The problems with Fixed Volume Ischial Weight Bearing Sockets have one thing in common.
Patient feedbacks vary, but essentially they’re all about the same issue. Socket volume.
- Ischial discomfort or pain
- Anterior wall impingement in sitting
- Request lowering the anterior trim line
- Request modify ischial containment
- Complain the socket tore clothes
- Complain that the socket is too bulky
- Complain too hot
Our ActivFIT socket is designed to solve all these frequently experienced issues with socket volume.

The roll at the top of the ActivFIT CJ Sail becomes uncomfortable in sitting. What can be done?If the roll at the top of the ActivFIT CJ Sail becomes uncomfortable, you can partially or fully remove the felt roll. Please call (978) 922-0413 for instructions.
My patient is complaining of groin pain.The ischium should not contact the rigid socket. Make sure your medial wall does to extend posterior to the adductor longus. Check for proper rotation on donning. Make sure the medial wall angles out (medially/ towards the midline) to transition to the Sail’s splay. Your socket may be too deep. Your ML may be too wide.
The ActivFIT CJ Sail seems too low below the gluteal fold.If the limb is very conical, or the socket requires significant flexion, the ActivFIT CJ Sail can be made with an arc shape to raise up the proximal edge.
The patient cannot snug the ActivFIT CJ Sail effectively.In cases of poor arm strength, the sail can be made with chaff loops on the batten. This will provide a 2:1 pull and reduce the required strength by 50%. In cases of poor finger strength, sewing large Dacron loops on the closure straps can be helpful.
The ActivFIT CJ Socket feels heavy or causes pins and needles (paresthesia)The closure may be pulled too tightly. Make sure it is soft in non-weight bearing. In cases of extreme ischemia, the ActivFIT CJ Sail can be left loose while sitting and snugged only when needed to ambulate.
The batten on the ActivFIT CJ Sail is pulled over and onto the rigid socket adductor longus area.Your socket is out of volume adjustment. Ideally the batten should be between .5 to 1.25 inches posterior to the rigid socket trim line. The Sail should cover half the residual limb and follow a normal shape. Socks and pads may be used to decrease socket volume. Consider a new socket.
The 1:1 Velcro closure on the ActivFIT CJ Sail wears out too fast.The 1:1 Velcro is under too much tension. Consider a 2:1 Loop attached to batten closure. Consider a 1" pressure buckle + 1" Loop closure and eliminate the Velcro.
The ActivFIT CJ Socket rotates externally at heel strike.The Scarpa’s modification may be too aggressive. Check for excessive toe out. Use a proximal suspension aid i.e., Coyote, Kiss or a small Velcro strip attached to the gel insert. There are times when with any socket, soft, fleshy or short limbs just need a belt.
Keith Cornell’s new socket design at #OPWorldCongress is intriguing. May combine the best of ischial containment and flexible sockets, with fewer of the drawbacks of either.
One of the two new socket designs now being offered for above knee amputees. This design is called the CJ Socket and offers amazing improvements in comfort and adjustability. Set up an appointment today to find out if this is a good option for you.
Pat Peick, CPO
Thank you for inventing the CJ Socket and making it available to the Prosthetist’s toolbox. I attended your excellent one day seminar which was one of the best I have ever attended for depth of knowledge and completeness of any new technique. There will be many amputees across the country who will smile many more times in the day due to the CJ Socket. I truly liked the seminar and the technique, and you have a naturally educational demeanor.
Meet Joey Z, the amputee. Take two minutes to hear his inspirational story.
