The aim of this study was to evaluate the results of minimally invasive percutaneous plate osteosynthesis (MIPPO) of distal femoral fractures in elderly diabetic patients with osteoporotic bone. Thirteen supracondylar or intercondylar femoral fractures were treated by MIPPO with a locked plate without bone grafting. All fractures healed, with only one delayed union in a patient who had deep infection. Results were evaluated using Schatzker and Lambert's criteria; all patients had excellent, moderate or good results except one with a poor result. Minimally invasive percutaneous locked plating provided favorable results in the treatment of distal femoral fractures in this geriatric population. 相似文献

Between October 1995 and December 1998, 16 patients with A-O type A3, C2 or C3 supracondylar femoral fractures were treated by open reduction and internal fixation using indirect reduction and bridge plating. Seven (44%) patients had open fractures. The patients were followed for a mean of 46 months (range 24-71). All fractures healed. The average time for fracture healing was 18.5 weeks (range 12-28). Four primary bone grafts and three secondary bone grafts were performed. By using the modified Schatzker rating scale, the result of 13 patients (81%) were rated as excellent or good. Complications included two implant failures that were due to full weight bearing before bone healing, and one superficial delayed wound healing. No deep infections were found in this series. The open fracture group needed longer time to heal and had a higher rate of receiving bone grafts. We conclude that indirect reduction and bridge plating with a 95 degrees dynamic condylar screw (DCS) or condylar blade plate can produce favourable results for complex distal femoral fractures. We suggest primary bone grafts or early secondary bone grafts for comminuted open fractures using an indirect reduction technique. 相似文献

A cadaveric arterial injection study was performed to study the effects of percutaneous and conventional surgical plating
techniques on femoral vascularity. Sixteen-hole dynamic condylar screw and condylar buttress plates were applied on the proximal
and distal shafts, respectively, of intact femora in ten human cadavers. On one side, the plate was inserted using a lateral
conventional plate osteosynthesis (CPO) technique with elevation of the vastus lateralis muscle to expose the shaft. On the
contralateral side, the plate was inserted percutaneously beneath the muscle using a minimally invasive plate osteosynthesis
(MIPPO) technique. After plating, blue silicone dye was injected through the common femoral artery. A dissection was then
performed to identify the femoral perforating arteries (PAs). The pattern of periosteal filling of the injected dye was analyzed.
The MIPPO technique maintained the integrity of the PAs and exhibited superior periosteal perfusion. The results of this study
indicate that the MIPPO technique maintains femoral vascularity and perfusion better than the CPO technique.

Double plating of unstable proximal tibial fractures using minimally invasive percutaneous osteosynthesis technique 总被引:1,自引:0,他引:1
BACKGROUND: Double plating of proximal tibial fractures with traditional open osteosynthesis gives a stable fixation, but may be complicated by wound healing problems. Minimally invasive methods have been recommended to decrease the wound complication rates. We report the efficacy of double plating of proximal tibial fractures using a minimally invasive percutaneous technique. PATIENTS AND METHODS: 23 proximal tibial fractures in 23 patients (mean age 54 (36-78) years) were treated with double plating using a minimally invasive percutaneous technique. Functional and radiographic results were evaluated by a modified Rasmussen scoring system. RESULTS: All fractures healed. The average time for fracture healing was 19 (10-32) weeks. 21 patients had excellent or good clinical and radiographic results. 2 patients had a fair clinical result because of associated knee injuries. Complications included 1 case of shortening (1 cm) and 2 cases of mild malalignments (varus less than 10 degrees ). There was 1 case of superficial infection that healed after removal of the plate. No deep infections occurred. INTERPRETATION: Double plating using minimally invasive percutaneous technique can provide favorable results in the treatment of proximal tibial fractures. 相似文献

Ipsilateral hip and distal femoral fractures 总被引:8,自引:0,他引:8
We tried to find the trauma mechanism and treatment rationale of ipsilateral concomitant hip and distal femoral fractures involving the articular surface. Between 1988 and 1995, 15 cases of ipsilateral hip (confined to neck or trochanteric areas of the femur) and distal (confined to supra- and intercondylar area of the femur) femoral articular fractures were collected. The hip fractures consisted of 10 trochanteric fractures and five neck fractures, which were managed with reduction and fixation in 14 (Knowles' pin in eight, DHS in four and standard Gamma nail in two), and primary bipolar hemiarthroplastry in one. The distal femoral articular fractures were open in 11; these were managed with radical debridement, implantation of Septopal chains and immediate internal fixation, followed by prophylactic autogenous bone grafting 6 weeks later in the recent six cases (five Judet plates, four dynamic condylar screws and two condylar plates). The other four closed distal femoral fractures were managed with early reduction and internal fixation (two Judet plate, one dynamic condylar screw and one condylar plate). The union time was 20.3 (12-48) weeks for proximal fractures and 23.7 (12-36) weeks for distal fractures. Early infection developed in three cases. Nonunion of a femoral neck fracture developed in one case. The other complications were implant failure in one, coxa vara in one, refracture in one, delayed union in one and knee stiffness in one. 相似文献

