Anatomical and Micro-CT Assessment of the First Metatarsal Head Vascularization and Soft Tissue Envelope Following Minimally Invasive Chevron Osteotomy for Hallux Valgus Deformity.

Background: Minimally invasive surgical (MIS) chevron-type osteotomy for hallux valgus (HV) treatment offers a surgical alternative to open surgery with minimal surgical dissection and a hypothetical decreased risk for soft tissue complications. The objectives of this study were to assess the incidence of injuries to the soft tissue envelope and to the blood supply of the first metatarsal head through gross dissection and, using micro-computed tomography (micro-CT), to identify the safe position to perform the MIS chevron-type osteotomy of the first metatarsal head based on the anatomical data.

Methods: Twenty cadaveric specimens with HV were used for the study.

Lesser Metatarsophalangeal Joint Instability: Nonsurgical Treatment Alternatives.

Lesser metatarsophalangeal (MTP) joint instability can cause pain in the MTP joints with ambulation. The goal of nonsurgical treatment is to offload the metatarsal heads and stabilize the MTP joints. Achilles stretching can be effective by decreasing pressure in the forefoot with ambulation.

Early Outcomes Following Plantar Condylectomy and Imbrication of Plantar Plate to Metatarsal Neck for Metatarsalgia and Grade 0 Lesser Toe Metatarsophalangeal Joint Instability.

Background: Metatarsalgia and plantar plate tears are characterized by forefoot pain and toe deformity in severe cases. Conservative management may slow progression of symptoms; however, definitive treatment often requires operative intervention. The purpose of this observational study was to evaluate the combination of plantar condylectomy and surgical imbrication of the plantar plate to the metatarsal neck to repair grade 0 plantar plate injuries.

Comparison of Outcomes at Midterm Follow-up of Operatively and Nonoperatively Treated Isolated Weber B Ankle Fractures.

Objectives: A novel protocol was previously presented for nonoperative management of Weber B (OTA/AO 44B) ankle fractures with criteria of medial clear space <7 mm on gravity stress (GS) radiographs and ipsilateral superior clear space and contralateral GS medial clear space within 2 mm. This study recruited an operative cohort for comparison of outcomes.

Design: Retrospective cohort study.

Midterm Outcomes of Operatively and Nonoperatively Managed Achilles Tendon Ruptures in Young Adults.

Background: There continues to be controversy regarding treatment options for Achilles tendon ruptures (ATR). The aim of our study is to compare outcomes between operatively and nonoperatively managed Achilles ruptures in young adults (age 18-30 years), which has not been previously evaluated.

Methods: At a single institution, all patients aged 18-30 years at time of injury who underwent treatment for an acute ATR from 2014 to 2021 were evaluated.

Return to Sport After First Metatarsophalangeal Arthrodesis: A Systematic Review.

Background: First metatarsophalangeal (MTP) arthrodesis is a common surgical intervention for addressing MTP pain and deformity. Despite great interest on the topic of return to sport (RTS) after first MTP arthrodesis in the literature, no systematic review exists on this topic. The purpose of this systematic review is to investigate RTS after first MTP arthrodesis.

Learning curve associated with minimally invasive surgery for hallux valgus: A systematic review.

Background: The purpose of this systematic review is to examine the learning curve associated with minimally invasive surgery (MIS) for the treatment of hallux valgus (HV).

Methods: A systematic review was performed using PubMed, ScienceDirect, Web of Science, CINAHL and MEDLINE databases from database inception to February 16th, 2023. Inclusion criteria was articles with level of evidence I-III, any outcomes associated with learning curve, minimally invasive surgery, and diagnosis of hallux valgus' in adult patients.

Lateral Talar Subluxation Measurements in Nonoperatively Managed Weber B Ankle Fractures.

Background: Lateral talar subluxation (LTS) was introduced as a measurement tool for evaluating isolated Weber B ankle fractures, with LTS >4 mm on gravity stress (GS) radiographs possibly indicating need for surgery. This study reviews LTS measurements in nonoperatively managed isolated Weber B fibula fractures to further investigate the validity of this previously stated cutoff.

Methods: The senior authors previously reported outcomes of a novel algorithm for nonoperative management of isolated Weber B ankle fractures.

Surface Pressures in Lower Extremity Splints: A Biomechanical Study.

Background: Though ubiquitously used in orthopaedic trauma, lower extremity splints may have associated iatrogenic risk of morbidity. Although clinicians pad bony prominences to minimize skin pressure, the effect of joint position on skin pressure and, more specifically, changing joint position, is understudied. The purpose of this biomechanical study is to determine the effect of various short-leg splint application techniques on anterior ankle surface pressure in the development of iatrogenic skin pressure ulcers.

Proximal Plantar Plate of Lesser Toe Metatarsophalangeal Joint Vascular Supply.

Background: The plantar plate is a major stabilizing structure of the metatarsophalangeal (MTP) joint with instability frequently occurring after a tear or attenuation of this structure. Commonly, a McGlamry elevator is used to strip the plantar plate from the plantar surface of the metatarsal to improve exposure of the MTP joint. The anatomy of the proximal plantar plate and vascular consequence of stripping the plantar plate from the metatarsal is not yet well understood.

Medial Ankle Instability: Review of Anatomy, Evaluation, and Treatment.

