Meralgia paresthetica is a compressive neuropathy of the lateral femoral cutaneous nerve. Surgery is the gold standard for severe cases. However, no high-quality evidence exists on which strategy is best: decompression or neurectomy. Data of a consecutive series of 52 patients treated for meralgia paresthetica over 25 years (1997–2022) were retrospectively collected from medical records and telephone interviews. In total, 27 women and 25 men were operated on; 11 patients had iatrogenic meralgia paresthetica. Decompression was performed on 47 patients, and neurectomy in 8 cases (5 primary neurectomies plus 3 failed neurolysis). Out of the patients who underwent decompression, 41 (87.2%) benefited from the treatment; 3 had pain relief, but no benefit on paresthesia; and 3 reported pain persistence. The latter required neurectomy to resolve symptoms. The eight patients who underwent neurectomy experienced symptom relief but had an obvious anesthetic area persisting over years. Complications were rare (3.8%): a groin hematoma in the post-operative course and an inguinal herniation 6 months after surgery. Surgery, be it neurolysis or neurectomy, offers excellent results with low risks. Decompression has been proven to be adequate in almost all patients, avoiding the side effects of neurectomy. The latter should be confined to failed decompression or to iatrogenic meralgia. [ABSTRACT FROM AUTHOR]

Background: A 26-year old male testicular cancer survivor presented for Chiropractic care with a primary complaint of intermittent thigh pain. Intervention: The patient underwent a course of subluxation-based Chiropractic care during which he was checked and adjusted using Advanced Bio-Structural Correction Technique. Outcome: Despite a singular presenting concern of intermittent thigh pain from an four-year-old injury, he returned numerous other positive outcomes he attributed to Chiropractic. This presents numerous questions as to the body's state of adaptability even years after cancer, and the role Chiropractic may play in building up this adaptability again over time.

BACKGROUND: Anterior thigh pain is frequent in rugby players, and hematomas are common. Most occur due to trauma; however, if swelling occurs with no mechanism of injury, these should always be investigated. CASE PRESENTATION: A 17-year-old male presented with a 6-month history of left anterolateral thigh pain and swelling with no mechanism of injury. Examination revealed that the area was hot to touch, no wounds were visible, and the patient reported no night pain or fever. He was urgently referred where an x-ray showed no findings, and then subsequently discharged. On recommendation from the original referring clinician, an ultrasound scan was ordered, which showed a 4.5-cm foreign body causing an infection. OUTCOME AND FOLLOW-UP: Subsequent surgery removed a twig with thorns from the area. The pain was relieved, and he returned to rugby 3 weeks later with no further complications. DISCUSSION: This case is a unique presentation of anterolateral thigh pain and highlights the importance of referral and follow-up when things do not fit a clinical picture. [ABSTRACT FROM AUTHOR]

Total hip arthroplasty (THA) for hip disorders helps to alleviate pain and improve active daily life. When determining the effects of medical therapy and the subsequent clinical results, patient quality of life (QOL) also needs to be assessed. Recently, patient-reported outcomes (PRO) have become important as evaluation criteria. This study aimed to evaluate patient QOL and various PRO between different types of cementless stems and to clarify the relationship between PRO and stem-cortical bone contact. The study comprised 138 consecutive patients undergoing cementless THA for hip osteoarthritis. We assessed three different types of PRO: the Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire (JHEQ), patient's joint perception, and peri-hip articular joint pain (PHAP). We measured the state of contact between femur and implant by density mapping. No significant difference was noted in PRO between stem types based on the JHEQ and patient's joint perception. PHAP occurred more frequently in the patients with a taper wedge stem versus a fit-and-fill stem. In both groups, distal contact was associated with PHAP but not with JHEQ results and patient's joint perception. The difference in PHAP between the two stem types groups was significant, with postoperative PHAP being higher with the taper wedge stem because of the more distal contact between the taper wedge stem and femur cortical bone.

