INTERNATIONAL ORTHOPAEDICS 2024:10.1007/s00264-024-06270-w. [PMID: 39160383 DOI: 10.1007/s00264-024-06270-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 05/23/2024] [Accepted: 08/02/2024] [Indexed: 08/21/2024]
Abstract
PURPOSE Patients frequently complain of low back pain and sacroiliac joint pain (SIP) following total hip arthroplasty (THA). We hypothesized that patients with SIP would display different pelvic incidence (PI) values between standing and relaxed sitting positions, indicative of increased motion in the sacroiliac joints. METHODS In this retrospective case-control study, 94 patients who underwent unilateral THA and experienced SIP were compared with 94 control patients without SIP. SIP was confirmed through clinical tests and investigated using biplanar imaging in both standing and sitting positions. The key parameters analyzed included PI, sacral slope (SS), lumbar lordosis (LL), and limb length discrepancy (LLD). RESULTS Patients without SIP showed a mean difference in PI of -1.5° (-8°-5°) between standing-to-sitting positions, whereas those with SIP showed a difference of -3.3° (-12°-0°)(P < 0.0001), indicating more motion in the sacroiliac joint during daily activities in the latter group. Patients with SIP showed smaller change in LL between standing-to-sitting positions (mean:6.3°; range:-8°-27°) compared with those without SIP (mean:9.5°; range:-12°-28°)(P = 0.006). No significant differences were noted in functional leg length between patients with (mean:7 mm; range:0-12 mm) and without SIP (mean:7 mm; range:0-11 mm)(P = 0.973). CONCLUSIONS This study revealed significant sacroiliac joint motion in patients with SIP post-THA, as indicated by PI changes, increased posterior pelvic tilt, and reduced change in the LL. Contrary to common belief, SIP did not correlate with LLD.

Antolak SJ. The pudendal syndrome: A photo essay of nerve compression damage visualized at neurolysis in patients with chronic neuropathic pelvic pain. Neurourol Urodyn 2024. [PMID: 39032061 DOI: 10.1002/nau.25555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 06/07/2024] [Accepted: 07/08/2024] [Indexed: 07/22/2024]
Abstract
AIMS (1) To use intraoperative photographs to visualize and explain pudendal nerve compressions and anatomical variations of compression sites in patients with chronic pelvic pain. (2) To emphasize the diagnostic importance of sensory examination with a safety pin at the six pudendal nerve branches in all patients with chronic pelvic pain; the dorsal nerves (penis or clitoris; the perineal nerves; and the inferior rectal nerves). METHODS Between 2003 and 2014, "definite" pudendal neuropathy was diagnosed by examination and with two neurophysiologic tests. Neurolysis, via a transgluteal approach, was recommended only after 14 weeks of conservative care failed to adequately improve symptoms and validated symptom scores. Photographs of surgical findings were culled for their educational impact. An illustration of each photo clarifies the surgical anatomy. RESULTS The transgluteal incision permits access to pudendal anatomy and compression sites from the subpiriformis area through the interligamentary space and the pudendal canal (Alcock canal). Compressions were acquired or congenital and severity varied significantly. Pinprick sensory testing diagnoses pudendal neuropathy in 92% of both genders. Mid-nerve compression occurred commonly between the sacrotuberous and sacrospinous ligaments less frequently in the Alcock canal, but also at aberrant pathways, for example, between layers of the sacrotuberous ligament; a separate inferior rectal nerve passing through the sacrospinous ligament; at an anomalous lateral pathway posterior to the ischial spine. The results of international surgeons are discussed. CONCLUSIONS Decompression surgery was recommended in approximately 35% of patients in this practice, when pudendal neuropathy (pudendal syndrome), did not respond to two conservative levels of treatment: (1) nerve protection and medications and, (2) a series of three pudendal nerve perineural injections given at 4-week intervals. Significant nerve compression is consistently observed. Pathophysiology includes axonopathy from ischemia and demyelination. Neuropathy is readily diagnosed using a pinprick sensory examination of six pudendal nerve branches. Monitoring with the National Institutes of Health Chronic Prostatitis Symptom Index records cures >13 years.

