Peroneal Tendoscopy: Applied Anatomy and Operative Technique

Panagiotis D Symeonidis, Ioannis Spanos, Pim AD van Dijk, Niek C van Dijk
2022 Journal of Foot and Ankle Surgery Asia Pacific  
Pathologies related to the peroneal tendons are responsible for the largest percentage of retrofibular ankle pain, including a wide spectrum of relevant diagnoses. Diagnosing peroneal tendon pathologies, however, remains challenging as the accuracy of imaging studies including ultrasound (US) and magnetic resonance imaging (MRI) is still limited by constricting factors including operator dependence for US and the magic angle effect in MRI. On the contrary, advances in technology and our
more » ... e of the regional anatomy have rendered tendoscopy a viable option for patients with a high clinical suspicion for peroneal tendon pathology but a lack of positive findings on imaging. For both diagnosis and treatment of these patients, peroneal tendoscopy is recommended. The aim of the current study is to present a step-by-step, state of the art manner to perform a peroneal tendoscopy in a safe and reproducible manner. As indications of the method expand, an increasing number of surgeons with experience in foot and ankle arthroscopy have the chance to incorporate peroneal tendoscopy in their armamentarium. A detailed description of the operative technique with reference to recent data from anatomical and cadaveric studies is presented. Moreover, tips and pearls from the authors' accumulated experience are being highlighted. Finally, common pitfalls and limitations of the method are being discussed.

The cerebellar (para)flocculus: A review on its auditory function and a possible role in tinnitus

Lilian M. Mennink, J. Marc C. van Dijk, Pim van Dijk
2020 Hearing Research  
The cerebellum is historically considered to be involved in motor control and motor learning. However, it is also a site of multimodal sensory and sensory-motor integration, implicated in auditory processing. The flocculus and paraflocculus are small lobes of the cerebellum, in humans located in the cerebellopontine angle. The last two decades, both structures have been a subject of interest in hearing loss and tinnitus research. The current review summarizes insights on the auditory function
more » ... the (para)flocculus and its contribution to hearing loss and tinnitus. This leads to the hypothesis of a feedback loop between the paraflocculus and the auditory cortex. Disruption of this loop may be instrumental in both maintaining tinnitus and reducing tinnitus. Although the research mostly has been performed in animals, the implications in humans are also discussed. If the (para)flocculus indeed comprises an auditory function and is part of a tinnitus-mechanism, this would potentially open up new treatment options that involve direct intervention at the (para)flocculus.

A Lazy Brain? Embodied Embedded Cognition and Cognitive Neuroscience [chapter]

2008 Handbook of Cognitive Science  
We are well aware of the apparent tension between an EEC perspective of the brain and contemporary cognitive neuroscience research (see also van Dijk et al. in press ).  ...  In other words, instead of interpreting the brain's control system as the driver or pilot of the body, we see it as a traffic regulator (van Dijk et al., in press)---it is (merely, but importantly) assisting  ...

An auditory brainstem implant for treatment of unilateral tinnitus: protocol for an interventional pilot study

Minke J C van den Berge, Marc J M C van Dijk, Jan D M Metzemaekers, Bert Maat, Rolien H Free, Pim van Dijk
2019 BMJ Open  
IntroductionTinnitus may have a very severe impact on the quality of life. Unfortunately, for many patients, a satisfactory treatment modality is lacking. The auditory brainstem implant (ABI) was originally indicated for hearing restoration in patients with non-functional cochlear nerves, for example, in neurofibromatosis type II. In analogy to a cochlear implant (CI), it has been demonstrated that an ABI may reduce tinnitus as a beneficial side effect. For tinnitus treatment, an ABI may have
more » ... advantage over a CI, as cochlear implantation can harm inner ear structures due to its invasiveness, while an ABI is presumed to not damage anatomical structures. This is the first study to implant an ABI to investigate its effect on intractable tinnitus.Methods and analysisIn this pilot study, 10 adults having incapacitating unilateral intractable tinnitus and ipsilateral severe hearing loss will have an ABI implanted. The ABI is switched on 6 weeks after implantation, followed by several fitting sessions aimed at finding an optimal stimulation strategy. The primary outcome will be the change in Tinnitus Functioning Index. Secondary outcomes will be tinnitus burden and quality of life (using Tinnitus Handicap Inventory and Hospital Anxiety and Depression Scale questionnaires), tinnitus characteristics (using Visual Analogue Scale, a tinnitus analysis), safety, audiometric and vestibular function. The end point is set at 1 year after implantation. Follow-up will continue until 5 years after implantation.Ethics and disseminationThe protocol was reviewed and approved by the Institutional Review Board of the University Medical Centre Groningen, The Netherlands (METc 2015/479). The trial is registered at and will be updated if amendments are made. Results of this study will be disseminated in peer-reviewed journals and at scientific conferences.Trial registration numberNCT02630589.Trial statusInclusion of first patient in November 2017. Data collection is in progress. Trial is open for further inclusion. The trial ends at 5 years after inclusion of the last patient.

Profiling intermittent tinnitus: a retrospective review

Elouise A Koops, Fatima T Husain, Pim van Dijk
2019 International Journal of Audiology  
Objective: We conducted a retrospective review of medical records of tinnitus patients at a tertiary ENT clinic in Groningen, Netherlands. Our goal was to identify factors that differentiated the intermittent subgroup from the larger continuous group with chronic tinnitus. Design: Tinnitus-related factors such as hearing loss, emotional aspects, and demographics were used to advance our understanding of the subgroups. We analysed the data using descriptive statistics and binomial logistic

We examined 1575 medical intake records obtained at a tertiary ENT hospital. Results: Duration, total Tinnitus Handicap Inventory (THI), and THI Functional subscale scores differed significantly between the two groups. Increasing age and higher THI Emotional subscale scores were associated with an increased likelihood of intermittent tinnitus. Increases in duration, depressive scores and THI Functional and Catastrophic subscale scores, decreased the likelihood of intermittent tinnitus. Conclusions: Results from this study dissociate the factors affecting those with intermittent and those with continuous tinnitus and point to potentially different mechanisms underlying the two conditions.
