“…Little has been written about mallet fractures of the thumb. 3,9,14 In this study, we compared mallet fractures of the thumb with mallet fractures of other fingers and found that mallet fractures of the thumb generally present for treatment earlier and are not associated with subluxation.…”

“…3,14 There are few reports about mallet thumbs, particularly those with associated fracture. 3,9,14 Little is known about the difference between mallet fractures of the thumb compared with mallet fractures of the index through small fingers with respect to etiology, radiographic findings, and treatment. They are seemingly less common, perhaps due to shorter length and greater size of the thumb.…”

Background: The purpose of this study was to look for differences in mechanism, radiographic findings, and treatment between mallet fractures of the thumb and mallet fractures of the index through small fingers. Methods: This retrospective study included 24 mallet fractures of the thumb and 392 mallet fractures of other digits. We compared demographics, injury factors (side, dominant hand, time between injury and first visit, and injury mechanism), subluxation, fragment size, treatment, and time from injury to final evaluation between the 2 groups. Results: Mallet fractures of the thumb presented for treatment sooner after injury (2.9 vs 13 days on average), had less fragment displacement (27% vs 33%), and less articular involvement (39% vs 46% on average). None of the mallet fractures of the thumb had radiographic evidence of subluxation, whereas 25% of mallet fractures of other fingers had initial or later subluxation. Conclusions: Mallet fractures of the thumb are not likely to subluxate.

“…The surgical options for bony mallet thumb include tension band fixation, compression fixation pins, and the extension block technique [2–4]. Teoh and Lee and Theivendran et al have described the use of the hook plate technique for bony mallet finger, but not bony mallet thumb, to obtain anatomical reduction and stable fixation with early mobilization [8, 9].…”

“…Mallet finger is a common sport injury, but bony mallet thumb is rarely encountered because the thumb is shorter than the other fingers and the extensor pollicis longus (EPL) is thicker than the other extensors [1]. It is reported that bony mallet thumb has been managed by tension band fixation, compression fixation pins, or the extension block technique [2–4]. The anatomical reduction, rigid fixation, early resumption of motion activity, and early return to the work offered by the hook plate technique for bony mallet finger have not previously been reported in bony mallet thumb injuries, so far as we know.…”

Bony mallet is a common sport injury, but bony mallet thumb is rarely encountered. We performed open reduction and fixation of bony mallet thumb using a hook plate procedure on a 27-year-old man under general anesthesia. The patient began working one day after surgery. Six months postoperatively, the patient had excellent dexterity according to Crawford's evaluation criteria and no difficulties at work or playing softball. Tension band fixation, compression pins, and the extension block technique are commonly used to manage bony mallet. Despite the anatomical reduction, rigid fixation, and early resumption of motion skills offered by the hook plate technique, to our knowledge, no previous reports of its application to bony mallet thumb were found. In this case, the hook plate technique was chosen and made an early return to work possible and brought about a successful result.

“…A series by Robb included mallet deformity of 149 digits, only one of which was a mallet thumb [ 5 ], and a series by Wehbe and Schneider included only one mallet thumb among mallet fractures of 160 digits [ 2 ]. The thumb is shorter than the fingers and the extensor pollicis longus (EPL) is thicker than the extensors of the fingers, which could be one of the reasons for the rarity of EPL avulsion or laceration [ 6 ].…”

Mallet fingers with an avulsion fracture of the distal phalanx or rupture of the terminal tendon of the extensor mechanism is known as a common injury, while mallet thumb is very rare. In this paper, the case of a 19-year-old woman with a sprained left thumb sustained while playing basketball is presented. Plain radiographs and computed tomography revealed an avulsion fracture involving more than half of the articular surface at the base of the distal phalanx. Closed reduction and percutaneous fixation were performed using the two extension block Kirschner wires' technique under digital block anesthesia. At 4 months postoperatively, the patient had achieved excellent results according to Crawford's evaluation criteria and had no difficulties in working or playing basketball. Various conservative and operative treatment strategies have been reported for management of mallet thumb. We chose the two extension block Kirschner wires' technique to minimize invasion of the extensor mechanism and nail bed and to stabilize the large fracture fragment.
