Lymphoma involvement of peripheral nerves is rare and it may mimic benign neurogenic tumors or neuropraxic injury. This study presents three patterns of presentations in four patients with neurolymphomatous involvement of their peripheral nerves. We reviewed the clinical records of four patients who underwent exploratory brachial plexus surgery (n = 1), pronator tunnel decompression (n = 1) and peripheral nerve exploration (n = 2) and subsequently found to have neurolymphomatosis (NL). Histological diagnoses were diffuse large B-cell lymphoma (n = 3) and NK/T-cell lymphoma (n = 1)...

BACKGROUND: Surgical treatment of thoracic outlet syndrome (TOS) is necessary when non-surgical treatments fail. Complications of surgical procedures vary from short-term post-surgical pain to permanent disability. The outcome of TOS surgery is affected by the visibility during the operation. In this study, we have compared the complications arising during the supraclavicular and the transaxillary approaches to determine the appropriate approach for TOS surgery. METHODS: In this study, 448 patients with symptoms of TOS were assessed...

CLINICAL/METHODICAL ISSUE: Traumatic lesions of peripheral nerves and the brachial plexus are feared complications because they frequently result in severe functional impairment. The prognosis is greatly dependent on the correct early diagnosis and the right choice of treatment regimen. It is important to distinguish between open and closed injuries. STANDARD RADIOLOGICAL METHODS: Initial imaging must critically evaluate or prove nerve continuity and is commonly achieved by high-resolution ultrasonography...

Background: Conventional wisdom and the available literature demonstrate compromised outcomes following nerve reconstruction for traumatic brachial plexus palsy in the elderly. We present a 74-year-old male who was reconstructed with multiple nerve transfers for brachial plexus palsy after a ski accident. Methods: Triceps to axillary nerve transfer, spinal accessory to suprascapular nerve transfer, and ulnar to musculocutaneous nerve transfer were performed 16 weeks post injury. Results: At 11 years post-op, the patient could abduct to 65° and forward flex at M4 strength, limited only by painful glenohumeral arthritis...

Background: The goals of this study were to assess how preoperative and postoperative patients use their uninjured arm to compensate for adult brachial plexus injury (BPI) and to determine whether the Disabilities of Arm, Shoulder, and Hand (DASH) Questionnaire measures this compensation. Methods: Ten preoperative and 13 postoperative patients were enrolled in this qualitative-quantitative study. During the qualitative phase, patients were asked how they compensated because of BPI; responses were analyzed with grounded theory...

The transfer of a contralateral healthy seventh cervical spinal nerve root (cC7) to the recipient nerve in the injured side is considered a reliable and effective procedure for restoration of the physiological functions of an injured hand after brachial plexus root avulsion injury (BPAI). Growing evidence shows that the transhemispheric cortical reorganization is induced after cC7 nerve transfer surgery. However, little is known about the underlying molecular mechanism. Proinflammatory cytokines reportedly play an important role in the neural plasticity...

The America Society of Anesthesiology guidelines recommend multimodal analgesia that combines regional anesthetic techniques with pharmacotherapy to improve peri-procedural pain management and reduce opioid related complications. Commonly performed emergency procedures of the upper extremity such as fracture and dislocation reduction, wound debridement, and abscess incision and drainage are ideal candidates for ultrasound-guided (USG) regional anesthesia of the brachial plexus. However, adoption of regional anesthesia by emergency practitioners has been limited by concerns for potential complications and perceived technical difficulty...

Avulsion injuries of the brachial plexus with occipital condyle fractures are very rare and usually result from motor vehicle accidents. This paper presents an analysis of the case of a 24-year-old male patient who sustained both these injuries in a car accident. Computed tomography revealed a fracture of the right occipital condyle and a magnetic resonance scan showed spinal nerve disruption at the C3-C7 level on the left. The patient underwent conservative treatment.

OBJECTIVE Global brachial plexus lesions with multiple root avulsions are among the most severe nerve injuries, leading to lifelong disability. Fortunately, in most cases primary and secondary reconstructions provide a stable shoulder and restore sufficient arm function. Restoration of biological hand function, however, remains a reconstructive goal that is difficult to reach. The recently introduced concept of bionic reconstruction overcomes biological limitations of classic reconstructive surgery to restore hand function by combining selective nerve and muscle transfers with elective amputation of the functionless hand and its replacement with a prosthetic device...

BACKGROUND: Although open injuries involving the brachial plexus are relatively uncommon, they can lead to permanent disability and even be life threatening if accompanied by vascular damage. We present a case report of a brachial plexus injury in which the urgency of the situation precluded the use of any ancillary diagnostic examinations and forced a rapid clinical assessment. CASE PRESENTATION: We report a case of a Portuguese man who had a stabbing injury at the base of his left axilla...

PURPOSE: Medical Physics teams can now play a critical role to help plan and provide studied approaches for traumatic brachial plexus MR imaging (tbpMRI). This is especially important for coordination with uncommon applications, since it is challenging to select the right modality, parameters, and train technologists on the essential components. For this work, we started with a review of the medical literature, performed crossover/volunteer studies to bring tbpMRI to practice with greater image QC and protocol management...

BACKGROUND: Reconstruction after pan-plexus root avulsions often includes gracilis free functioning muscle transfer. For elbow flexion reconstruction, the free functioning muscle transfer distal tendon is inserted into the biceps tendon or more distally (i.e., flexor digitorum profundus/flexor pollicis longus tendons) for combined elbow and finger flexion; the theoretical drawback of the latter approach is weaker elbow flexion. The authors compared elbow flexion strength with a biceps tendon versus a flexor digitorum profundus/flexor pollicis longus tendon attachment to determine which insertion point resulted in better elbow flexion...

: Carrying heavy backpacks are often associated with shoulder discomfort or pain, loss of sensorimotor functions, and brachial plexus injuries that might hamper performance. Based on previous research, the cause of these symptoms could be tissue deformations of the brachial plexus and the subclavian artery caused by the shoulder straps. PURPOSE: To evaluate the changes in the upper extremity hemodynamic and neural function, and to assess how they are associated with brachial plexus tissue deformation during heavy load carriage...

BACKGROUND: Peripheral nerve injury is a common and important cause of morbidity and disability in patients who have suffered a traumatic injury, particularly younger people. Various different injuries can result in damage to specific nerves. In patients with multiple trauma, the prevalence of peripheral nerve injury is estimated at 2.8%, but can reach 5% with the inclusion of brachial plexus involvement. Physical examination, as well as the origin and location of the trauma, can indicate the nerve involved and the type of nerve damage...

BACKGROUND: Assessment of muscle atrophy and fatty degeneration in brachial plexus injury (BPI) could yield valuable insight into pathophysiology and could be used to predict clinical outcome. The objective of this study was to quantify and relate fat percentage and cross-sectional area (CSA) of the biceps to range of motion and muscle force of traumatic brachial plexus injury (BPI) patients. METHODS: T1-weighted TSE sequence and three-point Dixon images of the affected and non-affected biceps brachii were acquired on a 3 Tesla magnetic resonance scanner to determine the fat percentage, total and contractile CSA of 20 adult BPI patients...
