Right-sided meralgia paresthetica from lateral femoral cutaneous nerve neuroma

Meralgia Paresthetica (MP) causes outer thigh discomfort, numbness, and tingling. Compression or injury to the Lateral Femoral Cutaneous Nerve (LFCN), which gives sensory innervation to outer aspect of the thigh. It frequently gets impinged beneath the inguinal ligament resulting in in sensory impairment in the distribution of LFCN. Compression of the LFCN is a frequent cause of MP, whereas LFCN neuromas is a rare cause. This case report describes a unique case of Meralgia Paresthetica produced by a LFCN neuroma and enhances our knowledge of Meralgia Paresthetica.

Periarticular cocktail injection is more useful than nerve blocks for pain management after anterior cruciate ligament reconstruction

Background

Anterior cruciate ligament (ACL) reconstruction is commonly associated with moderate-to-severe postoperative pain. Notably, various pain control strategies, a femoral nerve block (FNB) with a lateral femoral cutaneous nerve block (LFCNB), adductor canal block (ACB) with LFCNB, or periarticular cocktail injection (PI), have been investigated. However, no studies compare the effects of FNB with LFCNB, ACB with LFCNB, and PI for pain control after ACL reconstruction. This study aimed to evaluate the impact of FNB with LFCNB, ACB with LFCNB, and PI for pain relief in the early postoperative period after ACL reconstruction.

Methods

This retrospective controlled clinical trial enrolled 299 patients who underwent primary ACL reconstruction at our hospital between April 2016 and October 2022. We categorized these cases into groups based on the use of PI (PI group), FNB with LFCNB (FNB group), and ACB with LFCNB (ACB group) for pain management. We selected 40 cases each, with matched age, sex, and body mass index (BMI) from each group, resulting in 120 cases for analysis. In the FNB and ACB groups, 0.75% ropivacaine 15 ml was injected under ultrasound guidance preoperatively. In the PI group, a mixture of 0.75% ropivacaine 20 ml, normal saline 20 ml, and dexamethasone 6.6 mg was injected half at the start of surgery and the rest just before wound closure. Patient demographics (age, sex, height, body weight, and BMI) and surgical data (the requirement for meniscal repair, operative time, and tourniquet inflation time) were analyzed. After ACL reconstruction, patients' numerical rating scale pain scores (NRS) (0-10) were recorded at 30 min and 4, 8, 12, 24, 48, and 72 h postoperatively. NRS were then compared among the three groups using analysis of variance. In addition, within each group, these data were compared between the NRS ≥7 and NRS ≤6 groups using a t-test.

Results

There were no significant differences in patient demographics and surgical data. Pain scores were significantly higher in the PI group than in the FCB and ACB groups 30 min postoperatively, but they were lower at 12, 24, 48, and 72 h postoperatively. In the FNB group, there were no significant differences in the demographic and surgical data by NRS pain score. In the ACB group, the number of men was significantly higher in the NRS ≥7 group than in the NRS ≤6 group (p = 0.015). In the PI group, tourniquet inflation time was significantly longer in the NRS ≥7 group than in the NRS ≤6 group (p = 0.008).

Conclusions

Following ACL reconstruction using a hamstring autograft, periarticular cocktail significantly reduced early postoperative pain compared with nerve block combinations.

Iliopsoas haemorrhage complicated by femoral neuropathy in patients with haemophilia: a case series report

OBJECTIVES

The study aimed to determine the incidence of femoral neuropathy in patients with haemophilia exhibiting iliopsoas haemorrhage.

METHODS

Patients with iliopsoas haemorrhage confirmed by ultrasonography or CT scan were studied retrospectively.

RESULTS

A total of 44 episodes of iliopsoas haemorrhage occurred in 20 patients with haemophilia (A17, B3). Most episodes in patients without inhibitors (14/16 = 87.5%) were adequately treated followed by prophylaxis. However, 11 of 28 episodes (39.3%) in patients with inhibitors were adequately treated and no prophylaxis was provided. An appropriate rehabilitation programme was arranged during hospitalisation and follow-up. Femoral neuropathy was observed in 28 of 44 episodes, while 16 episodes of persistent femoral neuropathy from previous bleeding were excluded. As a result, 11 of 28 episodes (39.3%) of femoral neuropathy were similarly found amongst patients with and without inhibitors. The mean time of onset and resolution of femoral neuropathy were 3.7 (1.8) and 23.4 (20.5) days after the onset of iliopsoas haemorrhage, respectively. Patients receiving inadequate and delayed replacement had a significantly higher rate of femoral neuropathy than those who received adequate and prompt replacement.

