The characteristics and clinical course of all PNIs are summarized in table 3. Peripheral nerve blockade was not correlated with risk for PNI (OR, 0.97). 1. A total of 173 potential cases of PNI were initially identified from the Mayo Clinic Total Joint Registry. Pathological spontaneous…. Tourniquet-induced nerve injuries have been reported in the literature, but even if electromyography abnormalities in knee surgery are frequent, only two cases of permanent femoral nerve palsies have been reported, both after prolonged tourniquet time. By using a homogeneous surgical population (i .e ., TKA) with extended postoperative follow-up, we assessed the interaction between the risk for PNI imposed by RA techniques and that imposed by the surgery itself. 2009 Feb. 91(2):622-3. Study 2 (9 months). Femoral nerve injury is a rare, yet serious complication following the anterior approach for THA. However, in rare situations when PNI occurs, complete recovery may be less likely if it develops after peripheral nerve blockade. It is responsible for hip bending and knee extension. Peripheral nerve blockade was performed in 3,883 patients (31%) for supplemental postoperative analgesia. Therefore, even trained abstractors will not be able to identify those events that were either clinically present and not documented by the surgeon or anesthesiologist or documented more than 3 months after surgery but occurring during the immediate postoperative period. 2016 Sep;24(9):2948-2952. doi: 10.1007/s00167-015-3582-z. Privacy, Help Scand J Rheumatol 1983; 12:201–5, Nercessian OA, Ugwonali OF, Park S: Peroneal nerve palsy after total knee arthroplasty. Relatively high rates of persistent hypoesthesia (3%), weakness (2.2%), and persistent paresthesia (1.5%) were identified. 1992;8(2):215–227. -. Left femoral nerve. 2016. Many times nerve issues after surgery are temporary, for example, many patients have nerve problems after surgery that only last for a few weeks to months (2,3). There were no sex differences in the incidence of PNI (OR, 1.11 [female vs . Eight patients (32%) had a neurologic deficit in a distribution unrelated to the peripheral nerve block (e.g ., peroneal nerve injury after femoral nerve blockade). Complete neurologic recovery may be less likely in patients that underwent peripheral nerve blockade (OR, 0.37; 95% CI, 0.15–0.94; P = 0.03). Mononeuropathy usually means there is a local cause of damage to a single nerve. Int J Rehabil Res 2007; 30:333–7, Welch MB, Brummett CM, Welch TD, Tremper KK, Shanks AM, Guglani P, Mashour GA: Perioperative peripheral nerve injuries: A retrospective study of 380,680 cases during a 10-year period at a single institution. Table 1. @SarahGen-- Absolutely, knee nerve damage can lead to all of these. !4 weeks post surgery, i am beginning to have some return of the quadriceps which keeps the knee from buckling. Seven patients (28%) had injuries in a similar anatomic distribution to the peripheral nerve block (e.g ., proximal sciatic nerve injury after proximal sciatic nerve blockade). This is a major nerve in the leg. Injury to the infrapatellar branch of the saphenous nerve (IPS) is not uncommon after knee surgeries and trauma, yet the diagnosis and treatment of IPS neuralgia is not usually taught in pain training programs.

