RESUMO
PURPOSE: Multiple nerve compression syndromes can co-occur. Little is known about this coexistence, especially about risk factors and surgical outcomes. Therefore, this study aimed to describe the prevalence of multiple nerve compression syndromes in the same arm in a surgical cohort and determine risk factors. Additionally, the surgical outcomes of concomitant treatment were studied. METHODS: The prevalence of surgically treated multiple nerve compression syndromes within one year was assessed using a review of patients' electronic records. Patient characteristics, comorbidities, and baseline scores of the Boston Carpal Tunnel Questionnaire were considered as risk factors. To determine the treatment outcomes of simultaneous treatment, patients who underwent concomitant carpal tunnel release (CTR) and cubital tunnel release (CubTR) were selected. The treatment outcomes were Boston Carpal Tunnel Questionnaire scores at intake and at 3 and 6 months after the surgery, satisfaction 6 months after the surgery, and return to work within the first year. RESULTS: A total of 7,867 patients underwent at least one nerve decompression between 2011 and 2021. Of these patients, 2.9% underwent multiple decompressions for the same upper extremity within one year. The risk factors for this were severe symptoms, younger age, and smoking. Furthermore, the treatment outcomes of concomitant CTR and CubTR did not differ from those of CubTR alone. The median time to return to work after concomitant treatment was 6 weeks. Patients who underwent CTR or CubTR alone returned to work after 4 weeks. CONCLUSIONS: Approximately 3% of the patients who underwent surgical treatment for nerve compression syndrome underwent decompression for another nerve within 1 year. Patients who report severe symptoms at intake, are younger, or smoke are at a greater risk. Patients with carpal and cubital tunnel syndrome may benefit from simultaneous decompression. The time to return to work may be less than if they underwent decompressions in separate procedures, whereas their surgical outcomes are comparable with those of CubTR alone. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Objective The aim of the present study was to describe and evaluate the initial and the long-term clinical outcome of internal neurolysis (IN) for trigeminal neuralgia (TN) without neurovascular compression (NVC). Methods A total of 170 patients diagnosed with TN were treated by posterior fossa exploration, during the period between April 2012 and October 2019. The patients were divided into two groups: Group A (50 patients)was treated by IN and Group B (120 patients) received microvascular decompression (MVD). Surgical outcomes and postoperative complications were compared between the two groups. Pain intensity was assessed by the Barrow Neurological Institute (BNI) pain intensity score and BNI facial numbness score. Pain recurrence was statistically evaluated with Kaplan-Meier analysis. Results Pain was completely relieved in 44 patients (88%) who underwent IN (group A); 3 (6%) experienced occasional pain but did not require medication (BNI 2). In group B, 113 (94%) experienced immediate pain relief after MVD. The median duration of follow-ups was 4 years (6 months to 7.5 years). In Group A, there was a meantime recurrence of 27 months in 3 patients (6%). The recurrence in Group B was of 5.8% during the follow-up period. There were no statistically significant differences in the surgical outcomes between the two groups. All patients with IN experienced some degree of numbness, 88% of the cases resolved in 6 months, on average. Conclusion Internal neurolysis is an effective, safe and durable treatment option for trigeminal neuralgia when NVC is absent.

Hemifacial spasm is typically caused by vascular compression of the proximal intracranial facial nerve. Although the prevalence of neurovascular compression has been investigated in a cohort of patients with classical trigeminal neuralgia, the prevalence and severity of neurovascular compression has not been well characterized in patients with hemifacial spasm. We aimed to investigate whether presence and severity of neurovascular compression are correlated to the symptomatic side in patients with hemifacial spasm. All patients in our study were evaluated by a physician who specializes in the management of cranial nerve disorders. Once hemifacial spasm was diagnosed on physical exam, the patient underwent a dedicated cranial nerve protocol magnetic resonance imaging study on a 3 T scanner. Exams were retrospectively reviewed by a neuroradiologist blinded to the symptomatic side. The presence, severity, vessel type, and location of neurovascular compression along the facial nerve was recorded. Neurovascular compression was graded as contact alone (vessel touching the facial nerve) versus deformity (indentation or deviation of the nerve by the culprit vessel). A total of 330 patients with hemifacial spasm were included. The majority (232) were female while the minority (98) were male. The average age was 55.7 years. Neurovascular compression (arterial) was identified on both the symptomatic (97.88%) and asymptomatic sides (38.79%) frequently. Neurovascular compression from an artery along the susceptible/proximal portion of the nerve was much more common on the symptomatic side (96.36%) than on the asymptomatic side (12.73%), odds ratio = 93.00, P < 0.0001. When we assessed severity of arterial compression, the more severe form of neurovascular compression, deformity, was noted on the symptomatic side (70.3%) much more frequently than on the asymptomatic side (1.82%) (odds ratio = 114.00 P < 0.0001). We conclude that neurovascular compression that results in deformity of the susceptible portion of the facial nerve is highly associated with the symptomatic side in hemifacial spasm.