[PMID: 38942945 DOI: 10.1007/s00464-024-10990-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 06/08/2024] [Indexed: 06/30/2024]
Abstract
BACKGROUND Pudendal nerve entrapment (PNE) is an underdiagnosed condition affecting a spectrum of pelvic functions, primarily pain, as outlined by Nantes diagnostic criteria. Although numerous surgical decompression techniques are available for its management, consensus on efficacy and safety is lacking. This study conducts a systematic review and meta-analysis to assess the efficacy and complication rates of the main surgical decompression techniques. METHODS A comprehensive literature search was conducted in PubMed®, Embase®, Web of Science®, and ClinicalTrails.gov® on 19th of April 2023. Initial screening involved title and abstract evaluation, with subsequent retrieval and assessment of abstracts and full-text articles. Studies assessing pain outcomes before and after surgical release of the pudendal nerve were included. Studies without full-text, focusing on diagnostic methods or with outcomes relating solely to LUTS, digestive symptoms, or sexual dysfunction, were excluded. Risk of bias assessement was conducted using the National Institute of Health (NIH) Study Quality Assessment tool. Studies were categorized based on three surgical techniques: perineal, transgluteal, and laparoscopic transperitoneal. Random-effects meta-analysis with subgroup analysis were used. Meta-regression analyses were conducted to investigate the influence of covariates on the observed outcomes. RESULTS Nineteen studies, comprising 810 patients, were included. The overall significant pain relief rate across all techniques was estimated at 0.67 (95% CI 0.54 to 0.78) with considerable heterogeneity (I2 = 80.4%). Subgroup analysis revealed success rate for different techniques: laparoscopic (0.91, 95% CI 0.64 to 0.98), perineal (0.69, 95% CI 0.52 to 0.82), and transgluteal (0.50, 95% CI 0.37 to 0.63). The laparoscopic technique exhibited a complication rate of 16.0%. Meta-regression indicated that patient age and median follow-up significantly influenced outcomes. CONCLUSION While comparing surgical techniques is challenging, this meta-analysis highlights important outcome differences. The laparoscopic technique appears most promising for pain improvement. However, the study also emphasizes the need for further robust, long-term research due to significant heterogeneity across studies and prevelent risk of bias. PROSPERO database: CRD42023496564.

Anat Sci Int 2023:10.1007/s12565-023-00721-x. [PMID: 37017904 PMCID: PMC10366308 DOI: 10.1007/s12565-023-00721-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Accepted: 03/31/2023] [Indexed: 04/06/2023]
Abstract
This study aimed to elucidate the origin, course, and distribution of the branches of the posterior femoral cutaneous nerve, considering the segmental and dorsoventral compositions of the sacral plexus, including the pudendal nerve. The buttocks and thighs of five cadavers were analyzed bilaterally. The branches emerged from the sacral plexus, which was divided dorsally to ventrally into the superior gluteal, inferior gluteal, common peroneal, tibial, and pudendal nerves. It descended lateral to the ischial tuberosity and comprised the thigh, gluteal, and perineal branches. As for the thigh and gluteal branches, the dorsoventral order of those originating from the sacral plexus corresponded to the lateromedial order of their distribution. However, the dorsoventral boundary was displaced at the inferior margin of the gluteus maximus between the thigh and gluteal branches. The perineal branch originated from the ventral branch of the nerve roots. In addition, the pudendal nerve branches, which ran medially to the ischial tuberosity, were distributed in the medial part of the inferior gluteal region. These branches should be distinguished from the gluteal branches; the former should be classified as the medial inferior cluneal nerves and the latter as the lateral ones. Finally, the medial part of the inferior gluteal region was distributed by branches of the dorsal sacral rami, which may correspond to the medial cluneal nerves. Thus, the composition of the posterior femoral cutaneous nerve is considered necessary when considering the dorsoventral relationships of the sacral plexus and boundaries of the dorsal and ventral rami.

Clinical usefulness of quantitative thermal sensory testing in the diagnosis and surgical treatment of women with pudendal neuropathy. Neurol Sci 2023:10.1007/s10072-023-06663-6. [PMID: 36781566 DOI: 10.1007/s10072-023-06663-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Accepted: 02/03/2023] [Indexed: 02/15/2023]
Abstract
BACKGROUND The aim of this study, conducted on women with pudendal neuropathy, was to evaluate the usefulness of quantitative thermal sensory testing (QTST) in the diagnosis, surgical management, and prognosis of the disease. METHODS The study was conducted on 90 women with pudendal neuropathy. QTST in pudendal nerve sensory innervation territory was realized before and more than 24 months after operative pudendoscopy on most patients. Cold and warm thresholds were evaluated together with a search for qualitative anomalies. The diagnostic value of QTST was assessed by comparing baseline data with normative values previously derived from 41 presumably healthy women. The effect of operative pudendoscopy on thermal sensitivity was tested by comparing preoperative and postoperative measurements. Assessment of the long-term prognostic value of QTST was based on "surgical success" defined as a VAS pain level less than 4 at least 2 years after surgery. RESULTS The existence of qualitative anomalies, like anesthesia, allodynia, dysesthesia, radiation, and dyslocalization, was clearly indicative of pudendal neuropathy. The presence of after sensation and "out of limit" values of skin temperature and cold detection threshold were also helpful for diagnosing the disease. Surgery reduced qualitative anomalies but had no positive effect on QTST thresholds. QTST measurements had no real prognostic value but other factors like constipation and abnormal perineal descent were predictive of surgical success. CONCLUSION For women with pudendal neuropathy, QTST can be considered a useful, non-invasive tool in the diagnosis, and management of the disease, but it cannot predict satisfactorily long-term outcome of operative pudendoscopy.

