Background The topographic arrangement of sensory receptors in the human elbow joint capsule is pertinent to their role in the transmission of neural signals. The signals from stimuli in the joint are concisely delivered via afferent pathways to allow recognition of pain and proprioception. Sensory receptors in the elbow joint include mechanoreceptors and free nerve endings acting as nociceptors, although the distribution of each of the structures has not been determined, despite their importance for the integrity of the joint. We therefore aimed to investigate the neuroanatomical distribution and densities of mechanoreceptors and free nerve endings in the capsule of the elbow, at the same time as considering surgical approaches that would result in the minimum insult to them. Methods Four elbow joint capsules were harvested from fresh cadavers. The specimens were carefully separated from adjacent osteoligamentous attachments and the capsular complex was stained with a modified gold chloride method. Evaluations of free nerve endings, and Golgi, Ruffini and Pacinian corpuscles were performed under an inverted light microscope. The number and density of each structure were recorded. Results Ruffini corpuscles observed to be the dominant mechanoreceptor type. No Golgi corpuscle was observed. Free nerve endings were found at the highest density at posterodistal sites, whereas mechanoreceptors were most frequent at bony attachment sites. Conclusions A consistent distribution pattern of articular sensory receptors was observed, which allows further understanding of elbow pathology. An awareness of the neuroanatomical distribution of sensory receptors in the elbow joint capsule may allow their preservation during surgical procedures for elbow joint pathology.

Background: Calcification around the shoulder joint usually occur inside or around the tendons of the rotator cuff. We herein report on a case of global hypertrophic calcification of shoulder joint capsule in a patient with Rheumatoid arthritis. Case Report: An 86 years-old male with a long-standing history of seropositive Rheumatoid arthritis. The treatment for his Rheumatoid arthritis included Methotrexate and Hydroxychloroquine initially, but due lack of control, adalimumab was added with excellent control of his arthritis. He has progressively experienced an increasing pain and stiffness in his shoulders, in addition to an increasing limitation of shoulder movement. Magnetic Resonance Imaging revealed severe arthritis with remoulding deformity with extensive capsular calcification, intra-articular loose-bodies. Discussion: This phenomenon of calcification of shoulder capsule has not been reported before. The pathophysiology of calcific tendinopathy of the shoulder remains controversial. The calcific deposits consist of poorly-crystallized hydroxyapatite. Conclusion: Global hypertrophic calcification of shoulder joint capsule is unique and unreported in the literature. We can postulate that the long-standing inflammation of the synovial lining of the capsules had a major part. Moreover, Diabetes Mellitus, smoking, and repetitive manoeuvres are recognized contributing factors as well for similar conditions. Genetic predisposition seems to play a role as well. We think all those have played part in the development of this unprecedented presentation. Management should be tailored to target specific symptoms for pain, rigidity, and decreasing calcification size. Several options are available, including Kinesiotherapy, electrotherapy modalities, iontophoresis, electroshock wave therapy, and finally surgical approaches for progressive and refractory cases.

We have examined the initial innervation of the head skin in Xenopus laevis embryos which is by two classes of trigeminal mechanoreceptor with beaded ‘free’ nerve-endings. By recording receptive areas electrophysiologically and staining peripheral sensory neurites with horseradish peroxidase, we have shown that ‘movement detector’ neurites from one trigeminal ganglion do not normally cross the dorsal midline of the head to innervate areas of skin on the opposite side. However, if one trigeminal ganglion is removed before peripheral innervation starts, movement detector neurites from the intact side will now cross the midline to innervate contralateral skin. These observations suggest a specific competitive interaction between movement detector neurites during their innervation of head skin. The second class of receptor, ‘rapid transient’ detectors, have a different pattern of innervation, crossing the midline in both normal and operated animals.

Lateral Elbow

The anconeus muscle is a small and minor functioning muscle located at the posterolateral elbow region. It helps forearm extension and tightening of the joint capsule. Despite its limited functions, pathologies of the anconeus muscle can mimic other abnormalities of the elbow joint. Here, we report a rare case of a traumatic anconeus muscle contusion in a 15-year-old boy due to falling during dance. MRI showed contusion in the anconeus muscle, as well as strain in the ulnar collateral ligament and edema in the coronoid process of the ulna. To our knowledge, this is the first described case of traumatic anconeus muscle contusion in the literature. The presence of long-lasting lateral elbow pain in trauma cases without fracture should alert clinicians to consider anconeus muscle abnormalities. MRI is the best modality for diagnosis in these cases.
