Background: Peripheral nerve stimulation (PNS) has been employed as a therapeutic modality for managing chronic pain across diverse etiologies and neural targets. Nevertheless, its application in treating chronic axial neck pain remains markedly underexplored. Accordingly, this study aimed to both review the existing literature and present a retrospective single-center case series of patients who underwent temporary PNS targeting the cervical medial branch nerves (CMBNs) for chronic axial neck pain. Methods: This investigation comprises a narrative literature review alongside a single-center, retrospective case series evaluating percutaneous, temporary PNS for the management of cervical spondylosis facet arthropathy in the absence of myelopathy or radiculopathy. The primary outcomes were pain reduction, as measured by the numeric rating scale, and improvements in functional disability, with assessments conducted at baseline and at 60 days post-intervention. Results: PNS represents a neuromodulatory, nondestructive intervention that targets the CMBN to alleviate chronic axial neck pain, in contrast to the destructive mechanisms inherent in cervical radiofrequency ablation (CRFA). Although PNS has been applied to other neural targets, its use in the cervical region is sparsely documented, with limited case studies available. Notably, this case series is the first to report pain and disability outcomes specifically associated with CMBN PNS. At the 60-day follow-up, 66% of subjects achieved the minimal clinically important difference (MCID) for pain reduction, while 77% met the MCID for disability reduction. Moreover, our analysis uniquely examined the impact of previous CRFA and a history of cervical spine surgery on treatment outcomes, revealing that patients with such interventions experienced more modest improvements compared to their surgery- and CRFA-naive counterparts. Conclusions: The current literature reveals a significant gap regarding the use of CMBN PNS, underscoring an unmet need in the treatment algorithm for chronic axial neck pain beyond conservative modalities. Our findings suggest that CMBN PNS may offer a promising adjunctive therapy for carefully selected patients with refractory chronic axial neck pain who have not improved after medications, physical therapy, or injections. Additionally, the comparative analysis of outcomes in patients with a history of CRFA or cervical surgery underscores potential advantages of PNS prior to destructive therapies. Future research, ideally in the form of prospective studies with larger cohorts and extended follow-up durations, is warranted to further evaluate long-term outcomes and refine the place of PNS in the treatment algorithm.

Background/Objectives: Patient-reported outcome measures (PROMs) are widely used tools in orthopedic surgery for evaluating clinical outcomes, guiding research, and supporting value-based care. However, the optimal timing for collecting baseline PROMs, whether in clinic prior to surgery or on the day of surgery, remains uncertain. This study investigated whether the clinical setting (preoperative clinic vs. day of surgery) affects baseline PROMs in patients undergoing anterior cervical discectomy and fusion (ACDF). Methods: Patients undergoing elective, primary ACDF at a single institution between August 2019 and June 2021 were prospectively enrolled. Inclusion criteria included age over 18, English literacy, and eligibility for primary ACDF. Participants completed PROMIS domains, Neck Disability Index (NDI), Modified Japanese Orthopaedic Association (mJOA) score, and Visual Analog Scale (VAS) at two time points: during the preoperative clinic visit and again in the perioperative area on the day of surgery. A subgroup analysis was performed for patients with anxiety, defined as a PROMIS anxiety score ≥ 59.4. Results: A total of 63 patients were enrolled, with 48 completing both sets of surveys. The average time between the two assessments was 7.9 days (95% CI: 6.4–9.3). After Bonferroni correction (α = 0.005), no significant differences were observed in any PROMs across the two time points, including PROMIS physical function (p = 0.398), pain interference (p = 0.682), fatigue (p = 0.019), social satisfaction (p = 0.331), anxiety (p = 0.047), depression (p = 0.042), NDI (p = 0.072), mJOA (p = 0.566), VAS neck pain (p = 0.054), or VAS overall pain (p = 0.335). Subgroup analysis of anxious patients similarly revealed no statistically significant changes between settings. Conclusions: PROM scores were not meaningfully different between the preoperative clinic and the day of surgery in patients undergoing ACDF. These results are most applicable when baseline PROMs are collected within about one week of ACDF. These findings support flexibility in workflow design for PROM collection, as the timing and setting do not significantly impact baseline responses. Full article

