Arthroscopic Treatment of the Septic Ankle.

Ankle joint sepsis is a relatively rare but potentially devastating pathologic process of the lower extremity that requires expeditious identification and management. Establishing the diagnosis of ankle joint sepsis is often challenging as it may present with concomitant pathologies and often lacks consistency in regard to classic clinical characteristics. Once a diagnosis has been established, prompt management is imperative to minimize the potential for long-term sequelae.

First Tarsometatarsal Joint Fusion for Hallux Valgus Deformity: A Retrospective Comparison of Two Fixation Constructs Regarding Initial Maintenance of Correction and Complications: Traditional Crossing Screw Fixation Versus Dorsomedial Locking Plate and Intercuneiform Compression Screw.

Various fixation constructs exist to address hallux valgus when performing a first tarsometatarsal joint arthrodesis. The goal of this present study is to compare complication rates, and degree and maintenance of angular correction between a dorsomedial locking plate with intercuneiform compression screw construct versus traditional crossing solid screw fixation construct. The plate plus intercuneiform compression screw construct fixation utilized a combined sagittal saw and curette method of joint preparation while the crossed screw fixation group utilized a curette and bur technique.

Assessment of Bone Mineral Density in the Distal Tibia Using Quantitative Hounsfield Samples From Computer Tomography.

The distal tibia bone quality is of paramount importance for ankle fractures, total ankle implants, ankle fusions, and osteotomy procedures. Despite this fact relatively little is known regarding the overall bone quality for this section of the tibia. Previous literature suggest that there is a statistically significant decrease in bone mineral density within the distal 5% to 10% segment of the tibia medullary canal.

Medial Malleolar Screw Length to Achieve Thread Purchase in the Dense Bone of the Tibial Epiphyseal Scar Location Based on CT Model.

Medial malleolar ankle fractures are one of the most common surgically treated fractures of the ankle joint. Current AO guidelines for medial malleolar fractures recommend 2 partially threaded cancellous screws across the fracture line. For these screws to cross the fracture line, the threads must purchase the distal tibial metaphysis, which is an area of decreased bone density especially in elderly osteoporotic bone.

A Novel Manipulation Technique for Lapidus Fusion in Correction of Hallux Valgus Deformity With Underlying Metatarsus Adductus: A Case Series.

Underlying metatarsus adductus (MA) is commonly seen in patients with hallux valgus (HV) deformity, with implications regarding procedure selection and hallux valgus recurrence. Lapidus, or first tarsometatarsal fusion, is commonly performed allowing reduction in intermetatarsal angle (IMA) but this procedure has not been established as an approach to provide partial correction of MA deformity. Retrospective assessment of preoperative and postoperative metatarsus adductus angle (MAA), IMA and hallux abductus angle (HAA) in patients treated with Lapidus fusion for HV.

A Review of Consecutive Cases to Identify the Rate of Underlying Osteomyelitis in Patients Undergoing Surgical Treatment of Gangrene of the Forefoot and Impact of Acute Infection on Outcome Following Amputation.

Medical literature offers no clear treatment guidelines when performing amputations for gangrene of the forefoot despite a high percentage that suffer poor outcome due to infection. Gas gangrene and wet gangrene are often preceded by dry stable gangrene. This is a retrospective review of consecutive patients who underwent forefoot amputation and bone biopsy as treatment of forefoot gangrene by a single surgeon.

Predicting Postoperative Sagittal Plane Alignment of the Foot Using Intraoperative Simulated Weightbearing Lateral Imaging During Flatfoot Reconstructive Surgery: A Short-Term Retrospective Analysis.

The sagittal plane relationship of the hindfoot and midfoot joints is a primary determinant of proper alignment in flatfoot reconstructive surgery as assessed both clinically and on postoperative weightbearing (WB) lateral radiographs. The traditional approach to intraoperative radiographic imaging allows for accurate assessment of fixation placement but only a crude evaluation of final sagittal plane alignment. Surgeons employ various methods in an attempt to load the foot during lateral imaging.

Accuracy of Palpation to Identify the Medial Branch of the Medial Dorsal Cutaneous Nerve in Medial Column Surgery: Correlation of Preoperative Nerve Marking With Intraoperative Findings During Lapidus Fusion.

The medial branch of the medial dorsal cutaneous nerve is frequently encountered in medial column surgery. Postoperative sensory nerve symptoms can lead to dissatisfaction and suboptimal outcome. The purpose of this case series is to correlate intraoperative nerve location on direct viewing with preoperative nerve localization to assess the accuracy of a specific nerve palpation technique.

Ideal Angle of Upper and Lower Syndesmotic Fixation Based on Weightbearing Computed Tomographic Imaging in Uninjured Ankles.

Syndesmotic fixation remains a controversial topic, however most authors recommend fixation of the disrupted syndesmotic complex in unstable ankle fractures. There is no clear reference for the angle of syndesmotic fixation, historically 30° has been cited but recently refuted, with new and current literature. It is common practice to place 2 points of transyndesmotic fixation one with fixation placed at around 2 cm above the ankle joint and the second point approximately 3.

