Coronal fractures of the body of the hamate: Two case reports
نویسنده
چکیده
Fractures of the hamate were classified by Milch (1) into body fractures and hook fractures; fractures of the body of the hamate were subdivided into those occurring on the radial side and those occurring on the ulnar side of the hook. Bowen (2) presented a hamate fracture in the coronal plane and, therefore, added a third category – fractures to the body of the hamate. The two cases described in this report are examples of this rare type of fracture; both were associated with disarticulations at the base of the fourth and fifth metacarpals. Open reduction and internal fixation led to rapid recovery in terms of stabilization of the hamatometacarpal joint and restoration of hand function.

The Prevalence of Unanticipated Hamate Hook Abnormalities in Computed Tomography Scans: A Retrospective Study
Background:It is possible that some hamate hook fractures are not diagnosed or treated, thereby affecting the study of their natural history. Study of the prevalence of incidental hamate hook fractures, nonunions, and other abnormalities on computed tomography (CT) ordered for another reason could document a subset of undiagnosed and untreated hamate hook fractures which might change our under...

Background: The hemi-hamate arthroplasty (HHA) can restore joint congruity and stability in chronic fracturedislocationsof the proximal interphalangeal joint (PIPJ). Purpose of this study was to compare the width of the distalhamate articular surface (DHAS) to the width of the base of the middle phalanges (P2) of the fingers. We hypothesizedthe dimensions of the width of the D...
متن کاملTreatment of horizontal root fracture with extrusion: A case report
Root fractures are defined as fractures involving dentine, cementum, and pulpal and supportive tissues. They comprise about 0.5–7% of all dental injuries. Horizontal root fractures are commonly observed in the maxillary anterior region and 75% of these fractures occur in the maxillary central incisors. Case report: This case report is about a 26-year-old male referred to the endodontic departme...
متن کاملFracture of the Body of the Hamate With Dorsal Dislocation of the 4th and 5th Metacarpals: A Case Report
BACKGROUND Solitary fractures of the body of the hamate are rare. Their diagnosis is difficult and requires a high clinical suspicion and a proper radiological examination. CASE REPORT We present a case of a 36-year-old male patient who sustained an intraarticular fracture of the body of the hamate along with dorsal dislocation of the 4th and 5th metacarpals on his right dominant hand. Throug...
متن کاملDelayed Repositioning in Teeth with Horizontal Root Fracture: Two Case Reports
Introduction: Horizontal root fracture (HRF) generally has a good prognosis of healing at fracture line after repositioning and flexible splinting. However, various factors such as delayed referral may unfavorably influence close reduction of firmly displaced coronal fragments and the long-term prognosis of healing at fracture line. Case 1: A 25-year-old woman with HRF in her maxillary central ...
