Hamate vs. capitate grafting for proximal interphalangeal joint fracture-dislocation: an MRI-based study of 35 hands.

J Hand Surg Eur Vol 2022 Jul 20;47(7):755-760. Epub 2022 Feb 20.

Orthopaedic Department, Tauranga Hospital, Tauranga, New Zealand.

We examined the MRI scans of 35 adult hands to assess the feasibility of the hamate and the capitate as potential donor grafts in the management of comminuted intra-articular fractures at the base of the middle phalanges. Essentially neither the hamate nor the capitate were perfect anatomic matches in most digits, but the capitate had the advantage of having more uniform facets, and the capitate facet shapes were similar to those of the little finger. The measurement of angles in the coronal and sagittal plane showed that in some respects the differences between the potential graft and the base of the middle phalanges were smaller for the capitate than for the hamate.

First reported case of a coronal hamate fracture associated with intrusion of the fifth metacarpal base, together with a fracture of the fourth metacarpal base.

BMJ Case Rep 2021 Sep 13;14(9). Epub 2021 Sep 13.

T&O, University of Perugia, Perugia, Italy.

We present a case reporting a rare combination of base of fourth metacarpal fracture and coronal body of hamate fracture, treated conservatively with excellent results. High index of suspicion for undetected bony injuries drove the execution of a CT scan, which allowed us to make a full correct diagnosis and plan treatment. Moreover, this case becomes the first reported case in the literature of such injury causing the intrusion of the base of the fifth metacarpal within the hamate bone, thus causing the coronal pattern of the hamate fracture.
