The primary arthrodesis for severely comminuted intra-articular fractures of the calcaneus: A systematic review

Background: Although open reduction and internal fixation via the extended lateral approach is currently considered gold-standard, severely comminuted calcaneal fractures might not be amendable for reconstruction. The primary aim of the current review study was to assess the functional outcome of the primary arthrodesis in the management of comminuted displaced intra-articular calcaneal fractures. Methods: The literature was searched for studies published between January 1st 1990 and December 1st 2010, to identify studies in which a primary arthrodesis was utilized for the treatment of displaced intra-articular calcaneal fractures between. The methodological quality of the included studies was assessed using the Coleman Methodology Score. Results: Seven case series and one abstract were identified, reporting on 120 patients with 128 severely comminuted calcaneal fractures. Average follow-up time was 28 months and union rate 97%. Functional outcome was assessed using the modified AOFAS score in seven studies; with a weighted average of 77.4 (range 72.4-88). One study reported a 75% good to excellent outcome on the Paley score. Three studies reported on return to work, ranging from 75 to 100%. Overall reported wound complications occurred in 19.4%. The average Coleman Methodology Score was 56 (range 38-68) points. Conclusions: The primary arthrodesis for the treatment of Sanders type-IV comminuted displaced intra-articular calcaneal fractures provides overall good results considering the severe nature of the injury. Therefore, in the process of choosing the best treatment modality for a severely comminuted calcaneal fracture, the primary arthrodesis should receive full consideration.
