background: the transfer of the tibialis posterior tendon to the dorsum of foot can restore the function of the paralyzed dorsiflexor muscles of the foot and ankle. in order to reduce the wound complication in the insertion site of tendon to bone by a plantar knop we used a new method of fixation by an absorbable screw inserted dorsally. methods: we performed this operation on 15 patients in a ...

BACKGROUND Neurological injuries are a rare but devastating complication after total hip arthroplasty (THA). The purpose of this study was to retrospectively determine the frequency of nerve palsy after THA without subtrochanteric femoral shortening osteotomy in patients with a completely dislocated hip joint without pseudo-articulation between the femoral head and iliac bone. METHODS Between...

OBJECTIVES To investigate whether ocular torsion and vertical misalignment differ in the upright vs supine position in skew deviation and to compare these findings with those in trochlear nerve palsy. METHODS Ten patients with skew deviation, 14 patients with unilateral peripheral trochlear nerve palsy, and 12 healthy subjects were prospectively recruited. With subjects first in the upright p...

PURPOSE During fixation and saccades, human eye movements obey Listing's law, which specifies the torsional eye position for each combination of horizontal and vertical eye positions. To study the mechanisms that implement Listing's law, the authors measured whether the law was violated in peripheral and central unilateral sixth nerve palsy. METHODS Twenty patients with peripheral (13 chronic...

case report: we report a 44-year-old man with right femoral nerve palsy following delayed reduction of an anterior dislocation of hip. conclusion: two months after closed reduction, complete clinical recovery of right femoral nerve was achieved and the patient was able to resume his job. introduction: incidence of nerve injury in traumatic hip dislocations is up to 10 %. sciatic nerve is the mo...

Introduction: Hoarseness of voice is a very common condition and is caused by recurrent laryngeal nerve palsy. Many possible causes of unilateral vocal cord paralysis are known, including malignant or less often benign tumors, iatrogenic injury, inflammation, or post radiation fibrosis causing nerve palsy due to encasement. Cardiovocal syndrome or Ortner’s syndrome is hoarseness due to left rec...

account for approximately 3% of all biceps tendon ruptures. The two-incision repair techniques, as described by Boyd and Anderson1 in 1961, were developed to lower the risk of injury to the radial nerve and posterior interosseous nerve. Reports of posterior interosseous nerve palsy following this approach are rare.2-3 Transient posterior interosseous nerve palsies following a repair with the tw...

AIM The aim of this study is to compare the results of nerve grafting vs. common infraclavicular intraplexal nerve transfer in elbow flexion restoration. MATERIAL AND METHODS The study included 39 patients with upper brachial plexus palsy who were operated using common intraplexal nerve transfer (Oberlin procedure) and the thoracodorsal and medial pectoral nerve transfer to the musculocutaneo...

BACKGROUND Lesions in peripheral nerves are highly prevalent in the upper extremity. The present study compares different tendon transfer surgeries in patients with radial nerve palsy. METHODS Fifty patients with radial nerve palsy were randomly selected among patients who referred to Tehran 15th Khordad Hospital during 2006-2011. They were divided into two groups of 17 and 33 subjects. Sing...

PURPOSE During fixation and saccades, human eye movements obey Listing's law, which specifies the eye's torsional angle as a function of its horizontal and vertical position. Torsion of the eye is in part controlled by the fourth nerve. This study investigates whether the brain adapts to defective torsional control after fourth nerve palsy. METHODS Thirteen patients with fourth nerve palsy (1...
