Medial collateral ligament The fibers of the posterior part of the ligament are short and incline backward as they descend; they are inserted into the tibia above the groove for the semimembranosus muscle. The anterior part of the ligament is a flattened band, about 10 centimeters long, which inclines forward as it descends.

Flexor retinaculum of the foot However, your feedback is important to us. Each wrist and ankle of the human body contains a structure called the flexor retinaculum. A flexor retinaculum consists of a fibrous band of fascia, which is a sheet of dense connective tissue that covers or binds other body structures.

- You may want to look into the MPFL recon versus Medial Plication. The MPFL recon has a better success rate for treating patellar instability. Medial Plication just tightens the structures. In many cases the Medial Retinaculm is too far stretched or completely torn.

Optical Coherence Tomography Scans Choroidal Neovascular Membranes/Subretinal neovascular membranes. Choroidal neovascular membranes (CNVM) can be described based on its location relative to the fovea, location relative to the retinal pigment epithelium, and fluorescein angiography findings.Location relative to the fovea: Subfoveal (underneath the fovea).hen the CNVM leaks it will start in the subretinal space and may leak into the intraretinal layers. Other types of occult CNVM includes retinal angiomatous proliferation (RAP) and polypoidal choroidal vasculopathy (PCV). Retinal angiomatous proliferation (RAP). RAP is described as type 3 CNVM. RAP involves 3 stages.

- The stromal fibrils are further organised into bundles, or lamellae, of which there are approximately 300 in the central cornea and 500 close to the limbus.9 The posterior lamellae course directly across the full width of the cornea without a break, having their origins in fibres which wind around the limbus at the corneoscleral junction10-12 or, according to Radner,9 have a pseudocircular organisation at the limbus, forming the ligamentum circulare corneae.

- The intramuscular pressure. beneath the superior extensor retinaculum of the. ankle was greater than 40 mmHg in all cases (40 to. 130 mmHg), and less than 20 mmHg in the anterior. compartment. Treatment consisted of release of the. superior extensor retinaculum and stabilisation of the. fracture. All patients had prompt relief of pain and. improved strength and sensation within 24 hours, although two had some residual numbness in the web. space of the great toe.

Retinal detachment Rhegmatogenous retinal detachment – A rhegmatogenous retinal detachment occurs due to a break in the retina (called a retinal tear) that allows fluid to pass from the vitreous space into the subretinal space between the sensory retina and the retinal pigment epithelium.

- There is surrounding edema and fluid seen around the torn medial patellar retinaculum. There is note made of some thickening of the inferior aspect of the medial collateral ligaments, although the fibers do remain intact. The findings are suggestive of partial MCL sprain. The medial and lateral meniscus remain intact.

Mottling, Spicules In the Left Fundus The right eye was completely normal. In the left eye, there was some mild mottling of the retinal pigment epithelium (RPE) in the macula. There was no subretinal fluid, but a foveal light reflex was present. Also, there were bone spicules in the inferior retina of the left eye. Our patients left eye shows bone spicules in the inferior retina.

Ligamenta flava Ligamenta flava. (Redirected from Ligamentum flavum) The ligamenta flava (singular, ligamentum flavum, Latin for yellow ligament) are ligaments of the spine. They connect the laminae of adjacent vertebrae, all the way from the second vertebra, axis, to the first segment of the sacrum.

Retina Additional structures, not directly associated with vision, are found as outgrowths of the retina in some vertebrate groups. In birds, the pecten is a vascular structure of complex shape that projects from the retina into the vitreous humour; it supplies oxygen and nutrients to the eye, and may also aid in vision.

Original articleIatrogenic Retinal Breaks in 25-gauge Macular Surgery The appearance of iatrogenic retinal breaks is a well-known intraoperative complication of vitreous surgery. The insertion of instruments causes traction on the adjacent vitreous base, resulting in tearing of the retina along the border of the vitreous base.

Ligaments, luxations and arthrodeses Because ruptured ligaments often do not hold sutures well so a prosthetic ligament or internal splint (figure of 8 wire between two screw heads) can protect the repair early on. Distinguish between luxation and subluxation. Luxation is complete dislocation whereas subluxation is partial dislocation.

Flexor retinaculum of the hand The flexor retinaculum is continuous with the palmar carpal ligament, and deeper with the palmar aponeurosis. The ulnar artery and ulnar nerve, and the cutaneous branches of the median and ulnar nerves, pass on top of the flexor retinaculum.

Retinal pigment epithelium Directly beneath this epithelium is the neuroepithelium (i.e., rods and cones) passes jointly with the RPE. Both, combined, are understood to be the ciliary epithelium of the embryo. The front end continuation of the retina is the posterior iris epithelium, which takes on pigment when it enters the iris. When viewed from the outer surface, these cells are smooth and hexagonal in shape.

Knee and Meniscus Anatomy The medial patellofemoral ligament (MPFL) is a continuation of the deep retinaculum and vastus medialis oblique (VMO) muscle fibers (inner portion of the quadriceps muscle) on the inside of the knee.ext to the tibia is the fibula, which runs parallel to the tibia on the outside of the leg. The patella, commonly called the knee cap, is embedded in the quadriceps and patellar tendon which articulates with the front of the femur, which forms the patellofemoral joint.

- Cooper's ligament, or the pectineal ligament, is formed from the fascia and periosteum along the superior pubic ramus. A technetium bone scan was performed and demonstrated abnormal uptake about the right superior pubic ramus and the left pubic rami. But the zone of highest von-Mises stress varied during gait from superior pubic ramus for maximum load (Figure 3a) to central inferior ilium for minimum load (Figure 3b).
