REVIEW
Luigi Piero Solimeno, Gianluigi Pasta
Today, major surgical procedures can be safely performed in hemophilic patients with chronic arthropathy, using available factor concentrates. In this setting, total knee replacement is considered the "gold standard", while the use of total ankle replacement is still debated. Indeed, the unsatisfactory results obtained with the previous available design of implants did not raise enthusiasm as knee or hip replacement. Recently, the introduction of new implant designs and better reported outcomes have renewed the interest in total ankle replacement in people with hemophilia...

Background and purpose - Although the use of patient-specific positioning guides (PSPGs) in total knee replacement (TKR) in theory is promising, the technique has not yet proven its superior- ity compared with the conventional method. We compared radio- logical alignment and clinical outcome between TKR performed with the use of PSPGs and the conventional operation method. Patients and methods - 3 hospitals participated in a prospec- tive trial. 109 patients were randomized to either the conventional method or to the use of PSPGs...

BACKGROUND: Total ankle arthroplasty (TAA) is commonly pursued for patients with painful arthritis. Outpatient TAA are increasingly common and have been shown to decrease costs compared to inpatient surgery. However, there are very few studies examining the safety of outpatient TAA. In this study, we retrospectively reviewed 65 consecutive patients who received outpatient TAA to identify complication rates. METHODS: The medical records of 65 consecutive outpatient TAA from October 2012 to May 2016 with a minimum 6-month follow-up were reviewed...

BACKGROUND: The combination of neurologic deformity of the ankle and foot with osteomyelitis is a therapeutic challenge. We investigated the role of Ilizarov with regard to eradication of infection, correction of deformities and improvement of patient function. METHODS: We retrospectively reviewed 77 patients (77 feet) with neurologic deformity of the ankle and foot with osteomyelitis treated sequentially in 3 stages by Ilizarov method. The 3 stages were (1) active debridement and Ilizarov stabilization, (2) further strengthening of Ilizarov fixator and active osteosynthesis consisting of strategies like arthrodesis, osteotomy distraction, bone transport, or combination thereof, (3) consolidation of fusion/regeneration achieved in second stage...

BACKGROUND: Anesthetic block of the peripheral nerves in the foot and ankle is generally used as anesthesia. The increased use of anesthetic blocks has made this technique an increasingly safe method, and its use has been expanded to postoperative analgesia in foot and ankle surgeries. The objective of this study was to evaluate the analgesia time and pain intensity, using objective scores, after peripheral nerve block in foot and ankle surgeries. METHODS: Patients who underwent surgery by the foot and ankle group of our institution from March 2016 to January 2017 were invited to participate in this prospective, randomized, and blinded study after signing an informed consent form...

BACKGROUND: The diagnosis of medial ankle instability in Weber B ankle fractures remains controversial. Manual stress and gravity stress radiographs as well as magnetic resonance imaging (MRI) are used, but there is no consensus gold standard. The purpose of this study was to determine the relationship between initial fibular displacement and medial clear space widening on a gravity stress radiograph as a predictor of instability. METHODS: A retrospective review was conducted of all patients with isolated Weber B ankle fractures with both initial injury radiographs and gravity stress view from August 1, 2014, through April 1, 2016...

Total ankle replacement (TAR) has evolved over the past decade as a treatment for end-stage ankle arthritis with improved survivorship. Despite the improving outcomes, ankle deformity represents a challenge to the foot and ankle surgeon with increased risk of implant failure. The use of preoperative computer-assisted guidance has led to better understanding the 3-dimensional ankle anatomy and associated deformities and allows for reproducible, anatomic placement of the TAR components.

REVIEW
Justin Tsai, David I Pedowitz
Total ankle arthroplasty is an increasingly popular procedure to address tibiotalar joint arthritis. Implant design and the rationale behind it have changed throughout the years. Newer generation implants allow for minimal resection of bone and use fixed-bearing technology. Long-term follow-up multicenter studies will determine the lifetime of these devices and their effectiveness in addressing pain and improving function for patients with endstage tibiotalar arthritis.

Several studies have shown that subjects with higher serum bilirubin may have a lower risk of cardiovascular disorders. We herein investigated whether serum bilirubin concentration is associated with lower extremity ischemia among cardiology patients. In total, 935 patients without a history of angioplasty or bypass surgery of the lower limb arteries and who had bilateral ankle-brachial index measurements were included in the study. Peripheral arterial disease (PAD) was defined to be present when ABI of either or both sides was <0...

BACKGROUND: Hindfoot arthritis or significant deformity involving the ankle and subtalar joint (STJ) is a disabling condition with few salvage options. Many surgeons note a decreased STJ fusion rate compared with ankle union when a retrograde nail construct is used. The purpose of this study was to report the STJ fusion rate of tibiotalocalcaneal (TTC) arthrodesis with retrograde nail. METHODS: A chart and radiographic review was performed. TTC fusions performed in patients with osteoarthritis, posttraumatic arthritis, or deformity correction with retrograde nail fixation were included...

Background/aim: Hormonal and structural changes that occur during pregnancy cause alterations in body biomechanics. These alterations reach their peak in the last trimester. Adaptive changes that appear in the foot result in pain in the foot and ankle. Pedobarography is a noninvasive measurement method that can be used to understand the origin of such pain. Materials and methods: One hundred and thirty-one pregnant women who did not have a foot or ankle problem prior to pregnancy volunteered to take part in the study...

Extensive hypertrophic scarring of the halluces secondary to chronic onychocryptosis is a rare condition, which causes significant physical and psychosocial effects. In this case, a 31-year-old male developed large lesions on both great toes after he delayed treatment of chronic hallucal onychocryptosis for over a decade. Current treatment options for hypertrophic and keloid lesions in the foot and ankle vary considerably and differentiation is critical for appropriate treatment planning. In this case, surgical excision with total matrixectomy (modified Zadik-Syme) was considered optimal management...

Conversion of ankle arthrodesis to total ankle arthroplasty has recently gained popularity. However, technical challenges are present when treating patients without a sufficient fibular buttress. We describe a technique for restoration of an adequate fibular buttress using an iliac crest bone graft or malleolar relocation. The results of 10 patients with an average follow-up period of 56 (range 24 to 123) months are presented. Of the 10 patients, 3 underwent tricortical iliac bone augmentation of the fibula, 4 underwent repositioning of the remnant fibula, and in 3, the in situ fibula was used...

REVIEW

Interest in outpatient orthopedic surgery has been fueled by provider desire to control costs and development of rapid recovery protocols. Open reduction and internal fixation (ORIF) is a commonly elected treatment strategy for ankle fracture that may be performed in an outpatient setting. Lessons on cost-savings of the outpatient model in orthopedics can be learned in total joint replacement and spine surgery. Moreover, in properly selected patients, outpatient ORIF has been shown to be comparably safe. Reasons for admission of the surgically managed patient with ankle fractures, including concern for surgical delay and additional social factors, warrant further investigation...
