The metaphyseal defects in 40 patients with displaced tibial plateau fractures necessitating surgical repair were filled with either cancellous autograft or interporous hydroxyapatite. Roentgenographic and clinical assessments at follow-up periods averaging 15.4 months (autograft) and 34.5 months (hydroxyapatite) demonstrated no significant differences in the two groups. Interporous hydroxyapatite is a safe, effective alternative to autogenous cancellous bone for the filling of metaphyseal defects associated with tibial plateau fractures. 相似文献

An injectable calcium phosphate cement as a bone-graft substitute in the treatment of displaced lateral tibial plateau fractures 总被引:15,自引:0,他引:15
In the treatment of displaced tibial plateau fractures, filling the resultant metaphyseal defect is essential for maintaining reduction. This study reports on 14 patients with an average age of 53 (range 34-63) years who sustained such a fracture and whose tibial defect was augmented with an injectable calcium phosphate cement under arthroscopic and fluoroscopic control. Eight fractures were treated with subcortical percutaneous screw fixation, plates were used in four cases and two fractures were treated with bone cement only. Full weight-bearing was allowed after 6-12 weeks. At the last follow-up which averaged 28 (range 18-47) months, the reduction achieved at the index operation was not altered in any of the patients except one. Most patients recorded little or no pain with an average VAS score of 1.2 (0-3.4). Ten patients had no limitation of their walking distance. Patient satisfaction was good or excellent in 12 cases. Flexion averaged 140 degrees (range 130-150 degrees ) and extension was unlimited in 13 patients. The Lysholm knee score averaged 80 and the Knee Society score 180 (range 127-195). In our opinion the injectable calcium phosphate cement used here is a promising alternative for filling metaphyseal defects in the treatment of displaced tibial plateau fractures. 相似文献

Reduction of the depressed joint surface in tibial plateau fractures often leaves large cancellous bone defects. These metaphyseal voids are typically filled with autogenous bone grafts that can cause a significant donor site morbidity. The use of injectable bone cement offers the opportunity to support the reduced joint surface without bone grafting. The aim of this study was to evaluate the clinical and radiological outcome as well as the period of partial weight bearing after the use of Norian SRS in tibial plateau fractures. Twenty-one patients with a mean age of 48 years were included in this prospective trial. According to the AO/OTA Classification, there were seven fractures of type B2, ten B3, one C1, one C2, and two fractures of type C3. The period of partial weight bearing was 3.7 weeks. In 18 patients the follow-up was more than 24 months. After a mean follow-up of 30 months, the Lysholm score was 87.9 at mean. The radiological part of the Rasmussen score was excellent and good in eight cases each and fair in four cases. Soft tissue reactions due to the cement were not observed. On all radiographs taken 36 months after the operation the cement bloc was still visible. The results show that Norian SRS can be used to fill metaphyseal bone defects in tibial plateau fractures. Clinical and radiological results are comparable to those of fractures treated with autologous bone graft. The high compression strength allows early full weight bearing without the risk of secondary loss of reduction. 相似文献

Anatomic reduction of articular depression tibial plateau fractures is challenging. The authors describe a new technique using percutaneous balloon-guided inflation osteoplasty for a depressed lateral tibial plateau fracture. The fluoroscopy-guided inflation osteoplasty restores the joint surface anatomically in a minimally invasive fashion. The metaphyseal void is filled with a fast-setting fluid-phase bone substitute, and a lateral buttress plate is applied with less invasive incisions. This technique is a valid alternative for indirect reduction of depressed articular tibial plateau fractures. 相似文献

