Background: Peripheral nerve lesions are associated with debilitating long-term consequences. Albeit being essential for evidence-based clinical decision making, epidemiological and etiological data are scarce. We therefore aimed to comprehensively analyze epidemiological and etiological factors of peripheral nerve lesions in one of the largest cohorts. Methods: We screened a total of 110,667 patients treated at our level I trauma center between January 2012 and July 2020 for nerve lesions. Subsequently, demographics, etiologies, concomitant injuries, and lesion characteristics were analyzed. Results: A total of 5026 patients, predominantly young males suffering from non-work-related nerve injuries, were treated. Proximal levels of injury were more likely to be accompanied by fractures, whereas more distal injuries with concomitant vessel or tendon injury. Main causes were 54.6% lacerations. Acute traumatic nerve injury was treated within 24 h in 55.9% of cases. Conclusions: Given the young age of affected patients, early diagnosis and treatment in specialized centers may facilitate their early return to work and improve long-term functional outcomes. The data show the importance of a special attention on nerve injuries, which may be masked by large accompanying injuries. New findings on lesion characteristics of selected subgroups and accompanying circumstances can support a change in treatment strategies.

Burn injuries are a major healthcare challenge worldwide, with up to 50% of all minor burns located on the head and neck. With this study, we sought to describe the effect of facial burns (FB) on health-related quality of life through a prospective and matched cohort study design. Patients completed the 36 Item Short Form (SF-36) and the Hospital Anxiety and Depression Scale (HADS). Results were analyzed based on the distribution of datasets. In total, 55 patients with FB and 55 age-and sex-matched candidates were recruited. The most common mechanism of thermal injury was burns from flames. The FB group scored lower in physical and psychological dimensions than the control group, both acutely and one year after injury. An analysis of each domain showed that subjects in the FB group trended toward improvements in their score after one-year post-burn in physical functioning (acute: 71.0 ± 29.2; one-year: 83.7 ± 23.9; p = 0.02) and bodily pain (acute: 58.5 ± 30.3; one-year: 77.9 ± 30.5; p = 0.01) domains. Additionally, the FB group had significanlyt higher scores for anxiety (FB: 4.8 ± 3.2; control: 2.5 ± 2.8; p = <0.002) and depression (FB: 3.9 ± 3.5; control: 2.1 ± 2.7; p = 0.01) compared to the control. In conclusion, facial burns are associated with physical and psychosocial deficits, as well as elevated levels of psychological distress.

Background: Severe burn injuries often lead to lasting physical and psychological consequences. Post-traumatic stress disorder (PTSD) is common among burn survivors and may be influenced by persistent somatic complaints. This study examined whether PTSD is associated with a higher burden of physical symptoms during and after inpatient rehabilitation. Methods: We conducted a subgroup analysis of a multicenter prospective cohort study involving 103 adult burn patients in inpatient rehabilitation. Based on Impact of Event Scale—Revised (IES-R) scores and clinical evaluation, patients were grouped as PTSD (n = 43) or No PTSD (n = 60). Physical symptoms assessed included skin dryness (xerosis), temperature sensitivity (cold/heat), numbness, skin tightness, and increased sweating. Results: Patients with PTSD reported significantly more physical symptoms at follow-up than those without PTSD: xerosis (74% vs. 50%, p = 0.03), cold sensitivity (61% vs. 35%, p = 0.02), heat sensitivity (63% vs. 39%, p = 0.03), numbness (63% vs. 33%, p = 0.006), skin tightness (82% vs. 52%, p = 0.004), and sweating (45% vs. 19%, p = 0.01). PTSD patients also had more severe burns, reflected in higher full-thickness TBSA (2% vs. 0%, p = 0.03) and elevated ABSI scores (median 6 vs. 5, p = 0.04). Conclusion: PTSD is associated with a higher and more persistent burden of physical skin symptoms after severe burns. These findings underscore the importance of early PTSD screening and integrated psychological-somatic rehabilitation to improve long-term recovery and quality of life.

