Abstract
Objective: 6 cases of postraumatic arthritis of the distal radius treated by chondro costal graft are reported with a minimum follow up of 2 years
Material and methods: 6 patients (One 22 years old patient with a dislocated radiocarpal joint 6 months after an injury, 3 patients (48, 52 and 53 years old) respectively 1, 1,5 and 2 years after a intraarticular fracture of distal radius and a patient (74 years old) with radio lunate arthritis reported two mains complaints : pain and stiffness. The last patient was a female with a destruction of radio scaphoid joint after septic complication of scaphoid surgery. Location of the cartilage defect was central in two cases and palmar in the others. A dorsal approach in one case, a palmar approach in the five others allowed reduction and reconstruction of the destroyed radial part of joint. An osteochondro costal graft harvested on the eight’s rib was inserted and fixed by plate in place of the articular impaction. Plaster cast of 3 months in the first case and 1 month in the others cases followed the articular reconstruction
Results : No complication have been pointed. Union was achieved in all 6 cases. Integration and viability of the graft were evaluated with RMI. At the highest follow up functionnal result are excellent in the youngest first case (male, 22 years old) where motion and grasp are similar than the controlateral side. In the 4 others cases of mal union patients were pain free in daily activity with a functionnal wrist score of 72/100 (54–82) and a DASH of 38,3 (22,5–51,7). Only the case with the septic problem failed with pain at follow up.
Conclusion: Reconstruction of a partially destroyed articular surface by a costal graft is reliable and allows filling and resurfacing an articular cartilage void. If chondro costal graft is currently used in maxillo facial surgery it is the first report in post traumatic arthritis secondary to intra articular mal union.