Objective: To evaluate the clinical utility of selective magnetic resonance neurography-(MRN)-guided anterior femoral cutaneous nerve (AFCN) blocks for diagnosing anterior thigh neuralgia. Materials and methods: Following institutional review board approval and informed consent, participants with intractable anterior thigh pain and clinically suspected AFCN neuralgia were included. AFCN blocks were performed under MRN guidance using an anterior groin approach along the medial sartorius muscle margin. Outcome variables included AFCN identification on MRN, technical success of perineural drug delivery, rate of AFCN anesthesia, complications, total procedure time, patient-reported procedural experiences, rate of positive diagnostic AFCN blocks, and positive subsequent treatment rate. Results: Eighteen MRN-guided AFCN blocks (six unilateral and six bilateral blocks) were performed in 12 participants (6 women; age, 49 (30–65) years). Successful MRN identified the AFCN, successful perineural drug delivery, and AFCN anesthesia was achieved in all thighs. No complications occurred. The total procedure time was 19 (10–28) min. Patient satisfaction and experience were high without adverse MRI effects. AFCN blocks identified the AFCN as the symptom generator in 16/18 (89%) cases, followed by 14/16 (88%) successful treatments. Conclusion: Our results suggest that selective MR neurography-guided AFCN blocks effectively diagnose anterior femoral cutaneous neuralgia and are well-tolerated. [ABSTRACT FROM AUTHOR]

Background: The trochanteric bursa (TB) is an anatomic structure, which is dissected during posterior/lateral hip approaches in Total Hip Arthroplasty (THA). Some surgeons prefer to simply resect the bursa as they believe that it may be responsible for postoperative lateral trochanteric pain (LTP). Others advocate that this tissue acts as a buffer minimizing friction between soft tissue and bone, and therefore its repair may prevent LTP after THA. Aim: The purpose of this prospective randomized controlled trial was to compare the clinical results of either resecting or repairing the TB during posterior approach THA. Methods: Forty-two patients with primary hip osteoarthritis undergoing THA via a posterior hip approach were randomly assigned to two groups; Group A, or TB resection group and Group B, or TB repair group. All patients in both groups were evaluated postoperatively in terms of hip function, measured by the Harris Hip Score (HHS), at 6 weeks, 3 months, 6 months, and 12 months after surgery, as well as LTP during daily routine activities and lying on the operative side. Results: Forty patients completed the study. Postoperative difference in terms of leg length and femoral offset was similar among the two groups (P = 0.467 and P = 0.39, respectively). At 6 weeks, patients in Group B had higher HHS (P = 0.052) and experienced less LTP when lying on the operative side (P = 0.046) but not during activities (P = 0.759). Thereafter, all functional parameters measured had comparable values in both groups. Subgroup analysis failed to identify any correlation between high offset stems and LTP. Conclusion: TB repair in posterior approach THA improves hip functional recovery as well as patients' ability to lie on the operative side during the early postoperative period.

Purpose: Short-stem prostheses in hip arthroplasty have emerged as an alternative to conventional stems, especially in younger patients. The purpose of this study was to compare functional and radiological results of a short metaphyseal fitting cementless stem versus a conventional stem implant, in patients younger than 60 years. Methods: All patients operated from January 2006 to April 2013 were included, obtaining a minimum follow-up of 7 years. Harris Hip Score (HHS) and SF-36 (quality of life) questionnaires were applied and the presence of "thigh pain" was specifically assessed. We also compared complication rate, revision rate and average prosthesis survival. Femoral stress shielding (Gruen scale), stem subsidence, varus-valgus tilt and implant stability (Engh scale) were also compared. Results: A total of 101 short-stem and 74 conventional arthroplasties were included, with an average follow-up of 9.82 (7–14) years. HHS functional score and SF-36 were excellent in both implants and no significant difference between them (p > 0.05) was found. However, "thigh pain" was present in 7 patients with conventional stems and none with short-stems (p < 0.001). The survival rate at 13 years was 99%, for both implants, and no significant differences were found between them (χ2(2) = 0.178; p = 0.673). Conventional stems had stress shielding at the greater trochanter in 72% of the cases and 43% at the calcar, being statistically superior (p < 0.001) to the stress shielding observed in the short stems. Conclusion: According to our results, this short-stem seems to allow preservation of bone stock, with decreased stress shielding and also a lower incidence of thigh pain compared to conventional stems. Level of Evidence: Level III retrospective comparative study. [ABSTRACT FROM AUTHOR]