Abstract
Chronic pelvic pain is a common cause of pain in reproductive age women with debilitating consequences for affected women's health and quality of life. Treatment providers must be well versed in all treatment options for these patients, understanding the overlap in the management and treatment of chronic pelvic pain caused by pudendal neuralgia, myofascial pelvic pain, and vulvodynia. Pudendal blocks are a simple and quick procedure that can be performed in the office and often helps improve all the above conditions when used along with other treatment options. We review the anatomy and methodology on when and how to perform pudendal blocks in the office to better inform the general gynecologist on how to implement offering this treatment in the outpatient clinical setting.

Abstract
BACKGROUND Patients with intractable pain in the pudendal nerve distribution may benefit from pudendal neuromodulation; however, some may have previously undergone pudendal nerve entrapment surgery (PNES), potentially altering nerve anatomy and function. AIM We examined pudendal neuromodulation outcomes in patients with prior PNES. METHODS Patients with a history of PNES and quadripolar, tined pudendal lead placement for urogenital pain were reviewed. Symptoms and outcomes were collected from existing medical records. OUTCOMES Patients with pudendal neuromodulation and prior PNES were compared to patients with no prior PNES who had pudendal lead placement. RESULTS Fifteen patients with a history of 1, 2, or 3 prior PNES (n = 13, 1, and 1, respectively) were evaluated. Most (10; 67%) were female, with bilateral pain (9; 60%), and symptoms of 5-26 years. After trialing the lead, bladder symptoms and pain were improved in 8 of 12 and 9 of 14 patients, respectively, and 80% of patients (12/15) underwent permanent generator implantation. When prior PNES patients were compared to those with no prior PNES (n = 43), gender (67% vs 77% female; P = .50) and age (median 63 vs 58 years; P = .80), were similar; however, BMI differed (mean 24 vs 29; P = .008) and a lower proportion (12/15; 80% vs 42/43; 98%; P = .049) had generator implantation. Importantly, median lead implant time (48 vs 50 minutes; P = .65) did not differ between the 2 groups. CLINICAL IMPLICATIONS Pudendal neuromodulation has the potential to provide pain relief for a very difficult-to-treat population; furthermore, it does not appear that prior PNES surgery made lead placement significantly more challenging. STRENGTHS & LIMITATIONS Study strengths include being a tertiary referral center for urogenital pain and having a single surgeon perform all procedures in a regimented way. Limitations include the retrospective study design, small sample size and various approaches to PN CONCLUSION: Chronic pudendal neuromodulation can be a viable option even after prior PNES.

Abstract
Cycle use has grown rapidly over the last few years in the UK. British Cycling membership has increased threefold since the 2012 Olympic and Paralympic Games, and this is likely to rise in the wake of the Coronavirus pandemic. As urologists, day-to-day encounters with cyclists are commonplace, who may present with acute traumatic injuries or chronic overuse injuries. The aim of this literature review was to evaluate the effect of cycling on conditions presenting to the urology clinic, in particular those of raised prostate-specific antigen (PSA), haematuria and soft-tissue lesions (‘cyclist nodules’). Furthermore, the review aimed to summarize the relationship between cycling and pudendal nerve entrapment (PNE) syndromes. A PubMed search of the literature on cycling and genitourinary disorders was performed. The literature suggests no significant change in PSA levels after a bout of cycling. Age appears to have no effect on the change in PSA experienced following a bout of cycling, in particular when comparing those <50 years of age to those >50 years of age. Haematuria appears to be rare with cycling but has been described, even with stationary bike riding. It is imperative to exclude coexisting urinary-tract pathological conditions, and cycling-induced haematuria should always be considered a diagnosis of exclusion. Perineal nodular induration (‘cyclist nodules’) is a rare condition, related to pressure and repetitive micro-trauma between the perineum and saddle. Pudendal Nerve Entrapment (PNE) represents the most common bicycling-associated urogenital complaint. Numbness in the perineum, penis, scrotum or buttocks—‘genital numbness’—is the most common and most recognized symptom of pudendal compression. Despite several studies demonstrating a link between elite cyclists and erectile dysfunction, for the average cyclist riding may actually have a protective effect on sexual function.

