Trochleitis is inflammation of the superior oblique tendon trochlea apparatus characterized by localized swelling, tenderness, and severe pain. This condition is an uncommon but treatable cause of periorbital pain. The trochlea is a ring-like apparatus of cartilage through which passes the tendon of the superior oblique
The external oblique functions to pull the chest downwards and compress the abdominal cavity, which increases the intra-abdominal pressure as in a Valsalva maneuver.It also performs ipsilateral (same side) side-bending and contralateral (opposite side) rotation: the right external oblique would side-bend to the right and rotate to the left, and vice versa.
Symptoms can often be reproduced by maneuvers such as performing sit-ups or crunches. Pain can also be elicited with the patient in a "frog position", in which the patient is supine with knees bent and heels together. [7] The exact lesion may differ, but common pathologic findings at operation are: torn external oblique aponeurosis
Symptoms: Pain, dysthesias, paresthesias, and hyperesthesia on the anterolateral thigh [2] Causes: Anything that compresses the lateral femoral cutaneous nerve, such as tight fitting clothes at the waist and injuries. [3] Risk factors: Obesity, pregnancy, diabetes, middle-age [3] Diagnostic method: Clinical examination and patient history [2]
Cadaveric studies showed that the sternalis muscle has a mean prevalence of around 7.8% in the population, [7] with a slightly higher incidence in females. [1] The prevalence ranges from 0.5% to 23.5%, depending on the subpopulation [8] — it has been proposed that the possible reason for the sizable range could be the fact of the existence of small, ill-defined, or tendinous fibres which ...
Congenital fourth nerve palsy is a condition present at birth characterized by a vertical misalignment of the eyes due to a weakness or paralysis of the superior oblique muscle. Other names for fourth nerve palsy include superior oblique palsy and trochlear nerve palsy. [ 1 ]
The linea alba (Latin for: white line) is a strong fibrous midline structure [1] of the anterior abdominal wall [2] situated between the two recti abdominis muscles (one on either side).
The conjoint tendon (previously known as the inguinal aponeurotic falx) is a sheath of connective tissue formed from the lower part of the common aponeurosis of the abdominal internal oblique muscle and the transversus abdominis muscle, joining the muscle to the pelvis. It forms the medial part of the posterior wall of the inguinal canal.
