The authors describe a case of post-traumatic wrist arthritis with an osteochondral defect in the scaphoid fossa of the radius. The patient was treated with proximal row carpectomy, radial styloidectomy and reconstruction of the defect using the proximal half of the scaphoid as an autologous osteochondral graft. Pain relief was achieved while wrist motion and strength were improved. The carpal bones are a source of osteochondral grafts and can be used to expand the indications of motion-preserving wrist salvage procedures. 相似文献

In mutilans rheumatoid arthritis (RA) patients with major wrist destruction, wrist arthrodesis is recommended. This type of arthrodesis needs carpal reconstruction and stable fixation. The goal of this study was to assess the functional and anatomical outcomes of an iliac crest graft and internal fixation with two medullary pins. Six wrists in three patients suffering from RA were reviewed clinically and radiologically at an average follow-up of 25 months. We assessed the fusion of the iliac graft with the radius and the metacarpus, the preoperative and postoperative carpal height, and the bone stock in front of the thumb. All the patients had improved functionally. The iliac graft fused with the radius in all cases and fused with the metacarpus in 5 out of 6 cases; the non-union occurred in the wrist where only one pin was used. Restoration of carpal height was associated with improvements in hand function. The bone stock was sufficient to allow implantation of a trapezial cup during a total arthroplasty of the thumb trapeziometacarpal (TMC) joint. No major complications occurred. An iliac graft and two pins through the 2nd and 3rd metacarpals were used to reconstruct the carpal height and to obtain wrist fusion. Internal fixation with only one pin is not recommended. Functional improvement can be attributed to the normal tension within the extrinsic flexors and extensors of fingers and thumb being restored because the carpal height was restored. A secondary TMC arthroplasty is theoretically possible. 相似文献

INTRODUCTION: Apposition grafting is a method of choice for reconstruction of the anterior maxillary. The purpose of this work was to evaluate the success rate, the degree of bone resorption and the osteointegration of these grafts. MATERIAL AND METHODS: We reviewed retrospectively 36 cases of pre-maxillary bone apposition in patients operated from 1998 to 2002. Autografts were used for all patients. The harvesting site was parietal for 24 patients, intraoral for 8 and iliac for 4. RESULTS: There was two graft failures. The success rate was 94.5%. Partial resorption with effect on implantation was noted in 3 patients. Eighty implants were inserted successfully in 234 grafted sites with on average 2.4 implants per graft. Three implants were removed. Implant survival was 96.2%. DISCUSSION: This study demonstrated that the premaxillary apposition technique using autologous grafts provides sufficient bone volume to enable optimal implant insertion and stability. 相似文献
