Article Abstract
Background: Cervical nerve root avulsion is a well-documented result of high-velocity motor vehicle accidents (MVAs). In up to 21% of cases, preganglionic cervical root avulsion can result in a complex regional pain syndrome (CRPS) impacting the quality of life for patients already impaired by motor, sensory, and autonomic dysfunction. The optimal treatment strategies include repeated stellate ganglion blocks (SBGs).
Case Description: A 43-year-old male sustained a high-velocity MVA resulting in the left C8 nerve root avulsion. This resulted in weakness in the C8 distribution, tactile allodynia, and dysesthesias. The magnetic resonance imaging demonstrated an abnormal signal ventral to the C8-T1 level. As the patient was not considered a candidate for surgical intervention secondary to the attendant brachial plexus injury, a C7-C8 epidural steroid injection was performed; this did not provide improvement. Before placing a spinal cord stimulator, the patient underwent a series of six ultrasound-guided SBGs performed 2 weeks apart; there was 75% improvement in pain and strength. Six years later, the patient continues to do well while receiving SBGs 4 times a year.
Conclusion: A preganglionic cervical nerve root avulsion should not be a contraindication for a stellate ganglion block in a patient with established CRPS.

Dental trauma is one of the relatively common emergencies in clinical dental practice, with a high incidence rate, and the maxillary central incisors are the most frequently affected. This article reports a case of a 17-year-old female patient who suffered traumatic complete avulsion of teeth 11 and 21, with tooth 21 lost after avulsion. The prognosis for replantation was poor due to the absence of the buccal alveolar bone wall of tooth 11.

Background: Transfer of intercostal nerves to the radial nerve branch innervating the long head of the triceps muscle for elbow extension is indicated in patients with traumatic brachial plexus palsy that is either the pan-plexus type or C5-C7 palsy with no triceps muscle function. The procedure aims to restore triceps muscle function through the use of the intercostal nerves, which are expendable nerves, as donors.
Description: The procedure is performed by first identifying the third to fifth intercostal nerves and coaptating them to the radial nerve branch innervating the long head of the triceps muscle.
Long-term Follow-up of Apexogenesis, Root Canal Obliteration and External Replacement Resorption Following Tooth Replantation.

Dental replantation is the treatment of choice for tooth avulsion; however, complications such as root canal obliteration, pulp necrosis and tooth resorption can arise, influenced by factors like extra-alveolar time and the storage medium in which the tooth was maintained. This case report discusses a seven-year-old child who experienced a traumatic avulsion of a permanent maxillary right central incisor with incomplete root formation. While the tooth was successfully replanted and both pulp vitality and complete root formation (apexogenesis) were initially maintained, the tooth later developed root canal obliteration and ankylosis, followed by external replacement root resorption.

Background Surgical decisions for traumatic brachial plexus injury (TBPI) depend on the severity of nerve root injury, especially total root avulsion and partial root avulsion, determined with MRI and intraoperative findings. However, the use of quantitative MRI indexes to distinguish normal roots, total root avulsion, and partial root avulsion remains to be explored. Purpose To develop a diagnostic system using paraspinal muscle volumetric segmentation in MRI assessments of TBPI.

Purpose: The Narakas classification describes brachial plexus birth injury (BPBI) according to nerve root injury by the pattern of motor weakness on clinical examination. However, it is unknown whether the classification truly corresponds to the described nerve roots. The distribution of nerve root injuries on magnetic resonance imaging (MRI) in infants with BPBI was compared with the clinical classification.
