Background: The purpose of this study was to determine the predictive value of the clenched fist stress views in identifying scapholunate ligament injuries. Methods: An institutional review board–approved retrospective chart review was conducted of adult patients who underwent diagnostic arthroscopy with a ligamentous wrist injury from 2015 to 2020. Standard posteroanterior, lateral, and clenched fist stress radiographs were reviewed and scapholunate ligament gaps recorded. Results: A total of 124 patients were included, of which 88 had normal standard radiographs and clenched fist radiographs. The positive predictive value of the clenched fist view was 69%, whereas the negative predictive value was 58%. The sensitivity of the clenched fist view was 40%, while the specificity was 82%. Of those patients with a negative clenched fist view, 42% were found to have an arthroscopic Geissler classification of 3 or higher scapholunate ligament injury. Conclusions: Despite the emphasis on stress radiographic views, a normal stress clenched fist view does not preclude arthroscopic findings of a Geissler class 3 or greater injury in symptomatic patients. The sensitivity of a clenched fist view is only 40%. These findings question the utility of stress radiographs when assessing for scapholunate ligament injuries.

AbstractBackground The field of arthroscopy has exponentially grown in the past decade, especially in the realm of upper extremity surgery.Description The use of smaller cameras and further advancements in arthroscopy technology have allowed innovative expansion in the application of arthroscopy in small joints.Clinical Relevance Included in the advancements is the NanoScope, a 1.9-mm flexible scope specifically designed for small joint visualization.

Background In advanced pharyngoesophageal cancer patients, a critical event is represented by the failure of primary reconstruction with exposure of the carotid artery and partial or total defect of the cervical esophagus. For these high-risk patients, a partitioned pectoralis major musculocutaneous (PMMC) flap can prevent carotid blowout and provide skin for simultaneous esophageal reconstruction. Methods Twenty-six patients needing pharyngoesophageal reconstruction together with coverage of carotid artery exposure were included in this retrospective case series. The patients were treated with a partitioned PMMC flap, based on the branching pattern of the pectoral branch of the thoracoacromial artery and the perforators of the pectoralis major muscle, to simultaneously reconstruct the defect and provide coverage for the carotid artery. Results In 25 patients, the partitioned PMMC flap reconstructions resulted in complete wound healing without occurrence of carotid blowout syndrome or fistula formation. Minor complications as partial flap necrosis (7.7%) and strictures formation (7.7%) were recorded but did not compromise reconstruction. Twenty-two patients were able to adopt a semisolid diet, and 4 had recurrence of cancer. Conclusions The partitioned PMMC flap reconstruction represents a useful salvage solution to simultaneously restore the continuity of the alimentary tract and provide reliable coverage for the exposed carotid artery.

Abstract Central giant cell granuloma (CGCG) is a relatively uncommon benign bony lesion accounting for approximately 7% of all non-neoplastic lesions of the jaw. The clinical behavior of CGCG can vary from a slow-growing, painless lesion to fast-growing and locally destructive. When such a lesion involves the mandible, this can be quite debilitating for the patient, inhibiting oral intake and requiring an extensive resection and bone graft reconstruction. The authors present a case of effectively decreasing the surgical morbidity associated with a large and rapidly growing CGCG of the mandible in a pediatric patient. Neoadjuvant immunotherapy with denosumab (human monoclonal antibody) facilitated treatment of the tumor without the need for a large resection which would have otherwise necessitated a vascularized bony mandibular reconstruction. Consideration of neoadjuvant medical management of CGCG as the primary treatment is advocated.

Abstract Cranio-orbital trauma is an uncommon yet devastating injury, especially one in the setting of a high-energy gunshot wound. Such injuries were historically reported in the setting of military conflict, and are associated with vision-threatening complications, often resulting in anophthalmos. The authors report a case of a self-inflicted gunshot wound to the eye, which requires orbital enucleation with exposed frontal lobe dura. To address the exposed dura, the extraocular muscles were utilized from the enucleation procedure to cover the defect in the acute setting prior to final staged reconstruction.

AbstractThere has been a shift in recent years toward a growing popularity of implant-based breast reconstruction, especially in the setting of increased frequency of concurrent contralateral prophylactic mastectomy. Advancements in implant safety and technology have also allowed for an expanding implant reconstruction practice across the country. The traditional approach is immediate two-stage implant reconstruction with placement of a tissue expander within a subpectoral pocket. The introduction of acellular dermal matrix has revolutionized implant-based breast reconstruction, allowing surgeons the opportunity to minimize morbidity while maximizing aesthetic outcomes. There have also been advances in the management of postoperative pain control as well as secondary revision surgery.

» Targeted muscle reinnervation allows for the creation of additional electromyographic signals for a myoelectrically controlled prosthesis in patients who have undergone an upper-extremity amputation. » Targeted muscle reinnervation shows promise in addressing neuroma pain in both the upper and lower extremities. » Areas of further research include targeted sensory reinnervation as well as use in pediatric patients. » Osseointegration remains a challenge in need of further research given the high risk of infection.
