Skier Tibia (Leg) Fractures
Skier Tibia (Leg) Fractures In years past, the prototypical ski fracture was sustained at the lower part of the outside of the leg in the region of the ankle. However, in the past 10 years, with the advent of the modern ski boots and improvements in binding, the most commonly seen lower leg skier fracture is the tibia (or shinbone) fracture. 10% of these fractures are associated with a collision. Thus, 90 % are associated with an isolated fall or noncontact type of injury, which is generally the result of binding malfunctions and inappropriate release. The most common mechanism leading to a tibia (leg) fracture is a forward fall. Risk factors for sustaining a skier tibia fracture include: beginners or novice skiers, less than 20 years of age, higher outdoor temperatures, and increased snow depth. Non-risk factors include ski lengths, icy conditions, and male versus female sex. The modern ski boot very closely resembles an extremely well padded short leg cast in the treatment of many orthopaedic lower extremity fractures. It of course goes to a much higher level than the former shorter boot top-level varieties. The binding release and designs have been based on the fracture strength of the adult tibia (shin) bone at the top of the modern ski boot. The treatment of most skier leg fractures includes a closed reduction and cast application for variable periods of time, with or without weight bearing allowed. However, severe misalignments of the bones can lead to later bony prominences that may be incompatible with snug, rigid, high fitting ski boots. -

Bones Can Tell Us More Compiled By: Nancy Volk Strong Bones Sometimes only a few bones are found in a location in an archeological dig. VOCABULARY A few bones can tell about the height of a person.

Normative Values for Femoral Length, Tibial Length, Andthe Femorotibial
Article Normative Values for Femoral Length, Tibial Length, and the Femorotibial Ratio in Adults Using Standing Full-Length Radiography Stuart A Aitken MaineGeneral Medical Center, 35 Medical Center Parkway, Augusta, ME 04330, USA; [email protected] Abstract: Knowledge of the normal length and skeletal proportions of the lower limb is required as part of the evaluation of limb length discrepancy. When measuring limb length, modern standing full-length digital radiographs confer a level of clinical accuracy interchangeable with that of CT imaging. This study reports a set of normative values for lower limb length using the standing full-length radiographs of 753 patients (61% male). Lower limb length, femoral length, tibial length, and the femorotibial ratio were measured in 1077 limbs. The reliability of the measurement method was tested using the intra-class correlation (ICC) of agreement between three observers. The mean length of 1077 lower limbs was 89.0 cm (range 70.2 to 103.9 cm). Mean femoral length was 50.0 cm (39.3 to 58.4 cm) and tibial length was 39.0 cm (30.8 to 46.5 cm). The median side-to-side difference was 0.4 cm (0.2 to 0.7, max 1.8 cm) between 324 paired limbs. The mean ratio of femoral length to tibial length for the study population was 1.28:1 (range 1.16 to 1.39). A moderately strong inverse linear relationship (r = −0.35, p < 0.001, Pearson’s) was identified between tibial length and the Citation: Aitken, S.A. Normative corresponding femorotibial ratio. -
Tibial De-Rotational Osteotomies for Tibial Torsion
Tibial De-Rotational Osteotomies for Tibial Torsion Why does my child need tibial torsion surgery? What happens during the surgery? A lot of young children walk with their toes pointing in or First, the surgeon cracks the tibia and the smaller fibula bone out instead of straight ahead. The most common reason is next to it, usually just above the ankle. Surgically cracking a tibial torsion, a twist in the tibia bone of the lower leg. This bone is also known as an osteotomy. It is similar to breaking twist brings the knee and ankle out of alignment. The feet a bone, except that it is done on purpose. The surgeon respond by turning in (internal tibia torsion) or out (external weakens the tibia bone first by drilling holes through a small tibia torsion). Most of the time, tibial torsion gets better as a surgical opening. The next step is to rotate, or turn, the bone child exercises the leg muscles by walking and running. into correct alignment. The surgeon then places a pin in the bone just below the knee. The pin will be removed once the But when a child has spasticity, a condition in which muscle bone heals. In the meantime, your child will wear a cast that tone is very strong, tibial torsion can get worse instead starts at the pin and covers the leg and foot. The cast keeps of better as the child grows. Surgery helps children with the leg from moving while new bone grows. spasticity who can stand, but cannot walk or run normally because of tibial torsion. -

The system allows for polyaxial screw placement (30°) with subsequent screw locking. Before locking, the screws can act as lag screws and be used for fracture reduction; a benefit which is not offered with standard locking systems. Implants are available with 2 or 3 proximal holes, left and right. Plate length In the locked mode, NCB PT Plate late varies from 5 to 9 shaft acts as an internal fixator without holes for the 2-proximal hole contact between the plate and the plate and between 3 and 13 shaft holes for the 3-proxi- bone surface reducing the risk of mal hole plate. -

BIOMECHANICS Anatomy Of The Foot And Ankle Multimedia Health Education Unit 1: Anatomy Introduction The foot and ankle in the human body work together to provide balance, stability, movement, and Propulsion. This complex anatomy consists of: 26 bones 33 joints Muscles Tendons Ligaments Blood vessels, nerves, and soft tissue In order to understand conditions that affect the foot and ankle, it is important to understand the normal anatomy of the foot and ankle. Ankle The ankle consists of three bones attached by muscles, tendons, and ligaments that connect the foot to the leg. In the lower leg are two bones called the tibia (shin bone) and the fibula. These bones articulate (connect) to the Talus or ankle bone at the tibiotalar joint (ankle joint) allowing the foot to move up and down. The bony protrusions that we can see and feel on the ankle are: Lateral Malleolus: this is the outer ankle bone formed by the distal end of the fibula. Medial Malleolus: this is the inner ankle bone formed by the distal end of the tibia. Tibia (shin bone) (Refer fig.1) Tibia -
