Abstract:
Objective To compare treatments of intra-articular calcaneal fractures with and without bone graft in foot and ankle surgery.Methods A comprehensive search was conducted on line for all English research articles published from January 1990 through December 2010 dealing with open reduction and internal fixation with and without bone graft for intra-articular calcaneal fractures.Two reviewers evaluated each study to determine whether it was eligible for inclusion and collected the data of interest.Meta-analytic pooling of group results across studies was performed for the 2 treatments.Results The systematic review identified 32 qualified primary studies with 1281 fractures.No significant differences were found in postoperative infection, osteoarthritis or subtalar fusion between the 2 treatments ( P ＞ 0.05) .The average full weight-bearing time in bone graft treatment was significantly lower (5.4 weeks) than in non-graft treatment (10.5 weeks) .The mean B(o)hler angle was significantly larger and long-term loss of collapse significantly lower in bone graft treatment than in non-graft treatment.The bone graft treatment had a lower American Orthopaedic Foot and Ankle Society (AOFAS) score (71.4 points vs.80.5 points) but a higher Creighton score (89.9 points vs.81.0 points) compared with non-graft treatment.Pooled mean results showed no significant differences in the weighted excellent-to-good rate between the 2 treatments (excellent 35%, good 40%, fair 21% and poor 4% for the bone graft treatment versus excellent 34%, good 42%, fair 14%, and poor 10% for the non-graft treatment).Conclusions Open reduction and internal fixation with bone graft for intra-articular calcaneal fractures may lead to better reduction of B(o)hler angle and early return to full weight-bearing without increased risk of postoperative infection.However, since more cases of joint depression and comminuted fracture have been included in the bone graft group in the present study, a prospective controlled comparative study with a large scale of samples is still needed.