Cheilectomy Combined With First Tarsometatarsal Joint Arthrodesis for Surgical Treatment of Midstage Hallux Rigidus Complicated by Medial Column Insufficiency: Prospective Evaluation of Outcomes.

The role of metatarsus primus elevatus and first ray hypermobility is under scrutiny with regard to the pathoanatomy of hallux rigidus. Regardless of the underlying biomechanical cause, there is a subset of patients with hallux limitus present with concomitant insufficiency of the medial column identified on clinical exam and lateral imaging as dorsal divergence of the first compared with the second metatarsal. While cheilectomy and decompression metatarsal osteotomy are commonly used to mitigate retrograde forces at the first metatarsophalangeal joint (MPJ) level, traditional hallux limitus procedures do not address more proximal deformity of the medial column.

Surgical Outcomes After Minimally Invasive Release of Stroke-Related Equinovarus Contracture of the Foot and Ankle.

Cerebrovascular accident frequently causes spastic equinovarus contracture of the foot and ankle, for which traditional surgical correction involves tendon transfer, osteotomy, and hindfoot fusion, which can be challenging for patients after cerebrovascular accident. We prospectively assessed the efficacy of a minimally invasive, ambulatory approach to correct this complex deformity in 12 consecutive patients. Surgery included Achilles tendon lengthening, lengthening of the posterior tibial tendon, and flexor tenotomy of all 5 digits.

Can We Abandon Saw Wedge Resection in Lapidus Fusion? A Comparative Study of Joint Preparation Techniques Regarding Correction of Deformity, Union Rate, and Preservation of First Ray Length.

The traditional joint preparation technique for Lapidus fusion involves wedge resection using a saw to achieve correction of intermetatarsal angular deformity. The main drawback of this approach is undesirable shortening of the first ray, which can predispose to second ray overload that may preclude the procedure for a subset of patients or may necessitate second metatarsal shortening osteotomy. The goal of this study was to determine whether a first ray length-preserving joint preparation technique (curette and bur) achieves equivalent correction of deformity and fusion rate without first ray shortening compared with the standard saw wedge resection technique.

Achilles Lengthening and Multiple Z-Plasty in Parallel for Correction of Toe Walking Associated With Burn Scar Equinus Contracture.

The literature is sparse regarding treatment of burn scar equinus contracture, with focus primarily on staged procedures, serial casting, and gradual correction using external fixation in combination with soft-tissue procedures. This case study describes a single-stage ambulatory approach for late-stage correction of burn scar equinus contracture associated with toe walking. A case report is presented of an 11-year-old male with focus on procedure selection, surgical technique, and 12-month follow-up results.

Combined Medial Column Arthrodesis with Open Reduction Internal Fixation of Central Column for Treatment of Lisfranc Fracture-Dislocation: A Review of Consecutive Cases.

Lisfranc fracture-dislocations can be devastating injuries with significant long-term sequelae with or without surgical intervention. The main goal of treatment is to minimize the common long-term complications including pain, progressive arch collapse, degenerative joint disease, hardware failure, and reoperation. Partial primary fusion involving the first, second, and third tarsometatarsal joints has become a common approach for primarily dislocation injuries, with open reduction and internal fixation (ORIF) favored for Lisfranc injuries involving fracture.

Distal Syme Hallux Amputation for Tip of Toe Wounds and Gangrene Complicated by Osteomyelitis of the Distal Phalanx: Surgical Technique and Outcome in Consecutive Cases.

Distal hallux gangrene and neuropathic ulceration associated with digit deformity frequently result in osteomyelitis of the distal phalanx. Ideal treatment would involve limited resection to preserve function. We describe our surgical technique and retrospective results for distal Syme hallux amputation with plantar flap closure.

Cotton Osteotomy in Flatfoot Reconstruction: A Review of Consecutive Cases.

The Cotton osteotomy or opening wedge medial cuneiform osteotomy is a useful adjunctive flatfoot reconstructive procedure that is commonly performed; however, the outcomes are rarely reported owing to the adjunctive nature of the procedure. The Cotton procedure is relatively quick to perform and effectively corrects forefoot varus deformity after rearfoot fusion or osteotomy to achieve a rectus forefoot to rearfoot relationship. Proper patient selection is critical because the preoperative findings of medial column joint instability, concomitant hallux valgus deformity, or degenerative joint disease of the medial column might be better treated by arthrodesis of the naviculocuneiform or first tarsometatarsal joints.

Two-View Gravity Stress Imaging Protocol for Nondisplaced Type II Supination External Rotation Ankle Fractures: Introducing the Gravity Stress Cross-Table Lateral View.

Assessing ankle stability in nondisplaced Lauge-Hansen supination external rotation type II injuries requires stress imaging. Gravity stress mortise imaging is routinely used as an alternative to manual stress imaging to assess deltoid integrity with the goal of differentiating type II from type IV injuries in cases without a posterior or medial fracture. A type II injury with a nondisplaced fibula fracture is typically treated with cast immobilization, and a type IV injury is considered unstable and often requires operative repair.

