If one of your child's legs is longer than the other leg, he or she has a common problem known as leg length discrepancy. A typical difference in leg length can be anywhere from one centimeter, which usually does not cause any problems, to more than six centimeters. The greater the discrepancy, the more your child must compensate his or her normal posture and walking pattern in day to day life, which can lead to a variety of symptoms, such as functional scoliosis, hip, knee and ankle problems.

There are generally two kinds of leg length discrepancies:

Structural discrepancy occurs when either the thigh (femur) or shin (tibia) bone in one leg is actually shorter than the corresponding bone in the other leg. Functional discrepancy occurs when the leg lengths are equal, but symmetry is altered somewhere above the leg, which in turn disrupts the symmetry of the legs. For example, developmental dislocation of the hip (DDH) can cause a functional discrepancy. In DDH, the top of the leg bone (femur) that is not properly positioned in the hip socket may hang lower than the femur on the other side, giving the appearance and symptoms of a leg length discrepancy.

How Boston Children's Hospital approaches leg length discrepancy

Depending on the severity of your child's condition, doctors may or may not require surgery to treat the leg length discrepancy. But if the condition is severe enough to require surgery, doctors at Children's are committed to working with you and your child to weigh all the available options, taking into consideration recovery time, possible side effects and your child's individual physical needs.

Wireless networking

[返回上一页] [打 印]

         Wireless networking,, like so many things in life -- and especially the ones that have anything to do with computers -- is filled with jargon. Hi-tech babble baffles many Don't be intimidated, though: here's a quick computer-speak to English guide to help you out.

         802.11. The name of the wireless networking standard,, set by the IEEE. Ensures that wireless devices are interoperable.

         Driver. A piece of computer software that tells the computer how to talk to devices that are plugged into it. For wireless networking, the drivers you need to install will come on a CD with any equipment you buy.

         Ethernet. The most common way of connecting to a LAN. Any wires you might have connecting your computers together now are Ethernet wires, and the cable connecting your modem to your computer is probably an Ethernet wire too.

         Ghz. Gigahertz. A measurement of frequency -- one gigahertz is one billion cycles per second. You may recognise the measurement from computer processor speeds, which are now also measured in Ghz.

         IEEE. The Institute of Electrical and Electronics Engineers. In charge of the wireless networking standard,, as well as many other computer-related standards (including the Ethernet standard). They ensure that computer equipment made by different manufacturers can work together.

         Interoperable. Means that two pieces of equipment are compatible -- you can use them together,, because they stick to the standards. You should not get any wireless equipment that isn't interoperable.

         LAN. Local Area Network. A network that is generally confined to one building, such as a home or office. A wireless LAN is also known as a WLAN.

         Linux. An alternative operating system to Windows. Computers running Linux can run many programs and connect to the Internet without needing Windows. Linux is free to download and you are allowed to give it to friends to use. A lot of wireless devices run Linux, or are compatible with it.

         MAN. Metropolitan Area Network. A network that covers a larger area,, for example a town or city. Wireless MANs (men?) spread Internet access all over the area, but are expensive to set up. They are sometimes used on university campuses.

         Mbps. Megabits per second, a measurement of connection speed. Not to be confused with MBps,, megabytes per second. There are eight megabits in a megabyte.

         PAN. Personal Area Network. These are networks made up of devices connected together in one small area. For example,, your computer with a USB keyboard and mouse connected is a PAN. PANs can be wireless, using a technology called Bluetooth.

         PCI. Peripheral Component Interconnect. This is a way of installing new devices inside your computer, such as graphics cards and network devices. If you want to install a wireless card inside your computer, you will be using PCI.

         PCMCIA. Personal Computer Memory Card International Association (some say it should stand for 'People Can't Memorise Computer Industry Acronyms'). A standard for plugging credit card-sized devices into a laptop, to give it extra capabilities. PCMCIA is a great way of adding wireless networking to your laptop as easily as inserting a disk.

         USB. Universal Serial Bus. A port used for connecting all sorts of devices to a computer, including keyboards, mice, printers, external drives, and almost anything else you can think of. If you don't want to open up your computer and you don't have a laptop, you can get a USB wireless device.

         WAN. Wide Area Network. A network that is connected over more than one physical site, such as a business that has its computers in two countries connected on one network. The Internet,, for example, is a WAN -- the biggest WAN in the world.

         WEP. Wired Equivalent Privacy. The old standard for encrypting wireless networks. Unfortunately, it was found to be insecure back in 2001, and so should no longer be used.

         WPA. Wi-Fi Protected Access. Basically an upgrade of WEP to fix its security problems. WPA-encrypted networks change their encryption method often,, to avoid becoming vulnerable,, and also shut down for thirty seconds if they detect a suspected attack.

It could just be me

         It could just be me,, but my experiences with document collaboration remind me of a football game. It sounds crazy, I know, but working with a group and sending emails off to other members of the group caries with it that familiar uneasy sensation of Thanksgiving Day football games, where I often play quarterback and just as often wonder whether members of my family will catch the pass, and if they do, what they will do with the ball. Using groupware in document collaboration is similar to having a game plan that separates the ?urkey Bowl?family football team from the real competitors.

         Groupware on Three

         Now, this doesn? have to be the team cheer. But it could be, because groupware is distinguished from other document collaboration software by three characteristics designed to work the way businesses do. Since businesses frequently experience ad hoc document collaboration, groupware designed using Digital Thread,, Digital Signature, and Version History most effectively manages and controls ad hoc editing and keeps businesses informed.

         As a document manager, groupware helps businesses piece together the puzzle of ad hoc document collaboration. However,, when sifting through the millions of indexed pages under ?roupware?in any search engine, it is important to know what you are looking for. To that end, let me explain a little more of the ?roupware on Three?concept. Another helpful resource is my article Groupware: 3 Tips for Sifting Through Collaboration Suites.

         Digital Thread

         Business collaboration requires a lot of document sharing through email. Often document sharing creates a lot of confusion. Emails are being sent out, drafts are being edited, drafts are being saved in multiple locations, and changes are getting sent back to you out of order. Everything is jumbled up like a dog pile of lineman at the end of a play. The temptation at this point is to be a ball hog, and to run the ball ourselves. In football,, Steve Young could do it, but in business, nobody can. It just doesn? work.

         The Digital Thread literally threads document versions together, so that all of them are tracked and none of them get lost. Information is placed in the metadata of the document you are working on. This metadata is traceable and identifies various versions of documents,, changes made, and locations stored,, proving groupware to be an effective document manager.

         Digital Signature

         A Digital Signature opens up in emails sent and received, which displays the location of the most recent document and the version you are currently receiving. The Digital Signature takes the guesswork out of document collaboration.

         Version History

         As mentioned before,, document versions are sent back and forth throughout document collaboration; however, groupware that utilizes Version History creates and displays a flowchart of where the document has been and when it was there.

         Version History is an essential groupware tool, especially when merging time rolls around. Version History puts everything in its proper place in order to eradicate the normal confusion of ad hoc document collaboration.

         As a content management tool,, groupware utilizes these three tools not only to track the ad hoc collaboration but also to help piece the document back together again with simplified merging procedures.

         Unlike the Turkey Bowl,, collaboration with groupware will make a team play - even if it is ad hoc-successful.
