Catfish have the ability to inflict stings on their victims through spines located on their dorsal and pectoral fins. The stings of catfish can release toxins that have dermonecrotic, edemogenic, and vasospastic factors. In this case, a 56-year-old man suffered a catfish sting to his right thumb, which resulted in acute hand compartment syndrome and resultant hand fasciotomies. His hospital course was complicated by multiple irrigation and debridements, finger amputations, hand fluid cultures positive for Vibrio damsela , and eventual wrist disarticulation. The combination of envenomation, infection, and delayed presentation for treatment ultimately led to a hand amputation.

Background: Postoperative total joint arthroplasty complications place a tremendous burden on the health care system. The purpose of this study was to compare 30-day postoperative complication rates for surgeries in patients who received preoperative antiplatelet agents and/or anticoagulants to surgeries in a control group that did not receive antiplatelet agents and/or anticoagulants in the 90 days prior to undergoing a total joint arthroplasty. Methods: We retrospectively reviewed total hip or knee arthroplasties from November 2012 to March 2016. Surgeries were categorized into 4 groups depending on their preoperative antiplatelet and anticoagulant status. Complications between the groups were compared using chi-square analysis and Fisher exact test. Results: In this study, 1,726 arthroplasties in 1,544 patients were included. Superficial wound complications were the most common complication in all 4 groups (3.8% of surgeries), with no significant difference between the groups. A statistically significant difference was found in the number of prosthetic joint infections in the group of surgeries with no antiplatelets or anticoagulants compared to surgeries with both medications administered during the 90 days preoperatively (0.82% vs 5.13%, P =0.0003). No significant difference was found between the groups with regard to stroke, myocardial infarction, pulmonary embolism, or deep venous thrombosis. Conclusion: Surgeries for which both antiplatelets and anticoagulants were administered in the 90 days preoperatively had a statistically significantly higher rate of prosthetic joint infections compared to surgeries with neither medication administered preoperatively. Surgeons can use this information to better inform and risk-stratify patients prior to surgery., (©2021 by the author(s); Creative Commons Attribution License (CC BY).)

The peroneus quartus (PQ) muscle is a rare but sometimes missed potential etiology of ankle pain and tendon subluxation. We report the case of a 16-year-old boy who presented with lateral right ankle pain and subluxation of peroneal tendons. He had a history of non-Hodgkin lymphoma and palpable distal fibular osteochondroma. Seven months after excision of the exostosis and repair of the peroneal tendon retinaculum, the pain recurred. Imaging showed a split peroneus brevis (PB) tendon. During surgery, a PQ muscle was found and excised, and the PB tendon was repaired. One year after surgery, the patient's symptoms were resolved., Competing Interests: Authors’ Disclosure Statement: The authors report no actual or potential conflict of interest in relation to this article.

Background: C-reactive protein (CRP) has been suggested as an independent risk factor for cardiovascular pathology in the nonsurgical setting. While postoperative CRP and erythrocyte sedimentation rate (ESR) have an established role in aiding the diagnosis of periprosthetic joint infections, some authors suggest a link between preoperative CRP and postoperative complications in patients undergoing total joint arthroplasty., Methods: We conducted a retrospective cohort study of 351 patients who underwent unilateral primary total knee arthroplasty by a single surgeon during a 28-month period (January 2013 through April 2015). Patient medical records were reviewed for the following complications occurring within 90 days postoperatively: myocardial infarction, arrhythmia, pulmonary embolism, wound infection, acute renal failure, and reoperation., Results: We found no statistically significant link between postoperative complications and preoperative CRP levels ( P =0.5005) or ESR levels ( P =0.1610)., Conclusion: The results of this study do not support the routine inclusion of CRP and ESR analysis as part of the preoperative evaluation for elective total knee arthroplasty.

Background: Morton neuroma is a compressive neuropathy of the plantar digital nerve. Several surgical approaches have been used to treat painful Morton neuroma, with each approach having distinct advantages and disadvantages. For this study, we used validated outcome assessment tools to retrospectively compare patient satisfaction with 2 approaches., Methods: The medical records and survey responses of 37 patients with 42 neuromas were evaluated with respect to outcomes and patient satisfaction after neurectomies performed through either a plantar or dorsal surgical approach by one Ochsner Clinic Foundation attending physician. Outcomes were evaluated using the 36-Item Short Form Health Survey (SF-36) and the Foot Function Index (FFI) self-assessments., Results: Twenty patients underwent neurectomy through a dorsal approach, and 17 patients underwent neurectomy through a plantar approach. We found no statistically significant differences between the dorsal and plantar approach groups with respect to outcomes and patient satisfaction as measured by the SF-36 or the FFI., Conclusion: This study supports the use of either the plantar or dorsal approach for the resection of Morton neuroma and suggests that a plantar approach for neurectomy can produce satisfactory results.
