Anatomy, Biomechanics, and Pathogenesis of the Lesser Toes Deformities.

Deformities of the lesser toes are a prevalent condition faced by orthopedic surgeons. An imbalance between the extensor and flexor muscles might cause these deformities, affecting the metatarsophalangeal joint (MTPJ) and interphalangeal joint (IPJ). Therefore, a thorough understanding of the anatomy, biomechanics of the MTPJ, the surrounding structures, and the pathogenesis of lesser toe deformities is crucial for ensuring the correct diagnosis and treatment of the deformities.

A Radiologic Triangle Sign for Percutaneous Adductor Tendon Release (PATR): Cadaveric Study and Case Series.

Background: Combining osteotomies and soft tissue procedures is believed to reduce sesamoids in their anatomical position and maintain long-term correction when treating hallux valgus deformity. This study determines if a radiologic association exists between a radiolucent sign and a full percutaneous adductor tendon release (PATR), including a cadaveric study and a consecutive case series. Another aim was to determine the intra- and interobserver reliability of these observations.

Treatment of hallux rigidus with percutaneous metatarsophalangeal arthrodesis: a case series with a minimum follow-up of 2 years.

Background: Percutaneous metatarsophalangeal arthrodesis is an option for the treatment of hallux rigidus in more advanced cases. The aim of this study was to investigate the clinical and radiographic results at least 2 years after percutaneous metatarsophalangeal arthrodesis in patients with hallux rigidus.

Methods: This is a case series of consecutive patients undergoing percutaneous metatarsophalangeal arthrodesis in patients with hallux rigidus grades III and IV with a minimum of 24 months of clinical and radiographic follow-up.

Intra‑ and Interobserver Reliability of Yamaguchi's Method for the Assessment of First Metatarsal Pronation in Hallux Valgus Deformity.

Pronation of the first metatarsal is a risk factor for the formation and progression of the hallux valgus deformity. Recently, Yamaguchi et al published a study that showed how the round sign increases on digitally reconstructed radiography taken from a CT scan when pronation is applied. In this study, the shape of the lateral edge of the first metatarsal head was evaluated on weightbearing dorsoplantar radiographs.

Midterm Outcomes of Sliding Distal Metatarsal Minimally Invasive Osteotomy to Treat Bunionette Deformity.

Background: Bunionette deformity is described as a painful bony prominence on the lateral aspect of the fifth metatarsal head. The present study prospectively assessed the clinical, functional, and radiographic outcomes of sliding distal metatarsal minimally invasive osteotomy (S-DMMO) used in a large series of patients with a midterm follow-up period.

Methods: From December 2015 to December 2018, we evaluated 74 feet (57 patients).

Modified Bösch Osteotomy Combined With a Percutaneous Adductor Tendon Release for the Treatment of Hallux Valgus Deformity: Learning Curve.

Purpose: The expression "learning curve" indicates the relation between the time needed to learn a new technique and the technique-related outcome. Percutaneous surgery (also called "minimally invasive surgery") has experienced sustained and respectable growth, especially in forefoot deformities. The main purpose was to assess the number of feet necessary to become skilled in a specific minimally invasive surgery (MIS) procedure.

osteomyelitis of the calcaneus: Case report and literature review.

is an encapsulated, yeast-like fungus that can cause a systemic mycosis, particularly in immunocompromised patients. Disseminated infections typically affect the central nervous system, and osseous lesions are infrequent. Only 5%-10% of disseminated cryptococcosis involves bones.

Percutaneous, intra-articular, chevron osteotomy (PeICO) for the treatment of mild-to-moderate hallux valgus: a case series.

Purpose: Treatment for hallux valgus (HV) remains challenging. Third-generation percutaneous procedures try to reproduce chevron-type osteotomies to replicate their benefits, such as intrinsic stability and reproducibility. We report the first results using a percutaneous, intra-articular, chevron osteotomy (PeICO) technique that mimics the classic intra-articular open chevron procedure, associated with a percutaneous adductor tendon release (PATR) for the treatment of mild-to-moderate HV.

Correction Power of Percutaneous Adductor Tendon Release (PATR) for the Treatment of Hallux Valgus: A Cadaveric Study.

