Aug 4, 2022 · Peripheral nerve blocks improve both pain control and functional outcomes following total knee arthroplasty (TKA). However, few studies have examined the effects of different peripheral nerve block protocols on postoperative range of motion. The present study assessed the impact of a single-shot femoral nerve block (SFNB) versus continuous ...

The femoral nerve may be injured in the pelvis or the thigh either directly by trauma (e.g., transection, suture ligation, diathermy or toxic injury) or indirectly by ischemia secondary to stretch or poor perfusion. The intrapelvic segment of the nerve is stated to be more vulnerable to ischemic insult . Some etiologies such as compression or perin...
During abdominal and pelvic surgery nerve compression is most commonly due to the use of self-retaining retractors, particularly ring retractors (Tables 1 and 2). Lateral retraction of the psoas major muscle may compress the nerve against the pelvic side wall or the tip of the blade may exert pressure on the nerve lateral to psoas in the region ab...
Pelvic level femoral nerve lesions tend to produce weakness of ipsilateral hip flexion and knee extension causing difficulty walking and climbing stairs. Postoperatively, this may manifest as a fall as the patient gets out of bed to walk [13, 23]. Even transient femoral neuropathies of less than 24 h duration are a concern in this respect since maj...
Treatment is partly dictated by the suspected mechanism and severity of injury . Successful treatment is reliant on prompt and accurate diagnosis and referral to a specialist; delayed treatment jeopardizes optimal recovery. Khan et al. reported a mean delay of 10 months between injury and appropriate surgical treatment in 291 patients with iatroge...
The prevention of iatrogenic femoral nerve injury requires an awareness of those situations in which it is more likely to occur and a good understanding of normal regional anatomy. Specific measures include the placement of sponges between retractor blades and psoas or if possible avoiding retraction of this muscle altogether in favor of lateral re...

Feb 24, 2020 · Femoral nerve block is a regional nerve block frequently performed after TKAs as part of a multimodal analgesia regimen [ 5 – 11 ]. Currently, there are two commonly used methods to administer femoral nerve blocks, the continuous femoral nerve block (cFNB) and single-shot femoral nerve block (sFNB).

In 721 patients, the infusion was discontinued 12 hours after surgery. There were 9 femoral nerve palsies (2 in group 1, 7 in group 2) and 8 major falls (0.7%). The overall complication rate was 1.5%, and the risk of permanent nerve injury was 0.2%.

Perioperative nerve injury (PNI) is one of the most debilitating complications after total knee arthroplasty (TKA). Although regional anesthesia (RA) techniques reduce pain and improve functional outcomes after TKA, they may also contribute to PNI.
Dec 17, 2016 · Introduction: To identify the success of pain catheters in the management of pain in nonoperatively treated femoral neck fractures (FNFs) in supplement to current multimodal protocols for end-of-life pain management. Methods: Twenty patients aged older than 50 years with FNFs were selected in a retrospective fashion at a level 1 trauma center.
