E Vergara-Amador, F Vela-Rodríguez
The independent neurovascular anatomy of the long head of the triceps brachii and its suitability as a free muscle transfer have been extensively studied. Instead muscle transposition of the long head of the triceps brachii to enhance elbow flexion has been rarely described. We describe in this paper two cases of injury of brachial plexus sequel in which transposition was performed only on the long head of the triceps. The elbow flexion was improved, the extension was preserved.

Iatrogenic nerve palsies due to faulty positioning on the operating table are commonly seen over the elbow and popliteal fossa. However, injury to the brachial plexus (BP) is rarely encountered and is a recently reported phenomenon due to the increasing number of complex surgeries including hepatobiliary surgical procedures. Brachial plexus injury (BPI) needs to be recognized as a potential complication of prolonged abdominal surgery. The present case report highlights the potential for BPI and its early recognition, management, and prevention in complex prolonged abdominal surgical procedures...

BACKGROUND: The aim of this study was to investigate outcomes after surgery for brachial plexus injury (BPI), not only motor outcomes but also the quality of life of the patients. METHODS: We operated on 128 consecutive patients with BPI from 1992 to 2012. We documented the information on the injured nerve, level of injury, type of treatment used, timing of surgery, patient age, and preoperative and postoperative motor deficits. In 69 patients who agreed to participate in a quality of life study, additional assessments included functionality, pain, quality of life, patient satisfaction, and psychosocial health...

BACKGROUND: The vast majority of studies emphasize the greater morbidity/mortality for elective spine surgery in morbidly obese patients. METHODS: This review focuses on the increased morbidity/mortality of performing elective spinal operations in morbidly obese patients. There are two definitions of morbid obesity; a body mass index (BMI) of equal to or greater than 35 plus two major comorbid factors (e.g., hypertension, diabetes, etc.) or a BMI (morbidly obese III) of =≥40 kg/m(2)...

The Duchenne Muscular Dystrophy (DMD) is a genetic disorder characterized by the absence of dystrophin protein, causing severe myopathy from increases of oxidative stress. Injuries of intestinal muscle can compromise the myenteric plexus. This study aimed to evaluate the disorders occurred in the muscular layer and in the acetylcholinesterase myenteric neurons (ACHE-r) of ileum of mdx mice, and the effects of supplementation with ascorbic acid (AA) in both components. 30 male mice C57BL/10, and 30 male mice C57BL/10Mdx were separated according to the age and treatment (n=10/group): 30-days-old control group (C30); 30-days-old dystrophic group (D30); 60-days-old control group (C60); 60-days-old dystrophic group (D60); 60-days-old control group supplemented with AA (CS60); and 60-days-old dystrophic group supplemented with AA (DS60)...

While upper limb nerve transfers were first described and performed several years ago, they have seen expanded use in the past 20 years. Initially indicated for surgical repair of brachial plexus injuries with nerve root avulsion, the indications have been extended to post-ganglionic lesions because of the excellent results of certain intraplexus nerve transfers. The traditional nerve repair techniques - primary suture and nerve grafting - form the basis of nerve surgery. Although nerve transfer does not replace them, they are a useful supplement as they provide a targeted approach to reinnervation and recovery of key functions of the upper limb...

BACKGROUND: Psychiatric patients are often kept immobilized during hospitalization to avoid self-inflicted injuries and danger to third parties. Inadequate positioning can lead to brachial plexus injuries (BPI). OBJECTIVE: To present a series of 5 psychiatric patients with BPI after being left sedated and restrained for prolonged periods of time during hospitalization. METHODS: We retrospectively reviewed the charts of 5 psychiatric patients with iatrogenic BPI referred by other institutions to our service...

BACKGROUND: Previous animal studies demonstrated that the sensory and motor functions in ipsilesional upper limbs that had been reconstructed by CC7 transfer eventually associated with the contralesional brain cortices that had originally mediated the functions of the ipsilesional upper limbs before brachial plexus injury (BPI). Our hypothesis was that the same findings would be seen in humans. METHODS: Four patients with total BPI treated with CC7 transfer were included...

We report the study of the anatomical feasibility of transferring the nerve to the brachialis muscle to the upper medial head motor branch that innervate the triceps, and outcomes of such transfers in restoring elbow extension in five patients with posterior cord lesion of the brachial plexus. The length of the branches to the brachialis muscle measured 7.6 cm and the triceps upper medial head motor branch was 5 cm in 10 adult cadavers. Five male patients were treated with this transfer 5 months after the injury (range 4 to 6 months) after posterior cord injury of the brachial plexus with a mean follow-up of 31 months (range 28 to 36 months)...

Recent advancement in electrocorticography (ECoG)-based brain-computer interface technology has sparked a new interest in providing somatosensory feedback using ECoG electrodes, i.e., cortical surface electrodes. We conducted a 28-day study of cortical surface stimulation in an individual with arm paralysis due to brachial plexus injury to examine the sensation produced by electrical stimulation of the somatosensory cortex. A high-density ECoG grid was implanted over the somatosensory and motor cortices. Stimulation through cortical surface electrodes over the somatosensory cortex successfully elicited arm and hand sensations in our participant with chronic paralysis...

BACKGROUND: Obstetrical brachial plexus palsy is a common birth injury to nerves passing through the brachial plexus that may result in structural and functional abnormalities. Individual joint trajectories from kinematic analyses have been used to evaluate the source and extent of abnormalities. Here, two summary measures of limb kinematics were utilized: 1) the Arm Profile Score summarizing upper limb joint kinematic abnormalities from a typical pattern across a task, and 2) the recently developed Multi-joint Coordination Measure using principal component analysis to characterize typical coordination of multiple joints throughout a task and compute deviations in time and space...

Although several donor nerves can be chosen to repair avulsed brachial plexus nerve injury, available nerves are still limited. The purpose of this study is to validate whether the vagus nerve (VN) can be used as a donor. Eighteen Sprague-Dawley male rats were divided into three groups (n = 6). The right musculocutaneous nerve (McN) was transected with differing subsequent repair. (1) HS-VN group: a saphenous nerve (SN) graft-end was helicoidally wrapped round the VN side (epi-and perineurium was opened) with a 30 ° angle, distal SN end was coapted to the McN with end-to-end repair...

Trichobezoar is a rare condition whereby a hairball is found in the human stomach or gastrointestinal tract, most frequently in young women, mainly in association with a psychiatric disorder. Trichobezoar cases have also been reported in the bladder and represent a rare complication of foreign bodies, called "hair nidus or hair ball," in patients with chronic catheter. Approximately 10% to 15% of patients on long-term urethral catheter or clean intermittent self-catheterization develop urinary tract stones...

Bacterial meningitis is an inflammatory disease of the meninges of the central nervous system (CNS). Streptococcus pneumoniae (S. pneumoniae), Neisseria meningitidis, and Haemophilus influenzae are the major bacterial pathogens causing meningitis with S. pneumoniae being responsible for two thirds of meningitis cases in the developed world. To reach the CNS following nasopharyngeal colonization and bacteraemia, the bacteria traverse from the circulation across the blood brain barrier (BBB) and choroid plexus...

Glenohumeral dysplasia can occur in brachial plexus birth palsy due to an imbalance of muscle forces. Most commonly this occurs in C5-C6 injuries where the shoulder external rotators are weak compared with the shoulder internal rotators. Treatment of the dysplasia with open reduction of the glenohumeral joint in combination with rebalancing the muscles can improve the development of the joint. Furthermore, the tendon transfer can improve shoulder function by decreasing the internal rotation forces about the shoulder while increasing the external rotation forces...
