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.

Mallet finger is a common injury involving either an extensor tendon rupture at its insertion or an avulsion fracture involving the insertion of the terminal extensor tendon. It is usually caused by a forceful blow to the tip of the finger causing sudden flexion or a hyperextension injury. Fracture at the dorsal aspect of the base of the distal phalanx is commonly associated with palmar subluxation of the distal phalanx. Most mallet finger injuries are recommended to be treated with immobilisation of the distal interphalangeal joint in extension by splints. There is no consensus on the type of splint and the duration of use. Most studies have shown comparable results with different splints. Surgical fixation is still indicated in certain conditions such as open injuries, avulsion fracture involving at least one third of the articular surface with or without palmar subluxation of the distal phalanx and also failed splinting treatment.

AbstractA 46-year-old man injured his ring finger and developed a mallet deformity. Radiographs showed a mallet finger fracture through an osteolytic lesion of the distal phalanx. Magnetic resonance imaging showed low intensity on T1-weighted imaging and high intensity on T2-weighted imaging, which suggested the clinical diagnosis of enchondroma. The bone tumor was excised, and osteosynthesis was performed using Ishiguro's extension block pinning, and a flexion block pin was added to prevent flexor tendon avulsion fracture through the enchondroma, followed by an autologous iliac cancellous bone graft. One year after surgery, the patient had no pain or extension lag of the affected ring finger, and his quickDASH score was 0 points. Radiographs showed no recurrence and minimal arthritic change of the distal interphalangeal joint. One-stage treatment of a mallet finger fracture through an enchondroma using Ishiguro's method was effective.

An unusual Salter type 2 fracture of the distal phalanx is described. The metaphyseal fragment of the fracture consisted of a long and thin plate of bone corresponding to the insertion site of the flexor digitorum profundus tendon. Differences between this combined fracture and the isolated mallet deformity or flexor profundus tendon avulsion fracture are discussed.

Background: The transfer of flexor-to-extensor is widely used to correct lesser toe deformity and joint instability. The flexor digitorum longus tendon (FDLT) is percutaneously transected at the distal end and then routed dorsally to the proximal phalanx. The transected tendon must have enough mobility and length for the transfer. The purpose of this study was to dissect the distal end of FDLT and identify the optimal technique to percutaneously release FDLT. Methods: Eight fresh adult forefoot specimens were dissected to describe the relationship between the tendon and the neurovascular bundle and measure the width and length of the distal end of FDLT. Another 7 specimens were used to create the percutaneous release model and test the strength required to pull out FDLT proximally. The tendons were randomly released at the base of the distal phalanx (BDP), the space of the distal interphalangeal joint (SDIP), and the neck of the middle phalanx (NMP). Results: At the distal interphalangeal (DIP) joint, the neurovascular bundle begins to migrate toward the center of the toe and branches off toward the center of the toe belly. The distal end of FDLT can be divided into 3 parts: the distal phalanx part (DPP), the capsule part (CP), and the middle phalanx part (MPP). There was a significant difference in width and length among the 3 parts. The strength required to pull out FDLT proximally was about 168, 96, and 20 N, respectively, for BDP, SDIP, and NMP. Conclusion: The distal end of FDLT can be anatomically described at 3 locations: DPP, CP, and MPP. The tight vinculum brevis and the distal capsule are strong enough to resist proximal retraction. Percutaneous release at NMP can be performed safely and effectively. Clinical Relevance: Percutaneous release at NMP can be performed safely and effectively during flexor-to-extensor transfer.
