BACKGROUND:  The radial forearm free flap (RFFF) remains a workhorse flap but can have significant donor site morbidity. The authors developed a novel technique for endoscopic-assisted RFFF (ERFFF) harvest and hypothesized improved donor site morbidity. METHODS:  A retrospective cohort study was conducted evaluating patients who underwent ERFFF or RFFF by a single surgeon for head and neck reconstruction between November 2011 and July 2016; outcomes and complications were compared...

PURPOSE: A simple overlay device (SOD) was developed to measure radial head implant length. The purpose of this study was to determine the accuracy and reliability of this device for measuring experimental radial head implant length. METHODS: Five fresh frozen cadavers were implanted with sequentially longer implants, adjusted by neck length (0, 2, 4, and 8 mm). Fluoroscopic images were obtained in 4 forearm positions: anteroposterior in supination in full extension, anteroposterior in pronation in full extension, supinated in 45° of flexion, and neutral in 45° of flexion...

Arterial stiffness is a reliable prognostic parameter for cardiovascular diseases. The effect of change in arterial stiffness can be measured by the change of the pulse wave velocity (PWV). The Complior system is widely used to measure PWV between the carotid and radial arteries by means of piezoelectric clips placed around the neck and the wrist. The Biopac system is an easier to use alternative that uses ECG and simple optical sensors to measure the PWV between the heart and the fingertips, and thus extends a bit more to the peripheral vasculature compared to the Complior system...

Radial forearm free flaps (RFFF) are the "workhorse" of reconstructive head and neck surgery, but have considerable morbidity at the donor site. The aim of this study was to review current publications about the incidence and type of morbidity and the different techniques used for closure of the site. We screened the MEDLINE database to find relevant papers using the terms "RFFF head and neck" and "RFFF donor site". Abstracts were filtered, and the full texts studied carefully...

OBJECTIVES: To quantitate differences between cases of hip fracture and controls in cortical width around the mid-femoral neck in men and women. METHODS: Over 5 years, 64 (14 male) participants over age 55 (mean 79) years, who had never taken bone-active drugs and suffered intra-capsular hip fracture treated by arthroplasty, donated their routinely discarded distal intra-capsular femoral neck bone for histomorphometry. After embedding, complete femoral neck cross sections from the cut surface near the narrowest part of the neck were stained with von Kossa and cortical width was measured radially every 5 degrees of arc...

Posttraumatic proximal radioulnar synostosis (PPRUS) is a severe complication of radial head and neck fractures known to occur after severe injury or operative fixation. Cases of PPRUS occurring after minimally displaced, nonoperatively treated radial neck injuries are, by contrast, extremely rare. Here, we present a pediatric case of PPRUS that developed after a nonoperatively treated minimally displaced radial neck fracture with concomitant olecranon fracture. While more cases are needed to establish the association between this pattern of injury and PPRUS, we recommend that when encountering patients with a minimally displaced radial neck fracture and a concomitant elbow injury, the rare possibility of developing proximal radioulnar synostosis should be considered...

Forward head posture (FHP) is one of the most frequently seen problems. The aim of this study was to evaluate the neurodynamic tests and peripheral nerve conductions of upper extremity in patients with FHP. The study population included 100 patients with upper extremity and neck problems and 34 healthy individuals as a control group. Craniovertebral angle measurement was used to determine forward head posture. Stretch tests for radial, ulnar and median nerves were performed. Nerve conductions of bilateral median, radial, ulnar and medial antebrachial cutaneous (MAC) nerves were examined in all patients included in the study...

BACKGROUND: Mechanical loading improves bone mineral density (BMD) and strength while decreasing fracture risk. Cross-sectional studies show that exercise advantage is lost in oligo-amenorrheic athletes (OA). Longitudinal studies examining the opposing effects of exercise and hypogonadism on bone are lacking in adolescents/young adults. OBJECTIVE: Evaluate differences in bone accrual over 12 months in OA, eumenorrheic athletes (EA) and non-athletes (NA). We hypothesized that bone accrual would be lower in OA than EA and NA, with differences most pronounced at non-weight bearing trabecular sites...

Background & aims: Altered lung function and consequent decrease in oxygenation has been linked to the duration of anaesthesia. This necessitates oxygen monitoring and supplementation in the perioperative period. But, evidence is lacking regarding the parameter that guides best the oxygen supplementation in the postoperative period and the parameter that correlates best with the duration of anaesthesia. Methods: Adult patients scheduled for head & neck surgery under general anaesthesia were recruited...

AIM: Regional anesthesia with ultrasound-guidance is an excellent option for pain control if nerves are adequately visualized. Gender, body mass index (BMI), history of diabetes, neck and forearm circumference may affect echotexture and visualization. This study evaluates patient characteristics for their ability to predict the echogenicity or visibility of upper extremity peripheral nerves. MATERIAL AND METHODS: This is a prospective observational study. A convenience sample of adult emergency department patients were enrolled...

Human cortical bone fracture processes depend on the internal porosity network down to the lacunar length scale. Recent results show that at the collagen scale, the maturation of collagen cross-links may have a negative influence on bone mechanical behavior. While the effect of pentosidine on human cortical bone toughness has been studied, the influence of mature and immature enzymatic cross-links has only been studied in relation to strength and work of fracture. Moreover, these relationships have not been studied on different paired anatomical locations...

Radial head and neck fractures are one of the most common elbow fractures, comprising 2% to 5% of all fractures, and 30% of elbow fractures. Although uncomplicated Mason type I fractures can be managed nonsurgically, Mason type II-IV fractures require additional intervention. Mason type II-III fractures with 3 or fewer fragments are typically treated with open reduction and internal fixation using 2 to 3 lag screws. Transverse radial neck involvement or axial instability with screw-only fixation has historically required the additional use of a mini fragment T-plate or locking proximal radius plate...

Aims Asphericity of the femoral head-neck junction is common in cam-type femoroacetabular impingement (FAI) and usually quantified using the alpha angle on radiographs or MRI. The aim of this study was to determine the natural alpha angle in a large cohort of patients by continuous circumferential analysis with CT. Methods CT scans of 1312 femurs of 656 patients were analyzed in this cross-sectional study. There were 362 men and 294 women. Their mean age was 61.2 years (18 to 93). All scans had been performed for reasons other than hip disease...
