[Purpose] The purpose of this study was to determine the relationships of changes in pain and gait after ischemia reperfusion was induced by tourniquet in rats. [Subjects and Methods] The subjects were six ten-week-old male Wistar rats. Ischemia was induced in the left lower limbs of the experimental rats at a pressure of 300 mmHg for 90 minutes. Pain behavior evaluations were measured using the von Frey test in all the rats' hind limbs. A consistently increasing plantar stimulus was applied until the rats exhibited an escape behavior...

BACKGROUND: Chronic noninsertional Achilles tendinosis can result in an acute Achilles tendon rupture with a short distal stump. In such tendon ruptures, there is a limited amount of adequate tissue that can hold suture, thus presenting a challenge for surgeons who elect to treat the rupture operatively. HYPOTHESIS: Adding suture anchors to the repair construct may result in biomechanically stronger repairs compared with a suture-only technique. STUDY DESIGN: Controlled laboratory study...

An open fracture of the calcaneus with loss of substance is a challenging injury and requires specialized care, involves high costs, and demands attention despite its lower incidence. The main complications are osteomyelitis, pressure ulcers, and fistulas, as well as pain conditions in the lateral, medial, and plantar regions. This is due to the wide loss of tissue and the change in anatomical conformation of the calcaneus in some cases. However, in cases of flattening of the calcaneus bone, these complications may be prevented or treated successfully...

OBJECTIVE: To evaluate the clinical results of surgical treatment of intraarticular fractures of the calcaneus, comparing the use of calcaneal plate and flat plate. METHODS: This was a retrospective study assessing the postoperative results of 25 patients between 2013 and 2015. Patients undergoing surgical treatment of intraarticular fractures of the calcaneus without concomitant surgical lesions were included. Patients who did not complete appropriate follow-up after surgery were excluded from the study...

BACKGROUND: Hindfoot alignment on 2D radiographs can present anatomical and operator-related bias. In this study, software designed for weightbearing computed tomography (WBCT) was used to calculate a new 3D biometric tool: the Foot and Ankle Offset (FAO). We described the distribution of FAO in a series of data sets from clinically normal, varus, and valgus cases, hypothesizing that FAO values would be significantly different in the 3 groups. METHODS: In this retrospective cohort study, 135 data sets (57 normal, 38 varus, 40 valgus) from WBCT (PedCAT; CurveBeam LLC, Warrington, PA) were obtained from a specialized foot and ankle unit...

REVIEW
Michael P Swords, Phillip Penny
The treatment of calcaneus fractures is controversial. Historically, most operatively treated fractures have been approached with a lateral extensile incision requiring delay in operative treatment until swelling has improved. There is a current trend and interest in small incision approaches allowing, and in some cases requiring, earlier operative fixation. Clinical scenarios amenable to consideration for early fixation are reviewed. The sinus tarsi surgical approach and reduction techniques are outlined in detail...

REVIEW
Michael P Clare, William S Crawford
Calcaneus fractures remain among the most complicated fractures for orthopedic surgeons to manage because of the complexity of various fracture patterns, the limited surrounding soft tissue envelope, and the prolonged rehabilitation issues impacting function after successful treatment. Despite this, appropriate management of complications associated with calcaneus fractures is critical for the complete care of this injury, whether treated operatively or nonoperatively. The authors present the common complications encountered with fractures of the calcaneus and management thereof...

OBJECTIVE: This study compares the cost and cost-effectiveness of treatments options for Sanders II/III displaced intra-articular calcaneus fractures (DIACF's) in laborers. METHODS: Literature on Sanders type II and III fractures was reviewed to determine complication rates and utility values for each treatment option. Costs were calculated using Medicare reimbursement and implant prices from our institution. Monte Carlo simulations were used to analyze a decision-tree to determine the cost and cost-effectiveness of each treatment from a societal perspective...

