Minimally invasive locking plate osteosynthesis for fractures of the distal tibia--results in 20 patients

AIMS: We report our experiences with minimally invasive locking plate osteosynthesis (MILPO), for distal tibia fractures, with specific reference to fracture union and complications encountered. PATIENTS AND METHODS: Twenty patients underwent MILPO for open and closed distal tibia fractures between March 2003 and December 2004. Fractures were classified according to the AO system. Open fractures were graded using the Gustilo and Anderson classification and closed fractures via the Tscherne classification system. RESULTS: There were 16 males and 4 females of mean age 44.7 years (range 19-69 years). Thirteen patients had temporary external fixation, prior to definitive fracture fixation. Minimum follow-up was 12 months and average time to full weight bearing in the closed fracture group (12 patients) was 18.1 weeks (range 8-32 weeks) and 19.3 weeks in the open fracture group (8 patients, range 8-44 weeks). Fracture healing was defined as radiological evidence of bridging mature callus combined with pain-free full weight bearing. In the open fracture group, four fractures united within 6 months, one within 6-12 months and one united 12 months after surgery; there were two cases of non-union. In the closed fracture group, seven fractures united within 6 months, three fractures between 6 and 12 months and two after 12 months from surgery. Two of the 20 patients required additional procedures to aid bone healing in the post-operative period. Three of the 20 patients required metalwork removal, for delayed wound breakdown in two cases and wound infection in one case. An uneventful recovery was made following this, in all three cases. There was one case of implant failure due to plate breakage at 32 weeks post-op. The fracture site was opened and re-plated at 32 weeks with a DCP. There were no complications following this. CONCLUSION: MILPO was used for definitive fixation of high energy, open and closed, peri-articular distal tibia fractures. This approach aims to preserve bone biology and minimise surgical soft tissue trauma. This surgical approach may provide an answer to treating a challenging group of fractures and further research is warranted.     

Minimally invasive plate osteosynthesis for humerus diaphyseal fractures

Background:

Minimally invasive plate osteosynthesis (MIPO) technique is reported as a satisfactory procedure for the treatment of humeral shaft fractures by the anterior approach by several authors. However, none of the published reports had a significant follow-up nor have they reported patient outcomes. We evaluated the clinical, radiographic, and functional outcome over a minimum follow-up of 2 years using the same MIPO technique to humeral shaft fracture.

Materials and Methods:

32 adult patients with diaphyseal fractures of the humerus treated with MIPO between June 2007 and October 2008 were included in the study. Patients with metabolic bone disease, polytrauma, and Gustilo and Anderson type 3 open fractures with injury severity score >16 were excluded from the study. All cases were treated with closed indirect reduction and locking plate fixation using the MIPO technique. The surgery time, radiation exposure, and time for union was noted. The shoulder and elbow function was assessed using the UCLA shoulder and Mayo elbow performance scores, respectively.

Results:

Of the 32 patients in the study, 19 were males and 13 were females. The mean age was 39 years (range: 22–70 years). Twenty-seven of the thirty-two patients (84.3%) had the dominant side fractured. We had eight cases of C2 type; five cases of C1 and A2 type; four cases of B2 type; three cases each of B3, B1, and A1 type; and one case of A3 type of fracture. The mean surgical time was 91.5 minutes (range: 70–120 minutes) and mean radiation exposure was 160.3 seconds (range: 100–220 seconds). The mean radiological fracture union time was 12.9 weeks (range: 10–20 weeks). Shoulder function was excellent in 27 cases (84.3%) and good in remaining 5 cases (15.6%) on the UCLA score. Elbow function was excellent in 26 cases (81.2%), good in 5 cases (15.6%), and fair in 1 case (3.1%) who had an associated olecranon fracture that was fixed by tension band wire in the same sitting.

Conclusion:

MIPO of the humerus gives good functional and cosmetic results and should be considered one of the management options in the treatment of humeral diaphyseal fractures.

An international,cross-sectional survey of the management of Vancouver type B1 periprosthetic femoral fractures around total hip arthroplasties