Abstract
INTRODUCTION The terminology for female and male pelvic floor muscle (PFM) assessment has expanded considerably since the first PFM function and dysfunction standardization of terminology document in 2005. New terms have entered assessment reports, and new investigations to measure PFM function and dysfunction have been developed. An update of this terminology was required to comprehensively document the terms and their definitions, and to describe the assessment method and interpretation of the finding, to standardize assessment procedures and aid diagnostic decision making. METHODS This report combines the input of members of the Standardisation Committee of the International Continence Society (ICS) Working Group 16, with contributions from recognized experts in the field and external referees. A logical, sequential, clinically directed assessment framework was created against which the assessment process was mapped. Within categories and subclassifications, each term was assigned a numeric coding. A transparent process of 12 rounds of full working group and external review was undertaken to exhaustively examine each definition, plus additional extensive internal development, with decision making by collective opinion (consensus). RESULTS A Terminology Report for the symptoms, signs, investigations, and diagnoses associated with PFM function and dysfunction, encompassing 185 separate definitions/descriptors, has been developed. It is clinically based with the most common assessment processes defined. Clarity and user-friendliness have been key aims to make it interpretable by clinicians and researchers of different disciplines. CONCLUSION A consensus-based Terminology Report for assessment of PFM function and dysfunction has been produced to aid clinical practice and be a stimulus for research.

Abstract
Lumbar disc degeneration is defined as the wear and tear of lumbar intervertebral disc, and it is mainly occurring at L3-L4 and L4-S1 vertebrae. Lumbar disc degeneration may lead to disc bulging, osteophytes, loss of disc space, and compression and irritation of the adjacent nerve root. Clinical presentations associated with lumbar disc degeneration and lumbosacral nerve lesion are discogenic pain, radical pain, muscular weakness, and cutaneous. Discogenic pain is usually felt in the lumbar region, or sometimes, it may feel in the buttocks, down to the upper thighs, and it is typically presented with sudden forced flexion and/or rotational moment. Radical pain, muscular weakness, and sensory defects associated with lumbosacral nerve lesions are distributed on lower extremities, the buttock, lower abdomen, and groin region. A lumbosacral plexus lesion presents different symptoms in the territories of the lumbar and sacral nerves. Patients with lumbar plexus lesion clinically present with weakness of hip flexion, knee extension, thigh adduction, and sensory loss in the lower abdomen, inguinal region, and over the entire medial, lateral, and anterior surfaces of the thigh and the medial lower leg, while sacral plexus lesion presents clinical symptoms at nerve fibers destined for the sciatic nerve, common peroneal nerve, and pudendal nerve. Weakness of ankle inversion, plantar flexion, and foot drop are the main clinical manifestations of the sacral plexus lesion area. Numbness and decreased sensation are also present along the anterolateral calf and dorsum of the foot. On examination, foot eversion is usually stronger than foot dorsiflexion. The patients may also present with pain and difficulty of bowel movements, sexual dysfunction assessments, and loss of cutaneous sensation in the areas of the anal canal, anus, labia major, labia minor, clitoris, penis, and scrotum.

Grady SE, Lescun TB, Moore GE, Cooper BR, Davern AJ, Brunner TJ, Taylor SD. Ketorolac Is Not More Effective Than Flunixin Meglumine or Phenylbutazone in Reducing Foot Pain in Horses. J Equine Vet Sci 2020; 94:103204. [PMID: 33077087 DOI: 10.1016/j.jevs.2020.103204] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Revised: 07/18/2020] [Accepted: 07/20/2020] [Indexed: 10/23/2022]
Abstract
The objective was to compare the analgesic efficacy of ketorolac tromethamine (KT) and two other nonsteroidal anti-inflammatory drugs (NSAIDs), including flunixin meglumine (FM) and phenylbutazone (PB), using a heart bar shoe (HBS) model of reversible foot lameness in horses. Nine adult horses were used in a blinded, randomized, placebo-controlled crossover study. After induction of left front limb lameness using a modified HBS model, one of three NSAIDs (KT, 2.0 mg/kg IV; FM, 1.1 mg/kg IV; PB, 4.4 mg/kg IV) or saline (placebo) was administered IV as a single dose. Lameness was assessed every 30 minutes for 2 hours, then every hour up to 12 hours using both a lameness grading scale (lameness score; LS) and a body-mounted inertial sensor system (lameness locator; LL). High-performance liquid chromatography and mass spectrometry were used to measure plasma drug concentration at various time points. There was no difference in percent reduction of LS or LL value between KT and any other group, or between FM and placebo. The PB group showed a significantly higher percentage in LS reduction than the placebo and FM groups. The mean percent reduction in LL value was greater for the PB group than that for the placebo and FM groups. Plasma drug concentration was similar among horses for each drug at each time point, with drug concentrations decreasing over time. Thus, variation in plasma drug concentration did not influence lameness reduction for any drug. Ketorolac tromethamine was not superior to FM or PB in reducing lameness using a HBS model.

Abstract
Pudendal nerve (PN) entrapment is one of the most misunderstood and underdiagnosed medical conditions. It is recognized as a cause of chronic pelvic pain syndrome. However, due to the pudendal nerve’s mixed composition and complex anatomy, the presenting symptoms are varied and go beyond pain, depending on the entrapment’s nature, location and duration. We report a unique case of a young patient presenting with a urethral leak refractory to antibiotics. Patient evaluation highlighted findings suspicious of pudendal nerve entrapment. The patient was submitted to a laparoscopic transperitoneal PN neurolysis, resulting in major symptoms improvement.

