Hans Zwipp, Michael Borrmann, Eberhard Walter
The goal of this paper is to report our experience with hindfoot fractures using our specially developed boot, with a follow-up of 557 cases. This boot works like the well-known Allgöwer-Röck ortheses (ARO), but is a hybrid between a boot and an orthesis. It allows full weightbearing without using crutches and completely protects an acutely operated hind foot fracture, hind foot arthrodesis or a hind foot fracture which is suitable for conservative treatment. In its first generation, this boot was custom made and used in 408 cases, from March 1999 to February 2011...

PURPOSE: Ankle fracture dislocations represent a great threat for soft tissue viability and articular instability. The use of a temporary ankle bridging ExFix plays a fundamental role in the local damage control orthopaedics while waiting for definitive synthesis. METHODS: For this prospective research, we have developed a full application protocol of innovative diaphyseal monocortical screws fixator (Unyco-Orthofix(TM)) exclusively under local anaesthesia. Rigid selection criteria allowed us to collect nine patients during a period of almost 2 years...

BACKGROUND: Hindfoot fractures pose a considerable challenge to military orthopaedic surgeons, as combat injuries are typically the result of energy transfers not seen in civilian practice. This study aimed to characterize the pattern of hindfoot injuries sustained by UK military casualties in recent conflicts, define the early amputation and infection rate, and identify factors associated with poor early outcomes. METHODS: The UK Joint Theatre Trauma Registry was searched for British military casualties sustaining a hindfoot fracture from Iraq and Afghanistan between 2003 and 2014...

REVIEW
Greg A J Robertson, Alexander M Wood
Stress fractures in sport are becoming increasing more common, comprising up to 10% of all of sporting injuries. Around 90% of such injuries are located in the lower limb. This articles aims to define the optimal management of lower limb stress fractures in the athlete, with a view to maximise return rates and minimise return times to sport. Treatment planning of this condition is specific to the location of the injury. However, there remains a clear division of stress fractures by "high" and "low" risk. "Low risk" stress fractures are those with a low probability of fracture propagation, delayed union, or non-union, and so can be managed reliably with rest and exercise limitation...

H R Mohammad, J A'Court, A Pillai
Extruded talus is a rare serious result from a high-energy injury to a supinated and plantar flexed foot. Treatment remains controversial with a lack of congruent evidence for talar reimplantation. A 34-year-old woman was involved in a road traffic accident at 40 mph. Imaging revealed a left talus extruded anterolaterally with a talar neck fracture. Additional injuries included right acetabular fracture, transverse process fractures and rib fractures, which were treated conservatively. The talus was reimplanted and the talar neck fixed with a cortical screw...

Stress fractures of the foot and ankle are a commonly encountered problem among athletes and individuals participating in a wide range of activities. This illustrated review, the second of two parts, discusses site-specific etiological factors, imaging appearances, treatment options, and differential considerations of stress fractures of the foot and ankle. The imaging and clinical management of stress fractures of the foot and ankle are highly dependent on the specific location of the fracture, mechanical forces acting upon the injured site, vascular supply of the injured bone, and the proportion of trabecular to cortical bone at the site of injury...

Marian Dagosto, Daniel Gebo, Xijun Ni, Thierry Smith
Obtaining accurate estimations of the body mass of fossil primates has always been a subject of interest in paleoanthropology because mass is an important determinant for so many other aspects of biology, ecology, and life history. This paper focuses on the issues involved in attempting to reconstruct the mass of two early Eocene haplorhine primates, Teilhardina and Archicebus, which pose particular problems due to their small size and temporal and phylogenetic distance from extant primates. In addition to a ranking of variables from more to less useful, the effect of using models of varying taxonomic and size compositions is examined...

Scleraxis (Scx) is a basic helix-loop-helix transcription factor that is expressed persistently in tendons/ligaments, but transiently in entheseal cartilage. In this study, we generated a novel Scx(Cre) knock-in (KI) allele, by in-frame replacement of most of Scx exon 1 with Cre recombinase (Cre), to drive Cre expression using Scx promoter and to inactivate the endogenous Scx. Reflecting the intensity and duration of endogenous expression, Cre-mediated excision occurs in tendinous and ligamentous tissues persistently expressing Scx...

Chronic disruption of the extensor mechanism is a devastating problem after total knee arthroplasty. Quadriceps tendon ruptures occur at an estimated 0.1% prevalence in the setting of total knee arthroplasty. Complete tears of the quadriceps tendon generally have poor results and high rates of rerupture. We present a case of a quadriceps tendon rupture after total knee arthroplasty which reruptured after initial direct repair. The patient presented to us with a chronically retracted rerupture and was subsequently reconstructed successfully with a novel extended medial gastrocnemius-soleus-calcaneus local rotational pedicle flap...