Background: Thigh pain following a well-fixed total hip arthroplasty (THA) remains problematic and a source of patient dissatisfaction. The purpose of this study is to evaluate if the development of distal femoral cortical hypertrophy (DFCH) is associated with postoperative thigh pain after THA. Methods: All patients who underwent an uncomplicated primary THA via a direct anterior approach with the Taperloc Microplasty (Zimmer Biomet, Warsaw, IN, USA) implant between 2011 and 2015 were mailed a pain drawing questionnaire. Radiographs were reviewed at 1 year minimum to determine cortical thickness change from immediate post-op. Thigh pain was compared to DFCH. 293 patients were included in the study. Results: Mean follow-up was 3.2 years. A total of 218 hips (74%) had cortical hypertrophy in Gruen zone 3 and 165 hips (56%) had cortical hypertrophy in Gruen zone 5. 52 hips (18%) had ⩾25% cortical hypertrophy in zone 3 and 91 hips (31%) had ⩾25% cortical hypertrophy in zone 5. A total of 44 patients (15%) reported anterior thigh pain and 43 patients (15%) reported lateral thigh pain. Development of DFCH in either Gruen zone 3 or 5 was not associated with anterior or lateral thigh pain. Stem size was positively correlated with zone 3 hypertrophy and inversely related to zone 5 hypertrophy. Thigh pain was not associated with patient age, gender, activity level or stem size. Conclusions: The development of distal femoral cortical hypertrophy after THA with a short stem implant was high, but not associated with patient-reported anterior or lateral thigh pain.

Objective: To describe and illustrate the magnetic resonance imaging (MRI) anatomy of the anterior femoral cutaneous nerve (AFCN) and a new technique for cryoanalgesia of the AFCN for long-term analgesic treatment of recalcitrant AFCN-mediated neuropathic pain.Materials and Methods: Using a procedural high-resolution MRI technique, we describe the MRI anatomy of the AFCN. Three patients (mean age, 48 years; range, 41-67 years) with selective nerve block-verified recalcitrant AFCN-mediated anterior thigh pain were enrolled to undergo cryoanalgesia of the AFCN. Procedures were performed under MRI guidance using clinical wide-bore MR imaging systems and commercially available cryoablation system with MR-conditional probes. Outcome variables included technical success, clinical effectiveness including symptom relief measured on an 11-point visual analog scale, frequency of complications, and procedure time.Results: Procedural MRI allowed to successfully demonstrate the course of the AFCN, accurate cryoprobe placement, and monitoring of the ice ball, which resulted in technically successful iceball growth around the AFCN in all cases. All procedures were clinically effective, with median pain intensity decreasing from 8 (7-9) before the procedure to 1 (0-2) after the procedure. The cryoanalgesia effect persisted during a 12-month follow-up period in all three patients. No major complications occurred. The average total procedure time was 98 min (range, 85-125 min).Conclusion: We describe the MRI anatomy of the AFCN and a new technique for cryoanalgesia of the AFCN using MRI guidance, which permits identification of the AFCN, selective targeting, and iceball monitoring to achieve long-term AFCN-mediated neuropathic pain relief.

Case: A 70-year-old female patient underwent total hip arthroplasty (HA) using a stem cemented line-to-line without centralizer. Postoperatively, she complained of load-dependent thigh pain. Conventional radiographs identified cortical overload because of a distal cement mantle discontinuity at the level of the stem's tip, confirmed by single-photon emission computed tomography/computed tomography scan (SPECT/CT). After cement-in-cement revision using a stem with centralizer, pain ceased rapidly. The cortical overload disappeared, as confirmed on a following SPECT/CT performed for low back pain. Conclusion: In HA, the stem's tip may cause overload on the bone's cortex if the cement mantle is incomplete. Implanting a stem with centralizer avoids or cures this. [ABSTRACT FROM AUTHOR]

Purpose: Short tapered stem placement has been extensively employed in total hip arthroplasty (THA). Suboptimal fixation tends to cause postoperative complications, such as thigh pain. However, it remains unclear whether poor seating/alignment of short tapered stems contributes to thigh pain. In this study, we retrospectively examined the factors that might be associated with thigh pain. Methods: Medical records of 230 patients who had undergone THAs at our hospital were reviewed retrospectively. All patients received the same mediolateral (ML) short tapered femoral stems. The association between thigh pain and patients' demographics, radiographic findings, or the type of fitting of the femoral stems was investigated. Results: In our cohort, 68 patients (27.8%) presented with thigh pain. Among 203 type I fit patients, 62 (30.5%) developed thigh pain, while only 6 out of 43 (12.2%) type II fit patients had thigh pain, with the differences being statistically significant (x2 = 6.706, p = 0.01). In addition, hip anteroposterior radiographs exhibited that the stem angulation (mean 2.52°), the variation in angulation (mean 1.32°), and the extent of femoral stem subsidence (mean 0.29 cm) were greater in patients with thigh pain than in their counterparts without thigh pain (all p < 0.05). Conclusion: Malalignment and improper seating of short tapered stems could be at least one of the reasons for post-THA thigh pain. The distal contact between the stem tip and the medial femoral cortex might result in thigh pain. Our study suggested that distal implant contact should be avoided, and stem alignment should be meticulously performed in the placement of ML short tapered femoral stems for THA.