PURPOSE: To identify the morphological patterns of suprascapular notch stenosis. METHODS: Suprascapular notch space capacity was assessed by morphometric analysis of 333 dry scapulae. Suprascapular notch parameters-superior transverse distance, middle width, depth, medial border length and lateral border length-were measured. The probable suprascapular notch stenosis was referenced by (1) comparing each obtained parameter measurement to the range of the suprascapular nerve diameter, and (2) quantifying the reduced parameters. Finally, the morphological pattern was determined based on the collective reduction of the parameters and their alignments. RESULTS: Five types of suprascapular notch based on depth to superior transverse distance ratio were identified and assessed. Type-I showed low incidence of stenosis (6/333) and low frequency within type (6/28) with potential risk of horizontal compression. Type-II showed relatively low incidence of stenosis (9/333) and low frequency within type (9/50) with undetermined pattern. Type-III showed relatively higher incidence of stenosis (47/333) but low frequency within type (47/158) with potential risk of vertical compression. Type-IV (foramen) showed low incidence of stenosis (6/333) and relatively lower frequency within type (6/26) with potential risk of encircled compression. Finally, type-V (discrete) showed relatively high incidence of stenosis (40/333) and high frequency within type (40/71) with potential risk of vertical compression. The suprascapular notch was found to be stenosed beyond its capacity to accommodate the suprascapular nerve in 49/333. Type-V is at most risk followed by Type-III. CONCLUSIONS: Suprascapular notch stenosis takes three morphological patterns: horizontal, vertical or mixed. An osteoplasty of suprascapular notch margins may be required beside the common surgical approach of the superior transverse scapular ligamentectomy.

AIM: To investigate the incidence, risk factors, and recovery of patients with meralgia paresthetica (MP) following posterior spine surgery. MATERIAL AND METHODS: Patients who underwent posterior spine surgeries in prone position at the authorsâ™ clinics were included in this study. Patients with preoperative MP were excluded. RESULTS: Among the 560 patients who underwent spine surgery in prone position, 117 (21%) had impaired sensation along the anterolateral aspect of the thigh. One hundred three of them were treated with conservative treatment, whereas 14 underwent surgery for MP. CONCLUSION: Conservative treatment is the first option for MP. Patients who do not recover with conservative treatment may undergo surgical treatment.

The aim of this study was to investigate the incidence rates and operations for carpal tunnel syndrome and ulnar and radial neuropathies in specialist care in Finland. Patients diagnosed with entrapment neuropathies of the upper extremity were identified from the Care Register for Health Care, 2007-2016. There were 81,911 cases in 54,095,070 person-years. The total crude incidence rates per 100,000 person-years among women and men were 197 and 105 for carpal tunnel syndrome, 26 and 36 for ulnar neuropathies, and 5.7 and 8.5 for radial neuropathies, respectively. Of these, carpal tunnel syndrome was operated on in 63% of women and 61% of men, ulnar neuropathy in 43% of women and 47% of men, and radial neuropathy in 11% of women and 8% of men. Incidence of carpal tunnel syndrome and ulnar neuropathies increased up to late middle age, while radial neuropathies were less common. Level of evidence: III.

