[Aseptic nonunion of patella at the Centre Hospitalier Universitaire Bocar Sidy Sall de Kati about 25 cases].

OBJECTIVE

The objective of Our study was to describe the epidemiological, clinical, therapeutic and prognostic aspects of Nonunion of patella fractures.

PATIENTS

METHODS

It was a retrospective study done concerning 25 patients treated fromJanuary 2005 to December 2015 in the orthopedic trauma service CHU Bocar Sidy SALL Kati.

RESULTS

We gather together 25 cases of Nonunion of patella fractures disease among 28 caseswhich was about 89.28%. Our patients were divided into 20 men and 5 women, mean age was 36 years, ranging from ages 22 to 75 years. Posttraumatic period was 6-18 months. The initial fracture was neglected in 21 cases and treated in 4 cases. Physical examination revealed lameness in 92% of cases, atrophy of the quadriceps in 56% of cases, joint stiffness, 56% and an inter-fragmentary gap in 92% of patients. The radiographic data were consistent with pseudoarthrosis in all cases. The inter-fragmentary gap was 36 mm on average. The care of our patients was based on plugging and guy-wiring in 64 % of cases and strapping pre- and peri patella in 12% of cases. A partial patellectomy was practiced in 2 cases. A VY plasty of the quadriceps was recommended in 4 cases.The patients were reviewed after a mean of 10 months (8 months- 24 months). Functional outcomes analyzed using Bostman scores were excellent in 4 cases (16%), good in 18 cases (72%) and poor in 3 cases (12%).

CONCLUSION

Nonunion of the patella is mostly due to the lack of treatment or wrong treatment leads. Treatment with plugging and guy-wiring seems the most appropriate method.
