Soon Hyuck Lee, Hyung Jun Park, Eui Dong Yeo, Young Koo Lee
BACKGROUND: Verifying the exact location of talocalcaneal (TC) coalition is important for surgery, but the complicated anatomy of the subtalar joint makes it difficult to visualize on radiographs. No study has used computed tomography (CT) or magnetic resonance imaging (MRI) to verify the radiological characteristics of TC coalition or those of different facet coalitions. Therefore, this study verified the radiological findings used to identify TC coalitions and those of different facet coalitions using CT and MRI...

Isolated posteromedial ankle dislocation is a rare condition thanks to the highly congruent anatomical configuration of the ankle mortise, in which the medial and lateral malleoli greatly reduce the rotational movement of the talus, and the strength of the ligaments higher than the malleoli affords protection against fractures. However, other factors, like medial malleolus hypoplasia, laxity of the ligaments, peroneal muscle weakness and previous ankle sprains, could predispose to pure dislocation. In the absence of such factors, only a complex high-energy trauma, with a rotational component, can lead to this event...

Chul Hyun Park, Woo-Chun Lee
BACKGROUND: The anterior half of the peroneus longus tendon (AHPLT) has been reported to be an effective autograft for ligament reconstruction with respect to strength and safety. However, there is little information regarding donor site morbidity after harvesting the AHPLT. Furthermore, to the best of our knowledge, there has not been a study on the isokinetic evaluation of ankle plantar flexion and eversion after AHPLT harvesting. PURPOSE: To evaluate the clinical and radiographic results after lateral ankle ligament reconstruction using the AHPLT...

OBJECTIVES: We tested cytoplasmic HuR (cHuR) as a predictive marker for response to chemotherapy by examining tumor samples from the international European Study Group of Pancreatic Cancer-3 trial, in which patients with resected pancreatic ductal adenocarcinoma (PDA) received either gemcitabine (GEM) or 5-fluorouracil (5-FU) adjuvant monotherapy. BACKGROUND: Previous studies have implicated the mRNA-binding protein, HuR (ELAVL1), as a predictive marker for PDA treatment response in the adjuvant setting...

Posterior malleolus fractures vary in morphology. A computed tomography scan is imperative to evaluate fragment size, comminution, articular impaction, and syndesmotic disruption. Despite an increasing body of literature regarding posterior malleolus fractures, many questions remain unanswered. Although, historically, fragment size guided surgical fixation, it is becoming evident that fragment size should not solely dictate treatment. Surgical treatment should focus on restoring ankle joint structural integrity, which includes restoring articular congruity, correcting posterior talar translation, addressing articular impaction, removing osteochondral debris, and establishing syndesmotic stability...

: Giant cell tumor (GCT) or osteoclastoma is a benign, locally aggressive tumor with a tendency to recur. Giant cell tumors typically occur in the epiphysis of long bones, including the distal femur and proximal tibia. They are uncommonly found in the small bones of the foot or ankle, and involvement of talus is rare. The authors present a case of GCT of the talar body in a 21-year-old man, which was diagnosed radiologically by the presence of a well-defined osteolytic lesion involving more than half of the talar body with thinning of the cortices...

Previous studies of frontal crash databases reported that ankle fractures are among the most common lower extremity fractures. While not generally life threatening, these injuries can be debilitating. Laboratory research into the mechanisms of ankle fractures has linked dorsiflexion with an increased risk of tibia and fibula malleolus fractures. However, talus fractures were not produced in the laboratory tests and appear to be caused by more complex loading of the joint. In this study, an analysis of the National Automotive Sampling System - Crashworthiness Data System (NASS-CDS) for the years 2004-2013 was conducted to investigate foot-ankle injury rates in front seat occupants involved in frontal impact crashes...

REVIEW
Tahir Ögüt, Necip Selcuk Yontar
Charcot neuroarthropathy is associated with progressive, noninfectious, osteolysis-induced bone and joint destruction. When the ankle and/or hindfoot is affected by the destruction process, management is further complicated with collapse and destruction of the talar body, which increases instability around the ankle. In this patient population, arthrodesis is the most commonly used surgical procedure. Internal fixation, external fixation, or a combination of both can be used for the treatment. Decision making between them should be individualized according to the patient characteristics...

