Open ankle fractures in the elderly: predisposing factors and the associated mortality.

The purpose of this study was to investigate the independent effect of open ankle fractures on postoperative mortality and to identify factors leading to open ankle fractures in the elderly population. This is a retrospective case-control study of 1,045 patients aged 65 years and older, with ankle fractures undergoing surgical fixation between 2010 and 2020 at three medical centers (Levels 1-2). A logistic regression analysis was used to identify risk factors for open fractures.

Compressive Strength of Midfoot Fusion Nail vs Midfoot Fusion Bolt and Role of Subtalar Fusion in Midfoot Charcot Fixation Model.

Background: Operative management of midfoot Charcot arthropathy often involves an extended midfoot arthrodesis with intramedullary bolts for fixation, a method called "beaming." Recently intramedullary nails have been introduced for the same indication, presumably providing stronger fixation. This study compares midfoot fusion nails to bolts with regard to stiffness and compressive ability.

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

Objectives: Majority of Lisfranc fracture-dislocations require anatomic reduction and rigid internal fixation to prevent debilitating sequelae. Current methods include solid screws and flexible fixations which have been in use for many years. Biointegrative screw is a newer option that has not yet been thoroughly investigated for its effectiveness for Lisfranc injuries.

Republication of "Stress Fractures of the Foot and Ankle in Athletes".

Stress fractures of the foot and ankle are common injuries in athletes. Management differs considerably based on fracture location and predisposing factors. Repetitive loading of the foot and ankle in athletes should result in physiologic bone remodeling in accordance with Wolff's law.

A Prospective Randomized Controlled Trial Comparing Physical Therapy With Independent Home Stretching for Plantar Fasciitis.

Background: Although formal physical therapy (PT) is effective in treating plantar fasciitis (PF), it is unclear how this compares with home-based plantar fascia stretching (HS).

Methods: Fifty-seven patients with PF were enrolled in a prospective randomized trial comparing PT with HS. Visual analog scale (VAS), Foot and Ankle Ability Measure (FAAM), and Short Form (36) Health Survey (SF-36) scores were analyzed at 6 weeks, 3 months, 6 months, and 1 year.

The Lateral Fibular Stress Test: High Variability of Force Applied by Orthopaedic Surgeons in a Biomechanical Model.

Background: The lateral fibular stress test (LFST), also known as the hook or Cotton test, is commonly performed to assess syndesmotic instability intraoperatively. Several studies have used 100 N as the force applied when performing the LFST to detect syndesmotic instability, though no evidence-based requisite force has been described for the test. We hypothesize that surgeons do not apply force uniformly or consistently when performing the LFST and that substantial variation exists.

Use of a Lightweight Portable Fluoroscopy Device for Obtaining Weightbearing Ankle Images.

Portable fluoroscopy devices provide point-of-care imaging in emergency and out-patient clinics. In this prospective study, we compared weightbearing images of syndesmosis obtained using a novel lightweight portable battery-powered fluoroscopy device with those obtained with a conventional radiography device. Eleven healthy participants underwent bilateral 3-view weightbearing imaging of both ankles using a radiography (X-ray group) device and a portable fluoroscopy system (LPF group).

Factors Related to Neuropathic Pain following Lower Extremity Amputation.

Background: Lower extremity amputations are common, and postoperative neuropathic pain (phantom limb pain or symptomatic neuroma) is frequently reported. The use of active treatment of the nerve end has been shown to reduce pain but requires additional resources and should therefore be performed primarily in high-risk patients. The aim of this study was to identify the factors associated with the development of neuropathic pain following above-the-knee amputation, knee disarticulation, or below-the-knee amputation.

Quality of MIS vs Open Joint Preparations of the Foot and Ankle.

Background: Minimally invasive surgery (MIS) is growing in the field of foot and ankle, and the MIS burr is an emerging tool. Although commonly used to perform osteotomies, the burr can also be used for arthrodesis joint preparation that traditionally would be performed through open incisions. To date, there is no study comparing the quality of joint preparation between using a fluoroscopy-guided MIS technique compared to traditional open techniques.

Novel values in the radiographic diagnosis of ligamentous Lisfranc injuries.

Background: Ligamentous Lisfranc instability is commonly missed on unilateral radiographs. However, measurement protocols for bilateral weightbearing radiographs have not been standardized. The primary aim of this study was to investigate the optimal cut-off values for diagnosing Lisfranc instability by evaluating the side-to-side differences of preoperative bilateral weightbearing radiographs among patients with surgically-confirmed ligamentous Lisfranc instability.

Utility of WBCT to Diagnose Syndesmotic Instability in Patients With Weber B Lateral Malleolar Fractures.

Background: Diagnosing syndesmotic instability accompanying Weber B ankle fractures can be challenging. This study aimed to evaluate the ability of weight-bearing computed tomography (WBCT) to diagnose syndesmotic instability using one-dimensional, two-dimensional, and three-dimensional measurements among patients with unilateral Weber B lateral malleolar fractures with symmetric medial clear space (MCS) on initial radiographs and yet demonstrated operatively confirmed syndesmotic instability.

Methods: The treatment group included 23 patients with unilateral surgically confirmed syndesmotic instability accompanying Weber B ankle fractures who underwent preoperative bilateral foot and ankle WBCT.