This page was updated by Dr Barrie Lewis on 29th October, 2018. Wang HY, Yuan MC, Pei FX, Zhou ZK, Liao R. J Orthop Surg Res. There is a femoral nerve and a sciatic nerve. It is possible that transient neurologic events (i.e ., short-term deficits) may have been underreported within the current study as well. Intraoperative anesthesia included general anesthesia in 44%, neuraxial anesthesia in 45%, and combined neuraxial/general anesthesia in 8% of patients. Epub 2014 May 17. Finally, the multicenter study design may have once again introduced a lack of standardization in anesthesia and surgical practices, both of which are limitations not seen within a single-center study design. Case description Finding the optimal control level of intraoperative blood pressure in no tourniquet primary total knee arthroplasty combine with tranexamic acid: a retrospective cohort study which supports the enhanced recovery strategy. Discussion. Six months after surgery, 5 patients (25%) achieved maximal neurologic recovery, all having reported complete recovery. Patients with PNI who underwent peripheral nerve blockade were less likely to have complete neurologic recovery (OR, 0.37; P = 0.03). We report a case of a 58-year-old woman who underwent surgical treatment of a patella fracture. See this image and copyright information in PMC. ... we performed a clinical neurological examination and an electrophysiological study before surgery to exclude pre‐existing femoral neuropathy. After Mayo Clinic Institutional Review Board approval and written informed consent were obtained, all patients aged at least 18 yr who underwent elective TKA at Mayo Clinic from January 1, 1988, to July 1, 2007, were retrospectively identified using the Mayo Clinic Total Joint Registry. The clinical course of each PNI was recorded, including: (1) date of onset, (2) terminology used to describe the deficit (numbness, weakness, neuropathy, neurapraxia, nerve palsy, nerve injury, paresthesia, foot drop, other), (3) presence of neurologic deficit at hospital discharge, (4) diagnostic evaluation by neurology consultation and/or electromyography study, (5) date of neurologic recovery, (6) date of last follow-up, (7) time to recovery (less than 1 month, 1–3, 3–6, 6–12 months, or more than 12 months), and (8) degree of neurologic recovery (complete [returned to baseline neurologic status], partial [deficit improved, but symptoms still exist], or none [deficit unchanged from initial description]). Incidence, outcome, and risk factors in sedated or anesthetized patients. Tourniquet-induced nerve injuries have been reported in the literature, but even if electromyography abnormalities in knee surgery are frequent, only two cases of permanent eCollection 2020 Jun. The femoral nerve stretch is performed with the patient prone. If they last longer than a few months, then they’re placed into the permanent nerve damage category … Vastus medialis. Although regional anesthesia (RA) techniques reduce pain and improve functional outcomes after TKA, they may also contribute to PNI. Anesthesia and Analgesia. Surveys that use physician self-reports introduce reporting bias, whereas short-term data collection (e.g ., 48 hours after surgery) could fail to recognize late-onset deficits, introducing a timing bias. Type of intraoperative anesthesia was also not associated with PNI (OR, 1.10 [neuraxial vs . Prevention and treatment information (HHS). Even if it is not a serious injury, it still takes a long time. These associations are consistent with a previous report by Horlocker et al .5While younger patients may be more likely to undergo bilateral procedures, no association was found between age and bilateral surgical procedures. In all cases, two-tailed P  values less than or equal to 0.05 were considered statistically significant. Reg Anesth Pain Med 2009; 34:534–41, Asp JP, Rand JA: Peroneal nerve palsy after total knee arthroplasty. The neurological lesion after hip surgery is one of the most horrible complications for both surgeon and patient ( 3 ). Left femoral nerve. Surg Radiol Anat. Purpose. Peripheral nerve blockade improves analgesia after total knee arthroplasty, but whether it increases peripheral nerve injury in this setting is not known. Fertil Steril . Anesthesiology 2002; 97:1274–80, Auroy Y, Narchi P, Messiah A, Litt L, Rouvier B, Samii K: Serious complications related to regional anesthesia: Results of a prospective survey in France. During the 7-year period from 2008 to 2016, 1756 patients underwent primary THA with a direct anterior approach by a single senior surgeon for end-stage osteoarthritis. 2006. Kornbluth ID, Freedman MK, Sher L, Frederick RW. Purpose. A total of 13,252 patients underwent 19,058 elective TKA procedures during the 20-yr study period. PNI was not associated with peripheral nerve blockade (odds ratio [OR], 0.97) or type of anesthesia (OR, 1.10 [neuraxial vs. general]; OR, 1.82 [combined vs. general]). It supplies the back of the thigh, side of the lower leg and much of the foot. “Neuropathy after surgery can significantly affect postsurgical outcomes,” says Nathan Staff, M.D., Ph.D., Mayo Clinic neurologist. Plast Reconstr Surg Glob Open. Table 3. Femoral neuropathy is an infrequent complication after surgeries or obstetric procedures and is most commonly reported after direct trauma ( 1, 2 ). The primary outcome variable was the presence of a new sensory or sensorimotor deficit documented within 3 months of the surgical date. Iatrogenic femoral nerve injury: a systematic review. Unable to load your collection due to an error, Unable to load your delegates due to an error. 17-4, B). The remaining 24 cases (25%) of PNI were limited to sensory deficits without associated motor dysfunction. For bilateral procedures, the longest of the two tourniquet times was used in the analysis. Here we report 2 cases of femoral neuropathy immediately following pelvic surgery. After multivariable logistic regression, age (OR, 0.70 [per decade]; P < 0.001) and tourniquet time (OR, 1.28 [per 30-min increment]; P = 0.003) were found to be associated with risk for PNI (table 2). Ninety-seven cases of PNI were identified among 12,329 patients. Femoral nerve block (FNB) has been proposed for pain control following anterior cruciate ligament (ACL) reconstruction. -, Horlocker TT, Hebl JR, Gali B, et al. Electromyography and nerve conduction study showed a severe axonal neuropathy of the left femoral nerve, without clinical remission after several months.

