BACKGROUND The distal saphenous nerve is commonly known to provide cutaneous innervation of the medial side of the ankle and distally to the base of the great toe. We hypothesize that the saphenous nerve innervates the periosteum of the medial malleolus and joint capsule. METHODS Five fresh limbs were dissected and the saphenous nerve was traced distally with magnification. The medial malleol...

Following traumatic peripheral nerve injury reinnervation of denervated targets may be achieved by regeneration of injured axons and by collateral sprouting of neighbor undamaged axons. Experimental models commonly use sciatic nerve injuries to assess nerve regeneration and neuropathic pain, but behavioral tests for evaluating sensory recovery often disregard the pattern of hindpaw innervation....

In this study the behavioral effects of sectioning the saphenous nerve at the time of application of the loose ligature and the effect of a selective ?1-adrenergic antagonist for two weeks after tying ligatures was examined. Male Sprague-Dawley rats were used in this study. Animals were divided into six groups: Sham-operated, sciatic nerve ligation (CCI), saphenous nerve section (Saph), CCI + S...

BACKGROUND Saphenous nerve neuropathy is one of the causes of chronic pain of the knee. Blockade of saphenous nerve under sonographich guide has been used for controlling pain in recent years. The goal of this study was to evaluate the effect of saphenous nerve block for controlling pain in patients with chronic knee pain. METHOD Thirty five patients with chronic knee pain referred to Amir Al...

Conflicting data exist regarding the anatomical relationship of the saphenous and infrapatellar nerves at the adductor canal and the location of the superior foramen of the canal. Therefore, the authors performed a cadaveric study to detail the relationship and course of the saphenous and infrapatellar nerves and the level of the superior foramen of the canal. The adductor canal and subsartoria...

Wake Forest School of Medicine 73 Background: For ultrasound-guided saphenous nerve blockade within the adductor canal, the location of the saphenous nerve relative to the superficial femoral artery may be important for continuous blockade or low-volume, diagnostic block. Currently, there are inconsistencies in the literature and anatomy textbooks as to the anatomic relationship of these two st...

OBJECTIVE To present 2 cases of entrapment of the saphenous nerve at the adductor canal affecting the infrapatellar branch, and to provide insight into the utilization of nerve tension testing for the diagnosis of nerve entrapments in a clinical setting. RATIONALE Saphenous nerve entrapments are a very rare condition within today's body of literature, and the diagnosis remains controversial. ...

BACKGROUND Blockade of the saphenous nerve is often used for surgeries below the knee. Depending on the approach, success rates vary widely ranging from 33% to 88%. In this prospective volunteer study, we compared 2 ultrasound-guided techniques, the modified vastus medialis and perifemoral saphenous nerve block with a below the knee field block. METHODS Twenty volunteer adults, in a single-bl...

Neuropathies involving the brachial plexus, phrenic, recurrent laryngeal, and saphenous nerves, as well as the sympathetic chain are complications of cardiac surgery. The reported frequency of nerve injuries varies from 1.5% to 24% for the brachial plexus and 10% to 60",,6 for the phrenic nerve (1-5). Neuropathies of the recurrent laryngeal, lower limb (saphenous) nerves, and the sympathetic ch...

BACKGROUND Endoluminal laser ablation is now considered the method of choice for treating greater saphenous vein insufficiency. General anesthesia and peripheral nerve blocks with sedation have the risk of post-procedural delay in discharge and prolonged immobilization with the risk of deep vein thrombosis. The main pain experienced by patients during the procedure is during the laser ablation ...