Background: Cervicogenic headache (CGH) is a prevalent secondary headache disorder associated with upper cervical spine dysfunction, often involving nociceptive convergence at the trigeminocervical complex. While manual therapy and exercise have demonstrated benefit, autonomic dysregulation may contribute to persistent symptoms. This case report explores the integration of external vagus nerve stimulation (eVNS) into a multimodal physical therapy approach targeting both mechanical and neurophysiological contributors to CGH. Case Description: A 63-year-old female presented with chronic CGH characterized by right-sided suboccipital and supraorbital pain, impaired sleep, and postural dysfunction. Examination revealed a right rotational atlas positional fault, restricted left atlantoaxial (AA) mobility, suboccipital hypertonicity, and reduced deep neck flexor endurance. Initial treatment emphasized manual therapy to restore AA mobility and atlas symmetry, combined with postural correction and neuromuscular training. Intervention: After initial symptom improvement plateaued, eVNS targeting the auricular branch of the vagus nerve was introduced to modulate autonomic tone. The patient used a handheld eVNS device nightly over three weeks. Outcomes: Substantial improvements were observed in the Neck Disability Index (↓77%), Headache Disability Inventory (↓72%), and pain scores (↓100%). Cervical mobility, atlas symmetry, and deep neck flexor endurance improved markedly. The patient reported reduced anxiety, improved sleep, and sustained headache relief at one-month follow-up. Conclusions: This case highlights the potential synergistic benefits of integrating eVNS within a physiotherapy-led CGH management plan. Further research is warranted to explore its role in targeting autonomic imbalance and enhancing conservative treatment outcomes. Full article

Background/Objectives: Photoimmunotherapy for head and neck cancer (HN-PIT) is an emerging treatment for unresectable locally advanced or recurrent head and neck cancer. However, real-world data (RWD) are limited. This study examined the safety and effectiveness of HN-PIT. Methods: This multicenter, retrospective cohort study included 40 patients with unresectable locally advanced or recurrent head and neck cancers who underwent HN-PIT from January 2021 to August 2024. The primary endpoint was time to treatment failure (TTF). Secondary endpoints included the objective response rate (ORR), overall survival (OS), progression-free survival (PFS), and adverse events (AEs). Results: The median TTF and 1-year treatment failure rate were 6.0 months and 23.2%, respectively. Moreover, the ORR, disease control rate, median OS, and median PFS were 75.0% (95% confidence interval [CI]: 60.0–86.0%), 95.0% (95% CI: 83.5–99.0%), 26.9 months, and 6.2 months, respectively. The incidence of grade ≥3 AEs was 17.5% (95% CI: 7.1–29.1%). Pain was the most common AE, occurring in 37 patients (92.5%), with grade III pain reported in 5 (12.5%). Mucositis occurred in 32 patients (80.0%), with grade III mucositis reported in 3 (7.5%). Hemorrhages occurred in 31 patients (77.5%), with no grade ≥III hemorrhages reported. Two patients experienced sepsis (5.0%; grades IV and V). Seventeen patients (42.5%) had laryngeal edema, with grade IV edema reported in four (10.0%). Conclusions: Our RWD shows that HN-PIT is effective with an acceptable safety profile. TTF may serve as an endpoint reflecting this treatment’s characteristics. This study provides important basic data for the development of future treatment strategies. Full article