How Much Oxygen Does the Human Lung Consume? Assessment is made of the effectiveness of femoral nerve block, administered either before or after surgery, in supplementing postoperative analgesia for knee joint (anterior cruciate) reconstruction surgery. Pattern at full effort reveals significant loss of motor units. Overall, 69.7% of TKA surgical procedures were unilateral primary; 15.5%, unilateral revision; and 14.8%, bilateral. Careers.

Nineteen patients (76%) developed sensorimotor neurologic deficits, 6 (24%) developed sensory deficits only. Of the 25 patients that had PNI after peripheral nerve blockade, 11 (44%) had complete neurologic recovery, and 14 (56%) had partial recovery. The Mayo Clinic Total Joint Registry was queried and appropriately coded all 40 patients as experiencing a “nerve-related complication” or a “peroneal/sciatic nerve palsy” after surgery, suggesting a high degree of sensitivity in capturing the proposed clinical endpoint (i.e ., PNI). [Medline] . Although there are electromyography studies revealing femoral nerve lesions after tourniquet use, there are few case reports of femoral nerve lesions and none of saphenous nerve injury after use of a tourniquet for knee surgery. The Mayo Clinic Total Joint Registry is a previously validated21and comprehensive repository of data collected for each joint replacement surgery performed at Mayo Clinic since 1969. Incidence of perioperative nerve injury (PNI) after total knee arthroplasty (TKA) and the proportion of patients receiving peripheral nerve blockade during 20-yr study period. Clin Orthop 1985; 193:160–7, This site uses cookies. Elderly persons with muscle atrophy and flaccid, loose skin might be in risk for iatrogenic nerve injury secondary to tourniquet. Most cases of PNI (73 [75%] of 97) were combined sensorimotor deficits. If a nerve gets damaged during knee surgery, … 2006 Dec;92(8):768-77. doi: 10.1016/s0035-1040(06)75945-1. -, Aho K, Sainio K, Kianta M, Varpanen E. Pneumatic tourniquet paralysis. Welch et al .4reported a 10-yr retrospective review of more than 380,000 consecutive patients undergoing all types of surgical procedures and anesthetics from a single institution. The objective of this study was to test the hypothesis that PNI risk differs among patients according to RA use during TKA. 2016 Oct-Dec;32(4):424-430. doi: 10.4103/0970-9185.168174. Study…, Vastus medialis. Damage to any one nerve, such as the femoral nerve, is called mononeuropathy. Femoral nerve block (FNB) is an analgesic technique that blocks sensation to the knee to reduce pain following surgery. Please enable it to take advantage of the complete set of features! Although these studies have reported results on a large number of patients undergoing RA, clinical outcomes were collected using self-reporting surveys from a small, voluntary proportion of French anesthesiologists (15 and 6% in 1997 and 2002, respectively).16,17This methodology leaves to chance the possibility of underreporting, response bias, and a lack of standardization between anesthesia and surgical practices across several institutions. 1). Patient demographics (sex, date of birth, height, weight), date of surgery, side of surgery (right, left, bilateral), surgeon, total tourniquet time, and type of surgery (primary, revision) were recorded from the Mayo Clinic Total Joint Registry. Potential cases of PNI were identified using a comprehensive list of complications documented within the Mayo Clinic Total Joint Registry. The primary outcome variable was the presence of a new PNI documented within 3 months of the procedural date. Postoperative femoral neuropathy is an uncommon complication occurring after pelvic surgery. 2011 Oct;33(8):649-58. doi: 10.1007/s00276-011-0791-0. Overall, the majority (62%) of neurologic deficits completely resolved during the median follow-up of 5.1 yr, with an additional 36% of patients reporting partial recovery. Femoral nerve stretch is a neural tension test used to place tension on the femoral nerve to diagnose nerve root compression of the midlumbar nerve roots (L2-L4) (see Fig. Peripheral nerve blockade was performed in 0.5, 0.2, 19.8, and 82.5% of TKA patients during the designated time periods, respectively, 1988–1992, 1993–1997, 1998–2002, and 2003–2007 (P < 0.001). Therefore, the known functional and clinical benefits of RA for patients undergoing TKA14can be achieved without increasing the risk of neurologic injury. Reda W, ElGuindy AMF, Zahry G, Faggal MS, Karim MA. While we cannot make any formal conclusions about the association of PNI severity and peripheral nerve blockade, it is possible that complete recovery may be less likely when a neurologic deficit develops in the setting of peripheral nerve blockade. Patients frequently experience severe chronic pain following knee operations.