Abstract
Neuropathic pain represents the extreme in maladaptive pain processing. In itself, it is a disease in which pain has become exaggerated in some combination of scope, severity, character, field, duration, and spontaneity. It is almost certainly an underappreciated, underdiagnosed cause of possible significant patient morbidity in cats. This article explores the basic mechanisms, recognition, known and suspect syndromes, and prospective treatment of feline maladaptive and neuropathic pain.

Abstract
Erectile dysfunction (ED) is increasingly becoming more common in young healthy males and is attributed mainly to psychogenic causes in these patients. Recent studies have reported that ED could be secondary to pudendal nerve or artery entrapment. This perspective assessed the efficacy of laparoscopic pudendal nerve and artery decompression in young patients suffering from refractory ED, associated to a pudendal nerve entrapment syndrome. After excluding patients with psychological ED and venous leakage, five young male patients with a history of both ED and pudendal nerve entrapment syndrome diagnosed based on the Nantes criteria were recruited. Pudendal nerve and artery release was performed using a laparoscopic transperitoneal approach. International Index for Erectile Function (IIEF-5) and erectile hardness score (EHS) improved significantly in all patients, 3 months after surgery. Pudendal nerve and artery entrapment could be therefore a reversible cause of ED in young healthy males, and its treatment by laparoscopic pudendal nerve and artery decompression seems to be safe and effective.

Abstract
In this article, we review the current uses and future directions of robotic surgery in the field of female pelvic medicine and reconstructive surgery. Pelvic surgery is ideal for the use of surgical robots, which provide improved visualization and ease of suturing deep within the pelvis. Robots have been successfully used for the treatment of pelvic organ prolapse, in procedures such as sacrocolpopexy, sacrohysteropexy, and uterosacral ligament plication. Surgeons have used the robotic successfully to treat various etiologies of female pelvic pain including fibroids, endometriosis, and nerve entrapment. Robotic repair of iatrogenic injury has been described with excellent outcomes and avoidance of conversion to open surgery in the event of an injury caused using the robotic platform. While more data is needed on this topic, there has been increasing interest in using the robot for urologic reconstruction including repair of vesico-vaginal fistula, cystectomy, augmentation cystoplasty, and continent and non-continent diversions. Recently the use of the robot has been described in the treatment of stress urinary incontinence in females, with robotic placement of an artificial urinary sphincter. While robotic surgery is associated with increased cost, the outcomes of robotic surgery in female urology are promising. More studies that properly evaluate the benefits of robotic surgery as compared to open and laparoscopic approaches are needed.

Abstract
Male chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is represented by a heterogeneous group of symptoms that can cause an important impairment of daily quality of life for patients. Diagnosis of CP/CPPS is often not clear and treatment can be challenging, as it varies according to the different causative factors and derived symptoms. Differently from approaches used in the past, the diagnosis and subsequent treatment rely on separating this entity from chronic bacterial prostatitis and considering it as a multifactorial disease. Autoimmunity and inflammation, myofascial tenderness, neuroinflammation, and psychological causes have been clearly related to this disease, and therefore CPPS should not only be considered as related to benign prostatic enlargement. A multitude of different symptoms related to urinary, genital, rectal, and perineal areas can be attributed to this condition and therefore should be routinely investigated in patients, as well as possible differential diagnoses which can cause the same symptoms, such as pudendal nerve entrapment syndrome. The aim of this narrative review is to focus on CPPS after an infectious cause has been excluded.

Abstract
The article considers the main causes of the occurrence of pudendal neuralgia. The criteria for diagnosing this state are described in detail. We present basic methods of treatment of pudendal neuralgia starting with comprehensive preservative treatment (physical therapy, medication, blockade), which in most cases are effective. And in case of its ineffectiveness or relapse of the pain syndrome, issues of conduction of pulsed RF-frequency therapy of the nerve are examined. Currently, the possibility of using hyaluronic acid preparations, botulinum toxin for the treatment of sexual neuropathy, as well as cryoanalgesia is being studying. The surgical decompression of the sexual nerve is possible in case of inefficient conservative treatment.

Abstract
The sacro-iliac joint (SIJ) located at the transition between the spine and the lower limbs is subjected to major shear forces. Mobility at the SIJ is very limited but increases during pregnancy and the post-partum period. Familiarity with the anatomy and physiology of the SIJ is important. The SIJ is a diarthrodial joint that connects two variably undulating cartilage surfaces, contains synovial fluid, and is enclosed within a capsule strengthened by several ligaments. This lecture does not discuss rheumatic or inflammatory diseases of the SIJ, whose diagnosis relies on imaging studies and blood tests. Instead, it focuses on micro-traumatic lesions. Micro-trauma causes chronic SIJ pain, which must be differentiated from hip pain and spinal pain. The diagnosis rests on specific clinical provocation tests combined with a local injection of anaesthetic. Findings are normal from radiographs and magnetic resonance imaging. Non-operative treatment with exercise therapy and stretching aims primarily to strengthen the latissimus dorsi, gluteus, and hamstring muscles to increase SIJ coaptation. Other physical treatments have not been proven effective. Radiofrequency denervation of the dorsal sensory rami has shown some measure of efficacy, although the effects tend to wane over time. Patients with refractory pain may benefit from minimally invasive SIJ fusion by trans-articular implantation of screws or plugs, which has provided good success rates.