INTRODUCTION: Magnetic resonance (MR) imaging is often used in diagnostic evaluation of tinnitus patients. Incidental findings like a neurovascular conflict (NVC) in the cerebellopontine angle are often found; however, the diagnostic value of this finding remains unclear. The aim of this study is to investigate whether the type or degree of compression of the vestibulocochlear nerve is of diagnostic value in patients with a NVC. METHODS: A retrospective study was performed in 111 tinnitus patients with available MR imaging between 2013 and 2015. Clinical and audiometric variables were gathered and MR imaging was reevaluated by two neuroradiologists. NVCs were analyzed using a grading system based on previous research by Sirikci et al. RESULTS:: In total, 220 ears were available for assessment. In patients with unilateral tinnitus a loop compression and an indentation of the cochleovestibular nerve were more frequent than in patients with bilateral tinnitus. However, there was no significant difference in distribution of the type of compression between tinnitus and nontinnitus ears. Patient with unilateral tinnitus had a significantly higher degree of hearing loss in the symptomatic ear, compared with the asymptomatic ear and with the bilateral tinnitus group. Also, it was found that the degree of hearing loss did not differ between the various types of compression. CONCLUSION: This study did not find a diagnostic value of specific types of compression in patients with a NVC. Although the distribution of NVC classification was different in patients with unilateral and bilateral tinnitus, there was no definite relation between the type of NVC and the presence of ipsilateral tinnitus. Also, the degree of hearing loss was not related to specific types of NVC.

BACKGROUND: Ulnar neuropathy at the elbow (UNE) is the second commonest entrapment neuropathy after carpal tunnel syndrome (CTS) and yet the laterality is not well delineated. Our aim was to establish the laterality of UNE in a large cohort of patients. METHODS: All new patients with clinical and electrodiagnostic (EDX) confirmed UNE over a 13-year period were included. We used multivariate analysis to examine potential predictors of laterality, and unilateral vs bilateral UNE. RESULTS: Of 880 cases, 61% were left-sided and 39% right-sided. These proportions did not change regardless of the handedness of the patient. Patients with bilateral UNE were much more likely to be older male and have a variety of comorbidities. CONCLUSIONS: UNE appears to be present on the left 50% more often than on the right, regardless of the patient's handedness.

INTRODUCTION: Leprosy is nowaday increasingly encountered in non-endemic countries. Nerve involvement is common. Swelling of the nerves may lead to entrapment neuropathy causing pain and neurological deficits. Delay in diagnosis and treatment may lead to loss of chance of improvement. Surgical decompression in conjunction with medical therapy allows relief of symptoms. METHODS: We present a retrospective series of 21 patients surgically treated in our center for leprosy entrapment neuropathy. We report presentation, treatment, and outcome at follow-up including a brief literature review. RESULTS: Twenty-one patients were treated for nerve entrapments in four different anatomical districts. We reported good clinical outcomes mainly in motor deficits but also in improvement of sensitive deficits and pain symptoms. We did not experience surgical complications. DISCUSSION: Although there is a lack of high-quality prospective studies comparing medical and surgical treatment of leprosy neuropathy, benefits of surgery are widely reported in series and case reports from endemic countries. There is scant literature from low-incidence countries even if leprosy incidence is nowaday increasing in these countries and will likelihood further increase in the future. Our results are in line with the literature presenting good outcomes after surgery. CONCLUSION: We believe that a precise knowledge of the pathology and its management is crucial also for physicians who work in low-incidence countries to maximize healing chances with timely diagnosis and treatment.

BACKGROUND: While high-resolution imaging is increasingly used in guiding decisions about surgical interventions for the treatment of trigeminal neuralgia, direct assessment of the extent of vascular contact of the trigeminal nerve is still considered the gold standard for the determination of whether nerve decompression is warranted. OBJECTIVE: To compare intraoperative and magnetic resonance imaging (MRI) findings of the prevalence and severity of vascular compression of the trigeminal nerve in patients without classical trigeminal neuralgia. METHODS: We prospectively recruited 27 patients without facial pain who were undergoing microvascular decompression for hemifacial spasm and had undergone high-resolution preoperative MRI. Neurovascular contact/compression (NVC/C) by artery or vein was assessed both intraoperatively and by MRI, and was stratified into 3 types: simple contact, compression (indentation of the surface of the nerve), and deformity (deviation or distortion of the nerve). RESULTS: Intraoperative evidence of NVC/C was detected in 23 patients. MRI evidence of NVC/C was detected in 18 patients, all of whom had intraoperative evidence of NVC/C. Thus, there were 5, or 28% more patients in whom NVC/C was detected intraoperatively than with MRI (Kappa = 0.52); contact was observed in 4 of these patients and compression in 1 patient. In patients where NVC/C was observed by both methods, there was agreement regarding the severity of contact/compression in 83% (15/18) of patients (Kappa = 0.47). No patients exhibited deformity of the nerve by imaging or intraoperatively. CONCLUSION: There was moderate agreement between imaging and operative findings with respect to both the presence and severity of NVC/C.

