Alessandro Marra
Pancoast or superior pulmonary sulcus tumour is a subset of lung carcinoma that invades the structures of the thoracic inlet - first ribs, distal roots of the brachial plexus, stellate ganglion, vertebrae, and subclavian vessels. The first symptom is usually shoulder pain; consequently, most patients are initially treated for osteoarthritis. Late diagnosis is common. Success of therapy depends on an accurate staging: standard imaging with CT scan of the chest, PET-CT scan, brain MRI are needed to rule out distant metastases, endobronchial ultrasound-guided needle biopsy (EBUS-TBNA) or mediastinoscopy are mandatory for reliable nodal staging...

BACKGROUND: Horner's syndrome is comprised of a set of symptoms caused by a permanent or transient ipsilateral sympathetic trunk lesion or paralysis. It may occur after numerous pathologies in the cervical region, epidural, spinal anaesthesia, and interscalene, transscalene, supraclavicular, or infraclavicular brachial plexus block. The aim of this randomised, prospective clinical study was to evaluate the effect of the interscalene brachial plexus block (IBPB) technique on the occurrence rate of Horner's syndrome and identify contributing risk factors...

The suprascapular artery is normally a branch of the thyrocervical trunk of the subclavian artery. During dissection of the left upper limb of a female cadaver, aged 70 years and fixed in 10% formalin solution, the suprascapular artery was observed aberrantly arising from the first part of the axillary artery. Later, it coursed obliquely behind the clavicle bone and brachial plexus to reach the suprascapular notch, where it was accompanied by the suprascapular nerve. Then, both suprascapular nerve and artery anomalously traversed beneath the transverse scapular ligament...

Research on brain function after brachial plexus injury focuses on local cortical functional reorganization, and few studies have focused on brain networks after brachial plexus injury. Changes in brain networks may help understanding of brain plasticity at the global level. We hypothesized that topology of the global cerebral resting-state functional network changes after unilateral brachial plexus injury. Thus, in this cross-sectional study, we recruited eight male patients with unilateral brachial plexus injury (right handedness, mean age of 27...

An 8-year-old castrated male cat presented with acute ataxia and paresis in all four limbs. The cat also exhibited signs of autonomic nervous system impairment. Magnetic resonance imaging revealed swelling of the brachial plexuses bilaterally. Despite treatment, the cat died after 10 days of treatment. A postmortem examination revealed swollen radial nerves and cervical nerve roots in which infiltration of inflammatory cells was histologically confirmed. Additionally, lymphocytic infiltration was found around the blood vessels of the sciatic nerve bundle and the vagus nerve...

BACKGROUND AND OBJECTIVES: Retroclavicular block is designed to overcome the negative aspects of the commonly utilized ultrasound-guided parasagittal approach to the infraclavicular block. However, this approach necessitates the needle traversing an area posterior to the clavicle inaccessible to ultrasound wave conduction. This study sought to document the structures vulnerable to needle injury during a retroclavicular block. METHODS: A Tuohy needle was inserted using a retroclavicular approach to the infraclavicular block in 3 lightly embalmed cadavers followed by a catheter insertion 4 cm beyond the needle tip...

BACKGROUND AND OBJECTIVES: It has recently been proposed that an infraclavicular brachial plexus block (BPB) at the costoclavicular (CC) space may overcome some of the limitations of the lateral sagittal (LS) approach. In this study, we hypothesized that the CC approach will produce faster onset of sensory blockade of the 4 major terminal nerves of the brachial plexus than the LS approach. METHODS: Forty patients undergoing elective upper extremity surgery under a BPB were randomized to receive either the LS (Gp-LS, n = 20) or CC approach (Gp-CC, n = 20) for infraclavicular BPB...

REVIEW
Nicholas A Levine, Brandon R Rigby
Thoracic outlet syndrome (TOS) describes a group of disorders that are due to a dynamic compression of blood vessels or nerves, between the clavicle and first rib or cervical vertebral nerve roots. Individuals with TOS typically experience upper limb pain, numbness, tingling, or weakness that is exacerbated by shoulder or neck movement. The causes of TOS vary, and can include abrupt movements, hypertrophy of the neck musculature, and anatomical variations in which the brachial plexus roots pass through this musculature, edema, pregnancy, repeated overhead motions, the blockage of an artery or vein, or abnormal posture...