Purpose: The occurrence of thigh pain following cementless total hip arthroplasty (THA) may be dependent on multiple factors, which may differ with design of the prosthesis. Thus, this study aimed to investigate the frequency of thigh pain following cementless THA using a short, tapered-wedge stem to identify risk factors for thigh pain. Methods: This retrospective cohort study analysed 222 joints of patients who underwent THA with a short, tapered-wedge stem. Thigh pain was evaluated using a questionnaire during each follow-up visit, and the clinical and radiographic assessments were compared. Results: Thigh pain occurred in 37 patients (16.7%) during the follow-up period. The pain started two to 24 months after THA. Multivariate analysis demonstrated that higher University of California, Los Angeles, activity rating (odds ratio 7.2; 95% confidence interval (CI) 3.0–17.2); Dorr type C femoral bone shape (odds ratio 1.5; 95% CI 1.1–2.0); and stem tip-cortical bone contact (odds ratio 8.2; 95% CI 2.3–29.4) were significant risk factors of thigh pain following THA. Post-operatively, cortical hypertrophy at Gruen zone 4 was significantly found in patients with thigh pain (p value = 0.032). Conclusion: Risk factors of pain following THA with short, tapered-wedge stem were high activity level, Dorr type C femoral bone shape, and stem tip contacting the distal bone surface. Moreover, post-operative cortical hypertrophy at the distal stem tip significantly increased the incidence of thigh pain. Therefore, we must pay attention to the aforementioned factors to avoid post-operative thigh pain when using a short, tapered-wedge stem. [ABSTRACT FROM AUTHOR]

Background: Although reported results on short stems sound very promising, the occurrence of distal femoral cortical hypertrophy is often observed. The aim of the present study was to report 5-year survival data of a commercially available trochanter sparing short stem and investigate the clinical impact of distal femoral cortical hypertrophy on the outcome. Methods: 123 total hip arthroplasties were performed on 120 patients from April 2008 to May 2010 (mean age 62, range 29–89 years; 71 hips from male patients, 58%). Clinical and radiological data were collected preoperative, at 6 weeks, 1, 2, 3, and 5 years postoperative to assess the outcome. Radiographs taken immediately postoperative as well as 1 and 5 years postoperative were used to identify and assess cortical hypertrophy. Results: 1 stem had to be revised due to aseptic loosening, resulting in a Kaplan-Meier survival analysis with endpoint for stem revision of 99.2% (95% Confidence Interval 94.1–99.9) at 5 years. 96 radiological and 95 clinical follow-ups were analysed 5 years postoperative. 68 (71%) hips showed distal femoral cortical hypertrophy after 5 years. The average Harris Hip Score and Oxford Hip Score improved 33 (standard deviation (SD) 15.1, range 2–70), 18 (SD 12.1, range -10–43) points, respectively. Overall 16% of the patients reported thigh pain, unrelated to the presence of cortical hypertrophy. Discussion: This short stem shows an excellent 5-year survival rate and good clinical outcome despite a high incidence of cortical hypertrophy. However, the question of the mechanism of load transfer arises. [ABSTRACT FROM AUTHOR]

Objective. This article presents an evidence-based algorithm to assist primary care providers with the diagnosis and management of lateral hip and thigh pain in older adults. It is part of a series that focuses on coexisting pain patterns and contributors to chronic low back pain (CLBP) in the aging population. The objective of the series is to encourage clinicians to take a holistic approach when evaluating and treating CLBP in older adults. Methods. A content expert panel and a primary care panel collaboratively used the modified Delphi approach to iteratively develop an evidence-based diagnostic and treatment algorithm. The panelists included physiatrists, geriatricians, internists, and physical therapists who treat both civilians and Veterans, and the algorithm was developed so that all required resources are available within the Veterans Health Administration system. An illustrative patient case was chosen from one of the author's clinical practices to demonstrate the reasoning behind principles presented in the algorithm. Results. An algorithm was developed which logically outlines evidence-based diagnostic and therapeutic recommendations for lateral hip and thigh pain in older adults. A case is presented which highlights the potential complexities of identifying the true pain generator and the importance of implementing proper treatment. Conclusions. Lateral hip and thigh pain in older adults can contribute to and coexist with CLBP. Distinguishing the true cause(s) of pain from potentially a myriad of asymptomatic degenerative changes can be challenging, but a systematic approach can assist in identifying and treating some of the most common causes.

