Outcomes of Charcot-Marie-Tooth Disease Cavovarus Surgical Reconstruction.

Background: Charcot-Marie-Tooth (CMT) disease is a progressive inherited neurologic disorder causing muscle weakness and lower extremity deformity. The goal of foot and ankle surgical treatment is to create a stable, plantigrade foot, with the potential elimination of brace-wear for ambulation. The aim of this study was to report baseline CMT patient function and subsequent outcome improvement from surgical treatment, as determined by PROMIS physical function (PF), pain interference (PI), and mental health/depression (D) scores.

Méary's angle decoded: 3D analysis of first ray plantarflexion deformity in Charcot-marie-tooth disease.

Background: The typical cavovarus deformity seen in patients with Charcot-Marie-Tooth (CMT) involves plantarflexion of the first ray. The exact apex of the deformity has never been proven, although it is presumed to be within the medial cuneiform. The aim of this study was to utilize weight-bearing computed tomography (WBCT) to localize and quantify first ray plantarflexion deformity in CMT patients.

3D Analysis of Joint-Sparing Charcot-Marie-Tooth Surgery Effect on Initial Standing Foot Alignment.

Background: The complex deformities in cavovarus feet of Charcot-Marie-Tooth (CMT) disease are difficult to evaluate. The aim of this study was to quantify the initial standing alignment correction achieved after joint-sparing CMT cavovarus reconstruction using pre- and postoperative weightbearing computed tomography (WBCT).

Methods: Twenty-nine CMT cavovarus reconstructions were retrospectively analyzed.

Charcot-Marie-Tooth Disease: A Surgical Algorithm.

In Charcot-Marie-Tooth (CMT) cavovarus surgery, a regimented approach is critical to create a plantigrade foot, restore hindfoot stability, and generate active ankle dorsiflexion. The preoperative motor examination is fundamental to the algorithm, as it is not only guides the initial surgical planning but is key in the decision making that occurs throughout the operation. Surgeons need to be comfortable with multiple techniques to achieve each surgical goal.

Does Screw Order Matter? A Technique Tip to Prevent Loss of Fracture Reduction during Surgical Fixation of Lateral Malleolus Fractures.

When obtaining surgical fixation of lateral malleolus fractures, a cortical lag screw is commonly used to obtain anatomic reduction. Subsequently, a neutralization plate is applied. Slight loss of fracture reduction after plate placement occasionally occurs.

Charcot-Marie-Tooth Disease of the Foot and Ankle: Imaging Features and Pathophysiology.

Charcot-Marie-Tooth disease (CMT) is the most common inherited peripheral polyneuropathy, resulting in length-dependent motor and sensory deficiencies. Asymmetric nerve involvement in the lower extremities creates a muscle imbalance, which manifests as a characteristic cavovarus deformity of the foot and ankle. This deformity is widely considered to be the most debilitating symptom of the disease, causing the patient to feel unstable and limiting mobility.

Isolated Gastrocnemius Recession for Progressive Collapsing Foot Deformity.

Introduction: Progressive collapsing foot deformity (PCFD) is frequently associated with a gastrocnemius contracture. Surgical treatment of PCFD often includes a gastrocnemius recession in addition to other corrective procedures, which typically requires a period of restricted weight bearing postoperatively. Isolated gastrocnemius recession may allow passive correction of the deformity, improve orthotic fit, and obviate the need for full reconstruction and restricted weight bearing.

Reliability of Fifth Metatarsal Base Fracture Classifications and Current Management.

Background: Classification of fifth metatarsal base fractures has been a source of confusion since originally described by Jones in 1902. Zone classifications have been described but never evaluated for reliability. The most recent classification, metaphyseal vs meta-diaphyseal, may be unknown to many surgeons.

Abnormal Bone Morphology in Charcot-Marie-Tooth Disease.

Background: Although long suspected, it has yet to be shown whether the foot and ankle deformities of Charcot-Marie-Tooth disease (CMT) are generally associated with abnormalities in osseous shape. Computed tomography (CT) was used to quantify morphologic differences of the calcaneus, talus, and navicular in CMT compared with healthy controls.

Methods: Weightbearing CT scans of 21 patients (27 feet) with CMT were compared to those of 20 healthy controls.

Addressing Common Questions About Traveling by Air After Orthopedic Surgery.

Many patients have questions about traveling by air after orthopedic surgery. The goal of this review was to provide a guide to addressing these issues to better prepare patients for air travel. A comprehensive literature review was conducted to address patient questions regarding metal detectors, as well as deep venous thrombosis risk with flying.

Endoscopic Haglund's Resection and Percutaneous Double-Row Insertional Achilles Repair.

Insertional Achilles tendinopathy can be a debilitating condition that often fails to improve with nonsurgical management such as bracing and physical therapy. Traditional surgical techniques include an open debridement of the diseased tendon and resection of calcaneal spurs. This is followed by repair of the tendon.

The Ischemic toe following forefoot surgery: A review of current practices and a proposed approach for management.

