POSTOPERATIVE ARTICULAR CHONDROLYSIS OF THE UPPER LIMB AFTER JOINT IRRIGATION WITH CHLORHEXIDINE: NINE CASES



Abstract

Purpose: Operative wounds are commonly washed with a more or less diluted antiseptic solution to prevent infection or to treated overt infection. Chlorhexidine is widely used. We report the cases of nine patients who developed joint destruction attributed to peroperative irrigation with a chlorhexidine solution.

Material and methods: Nine patients (three men and six women) who had undergone surgery in another facility were referred to our unit for unexplained postoperative chondrolysis. The joint localisations were: wrists (n=7) after surgery for a dorsal arthrosynovial cyst (mean age 37 years); elbow (n=1) after surgery for epicondylalgia (age 49 years); shoulder (n=1) after arthroscopy for sub-acromial impingement (age 51 years).

The time between surgery and the first consultation in our unit varied from three to nine years (mean five years four months). Persistent stiffness had been noted in the postoperative period with pain at joint mobilisation which worsened progressively. For the patients with chondrolysis of the wrist: the x-rays demonstrated destruction of the radius-first ray joint in one, the medio-carpal joint in four and overall destruction in two. Overall joint destruction was also observed in the elbow and shoulder patients. Search for other causes of joint destruction was negative; infection and inflammatory rheumatoid disease were ruled out. The common feature identified in all patients was joint irrigation with a chlorhexidine solution (Biseptine®).

Results: Four of the nine patients underwent surgical treatment: a four-bone arthrodesis with scaphoidectomy was used for the three patients with mediocarpal involvement and a shoulder arthrodesis was performed in one patient. The pathology study demonstrated cartilage defects filled with dense strongly hyalinised acellular tissue. Bacteriological specimens were all negative.

Discussion: The chondrolytic effect of chlorhexidine, a member of the biguanide family, was first reported in 1986 with a few cases described with knee involvement. Experimentally, there would be a dose-dependent effect. The mechanism involves a disorganisation of the cell membrane with cartilaginous necrosis and ostocartilaginous resorption. Individual predisposition cannot be ruled out.

Conclusion: In light of these observations, it would be advisable to avoid peroperative joint irrigation with chlorhexidine solution.