Background: Orofacial pain (OFP) and headache are common and disabling conditions in people with head and neck cancer (HNC), although their clinical characteristics and underlying pain mechanisms remain poorly studied, leading to worse diagnosis and, thus, management. Therefore, this review aims to synthesize the literature regarding clinical features, pain descriptors, mechanisms, and assessment tools of OFP and/or headache in adults with HNC. Methods: A scoping review was conducted following the Arksey and O’Malley framework and reported using PRISMA-ScR guidelines. We searched PubMed, Embase, Scopus, and Web of Science. Quantitative and qualitative original studies were included. Data were charted and summarized using narrative synthesis. Results: Of 3647 records initially retrieved, 32 studies met the inclusion criteria. Most studies were observational and heterogeneous in design, population, and pain assessment methods. OFP was highly prevalent, with neuropathic descriptors (e.g., burning, electric shocks, tingling) reported in 13.1% to 64.5% of patients, although heterogeneity in study design and tools used to assess this potential pain mechanism was high. Pain was frequently localized at the tumor site, although pain in other regions beyond the head and neck was also reported. Pain intensity was generally moderate, although varied across studies. OFP and headache in HNC patients were often neuropathic in nature and contributed significantly to disability and reduced quality of life. Most articles lacked mechanistic classifications of pain, although some suggested that central sensitization may be involved in some patients. Conclusions: Orofacial pain and headache are prevalent, under-characterized symptoms in HNC patients. There is an urgent need for standardized assessments using validated tools to improve phenotyping and inform targeted treatment strategies. Full article

Background and Clinical Significance: Cocaine-induced vasculitis (CIV), especially when associated with PR3-ANCA positivity, can be very similar both clinically and serologically to idiopathic granulomatosis with polyangiitis (GPA). The distinction between these entities is crucial due to the different etiologies, treatment strategies, and prognoses. We present a unique case of CIV that manifested exclusively in a previously dissected neck area—an example of the locus minoris resistance phenomenon—and was initially misinterpreted as skin melanoma recurrence. Case presentation: A 59-year-old man with a history of skin melanoma (pT4b, left pectoral region) and a previous modified radical neck dissection presented in 2024 with new onset of painful subcutaneous nodules and ulcerative lesions at the surgical site. The imaging procedures (CT and PET-CT) raised the suspicion of locoregional malignant recurrence. However, histology revealed necrotizing granulomatous inflammation without tumor cells. Extensive infectious and autoimmune investigations ruled out alternative causes. Subsequently, the patient developed a perforation of the nasal septum and ulcers on the oral mucosa. PR3-ANCA was strongly positive (up to 49 U/mL). Urine toxicology revealed intranasal cocaine use. A diagnosis of cocaine-induced PR3-ANCA vasculitis was made. After immunosuppressive therapy (high-dose glucocorticoids and methotrexate) and substance withdrawal counseling, the patient showed significant clinical improvement. Conclusions: This case highlights the importance of including CIV in the differential diagnosis of granulomatous or ulcerative lesions, especially when they are localized to previous surgical sites. The presentation illustrates the concept of locus minoris resistentiae and highlights the role of toxicological testing in atypical ANCA-positive disease. Full article

Chronic musculoskeletal pain negatively affects patients’ quality of life, and pain perceptions may significantly influence rehabilitation outcomes. This study investigated the relationships among pain intensity, pain perceptions, and kinesiophobia in individuals with chronic musculoskeletal pain. No previous studies have examined these variables in combination. A cross-sectional observational study was conducted with 37 participants with non-specific chronic musculoskeletal pain for at least 6 months, affecting the neck (n = 8), lower back (n = 18), upper limbs (n = 5), lower limbs (n = 5), or shoulder (n = 1). The following validated tools were used: (a) Pain Beliefs and Perceptions Inventory (PBPI), (b) the Tampa Scale for Kinesiophobia (TSK), and (c) the Short-Form McGill Pain Questionnaire (SF-MPQ). Spearman r correlation analyses were performed. Total kinesiophobia scores were positively correlated with (a) total pain intensity (McGill score) (r = 0.37, p = 0.022), (b) present pain intensity (PPI) (r = 0.52, p = 0.001), (c) pain duration (r = 0.51, p = 0.001), (d) the “mystery” factor of pain perception (r = 0.41, p = 0.013), and (e) the Visual Analogue Scale (VAS) (r = 0.42, p = 0.009). The total pain perception scores were positively associated with the “fear of injury” factor of kinesiophobia (r = 0.36, p = 0.028). The McGill pain scores were strongly correlated with both PPI (r = 0.63, p = 0.001) and VAS (r = 0.51, p = 0.001). There is a significant relationship between pain perception and kinesiophobia levels in patients with chronic musculoskeletal pain. Limitations of the study include a small and heterogeneous sample regarding pain localization. Further research is required using larger, more homogeneous populations to confirm the present findings.

