purpose: to report a patient with exotropia due to medial rectus muscle entrapment as a complication of endoscopic dacryocystorhinostomy (edcr). case report: a 34-year-old female was referred with left exotropia 18 days after edcr for treatment of primary nasolacrimal duct obstruction. she had a large angle left exotropia in primary position as well as complete limitation of adduction and parti...

blow out fracture is a common disease in oculoplastics clinics. one of indication for surgical intervention is entrapment of inferior rectus muscle in the fractured site. in this article authors represent two cases with this disease who underwent surgery for the entrapment of perimuscular fascia without inferior rectus muscle involvement. the results of treatment in both cases were excellent. t...

OBJECTIVES Muscle hypertrophy is a relatively rare condition that may cause nerve entrapment syndromes. We report the case of a 14-year-old girl with unilateral hypertrophy of the abductor hallucis muscle with entrapment of the medial plantar nerve and review the literature. METHODS Computed tomography and magnetic resonance imaging revealed unilateral hypertrophy of the abductor hallucis mus...

BACKGROUND To compare the microRNA (miRNA) expression profiles in neurons and innervated muscles after sciatic nerve entrapment using a non-constrictive silastic tube, subsequent surgical decompression, and denervation injury. METHODS The experimental L4-L6 spinal segments, dorsal root ganglia (DRGs), and soleus muscles from each experimental group (sham control, denervation, entrapment, and ...

Baker's cysts are rare cause of peripheral nerve entrapment and only a few cases of tibial nerve entrapment resulting from the popliteal cyst in the calf muscle have been reported in the literature. We present a case of rheumatoid arthritis complicated by a Baker's cyst with a tibial nerve entrapment. It is important to diagnose a Baker's cyst early and to differentiate it from thrombophlebitis...

Using stable isotopic labeling of dietary fatty acids in conjunction with arteriovenous difference measurements, we have assessed the regulation of lipoprotein lipase-derived fatty acid entrapment in subcutaneous adipose tissue and forearm muscle in healthy subjects in the postprandial state. Eight volunteers fasted overnight and were then given a mixed meal containing [ 1-(13)C]palmitic acid a...

BACKGROUND The suprascapular nerve entrapment syndrome accounts for about 1-2% of all causes of shoulder pain and dysfunction. Entrapment may occur at different levels and a frequent site of compression is the suprascapular notch, the upper border of which is the superior transverse scapular ligament. MATERIAL AND METHODS We studied 5 patients with entrapment of the suprascapular nerve at the...

We report a patient with primary ulnar entrapment neuropathy in the midarm. Stimulation of multiple sites along the ulnar nerve showed a motor conduction block at a distance of 7.5-10 cm proximal to the medial epicondyle, where the nerve was compressed by the medial intermuscular septum. Anatomically, the possibility of ulnar nerve entrapment in this segment has long been suggested, and stimula...

The popliteal fossa is a narrow intermuscular space posterior to the knee joint that is bounded by biceps femoris tendon proximolaterally, semimembranosus muscle proximomedially, and medial and lateral heads of the gastrocnemius muscle distally. The popliteal artery is a continuation of the femoral artery. It begins at the opening (hiatus magnus) in the adductor magnus muscle and runs downward ...

Entrapment of the flexor digitorum profundus (FDP) is a recognized complication of paediatric both-bone forearm fractures. Although a rare complication, it is usually missed at the time of initial fracture management resulting in the need for corrective surgery. An attempted closed manipulation followed by immediate surgical correction of FDP entrapment in our hospital prompted a review of the ...
