“…In a recent study, Allison (2005) has found the collateral ligaments of PIP joint to have wider attachments in both proximal and distal sides. In reconstruction of collateral ligaments of a PIP joint, the PIP PP of the joint may be used as the source of graft.…”

Palmar plates are being used as a source of graft in radial or ulnar collateral ligament reconstruction, pulley reconstruction, and volar plate arthroplasty. The purpose of this study is to determine morphometric and major histological differences of palmar plates in metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints among fingers, and supply sufficient data which would be useful in reconstruction procedures. Ninety-six MCP and 96 PIP palmar plates of 12 well-preserved formalin-fixed cadavers were measured focusing on their length, width, central thickness, and lateral thickness and statistically analyzed using ANOVA. Randomized three male and three female cadavers' specimens were examined histologically after staining with Masson's trichrome. For central thickness of the PIP joint level, there was significant difference among fingers, caused by the middle and little fingers. For lateral thickness of the PIP joint level, there was significant difference which was originated from little fingers. MCP palmar plates were significantly thicker than PIP joint levels for most of the fingers. There were thicker and denser collagen bands in MCP than PIP palmar plates. The relation of size-related parameters was not close with the thickness parameters. The predicted sizes and thicknesses of palmar plates vary according to fingers. The data collected for each finger in this study should be used as a guide in reconstructive procedures that use palmar plates as source of graft.

“…2,7,13,14,20 Some researchers also indicated that the accessory collateral ligament partially contributes to lateral stability. 7,13,14 The study by Minamikawa et al 14 reported that sectioning of the accessory collateral ligament and VP greatly increased lateral instability, especially when the joint was at midflexion and the extrinsic tendons were strained. In active flexion, when the VP moves volarward, it may well tighten the ligaments and provide dynamic lateral stability (Fig.…”

“…8,9,12 The VP may provide some lateral stability to the PIP joint. 2,7,13,14 Clinically, adhesion of the VP is one of the important factors causing a flexion contracture of the PIP joint. 10,11,[15][16][17][18] Releasing contractures of the VP and its supporting structures is a treatment option for the contracture; however, it may still be difficult to obtain a satisfactory surgical outcome.…”

“…Laterally , reinforcement is provided by the collateral ligaments which are 2-3 mm thick bands arising from a lateral fossa on the head of P1, running in a distal direction parallel to P2, to insert into the laterovolar tubercle at the base of the middle phalanx [ 34 ]. Due to the fi xed transverse axis, the length of these doesn't change in fl exion-extension.…”