Background/Objectives: Neck pain caused by myofascial pain syndrome (MPS) is a highly prevalent musculoskeletal condition. Repetitive peripheral magnetic stimulation (rPMS) is a promising treatment option; however, its therapeutic effect and optimal treatment frequency remain unclear. This study aimed to investigate the therapeutic effect and duration of effect of rPMS in patients with MPS of the neck. Methods: In this randomized, sham-controlled, crossover trial, 27 patients with neck MPS and baseline visual analog scale (VAS) scores ≥ 40 were enrolled. The mean age was 43.8 ± 9.1 years, and 63% were female. Participants were randomly assigned to receive either an initial rPMS treatment (a 10 min session delivering 3900 pulses at 5–10 Hz) or sham stimulation. After 7 days, groups crossed over. Pain intensity (VAS), disability (Neck Disability Index; NDI), and analgesic use were recorded daily for seven consecutive days. A linear mixed-effects model was used for analysis. Results: At baseline, the VAS and NDI scores were 61.8 ± 10.5 and 26.0 ± 6.3, respectively. rPMS produced a significantly greater reduction in both VAS and NDI scores, with the greatest differences observed on Day 4: the differences were −24.1 points in VAS and −8.5 points in NDI compared to the sham group. There was no significant difference in analgesic use between the two groups. Conclusions: A single rPMS session provides short-term improvement in pain and disability in neck MPS. Based on the observed therapeutic window, more frequent sessions (e.g., twice weekly) may provide sustained benefit and should be explored in future studies. Full article

Background/Objectives: A randomized controlled trial (RCT) was designed to test the emerging role of respiratory mechanics as part of physiotherapy in patients with non-specific chronic neck pain (NSCNP). Methods: Ninety patients with NSCNP and symptom duration >3 months were randomly allocated to three intervention groups of equal size, receiving either cervical spine (according to the Mulligan Concept) and diaphragm manual therapy plus breathing reeducation exercises (experimental group—EG1), cervical spine manual therapy plus sham diaphragmatic manual techniques (EG2), or conventional physiotherapy (control group—CG). The treatment period lasted one month (10 sessions) for all groups. The effect on the cervical spine range of motion (CS-ROM) and on the craniovertebral angle (CVA) was examined. Outcomes were collected before treatment (0/12), after treatment (1/12), and three months after the end of treatment (4/12). The main analysis comprised a two-way mixed ANOVA with a repeated measures factor (time) and a between-groups factor (group). Post hoc tests assessed the source of significant interactions detected. The significance level was set at p = 0.05. Results: No significant between-group baseline differences were identified. Increases in CS-ROM and in CVA were registered mainly post-treatment, with improvements maintained at follow-up for CS-ROM. EG1 significantly improved over CG in all movement directions except for flexion and over EG2 for extension only, at 1/12 and 4/12. All groups improved by the same amount for CVA. Conclusions: EG1, which included diaphragm manual therapy and breathing re-education exercises, registered the largest overall improvement over CG (except for flexion and CVA), and for extension over EG2. The interaction between respiratory mechanics and neck mobility may provide new therapeutic and assessment insights of patients with NSCNP. Full article

