BackgroundTo evaluate the functional and radiographic outcomes, as well as the treatment costs, of closed displaced intra-articular distal radius fractures treated with either open reduction internal fixation (ORIF) with volar locking plates or nonoperative treatment with plaster cast immobilisation.Materials and methodsA total of 60 patients (32 receiving ORIF, 28 receiving nonoperative treatment) with closed intra-articular distal radius fractures were included. The mean age was 52.1 and 57.4, respectively. Functional and radiographic assessments were carried out at 12 months post-injury. Patients’ treatment costs, median salaries and lengths of medical leave were obtained.ResultsDASH and MAYO wrist score in the ORIF group did not differ significantly from those in the nonoperative group. Apart from superior ulnar deviation in the ORIF group (p = 0.0096), differences in the range of motion of the injured wrists were not significant. Similarly, there were no significant differences in grip strength and visual analog scale for pain. Volar tilt (p = 0.0399), radial height (p = 0.0087), radial inclination (p = 0.0051) and articular step-off (p = 0.0002) were all significantly superior in the ORIF group. There was a 37-fold difference in mean treatment costs between ORIF (SGD 7951.23) and nonoperative treatment (SGD 230.52).ConclusionOur study shows no difference in overall functional outcomes at 12 months for closed displaced intra-articular distal radius fractures treated with either ORIF with volar locking plates or plaster cast immobilisation, and this is independent of radiographic outcome. A longer follow-up, nevertheless, is needed to determine whether the development of post-traumatic arthritis will have an effect on function. The vast difference in treatment costs should be taken into consideration when deciding on the treatment option.Level of evidenceLevel 3.

Basal thumb arthritis is a common condition seen in hand clinics across the United Kingdom and is often associated with other pathological conditions such as carpal tunnel syndrome and scaphotrapezial arthritis. Typically, patients complain of pain localised to the base of the thumb. This pain is often activity related, particularly after excessive use involving forceful pinch. A detailed history and examination is normally all that is needed to make the diagnosis. Provocative manoeuvres may be helpful in localising symptoms to the basal joint with degenerative changes or synovitis. Radiographs are useful for confirming the diagnosis and staging the disease in order to plan for surgery. The mainstay of initial treatment of basal thumb arthritis of any stage is activity modifications, rest, nonsteroidal anti-inflammatory drugs, exercises and splinting. A variety of surgical procedures are available to treat the condition when conservative measures have failed, in order to control symptoms and improve function. We review the current literature and discuss the clinical aspects of this condition, staging, and treatment options available, and the difficulties treating this group of patients.

Bony mallet injuries are generally treated nonoperatively, but when the fragment involves a significant percentage of the articular surface, articular incongruity and instability can occur. A number of techniques have been described for the fixation of such fractures and each has its own problems. Anatomic reduction and secure fixation of small fragments can be challenging. Our objective is to describe a new surgical technique using a 1.3-mm hook plate that provides good reduction and stable fixation of a mallet fracture, with early mobilization of the distal interphalangeal joint.
