The Biomechanical Role of the Deltoid Ligament on Ankle Stability: Injury, Repair, and Augmentation.

Background: Deltoid ligament injuries occur in isolation as well as with ankle fractures and other ligament injuries. Both operative treatment and nonoperative treatment are used, but debate on optimal treatment continues. Likewise, the best method of surgical repair of the deltoid ligament remains unclear.

Malignant neoplasms originating from the bones of the foot: Predilection of hematological malignancies and sex-related and ethnic disparities in amputation.

Purpose: Neoplasms originating from the "small bones of the lower limb and the overlapping joints" are rare but portend a serious prognosis. Current study utilizes a population-based registry in the United States to characterize the malignancies of the foot.

Methods: National Cancer Institute's Surveillance, Epidemiology and End Result database from 1975 to 2017 was queried to report incidence and survival data in 514 patients in the Uited States.

Augmented Spring Ligament Repair in Pes Planovalgus Reconstruction.

Patients with pes planovalgus deformity often have coexisting spring ligament pathology. A primary repair of the ligament may fail during weightbearing due to chronic degeneration of the ligamentous tissue. Augmentation with a suture tape has been suggested to strengthen the repair.

Anterior Syndesmotic Augmentation Technique Using Nonabsorbable Suture-Tape for Acute and Chronic Syndesmotic Instability.

Syndesmotic instability is a source of significant pain and disability. Both subtle instability and gross diastasis, whether acute or chronic, require stabilization and may benefit from reconstruction with ligamentous augmentation. The use of nonabsorbable suture-tape has emerged as a promising operative strategy, allowing surgeons to anatomically reconstruct the syndesmosis, in particular the anterior inferior tibiofibular ligament.

Effect of Postoperative Oral Antibiotics on Infections and Wound Healing Following Foot and Ankle Surgery.

Background: There is controversy regarding the effectiveness of postoperative antibiotics to prevent wound infection. Some surgeons still use a routine postoperative oral antibiotic regimen. The purpose of this study was to review a series of cases and document statistically any difference in infection rates and whether routine postoperative antibiotics in foot and ankle surgery are justified.

Purpose: The aim of this study was to investigate the biomechanical properties of the InternalBrace for lisfranc injuries.

Methods: A Sawbone model was developed comparing screw, suture button and InternalBrace.

Results: When loaded in axial tension at 0.

Flexible Fixation Technique for Lisfranc Injuries.

Injuries to the Lisfranc complex range from purely ligamentous disruptions to fracture-dislocations of the tarsometatarsal joint. Treatment options include closed/open reduction with percutaneous pinning, open reduction and internal fixation (ORIF), and primary arthrodesis. We present a ligament reinforcement technique utilizing a flexible fixation device for the treatment of ligamentous Lisfranc injuries.

Tarsal Tunnel Syndrome Secondary to Accessory Musculature: A Case Report.

Tarsal tunnel syndrome (TTS) is a relatively uncommon compression neuropathy caused by impingement of the tibial nerve or one of the terminal branches. The presence of accessory musculature at the posteromedial aspect of the ankle has been identified as a rare cause of this condition. Despite the rarity of this condition, it must be considered in patients with refractory symptoms consistent with tibial nerve dysfunction.

Subchondroplasty of the Ankle and Hindfoot for Treatment of Osteochondral Lesions and Stress Fractures: Initial Imaging Experience.

To describe the imaging findings of patients treated with subchondroplasty (SCP) of the ankle and hindfoot. Eighteen patients (10 men, 8 women; age mean 43.1 years [range 20.

Foot and Ankle Injuries in Soccer.

The ankle is one of the most commonly injured joints in soccer and represents a significant cost to the healthcare system. The ligaments that stabilize the ankle joint determine its biomechanics-alterations of which result from various soccer-related injuries. Acute sprains are among the most common injury in soccer players and are generally treated conservatively, with emphasis placed on secondary prevention to reduce the risk for future sprains and progression to chronic ankle instability.

The Influence of Percentage Weight-Bearing on Foot Radiographs.

Clinical decisions are often made on weight-bearing radiographs. However, it is unknown whether various weight-bearing conditions alter specific radiographic measurements. The purpose of this study was to determine whether percentage weight-bearing influences radiographic measurements of the normal foot.

Effects of Micronized Cartilage Matrix on Cartilage Repair in Osteochondral Lesions of the Talus.

Background: The repair of osteochondral lesions remains a challenge due to its poor vascularity and limited healing potential. Micronized cartilage matrix (MCM) is dehydrated, decellularized, micronized allogeneic cartilage matrix that contains the components of native articular tissue and is hypothesized to serve as a scaffold for the formation of hyaline-like tissue. Our objective was to demonstrate that the use of MCM combined with mesenchymal stem cells (MSCs) can lead to the formation of hyaline-like cartilage tissue in a single-stage treatment model.

Removable Rigid Dressings for Postoperative Management of Transtibial Amputations: A Review of Published Evidence.

Unlabelled: Forty years of clinical experience and peer-reviewed research studies support the use of nonweight-bearing removable rigid dressings (RRDs) as an effective means of postoperative management of transtibial amputations. We reviewed the published medical evidence regarding the use of RRDs as a postoperative management strategy, culminating in an evidence-based practice recommendation. Published peer-reviewed literature on the topic was searched and classified by level of evidence based on the research design using the scale recommended by the PM&R (level I through V).

Seven-Year Follow-up of Matrix-Induced Autologous Implantation in Talus Articular Defects.

Background: Osteochondral lesions of the talus (OLT) are difficult to treat because of the poor intrinsic healing capability of articular cartilage. Matrix-induced autologous chondrocyte implantation (MACI) has been shown to be a reliable method for treating cartilage lesions that fail to respond to traditional microfracture and debridement. The purpose of this study was to assess 7-year clinical follow-up data of this technique and demonstrate midterm success of this implant.

Technique for Use of Trabecular Metal Spacers in Tibiotalocalcaneal Arthrodesis With Large Bony Defects.

There are many causes of large bone defects in the tibiotalar joint that need to be definitively treated with a tibiotalocalcaneal (TTC) arthrodesis. Some of the challenges of a large defect are its effect on leg length and the complications associated with trying to fill the defect with structural bone graft. We present an operative strategy involving the use of a trabecular metal implant, a TTC nail that utilized 2 forms of compression, and Reamer/Irrigator/Aspirator (RIA) autograft, to address limitations of previous operative approaches and reliably treat this operative challenge.

Subtalar joint arthrodesis: open and arthroscopic indications and surgical techniques.

Arthrodesis of the subtalar joint can be performed via both open and arthroscopic techniques. Both groups of procedures have their own relative indications and contraindications, as well as complications. Good results have been reported for both general procedures, although some studies suggest superiority with arthroscopic subtalar arthrodesis.

Viability of talus osteochondral defect cartilage for chondrocyte harvesting: results of 151 patients.

Background: Large talar cartilage defects can be treated with either autologous chondrocyte implantation or matrix autologous chondrocyte implantation. Both techniques depend on successful harvesting of the chondrocytes. In the past, they have come from the ipsilateral knee, which has been associated with donor site morbidity.
