Webb1 jan. 2024 · The pisiform is a carpal bone of the proximal row embedded within the flexor carpi ulnaris (FCU) tendon. 2 Because of this location within the FCU, the pisiform is … Webb5 dec. 2016 · Previous biomechanical studies of the PT joint showed that the FCU, PML, and PHL were primary stabilizers of the pisiform against distal, proximal, and ulnar displacement, respectively [7, 9]. In the subgroup analysis of patients with distal radius fracture, the pisiform was located more toward the ulnar in the patients with PHL …
Long-Term Results of Pisiformectomy in a Cohort of 57 Patients
WebbThe pisiform is a small round, pea-shaped bone situated in palmar and ulnar aspect of wrist. Transverse carpal ligament and tendon of flexor carpi ulnaris have insertion on pisiform. FCU distally extends as pisohamate and pisometacarpal ligament. One theory considers pisiform as a sesamoid bone under FCU tendon.3 Webb12 jan. 2010 · Acute or chronic pain at the pisiform may be due to tendinopathy of the flexor carpi ulnaris tendon (FCU) insertion, mechanical overuse, bony fractures, and osteoarthritis of the pisiform-triquetral joint. Enthesiopathy of the FCU at the pisiform might exhibit abnormalities assessable for sonographic characterization. coffee 2d
Enthesiopathy of the flexor carpi ulnaris at the pisiform: Findings …
WebbFCU, tearing the pisohamate and/or pisometacarpal ligaments.3 The FCU is the wrist’s most powerful muscle, and the pisiform acts as a sesamoid, mechanically enhancing the action of the FCU.4 Therefore, the pull of this powerful muscle as well as the forced wrist hyperextension associated with a fall onto the outstretched hand cause a significant WebbExcision of the pisiform caused the FCU tendon to significantly retract during all wrist motions as compared to the intact wrist or after pisotriquetral arthrodesis. Conclusions: Greater FCU forces are required to move the wrist when the pisiform with its moment arm function has been removed. WebbThe primary stabilizers of the pisiform (P) are the flexor carpi ulnaris (FCU) tendon, pishohamate ligament (PHL), pisometacarpal ligament (PML), and the pisotriquetral … coffee 2d image
