What is a pisiform excision?
Pisiform excision is a relatively safe procedure for patients with chronic ulnar-sided wrist pain due to pisotriquetral osteoarthritis, FCU tendinitis, or ulnar neuropathy when a conservative treatment is insufficient. Mixed diagnoses are often encountered in clinical practice.
Do you need pisiform bone?
Function. The pisiform serves as an attachment for tendons and ligaments. As it is a sesamoid bone, it acts as a pulley that provides a smooth surface for the flexor carpi ulnaris tendon to glide over. The pisiform also forms part of the ulnar canal or as otherwise called the Guyon canal.
Can you remove the pisiform bone?
Surgery is the only definitive treatment for persistent symptoms. The usual indication is pain and consequent functional difficulties. The operation involves removal of the pisiform bone. The function of the tendon is not altered by its removal.
What causes pain in the pisiform bone?
Pain in the area of the pisiform can be because of a wide variety of pathologies including tendinitis at the insertion FCU, arthritis of the pisotriquetral joint, subluxation of the pisiform with associated synovitis, fracture of the triquetrum or pisiform, rheumatism, or osteonecrosis.
Does everyone have a pisiform bone?
All other tetrapods have a pisiform, being the most common sesamoid. In mammals and non-human primates, the pisiform is an enlarged and elongated bone that articulates with the distal ulna. In some taxa, the pisiform even articulates with the hammate or radius.
What does a broken pisiform feel like?
This injury presents as chronic wrist pain, grip weakness, and/or restriction of wrist movements. Pisiform fractures may also be associated with tenderness in the affected area. Most pisiform fractures are a result of falling onto an outstretched hand (FOOSH injuries).
What is the bone sticking out of my wrist?
What is a carpal boss? A carpal boss, which is short for carpometacarpal boss, is an overgrowth of bone where your index or middle finger meets the carpal bones. Your carpal bones are eight small bones that make up your wrist. The condition is sometimes called carpal bossing.
What is the bone that sticks out of your wrist?
The pisiform bone (/ˈpaɪsɪfɔːrm/ or /ˈpɪzɪfɔːrm/), also spelled pisiforme (from the Latin pisifomis, pea-shaped), is a small knobbly, sesamoid bone that is found in the wrist. It forms the ulnar border of the carpal tunnel.
Can the Pisiform bone be removed?
Is the pisiform easy to break?
Pisiform fracture. Pisiform fractures are an uncommon injury accounting for only 0.2% of all carpal fractures. They are managed by immobilisation in either a plaster cast or a wrist splint. This fracture can be easily missed on first presentation due the superimposition of adjacent carpal bones.
What type of bone is pisiform?
The pisiform is the smallest of the carpals. Because it develops within a tendon, it is actually a sesamoid bone. There are other, much smaller sesamoid bones found embedded in flexor tendons, for example, at some metacarpophalangeal and interphalangeal joints.
What happens if you break your pisiform?
Pisiform fractures may be associated with triquetrum, hamate, or dorsal radius fractures. Clinical presentation includes pain, swelling, and tenderness of the hypothenar eminence. Ulnar nerve irritation may occur, because the pisiform makes up the ulnar wall of Guyon’s canal.
Why is my wrist bone getting bigger?
A carpal boss is an overgrowth of bone at your wrist. You may notice a hard bump on the back of your wrist. Sometimes, a carpal boss is mistaken for a ganglion cyst. Carpal bosses can cause pain similar to that of arthritis.

What is the function of the pisiform bone?
The pisiform bone may provide mechanical stability to the ulnar column of the wrist by preventing triquetral subluxation. Thus, surgical excision of the pisiform might cause loss of function to the wrist.
What happens when the piriformis muscle does not heal properly?
That is, the muscle is asked to do more than it is conditioned to do and it gives way, resulting in a chronic strain that cannot heal under its current load demands. The piriformis also takes a beating when the pelvis is not in its normal alignment, much like car tires wear abnormally when the alignment is off.
Is pisiformectomy for pisotriquetral joint dysfunction safe?
We conclude that pisiformectomy for pisotriquetral joint dysfunction can be safely recommended because restoration of function with a painless wrist is the normal outcome. MeSH terms