Over the past decade, emerging technologies have provided new insights into the genomic landscape of pancreatic ductal adenocarcinoma (PDA). In addition to the commonly recognized genetic drivers of pancreatic carcinogenesis (KRAS, CDKN2A, TP53, SMAD4), new genes and pathways have been implicated. However, these efforts have not identified any new high-frequency actionable mutations, limiting the success of mutation-targeted therapy in PDA. This article provides a report on the current landscape of pancreas cancer genetics and targeted therapeutics...

Introduction. Ankle arthrodesis is performed in a variety of methods. We propose a new technique for tibiotalar arthrodesis using a newly designed intramedullary nail. Methods. We proposed development of an intramedullary device for ankle arthrodesis which spared the subtalar joint using a sinus tarsi approach. Standard saw bones models and computer assisted modeling and stress analysis were used to develop different nail design geometries and determine the feasibility of insertion. After the final design was constructed, the device was tested on three cadaveric specimens...

Gradual distal fibula lengthening (DFL), in conjunction with other procedures, was used to correct ankle valgus and short fibulae in three pediatric patients with multiple hereditary exostoses (MHE). The average amount of DFL was 15 mm with a mean follow-up of 2.9 years. Final radiographs showed that all three patients had a stable ankle mortise without evidence of talar tilt or widening. In conclusion, gradual DFL has the advantage of restoring anatomy in cases of ankle valgus due to short fibulae and MHE, and may be performed in conjunction with other procedures...

We report two cases of acute fractures of the os trigonum. The os trigonum fracture related to the first case was sustained following a hyper-plantar flexion injury during a game of soccer. The second case involved a patient who fell from height and also sustained open fractures of the left distal tibia and lateral malleolus as well as the right calcaneus. In both cases, a preliminary diagnosis of a posterior talar process fracture was made from the initial radiographs of the ankle. The correct diagnosis of an os trigonum fracture rather than a fracture of the posterior talar process was only made following further assessment with CT imaging...

BACKGROUND: A precise pre-operative measurement of hindfoot malalignment is paramount to plan and obtain an accurate surgical correction. Hindfoot alignment is currently determined on standard weightbearing radiographs. However this is hampered by the superposition of the skeletal structures. Recent technology developed weightbearing cone beam CT to overcome this problem. The objective is to introduce a clinically relevant and reproducible method to measure hindfoot alignment on weightbearing CT...

BACKGROUND: Lisfranc (tarsometatarsal joint) injuries are relatively rare, accounting for less than 1% of all fractures, and as many as 20% of subtle Lisfranc injuries are missed at the initial patient presentation. An undiagnosed Lisfranc injury can have devastating consequences to the patient. Therefore, any factor that can raise a clinician's index of suspicion to make this diagnosis is potentially important. The cavus foot has been associated with various maladies of the lower extremity, but to our knowledge, it has not been reported to be associated with Lisfranc injury...

Though conventionally not considered standard of care, nonoperative management of patients with small bowel obstruction (SBO) without previous abdominal operations, so called "virgin abdomens," (VA) is presently being practiced. We aimed to determine outcomes of patients with VA undergoing operative and nonoperative management of SBO. A retrospective review of patients with SBO was performed; outcomes of patients with VA were analyzed. SBO with a VA was found in 103 patients over a 5-year period. With a mean follow-up of 4...

We treated 2 patients with progressive, refractory scleroderma with a combined immunotherapy approach using plasmapheresis followed by rituximab and then intravenous umbilical-cord-derived allogeneic mesenchymal stem cells (MSCs). Both patients improved subjectively and objectively for over a year. Upon recurrence of their symptoms, the patients were treated again with allogeneic MSCs alone with a very good response. The combination was well tolerated and effective suggesting a large scale study may be warranted in progressive, refractory Scleroderma...
