Common Problems with Fixed Volume Ischial Weight Bearing Sockets

  • Patient complained of groin / ischial discomfort or pain
  • Patient complained of anterior wall impingement in sitting
  • Patient insisted you lower anterior trim line
  • Patient insisted you lower ischial containment modifications
  • Patient complained that socket tore their clothes and/or marked their furniture
  • Patient developed adductor rolls
  • Patient complained that the socket is too hard to donn, too bulky, too cumbersome or too hot
  • Socket caused pain, bruising, skin irritation or breakdown
  • Socket no longer fits properly due to volume changes in residual limb

In short, controlling socket volume is everything and ironically heretofore, not addressed in socket design.

Why CJ Socket Is The Solution

The CJ Socket was designed to address residual limb volume change (RLVC). By simply adjusting the closure, the CJ Socket allows the patient to easily maintain a precise volumetric fit and avoid issues with weight bearing and skeletal control.  The CJ Socket also dramatically improves comfort and by extension, the patient’s wearing time and overall success.

  • Accommodates residual limb volume change and maintains precise volumetric fit

  • Hydrostatic-only weight bearing for Above the Knee and Below the Knee – eliminates ischial pressure

  • Allows FULL ROM – eliminates ischial extension stop

  • Minimizes motion in socket – patient has the ability to adjust the socket and maintain an exact volumetric fit

  • Patients report significant increases in comfort

  • Adjustability can increase socket useful lifetime

Moreover, because the CJ Sail is a textile, it conforms to the seat allowing the AP of the socket to decrease and the thigh to splay more naturally.  And because the AP is reduced in sitting, the anterior trimline of the socket maintains its intended position and closely follows the inguinal ligament thereby reducing impingement on the abdomen.

For any prosthesis to be successful, the patient has to want to wear their socket!

How The CJ Socket Works

CJ Socket Prosthetic Components

The Right Tools. The Right Solution.

With the design of the CJ Socket, we have introduced a novel departure from conventional rigid or semi-rigid solid sockets that allows the patient to adjust the closure and maintain a precise fit without the need for a new solid socket to be made.  The CJ Socket is comprised of 3 main parts:

  • a rigid J-shaped frame,
  • a non-elastic garment referred to as the Sail, and
  • a patient-adjustable Closure.

CJ Socket Rigid J SocketThe J-shaped Socket

The rigid J-shaped socket covers approximately 50% of the residual limb. It transfers the skeletal (femoral/tibial) forces from the residual limb to the prosthesis providing skeletal control. Typically, a transfemoral frame covers the residual limb from the adductor longus muscle extending anteriorly and laterally to the posterior edge of the femur.

  • Rigid support is only where it’s needed
  • For Above Knee and Below Knew, the back half is left open.
  • Half the weight, half the heat, half the hassle.

CJ Socket Prosthetic Leg FabricationThe Sail

The Sail comfortably contains the remainder for the residual limb. The posterior and medial tissues are contained by this non-elastic, flexible inner socket/garment. The Sail serves to provide unprecedented flexibility and comfort. It allows the socket’s AP and diagonal ML to be dynamic, and for the socket to take various shapes for sitting or standing.

  • This is the flexible non-elastic textile which completes the socket enclosure of the residual limb.
  • More like clothing than a plastic socket.
  • Unprecedented comfort.

CJ Socket Prosthetic ComponentsThe User-adjustable Closure

The User-adjustable Closure ensures that the socket volume is precise to provide optimal hydrostatic lift and skeletal control. The closure allows the user to adjust the socket and accommodate residual limb volume changes (RLVC) easily and quickly.

  • The patient controls the fit of the socket!
  • The volumetric fit is always precise.
  • The closure easily accommodates changes in size and volume.