Osteotomies are commonly used in order to correct hallux valgus deformity. However, soft tissue structures also play an essential role in the etiology, progression, and treatment of hallux valgus (HV). The purpose of the present study was to analyze the correcting power (varus), reduction strength (sesamoid) and rotation of metatarsal and proximal phalanx after percutaneous adductor tendon release (PATR).

Percutaneous Lateral Release in Hallux Valgus: Anatomic Basis and Indications.

In the last decade, minimally invasive or percutaneous surgery has evolved rapidly through the development of novel techniques. Treatment of hallux valgus deformity is one of the indications for percutaneous surgery, both for bony and soft tissue correction. The release of the structures on the lateral part of the first metatarsophalangeal joint (lateral release) is one of the best indications for percutaneous surgery in the forefoot.

Comparison of two forced-air warming devices during foot and ankle surgery: a randomised controlled trial.

Inadvertent perioperative hypothermia is a frequent problem associated with surgical patients which can have significant consequences during surgery and in the immediate postoperative period. We compared 35 randomised patients using over vs. under body forced air heating.

Patient-specific three-dimensional printed hemi talar prostheses for the treatment of talar osteonecrosis, case report and literature review.

We present the case of a 43-year-old boy who presented with progressive pain as a result of history of lateral avascular necrosis of the talus secondary to traumatic open ankle luxation 20 years ago. Conservative treatment (12-month period) prior to surgery failed. It consisted of physiokinetic treatment, insoles and analgesic medication.

Endoscopic Flexor Hallucis Longus Transfer for the Management of Acute Achilles Tendon Ruptures: A Prospective Case Series Report With a Minimum of 18 Months' Follow-Up.

Acute Achilles tendon rupture can be treated either surgically or nonsurgically. The flexor hallucis longus (FHL) has been used successfully in patients with large chronic Achilles tendon defects. The aim of this study was to describe the clinical outcomes of isolated endoscopic FHL transfer in patients with acute Achilles tendon ruptures at a minimum follow-up of 18 months.

Anatomical Study of Minimally Invasive Lateral Release Techniques for Hallux Valgus Treatment.

Background: Lateral release (LR) for the treatment of hallux valgus is a routinely performed technique, either by means of open or minimally invasive (MI) surgery. Despite this, there is no available evidence of the efficacy and safety of MI lateral release. Our aim was to study 2 popular techniques for MI LR in cadavers by subsequently dissecting the released anatomical structures.

Evolution of Minimally Invasive Surgery in Hallux Valgus.

Minimally invasive (MIS) or percutaneous surgery has evolved rapidly through the development of novel techniques with precise description, correct indications, and the incorporation of modifications of safe and effective techniques described in open surgery. The correct term to describe these procedures should be percutaneous and MIS should be reserved for procedures between percutaneous and open surgery (eg, osteosynthesis). According to results, third-generation techniques are useful, effective, and easier than open procedures.

Percutaneous, Intra-articular, Chevron Osteotomy (PeICO) for the Treatment of Hallux Valgus: A Cadaveric Study.

Background: Percutaneous surgery is experiencing sustained growth based on third-generation techniques. This cadaveric study was designed with the main goal of exploring the risk of iatrogenic tendon and neurovascular lesions and defining the safe zones in a percutaneous, intra-articular, chevron osteotomy (PeICO) procedure, as well as assessing the accuracy of the osteotomy itself.

Methods: Eight feet from below-knee fresh-frozen specimens were selected.

Osteochondral Lesions of the Talus Treatment With Fresh Frozen Allograft.

Introduction: Symptomatic talar osteochondral lesions are about 50% refractory to conservative treatment requiring a surgical solution. In the case of large chronic lesions, the use of bone graft taken from tissue bank is an alternative that enables to fill the defect without causing donor site morbidity.

Material And Methods: Eight patients treated with talar osteochondral allograft in lesions greater than 20mm in diameter were analyzed - 4 males and 4 females aging 39.

Arthroscopic Lateral Ligament Repair Through Two Portals in Chronic Ankle Instability.

Objectives: Injury to the lateral ligament complex of the ankle is one of the most common sports-related injury. Usually lateral ankle evolves with excellent clinical recovery with non surgical treatment, however, near about 30% develop a lateral chronic instability sequela. Several open and arthroscopic surgical techniques have been described to treat this medical condition.