The term myelopathy defines a suffering of the spinal cord whatever the etiologies. They often represent real therapeutic emergencies and are burdened by serious functional sequelae. The aim of this work was to describe the epidemiological, clinical, and etiological aspects of all myelopathies. We have conducted a prospective and descriptive study from January 1, 2015 to December 31, 2016 at the Neurology department of the Cocody University Hospital in Abidjan. Seventy-one patients out of 1,006 were included, that is, a prevalence of 7.06%. The sex ratio was 1.7. The average age was 49 years old. HIV was associated with myelopathy in 24.7% of cases. Medullary compression syndrome was predominant. Pott's disease was the etiology of compressive myelopathies (43.9%) followed by bone metastases (26.8%). Tuberculous myelitis was the most common etiology of non-compressive myelopathies (30%). Myelites of undetermined causes account for 50% of non-compressive myelopathies.
Le terme de myélopathie définit une souffrance de la moelle épinière quelles que soient les étiologies. Les myélopathies réalisent souvent de véritables urgences thérapeutiques et sont grevées de lourdes séquelles fonctionnelles. L'objectif de ce travail était de décrire les aspects épidémiologiques, cliniques et étiologiques de toutes les myélopathies identifiées lors d'une étude prospective et descriptive qui s'est déroulée du 1er janvier 2015 au 31 décembre 2016 dans le service de neurologie du CHU de Cocody d'Abidjan. Soixante et onze patients sur 1 006 ont été inclus, soit une prévalence de 7,06 %. Le sex-ratio (H/F) était égal à 1,7. L'âge moyen était de 49 ans. Le VIH était associé à la myélopathie dans 24,7 % (17 patients) des cas. Le syndrome de compression médullaire était majoritaire. Le mal de Pott était l'étiologie la plus fréquante des myélopathies compressives (43,9 %), suivi des métastases osseuses (26,8 %). La myélite tuberculeuse était l'étiologie la plus fréquente des myélopathies non compressives (30 %). Les myélites de cause indéterminée représentaient 50 % des cas des myélopathies non compressives.

OBJECTIVE: Anterior cutaneous nerve entrapment syndrome (ACNES) is often an overlooked cause of abdominal pain. Data for pediatric patients, especially with regard to the treatment modalities are scarce. The aim of this study was to present a treatment modality of ACNES with combined local subfascial anesthetic and corticosteroid injection in a prospectively collected cohort of pediatric patients. METHODS: This was a prospective observational long-term study that included pediatric patients who were diagnosed with ACNES in a tertiary care pediatric center and who were followed-up for at least 12 months (median: 1.7 y; range: 1 to 2.7 y). All children were treated by ultrasound-guided subfascial injection of 40 mg 1% lidocaine and 4 mg dexamethasone into the rectus abdominis muscle in the place of the most severe pain (trigger point infiltration). RESULTS: The study included 38 children (28, 73.7% female; median age: 15 y). The majority of patients had pain in the lower right abdominal quadrant and were diagnosed in a median of 6 (range: 0.5 to 50) months after symptoms started. Overall, 24 (63%) patients achieved sustained symptom-free remission after a median of 1 (mean: 1.6; range: 1 to 5) trigger point infiltration during the first treatment session. Five (13%) children were surgically treated because of a lack of long-term response. Children who were surgically treated required a higher number of block applications during the first session of treatment, compared with children who were successfully treated conservatively. DISCUSSION: ACNES in children can be successfully treated by a combined local subfascial anesthetic and corticosteroid trigger point infiltration.