IntroductionThe incidence of periprosthetic femoral fractures around total hip arthroplasties is increasing. Fractures around a stable implant stem (Vancouver type B1) are among the most common of these fractures. Various fixation strategies for Vancouver type B1 periprosthetic fractures have been reported in the literature; however, little high-level evidence exists. This study was designed to determine the current management strategies and opinions among orthopaedic surgeons treating Vancouver type B1 periprosthetic femoral fractures, and to evaluate the need for a large prospective randomized controlled trial for the management of these injuries.MethodsOrthopaedic surgeon members of the Orthopaedic Trauma Association (OTA), the Canadian Orthopaedic Association (COA), and the Hip Society were invited to participate in a 51-item web-based survey surrounding the management of periprosthetic femoral fractures around total hip replacements, as well as the perceived need for future research in this area. Responses were summarized using proportions, and further stratified by practice type, case volume, surgeon age, and fellowship training.ResultsFor Vancouver type B1 fractures, open reduction and internal fixation (ORIF) with locked plating was favoured slightly over ORIF with cable plating ± cortical strut allograft (51.1% versus 45.5%). When compared to cable plating with cortical strut allograft, respondents believed that isolated locked plating resulted in lower nonunion and reoperation rates, but similar infection and malunion rates. Subgroup analyses revealed that practice type, surgeon age, case volume, and fellowship training influenced surgeons’ management of periprosthetic femoral fractures and beliefs regarding complications. There is high demand for a large prospective randomized controlled trial for Vancouver type B1 fracture fixation.ConclusionsConsensus surrounding the management of Vancouver type B1 periprosthetic femoral fractures is lacking, and there is a perceived need among orthopaedic surgeons for a large prospective randomized controlled trial in order to define the optimal management of these injuries.     

Malalignment after minimally invasive plate osteosynthesis in distal femoral fractures

IntroductionAlthough minimally invasive plate osteosynthesis (MIPO) is a preferred operative treatment for fractures of the distal femur, malalignment is a significant concern because of indirect reduction of the fracture. The purpose of this study, therefore, was to evaluate radiologic alignment after MIPO for distal femoral fractures.Patients and methodsOf the 138 patients with fracture of the distal femur who underwent MIPO, we enrolled 51 patients in whom bilateral rotational alignment could be assessed by postoperative computed tomography (CT). The patients included 32 men and 19 women, with a mean age of 54.3 years. Thirteen patients had femoral shaft fractures (according to the AO/OTA classification: 32-A, n = 2; 32-B, n = 6; 32-C, n = 5), whereas 38 patients had distal femoral fractures (33-A, n = 7; 33-C, n = 31). Coronal and sagittal alignments were assessed using simple radiography, whereas rotational alignment was assessed using CT. According to the difference between the affected and unaffected sides, we divided the patients into satisfactory and unsatisfactory groups (reference point of 8°, using Handolin’s classification). Thereafter, we determined which factors can lead to malalignment, including fracture location (distal femoral shaft fracture or metaphyseal fracture), fracture pattern (simple fracture, n = 15; complex fractures, n = 36 patients), coronal and sagittal alignments, and combined ipsilateral long bone fractures.ResultsCoronal and sagittal alignment were satisfactory in 96.2% (average, 2.8°) and 98% (average, 2.2°), respectively, whereas the rotational alignment was satisfactory in 56.9% of patients. Leg length discrepancy was satisfactory in 92.3% of the patients (average, 10.9 mm). Concerning rotational malalignment, an unsatisfactory result was obtained in 48.6% of subjects with complex fractures and 26.7% of subjects with simple fractures (p = 0.114). No significant correlation was noted between the angular deformity in the coronal and sagittal planes and the degree of rotational alignment (p = 0.607 and 0.774, respectively).ConclusionsRegardless of the fracture pattern, rotational malalignment may occur at an extremely high rate after MIPO for fractures of the distal femur.     

Failed osteosynthesis of cemented B1 periprosthetic fractures

BackgroundPeriprosthetic fractures about the hip are increasingly common. The literature estimates a failure rate of approximately 10% in Vancouver B1 type fractures which have undergone fixation. There is currently no guidance available on the next step of management for this patient group. This study presents a series of nine Vancouver B1 fractures with failed osteosynthesis and proposes that repeated fixation has poorer results than revision.MethodsA total of nine patients (five women, four men) with a mean age of 71.2 years (52–83) underwent operative treatment for failed osteosynthesis of periprosthetic fractures of Vancouver type B1. Three patients were revised to a long revision stem while six patients had repeated osteosythesis. Failure was defined as the need for further operative intervention.ResultsThe three patients revised to a long revision stem at first failure of osteosynthesis required no further surgical intervention. All six patients who had repeat osteoynthesis failed again. Five patients were subsequently successfully treated with revision of the primary stem, three were revised to a long revision stem while two patients required proximal femoral replacement. One patient died prior to revision. The mean follow up following initial B1 fracture was 49.3 months and following definitive operative intervention was 37.7 months. Six patients had died at 1st July 2017.ConclusionFailed osteosynthesis of B1 fractures may necessitate revision rather than repeat fixation, regardless of how well fixed the stem appears. Revision to a long stem provided good results in this cohort.     