Abstract
Understanding the etiology of and evolving research on intra- and extra-articular hip complaints requires comprehensive diagnosis and management of the spectrum of posterior hip diseases. Interest in posterior hip disorders has increased in recent years as new studies and theories have emerged regarding the disease process. Although most of the differential diagnoses around the posterior hip have traditionally been considered uncommon, recent reports suggest that these complaints have instead been commonly overlooked. Failure to identify the cause of posterior hip pain in a timely manner can increase pain perception, deteriorate the patient's hope, and consequently affect quality of life. Posterior hip pain could be differentiated as intrapelvic and extrapelvic, and differential diagnosis is made based on a comprehensive history, physical examination, and imaging studies. Plain radiography, CT, MRI, 3T MRI, and imaging-guided injection tests are usually necessary for accurate diagnosis. Surgical intervention, whether endoscopic or open, is required for patients with long-standing symptoms for whom nonsurgical treatment has been unsuccessful and who have experienced temporary relief of their symptoms after injection. Orthopedic surgeons are uniquely trained in understanding the anatomy, biomechanics, clinical evaluation and treatment of all five layers of the hip.

Abstract
In recent times, there has been an increased awareness of high-grade proximal hamstring injuries, many of which are now being managed surgically. Yet, surgical treatment of these injuries is challenging and carries potential risks of serious neurologic complications. Indeed, it is likely that postoperative neurologic complications are under-recognized. As such, knowledge of the intimate anatomic relation of the pudendal nerve and other neural structures around the proximal hamstring is essential and should provide a road map for safer and more successful surgery.

Abstract
INTRODUCTION Pudendal nerve entrapment syndrome (PNE) is characterised by the presence of neuropathic pain in the pudendal nerve (PN) territory, associated or not with urinary, defecatory and sexual disorders. Surgical PN decompression is an effective and safe alternative for cases when conservative treatment fails. The aim of this study is to describe the first robot-assisted pudendal neurolysis procedure performed in our country. MATERIAL AND METHODS We describe step by step the technique of robot-assisted laparoscopic neurolysis of the left PN performed with intraoperative neurophysiological monitoring on a 60-year-old patient diagnosed with left PNE. RESULTS The procedure was performed satisfactorily without complications. After 24h, the patient was discharged from the hospital. We observed a 50% reduction in pain measured using the visual analogue scale 2 weeks after the procedure, which remained after 10 weeks of the neurolysis. CONCLUSIONS Robot-assisted neurolysis of the PN constitutes a feasible and safe approach, enabling better visualisation and accuracy in the dissection of the PN. Intraoperative neurophysiological monitoring is useful for locating the PN and for detecting intraoperative changes after the release of the nerve.

Abstract
Introduction: Perineal pain is multifactorial in nature. Gynaecological consultation is the first point of contact in females with perineal pain for diagnosis and treatment. Case description: Three females above 60 years presented with non-radiating perineal pain and bladder disturbance. Magnetic resonance imaging revealed severe L5 S1 dural compression, which was released by posterior laminectomy. Patients felt relief in perineal pain, though bladder symptoms persisted for several months. Conclusion: Sacral roots compression leading to pain along pudendal nerve distribution may present with cauda equina symptoms with pain radiating to legs. Awareness of this condition can prevent the delay and lead to better prognosis after the surgery.

Abstract
A good understanding of cutaneous nerve entrapment syndromes is important for physicians to provide early and accurate diagnosis and treatment. These syndromes have traditionally been managed with analgesics, antidepressants or antiepileptic medication but this approach is often inadequate and causes frequent adverse medication effects. With early diagnosis and treatment, many nerve entrapment syndromes can be successfully managed with physical, non-pharmacological approaches including stretches, exercises and physiotherapy.

Abstract
Pudendal neuralgia is being increasingly recognized as a cause of chronic pelvic pain, which may be related to nerve injury or entrapment. Due to its complex anatomy and branching patterns, the pudendal nerve abnormalities are challenging to illustrate. High resolution 3 T magnetic resonance neurography is a promising technique for the evaluation of peripheral neuropathies. In this article, the authors discuss the normal pudendal nerve anatomy and its variations, technical considerations of pudendal nerve imaging, and highlight the normal and abnormal appearances of the pudendal nerve and its branches with illustrative case examples.

