Anatomical Structures at Risk in Percutaneous Distal Bunionette Correction.

Bunionette deformity is an incredibly pervasive issue in our society with almost a quarter of individuals being affected by it. As it is so common, there are numerous techniques and approaches to correct the deformity. Currently, there is a growing trend that favors percutaneous osteotomy of the bunionette. As there are multiple osteotomy sites, there are anatomical considerations that must be made at each one. The purpose of this study was to investigate the anatomic structures at risk during distal osteotomy of bunionette deformity using a Shannon burr. Using 11 fresh cadaver specimens, the fifth metatarsal was accessed through a carefully marked portal. A Shannon burr was employed for the osteotomy. Dissections were performed to assess potential damage to critical structures, including the lateral dorsal cutaneous nerve (LDCN), abductor digiti minimi (ADM), and extensor digitorum longus (EDL). Measurements were taken from the osteotomy site to each structure. The distal osteotomy site was on average greater than 8 mm from the EDL and ADM, whereas it was 1.64 mm from the LDCN. The Shannon burr made contact with and transected the LDCN on 2 occasions. However, previous studies have highlighted potential anatomical variations of the LDCN that arise distally. The study underscored the challenges posed by minimally invasive approaches to treating bunionette deformity and highlighted the need for cautious consideration when using percutaneous methods.Level of Clinical Evidence: 5.

Evolution in Casting Techniques: A Narrative Review of Casting Methods, Techniques, and Innovation.

Orthopedic casting has seen a remarkable evolution from ancient practices to cutting-edge innovations. Beginning with ancient Egyptian methods employing bark, linen, and bandages, casting techniques have progressed through historical milestones, including the adoption of plaster of Paris in the 19th century and the introduction of synthetic materials like fiberglass and thermoplastics in the 20th century. Historical progressions transitioned from primitive materials to more sophisticated techniques, such as resin-soaked bandages and starch-based casts. While thermoplastics showcased benefits like adjustability and comfort, widespread adoption faced hurdles due to cost and water resistance limitations. The emergence of 3D printing introduced patient-specific casts with improved ventilation but faced challenges in accessibility, cost, and immediate immobilization. FlexiOH presents as a groundbreaking foam cast by Orthoheal, offering customizable fit, lightweight design, improved ventilation, and moisture resistance. Its potential to reduce ER visits, enhance patient comfort, and streamline application procedures positions it as a promising technology for the future. This paper discusses each casting generation's advantages and drawbacks, highlighting the potential of innovative technologies like FlexiOH to revolutionize orthopedic casting practices, promising improved outcomes, reduced costs, and enhanced efficiency.

Utility of Follow-up Radiographs in Type 1 Supracondylar Humerus Fractures.

OBJECTIVE: Supracondylar humerus (SCH) fractures are common among pediatric patients, with the severity categorized using the Gartland classification system. Type 1 SCH fractures are nondisplaced and treated with immobilization, while more displaced fractures require surgery. The need for follow-up radiographs, particularly for type 1 fractures, is an area where evidence is lacking. This study investigates the clinical value and financial implications of follow-up radiographs for type 1 SCH fractures, hypothesizing that they do not alter clinical management and, therefore, represent an unnecessary expense. METHODS: This retrospective cohort study, approved by the Institutional Review Board, focused on patients under 18 with nondisplaced SCH fractures treated nonoperatively. One hundred one type 1 SCH fractures, in which the fracture was visible on presenting radiographs, were chosen from patients presenting between January 2021 and December 2022. Charts were reviewed for demographic information, time of cast removal, and complications. A pediatric orthopaedic surgeon and orthopaedic resident reviewed the radiographs to confirm the injury to be a type 1 SCH fracture. RESULTS: Among the 101 patients, after the initial presentation, 79 attended an interim visit and 101 attended a "3-week follow-up" at an average of 23 days postinjury. All patients underwent radiographs during these visits for a total of 180 radiographs after confirmation of type 1 SCH fracture. No changes in management resulted from follow-up radiographs. One instance of refracture was noted ~3 months after cast removal. There were 180 superfluous follow-up radiographs taken at subsequent clinic visits. The total charge for these radiographs was $76,001.40, averaging $752.49 per patient. CONCLUSION: Follow-up radiographs for type 1 SCH fractures did not lead to changes in clinical management, aligning with previous findings in more severe SCH fractures. This approach can reduce costs, radiation exposure, and clinic time without compromising patient care. The study can reassure providers and parents about the lack of necessity for follow-up radiographs to document healing. LEVEL OF EVIDENCE: Level-IV.

Anatomical Structures at Risk in Percutaneous Preparation Talonavicular Fusion.

BACKGROUND: The stability of the hindfoot greatly relies on the integrity of the talonavicular joint. Pathologies affecting this joint often necessitate fusion. Our study explores the risks posed to neurovascular and tendon structures during simulated percutaneous talonavicular joint preparation for fusion. METHODS: In 9 fresh cadaver specimens, the talonavicular joint was accessed through two portals. A 2-mm Shannon burr was employed for joint surface preparation with distraction provided by a pin-based distractor. Dissections were performed to assess potential damage to critical structures, including the dorsalis pedis artery, superficial and deep peroneal nerves, extensor hallucis longus (EHL), and tibialis anterior (TA) tendons. RESULTS: The dorsal portal site was found to be significantly closer to important structures compared to the medial portal site. The Shannon burr made contact with various structures, with a single transection identified for both deep and superficial peroneal nerve branches. During the dorsal portal site approach, potential injury to the EHL tendon was identified as concern. CONCLUSION: This study sheds light on the potential risks associated with percutaneous dorsal and medial joint preparation approaches using a Shannon burr.Level of Evidence:Level V, mechanism-based reasoning..
