Johnson et al. (2013) found that morphometric measurements of dragonfly wings taken from actual specimens and measurements taken from whole-drawer images of those specimens were equally accurate. We do not believe that their conclusions are justified by their data and analysis. Our reasons are, first, that their study was constrained in ways that restrict the generalisability of their results, ...

Nine children who were less than fourteen years old and had open physes and ligament injuries of the knee were studied. Despite an initial thorough physical and roentgenographic evaluation, the full extent of the lesion was determined only at operation in seven of the nine patients. The intercondylar eminence of the tibia was avulsed in five patients, four of whom had associated collateral liga...

Introduction Bone-patella tendon-bone (BPTB) grafts are widely used for anterior cruciate ligament (ACL) reconstruction. Experimental data have demonstrated that these grafts are almost 3 times stiffer than the ACL. (1,2) While many in-vivo and in-vitro data demonstrated that the ACL reconstruction is efficient in restoring anterior stability using anterior drawer tests, recent in-vivo measurem...

The lateral substitution reconstruction operation described by MacIntosh has been evaluated in 27 patients with chronic anterior cruciate ligament deficiency of the knee. The results, at an average of 11.3 years after operation, have been assessed by a scoring system which allocates a maximum of 25 points each for function and for clinical evaluation. Emphasis was placed on subjective giving wa...

Many studies show the close relationship that exists between text and illustration. In case of travel literature, this is much closer, because for most authors type illustration as necessary to convey reader wonderful reality they have experienced far home. On many occasions it was writer who illustrated book, but on others commissioned work a professional illustrator. The Louisa Tenison catche...

The Tibial Tuberosity Advancement (TTA) surgical technique is used in veterinary surgery to limit cranial tibial translation during canine gait, lengthening the lever arm of quadriceps Anterior Cruciate Ligament-deficient (ACL-deficient) stifle joints. It know that after TTA, patellofemoral pressure decreases, but Patellar Tendon (PT) behavior has not been observed experimentally yet. This stud...

STUDY DESIGN Prospective, blinded, diagnostic-accuracy study. OBJECTIVES To investigate the diagnostic accuracy of the ankle anterior drawer test (ADT) to detect anterior talocrural joint laxity in adults with a history of lateral ankle sprain. BACKGROUND The ADT is used to manually detect anterior talocrural joint laxity following lateral ankle sprain injury; however, the diagnostic accura...

The search for novel methods to record excavated features in archaeological sites has led to the invention or adaptation of many technological tools, ranging from photogrammetry to 3D reconstruction. Unfortunately, many of these methods require more training, more preparation and more expense than the traditional method of handing a measuring tape, plumb bob and graph paper to a volunteer. Whil...

BACKGROUND The knee joint is vulnerable to various injuries and degenerative conditions, potentially leading to functional instability. Usual treatments involve knee orthoses to support the joint. However, the level of mechanical action of these devices remains controversial despite high prescription and demand. METHODS The mechanical ability of three commercial hinged knee braces and one sle...