CONCLUSION

Femoral neuropathy following iliopsoas haemorrhage was common in haemophilia patients with and without inhibitors.

Iatrogenic Deep Femoral Artery Pseudoaneurysm Causing Quadriceps Paralysis: An Indication for Open Surgery in an Endovascular Era

Contemporary management of iatrogenic pseudoaneurysms is mostly performed using non-surgical techniques. Herein, we present a rare case of deep femoral artery (DFA) pseudoaneurysm with compression neuropathy, which required open repair. A 67-year-old female patient presented with increasing pain in the right groin, sensory neuropathy of the anteromedial thigh and upper leg, and quadriceps paralysis 4 days after coronary angiography via femoral puncture. Computed tomography angiography revealed a pseudoaneurysm of the DFA. The disabling compressive neuropathy warranted urgent open decompression rather than thrombin injection or endovascular therapy. Timely open evacuation of the hematoma, release of compression on the femoral nerve, and postoperative physiotherapy resulted in complete recovery of quadriceps power. The patient was pain free within 12 weeks and able to ambulate independently. This case report highlights the role of prompt open surgery for pseudoaneurysms with compression neuropathy.

Femoral neuropathy following venoarterial-extracorporeal membrane oxygenation therapy: a case report

Background

Although life-threatening complications of extracorporeal membrane oxygenation (ECMO) are well described, non-life threatening complications are less known. Herein, we report a case of femoral neuropathy (FN) due to nerve compression caused by cannula compression and deep vein thrombosis (DVT) after successful ECMO therapy, which seriously undermined one’s quality of life.

Case presentation

A 70-year old male presented to the emergency department for chest pain. The patient had cardiac arrest before percutaneous coronary intervention (PCI) and was inserted with ECMO. Although he was successfully weaned from ECMO 4 days after PCI, he consistently complained swelling, abnormal sensation, and weakness in his right lower extremity, where the cannulas were inserted. Imaging studies showed deep vein thrombosis (DVT) in his right leg, which was further treated with anticoagulants. Symptoms, however, remained after the regression of DVT. Nerve conduction study revealed femoral neuropathy, which may have been caused by ECMO cannula compression and tissue swelling.

Conclusion

The current case proposes that non-life threatening complications of ECMO therapy can seriously affect quality of life. Venous drainage distant from the arterial cannula may prevent such complications.

Idiopathic Lumbosacral Neuropathy Syndrome: Case Report

Idiopathic lumbosacral plexitis or lumbosacral radiculoplexus neuropathy is a disease characterized by nerve damage in lumbar and/or sacral plexus without trauma, mass effect or diabetic complications. A 47-year-old male patient with right groin pain and loss of right leg muscle strength is presented in this case report. Neuropathy was detected in the L4 nerve root by electromyography and magnetic resonance neurrographic imaging. The underlying cause was investigated; however, it is linked to the idiopathic outcome. Idiopathic lumbosacral neuropathy is a lumbosacral plexus disease in which no underlying pathology plays a role in causing severe pain and muscle weakness. Patients should be avoided urgently operation because of the sudden onset symptoms.

Femoral Neuropathy: A Rare Presentation of Retroperitoneal Hematoma with Review of Literature

Hematomas in close compartments and in pelvic gutters are always challenging to treat and diagnose. A young female on apixaban for recently diagnosed pulmonary thromboembolism (PE) presented to us for the complaints of right sided lower limb weakness. Neurological examination was positive for the right femoral nerve distribution deficit. Computed tomography (CECT) showed large right sided iliopsoas hematoma. Anticoagulation was stopped and was given blood transfusions with which she improved without need of any surgical evacuation. We hereby aim to enrich the understanding of our readers regarding this topic with a review of our experience and other recent publications in medical literature. It is important for the internists to be aware of varied and atypical presentations of retroperitoneal hematoma (RPH) especially following surgical/orthopaedic procedures or in association with anticoagulants and antiplatelets.

