Purpose of the study: We report our experience with the LCP DRP 2.4 plate with a locking screw for the treatment of distal factures of the radius.

Material and methods: Between 2003 and June 2004, 67 displaced fractures of the distal radius were treated with a LCP DRP 2.4 system. Patients were subsequently immobilized in a removable anatomic orthesis for three weeks. The Fernandez, Castaign and AO classifications were used. Clinical evaluation was based on the DASH test, the Green and O’Brien score and the PWRE.

Results: Clinical assessment was available for 59 patients who also responded to the questionnaires. Mean follow-up was eight months. Healing was achieved in six weeks. There were no cases of secondary displacement nor of lost reduction. The mean Green and O’Brien assessment was 85% good and very good outcome, the mean DASH score was 20.6 and the mean PWRE was 32.8.

Discussion: Appropriate fixation for fractures of the distal radius remains a controversial issue, as illustrated by the variety of treatments used, the different materials proposed for fixation, and the large number of publications. The primary stability achieved with the locking screw in the LCP plate enables early rehabilitation. The absence of secondary displacement, irrespective of the quality of the bone, enables equivalent results in osteoporotic patients as in younger patients. No other material has enabled equivalent results to date. This is a major advance in osteosynthesis.

Purpose of the study: Since 2001, we have used arthroscopy systematically to control the treatment of distal radius fractures. We report our three years experience.

Material and methods: Arthroscopic control was used for all patients aged less than 65 admitted to our unit for treatment of an articular fracture of the distal radius. The same operator performed all procedures. Fixation methods were: K-wire pinning, locked plating (Synthes) or a combination of these two methods. The arthro-scope had a 2.4 mm optic. Bony lesions were noted according to the Cataign, Fernandez and AO classifications. The DASH, Green and O’Brien, and PWRE scores were noted.

Results: Intraoperative arthroscopic control was performed for 61 patients between November 2001 and November 2004. Mean follow-up was 17 months (range 6–36 months). Arthroscopic exploration revealed: scapholunate ligament tears (n=11), lunotriquetral ligament injuries (n=3), pathological perforations of the triangle complex (n=4), damage to the radial cartilage (n=15), and mirror involvement of the carpal cartilage (n=4). An arthroscopic procedure was necessary to treat a bone or ligament lesion in 28 cases. At last follow-up, the DASH score was 19.3 and the PWRE 37.6.

Discussion: Arthroscopic evaluation of articular fractures of the distal radius, a routine practice in English-speaking countries, remains a limited practice in France. There is nevertheless a real advantage of using intraoperative arthroscopy. The particular anatomy of the radial surface makes it impossible to achieve proper assessment on the plain x-ray for a quality reduction of the fracture. Recent ligament injuries are rarely detectable on a wrist x-ray. An intra-articular stair-step or an untreated ligament injury can pave the way to short-term development of osteoarthritic degeneration. Intraoperative arthroscopic control is the only way to diagnosi and treat these osteoligamentary lesions observed in patients with an articular fracture of the distal radius. For us, non use of intraoperative arthroscopy constitutes a lost chance for patients with an articular fracture of the distal radius.