BACKGROUND: Despite various treatment methods, proximal tibial fractures are common injuries associated with poor outcomes and high rates of complications. To improve this, a percutaneous plating technique was performed to treat proximal tibial fractures. METHODS: Twenty-four proximal tibial fractures (17 proximal fractures [AO 41] and 7 proximal shaft fractures [AO 42]) were treated using percutaneous plating with either or both sides without bone graft. One was an open fracture. RESULTS: All fractures healed. The average time for fracture healing was 16.5 weeks (range, 8-24 weeks). Complications included one case of shortening (1 cm) and two cases of malalignments; one valgus of 6 degrees and one varus of 5 degrees. There was one case of superficial infection that was healed after removal, but no patient showed deep infection. Results were evaluated by the modified Rasmussen scoring system. Most patients had excellent or good results; only one patient had fair results. CONCLUSION: Minimally invasive percutaneous plating can provide favorable results in the treatment of proximal tibial fractures. 相似文献

In a prospective study, 14 cases of supracondylar or subtrochanteric fractures or osteotomies were stabilized with a dynamic condylar screw (DCS) inserted using a minimally invasive percutaneous plate osteosynthesis (MIPPO) technique. The technique consisted of 4 major steps: 1) placement of the guide wire under fluoroscopic control and condylar screw insertion through a stab incision; 2) plate insertion beneath the vastus lateral muscle; 3) engagement of the condylar screw to the plate using a modified T-handle and, 4) plate fixation to the shaft using percutaneously inserted self-cutting screws. Between October 1994 and December 1995, 14 cases in 12 patients met the inclusion criteria. There were 11 acute fractures (6 subtrochanteric, 5 supracondylar) and 3 corrective osteotomies. Nine fractures were closed, and 2 were open. One 97-year-old patient died 6 weeks after trauma. There were no infections and 12 of 13 cases healed without a second procedure. There was 1 implant failure (plate screw breakage), which required repeat fracture fixation. At follow-up, there were 2 varus deformities above 5 degrees, 2 shortenings over 20 mm, and 1 rotational deformity of 20 degrees. According to the Neer score, there were 6 excellent, 1 satisfactory, 3 unsatisfactory results and no failures. The results of this technique compare favourably with those of other series of osteosynthesis of subtrochanteric or supracondylar femoral fractures treated with internal fixation without the added morbidity associated with an extensive approach or autogenous bone grafting. However, the surgical technique is demanding, and care must be taken to restore the axial alignment. 相似文献

Minimally invasive plate osteosynthesis: does percutaneous plating disrupt femoral blood supply less than the traditional technique? 总被引:27,自引:0,他引:27

OBJECTIVES/HYPOTHESIS: Proximal and distal femur fractures have traditionally been treated with open reduction and internal fixation through a standard lateral approach. New, "minimally invasive" internal fixation techniques, however, have been developed in an effort to devascularize the bone less than the traditional method. The purpose of this study was to determine whether a minimally invasive percutaneous plating technique better preserves bone vascularity relative to the traditional method by comparing the effect of the two approaches on the blood supply of the distal femur using silicone arterial dye injection in a cadaveric model. STUDY DESIGN/METHODS: Ten fresh human cadavers underwent lateral conventional plate osteosynthesis (CPO) through a standard lateral approach on one side and minimally invasive plate osteosynthesis (MIPO) through two three-centimeter incisions on the contralateral side. After injection of silicone dye, a dissection was performed bilaterally to identify the femoral perforating and nutrient arteries. RESULTS: All MIPO specimens showed intact perforating and nutrient arteries, whereas the CPO specimens had a variable incidence of vessel disruption. The MIPO group demonstrated better periosteal perfusion in each of the cadavers and improved medullary perfusion in 70 percent of the MIPO specimens compared with the CPO specimens. CONCLUSION: A percutaneous minimally invasive plating technique disrupts the femoral blood supply less than the traditional open method. Such minimally invasive methods may be more advantageous biologically than the traditional method. 相似文献

