Sonographically guided therapeutic injections in the meniscoid lesion in patients with anteromedial ankle impingement syndrome.
We describe a sonographically guided technique to perform therapeutic injections for anteromedial ankle impingement syndrome. Scans are carried out using a high-frequency small footprint linear array transducer, positioned along the anteromedial aspect of the tibiotalar joint. A 25 gauge needle is advanced under direct sonographic guidance into the "meniscoid lesion" (area of scarring), and a standardized therapeutic mixture is injected extra-articularly. Image-guided injections have a positive influence on clinical decision making by improving patient management, increasing the accuracy of diagnosis, and decreasing patient pain. Sonography allows confirmation of correct injection placement, resulting in increased accuracy and more successful patient outcomes. ⋯ Therapeutic, Level V, Expert Opinion.

Case ReportsOpen fracture dislocation of the talus with total extrusion: a case report.
Open fractures with complete extrusion of talus are high-energy injuries. While treating these injuries, union of the fracture, vascularity of the body, and possibility of infection are main issues predicting less favorable outcomes. At present, there are no recommended treatment protocols for the management of such injuries. Early debridement, wound care, anatomic reduction, and adequate fixation are key factors in the management of compound injuries of the talus. There are few reports in the literature on successful reimplantation of talus when it is completely extruded. Encouraging functional outcomes of reimplantation of extruded talus suggest that excision of the talus with or without tibiocalcaneal fusion should be kept as a salvage procedure. We report a case of a farmer who sustained fracture of the talar neck. Both head and body fragments were completely extruded from the wound on the anterolateral aspect of the ankle. The patient was treated 18 hours postinjury. Thorough debridement of wound and bony fragments was done. Talus was reimplanted and fixation was performed with Kirschner wires. At 3-year follow-up, satisfactory functional outcome was noted with AOFAS (American Orthopaedic Foot and Ankle Society) score of 83 and MOXFQ (Manchester-Oxford Foot Questionnaire) scale score of 23. The purpose of presenting this case is to demonstrate the successful outcome of reimplantation of talus. ⋯ Therapeutic, Level IV: Case study.

Missed peritalar injuries: an analysis of factors in cases of known delayed diagnosis and methods for improving identification.
Because of the complex anatomy of the foot, rarity of fractures of the foot, and subtle radiographic cues, foot injuries are commonly overlooked and mis/undiagnosed. This study seeks to investigate a patient population whose peritalar injuries, including fractures and dislocations, were missed on initial examination, in order to analyze factors of known, missed injuries and provide insight into methods for reducing the incidence of missed diagnoses. Surgical cases between January 1999 and May 2011 were queried and retrospectively reviewed to identify missed peritalar injuries. Of 1682 surgical cases reviewed, 27 patients with missed peritalar injury(ies), which were subsequently confirmed by imaging studies, were identified. Using the Orthopaedic Trauma Association classification, fracture and dislocation subtypes were classified. A medical record review was performed to assess demographic and surgical data elements. In this study population, 7 types of peritalar injuries (talus, calcaneal, navicular, and cuboid fractures as well as subtalar, calcaneocuboid, and talonavicular joint dislocations) were diagnosed in 27 patients. All patients required surgical intervention. Talus fractures were the most commonly missed injury. In patients with multiple peritalar injuries, there was a strong correlation between talus and navicular fractures (r = -0.60; P < .01) as well as a moderate correlation between talus fractures and calcaneocuboid dislocations (r = -0.46; P = .02). The presence of a calcaneal fracture significantly decreased the time to definitive diagnosis (P = .01). Male patients' diagnoses were delayed an average of 324 days and females 105 days (P = .04). A moderate correlation was found between patient age at injury and time to diagnosis (r = -0.47; P = .04), with a decreased time to diagnosis as patient age increased. Significant factors were identified in this patient population, including patient sex and age, which may contribute to missed or delayed diagnosis in the clinical setting. Prompt and accurate diagnosis of peritalar injuries may improve long-term outcomes. ⋯ Care Management, Level V.

Simultaneous first metatarsophalangeal joint arthrodesis and sesamoidectomy with a single dorsomedial incision.
First metatarsophalangeal (MTP) arthrodesis is a well-accepted procedure for the treatment of end-stage hallux rigidus. Despite the excellent and predictable clinical results, the procedure does not address the metatarso-sesamoid joint complex. There has been one case report of arthritis of the metatarsal sesamoid joint as uncommon cause of post-arthrodesis hallux pain. Additionally, we have noted this complication in our practice as well despite the paucity of reported cases in the published literature. Resection of either the tibial or fibular sesamoid is an acceptable treatment for recalcitrant sesamoid pain; however, resection of both the tibial and fibular sesamoids as would be required for arthritic changes is not encouraged to prevent the risk of a cock-up toe deformity. Arthrodesis of the first MTP joint eliminates the possibility of this complication. Resection of the sesamoids following a first MTP fusion requires a separate incision with additional morbidity and risk to the medial plantar digital nerve. This second surgical intervention is not without morbidity and carries additional cast to the patient, which can be avoided if the pathology is appropriately identified preoperatively. We describe the surgical indications and novel technique for a first MTP arthrodesis and total sesamoid resection through a standard dorsomedial incision. The approach adds minimal surgical time and morbidity and eliminates the source of plantar first MTP pain that is present in a cohort of patients with hallux rigidus. ⋯ Level IV, Case Series.
