Apport de l’arthrodistension dans la prise en charge de la capsulite rétractile primitive de l’épaule : étude comparative versus rééducation

Objectives

To describe the epidemiological and clinical features of patients with primitive adhesive capsulitis of the shoulder treated by capsular distension and then rehabilitation; to evaluate the short-, mid- and long-term efficiency of this therapeutic protocol and compare it with rehabilitation alone.

Materials and methods

This was a two-year prospective study. Sixty patients were included and divided into populations P1 (capsular distension and rehabilitation) and P2 (rehabilitation only). Assessment of the treatments’ efficacy was based on the following parameters: pain on a visual analogue scale (VAS), joint motion in several axes, a simplified Constant score (functional ability) and the SF-36 quality of life score.

Results

Thirty patients (mean age: 56) underwent capsular distension. The Constant score was judged to be poor in over half of the patients. All the quality of life parameters were modified. When compared with P2, the P1 group showed a statistically significant improvement in terms of the pain score (p = 0.005), anterior elevation (p = 0.001), lateral elevation (p = 0.005), external rotation (p = 0.006) and the Constant score (p < 0.001) one week after capsular distension. One year after capsular distension, this gain persisted in a statistically significant manner for all functional parameters and all SF-36 dimensions (p < 0.001 for PF, RP, BP, SF and RE; p = 0.01 for GH and VT and p = 0.002 for MH).

Conclusion

Our results show that capsular distension and subsequent intensive rehabilitation have a beneficial effect. This combination enables rapid, significant improvement from the first week onwards. The improvement phase lasts for one month and may hold steady for up to 12 months.