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.

Surgical Management of Musculotendinous Balance in the Progressive Collapsing Foot Deformity: The Role of Peroneal and Gastrocnemius Contracture.

Surgical treatment of progressive collapsing foot deformity (PCFD) relies on understanding the dynamic and deforming musculotendinous structures that contribute to hindfoot valgus, forefoot abduction, forefoot varus, and collapse or hypermobility of the medial column. Equinus commonly is seen in PCFD and consideration should be given to isolated gastrocnemius or Achilles lengthening. Although transfer of the flexor digitorum longus tendon is performed in PCFD attributed to dysfunction and pathology of the posterior tibialis tendon (PTT), retention of PTT is an area for further research.

A Limited Fixation, Olecranon Sparing Approach, for Management of Geriatric Intra-Articular Distal Humerus Fractures.

Purpose: We propose that geriatric comminuted intra-articular distal humerus fractures can be effectively treated with a limited fixation approach aimed at achieving varus/valgus stability with columnar fixation, but allowing intra-articular comminution to heal by secondary congruency against an intact olecranon, thus avoiding an olecranon osteotomy.

Methods: Fifty-six elderly patients with AO 13-C type fractures, who underwent surgical fixation with ≥12-months of follow-up were retrospectively reviewed. Thirty patients were treated with intra-articular open reduction internal fixation (ORIF) with an olecranon osteotomy and 26 patients were treated with our limited fixation (L-ORIF) approach.

Getting the Starting Point Right: Prevention of Skiving and Fibular Cortical Breach During Suture Button Placement for Syndesmotic Ankle Injuries.

The use of suture button (SB) devices in the treatment of syndesmotic ankle injuries is increasing. These constructs have demonstrated better syndesmotic reduction, improved clinical outcomes, and lower rates of hardware removal compared with screw fixation. However, placing a SB device without a fibular plate can be technically challenging.

Implant Removal Matrix for the upper Extremity Orthopedic Surgeon.

Orthopedic implant removal is a commonly performed procedure. While implant removal can be associated with improved symptoms, risks of the surgery are notable. Stripped screws, broken and retained hardware, and morbidity associated with soft tissue compromise during difficult removal are all common.

Gunshot-Related Injuries to the Foot & Ankle: Review Article.

Gunshot-related injuries remain a significant and important cause of global morbidity and cost. The foot and ankle has certain anatomic and functional considerations that make gunshot-related injuries challenging to manage. While the scientific literature regarding gunshot-related injuries is extensive, little of the existing literature focuses on the foot and ankle.

Consideration of medial anatomical structures at risk when placing quadricortical syndesmotic fixation: A cadaveric study.

Background: Surgical fixation of syndesmotic instability using quadricortical fixation, whether screws or suture-button devices, places structures on the medial side of the tibia at iatrogenic risk. This study aims to radiographically map the anatomic course of structures on the medial aspect of the distal tibia to be able to at-risk zones (ARZs) for syndesmotic fixation.

Methods: Eighteen fresh-frozen cadaveric ankle specimens were dissected.

Factors influencing treatment recommendations for base of 5th metatarsal fractures in orthopaedic residency programs.

Background: Management of proximal 5th metatarsal fractures remains a controversial topic in orthopaedic surgery. Both operative and non-operative approaches have been described in the clinical setting. This confusion has led to non-standardized treatment recommendations for proximal 5th metatarsal fractures.

Complete Cuboid Dislocation With Associated Lisfranc Injury: A Case Report and Review of the Literature.

Cuboid dislocations are rare midfoot injuries that usually occur in the setting of high-energy trauma. Diagnosis can be challenging and optimal treatment remains unknown. This case report and review aims to summarize the recent literature on this topic.

Correlation of Soft Tissue Swelling and Timing to Surgery With Acute Wound Complications for Operatively Treated Ankle and Other Lower Extremity Fractures.

Background: Considerable debate exists regarding how soft-tissue edema should influence timing of surgery for ankle and other lower extremity fractures. Assessment of swelling is subjective, and timing varies among surgeons. However, timing of surgery is one of the few modifiable factors in fracture care.

Effect of Syndesmotic Implant Removal on Dorsiflexion.

Background: There is limited evidence that syndesmotic implant removal (SIR) is beneficial. However, many surgeons advocate removal based on studies suggesting improved motion. Methodologic difficulties make the validity and applicability of previous works questionable.

A Compatibility Guide for the Orthopaedic Surgeon Planning to Perform Hardware Removal Surgery.

Background: Removal of previously placed orthopaedic implants is a commonly performed procedure worldwide. Given the diversity of orthopaedic implant manufacturers, surgeons may be uncertain whether they have the appropriate screwdriver on site. The purpose of this study was to assess the compatibility of screw head and size configurations from various orthopaedic manufacturers with two commonly used universal screw removal sets.

Implant Removal Matrix for the Foot and Ankle Orthopaedic Surgeon.

Background: Orthopaedic surgery frequently requires the use of metal plate and screw constructs for osteosynthesis. These constructs may be subsequently removed for a variety of indications. In the lower extremity in particular, implants (ie, hardware) can lead to prominence and pain secondary to a thin soft-tissue envelope with little subcutaneous tissue.
