“…The observation of a radiolucent mass, periosteal reaction [29,42] and calcification in elbow radiograph; soft tissue masses of varying echogenicity under ultrasound [28]; slower rate of transmission than that of the healthy side under EMG [44]; delayed latency and low amplitude; intermediate signal increase under T1-weighted MRI; and high signal increase in T2-weighted imaging all support the diagnosis of PIN palsy secondary to lipoma. However, definitive diagnosis should be established through the identified presence of broad-based multi-lobular masses covered with thin fibrous tissue in contact with a bone and parosteal changes in the bone bordering the lesion in histopathological examination [42].…”

Several different pathologies may play a role in the etiology of posterior interosseous nerve (PIN) palsy such as trauma, radial tunnel syndrome, tumors, vasculitis, septic arthritis, and rheumatoid synovitis. The most common atraumatic factor is the compression of the nerve through its anatomic path. Parosteal lipoma around the proximal radius is the leading solid tumor seen among the neoplastic lesions. Although it is common, there are only case reports or few case series reported in the current literature and a comprehensive review is missing. Herein a rare case of PIN palsy due to parosteal lipoma of the proximal radius is presented together with a thorough literature review. A 48-year-old woman was presented with elbow pain and wrist drop that lasted for ten months. Electrodiagnostic and imaging findings lead to a diagnosis of PIN palsy due to parosteal lipoma seated over the proximal radius. Total surgical excision was performed, and the patient had been followed up for one year. Removal of the lipoma failed to recover the patient's symptoms. We reviewed all the reported cases and discussed, epidemiology, clinical findings, imaging studies, electrodiagnostic studies, pathology, treatment and prognosis of PIN palsy due to parosteal lipoma.

“…However, several studies in the literature affirm this wide variability in the percentage of innervations. Bevelaqua et al43 elucidated the relationship with C 6 -C 7 roots using needle electromyography. The axillary nerve is one of the terminal branches of the posterior cord of the brachial plexus and usually contains fibers from C 5 to C 6 ventral rami.…”

Background:Nonspecific shoulder pain has a high prevalence in older adults and causes functional alterations. Furthermore, there are difficulties in establishing a clinical diagnosis, effective treatments are lacking, and little evidence has been found regarding the use of invasive physical therapy techniques in this age group.Purpose:To determine the efficacy of a single physical therapy intervention with deep dry needling (DDN) on latent and active myofascial trigger points (MTrPs) in older adults with nonspecific shoulder pain.Methods:This pilot study is a single-blind, randomized, controlled clinical trial that included 20 participants, aged 65 years and older, who were diagnosed with nonspecific shoulder pain. The study was approved by the Clinical Research Ethics Committee of the area. Participants were recruited at their homes or at a care center and were randomly assigned into either an experimental group (n = 10), which received a session of DDN on 1 active and 1 latent MTrP of the infraspinatus muscle, or a control group (n = 10), which received a session of DDN on only 1 active MTrP. A blind examiner assessed the pain intensity, pain pressure threshold on the anterior deltoid, and extensor carpi radialis brevis muscles and grip strength before, immediately after, and 1 week after the intervention.Results:Statistically significant differences (P < .05) in the pressure pain thresholds (PPTs) of the extensor carpi radialis brevis were found in the experimental group in both posttreatment assessments. Moreover, the effect size values (d Cohen) varied from small for grip strength (0.017-0.36) to moderate for the pain intensity (0.46-0.78) and PPT in the anterior deltoid (0.49-0.66) and to large for the PPT in the extensor carpi radialis brevis (1.06-1.58).Conclusions:A single physical therapy intervention with DDN on 1 latent MTrP, in conjunction with 1 active MTrP, in the infraspinatus muscle may increase the PPT of the extensor carpi radialis brevis muscle area immediately following and 1 week after the intervention in older adults with nonspecific shoulder pain.

As a result of its proximity to the humeral shaft, as well as its long and tortuous course, the radial nerve is the most frequently injured major nerve in the upper limb, with its close proximity to the bone making it vulnerable when fractures occur.Injury is most frequently sustained during humeral fracture and gunshot injuries, but iatrogenic injuries are not unusual following surgical treatment of various other pathologies.Treatment is usually non-operative, but surgery is sometimes necessary, using a variety of often imaginative procedures. Because radial nerve injuries are the least debilitating of the upper limb nerve injuries, results are usually satisfactory.Conservative treatment certainly has a role, and one of the most important aspects of this treatment is to maintain a full passive range of motion in all the affected joints.Surgical treatment is indicated in cases when nerve transection is obvious, as in open injuries or when there is no clinical improvement after a period of conservative treatment. Different techniques are used including direct suture or nerve grafting, vascularised nerve grafts, direct nerve transfer, tendon transfer, functional muscle transfer or the promising, newer treatment of biological therapy.Cite this article: Bumbasirevic M, Palibrk T, Lesic A, Atkinson HDE.