Background: Traumatic fractures of the cervical spine pose significant challenges in management, particularly in young patients, where preserving mobility is crucial. Patient Characteristics: A 30-year-old woman presented with a C3 lateral mass and pedicle fracture following a motor vehicle collision. Initial conservative management with a rigid cervical collar for three months failed to reduce the diastasis, and the debilitating neck pain worsened. Preoperative imaging confirmed fracture instability without spinal cord compression. Intervention and Outcome: Preoperative screw trajectory planning was conducted with the My Spine MC system (Medacta), and fine-tuning was achieved on a 3D-printed model of the vertebra. A posterior midline approach was employed to expose the C3 vertebra, and a Herbert screw was inserted under fluoroscopic guidance. Imaging at three months demonstrated significant fracture reduction and early bone fusion. The patient achieved substantial improvement in functional mobility without complications. Conclusion: Herbert screw fixation holds potential as a less-invasive alternative to conventional posterior stabilization for selected cervical fractures. This technical note provides the reader with the required information to support surgical planning and execution. Full article

Background: Surgical neck nonunions of the proximal humerus present a complex clinical challenge, especially in elderly patients with pre-existing glenohumeral arthritis. Reverse total shoulder arthroplasty (RTSA) offers a reliable treatment option in these cases; however, resection of the tuberosities may compromise joint stability, increase the risk of postoperative dislocation and compromise postoperative function. This article describes a reproducible RTSA technique that preserves and repairs the greater and lesser tuberosities, aiming to enhance construct stability and optimize outcomes. Methods: We present a 74-year-old female with underlying glenohumeral arthritis who underwent RTSA for a symptomatic surgical neck nonunion via an extended deltopectoral approach. The nonunion is first mobilized, and tuberosity osteotomies are performed. After implant placement, the tuberosities are secured to the implant, to each other, and to the humeral shaft. A cerclage suture is also passed circumferentially to reinforce the repair and prevent posterior gapping. Results: The patient regained her pre-injury level of function by her last follow-up. She had pain-free, active forward elevation to 110 degrees and radiographic evidence of maintained tuberosity reduction and healing. There was no evidence of instability. Conclusions: In conclusion, incorporating tuberosity preservation and repair into RTSA for proximal humerus nonunion may reduce dislocation risk and improve functional recovery in elderly, low-demand patients.

Chronic neck pain is a multifactorial condition involving physical, psychological, and neurological dimensions. This case report describes the clinical course of a 25-year-old female with chronic neck pain and recurrent headaches who underwent a 6-week integrative intervention consisting of manual therapy and pain neuroscience-based sensorimotor retraining, administered three times per week. Outcome measures included the Headache Impact Test-6 (HIT-6), Neck Pain and Disability Scale (NPDS), Pain Catastrophizing Scale (PCS), Fear-Avoidance Beliefs Questionnaire (FABQ), pressure pain threshold (PPT), cervical range of motion (CROM), and functional near-infrared spectroscopy (fNIRS) to assess brain activity. Following the intervention, the patient demonstrated marked reductions in pain and psychological distress: HIT-6 decreased from 63 to 24 (61.9%), NPDS from 31 to 4 (87.1%), FABQ from 24 to 0 (100%), and PCS from 19 to 2 (89.5%). Improvements in PPT and CROM were also observed. fNIRS revealed decreased dorsolateral prefrontal cortex (DLPFC) activation during pain stimulation and movement tasks, suggesting a possible reduction in central sensitization burden. These findings illustrate that an integrative approach targeting biopsychosocial pain mechanisms may be beneficial in managing chronic neck pain, improving function, and modulating cortical responses. This report provides preliminary evidence in support of the clinical relevance of combining manual therapy with neurocognitive retraining in similar patients. Full article

