Sciatic Nerve Lab Report

843 Words4 Pages

Introduction: The sciatic nerve is the largest and thickest nerve in the human body, formed by anterior rami of L 4, 5, S 1, 2, 3 spinal segments. It is made up of two components, the common peroneal and tibial nerves, which are held together by the connective tissue sheath. It enters the gluteal region through the greater sciatic foramen below the piriformis muscle, descends on the back of thigh and usually divides into its terminal branches at the apex of popliteal fossa1. Variations in different level of terminal division of sciatic nerve and its relations with piriformis muscle have been reported. The variations in the course of sciatic nerve may lead to clinical condition like sciatica, piriformis syndrome and coccygodynia. Hence the …show more content…

In the present study, out of 30 cadavers, 3 cadavers on right side (10%) and 2 cadavers (6.67%) on left side showed variation in relation of sciatic nerve with the piriformis muscle. Type I variation of Beaton and Anson’s classification was found in 90%, type II in 6.67% and type III in 3.33% of cadavers on right side. On left side, only two types of variations were observed, the type I in 93.33% and type II in 6.67% of cadavers. 2. Terminal division of sciatic nerve was observed at three levels – Pelvic, Gluteal and Popliteal level (apex of popliteal fossa). 3. The measured length of sciatic nerve ranged from 2 cm to 42 cm and 3 cm to 42 cm on right and left sides respectively. The breadth of sciatic nerve at its origin varied from 1 cm to 2.5 cm on both sides. The thickness of sciatic nerve varied from 0.5 cm to 2 cm and 0.5 cm to 1.3 cm on right and left sides respectively. 4. However no variation in relation with piriformis and level of terminal division was observed in foetuses. The length of sciatic nerve in foetuses varied from 7.1 cm to 8 cm on both sides. The breadth of the nerve varied from 0.2 cm to 0.35 cm on the right side and 0.19 cm to 0.3 cm on the left side. The thickness of the sciatic nerve ranged from 0.09 cm to 0.12 cm on both

    In healthy individuals, anterior rotation of the innominate occurs during extension of the freely swinging leg. When the innominate anteriorly rotates, it glides inferiorly down the short arm and posteriorly along the long arm of the SIJ. In non-weights bearing an arthrokinematic glide between the innominate and the sacrum occurs during posterior rotation of the innominate and is physiological (i.e., follows the articular surfaces). In weight bearing, the close-packing of the SIJ precludes this physiological glide. Sacral nutation produces the same relative arthrokinematic glide as posterior rotation of the innominate (inferoposterior motion of the sacrum is the same as anterosuperior motion of the innominate); sacral counternutation produces the same arthrokinematic glide as anterior rotation of the innominate (anterosuperior motion of the sacrum is the same as inferoposterior motion of the

    The carpal tunnel functions as an entrance to the palm for many tendons and median nerve (1). The median nerve is one of the five branches that make up the brachial plexus. This nerve provides motor innervation to the flexor muscles of the forearm and hand as well as muscles responsible for movements of the thumb. It also provides sensory innervation to the volar aspects of the first three digits and half of the fourth digit, the palm, and the medial region of the forearm (2). Carpal tunnel syndrome (CTS) is a common painful disorder of the wrist and hand.

  • Essay On Phantom Limb Pain Syndrome

    The other problem we will analyse is phantom limb pain syndrome, which is a pain that can be detected in the area where amputation occurred (as in the case of our patient), and there are some factors that are dangerous such as pain after surgery and amputation and, of course, the bad psychology that our patient may have (Flor, 2002). Phantom limb pain is a phenomenon of mutilation caused by this process and in these cases, can occur in many patients. Some possible ways that can cause phantom limb pain in a patient may be the various nerves that exist in sensitive parts of our body and cause the patient to experience some pain (Ehde, 2000). To improve the phantom limb pain, we can do some action, such as reducing pain.

  • Piriformis Syndrome Case Study

    Introduction: Piriformis syndrome (PS) is a neuromuscular condition with a special combination of several characteristic manifestations mainly highlighted by gluteal pain(1). Others may involve pain in the lower back area down to buttocks, paraesthesia, numbness and limitations to some weight-bearing activities like walking for long periods, standing and sitting to some degrees(1-5). Other symptoms may also include: the sciatic notch tenderness, swelling, sexual dysfunctions and splayfoot with a dominant external rotation in supine lying indicating tightness of the muscle(6). In general, four primary manifestations had the highest tendency to be found as was reported by a recent systematic review. These include: posterior buttock pain, increased sciatica symptoms with sitting, tenderness over the greater sciatic notch and positive results of Piriformis muscle tension tests

    Some nociceptive afferent input also sprouts into the Lamina II of the dorsal horn of spinal cord (which respond to noxious stimulation).which results in increased neuronal activity, expansion of neuronal receptive field and hyperexcitibility of other region. This process is called central sensitization. Sensitization of dorsal horn neuron is mediated by the increased activity of NMDA receptor and release of glutamate and neurokinins. The stump or phantom pain is evoked by repetitive stimulation of the stump the phenomenon is known as “windup phenomenon” in which there is up regulation of the receptors in the respective

    Low back pain is neither a disease nor a diagnostic entity of any sort. The term refers to pain of variable duration in an area of the anatomy afflicted so often that it is has become a paradigm of responses to external and internal stimuli (Ehrlich GE 2003). Research study on low back pain has shown that it is a common problem in general population. As seen in Western industrialized countries, back pain is one of the major health problems (R Ayiesah and D Ismail 2007).