Bridge-plating with its advantages in terms of vascularity and bone healing is a well established procedure today in the treatment of comminuted femoral fractures. Bridge-plating means that the fracture site is not interfered with during the operative procedure. This paper introduces a surgical technique in which the plate is inserted through isolated proximal and distal incisions only, behind the vastus lateralis. Alignment is secured by the plates, the fracture site remains untouched, fixation and screw insertion is restricted to the proximal and distal main fragments. Longitudinal femoral fractures extending right into the trochanteric and or condylar areas are the main indication for minimally invasive plate fixations with angled blade plates or condylar screws since fractures which are restricted to the diaphyseal area are mostly treated by nailing today. The surgical trauma resulting from plating by proximal and distal incisions only is less than that associated with conventional techniques. Indirect reduction of femoral fragments is much easier since the integrity of the surrounding muscles and soft tissue is preserved, the fragments often being reduced simply by traction. Adjustment of rotation is an essential aspect requiring careful attention. For special indications, namely comminuted fractures affecting a large part of the femur and extending into the trochanteric or condylar areas, insertion of the plate via proximal and distal incisions only is a further development in bridge-plating which minimizes surgical trauma and operation time. 相似文献

Osteosynthesis in fracture treatment and in some reconstructive procedures with blade plates or dynamic screw systems was the standard procedure for several decades. In this review, the current options and concepts using blade plate osteosynthesis, stabilization of proximal and distal femur fractures and reconstructive procedures with the dynamic hip screw or the dynamic condylar blade are discussed. On the basis of a literature review, the present indications, results and region-specific complications are reported and discussed. Blade plates are used mainly in the context of reconstructive procedures, as well as in the treatment of pseudoarthroses. The Pauwel procedure in femoral neck non-unions is one of the best known indications. In contrast, the dynamic hip screw is the gold standard for stabilization of femoral neck and most pertrochanteric fractures, whereas the dynamic condylar screw is still an alternative to internal fixators for proximal and distal femoral fracture fixations. 相似文献

IntroductionThis study aims to identify patient and intra-operative factors that contribute to non-union in locked lateral plating for distal femoral fractures.MethodsSystematic searches of English-language articles in Ovid Medline, PubMed, Embase, Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews were undertaken in February 2018 according to the PRISMA guidelines. The search terms were (fracture or fracture*) AND (distal femur or distal femoral) AND (malunion or non-union). Eligible studies published at any time reported non-union rates and compared patient and intraoperative factors in patients who underwent locked lateral plating for traumatic distal femoral fractures. The quality of included papers was assessed using The Journal of Bone and Joint Surgery levels of evidence (Wright et al., 2003), and further appraised using the Downs and Black score (Downs and Black, 1998).ResultsEight studies investigating 1380 distal femoral fractures were found to satisfy the inclusion and exclusion criteria. These studies analysed a variety of patient and intra-operative factors that may contribute to non-union. These include high BMI, open fracture, comminution, fracture infection, stainless steel plate material, shorter working length, open reduction and internal fixation when compared with minimally invasive plate osteosynthesis, high construct rigidity scores and purely locking screw constructs.ConclusionThis review has identified multiple factors which potentially contribute to non-union including stainless steel plate material, high construct rigidity scores and purely locking screw constructs. These findings may reflect that overly rigid plating constructs can contribute to non-union. However, they should be taken in the context of heterogeneity amongst included studies, with further research necessary to support these findings. 相似文献

Supracondylar femoral fractures still present a challenge to the treating surgeon. The incidence of delayed and non-unions is reduced due to the minimally invasive plating techniques, but establishing a correct axis and good function is still a problem. During the last few years new implants have been developed to allow less difficult operative techniques in minimally invasive surgery. The Less Invasive Stabilization System (LISS) is a percutaneous plating system with monocortical self-drilling screws. The screws are inserted with an aiming guide and form a stable angle with the plate. The distal femoral nail allows placement of a spiral blade in the nail, thereby enhancing the interlocking stability. 相似文献

Helical plating of the proximal humerus 总被引:4,自引:0,他引:4
The ideal treatment for fractures of the proximal humerus has not been definitively agreed upon. Several recent reports have described a technique of helical plating for proximal humeral fractures, in which the proximal plate is placed laterally on the greater tuberosity, and spirals 90 degrees distally to lie on the anterior surface of the humeral shaft. The purpose of this study was to evaluate the feasibility of helical plating using a less invasive surgical approach and placing screws percutaneously in the distal plate. Dissection of 10 cadaveric upper extremity specimens was performed, using an extended anterolateral acromial approach followed by percutaneous helical plating. With the plate secured, the neurovascular structures which crossed the anterior humerus superficial to the plate were exposed and identified. Only the musculocutaneous nerve crossed anterior to the plate and was at risk for percutaneous screw placement. The nerve location was found in a consistent location among the specimens. The danger zone for the nerve location was found to be at an average of 13.5 cm from the greater tuberosity (99% CI: 12.2-14.8 cm). Though clinical experience is necessary to validate this plating technique, it appears that avoiding this danger zone in which the musculocutaneous nerve crosses will allow safe percutaneous screw placement and permit minimally invasive plating of these fractures. 相似文献
