Treatment of Charcot neuroarthropathy (CN) of the foot and ankle remains challenging for both patients and surgeons. Nonoperative treatment with cast/orthosis immobilization has long been the main treatment, but surgical intervention has gained interest to improve poor long-term outcomes. Few long-term outcome studies exist on operative management of CN.

Treatment of Charcot neuroarthropathy (CN) of the foot and ankle remains challenging for both patients and surgeons. Nonoperative treatment with cast/orthosis immobilization has long been the mainstay of treatment, but surgical intervention has gained interest to improve poor long-term outcomes. A review of existing data on the operative management of CN demonstrates the potential benefits but also the continued risks associated with treatment.

Background: Exposure to a comprehensive breadth and volume of surgical cases is a fundamental component of orthopaedic education, though standardization of case exposures across residency programs is limited to a small amount of required case minimums. Significant variability in exposure to subspecialty cases, such as foot and ankle surgeries, can create distinctly different residency experiences.

Methods: Accreditation Council for Graduate Medical Education (ACGME) surgical case logs from 2014 to 2019 for leg/ankle and foot/toes were examined following the 2013 implementation of case minimums.

Penicillin allergies are reported by 8% to 15% of the US population, but up to 95% of these allergies do not correspond to a true allergy when tested. Recent studies have demonstrated that having a penicillin allergy label (PAL) results in a 50% increased odds of surgical site infection among patients reporting a penicillin allergy entirely attributable to the use of a beta-lactam alternative antibiotic (primarily clindamycin or vancomycin). This study provides a review of the prevalence of PAL, the cross-reactivity with cefazolin, immunogenic components of cefazolin and penicillin, and current guidelines for preoperative antibiotic selection in patients with PALs.

The limited natural capacity for articular cartilage to regenerate has led to a continuously broadening array of surgical interventions. Used once patients' symptoms are not relieved by nonoperative management, these share the goals of joint preservation and restoration. Techniques include bone marrow stimulation, whole-tissue transplantation, and cell-based strategies, each with its own variations.

We conducted a study to determine the general level of knowledge that orthopedic residents have on business and practice management topics at graduation and to evaluate the level of knowledge that practicing orthopedic surgeons need in order to function effectively in a medical practice. Residency graduates from a single training program were asked to complete a survey that gathered demographic information and had surgeons rate their understanding of 9 general business and practice management skills and the importance of these skills in their current practice situation. The amount of necessary business knowledge they lacked at graduation was defined as a functional knowledge deficiency (FKD) and was calculated as the difference between the reported importance of a topic in current practice and the level of understanding of that topic at graduation (larger FKD indicates greater deficiency).

Interdigital neuromas are a common cause of forefoot pain, and approximately 80% of patients require surgical excision for symptom relief. Although 50% to 85% of patients obtain relief after primary excision, symptoms may recur because of an incorrect diagnosis, inadequate resection, or adherence of pressure on a nerve stump neuroma. The symptom relief rate after reoperation is similar to that after primary excision.

Objective: Because of the importance of current procedural terminology (CPT) coding in both resident education evaluation and practice management, this study was undertaken to evaluate the correlation and interrater reliability between residents and attending physicians in CPT coding for orthopedic foot and ankle surgeries as well as to determine attending surgeons' and residents' familiarity with and confidence in the coding process.

Methods: CPT codes from resident case logs were compared with those submitted by attending surgeons, and Pearson's correlation coefficient and interrater reliability were calculated to examine coding congruency. An online survey was also used to examine attending surgeon and resident perceptions and habits regarding CPT codes and the coding process.

Critical review of the available evidence indicates that a relationship exists between sufficient vitamin D status and stress fractures, although genetic and environmental factors are involved as well. Patients at high risk for stress fracture should be educated on protective training techniques and the potential benefits of supplementation with combined calcium and vitamin D, particularly if increased exercise is planned during winter or spring months, when vitamin D stores are at their lowest. The amount of vitamin D intake required is highly variable depending on many factors including sun exposure, and therefore many recommendations have been made for daily vitamin D intake requirements.

Background: Achilles tendinosis and chronic Achilles tendon ruptures are relatively frequently encountered by orthopaedic surgeons. One treatment for patients who fail to respond to conservative management involves augmentation of the repair with transfer of the flexor hallucis longus (FHL), using either a single-incision or double-incision technique. Despite the frequency of this procedure, little is known about the associated donor morbidity.
