Congenital Vertical Talus: An Updated Review.

Congenital vertical talus (CVT) is the presence of rigid flatfoot deformity characterized by hindfoot valgus and equinus. This foot deformity is associated with midfoot dorsiflexion and forefoot abduction due to a fixed dorsal dislocation of the navicular relative to the head of the talus. It is often underdiagnosed in children due to its similarity to other disorders of the foot. Misdiagnosis of CVT and subsequent failure to address it leads to significant disability and pain. While past surgical management consisted of soft tissue releases that produced varying efficacy, current management of CVT consists of serial casting and minimally invasive procedures that have yielded excellent long-term outcomes. This review provides insight into the diagnosis and treatment of CVT with the intention of highlighting the importance of promptness of intervention to prevent further disability.

Intraoperative Intra-articular Antibiotic Injection Reduces Infection in Shoulder Arthroplasty.

Deep infection is a debilitating complication after shoulder arthroplasty. The authors hypothesized that an intra-articular, intraoperative injection of antibiotics would result in a lower infection rate compared with intravenous antibiotics alone. Before 2007, 164 patients (group A) did not receive intra-articular antibiotics. From 2007 to 2018, 1324 patients (group B) received intra-articular antibiotics. Patients received intra-articular gentamicin at the end of surgery with the addition of 1 g of cefazolin in January 2014. Records were retrospectively reviewed for comorbidities, type of surgery, and infection. The cohort that received intra-articular antibiotics was compared with the cohort that did not to determine the effect of prophylactic intra-articular antibiotic administration in preventing infection. There was 1 deep infection in the antibiotic group compared with 5 in the non-antibiotic group (P<.001). Superficial infections developed in 2 cases of patients treated with antibiotics; there were no superficial infections in patients treated without antibiotics (P=.62). One previous study evaluated intra-articular injection of antibiotics for shoulder arthroplasty and found significantly lower rates of infection with the injection of intra-articular gentamicin. In this retrospective follow-up study, the injection of intra-articular gentamicin or gentamicin and cefazolin effectively decreased rates of postoperative infection. At mean follow-up of 399 days, intra-articular antibiotics at the time of surgery resulted in significantly fewer deep infections. Given the minimal risk of adverse events and minimal cost, this is a valid method of reducing infections in total shoulder arthroplasty. [Orthopedics. 2023;46(5):310-314.].

Under Disclosure of Conflicts of Interest Is Less Frequent in Senior Authors: A Cross-sectional Review of All Authors Submitting to JAAOS Between 2014 and 2018.

The interactions between physicians and industry are necessary for advancement of clinical practice and improvement in medical devices. Physician-industry relationships also introduces financial conflicts of interest into research publications. Payments to physicians do not inherently introduce bias in research, but failure to disclose potential conflicts of interest can negatively impact the perceived integrity of authors, editors, and journals. The conflict of interest disclosure statement in all articles published in the Journal of the American Academy of Orthopaedic Surgery between 2014 and 2018 were compared to the financial payments indexed in the Center for Open Payments Database. Payment type, magnitude, and payer were obtained for each payment meeting inclusion criteria. Statistical comparisons were made using Mann-Whitney comparisons due to non-normal distribution of payment amounts. 704 articles involving 2596 authors were reviewed, with 1268 authors meeting inclusion criteria. 634 authors had accurate disclosure statements. The total amount of disclosed payments was $169 million, whereas undisclosed payments were $14.2 million. The amount of disclosed payments on a per-author basis, $55,844 ($12,559, $186,129), was significantly greater than undisclosed payments, $2,171 ($568, $7,238). The lowest rates of correct disclosure were in education (29.2%), gifts (38.7%) and honoraria (57.8%). First and middle authors disclosed correctly at a significantly lower rate than last authors. The magnitude of undisclosed payments was significantly lower than disclosed payments, indicating that these payments do not register with authors as significant enough to disclose.

Incidence of Nerve Injury After Hip Arthroscopy.

INTRODUCTION: Hip arthroscopy is a commonly performed procedure that carries a notable risk of nerve injury secondary to port placement and the use of axial traction. Sensory neurapraxia of the pudendal nerve and the lateral femoral cutaneous nerve is most common; however, sexual dysfunction and sciatic nerve injury has also been reported. Reported incidence of nerve injury ranges between 1.4% and 5% in the literature, but much of these data are based on unsolicited patient concerns. This study aimed to determine the true rate of nerve injury among this patient population through administration of a validated survey at multiple time points. METHODS: A prospective study of all patients undergoing hip arthroscopy requiring traction by a single surgeon at our institution was performed. These cases were the first 100 hip arthroscopies performed in practice by the surgeon. Before surgery, all patients were asked about the presence of neuropathic symptoms including sexual dysfunction through administration of a validated questionnaire. The same questionnaire was then administered at several time points postoperatively: on the day of surgery, on postoperative day 2, at the first follow-up visit, and if symptoms persisted, then at each follow-up appointment until resolution of the symptoms. Overall incidence of nerve injury was then calculated. Subgroup analyses were performed to investigate whether traction time, sex, body mass index (BMI), or technically demanding surgical skills affected the incidence. RESULTS: This study included a total of 100 patients with an average age of 29 (13 to 62) years and an average BMI of 25. Nerve injury was seen in 13 patients with an incidence of 13%. Specific nerves injured included the pudendal (9), lateral femoral cutaneous (2), sciatic (1), and superficial peroneal nerves (1). Subgroup analysis did not demonstrate a notable association between the risk of nerve injury and increased traction time, sex, or increased BMI. The technically demanding surgical skills was associated with a notable decrease in the traction time, but no notable difference in the risk of nerve injury was observed. Most nerve injuries resolved within 2 weeks (8 of 13), and all cases of nerve injury resolved within 9 months. DISCUSSION AND CONCLUSIONS: The incidence of nerve injury after hip arthroscopy may be markedly higher than previously reported; however, resolution seems to occur as previously found in the literature. Patients should be educated regarding the risk of nerve injury during this procedure. LEVEL OF EVIDENCE: Level IV.

Total knee arthroplasty and fractures of the tibial plateau.

Tibial plateau fractures are common injuries that occur in a bimodal age distribution. While there are various treatment options for displaced tibial plateau fractures, the standard of care is open reduction and internal fixation (ORIF). In physiologically young patients with higher demand and better bone quality, ORIF is the preferred method of treating these fractures. However, future total knee arthroplasty (TKA) is a consideration in these patients as post-traumatic osteoarthritis is a common long-term complication of tibial plateau fractures. In older, lower demand patients, ORIF is potentially less favorable for a variety of reasons, namely fixation failure and the need for delayed weight bearing. In some of these patients, TKA can be considered as primary mode of treatment. This paper will review the literature surrounding TKA as both primary treatment and as a salvage measure in patients with fractures of the tibial plateau. The outcomes, complications, techniques and surgical challenges are also discussed.