关于温哥华C型股骨假体周围骨折采用不同长度锁定钢板固定的生物力学研究

目的通过比较四种不同长度的锁定钢板在治疗温哥华C型股骨假体周围骨折的生物力学实验中的表现，来分析锁定钢板相对于股骨假体柄远端的位置与产生的刚度和应力集中情况的关系。 方法选取10对成人新鲜股骨标本，随机均分为四组，制作温哥华C型股骨假体周围骨折模型，以四种不同长度的锁定钢板固定：A组，钢板最近端双皮质锁定螺钉距离假体尖端1个股骨直径；B组，钢板最近端双皮质锁定螺钉与假体尖端平齐；C组，钢板最近端单皮质锁钉与假体尖端重叠1个股骨直径；D组，钢板最近端单皮质锁钉与假体尖端重叠2个股骨直径。分别进行轴向压载实验、扭转实验、内外四点侧弯实验及前后四点侧弯实验，记录各组数据并进行统计学分析；最后进行循环负载实验，记录骨折情况。 结果各组在各实验中表现出的刚度值有显著差异，D组刚度值最大（P<0.05）；在循环负载实验中，D组骨折线分布于股骨假体尖端、近端锁钉以及钢板远端附近，A、C组的骨折线集中在近端锁钉与股骨假体尖端之间，B组骨折线集中在股骨假体尖端与钢板顶端的线性区域内，结果显示D组应力集中程度比A、B、C三组低（P<0.05）。 结论在使用锁定钢板治疗温哥华C型股骨假体周围骨折时，随着钢板长度增加，内固定稳定性提高；锁定钢板与股骨假体柄尖端重叠固定不会增加应力集中，反而随着钢板与股骨假体重叠区域增加，应力显著分散。     

Locking plate osteosynthesis for Vancouver Type B1 and Type C periprosthetic fractures of femur: a report on 12 patients

Many methods have been described to stabilise periprosthetic fractures around a total hip arthroplasty. Locking plate fixation offers increased angular stability and, theoretically, better fixation in osteoporotic bone. This study presents our results with the use of locking plate fixation for Vancouver Type B1 and Type C periprosthetic fractures following total hip arthroplasty (THA). Twelve patients underwent fixation of periprosthetic fractures with either a locking compression plate (LCP) or a distal femur less invasive stabilisation system (LISS). There were six Type B1 and six Type C fractures. One patient died soon after surgery. The mean follow-up was 13.9 months (range 12-18 months). The fracture healed in 10 of the remaining 11 patients with a median time to union of 4.8 months. There was one implant failure prior to fracture healing and one implant failure after fracture healing. Both were attributed to technical errors. Seven patients returned to their previous level of mobility. Two patients required the use of one walking stick after fracture healing, but had been able to walk unaided before their fall. One patient required two sticks, after previously requiring only a single stick. There were no infections. Our experience encourages us that locking plates have a role to play in managing periprosthetic fractures around a stable femoral stem, especially in patients with poor soft tissue and osteoporosis.     

Management of periprosthetic femur fractures with a first generation locking plate

Periprosthetic femoral fractures associated with well-fixed total hip or total knee prostheses present a challenging management problem as these injuries typically occur in osteoporotic bone. Conventional management entails extensive periosteal stripping to allow for plate fixation. We reviewed a consecutive series of patients who sustained fractures associated with a well fixed total knee prosthesis, a total hip prosthesis, or both. Twenty four patients with a mean age of 69.4 years were included. All patients underwent fixation via percutaneous insertion techniques with a first generation locking plate and screws (LISS--Less Invasive Skeletal Stabilization, Synthes, Paoli, PA). Three patients sustained fractures distal to a well-fixed total hip prosthesis, eighteen fractures occurred above a well-fixed total knee femoral component, and three were interprosthetic. The mean length of time from the index procedure to fracture was 76 months, range (2-172 months). Blood loss was minimal in each case, with a mean operative time of 90 min (range 60-120 min). Twenty one of twenty four went on to unite at a mean 6.2 months (range 3-19 months). Three patients underwent further surgery. One failure of fixation was encountered. Percutaneous fixation is technically demanding as it requires stable fixation without direct visualisation of the fracture site or the entire fixation device. Our results suggest percutaneous fixation with the LISS plate is an effective although technically demanding method of treatment. Complication rates were comparable to existing reports of this treatment method, and appear to be improved over traditional methods of fixation.     

