Prosthetic & Orthotic Advancements

Microprocessor Prosthetic Knees
 While there are a many different styles of knees available for use with an above knee prosthesis the microprocessor knees utilize the newest technology and enables patients to walk to with the highest degree of mobility and confidence.  These knees are designed to allow the practitioner to program them with a laptop computer and match the patients specific gait characteristics. They constantly tracking their position in space (50-1000 times a second) by recieveing information from internal sensors and determining when the foot is on the ground and when it is swinging forward. This allows the knee to constantly adjust for the proper amount of resistance it needs. 
In other words, it knows when a patient is picking up their leg and allows it to swing forward with ease, but will create resistance so it will not buckle if stumbling occurs. Our prosthetists at Oregon Orthotic Services, Inc. are certified to fit both the C-Leg and RHEO knees which are the most recent microprocessor knees to be available for amputees.

MAS Above Knee Socket design (Marlo Anatomical Socket)
 There are several different styles of Ischial Containment" socket designs that a practitioner may choose from when building an above knee prosthesis. The most recent was developed by Marlo Ortiz, C.P. from Jalisco, Mexico and is termed the "MAS" socket. Mr. Ortiz has shared his design with the practitioners of the prosthetic community to the benefit of all above knee amputees. This socket design utilizes a three force vector system
 to stabilize the pelvis and allow for lower and more cosmetically apealing trim lines as compared to traditional socket designs. Other features include comfotable sitting positioning, ease of donning and an increased range of motion. Suspension choices with this design may use traditional as well advanced methods. Our practitioners at Oregon Orthotic Services, Inc. have been trianed in this method of socket design and are currently providing the design for their patients.

Vacuum suspension
 The newest form of suspension is the vacuum suspension. Our company is currently using the e-Vac vacuum system that utilizes this technology. This form of suspension is advantagous for those patients who experiance frequent volume loss throughout the day, perspire excessivly and are in need of a extremely reliable form of suspension for their prosthesis. With the use of this technology we can control volume loss, excessive perspiration and provide patients a more intimate, "lighter feeling" fit and increased function as a result. Patients using the e-Vac system love the sense of freedom it provides.

Stance Control KAFO Knee Joints
Some people need the stability of a locked knee when they are standing and walking on their affected leg, A locked knee makes it much harder to clear the leg over the ground as advance their leg when walking.
Some of these people are perfect candidates for what is called Stance Control KAFOs.  These devices, through a few different types of joint mechanisms, create a locked knee when the leg is supporting the weight of the body but unlock when the leg is lifted to allow for easy advancement of the leg as it is allowed to bend.  For the right patients, this allows them as much mobility to get around as it does stability.


 Back to learn about O&P

The latest in vacuum suspension technology is LimbLogic VS. This is the first remote-controlled vacuum suspension system on the market. The 4-Hole Controller is mounted inline on a prosthesis allowing for complete integration without the annoyances of tubes into the socket or the unit catching on clothing.

LimbLogic VS operates quietly and features 'Set & Forget' monitoring. This means that the system monitors the level of vacuum pressure in the socket to maintain a secure and comfortable fit. Our practitioners program LimbLogic VS for a set range of vacuum. The amputee may use the fob to adjust the vacuum level within the practitioner-set range.
