Brachial plexus injuries (BPIs) caused by shoulder dislocation usually have a transient character and tend to resolve spontaneously. However, in some patients the symptoms can persist and require operative intervention. This work aims to determine the risk factors for persistent BPIs resulting from shoulder dislocation. The study comprised 73 patients (58 men, 15 women; mean age: 50 years) treated operatively between the years 2000 and 2016 for persistent BPIs resulting from shoulder dislocation. Patient age, gender, type of initial trauma, number of affected nerves, presence of accompanying injuries, and time interval from dislocation to its reduction were analysed...

A 76-year-old male presented for reverse total shoulder arthroplasty (TSA) in the beach chair position. A preoperative interscalene nerve catheter was placed under direct ultrasound-guidance utilizing a posterior in-plane approach. On POD 2, the catheter was removed. Three weeks postoperatively, the patient reported worsening dyspnea with a subsequent chest X-ray demonstrating an elevated right hemidiaphragm. Pulmonary function testing revealed worsening deficit from presurgical values consistent with phrenic nerve palsy...

BACKGROUND The complication rate of central venous catheterization ranges from 4% to 35%. Brachial plexus injury can occur, mostly on the same side as the catheterization, without affecting the contralateral brachial plexus. CASE REPORT A 71-year-old woman received placement of a vein hemodialysis catheter via right internal jugular vein. Five days after the cannulation, she complained of contralateral burning pain and numbness at the ulnar side of her left forearm. On the next day, the pain increased and extended to her left shoulder girdle and whole left arm, despite use of analgesics...

BACKGROUND: Most brachial plexus birth injuries (BPBI) are caused by traction on the brachial plexus during a difficult delivery. Fortunately, the possibility of complete recovery from such an incident is relatively high, with only 10% to 30% of patients having prolonged and persistent disability. These patients have muscle imbalances and co-contractions typically localized around the shoulder and elbow. These imbalances and co-contractures cause abnormal motor performances and bone/joint deformities...

The incidence of combined neurovascular injuries among patients with high-energy shoulder trauma ranges from 27% to 44%. However, the presentation of an axillary artery pseudoaneurysm (PSA) due to shoulder dislocation without an associated osseous fracture is a very rare condition. Moreover, treatment of combined neurologic and vascular injuries of the shoulder remains controversial. Additionally, minimally invasive treatments such as thrombin injection have been mainly evaluated in patients with iatrogenic femoral artery PSAs...

Drug bioavailability to the developing brain is a major concern in the treatment of neonates and infants as well as pregnant and breast-feeding women. Central adverse drug reactions can have dramatic consequences for brain development, leading to major neurological impairment. Factors setting the cerebral bioavailability of drugs include protein-unbound drug concentration in plasma, local cerebral blood flow, permeability across blood-brain interfaces, binding to neural cells, volume of cerebral fluid compartments, and cerebrospinal fluid secretion rate...

Background Context Intraoperative neurophysiological monitoring (IONM) has gained rather wide-spread acceptance as a method to mitigate risk to the lumbar plexus during Lateral Lumbar Interbody Fusion (LLIF) surgery. The most common approach to IONM involves using only electromyography (EMG) monitoring, and the rate of postoperative deficit remains unacceptably high. Other test modalities, such as transcranial electric motor-evoked potentials (tcMEPs) and somatosensory-evoked potentials (SSEPs), may be more suitable for monitoring neural integrity but they have not been widely adopted during LLIF...

OBJECTIVE: To identify a fluoroscopic bony landmark for safe percutaneous axillary artery cannulation. BACKGROUND: No bony landmarks exist to guide safe percutaneous axillary artery cannulation, which is an important alternate access site for catheter-based procedures in selected patients. METHODS: We retrospectively analyzed 51 consecutive percutaneous axillary artery sheath angiograms and attempted to correlate a fixed bony landmark to the proximal end of the third part of the artery...