Background and purpose This case of a 42 year old woman with lower extremity Complex Regional Pain Syndrome (CRPS) after a twisting injury of the ankle, effectively treated with the addition of mirror therapy to a rehabilitation programme, prompted a literature review of both CRPS and mirror therapy. Mirror therapy is a newer adjunct to other forms of pain control and functional restoration for treatment of CRPS as well as other difficult clinical problems. This was a required group project as part of a university based course in chronic pain for healthcare workers...

Background: Our institution's traditional pain management strategy after shoulder arthroplasty has involved the utilization of postoperative patient-controlled narcotic analgesia. More recently, we have implemented a protocol (TLC) that utilizes a multimodal approach. The purpose of this study was to determine whether this change has improved pain control and decreased narcotic utilization. Methods: Patients undergoing primary total shoulder or reverse arthroplasty were retrospectively studied...

BACKGROUND AND OBJECTIVES: For superficial surgery of anteromedial and posteromedial surfaces of the upper arm, the medial brachial cutaneous nerve (MBCN) and the intercostobrachial nerve (ICBN) must be selectively blocked, in addition to an axillary brachial plexus block. We compared efficacy of ultrasound-guided (USG) versus conventional block of the MBCN and the ICBN. METHODS: Eighty-four patients, undergoing upper limb surgery, were randomized to receive either USG (n = 42) or conventional (n = 42) block of the MBCN and the ICBN with 1% mepivacaine...

BACKGROUND: Postoperative ipsilateral shoulder pain occurs in 37% to 68% of patients undergoing a thoracotomy. We examined whether interscalene brachial plexus block using a lower concentration of local anesthetic would reduce the incidence of post-thoracotomy ipsilateral shoulder pain with assessment of pulmonary function in patients who underwent a lung lobectomy. METHODS: Forty-four patients who underwent a lung lobectomy were randomly assigned to either the control or the interscalene block group...

CASE: An 80-year-old woman sustained a fracture-dislocation of the proximal aspect of the humerus with a near-complete brachial plexopathy, which was successfully managed acutely using a reverse shoulder arthroplasty (RSA) with repair of the greater and lesser tuberosities. The palsy, which was confirmed with nerve conduction studies, recovered uneventfully along with functional improvement of the shoulder. At the most recent follow-up, there was complete resolution of the plexopathy, with excellent, pain-free range of motion...

The perineural administration of alcohol or phenol results in protein denaturation and, consequently, neurolysis. This can produce long-lasting analgesia, with a duration of 3-6 months. Although neurolytic blocks for the brachial plexus have been described in multiple review articles and textbooks, they are rarely performed. As such, little is known about the efficacy and adverse effect profile of this commonly described treatment. In this article, we report the outcomes of a patient who underwent a left brachial plexus neurolytic block for the management of upper limb pain arising from a malignant peripheral nerve sheath tumor...

Isaacs syndrome is a rare peripheral nerve hyperexcitability syndrome. The painful discharges in Isaacs syndrome are abolished by the blockade of the neuromuscular junction but not by peripheral nerve blocks (PNB). However, the efficacy of PNB for intraoperative and postoperative analgesia among those with Isaacs syndrome is unknown. A 41-year-old woman with Isaacs syndrome underwent open reduction and internal fixation of radius fractures. Ultrasound-guided bilateral axillary brachial plexus blocks were performed, followed by general anesthesia...

Simulation in obstetrics is a widely accepted and valuable tool that benefits all levels of learners from medical students to maternal-fetal medicine subspecialists. What began as an adjunct to medical education now has a rapidly expanding role in acquisition of new and innovative procedures, team and unit training, and safety and quality initiatives. The number of obstetric simulation peer-reviewed reports has increased exponentially in recent years, yet only a small percentage of reports primarily addresses clinical outcomes...

The modified Steindler procedure-a reconstructive surgery used to restore elbow flexion following upper brachial plexus injuries-involves shifting the origins of the muscle groups responsible for wrist flexion and forearm pronation originating from the medial epicondyle to the proximal direction to be used as flexors of the elbow. In the postoperative rehabilitation, we focused on strengthening not only the transferred muscle but also the wrist extensor muscles as antagonist muscles. After reconstruction surgery for elbow flexion via the modified Steindler procedure for traumatic brachial plexus injury, we performed long-term rehabilitation to strengthen the antagonist muscles...
