Leg muscles of the monkey have been studied following partial denervation produced by surgical elimination of from 25 to 90 per cent of the axons entering the sciatic nerve from the lumbosacral plexus. The investigation included observations on function, rate and degree of muscle atrophy, and neurohistological appearance of the affected muscles. In most of the cases, from 83 to 90 per cent of t...

PURPOSE The purpose of this narrative review is to summarize the evidence derived from randomized controlled trials (RCTs) regarding approaches and techniques for lower extremity nerve blocks. SOURCE Using the MEDLINE (January 1966 to April 2007) and EMBASE (January 1980 to April 2007) databases, medical subject heading (MeSH) terms "lumbosacral plexus", "femoral nerve", "obturator nerve", "s...

BACKGROUND Pelvic cancers such as cancer of the cervix can spread locally to involve adjacent structures such as the lumbosacral plexus and the sympathetic chain. When this happens the prognosis is usually poor. An early suspicion of recurrence may result in investigation leading to earlier and better treatment. A physical sign that may be an early and only sign of recurrence is described. OB...

Diabetic lumbosacral radiculoplexus neuropathy (DLSRPN) (other names include diabetic amyotrophy) is well recognized, unlike the non-diabetic lumbosacral radiculoplexus neuropathy (LSRPN), which has received less attention. Our objective was to characterize the natural history and outcome of LSRPN and to assess whether it is similar to the diabetic variety in its symptoms, course, electrophysio...

The objective was to describe perineal electrophysiological findings and to determine their diagnostic value in a type of lumbosacral plexopathy after vaginal delivery, which only involves the lower part of the plexus (S2-S4). Consecutive female patients referred to an outpatients' urodynamic clinic were the source. Nineteen previously healthy women, 13 multiparae and six para 1, were investiga...

STUDY DESIGN Single blinded, randomized clinical trial for the evaluation of lumbosacral orthoses (LSOs) in the management of lower back pain (LBP). OBJECTIVE To evaluate the effects of two types of LSOs on self-rated disability in patients with LBP. SUMMARY OF BACKGROUND DATA LSOs are commonly used for the management of LBP, but their effectiveness may vary because of design. An inextensib...
