Hemicondylar Hamate Replacement Arthroplasty for Proximal Interphalangeal Joint Fracture Dislocations: An Assessment of Graft Suitability

Hemi-Hamate Arthroplasty Provides Functional Reconstruction of Acute and Chronic Proximal Interphalangeal Fracture–Dislocations

“…In addition, although the distal hamate articular surface matches that of the middle phalanx well in the coronal plane, it has a much larger sagittal radius of curvature. 16 Therefore, it cannot be relied on to recreate the entire articular surface, but rather must be positioned canted toward the joint to restore the volar buttress. The results of hemi-hamate reconstructions for severe dorsal PIP joint fracture-dislocations are promising.…”

Biomechanical Characteristics of Hemi-Hamate Reconstruction Versus Volar Plate Arthroplasty in the Treatment of Dorsal Fracture Dislocations of the Proximal Interphalangeal Joint

“…4,7,12e16,20,21 Nearly all of the series using VPA were published more than 10 years ago and more recent reports demonstrate enthusiasm for performing hemi-hamate reconstructions. 4,7,13,14,16,20,21 No clear guidelines exist regarding which of these accepted treatments may be more appropriate given the characteristics of the injury. Our biomechanical data show that both VPA and hemi-hamate reconstructive options prevent dorsal subluxation of the middle phalanx, effectively restoring a concentric PIP joint.…”

Structural Comparison of the Finger Proximal Interphalangeal Joint Surfaces and Those of the Third Toe: Suitability for Joint Reconstruction

“…Efforts to characterize PIP joint morphology have included photographic analysis, 9 dental impression molding, 7 and radiographic analysis. 10 The current study developed a technique of laser surface scanning to both quantify toe articular dimensions and compare them to those of the fingers. The third toe was used in this comparison because it offers the potential for low donor site morbidity and reasonable size matching to the fingers.…”