Subperiosteal hematoma of the iliac wing presenting with leg weakness in a young adult footballer

We present the case of a 17 year old football player with a 2 week history of left leg weakness and difficulty weight-bearing. Magnetic resonance imaging revealed a well-circumscribed lesion deep to the left iliacus muscle. The patient proceeded to computed tomography-guided biopsy. The likely diagnosis was that of a subperiosteal haematoma of the iliac wing, which was exerting mass effect upon the left femoral nerve resulting in leg pain and weakness. Imaging was repeated at an interval of 1 month, at which time the lesion had almost entirely resolved. Subperiosteal haematoma of the iliac bone is a rare entity but should be considered as a potential diagnosis in young adults, particularly where there is a history of trauma or recent sports injury.

[Femoral neuropathy: Haematoma in iliac muscle and a lumbar vertebral fracture]

75-year-old patient with a history of acenocumarol anticoagulated atrial fibrillation, which shows pain, functional impotence and right lower limb paresthesias after fall. Studies evidenc evertebral fracture L5 and haematoma on right iliac muscle, proceeding to surgical drainage, suspension of acenocumarol, and onset of apixaban. After treatment persisted femoral neuropathy, which not allowed complete functional recovery. DISCUSSION: Femoral neuropathy as possible cause of compressive hematoma over iliopsoas muscle or secundary to lumbar canal stenosis and contact with L4 root. In both of the misit posible to observe weakness of proximal lower limb musculature. Haematoma was suspected due to lower back pain, flank mass and hypovolemia. Handlingis based on the severity of the symptomatology, from conservative to surgical drainage to reduce sequelae and bleeding complications. Apixaban has shown a higher safety profile. Stabilization of lumbar fracture allowed partial functional recovery.

Entrapment Neuropathies of the Lower Extremity

Entrapment neuropathies in the lower limbs are a common neurologic problem and may present in any medical setting. Accurate identification and management of these nerve palsies can prevent pain, sensory loss, incoordination, and muscle weakness that may significantly affect a patient's functional mobility. In this article, the authors focus on the cause, signs and symptoms, diagnosis, and treatment of select entrapment neuropathies of the lower extremity, including palsies of the common peroneal, lateral femoral cutaneous, femoral, and posterior tibial nerves.

Spontaneous Retroperitoneal Hematoma Presenting as Femoral Neuropathy in a Patient on Low Molecular Weight Heparin Therapy

Introduction

Retroperitoneal hemorrhage has been sparsely reported with warfarin therapy. In this paper, we describe a case of spontaneous retroperitoneal hematoma causing femoral neuropathy following treatment with low molecular weight heparin.

Case Report

A 65-year-old gentleman had presented with acute onset left-sided thigh pain, paraesthesia, and weakness along with lower backache. On deeper introspection, our patient had, in the recent past, been thrombolyzed for pulmonary embolism. The clinical examination led us to suspect an acute lumbar pathology, and he was investigated on those lines. Imaging studies, however, revealed a massive retroperitoneal hemorrhage which was the cause of femoral neuropathy. In this case report, the presentation of this rare association has been discussed with special emphasis on clinical premonition in the background of anticoagulant therapy. Watchful and medical treatment yielded successful recovery at follow-up.

Conclusion

Cautious clinical assessment is needed in patients taking anticoagulant therapy. The presentation of a femoral neuropathy is often intriguing. Management options include careful observation and emergency decompression in cases of worsening neurological status.

Femoral Neuropathy Secondary to Autosomal Dominant Polycystic Kidney Disease: A Case Report

Compressive femoral neuropathy is a disabling condition accompanied by difficulty in hip flexion and knee extension. It may result from retroperitoneal hematoma or bleeding, or from complications associated with pelvic, hip surgery, and renal transplants. A 55-year-old female with autosomal dominant polycystic kidney disease presented with proximal muscle weakness in lower extremities. The patient experienced recurrent renal cyst infection, with aggravated weakness during each event. Electromyography and nerve conduction study revealed bilateral femoral neuropathy. Computed tomography and magnetic resonance images were added to further identify the cause. As a result, a diagnosis of femoral neuropathy caused by enlarged polycystic kidney was made. Cyst infection was managed with antibiotics. Renal function was maintained by frequent regular hemodialysis. While avoiding activities that may increase abdominal pressure, rehabilitation exercises were provided. Motor strength in hip flexion and knee extension improved, and was confirmed via electrodiagnostic studies.

Femoral nerve injury after nephrectomy: A case report

BACKGROUND

Femoral nerve injury is not a common complication of the abdominopelvic surgical procedures.

OBJECTIVE

To present a case of femoral neuropathy after nephrectomy.

