Recurrent artery of Heubner (RAH) is the largest and most constant perforating branch of anterior cerebral artery. It supplies blood to the medial portion of the orbitofrontal cortex, the anterior portion of the caudate nucleus, the anterior third of the putamen, the external segment of the globus pallidus, and the anterior crus of the internal capsule The anatomical variation of RAH is related to its traject, number, presence, or absence, and the diverse origin from ACA is of considerable clinical impact mainly from the point of view of the surgical procedures involving the anterior portion of the circle of Willis or the topographically related structures. The present study aimed to demonstrate vascular anatomy of this RAH and its variation. The study included 60 human cadaveric brains fixed in the formalin and examined under operating microscope. 22 freshly harvested human cadaveric brains, injected with a polymer (Technovit 7143), a partial coroded and also we have consulted 30 digital subtraction angiograms. We have evaluated the origin, traject and caliber of recurrent artery of Heubner, our results were compared with other anatomical studies published. The most obvious finding was the great variability of its origin but in 91% of the cases it was in the range of 2mm around anterior communicating artery, that could be harmed during aneurismal clipping. The RAH is commonly arising from ACA-ACoA junction. This portion of the circle of Willis is the place of many anatomical variations and malformations. The vessel can be absent, single, or multiple, and its diameter is highly variable. The awareness of these distinct anatomical and morphometric variations of the RAH is essential in planning the neurosurgical procedures in the anterior part of the circle of Willis to avoid the unexpected neurological complications.

The simultaneous occurrence of two rare conditions in a single patient is uncommon. We report the case of a patient with rectal actinomycosis covering an anorectal melanoma (both infrequent conditions), the last one being later recognized, only after surgical excision. We underline here the role of thinking "outside the box" when an unusual situation is experienced.

The aim of the present study conducted on the lumbar spine was to confirm that the pronounced decrease in resistance in the system is a phenomenon that can be eminently affected by the adaptive changes that occur at the level of the intervertebral disc at axial mechanical stresses. The biomechanical trial was carried out on 11 lumbar segments L1-L5, gathered from adult human cadavers. The dissection considered the complete keeping of all bone, disc, articulated and ligamentous components in their anatomical position. All 11 samples were frozen 24 h prior to the performance of the biomechanical measurement. The specimens were placed in the testing device, their placement being conditioned by the estimated dimensional values. Thus, to calculate the load and axial resistance, the models were placed vertically, central between the test machine ferries. The testing was carried out by applying variable forces and displacement supervision. The displacement interval was represented by a segment of 0-10 mm with surveillance every 2 mm. Mobility in the sagittal plane (flexion earlier in our case) was much higher than that in the frontal plane, obviously limiting mobility via the intervertebral disc and articular complex through the presence of arches. Statistical analysis demonstrated the lack of any correlation values between the two types of movements (R 2 =0.005507), underlining the absence of any prediction elements. A noteworthy aspect is that the correlations appeared low, statistically insignificant, even within the same movement in the sagittal plane between the two levels, L1-L3 and L3-L5 (R 2 =0.610427), which may lead to the possibility of the emergence of significant differences in mobility between respective levels. The behavior type of the monitored specimens and the results obtained allowed the mapping of objective parallelism between the values obtained and the behavior in vivo of the lumbar vertebral segment.

Introduction. Fractures of the distal radius epiphysis are the most common fractures of the upper limb, present both in the general population active following major trauma and in the elderly population in minimal trauma due to osteoporosis. Among the adjuvant therapies for orthopedic treatment of distal radius epiphyseal fracture we can list Super Inductive System (SIS), a therapy based on the interaction between the electric field and the human body with the improvement of the healing process by acting on the pathophysiological stages of bone callus. Material and method. A clinical case study was performed on a 28-year-old patient, hospitalized and treated in the neurosurgery department of the Constanta County and Emergency Hospital for a polytrauma by road accident (passenger) with amyelotic cervical vertebral trauma, thoracic trauma and trauma to the right upper limb, subsequently performing 12 SIS therapy sessions at the Balneal and Rehabilitation Sanatorium of Techirghiol. CT examination of the cervical spine reveals fractures of C4 vertebra (the blade and pedicle) and C5 vertebra (vertebral body, lamina and pedicle). Right forearm radiography reveals fracture of the right radial styloid. After conservative treatment of the cervical injury and orthopedic treatment of the upper limb injury, the clinical evolution is favorable, allowing the patient to be discharged and allowed to do 12 sessions of SIS therapy, 3 times a week, within 4 weeks. The subsequent clinical and paraclinical evolution was favorable for the outpatient orthopedic ambulatory reevaluation performed at 5 weeks. Results and discussions. Due to the type of fracture of the radial distal epiphysis (linear fracture without displacement), absence of comorbidities and young age, led to the indication of orthopedic treatment with immobilization in the antebrachio-palmarcast, which allowed subsequent physiotherapy.