Objective: The treatment of diabetic hindfoot ulcers is a challenging problem. In addition to serial surgical debridements, hyperbaric oxygen therapy and local wound care play important roles in the surgeon's armamentarium, for both superficial infection and gangrene of the soft tissue, often complicated by osteomyelitis of the calcaneus. The purpose of this study was to evaluate the results of an aggressive approach from diagnosis to treatment of calcaneal osteomyelitis in foot-threatening diabetic calcaneal ulcers...

Supplemental perioperative oxygen (SPO) therapy has been proposed as one approach for reducing the risk of surgical site infection (SSI). Current data are mixed regarding efficacy in decreasing SSI rates and hospital inpatient stays in general and few data exist for orthopaedic trauma patients. This study is a phase III, double-blind, prospective randomized clinical trial with a primary goal of assessing the efficacy of 2 different concentrations of perioperative oxygen in the prevention of SSIs in adults with tibial plateau, pilon (tibial plafond), or calcaneus fractures at higher risk of infection and definitively treated with plate and screw fixation...

When studying muscle and whole-body function in children with cerebral palsy (CP), knowledge about both internal and external moment arms is essential since they determine the mechanical advantage of a muscle over an external force. Here we asked if Achilles tendon moment arm (MAAT) length is different in children with CP and age-matched typically developing (TD) children, and if MAAT can be predicted from anthropometric measurements. Sixteen children with CP (age: 10y 7m±3y, 7 hemiplegia, 12 diplegia, GMFCS level: I (11) and II (8)) and twenty TD children (age: 10y 6m±3y) participated in this case-control study...

Jonathan Schiller, Steven DeFroda, Travis Blood
Lower extremity avulsion fractures are uncommon in the pediatric population and can be misdiagnosed without proper imaging and/or clinical suspicion for these injuries. The most common locations of avulsion injuries are the ischial tuberosity, anterior superior iliac spine, and anterior inferior iliac spine. Less often, avulsion fractures occur in the tibial tubercle, calcaneus, and greater and lesser trochanters. When treated properly with rest and altered weight bearing, most of these injuries heal without complication...

Discrete cystic or tumorous intraosseous lesions can arise from a variety of benign and malignant conditions as well as trauma and infection. They are clinically rarely observed in the calcaneus. A fourteen-to-seventeen-year-old subadult recovered from a Late Woodland (∼AD 800-1100) period mortuary context in the Mississippi River Valley of central Illinois presents with a single lytic intraosseous lesion on the posterior right calcaneus that bilaterally perforates the cortex. The lesion, although primarily anterior to the epiphyseal plate, does breach it...

BACKGROUND: The cementoma is a common disease of the dental root apex, which generally occurs in the maxilla and the mandible, but the cementoma occurring in the long bone is rare. Moreover, the incidence of cementoma in the calcaneus is extremely infrequent. CASE PRESENTATION: The present study reports an unusual case of a 19-year-old girl, who complained of pain in the left heel. Subsequent radiographs and computed tomography (CT) were used in the diagnosis. The imaging features of the lesion included a radiopaque matrix and radiolucent tissue, particularly an arc-shaped fat band...

OBJECTIVE: "Lisfranc joint injury" is comprised of a tarsometatarsal joint-complex injury. The Lisfranc complex injury is always a challenge for orthopedists, and the optimum treatment is still up for debate. Anatomic reduction and stable internal fixation prove to have no satisfactory outcomes. This research aims to compare the clinical curative effects, complications and radiographic features of arthrodesis and non-fusion of the Lisfranc joint in the follow-up of the patients who suffered Lisfranc injuries...

OBJECTIVE: To study and compare the clinical outcomes of open reduction and internal fixation via extensile L-shape incision and limited open reduction via the sinus tarsi approach using the medial distraction technique for intra-articular calcaneal fractures. METHODS: We performed a retrospective review of 65 intra-articular calcaneal fractures treated operatively between March 2012 and February 2015. Patients were divided into two groups: 28 were in the sinus tarsi approach group and 37 were in the extensile lateral approach group...

BACKGROUND: The accurate and reliable measurement of foot bone density is challenging and there is currently no gold standard technique. Such measurement is particularly valuable in populations at risk of foot bone pathology such as in those with long term diabetes. With research and development, computed tomography may prove to be a useful tool for this assessment. The aim of this study was to establish the reliability of a novel method of foot bone density measurement in people with diabetes using computed tomography...

OBJECTIVE: The mini-invasive technique, through a sinus tarsi approach (STA), has become an increasingly popular choice for the treatment of calcaneal fractures. However, despite the good results reported, the complications related with internal fixation have not yet been analyzed. Using 3D reconstruction CT scans, we proposed doing biometric description of the calcaneus with the purpose of performing osteosynthesis as treatment for calcaneal fractures. METHODS: A total of 24 CT scans were retrospectively obtained from 22 consecutive patients with healthy calcanei and no history of surgery or fracture...
