Role of Bone Grafts and Bone Graft Substitutes in Isolated Subtalar Joint Arthrodesis

چکیده
OBJECTIVES The purpose of this study was to compare union rates for isolated subtalar arthrodesis with and without the use of bone grafts or bone graft substitutes. METHODS We retrospectively reviewed 135 subtalar fusions with a mean follow-up of 18 ± 14 months. The standard approach was used for all surgeries. Graft materials included b-tricalcium phosphate, demineralized bone matrix, iliac crest autograft and allograft, and allograft cancellous chips. Successful subtalar fusion was determined clinically and radiographically. RESULTS There was an 88% (37/42) union rate without graft use and an 83% (78/93) union rate with bone graft use. Odds ratio of union for graft versus no graft was 0.703 (95% CI, 0.237-2.08). The average time to union in the graft group was 3 ± 0.73 months and 3 ± 0.86 in the non-graft group, with no statistically significant difference detected (p = 0.56). CONCLUSION Graft use did not improve union rates for subtalar arthrodesis. Level of Evidence IV, Case Series.

Subtalar arthrodesis by cancellous grafts and metallic internal fixation.
A technique of subtalar arthrodesis by means of metallic internal stabilisation and autogenous cancellous bone grafting is described. Of forty-eight feet with mobile pes planus treated by this method forty-five gained union after an average of seven and a half weeks in a below-knee weight-bearing plaster, and forty-three had satisfactory correction of the deformity.
متن کاملGuided tissue regeneration with heterologous materials in primary subtalar arthrodesis: a case report.
BACKGROUND Calcaneal fractures are relatively rare and difficult to treat. Treatment options vary based on the type of fracture and the surgeon's experiences. In recent years, surgical procedures have increasingly been used due to the better long-term results. We present a case where guided tissue regeneration was performed in a calcaneal fracture that needed primary subtalar arthrodesis. We us...
متن کاملBone grafts and their substitutes.
The continual cycle of bone formation and resorption is carried out by osteoblasts, osteocytes, and osteoclasts under the direction of the bone-signaling pathway. In certain situations the host cycle of bone repair is insufficient and requires the assistance of bone grafts and their substitutes. The fundamental properties of a bone graft are osteoconduction, osteoinduction, osteogenesis, and st...
متن کاملMinimally invasive, no hardware subtalar arthrodesis with autogenous posterior iliac bone graft
Sixteen patients underwent minimally invasive subtalar arthrodesis through a mini-invasive approach with posterior iliac graft between 2004 and 2006. No hardware was used to transfix the arthrodesis and partial weight bearing was allowed immediately. The primary indication for surgery was the squeal of fracture os calcis in terms of subtalar joint arthritis, loss of heel height, malalignment of...
متن کاملA simple method of fusion of the subtalar joint in children.
The number ofchildren in whom subtalar stabilisation is indicated is diminishing, largely because ofthe disappearance ofanterior poliomyelitis, which so often accounted for an unstable valgus foot, with or without fixed equinus, and less often a calcaneo-varus or cavo-varus foot. Cerebral palsy is quite often associated with valgus accompanied by supination ofthe forefoot. The latter can become...