Morel-Lavallée lesion is an unusual clinical entity which was first described by the French surgeon Maurice Morel-Lavallée in 1853. These lesions result from peeling off the surfaces between the fat tissue and the muscular fascia. During this decomposition, the rupture of small vessels may cause an effusion full of necrotic blood, lymph and fat cells. In prolonged cases, these lesions may become increasingly painful, leading to be confused with other diagnosis such as sciatalgia, piriformis syndrome, trochanteric bursitis or soft tissue tumor. Herein, we present a-65-year-old female case who had pain in the right thigh for one year and was referred to our clinic with radicular pain. [ABSTRACT FROM AUTHOR]

Objectives: Inside-out tension-free vaginal tape obturators for the cure of female stress incontinence can cause postoperative thigh pain. The aim of the present study was to analyze and compare the mid-term outcomes of two tension-free vaginal tape obturator procedures. Methods: Patients diagnosed with urinary stress incontinence were enrolled to undergo a tension-free vaginal tape obturator sub-mid urethral tape operation either by de-Leval's method or by Flam's modification. Peri- and postoperative data were collected by uninvolved researchers and analyzed. Follow up was 36 months. Results: Overall, 161 patients were included in the study. Cure and complication rates were similar between the two treatment groups. Postoperative thigh pain was significantly more frequent and lasted longer in the de-Leval group compared with the Flam group (31.9% vs 10.0%, respectively). Urinary urgency was more frequent in the de-Leval patients (20.3% vs 2.8%). Conclusion: Our findings suggest that both tension-free vaginal tape obturator procedures are effective with few adverse effects. The Flam method provides shorter and decreased levels of postoperative thigh pain, as well as reduced long-term postoperative urinary urgency. [ABSTRACT FROM AUTHOR]

Cement extrusions on the femoral side after total hip replacement can occur in approximately 0.3% of cemented primary total hip replacements. Not recognised until a postoperative x-ray is performed, the willingness to dismiss and treat these extrusions conservatively is high.~Introduction~Background~We report on 3 patients presenting with sudden onset of thigh pain associated with an inability to weight-bear after a 2 to 15 month period of uneventful healthy recovery from cemented total hip replacement. On immediate postoperative x-rays occult cement extrusion in the posterolateral circumference of the femoral component tip were present. X-rays and CT scans showed no fracture signs. Scintigraphy revealed late increased uptake at the extrusion height. With the hypothesis of imminent femoral fatigue fracture, all patients underwent revision surgery. The defect sites were surgically exposed, thoroughly cleaned of cement, filled with iliac crest bone graft and stabilised with tension band plating.~Methods~Methods~This procedure resulted in fully recovered asymptomatic patients at 6 weeks and after a mean follow-up period of 48 months, as demonstrated by their pain level and tolerance of full weight bearing.~Results~Results~These cases lead us to adopt a low threshold for immediate revision when occult cement extrusion is recognised near the tip of a cemented stem on postoperative films, and to adopt a low threshold for surgical revision when, in the presence of cement extrusion, thigh pain is a complaint. We favour tension band plating and bone grafting over more complex implant revisions since a fast recovery was achieved in these patients.~Conclusions~Conclusions [ABSTRACT FROM AUTHOR]

We present the case of a ganglion cyst with 11 x 3 x 2 cm dimensions originating from the quadriceps femoris tendon. The patient presented with palpable mass and chronic pain in the anterolateral thigh region. The pain increased with walking. Ultrasonography and computed tomography revealed a cystic, well defined lesion in the vastus lateralis muscle. The patient was operated on and the cyst excised; it was seen to be a ganglion cyst. The patient is asymptomatic 6 months after surgery. This is a very rare localization for a giant synovial cyst, and preoperative diagnosis is a challenge for the surgeon. [ABSTRACT FROM AUTHOR]

A 9-year-old boy with thigh pain, high fever, hyperleukocytosis and positive blood cultures for Staphylococcus aureus had a left obturator internus phlegmon. Lack of evidence for hip infection or osteomyelitis in a child with thigh pain, high fever and hyperleukocytosis points to a possible infection of pelvic structures. Abscess or phlegmon of the obturator internus muscle is a very rare condition. The most frequent agent is Staphylococcus aureus. CT of the pelvis is the procedure of choice to show diffuse swelling of the muscle or collection of pus. Conservative treatment with adequate antibiotics is the treatment of choice.