Abstract
Avoidant/restrictive food intake disorder (ARFID) is a diagnosis in diagnostic and statistical manual of mental disorders-5 (DSM-5) manifested by persistent failure to meet nutritional and/or energy needs. Pudendal nerve entrapment (PNE) often causes pelvic discomfort in addition to constipation and painful bowel movements. Current literature on ARFID is sparse and focuses on the pediatric and adolescent population. No association between PNE and ARFID has been described. We present a case of ARFID in an adult male with PNE resulting from subsequent scarring from testicular cancer surgery. The patient's gastrointestinal symptoms due to PNE caused significant food avoidance and restriction subsequently leading to severe malnourishment. Clinicians should be aware that distressing gastrointestinal symptoms arising from a secondary disease process such as PNE might lead to dietary restriction and food aversion. More research is needed for proper screening, detection, and treatment of ARFID. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2017; 50:84-87).

Abstract
OBJECTIVE The purpose of this study was to present a narrative review of the literature of musculoskeletal causes of adult hip pain, with special attention to history, physical examination, and diagnostic imaging. METHODS A narrative review of the English medical literature was performed by using the search terms "hip pain" AND "anterior," "lateral," and "posterior." Additionally, specific entities of hip pain or pain referral sources to the hip were searched for. We used the PubMed search engine through January 15, 2016. RESULTS Musculoskeletal sources of adult hip pain can be divided into posterior, lateral, and anterior categories. For posterior hip pain, select considerations include lumbar spine and femoroacetabular joint referral, sacroiliac joint pathology, piriformis syndrome, and proximal hamstring tendinopathy. Gluteal tendinopathy and iliotibial band thickening are the most common causes of lateral hip pain. Anterior hip pain is further divided into causes that are intra-articular (ie, labral tear, osteoarthritis, osteonecrosis) and extra-articular (ie, snapping hip and inguinal disruption [athletic pubalgia]). Entrapment neuropathies and myofascial pain should also be considered in each compartment. A limited number of historical features and physical examination tests for evaluation of adult hip pain are supported by the literature and are discussed in this article. Depending on the clinical differential, the gamut of diagnostic imaging modalities recommended for accurate diagnosis include plain film radiography, computed tomography, magnetic resonance imaging, skeletal scintigraphy, and ultrasonography. CONCLUSIONS The evaluation of adult hip pain is challenging. Clinicians should consider posterior, lateral, and anterior sources of pain while keeping in mind that these may overlap.

Abstract
Pelvic pain due to chronic pudendal nerve (PN) compression, when treated surgically, is approached with a transgluteal division of the sacrotuberous ligament (STL). Controversy exists as to whether the STL heals spontaneously or requires grafting. Therefore, the aim of this study was to determine how surgically divided and unrepaired STL heal. A retrospective evaluation of 10 patients who had high spatial resolution 3-Tesla magnetic resonance imaging (3T MRI) exams of the pelvis was done using an IRB-approved protocol. Each patient was referred for residual pelvic pain after a transgluteal STL division for chronic pudendal nerve pain. Of the 10 patients, 8 had the STL divided and not repaired, while 2 had the STL divided and reconstructed with an allograft tendon. Of the 8 that were left unrepaired, 6 had bilateral surgery. Outcome variables included STL integrity and thickness. Normative data for the STL were obtained through a control group of 20 subjects. STL integrity and thickness were measured directly on 3 T MR Neurography images, by two independent Radiologists. The integrity and thickness of the post-surgical STL was evaluated 39 months (range, 9-55) after surgery. Comparison was made with the native contra-lateral STL in those who had unilateral STL division, and with normal, non-divided STL of subjects of the control group. The normal STL measured 3 mm (minimum and maximum of absolute STL thickness, 2-3 mm). All post-operative STL were found to be continuous regardless of the surgical technique used. Measured at level of Alcock's canal in the same plane as the obturator internus tendon posterior to the ischium, the mean anteroposterior STL diameter was 5 mm (range, 4-5 mm) in the group of prior STL division without repair and 8 mm (range, 8-9 mm) in the group with the STL reconstructed with grafts (p<0.05). The group of healed STLs were significantly thicker than the normal STL (p<0.05). We conclude that a surgically divided STL will heal spontaneously and will be significantly thicker after healing.

Abstract
PURPOSE To evaluate the safety and efficacy of percutaneous CT-guided cryoablation of the pudendal nerve for the treatment of refractory pudendal neuralgia. MATERIALS AND METHODS Eleven patients were selected to undergo percutaneous CT-guided cryoablation of the pudendal nerve based on established diagnostic criteria. Brief Pain Inventory questionnaires were administered prior to the procedure, during the immediate 24 h post procedure, and 45 days and 6 months following the procedure. RESULTS Prior to treatment, the average level of pain on a scale from 0 (no pain) to 10 (worst pain imaginable) was 7.6, with pain described as "burning" (80%), "pulling" (37.5%), "crushing" (50%), "pressure" (84.5%), "throbbing" (50%), "knife-life" (52%), and "other" (60%). At 24 h, 45 days, and 6 months post-treatment, pain intensity dropped to 2.6, 3.5, and 3.1, respectively (p < 0.005). There were no procedure-related complications. CONCLUSIONS CT-guided percutaneous cryoablation may represent a safe and efficacious option for selected patients with refractory pudendal neuralgia.