锁定加压钢板在四肢骨折中的应用

目的探讨正确把握锁定加压钢板(LCP)治疗四肢骨折的原则。方法2002年3月～2005年12月应用LCP治疗150例四肢骨折患者,其中肱骨近端骨折45例,前臂尺桡骨骨折51例,胫腓骨骨折54例。术后4周内每周随访1次,4周后每个月随访1次。观察有无内固定松动、断裂、感染及患肢力线改变等情况发生。结果所有患者获平均14个月(4～20个月)随访。150例患者均在预期的时间内获骨性愈合,并获得满意的活动度,未出现断钉及内固定松动等并发症,仅2例患者出现切口感染。所有患者均未予以植骨。结论LCP是治疗长骨干骨折及近关节处骨折较理想的内固定方式,尤其适用于老年骨质疏松患者,术中应正确放置钢板位置,选择合适的钢板长度及螺钉数目,重视微创理念。     

Locking compression plate versus revision-prosthesis for Vancouver type B2 periprosthetic femoral fractures after total hip arthroplasty

IntroductionRevision arthroplasty is currently the recommended treatment for periprosthetic femoral fractures after primary total hip arthroplasty (THA) and stem loosening (Vancouver B2). However, open reduction and internal fixation (ORIF) utilizing locking compression plate (LCP) might be an effective treatment with a reduced surgical time and less complex procedure in a typically elderly patient collective with multiple comorbidities. The purpose of this study was to compare the functional and radiographic outcomes in two cohorts with Vancouver B2 periprosthetic femoral fractures after primary THA, treated either by ORIF with LCP fixation, or by revision arthroplasty utilizing a non-cemented long femoral stem.Materials and Methods36 patients with Vancouver B2 periprosthetic femoral fractures following THA, who had been treated between 2000 and 2014, were reviewed. Eight fractures were treated with LCP fixation, fourteen fractures with the first-generation revision prosthesis (Helios^®), and fourteen fractures with the second-generation revision prosthesis (Hyperion™). The patients were assessed clinically with the Parker mobility score and radiographically.ResultsA total of ten males and 26 females formed the basis of this report with an average age of 81years (range, 64 to 96 years). All fractures treated with LCP fixation alone healed uneventfully and there were no signs of secondary stem migration, malalignement or plate breakage. The average surgical time was shorter in the ORIF cohort; however, the results were not statistically significant. The postoperative Parker mobility score at latest follow-up showed no difference between the groups.ConclusionsAccording to the results of the current study, we conclude that the use of LCP fixation can be a sufficient option for the treatment of Vancouver B2 periprosthetic femoral fractures correspondingly with femoral stem loosening.

Early experience with the use of trochanteric reattachment plate for the treatment of Vancouver type B 1 periprosthetic hip fractures

ObjectiveThe purpose of our study is to study the usefulness of trochanteric reattachment plate in the management Vancouver type B 1 periprosthetic femur fractures.MethodsWe describe a case series of 15 (12 F: 3 M) Vancouver type B 1 fracture fixed with trochanteric reattachment plate with 3 years follow up. Patients with Vancouver A, B2, B3 and C fractures were excluded in the study. Clinical and radiological assessment of patients was done at 1, 3, 6, 9, 12, 24 and 36 months. The parameters evaluated were fracture union, Harris hip score and post-operative complications if any.ResultsPatients mean age was 74 years (range 58–84). Eleven patients were operated with cemented hemiarthroplasty while 4 patients had total hip arthroplasty done before. Operation time mean was 137.2 min and mean surgical blood loss was 522.66 ml. All the patients achieved radiological union of the fracture at mean of 14.13 weeks. Mean Harris hip Score was 82 at 36 months follow up. 13 out of 15 hips (86.67%) showed good clinical results and 2 patients (13.33%) showed fair result. All the patients returned to their pre injury activities of daily living.ConclusionOperative fixation of Vancouver type B 1 periprosthetic fractures is a challenge for an orthopedic surgeon. Open reduction and internal fixation of these fractures using of trochanteric reattachment plate incorporating screws and cerclage wires through the plate provides good outcome in these patients. Use of this plate offers the surgeon stability against shearing as well as rotational forces.

Minimally invasive plate osteosynthesis using posterolateral approach for distal tibial and tibial shaft fractures

ObjectiveThe objective of the study was to evaluate the effectiveness of the posterolateral minimally invasive plate osteosynthesis (MIPO) method for managing distal tibial or tibial shaft fractures with severe anterior and medial soft tissue injuries.Materials and methodsFive consecutive patients with three distal tibial and two tibial shaft fractures (three open fractures) at a level-1 trauma and tertiary referral center were retrospectively reviewed. All patients were definitively treated and followed to bone union. Main outcome was measured by American Orthopaedic Foot and Ankle Society (AOFAS) ankle–hindfoot score, complications, and bone union on radiographs.ResultsThe average follow-up period was 15.8 months (range, 12–24 months). The average AOFAS score was 88.2 (range, 81–90). There were no complications, such as incision breakdown, deep infection, or impingement of the flexor hallucis longus tendon. Bone union was achieved in all cases.ConclusionsPosterolateral MIPO is a feasible option when treating these fractures, especially in cases with severe anterior and medial soft tissue injuries.