ObjectivesIn recent years, the increase in utilisation of bone substitutes in the reconstruction of bone defects has been fuelled by donor site complications associated with autologous bone harvesting. However the ability of bone substitute to stimulate bone union while maintaining fracture reduction has been a topic of debate. Cerament Bone Void Filler (CBVF) is a novel biphasic and injectable ceramic bone substitute that has high compressive strength and the ability to promote cancellous bone healing.Materials and MethodThis is a retrospective study to evaluate the surgical outcome of utilising CBVF in the treatment of depressed metaphyseal bone fractures over a two year period. The patients were followed up for at least six months after surgery and clinical parameters such as wound site complications were collated. Radiographic imaging was evaluated to determine loss of fracture reduction and rate of cement resorption.ResultsThirteen patients with depressed metaphyseal fractures were enrolled, which included: (i) one proximal humerus fracture; (ii) three tibial plateau fractures; and (iii) nine calcaneal fractures. None of the patients showed significant collapse in fracture reduction after six months of follow up. Cement resorption was noted in one patient as early as three weeks after surgery. There were no cases of cement leak or wound site complications.ConclusionCerament Bone Void Filler (CBVF) is a promising bone graft substitute in the management of depressed metaphyseal bone fractures, with the ability to maintain fracture reduction despite cement resorption. 相似文献

Outcome of raft plate fixation of split depressed tibial plateau fracture without using a bone graft
S. Langhi R. Gul D. Owens P. Keeling P. Murray 《European journal of orthopaedic surgery & traumatology : orthopedie traumatologie》2007,17(1):77-79
Schatzcker type 3 tibial plateau fractures are common intra-articular injuries. These fractures can be associated with significant depression of articular surface, usually requiring open reduction, elevation of articular surface and rigid internal fixation. The resultant metaphyseal defect is filled with either cancellous autografts (Lachiewicz in Clin Orthop Relat Res 259:210–215, 1990) allografts or calcium phosphates to maintain the reduction. Percutaneous fixation (Koval in J Orthop Trauma 6:340–346, 1992) and ring fixators have been used to stabilize these fractures. Autogenous bone-graft harvesting is associated with significant morbidity with reported major complication rate of 8.6% and minor complication rate of 20.6% and there is a limited availability for larger defects. Allografts and bone substitutes are associated with their own problems (Segur in Arch Orthop Trauma Surg 117(6,7):357–359, 1998). The purpose of this study was to review the outcome of split depressed tibial plateau fractures treated by open reduction and internal fixation using subchondral raft plate fixation without the use of bone graft. 相似文献

Tibial plateau fractures with significant joint depression and metaphyseal comminution pose a challenge. In order to prevent the collapse of the articular surface, some authors propose filling the subchondral void created during reduction with bone graft/substitute, which can add further complications. We present two cases of tibial plateau fractures with severe joint depression of the lateral condyle; both treated with a periarticular rafting construct, in one caseadditional bone substitute was used and in the other case no bone graft/substitute was used; their final outcomes were reported. The treatment of joint depression in tibial plateau fractures using periarticular rafting constructs without bone graft, may be also a valid option, to achieve good final results without the morbidity associated with the use of bone graft/substitutes. 相似文献

Interference Screw Technique for Arthroscopic Reduction and Internal Fixation of Compression Fractures of the Tibial Plateau 总被引:1,自引:0,他引:1
James H. Lubowitz M.D. Kennan J. Vance D.O. Mina Ayala S.T. Dan Guttmann M.D. John B. Reid III M.D. 《Arthroscopy》2006,22(12):1063-1359.e3
Arthroscopic reduction and internal fixation (ARIF) is recommended as state-of-the-art treatment for patients with pure compression fracture of the tibial plateau. We describe a new technique for ARIF of pure compression tibial plateau fractures that uses a cannulated, bioabsorbable interference screw. After a guide pin is placed in the center of the compressed fragment and a tamp is used to elevate the fracture (with bone grafting as desired), the interference screw is advanced over the guide pin, resulting in both elevation and buttressing of the fracture. As compared with previously described techniques in which percutaneous buttress screws were used, ARIF attained with an interference screw via the tibial metaphyseal window allows substantially improved efficiency of surgical steps, improved preservation of the soft tissue envelope, definitive articular reduction under arthroscopic visualization, use of a bioabsorbable implant, and elimination of the need for fluoroscopy. 相似文献