Tinea incognito is an incorrectly diagnosed form of fungal infection due to a changed clinical picture as a result of systemic or topical corticosteroids or even local immunomodulators. This type of skin lesion is most often located on the trunk but can affect any part of the body. We present a case report of 76-year-old woman with a history of systemic lupus erythematosus who was admitted to hospital because of extensive, painful, and burning erythematous and papular lesions in an annular pattern, covered with a thick, yellow crust, located on the scalp and neck. The skin lesions were accompanied by extensive hair loss. The patient had previously undergone intensified treatment of the underlying disease due to the exacerbation of skin lesions of a subacute cutaneous lupus erythematosus type. A suspicion of tinea incognito was raised, and direct mycological examination and culture confirmed the presence of dermatophytes (Microsporum spp.). Tinea incognito can be difficult to diagnose because the clinical picture is relatively nonspecific and can mimic other dermatoses, such as subacute lupus erythematosus. Therefore, in doubtful cases it is necessary to perform a direct test and culture for fungal infection, especially before initiating treatment with glucocorticosteroids and other immunosuppressive agents.

Background/Objectives: Neck pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, affecting the cervical region. It represents one of the leading causes of disability, with a prevalence of 30%. Transcranial direct current stimulation (tDCS) is a non-invasive electrotherapy technique that enables direct modulation of cortical excitability. It involves the application of a low-intensity electrical current to the scalp, targeting the central nervous system. The aim of this study was to analyze the effects of tDCS on functionality, pain, mobility, and pressure pain threshold in patients with chronic nonspecific neck pain. Methods: Thirty participants (18–60 years) were selected to receive ten treatment sessions over a four-week period using tDCS (CG = 15) or transcutaneous electrical nerve stimulation (TENS) (CG = 15), with the following various related variables evaluated: functionality (Neck Disability Index), pain intensity (NPRS), cervical range of motion (ROM), and pressure pain threshold (PPT). Assessments were conducted at baseline, post-treatment, one month, and three months after the intervention. Results: The within-group analysis revealed statistically significant improvements for both groups at post-treatment, one-month follow-up, and three-month follow-up. Conclusions: The comparison between groups shows favorable changes in the tDCS group for PPT measurements. Full article

Objectives: New smartphone-based methods for measuring cervical spine range of motion (CS-ROM) and posture are emerging. The purpose of this study was to assess the reliability and validity of three such methods in patients with non-specific chronic neck pain (NSCNP). Methods: The within-day test–retest reliability of CS-ROM and forward head posture (craniovertebral angle-CVA) was examined in 45 patients with NSCNP. CS-ROM was simultaneously measured with an accelerometer sensor (KFORCE Sens^®) and a mobile phone device (iHandy and Compass apps), testing the accuracy of each and the parallel-forms reliability between the two methods. For construct validity, correlations of CS-ROM with demographics, lifestyle, and other cervical and thoracic spine biomechanically based measures were examined in 90 patients with NSCNP. Male–female differences were also explored. Results: Both methods were reliable, with measurements concurring between the two devices in all six movement directions (intraclass correlation coefficient/ICC = 0.90–0.99, standard error of the measurement/SEM = 0.54–3.09°). Male–female differences were only noted for two CS-ROM measures and CVA. Significant associations were documented: (a) between the six CS-ROM measures (R = 0.22–0.54, p < 0.05), (b) participants’ age with five out of six CS-ROM measures (R = 0.23–0.40, p < 0.05) and CVA (R = 0.21, p < 0.05), (c) CVA with two out of six CS-ROM measures (extension R = 0.29, p = 0.005 and left-side flexion R = 0.21, p < 0.05), body mass (R = −0.39, p < 0.001), body mass index (R = −0.52, p < 0.001), and chest wall expansion (R = 0.24–0.29, p < 0.05). Significantly lower forward head posture was noted in subjects with a high level of physical activity relative to those with a low level of physical activity. Conclusions: The reliability of both CS-ROM methods was excellent. Reductions in CS-ROM and increases in CVA were age-dependent in NSCNP. The significant relationship identified between CVA and CWE possibly signifies interconnections between NSCNP and the biomechanical aspect of dysfunctional breathing. Full article
