath and separated from one another by fibrous septa.. In this article, we shall look at the anatomy of the extensor compartments of the wrist - their. The extensor retinaculum at the dorsal aspect of the wrist establishes a mechanism that strongly restricts the extensor tendons. This retinaculum is derived from the deep parts of the antebrachial fascia and consists of two layers: supratendinous and infratendinous (, Fig 5) Foot extensor tendons run from the tips of your toes to the front of your legs. If you're experiencing pain when your feet move, you may have tendonitis — which means your tendons are injured or inflamed. Foot extensor tendonitis exercises are an important part of the rehabilitation process The inferior extensor retinaculum (IER) is a retaining aponeu-rotic structure located on the anterior aspect of the ankle and tarsus that is continuous with the sural fascia.

The inferior extensor retinaculum is an X- or Y-shaped structure subdivided into roots and oblique superomedial, oblique inferomedial, and variable oblique superolateral limbs below the ankle joint. The stem, particularly the medial root, of the inferior retinaculum forms a constraining loop around the EDL and peroneus tertius tendons.. The ECU, its subsheath, and the extensor retinaculum are readily seen using MRI (7a). 5 . Figure 5: An overview of the ECU at the level of the distal ulna with a cutaway of the extensor retinaculum reveals the band-like subsheath (red) which serves to stabilize the ECU tendon within its groove at the distal ulna. 6 The extensor retinaculum is imbricated in an oblique fashion from distal-ulnar to proximal-radial. Indications, essential steps, postoperative care, and sample operative dictation are included.

Inferior Extensor Retinaculum PainCausesSymptoms Treatmen

The dorsal extensor retinaculum of the wrist is composed of two primary layers . The supratendinous retinaculum originates 2 to 3 cm proximal to the radiocarpal joint and ends distinctly at the carpometacarpal joints. The most radial attachment on the distal radius forms the radial septum for the first extensor compartment The aim of our study was the assessment of the mid-term outcome of patients treated with a pediculated extensor retinaculum flap for extensor carpi ulnaris (ECU) tendon subluxation including postoperative tendon stability control. Twelve patients treated with an extensor retinaculum flap for symptomatic ECU tendon instability were retrospectively evaluated Furthermore, each suture knot between the autograft and stump was created far from the proximal end of the superior extensor retinaculum and the distal end of the superior part of the inferior extensor retinaculum, ensuring smooth sliding of reconstructed tibialis anterior tendon without impingement between the knots and the retinaculum. ZONE VII INJURY There is almost always an associated injury to the extensor Retinaculum Point in favor of excision of Retinaculum are that it improves exposure & prevents friction between bulky repairs and the retinaculum while its preservation prevents bow stringing or subluxation of the extensor tendons Treatment is same as zone VI in acute. Extensor tendon injuries of the fingers, hand, and wrist are frequently seen in the emergency department. One recent study found 33.2 tendon injuries to the hand/wrist per 100,000 person-years. 1 These injuries occur more often in males than females and have their highest incidence between 20 and 29 years of age. 1,2

The Herbert sling, which is an extensor retinaculum capsulorrhaphy, is an effective method of creating a strong tether among the distal radius, ulna, and ulnar carpus. Preliminary biomechanical and clinical results have been encouraging Now, he has R/F pins and needles pain above and below medial malleolus, which comes out randomly during the day, i.e. sleep, activities, at rest; shooting pain at extensor digitorum brevis muscle which radiate to the 4th metatarsal; burning pain from medial base of 1st MTPJ radiating to the calf (on and off - particularly after long.

Here's the anterior tibial artery at the ankle, passing beneath the extensor retinaculum. We'll remove the retinaculum. As it passes in front of the ankle, the anterior tibial artery crosses beneath extensor hallucis longus, emerging lateral to it. It gives off branches to the tarsal region, then continues on to the dorsum of the foot the extensor retinaculum/ synovial pouches at the wrist level. Dynamic traction for the digits with the wrist immobilized, or controlled motion during formal therapy sessions are often insufficient to prevent inter-tendinous adhesion. 3. Functional limitations with injury proximal to zone VIII may limit composit The inferior fibular retinaculum is continuous in front with the inferior extensor retinaculum, and is attached posteriorly to the lateral surface of the calcaneus. Some of its fibres are fused with the periosteum on the fibular trochlea (peroneal tubercle) of the calcaneus, forming a septum between the tendons of fibularis longus and brevi Boutonniere can happen from a cut or tear of the extensor tendon (Figure 3). Cuts on the back of the hand can injure the extensor tendons. This can make it difficult to straighten your fingers. Figure 1.
