Early postoperative improvements in the QuickDASH score after distal radius fracture are related to the type of surgical treatment.

The goal of this prospective study was to evaluate the real-life experience of 52 patients and their recovery kinetics in the first 6 weeks after surgical treatment of distal radius fractures. The fractures were treated with either a fourth-generation volar locking plate (34 patients, mean age 67 years, range 54-82) or by percutaneous pinning (18 patients, mean age 56 years, range 43-69). These patients were evaluated every week for 6 weeks with the QuickDASH (QD) questionnaire. A lower QD score indicated that the patient's physical function and symptoms had improved. At postoperative week 1, all the patients who had undergone percutaneous pinning had a QD of 80 (out of 100). One-third of patients who had undergone plate fixation had a QD of 80, while the remainder had a QD of 65. Out of all the patients who had a QD of 80 at postoperative week 1, the patients who had undergone plate fixation improved more quickly. After 6 weeks, the patients who had undergone plate fixation had a greater reduction in the QD (50 points) than the ones who had undergone pinning (30 points). Although the direct costs of locking plate fixation are 10 times higher than those of K-wire pinning, evidence suggests that these plates reduce the indirect costs. This study has shown that a patient's recovery rate, day-to-day life and physical function are better over the first 6 weeks postsurgery when the distal radius fracture is fixed with a locking plate.

Cementless total knee arthroplasty in chronic inflammatory rheumatism.

INTRODUCTION: We report a short-term monocentric retrospective evaluation of cementless total knee arthroplasty (TKA) in a population suffering from chronic inflammatory rheumatism. MATERIALS AND METHODS: We have reviewed 23 patients (34 knees) with an average age of 55 years (range 26-78), bearing a TKA for chronic inflammatory rheumatisms with a 6-year follow-up (range 3-12); 78% suffered from rheumatoid arthritis and 15% from juvenile rheumatoid arthritis. We used a cementless total prosthesis sacrificing the posterior cruciate ligament and bearing an ultra-congruent rotational tibial insert, the Natural Knee (NK2™) (Zimmer(®), Warsaw, IN, USA). At last follow-up, an independent surgeon performed a clinical assessment for pain, function and quality of life using International Knee Documentation Committee score, International Knee Society (IKS) score and Devane's score. A radiographic study evaluated secondary fixation according to the radiographic index of the Knee Society and according to Ewald's score. RESULTS: The mean postoperative IKS score was 83 points (range 40-100) for the knee score and 74 points (range 20-100) for the function score. Radiographic assessment came across only one case of loosening, concerning the tibial component on an asymptomatic patient. We came across the following complications: 1 early infection, 2 important postoperative flessum deformity having needed an arthrolysis, 1 supracondylar fracture of the femur and 1 fracture of the patellar component. Survival rate at 6-year follow-up is 97% taking into account one case of revision. CONCLUSION: Non-cementation of this implant in chronic inflammatory rheumatism does not result in a higher rate of loosening. In this series, patients own satisfaction, function of the knee and survival rate are rather good. LEVEL OF EVIDENCE: Retrospective, no control group, Level IV.