Laparoscopic pudendal nerve decompression and transposition combined with omental flap protection of the nerve (Istanbul technique): technical description and feasibility analysis. Surg Endosc 2013; 28:925-32.

Abstract
BACKGROUND We aimed in this study to investigate the efficacy of laparoscopic pudendal nerve decompression and transposition (LaPNDT) in the treatment of chronic pelvic pain due to pudendal neuralgia. Pudendal nerve entrapment (PNE) between the sacrospinous and sacrotuberous ligaments is the most frequent etiology. We describe the technical details, feasibility, and advantages of a laparoscopic approach in patients with PNE. METHODS Consecutive patients (n = 27) with a diagnosis of PNE underwent LaPNDT with omental flap protection in an effort to prevent re-fibrosis around the nerve in the long term. The degree of pain and pain impact were evaluated pre- and postoperatively using the visual analog pain scale (VAS) and the Impact of Symptoms and Quality of Life. RESULTS The mean (± standard deviation [SD]) follow-up of the 27 patients was 6.8 ± 4.2 months; 16 of the 27 were followed-up for more than 6 months. The mean (SD) operation time was 199.4 ± 36.1 (155-300) min, and the mean estimated blood loss was 39.7 ml. All patients were ambulated on the first postoperative day, and the mean (SD) hospitalization time was 2.1 ± 1.0 (1-6) days. The mean VAS scores of 27, 23, 16, and 6 patients were 1.5, 1.4, 1.6, and 2.0, postoperatively, at the first, third, sixth, and twelfth months (p < 0.0001). A more than reduction in VAS score (>80 %) was achieved in 13 of the 16 patients (81.2 %) who were followed-up for more than 6 months. CONCLUSIONS LaPNDT seems a feasible surgical modality for cautiously selected patients with PNE. In addition, using an omental flap for protection of the nerve is one of the most important technical advantages of laparoscopy. As a minimally invasive surgery, the laparoscopic approach can be technically feasible, with its promising preliminary results in the treatment of PNE. With further analysis, in the future it may open new frontiers for pudendal nerve neuromodulation as a new treatment modality in some intractable functional problems of the genitourinary tract.

Abstract
BACKGROUND Pudendal neuralgia is a cause of chronic, disabling, and often intractable perineal pain presenting as burning, tearing, sharp shooting, foreign body sensation, and it is often associated with multiple, perplexing functional symptoms. CASE REPORT We report a case of a 40-year-old man presenting with chronic pelvic pain due to pudendal nerve entrapment and successfully treated with palmitoylethanolamide (PEA). CONCLUSION PEA may induce relief of neuropathic pain through an action upon receptors located on the nociceptive pathway as well as a more direct action on mast cells via an ALIA (autocoid local injury antagonism) mechanism. As recently demonstrated in animal models, the present case suggests that PEA could be a valuable pharmacological alternative to the most common drugs (anti-epileptics and antidepressants) used in the treatment of neuropathic pain.

Abstract
OBJECTIVE Nerves of the pelvic plexus and lower abdominal wall can lead to chronic neuralgias owing to a variety of causes, including iatrogenic injury, trauma, tumors, and primary nerve entrapment. Differentiating among the various neural etiologies can be a challenging task. Here, we present a large series of patients who underwent surgical treatment of these nerves, with an emphasis on diagnostic and therapeutic considerations. METHODS Between 1970 and 2006, the senior authors (DGK and DHK) surgically treated 264 cases of neuralgia of the pelvic plexus and nerves. A retrospective analysis of the patients' history, physical, diagnostic examinations, and follow-up was performed. RESULTS Twenty-five cases of solely ilioinguinal neuralgia and 24 cases of combined ilioinguinal neuralgias were treated. Of these, iatrogenic injury was the most common etiology. One hundred forty-five patients underwent surgical exploration for either femoral nerve injury (119 patients) or lateral femoral cutaneous compression (26 patients). Seventy-five percent of patients had femoral nerve injuries attributable to trauma (iatrogenic versus penetrating injuries), and the remaining 25% of patients had cystic masses or tumors. Fifty-two masses of the pelvic plexus were treated, including neurofibromas (68%), schwannomas (18%), malignant nerve sheath tumors (5%), and non-neural sheath tumors (9%). CONCLUSION Effective surgical management of these complex neuralgias depends on a solid understanding of the surgical anatomy and proper diagnosis. Electromyography and local anesthetic blocks not only can provide insight into the diagnosis but also have predictive value in assessing which patients may benefit from neurectomy or neurolysis.
