“…There is risk of injury to the central band and stiffness is often a consequence of the limited arc of motion. Nordback et al (2022) reported satisfactory clinical outcomes for extension block pinning with a mean arc of 80 in 33 cases at a mean follow-up of 16 years. They noted that 47% of patients had pain during activity, which could be related to arthritic changes.…”

Although proximal interphalangeal joint dislocations are generally straightforward to treat, fracture-dislocations are among the most difficult hand injuries to manage. Fracture patterns range from simple to treat palmar plate avulsion fractures to complex, unstable pilon fractures of the base of the middle phalanx, where achieving adequate reduction and fixation can be extremely difficult. Moreover, these fractures may present sub-acutely or chronically, which greatly adds to the complexity of the case. It is therefore no surprise that clinical results vary and are often difficult to predict. We will discuss the clinical presentations, the various dislocation and fracture-dislocation patterns, treatment options and the complications of these injuries.

“…Because of the high failure rate of conservative treatment, more and more surgeons are advocating early surgical intervention after injury. The most classic form of the procedure is the Ishiguro's method, which has been reported to be effective, but there are still some shortcomings, such as stiffness of joints and cartilage damage ( 1 , 2 ). So we modified the design of the method.…”

BackgroundThe bony mallet finger is a tear fracture of the extensor tendon, resulting in a flexion deformity of the finger, which affects both the function of the finger. The classical Ishiguro's method is associated with damage to the cartilage of the distal interphalangeal (DIP) joint and always lead to the joint stiffness. This paper explores a new technique to overcome the shortcomings of the classical Ishiguro's method and achieve better clinical efficacy.MethodsWe examined 15 patients with bony mallet fingers, 9 males and 6 females, from February 2020 to June 2022, ranged from 23 to 58 years, including 1 case of index finger, 5 cases of middle finger, 3 cases of ring finger and 6 cases of little finger. The median course of the injury to surgery was 2 days (range, 1∼7 days). All had fresh closed injuries, according to the Wehbe and Schneider classification: 4 cases of type IA, 6 cases of type IB, 3 cases of type IIA and 2 cases of type IIB. All patients were treated surgically by the new technique. Post-operative follow-up was conducted to record the healing of the fracture, the pain of the affected finger and the function of joint movement.ResultsThe 15 cases were followed up after surgery. The median active range of motion was 65° (range, 55∼75°). The median extension deficit of DIP joint was 0° (range, 0∼11°). The median clinical healing time of the fracture was 6 weeks (range, 6∼10 weeks). None of the patients experienced significant pain. The patients were assessed according to the Crawford criteria at the final follow-up: 11 cases were assessed as excellent, 3 cases were assessed as good and 1 case was assessed as fair. No loss of fracture repositioning, loosening of internal fixation, skin necrosis or infection was observed.ConclusionThe application of the new technique for the treatment of bony mallet fingers has the advantages of good stability, fracture healing and functional recovery of the DIP joint, making it an ideal surgical procedure for the treatment of fresh bony mallet fingers.
