- Unusual Relationship between the Piriform Muscle and Sciatic, Inferior Gluteal and Posterior Femoral Cutaneous Nerves(2014) JACOMO, A. L.; MARTINEZ, C. A. R.; SALEH, S. O.; ANDRADE, M.; AKAMATSU, F. E.Piriformis muscle syndrome has been increasingly recognized as a cause of leg pain. Overuse, strain, or anatomical variations of the relationship between the nerve and the piriformis muscle are thought to be the underlying causes of the entrapment of the sciatic nerve. We report a variation not previously described which was found during a routine dissection. During routine dissection of the left gluteal region of an adult male cadaver we observed a high division of the sciatic nerve and the presence of an accessory piriformis muscle. The sciatic nerve divided beneath the piriformis muscle and the common fibular nerve passed over the accessory piriformis muscle, whereas the tibial nerve reflected anteriorly to pass between the accessory piriformis and the superior gemellus muscle. Additionally, both nerves communicated with a side branch under the inferior border of the accessory piriformis muscle and the inferior gluteal nerve originated from the fibular nerve. Anatomical variations in the relationship between the piriformis muscle and the sciatic nerve may be present in up to 17% of the population. Six different variations have been described and none of them is similar to our description. Though complete understanding of the physiopathology of the piriformis muscle syndrome remains to be elucidated, knowledge of the possible anatomical variations may be useful for its adequate diagnosis and treatment.
- Anatomical Bases of the Temporal Muscle Trigger Points(2024) GARRIDO, Luis Carlos Fernandez; SIMONETTI, Giulianna; SALEH, Samir Omar; HOJAIJ, Flavio; ANDRADE, Mauro; JACOMO, Alfredo Luiz; AKAMATSU, Flavia EmiBackground and Purpose. Myofascial pain syndrome (MPS) is a chronic or acute form of musculoskeletal pain that affects nearly three-quarters of the world's population. It is characterized by muscle pain and stiffness, with palpable nodules and hyperirritability areas called myofascial trigger points (MTPs). The temporal muscle is frequently involved in MPS, and four MTPs in the temporal muscle have been described in the literature, but no anatomical description of the MTPs has been reported. The present study described the entry points of deep temporal nerves in the temporal muscle belly and related these points to the MTPs described in the literature. Method. Temporal muscles of 14 adult cadavers were studied. The muscle bellies were divided into six areas, three superior (1.2 and 3) and three inferior areas (4, 5, and 6) lower, according to a Cartesian plane to analyze and describe the entry points of the branches of the deep temporal nerves into the muscle. The branching distribution was analyzed using Poisson log-linear tests with Bonferroni post hoc tests for comparison between groups (sextants) (p<0.05). Results. Deep temporal nerve entry points were found in the temporal muscle in all areas. Most of the branches were observed in areas 2 and 5, which coincide with the muscle fibers responsible for mandible elevation and related to the previously described MTPs. Fewer branches were found in areas 1 and 6, where contraction produces mandible retraction. Conclusion. There is an anatomical correlation between the branching pattern of the deep temporal nerve and temporal muscle trigger points. Adequate knowledge of the innervation of the temporal muscle may help elucidate the pathophysiology of myofascial syndromes and provide a rational basis for interventional or conservative approaches and help surgeons avoid iatrogenic lesions to the deep temporal nerve lesion.
- A Rare Pattern of Brachial Artery Variation - Case Report(2014) JACOMO, A. L.; MARTINEZ, C. A. R.; SALEH, S. O.; ANDRADE, M.; AKAMATSU, F. E.Unlike the venous system, variations in arterial anatomy are less frequent and most of them affect visceral arteries. In limbs, variations of the brachial artery are the most reported and at least six different patterns have been described so far. The commonest is the superficial brachial artery which lies superficially to the median nerve. Much less prevalent are the high origin of the radial artery (brachioradial artery) or the existence of a doubled brachial artery (accessory brachial artery). We present a previously undescribed pattern of brachial artery variation. During dissection of the right upper limb of a 60 year-old male embalmed cadaver, we found the bifurcation of the brachial artery in the proximal portion of the middle third of the arm. Its medial branch reaches the medial aspect of the arm, posterior to the median nerve. Afterwards, this medial branch redirects laterally and crosses again the median nerve, this time lying anterior to the nerve until it reaches the lateral aspect of the arm. At the elbow level, the medial branch originates the radial artery. The lateral branch of the brachial artery remains lateral to the median nerve and continues as ulnar artery and originates the interosseus artery.
