OBJECTIVE To compare the nerve injury and vessel disruption complicaitons in patients undergoing saphenous vein stripping using olive heads of different sizes. METHODS Big olive heads were used in group A (n=50) and small olive heads were used in group B (n=50) from the ankle to the groin; in group C (n=50), the vein was stripped in two sections; in an upward fashion by stripping the distal p...

Damage to peripheral nerves is known to contribute to chronic pain states, including mechanical and thermal hyperalgesia and allodynia. It is unknown whether the establishment of these states is attributable to peripheral changes, central modifications, or both. In this study, we used several different approaches to assess the changes in myelinated (A) and unmyelinated (C) cutaneous nociceptors...

Background. Cutting nerve during operations like saphenous vein grafting and knee joint surgery are common surgical procedures. Objective. To report cases of dermatitis at the site of neuropathy following skin incision for saphenous vein grafting and knee joint surgery. Patients and Methods. This case report work was done in the Department of Dermatology, Baghdad Teaching Hospital, during 2009-...

PURPOSE To investigate anatomic variations of neurovascular structures in the ankle and the safety margin for arthroscopic portals. METHODS 11 left and 12 right ankles from 8 female and 15 male fresh cadavers of Chinese ethnicity aged 53 to 88 (mean, 68) years were used. The ankle was standardised in a plantigrade position, zero-degree inversion, and neutral rotation. Four ankle portals, name...

The infrapatellar branch of the saphenous nerve (IBSN) is purely sensory and innervates both the anteromedial aspect of the knee and the anterior-inferior portion of the knee capsule. The IBSN arises from the saphenous nerve in the adductor hiatus before piercing the fascia lata to become subcutaneous. Infrapatellar pain syndrome (IPS), also known as an infrapatellar nerve injury, is not a wide...

The adductor canal block (ACB) is newer compartment block of the saphenous nerve, which is a branch of femoral nerve, performed at the level of lower third of the thigh so that much of the motor innervation of the quadriceps group is spared, thus preserving much of the quadriceps strength making early ambulation and rehabilitation safer. The most significant advantage of the ACB over femoral ne...

The epidermis is innervated by fine nerve endings that are important in mediating nociceptive stimuli. However, their precise role in neuropathic pain is still controversial. Here, we have studied the role of epidermal peptidergic nociceptive fibers that are located adjacent to injured fibers in a rat model of neuropathic pain. Using the Spared Nerve Injury (SNI) model, which involves complete ...

The purpose of this study was to evaluate the topography of the saphenous nerve branches and of the popliteal neurovascular bundle of knee and to establish a low risk placement position of the posteromedial knee portal (PmKP). A slice anatomy study, by using plastinated transparent knee cross-sections was performed on 12 intact right male cadaver lower limbs. The measurements were performed at ...