Toe hypoperfusion is a commonly encountered concern following forefoot surgery, yet there is limited clinical guidance available to surgeons to aid in management of this scenario. This work aims to review the etiology, pathophysiology and current strategies to address a perioperative ischemic toe. The authors review various interventions to approach this problem based on available evidence and clinical experience.

Biomechanical Comparison of Achilles Tendon Pullout Strength Following Midline Tendon-Splitting and Endoscopic Approaches for Calcaneoplasty.

Background: Calcaneoplasty is a common procedure performed for the management of Haglund's syndrome when nonoperative management fails. Midline tendon-splitting and endoscopy are 2 common approaches to calcaneoplasty. Studies have suggested that an endoscopic approach may allow earlier return to activity and superior outcomes, but there are no biomechanical or clinical studies to validate these claims.

Use of 3D Prints to Compare the Efficacy of Three Different Calcaneal Osteotomies for the Correction of Heel Varus.

Background: Cavovarus deformity of the hindfoot is typically caused by neurologic disorders. Multiple osteotomies have been described for the correction of varus deformity but without clinical comparison. In this study, we used 18 identical 3-dimensional (3D) prints of a patient with heel varus to compare the operative correction obtained with Dwyer, oblique, and Z osteotomies.

The ability of massive osteochondral allografts from the medial tibial plateau to reproduce normal joint contact pressures after glenoid resurfacing: the effect of computed tomography matching.

Background: Current techniques for resurfacing of the glenoid in the treatment of arthritis are unpredictable. Computed tomography (CT) studies have demonstrated that the medial tibial plateau has close similarity to the glenoid. The purpose of this study was to assess contact pressures of transplanted massive tibial osteochondral allografts to resurface the glenoid without and with CT matching.

An anatomical study of the acetabulum with clinical applications to hip arthroscopy.

Background: The clock face has been employed to define the position of labral pathology in relation to identifiable arthroscopically relevant acetabular landmarks. The purpose of this study was to qualitatively and quantitatively describe arthroscopically relevant anatomy of the acetabulum. We aimed to present a surgical landmark that is located in close proximity to the usual location of labral pathology as an alternative to the midpoint of the transverse acetabular ligament as a reference point.

Surgical anatomy of the sternoclavicular joint: a qualitative and quantitative anatomical study.

Background: The quantitative anatomical relationships of the main ligamentous, tendinous, and osseous structures of the sternoclavicular joint have not been widely investigated. The purpose of this study was to provide a quantitative description of the sternoclavicular joint in relation to relevant surgical landmarks.

Methods: We dissected eleven nonpaired, fresh-frozen cadaveric sternoclavicular joints from four men and seven women (mean age at death, fifty-three years; range, thirty-three to sixty-four years) and measured the ligaments, musculature, and osseous landmarks with use of a three-dimensional coordinate-measuring device.

Qualitative and Quantitative Anatomic Investigation of the Lateral Ankle Ligaments for Surgical Reconstruction Procedures.

Background: Lateral ankle sprains are common sports injuries that may require surgery for chronic lateral ankle instability. Anatomic repair or reconstruction is desired, yet there is a scarcity of quantitative information regarding the origins and insertions of the lateral ligaments related to surgically pertinent osseous landmarks.

Methods: Fourteen ankle specimens were dissected to isolate the anterior talofibular ligament, calcaneofibular ligament, posterior talofibular ligament, and cervical ligament.

Surgically Relevant Bony and Soft Tissue Anatomy of the Proximal Femur.

Background: Hip endoscopy facilitates the treatment of extra-articular disorders of the proximal femur. Unfortunately, current knowledge of proximal femur anatomy is limited to qualitative descriptions and lacks surgically relevant landmarks.

Purpose: To provide a quantitative and qualitative analysis of proximal femur anatomy in reference to surgically relevant bony landmarks.

A qualitative and quantitative analysis of the attachment sites of the proximal hamstrings.

Purpose: Proximal hamstring tears represent a challenge. Surgical repair of such tears has been reported utilizing both open and endoscopic techniques. It was hypothesized that the proximal attachments of the hamstring muscle group could be reproducibly and consistently measured from pertinent bony anatomical reference landmarks.

A quantitative analysis of hip capsular thickness.

Purpose: The purpose of this study was to provide a comprehensive quantitative analysis of capsular thickness adjacent to the acetabular rim in clinically relevant locations.

Methods: Dissections were performed and hip capsular measurements were recorded on 13 non-paired, fresh-frozen cadaveric hemi-pelvises using a coordinate measuring device. Measurements were taken for each clock-face position at 0, 5, 10 and 15 mm distances from the labral edge.

The ligament anatomy of the deltoid complex of the ankle: a qualitative and quantitative anatomical study.

Background: The deltoid ligament has both superficial and deep layers and consists of up to six ligamentous bands. The prevalence of the individual bands is variable, and no consensus as to which bands are constant or variable exists. Although other studies have looked at the variance in the deltoid anatomy, none have quantified the distance to relevant osseous landmarks.