Cotton Osteotomy in Flatfoot Reconstruction: A Case Report Highlighting Surgical Technique and Modified Incision to Protect the Medial Dorsal Cutaneous Nerve.

The Cotton osteotomy or opening wedge medial cuneiform osteotomy is a useful adjunctive flatfoot reconstructive procedure that is rarely performed in isolation. The Cotton procedure is relatively quick to perform and effectively corrects forefoot varus deformity after rearfoot fusion or osteotomy to achieve a rectus forefoot to rearfoot relationship. Proper patient selection is critical, because preoperative findings of medial column joint instability, concomitant hallux valgus deformity, or degenerative joint disease of the medial column might be better treated with arthrodesis of the naviculocuneiform or first tarsometatarsal joints.

Vitamin D Levels Do Not Predict Risk of Metatarsal Fractures.

Introduction: In the literature, there is conflicting data regarding the relationship between vitamin D and fractures. Reports on the effects of vitamin D levels on pathologies of the foot and ankle are limited. The purpose of this study is to assess the prevalence of vitamin D insufficiency in patients who have sustained low-energy metatarsal fractures compared to foot or ankle sprains without osseous involvement.

Intraoperative Simulated Weightbearing Lateral Foot Imaging: The Clinical Utility and Ability to Predict Sagittal Plane Position of the First Ray in Lapidus Fusion.

The sagittal plane relationship of the first to second ray is a primary determinant of proper alignment in Lapidus midfoot fusion as assessed both clinically and on postoperative weightbearing lateral radiographs. The traditional approach to intraoperative fluoroscopic imaging allows for accurate assessment of fixation placement and intermetatarsal angle correction but only a crude evaluation of final sagittal plane alignment. Surgeons have used various methods in an attempt to load the foot during lateral imaging.

Complete Fifth Ray Amputation With Peroneal Tendon Transfer to the Cuboid: A Review of Consecutive Cases Involving Lateral Column Neuropathic Foot Ulceration and Osteomyelitis.

Nonhealing wounds along the fifth metatarsal associated with neuropathy and bone deformity frequently become complicated with osteomyelitis. Our surgical technique for complete fifth ray amputation with peroneal tendon transfer has been previously published. The present study evaluated the outcomes regarding success with initial healing and intermediate-term limb survival after this procedure, which is intended to resolve infection, remove bone deformity, heal and prevent recurrence of lateral column wounds, and maintain functional stability of the foot.

Incidence and Clinical Significance of Heterotopic Ossification After Partial Ray Resection.

Heterotopic bone growth is a common finding after partial foot amputation that can predispose to recurrent wounds, osteomyelitis, and reamputation. Heterotopic ossification is the formation of excessive mature lamellar bone in the soft tissues adjacent to bone that is exacerbated by trauma or surgical intervention. The relevance of heterotopic ossification is dependent on its anatomic location.

Two-Pin Fixation of Proximal Interphalangeal Joint Fusion for Hammertoe Correction.

Single-pin external Kirschner wire (K-wire) fixation has traditionally been a mainstay in proximal interphalangeal joint fusion for central hammertoe repair. Concerns over cosmesis, inconvenience, pin tract infection, hardware failure, nonunion, and early hardware removal have led to the development of implantable internal fixation devices. Although numerous implantable devices are now available and represent viable options for hammertoe repair, they are costly and often pose a challenge in the event removal becomes necessary.

Angle and Base of Gait Long Leg Axial and Intraoperative Simulated Weightbearing Long Leg Axial Imaging to Capture True Frontal Plane Tibia to Calcaneus Alignment in Valgus and Varus Deformities of the Rearfoot and Ankle.

The long leg axial view is primarily used to evaluate the frontal plane alignment of the calcaneus in relation to the long axis of the tibia when standing. This view allows both angular measurement and assessment for the apex of varus and valgus deformity of the rearfoot and ankle with clinical utility in the preoperative, intraoperative, and postoperative settings. The frontal plane alignment of the calcaneus to the long axis of the tibia is rarely fixed in the varus or valgus position because of the inherent flexibility of the foot and ankle, which makes patient positioning critical to obtain accurate and reproducible images.

American College of Foot and Ankle Surgeons' clinical consensus statement: risk, prevention, and diagnosis of venous thromboembolism disease in foot and ankle surgery and injuries requiring immobilization.

The purpose of this document is to provide guidance for physicians regarding the risk, prevention, and diagnosis of venous thromboembolism disease after foot and ankle surgery and while caring for lower extremity injuries that require ankle immobilization. A panel composed of all authors of this document reviewed the published evidence and, through a series of meetings, reached consensus regarding the viewpoints contained herein. We conclude that routine chemical prophylaxis is not warranted; rather, patients should be stratified and have a prevention plan tailored to their individual risk level.