INTRODUCTION: Osteoprotegerin (OPG) is a powerful inhibitor of osteoclast activity, and it plays an important role in bone metabolism. In hemodialysis (HD) patients, the relationship between OPG and bone mineral density (BMD) is important, but remains unclear yet. The study objective was to assess the OPG role related to uremic osteoporosis in HD patients. METHODS: This cross-sectional study has been realized on a cohort of 63 chronic HD patients. INCLUSION CRITERIA: elderly prevalent HD patients with an age over 55 years old...

OBJECTIVES: The literature lacks comparative data regarding foot segmental mobility in rearfoot (RFS) and midfoot striking (MFS) patterns. The aim of the study is to quantify the foot segmental mobility during distinct subphases of stance in presence of both striking patterns. METHODS: Twelve participants were instructed to run barefoot at a constant speed of 3.3m/s on a 10-m walkway, while adopting a RFS and a MFS pattern. Multi-segment foot mobility during the impact phase, the absorption phase and the generation phase was subsequently calculated and compared between both conditions...

OBJECTIVE: Foot problems are often present in Systemic Sclerosis (SSc) patients, however studies regarding podiatric problems related to SSc are lacking and there are no data evaluating the foot biomechanical changes. The aim of the present pilot study was to evaluate podiatric problems in an Italian cohort of SSc patients by assessing received podiatric services, foot pain and disability and biomechanical foot deformity. MATERIAL AND METHODS: 25 consecutive SSc patients were enrolled from the Division of Rheumatology, University of Florence...

BACKGROUND: Overgrowth of the stump skeleton is a major complication seen in children after an amputation. In advanced cases, perforation of the bone spike through the skin can occur. Many surgical treatments have been employed to treat and prevent this, with best results seen when non-vascularised osteo-chondral bone grafts are placed to try to mimic a trans-articular amputation. We reviewed our outcomes using vascularized bone flaps to prevent and treat spiking. PATIENTS AND METHODS: Between 2000 and 2016 we carried out six vascularised osteo-cartilaginous bone capping procedures...

OBJECTIVE: Open treatment of calcaneus fractures often has an increased risk of wound healing. Minimally invasive treatment with small incisions reduces complications. INDICATIONS: Calcaneal fractures with malalignment/comminution >1-2 mm; broadening, varus alignment of the calcaneal length axis or shortening; emergency surgery for open fractures or compartment syndrome. CONTRAINDICATIONS: Local or general contraindications. SURGICAL TECHNIQUE: Standardised positioning; restoration of length/axis with 2‑point distractor under fluoroscopic control...

The purpose of this study was to determine the long-time and transient characteristics of the moment generated by external (ER) and internal (IR) rotation of the calcaneus with respect to the tibia. Two human cadaver legs were disarticulated at the knee joint while maintaining the connective tissue between the tibia and fibula. An axial rotation of 21° was applied to the proximal tibia to generate either ER or IR while the fibula was unconstrained and the calcaneus was permitted to translate in the transverse plane...

OBJECTIVE: To study the age and sex influence on bone and blood lead concentrations in a cohort of the general population living in Toronto. APPROACH: A (109)Cd K x-ray fluorescence (KXRF) measurement system was used from 2009 to 2011 in a study that measured the bone lead (Pb) concentration of 263 environmentally exposed individuals residing in Toronto, Ontario, Canada. Tibia (cortical bone) and calcaneus (trabecular bone) lead contents were measured in 134 males and 129 females between 1 and 82 years of age...

Osteomyelitis is an infectious process in bone that occasionally leads to bone destruction. Traditionally, the surgical treatment procedure is performed in combination with systemic and local antibiotics as a two-stage procedure that uses autograft or allograft bone for filling of the cavitary defect. Bioactive glass (BAG-S53P4) is a bone substitute with proven antibacterial and bone bonding properties.One hundred and sixteen patients who had verified chronic osteomyelitis was treated using BAG-S53P4 as part of the treatment...