Rev Chir Orthop Reparatrice Appar Mot. In contrast, only 5 (21%) of 24 patients experiencing isolated sensory deficits had documentation of the neurologic deficit before hospital dismissal. Anesthesiology 1997; 87:479–86, Brull R, McCartney CJ, Chan VW, El-Beheiry H: Neurological complications after regional anesthesia: Contemporary estimates of risk. therapy.33 There is some controversy over whether or not femoral nerve blocks lead to long term quadriceps weakness, prolonging the return to a preoperative level of functioning. Together, these limitations make it difficult to assemble a cohort of patients experiencing PNI after undergoing a single surgical procedure. These differences in study methodology may account, in part, for the seemingly higher incidence of PNI identified in the current study of 79 per 10,000 (0.79%) in patients undergoing TKA at a single institution. Femoral nerve damage causes severe pain in the buttock and upper anterior thigh and lower inner leg pain. Knee Surg Sports Traumatol Arthrosc. Each of the above variables was independently associated with risk for PNI.

However, complete recovery may be less likely in the rare instance when a neurologic deficit develops in the setting of peripheral nerve blockade. Because the use of prolonged (i.e ., more than 48 hours) postoperative continuous RA techniques may obscure symptoms of PNI, this study design may have also increased the risk of underreporting overall PNI frequency. Twenty patients (21%) required more than 1 yr to achieve maximal neurologic recovery, with 10 reporting complete recovery. If a PNI does occur, most patients will experience complete or partial recovery of their neurologic deficit within 12 months of surgery. There are two basic kinds of health care professional mistakes that can lead to nerve damage during surgery: a physical error by a surgeon or assisting staff, and an error during administration of anesthesia. Symptoms of Nerve Damage After Surgery A severe burning pain, also known as neuropathic pain, is sometimes experienced after a nerve surgery. Study 2 (9 months). Because the use of peripheral nerve blockade has become more common during the past decade, the 20-yr study period was divided into quartiles to assess the incidence of PNI over time (fig. The names and medical record numbers of 40 patients with known PNI after joint replacement surgery were prospectively collected during the past 10 yr by one of the authors (J.R.H.). All analyses were performed using SAS (version 9.1; SAS Institute, Inc., Cary, NC). Overall incidence of PNI was 0.79% (95% CI, 0.64-0.96%).

Age, sex, body mass index, type of procedure, tourniquet time, type of anesthesia, and use of peripheral nerve blockade were evaluated as potential risk factors for PNI using multivariable logistic regression. 8600 Rockville Pike Data collection was limited to 5 days postoperatively with the exception of those patients in whom a prolonged neurologic deficit was already documented. Femoral, saphenous nerve palsy after tourniquet use: a case report. Study 3 (18 months). It is important to recognize the limitations of the current study. Accessibility It passes infero-laterally through the psoas muscle and emerges from its lateral border. One study of 27,004 primary hip arthroplasties found only two patients with complete and one with partial femoral nerve palsy[1]. In the remaining 68% of patients, the peripheral nerve block was in an anatomic distribution that was congruent with the location of the nerve injury. The incidence of neurologic complications after peripheral nerve blockade has also been reported by Capdevila et al .20In that investigation, neurologic complications associated with 1,416 continuous peripheral nerve catheters were prospectively examined in a multicenter study design. The biggest symptoms of nerve damage after surgery are usually numbness, tingling, burning, or muscle weakness or atrophy. However, patients with an isolated sensory deficit were more likely to have complete neurologic recovery compared with patients with sensorimotor deficits (73 vs . PNI Incidence after TKA by Patient and Surgical Characteristics (N = 12,329), Table 2. It may sometimes be difficult to walk or stand for long periods of time.

Some cases of PNI may not become apparent until several days or even weeks after a surgical event.8,9,11,25Therefore, complete case ascertainment cannot be assured. All cases of PNI were subsequently verified (or excluded) after manual chart review by one of the authors (H.P.S.). Journal of Bone and Joint Surgery B. The greater risk for PNI associated with increased tourniquet inflation times may be exacerbated in patients undergoing bilateral procedures, but no association was found between tourniquet time and bilateral surgical procedures. Motor unit action potentials highly polyphasic, low voltage, and short duration. Patients with preexisting sensory or motor deficits (e.g ., diabetic peripheral neuropathy, multiple sclerosis) or deficits first appearing more than 3 months after surgery were excluded.