Recognizing the cause is essential for the management of meralgia paresthetica (MP), also known as lateral femoral cutaneous neuropathy. The aim of this study was to investigate the etiologies of MP and their influence on each other. This retrospective study enrolled referral patients with electromyographic studies who fulfilled the clinical and electrodiagnostic criteria of MP from January 2003 to December 2013. Data including age, gender, body weight, body height, occupation, and relevant medical history were collected. The etiological analysis was based on age and gender. A total of 50 patients (30 males and 20 females) were enrolled. The average age (±standard deviation) at diagnosis was 49.8±12.8years. Risk factors were identified in 29 cases (58.0%). More patients younger than 50years of age were male (73.1%, p=0.049). Peaks of age occurred between 41-50years in men and 51-60years in women. More males had a body mass index≥24kg/m2 (69.2% vs. 31.6%, p=0.012) and ≥27kg/m2 (34.6% vs. 0.0%, p=0.006). Overweight and obese patients were more vulnerable to occupational factors (50.0% vs. 19.0%, p=0.030). Only one case had diabetes mellitus (2%). Male middle-aged patients with a higher body mass index and certain occupations had an increased risk of MP. In contrast to the peak age distribution of the male patients, the frequency of developing MP was relatively even among the women at all ages. The cause was often obscure.

BACKGROUND: Neurological deficits noted immediately after childbirth are usually various obstetric neuropathies, but prospective studies are limited. The main study aim was to quantify and describe immediate postpartum neurological deficits of the lower extremity, including the buttocks. METHODS: A prospective observational study of postpartum women delivering in a single maternity hospital during three months of 2016. Among 1147 eligible women, 1019 were screened for symptoms of lower extremity numbness or weakness within eight to 32hours of delivery. Consent to undergo a detailed neurological evaluation was sought from those reporting symptoms. Risk factors were identified using logistic regression. RESULTS: Thirty five women (3.4%) reported symptoms, 27 entered the study and 23 (2.0%) had objective signs of a neurological deficit. The most common injuries were mild lumbosacral plexopathies and cluneal nerve compression. Most deficits were sensory, half of these also having a motor deficit that did not impact functionally. Based on analysis of 22 cases involving a likely intrapartum deficit, no association was found with parity, body weight, duration of labour, mode of delivery or neuraxial block. A past history of a neurological condition or a back injury was associated with odds ratios of 7.98 and 4.82 respectively. There were no neurological deficits that were clinically concerning or that were likely a complication of a neuraxial block. CONCLUSION: Transient neurological complications after labour and delivery are infrequent, mainly sensory involving multiple lumbosacral nerve roots or specific sacral cutaneous nerves, and they typically resolve within a short time.

OBJECTIVE: Patients with brain tumors often report having visual complaints. This may be due to increased intracranial pressure, compression/invasion of the optic pathway or diplopia. We assessed the incidence and the etiology of visual symptoms in patients with intracranial germinoma tumors (ICGTs). METHODS AND MATERIALS: We performed a blinded retrospective review of the clinical charts and the initial magnetic resonance imaging (MRI) of 28 patients with ICGT. Thirteen tumors were pineal, five suprasellar, seven bifocal, and further three involved either the optic nerve, the corpus callosum, or the brainstem. RESULTS: Twelve patients reported visual disturbances, seven of whom mainly experienced a decrease in vision. Two of those were initially managed as "retrobulbar neuritis" when endocrinologic symptoms prompted assessment by MRI. Involvement of the optic pathway was underestimated, and both relapsed. Field deficits were definitive sequelae, whereas visual acuity was sometimes regressive in the absence of optic atrophy. CONCLUSIONS: Compression or invasion of the optic pathway by germinomas is not a rare occurrence, and this possibility should not be overlooked when thickening or contrast enhancement is detected. Radiotherapy fields should be extended accordingly.

This is the second of a two-part series addressing symptoms, evaluation, and treatment of load carriage- related paresthesias. Part 1 addressed rucksack palsy and digitalgia paresthetica; here, meralgia paresthetica (MP) is discussed. MP is a mononeuropathy involving the lateral femoral cutaneous nerve (LFCN). MP has been reported in load carriage situations where the LFCN was compressed by rucksack hipbelts, pistol belts, parachute harnesses, and body armor. In the US military, the rate of MP is 6.2 cases/10,000 personyears. Military Servicewomen have higher rates than Servicemen, and rates increase with age, longer loadcarriage distance or duration, and higher body mass index. Patients typically present with pain, itching, and paresthesia on the anterolateral aspect of the thigh. There are no motor impairments or muscle weakness, because the LFCN is entirely sensory. Symptoms may be present on standing and/or walking, and may be relieved by adopting other postures. Clinical tests to evaluate MP include the pelvic compression test, the femoral nerve neurodynamic test, and nerve blocks using lidocaine or procaine. In cases where these clinical tests do not confirm the diagnosis, specialized tests might be considered, including somatosensory evoked potentials, sensory nerve conduction studies, high-resolution ultrasound, and magnetic resonance imaging. Treatment should initially be conservative. Options include identifying and removing the compression if it is external, nonsteroidal inflammatory medication, manual therapy, and/or topical treatment with capsaicin cream. Treatments for intractable cases include injection of corticosteroids or local anesthetics, pulsed radiofrequency, electroacupuncture, and surgery. Military medical care providers may see cases of MP, especially if they are involved with units that perform regular operations involving load carriage.