Introduction Oblique lumbar interbody fusion (OLIF) is a newer procedure that avoids the psoas and lumbosacral plexus due to its oblique trajectory into the retroperitoneal space. While early experience with OLIF is reassuring, the longer-term clinical efficacy has not been well established. The purpose of this study was to describe two-year clinical outcomes with OLIF performed by a single surgeon during the learning curve without the aid of the neuromonitoring. Materials and methods Chart review was performed for the consecutive patients who underwent OLIF by a single surgeon...

INTRODUCTION: Surgical management of spontaneous subclavian thrombosis due to venous thoracic outlet syndrome (vTOS) results in durable relief of symptoms. The need to re-operate is rare. We report our experience with re-operation for vTOS. METHODS: Patients evaluated for vTOS between 1996 and 2016 were identified in a prospective database. Data recorded included demographics, initial presentation, initial surgery, recurrent presentation, re-operation, and final outcomes...

OBJECTIVE The purpose of this study was to compare shoulder abduction and external rotation (ER) after single-nerve repair of the upper trunk alone versus dual-nerve repair of both the upper trunk and the suprascapular nerve. METHODS A retrospective chart review of a single surgeon's experience repairing obstetrical brachial plexus injuries between June 1995 and June 2015 was performed. Eight patients underwent repair of the upper trunk alone, and 10 patients underwent repair of the upper trunk and the suprascapular nerve...

BACKGROUND: The incidence of Gestational Diabetes Mellitus (GDM) is rising in all developed countries. This study aimed at assessing the short-term economic burden of GDM from the Italian healthcare system perspective. METHODS: A model was built over the last pregnancy trimester (i.e., from the 28th gestational week until childbirth included). The National Hospital Discharge Database (2014) was accessed to estimate delivery outcome probabilities and inpatient costs in GDM and normal pregnancies (i...

AIM: Arthrodesis of the shoulder joint is a radical event, so it is difficult to explain its significance to patients. It has been the last resort in hopeless cases. Knowledge of long-term results and evaluation of advantages and disadvantages seems to be helpful in this regard. METHODS: Eleven patients with mean age of 45 (31 - 58) years were operated between 2000 and 2013. All patients could be included in the investigation (FU mean 8.5 [3 - 16] years; 8 male and 3 female; right 9, left 2)...

If a partial contralateral C 7 nerve is transferred to a recipient injured nerve, results are not satisfactory. However, if an entire contralateral C 7 nerve is used to repair two nerves, both recipient nerves show good recovery. These findings seem contradictory, as the above two methods use the same donor nerve, only the cutting method of the contralateral C 7 nerve is different. To verify whether this can actually result in different repair effects, we divided rats with right total brachial plexus injury into three groups...

To understand the neural mechanisms underlying the therapeutic effects of crossing nerve transfer for brachial plexus injuries in human patients, we investigated the cortical responses after crossing nerve transfer in mice using conventional and tomographic optical imaging. The distal cut ends of the left median and ulnar nerves were connected to the central cut ends of the right median and ulnar nerves with a sciatic nerve graft at 8 weeks of age. Eight weeks after the operation, the responses in the primary somatosensory cortex (S1) elicited by vibratory stimulation applied to the left forepaw were visualized based on activity-dependent flavoprotein fluorescence changes...

BACKGROUND: Long-term morbidity after multimodal treatment for rectal cancer is suggested to be mainly made up by nerve-injury-related dysfunctions. Stereotactic navigation for rectal surgery was shown to be feasible and will be facilitated by highlighting structures at risk of iatrogenic damage. The aim of this study was to investigate the ability to make a 3D map of the pelvic nerves with magnetic resonance imaging (MRI). METHODS: A systematic review was performed to identify a main positional reference for each pelvic nerve and plexus...

Adult brachial plexus injuries frequently lead to significant and permanent physical disabilities. Investigating the mechanism of the injury using biomechanical approaches may lead to further knowledge with regard to preventing brachial plexus injuries. However, there are no reports of biomechanical studies of brachial plexus injuries till date. Therefore, the present study used a complex three-dimensional finite element model (3D-FEM) of the brachial plexus to analyze the mechanism of brachial plexus injury and to assess the validity of the model...
