Outcome of acetabulum fractures treated with open reduction and internal fixation through Kocher-Langenbeck Approach:...

Complex anatomy of acetabular fracture is quite challenging for the orthopedic surgeons. Many Acetabular fracture fixation approaches have been used for a long time to treat different fracture patterns of acetabulum. Kocher-Langenbeck Approach (K-L approach) of acetabulum fracture is usually used by most of orthopedic surgeons. In this retrospective study, we evaluated the clinical and functional outcome of subtypes of acetabulum fractures treated with K-L approach. Assessment of Intra and postoperative complications of subtypes of acetabulum fractures was also done.

Eighty patients (48 men and 32 women) were included in this retrospective study with a mean follow-up period of 2.6 years. Fractures were classified according to Letournal and Judet classification. K-L approach was performed in all these patients. Post operative reduction, Radiological outcome was quantified using Matta's criteria while the functional outcome was assessed according to Merle d'Aubigné and Postel scoring system. Postoperative complications were evaluated.

The mean age of a total of 80 cases was 43.64 ± 13.24 year. The type of fracture was found to be significantly associated with concentric/non-concentric reduction (p = 0.003) and with post op reduction (p = 0.005). The post operative reduction was found to be significantly associated with radiological (p < 0.001) and functional outcome (p < 0.001) at one year post op. The type of fracture was found to be significantly associated with radiological outcome (p < 0.001) while non-significantly found to be associated with functional outcome at 1 year (p = 0.050). The type of fracture was found to be significantly associated with post op complications (p = 0.003) and with arthritis (p = 0.001).

K-L approach is a multifaceted and convenient approach for treating acetabulum fractures. Type of fracture and post-operative reduction are key factors for a satisfactory outcome. Transverse with posterior wall fracture has the worst prognosis.