METHODS

Case report.

RESULTS

A 71-year-old female patient with a right-sided congenital hip dysplasia developed numbness, tingling and burning pain in the right thigh and muscle weakness in the right hip after the nephrectomy surgery. Neurological examination and electrodiagnostic test revealed a femoral nerve injury. Prognosis of the femoral neuropathy was good. The quadriceps muscle weakness improved within six months.

CONCLUSION

Postoperative femoral neuropathy is an unexpected complication after total nephrectomy surgery. The prognosis is relatively good and early physical therapy can produce rapid recovery.

Intraoperative peripheral nerve injury in colorectal surgery. An update

Intraoperative peripheral nerve injury during colorectal surgery procedures is a potentially serious complication that is often underestimated. The Trendelenburg position, use of inappropriately padded armboards and excessive shoulder abduction may encourage the development of brachial plexopathy during laparoscopic procedures. In open colorectal surgery, nerve injuries are less common. It usually involves the femoral plexus associated with lithotomy position and self-retaining retractor systems. Although in most cases the recovery is mostly complete, treatment consists of physical therapy to prevent muscular atrophy, protection of hypoesthesic skin areas and analgesics for neuropathic pain. The aim of the present study is to review the incidence, prevention and management of intraoperative peripheral nerve injury.

Femoral nerve palsy with patella fracture

Femoral neuropathy may be associated with various etiologies and can cause severe walking disability. We present the case of a 25-year-old woman who underwent surgical repair for a patella fracture and complained of lower extremity pain, paresthesia, and weakness postoperatively. Electromyography and magnetic resonance imaging (MRI) revealed partial peripheral neuropathy of the left femoral nerve associated with the patella fracture. To our knowledge, this is the first reported case of femoral neuropathy associated with a patella fracture.

Femoral neuropathy and meralgia paresthetica secondary to an iliacus hematoma

Compressive femoral and lateral femoral cutaneous neuropathies from an iliacus hematoma are unusual presentation. We report a case of a 16-year-old boy who developed right femoral and lateral femoral cutaneous neuropathies as a complication of traumatic ipsilateral iliacus hematoma formation. The patient complained of numbness in the right thigh and calf as well as right leg weakness, and pain in the right inguinal area. Nerve conduction study and needle electromyography identified the neuropathies. After the electrodiagnostic studies, the pelvic bone MRI revealed a large, 9×5×4.5 cm right iliacus hematoma. As a result, diagnosis of a right iliacus hematoma compressing the femoral and lateral femoral cutaneous nerves was made, and the patient underwent an operation to remove the hematoma. Symptoms and neurological signs showed notable improvement after surgical decompression. Subsequent follow-up electrodiagnostic studies after 11 weeks demonstrated regeneration evidence.

Femoral Neuropathy due to Iliacus Muscle Hematoma in a Patient on Warfarin Therapy

Spontaneous hematomas of the iliacus muscle are rare lesions and these are seen in individuals receiving anticoagulation therapy or patients with blood dyscrasias such as hemophilia. It can cause femoral neuropathy and resultant pain and paralysis. Although there is no clear consensus for the treatment of femoral neuropathy from iliacus muscle hematomas, delays in the surgical evacuation of hematoma for decompression of the femoral nerve can lead to a prolonged or permanent disability. We report here on a rare case of a spontaneous iliacus muscle hematoma that caused femoral neuropathy in a patient who was taking warfarin for occlusive vascular disease and we discuss the treatment.

Bilateral femoral neuropathy after vaginal delivery: A case report

Epidural analgesia is frequently used for the management of labor pain in parturients. The neurologic complications of epidural analgesia are rare, but they are catastrophic when they occur. We report here on a case of bilateral femoral neuropathy in a vaginal delivery patient with epidural analgesia. The patient complained of weakness of both thighs and numbness around both knees. Neurologic examination and electromyographic study revealed that they occurred due to the delivery itself. The patient had not fully recovered at eight weeks after delivery. The declining incidence of postpartum femoral neuropathy may reflect a reduced duration of labor in accordance with modern obstetric practice, and particularly the more frequent use of Caesarean delivery. The exact etiology of postpartum femoral neuropathy is unknown, and the possible factors are direct compression of nerves that are proximal within the pelvis by either the fetal head or birthing instruments, or this malady is the result of pressure induced ischemia at the level of the inguinal ligament when the pregnant woman is in the lithotomy position.