(1) Background: Peripheral nerve injuries are severe injuries with potentially devastating impairment of extremity function. Correct and early diagnosis as well as regular regeneration observation is of utmost importance for individualized reconstruction and the best possible results. Currently, diagnoses and follow-up examinations are based on clinical examinations supported with electroneurography, which often causes delays in treatment and can result in impaired healing. However, there is currently no diagnostic device that can reliably correlate the anatomic–pathological parameters with the functional–pathological changes initially and during therapy. With new technologies such as MR neurography (MRN), precise visualization of potential nerve damage and visualization of the reinnervation processes is assumed to accelerate clinical decision making and accompaniment of individualized treatment. (2) Methods/Design: This prospective clinical study will examine 60 patients after peripheral nerve lesion aged 18–65 years from trauma timepoint onward. Patients should be observed over a period of 18–24 months with regular clinical examinations, electroneurography, and ultrasound to compare the potential of MRN to current gold-standard diagnostic tools. Furthermore, 20 patients with the same inclusion criteria stated above, with an internal fixation and osteosyntheses of humerus fractures, will be examined to determine the visibility of peripheral nerve structures in close proximity to metal. (3) Discussion: Peripheral nerve injuries are often accompanied with severe, expensive, and long-lasting impairment of extremity function. An early and precise diagnosis of the nerve lesion, as well as the healing course, is crucial to indicate the right therapy as soon as possible to save valuable time for nerve regeneration. Here, new technologies such as MRN aim to visualize nerve injuries on fascicular level, providing not only early diagnosis and therapy decisions, but also providing a precise tool for monitoring of reinnervation processes. As severe injuries of a nerve are often accompanied with bone fractures and internal fixation, we also aim to evaluate the visualization feasibility of nerves in close proximity to metal, and ultimately improve the outcome and extremity function of patients after a peripheral nerve injury.

Burn injuries have a lasting impact on physical and psychological health. This study evaluated outcomes for two burn-specific rehabilitation programs based on the International Classification of Functioning, Disability, and Health (ICF) model. In a prospective multicenter trial, 103 patients with work-related burn injuries underwent multidisciplinary rehabilitation in either a newly established ICF-based program (Center A) or a well-established program (Center B). A comprehensive outcome assessment was performed at the beginning (T1) and the end of inpatient rehabilitation (T2), and at three (T3) and 12 months (T4) after discharge to evaluate the effectiveness of the two rehabilitation programs. The study included an analysis of longitudinal changes within each center to assess patient outcomes over time and a comparison between the two centers at each time point to evaluate potential differences in rehabilitation effectiveness. Primary outcomes were the Physical Component Score (PCS) and Mental Component Score (MCS) of the 36-Item Short Form Survey (SF-36), with secondary outcomes including grip strength, active range of motion (AROM), and burn scar assessment among others. Results showed significant improvements in physical health (SF-36 PCS) from T1 to T4 (p < 0.001), while mental health (SF-36 MCS) showed no significant change (p = 0.20). Grip strength and AROM improved significantly over time in both centers. Non-inferiority between centers was confirmed for all outcomes except MCS at T2 and T3. This study highlights the positive impact of ICF-based rehabilitation on physical recovery, with ongoing mental health needs underscoring the importance of long-term psychological support for burn survivors.

Background: Nerve entrapment has been hypothesized to contribute to the multicausal etiology of axonopathy in sensorimotor diabetic neuropathy. Targeted surgical decompression reduces external strain on the affected nerve and, therefore, may alleviate symptoms, including pain and sensory dysfunction. However, its therapeutic value in this cohort remains unclear. Aim: Quantifying the treatment effect of targeted lower extremity nerve decompression in patients with preexisting painful sensorimotor diabetic neuropathy and nerve entrapment on pain intensity, sensory function, motor function, and neural signal conduction. Study design: This prospective, controlled trial studies 40 patients suffering from bilateral therapy-refractory, painful (n = 20, visual analogue scale, VAS ≥ 5) or painless (n = 20, VAS = 0) sensorimotor diabetic neuropathy with clinical and/or radiologic signs of focal lower extremity nerve compression who underwent unilateral surgical nerve decompression of the common peroneal and the tibial nerve. Tissue biopsies will be analyzed to explore perineural tissue remodeling in correlation with intraoperatively measured nerve compression pressure. Effect size on symptoms including pain intensity, light touch threshold, static and moving two-point discrimination, target muscle force, and nerve conduction velocity will be quantified 3, 6, and 12 months postoperatively, and compared (1) to the preoperative values and (2) to the contralateral lower extremity that continues non-operative management. Clinical significance: Targeted surgical release may alleviate mechanical strain on entrapped lower extremity nerves and thereby potentially improve pain and sensory dysfunction in a subset of patients suffering from diabetic neuropathy. This trial aims to shed light on these patients that potentially benefit from screening for lower extremity nerve entrapment, as typical symptoms of entrapment might be erroneously attributed to neuropathy only, thereby preventing adequate treatment.
