Normative contact mechanics of the ankle Joint: Quantitative assessment utilizing bilateral weightbearing CT.

Alterations in ankle's articular contact mechanics serve as one of the fundamental causes of significant pathology. Nevertheless, computationally intensive algorithms and lack of bilateral weightbearing imaging have rendered it difficult to investigate the normative articular contact stress and side-to-side differences. The aims of our study were two-fold: 1) to determine and quantify the presence of side-to-side contact differences in healthy ankles and 2) to establish normative ranges for articular ankle contact parameters.

Use of Bio-integrative Screws for Fixation of Lisfranc Instability; Pros and Cons from Surgeons' Point of View in a Cadaver Study.

Comparison between achilles tendon reinsertion and dorsal closing wedge calcaneal osteotomy for the treatment of insertional achilles tendinopathy: A meta-analysis.

Background: The debridement and Achilles tendon reinsertion (DATR) have been the most common surgical approach for the treatment of Insertional Achilles Tendinopathy (IAT), while dorsal closing wedge calcaneal osteotomy (DCWCO) has recently gained popularity as an alternative surgical option. This study aimed to systematically review the published literature on both surgical techniques and compare their clinical outcomes and complication rates.

Methods: A systematic review was performed according to the PRISMA guidelines using Medline, Embase, and Scopus databases.

Disparity in sex in ankle fracture treatment.

Background: Literature has shown implicit bias in the treatment between non-operative and surgical treatment in patients with certain types of ankle fractures, which comprise 7.6% of all adult fractures. An understanding of any bias across all ankle fracture management may prove to be critical for the understanding of potential correlations between treatment methods and outcomes of patients with ankle fractures.

Talonavicular Osteochondral Lesions: Surgical Technique and Clinical Outcomes from the Boston and Amsterdam Perspectives.

Purpose: The primary purpose of the present study was to assess the patient-reported outcomes, complications, and reoperation rate of patient who underwent surgical treatment for symptomatic osteochondral lesions of the talonavicular joint (TNJ).

Methods: Patients undergoing surgical treatment for symptomatic osteochondral lesions of the TNJ with a minimum of 12-month follow-up were included. Outcomes included clinical patient-reported outcome measures (PROMs), return to sports and work outcomes, and postoperative complications or reoperations.

Intermetatarsal ligament section assisted with sonography for the percutaneous surgery of Morton's disease: Cadaveric study.

Background: Surgical treatment of Morton's neuroma remains controversial. Several surgical techniques have been described including percutaneous transection of the deep metatarsal transverse ligament (DMTL).

Purpose: To evaluate the efficacy and safety of percutaneous release of the DMTL under ultrasound guidance for the treatment of Morton's syndrome.

Average 4-Year Outcomes of Distal Oblique First Metatarsal Osteotomy for Stage 1 to 3 Hallux Rigidus.

Background: Hallux rigidus is the second most frequent pathology of the first ray. Surgical options for degenerative metatarsophalangeal joint disease are either joint destructive or conservative procedures. The hypothesis was that oblique distal shortening osteotomy of the first metatarsal is an effective conservative technique for the management of stage 1 to 3 hallux rigidus.

The Syndesmosis, Part II: Surgical Treatment Strategies.

Syndesmotic injuries in the setting of ankle fracture are critically important to diagnosis and treat to restore an anatomic tibiotalar relationship. Physical examination and clinical suspicion remain critically important for diagnosis. Ultrasound examination and weight-bearing computed tomography scans are evolving to help diagnosis more subtle injuries.

The Syndesmosis, Part I: Anatomy, Injury Mechanism, Classification, and Diagnosis.

Ankle fractures are common injuries to the lower extremity with approximately 20% sustaining a concomitant injury to the syndesmosis. Although the deltoid ligament is not formally included in the syndesmotic complex, it plays an important role in the mortise stability. Therefore, its integrity should be always evaluated when syndesmotic injury is suspected.

Diagnosis and Treatment of Syndesmotic Unstable Injuries: Where We Are Now and Where We Are Headed.

Up to 10% of ankle sprains are considered "high ankle" sprains with associated syndesmotic injury. Initial diagnosis of syndesmotic injury is based on physical examination, but further evaluation of the distal tibiofibular joint in the sagittal, coronal, and rotational planes is necessary to determine instability. Imaging modalities including weight-bearing CT and ultrasonography allow a physiologic and dynamic assessment of the syndesmosis.

Return to Play After Revision Anterior Shoulder Stabilization: A Systematic Review.

Background: Revision shoulder stabilizations are becoming increasingly common. Returning to play after revision shoulder stabilizations is important to patients.

Purpose: To evaluate the return-to-play rate after revision anterior shoulder stabilization using arthroscopic, open, coracoid transfer, or free bone block procedures.

Combined Total Talus Replacement and Total Ankle Arthroplasty.

Avascular necrosis (AVN) of the talus remains a clinical challenge with suboptimal outcomes after treatment. In cases of extensive disease, the insufficient blood supply leads to a high rate of complications including non-union after surgical treatment. This, in conjunction with the development of premature adjacent arthritis represents a challenge for the treating surgeon.

Prevalence of Hallux Rigidus in Patients With End-Stage Ankle Arthritis.

Arthritis of the foot is a significant cause of pain and disability. The prevalence of foot arthritis in adults aged ≥50 has been reported to be 17%. Of those, 25% are estimated to be radiographic arthritis of the first metatarsophalangeal joint.

Biomechanical Effect on Joint Stability of Including Deltoid Ligament Repair in an Ankle Fracture Soft Tissue Injury Model With Deltoid and Syndesmotic Disruption.

Background: The current operative standard of treatment for bimalleolar equivalent ankle fracture is open reduction and internal fixation (ORIF) of the lateral malleolus followed by syndesmotic stabilization if indicated. There is controversy surrounding the indication and need for deltoid ligament repair in this setting. The purpose of this study was to quantify the biomechanical effect of deltoid ligament repair in an ankle fracture soft tissue injury model.

Outcomes After Revision Anterior Shoulder Stabilization: A Systematic Review.