Prams and strollers are commonly used in daily childcare. We aim to study the type and severity of injuries associated with prams and strollers in an Asian population. We performed a retrospective review of children below the age of 6 who presented to a tertiary paediatric hospital in Singapore, from January 2012 to June 2015, with such injuries. There were 248 pram-related and stroller-related injuries. The median age was 12.5â months old. 69 (27.8%) sustained open wounds, 17 (6.9%) suffered fractures or dislocations and 2 children had significant head injuries. 29 patients (11.7%) sustained injuries while on stairs or escalators. Most of the injuries (197 cases, 79.4%) occurred despite adult supervision. The need for intervention was associated with older age and entrapment injuries (p<0.001). Only appropriately sized prams and strollers without exposed hinges should be used. These should not be deployed on stairs and escalators.

Peripheral nerve injuries due to sports are relatively rare but the exact incidence is not known due to a lack of epidemiological studies. Particular sports activities tend to cause certain peripheral nerve injuries including direct acute compression or stretching, repetitive compression and stretching over time, or another mechanism such as ischemia or laceration. These nerve lesions may be severe and delay or preclude the athlete's return to sports, especially in cases with delayed diagnosis. Repetitive and vigorous use or overuse makes the athlete vulnerable to disorders of the peripheral nerves, and sports equipment may cause compression of the nerves. Depending on etiology, the treatment is primarily conservative and includes physiotherapy, modification of movements and sports equipment, shoe inserts, splinting, antiphlogistic drugs, sometimes local administration of glucocorticoids or, lately, the use of extracorporeal shock waves. Most often, cessation of the offending physical activity is necessary. Surgery is only indicated in the rare cases of direct traumatic nerve injury or when symptoms are refractory to conservative therapy. Prognosis mainly depends on the etiology and the available options of modifying measures.This article is based on the publications "Reuter I, Mehnert S.

Complex regional pain syndrome (CRPS) is an extremely painful and partially disabling disease. It often occurs secondary to trauma, but also spontaneously. The emergence of CRPS has been reported following nerve root compression and/or spinal surgery, but its incidence is unknown. In this article, the present knowledge about the incidence of CRPS in the context of nerve root compression and spine surgery is reviewed and therapeutic and diagnostic consequences are discussed.

INTRODUCTION: Knowledge of morphological variations of the suprascapular region is important in the management of entrapment neuropathy and interventional procedures. The objective of this study was to collect data on the morphological features and dimensions of ossified ligaments and unusual bony tunnels of scapulae from a North Indian population. METHODS: A total of 268 adult human scapulae of unknown gender were obtained from the bone bank of the Department of Anatomy, Dayanand Medical College and Hospital, Ludhiana, Punjab, India. The scapulae were evaluated for the incidence of ossified superior transverse scapular ligaments (STSLs), ossified inferior transverse scapular ligaments (ITSLs) and bony tunnels (i.e. the bony canal between the suprascapular notch and spinoglenoid notch), found along the course of the suprascapular nerve (SSN). The dimensions of these structures were measured and noted down. Ossified STSLs were classified based on their shape (i.e. fan- or band-shaped) and the dimensions of the ossified suprascapular openings (SSOs) were measured. RESULTS: Ossified STSLs were present in 26 (9.7%) scapulae. Among the 26 scapulae, 16 (61.5%) were fan-shaped (mean area of SSO 16.6 mm(2)) and 10 (38.5%) were band-shaped (mean area of SSO 34.2 mm(2)). Bony tunnels were observed in 2 (0.75%) specimens, while an ossified ITSL was observed in 1 (0.37%) specimen. CONCLUSION: The data obtained in the present study augments the reference literature for SSN decompression and the existing anatomical databases, especially those on Indian populations. This data is useful to clinicians, radiologists and orthopaedic surgeons.
