PURPOSE: To review available approaches and fixation methods for posterolateral fracture fragment (PLF) in tibial plateau fracture, and to propose an algorithm to treat various types of plateau fractures which all involve the PLF. METHODS: This article reviews multiple surgical approaches for PLF and suggests an algorithm for suitable approach and fixation method according to PLF with combined plateau fracture. RESULTS: The modified anterolateral approach is a suitable single approach for fractures with a PLF combined with an anterolateral plateau fracture and for isolated posterolateral fracture fragments...

Despite the improvement of surgical techniques surgical site infections (SSIs) still remain a significant clinical burden in high risk patients undergoing osteosynthesis for tibia fractures. The use of an antibiotic coated implant might reduce the adhesion of bacteria on the implant surface and could therefore reduce the rate of implant-related infection or osteomyelitis. In this prospective multicenter study the use of a gentamicin-coated tibia nail for the treatment of open and closed tibia fractures and non-union revision cases was evaluated in 100 patients (99 treated) followed for 18 months...

BACKGROUND: The onset of inflammatory bowel disease (IBD) during childhood/adolescence compromises peak bone mass acquisition and predisposes to fractures later in life. However, the structural basis for bone fragility in young adults with IBD remains unknown. METHODS: One hundred two young subjects from the Swiss IBD cohort were included. Areal bone mineral density (aBMD) at distal radius, hip, and spine as well as morphometric vertebral fractures were assessed using dual-energy x-ray absorptiometry technique...

Genetic factors contribute to the risk of bone fractures, partly because of effects on bone strength. High-resolution peripheral quantitative computed tomography (HR-pQCT) estimates bone strength using micro-finite element analysis (µFEA). The goal of this study was to investigate if the bone failure load estimated by HR-pQCT-based µFEA is heritable and to what extent it shares genetic regulation with areal bone mineral density (aBMD). Bone microarchitecture was measured by HR-pQCT at the ultradistal tibia and ultradistal radius in adults from the Framingham Heart Study (n = 1087, mean age 72 years; 57% women)...

BACKGROUND: The classic metaphyseal lesion (CML) is strongly associated with infant abuse, but the biomechanics responsible for this injury have not been rigorously studied. Radiologic and CT-pathological correlates show that the distal tibial CML always involves the cortex near the subperiosteal bone collar, with variable extension of the fracture into the medullary cavity. Therefore, it is reasonable to assume that the primary site of bone failure is cortical, rather than intramedullary...

This review focuses on new developments and current controversies in the field of quantitative computed tomography. Recent positions of the International Society for Clinical Densitometry acknowledged the clinical value of quantitative computed tomography of the spine and the hip using clinical whole-body computed tomography (CT) scanners. Opportunistic screening summarizes a number of new approaches describing the dual use of clinical CT scans. For example, CT scans may have been taken for tumor diagnosis but may also be used for the prediction of high or low fracture risks as an additional benefit for the patient...

Lower rates of fracture in both Blacks compared to Whites, and men compared to women are not completely explained by differences in bone mineral density (BMD). Prior evidence suggests that more favorable cortical bone microarchitecture may contribute to reduced fracture rates in older Black compared to White women, however it is not known whether these differences are established in young adulthood or develop during aging. Moreover, prior studies using high-resolution pQCT (HR-pQCT) have reported outcomes from a fixed-scan location, which may confound sex- and race/ethnicity-related differences in bone structure...

Though still a topic of debate, the position that skeletal health is compromised with obesity has received support in the pediatric and adult literature. The limited data relating specifically to trabecular bone microarchitecture, however, have been relatively inconsistent. The aim of this pilot cross-sectional case-control study was to compare trabecular bone microarchitecture between obese (OB) and normal-weight (NW) late-adolescent females. A secondary aim was to compare diaphyseal cortical bone outcomes between these two groups...

In free-flap reconstruction of the lower extremity, due either to trauma or pre-existing vascular disease, healthy vessels may not be readily available in the proximity of the defect. A variety of options including a cross-leg free flap, vein grafts, arteriovenous loops, and "bridging" flaps have been used to address the issue. The purpose of this report is to present a case in which a 72-cm long extended bilateral deep inferior epigastric artery perforator (DIEP) free flap was used for coverage of a 20 × 25 cm soft tissue defect of the lower leg following a Gustilo grade IIIC fracture in a 29-year-old man...

In 1979, Pulsed electromagnetic fields (PEMFs) were approved by the Food and Drug Administration as an effective method in the treatment of non-unions. As well as PEMFs, also static magnetic fields (SMFs) have been widely investigated in orthopaedic studies. Even if the exact mechanism of action is not well understood, a large number of studies showed specific effects both at cellular and tissue levels. As bone fracture healing and osseointegration share the same biological events, the application of magnetic field stimulation in order to facilitate the osseointegration process has been suggested...

Tibial stress fractures are associated with increased lower extremity loading at initial foot-ground contact, reflected in high peak positive acceleration (>8g) of the tibia in adults. There is no reported data on peak positive acceleration of the tibia in children during walking and running. The aim of this study was to establish tibial peak positive acceleration responses in children across a range of age and gait speeds. Twenty-four children aged 8.5±1.4years with no known gait pathology comprised two age groups; Young (7-9year, n=12) and Older (10-12 years, n=12)...

Severe burn injury triggers massive alterations in stress hormone levels with a dose-dependent hypermetabolic status including increased bone resorption. This study evaluated bone microarchitecture measured by non-invasive high resolution peripheral quantitative computed tomography (HR-pQCT). Changes of serum bone turnover markers (BTM) as well as regulators of bone signaling pathways involved in skeletal health were assessed. Standardized effect sizes as a quantitative measure regarding the impact of serum changes and the prediction of these changes on bone microarchitecture were investigated...

Bone fracture risk increases with age, disease states, and with use of certain therapeutics, such as acid-suppressive drugs, steroids and high-dose bisphosphonates. Historically, investigations into factors that underlie bone fracture risk have focused on evaluation of bone mineral density (BMD). However, numerous studies have pointed to factors other than BMD that contribute to fragility, including changes in bone collagen and water. The goal of this study is to investigate the feasibility of using near infrared spectral imaging (NIRSI) to determine the spatial distribution and relative amount of water and organic components in whole cross-sections of bone, and to compare those results to those obtained using magnetic resonance imaging (MRI) methods...

The tibia is the most commonly fractured long bone. Tibia fractures are simple, and most are amenable to immediate closed reduction. Reported cases of irreducibility resulting from entrapment of soft-tissue structures are rare. We report the case of a 23-year-old man who, in a high-speed motor vehicle crash, sustained a closed lower leg fracture that was later found to have a unique pattern in which the fibula was entrapped in the medullary cavity of the tibia. Limited open reduction was performed, and the entrapped distal fibula was removed with use of a bone hook...