The medial ankle ligamentous complex, which includes the deltoid, talocalcaneal, and calcaneonavicular ligaments, functions to provide stability to the medial ankle. Injuries to the deltoid ligament can lead to medial-sided ankle pain, subsequent instability, and posttraumatic osteoarthritis given the altered biomechanics of the ankle joint. After completing a thorough physical examination, imaging modalities such as stress radiographs and magnetic resonance imaging can be used to confirm the diagnosis.

Midterm Follow-up of a Novel Algorithm for Nonoperative Weber B Ankle Fractures.

Background: Stable Weber B ankle fractures are routinely treated nonoperatively. Our group previously presented a novel algorithm that provides radiographic parameters guiding when Weber B ankle fractures can be treated nonoperatively. The purpose of this study is to evaluate the durability of those results with a minimum 5-year follow-up.

Long-term Follow-up of Lisfranc Injuries Treated With Open Reduction Internal Fixation Patient-Reported Outcomes.

Background: There remains a paucity of data regarding long-term patient-reported outcomes following Lisfranc injuries. We sought to collect long-term clinical outcome data following Lisfranc injuries using PROMIS Physical Function (PROMIS-PF) and visual analog scale-foot and ankle (VAS-FA).

Methods: A chart review was performed to identify all patients who had surgical treatment of an acute Lisfranc injury at our institution from 2005 to 2014.

First Metatarsophalangeal Lateral Collateral Ligament Repair in an Athlete: A Case Report.

Case: Evidence-based surgical strategies to reconstruct the collateral ligament complex of the first metatarsophalangeal (MTP) joint are not available. We report a case of first MTP lateral collateral ligament insufficiency in a young, female gymnast with varus laxity and subsequent satisfactory mid-term and long-term outcomes.

Conclusion: This case report describes an efficient suture anchor technique for restoring stability of the first MTP joint because of chronic varus laxity with acceptable results both clinically and with patient-reported outcome scores at mid-term and long-term follow-ups.

Percutaneous Fixation of a Fifth Metatarsal Base Fracture.

Owing to a vascular watershed, zone II and III fifth metatarsal base fractures commonly progress to nonunion without operative intervention. This article and the accompanying video demonstrate the use of intramedullary screw fixation for a fifth metatarsal base fracture and review treatment decisions involved with management of these injuries.

Perioperative Management of Antirheumatic Medications in Patients with RA and SLE Undergoing Elective Foot and Ankle Surgery: A Critical Analysis Review.

»: Recent literature has shown that continued use rather than discontinuation of various antirheumatic agents throughout the perioperative period may present an opportunity to mitigate the risks of elective surgery.

»: For patients with rheumatoid arthritis and systemic lupus erythematosus, perioperative management of medication weighs the risk of infection against the risk of disease flare when immunosuppressive medications are withheld.

»: Broadly speaking, current evidence, although limited in quality, supports perioperative continuation of disease-modifying antirheumatic drugs, whereas biologic drugs should be withheld perioperatively, based on the dosing interval of the specific drug.

Presence of Neovascularization in Torn Plantar Plates of the Lesser Metatarsophalangeal Joints.

Background: Recent surgical techniques have focused on anatomic repair of lesser toe metatarsophalangeal (MTP) plantar plate tears, yet it remains unknown whether the plantar plate has the biological capacity to heal these repairs. Therefore, a better understanding of the plantar plate vasculature in response to injury may provide further insight into the potential for healing after anatomic plantar plate repair. Recently, a study demonstrated that the microvasculature of the normal plantar plate is densest at the proximal and distal attachments.

Ankle Arthrodesis Through an Anterior Approach.

Ankle arthritis occurs primarily because of trauma and has a huge impact on patient's quality of life. Ankle arthrodesis is indicated for patients with end-stage ankle arthritis who fail conservative management. High rates of fusion can be achieved through an anterior approach.

Evaluation of Heat Generation in Unidirectional Versus Oscillatory Modes During K-Wire Insertion in Bone.

Heat generation during insertion of Kirschner wires (K-wires) may lead to thermal osteonecrosis and can affect the construct fixation. Unidirectional and oscillatory drilling modes are options for K-wire insertion, but understanding of the difference in heat generation between the two modes is lacking. The goal of this study was to compare the temperature rise during K-wire insertion under these two modes and provide technical guidelines for K-wire placement to minimize thermal injury.

New Persistent Opioid Use Following Common Forefoot Procedures for the Treatment of Hallux Valgus.

Background: Orthopaedic surgeons are the fourth highest on the list of top prescribers of opioid analgesics by specialty and have a direct impact on opioid-related morbidity in the United States. Operative bunion correction is one of the most commonly performed elective foot surgical procedures in this country. We sought to determine the rate of new persistent opioid use following exposure to opioids after surgical treatment of hallux valgus (bunionectomy) and to identify associated risk factors.

Initial Displacement Does Not Affect Loss of Reduction After Lisfranc Fracture Dislocations.

We sought to determine whether significantly displaced Lisfranc injuries had a higher rate of loss of reduction after fixation compared to those with low displacement. Forty-five patients who had fixation of an acute Lisfranc injury from 2005 to 2014 were retrospectively reviewed. All patients underwent subsequent hardware removal at 3 to 15 months after their index procedure.
