Extensively coated revision stems in proximally deficient femur: Early results in 15 patients

Background:

Hip replacement following failed internal fixation (dynamic hip screw for intertrochanteric fractures) or previous hip arthroplasty presents a major surgical challenge. Proximal fitting revision stems do not achieve adequate fixation. Distal fixation with long-stemmed extensively coated cementless implants (like the Solution™ system) affords a suitable solution. We present our early results of 15 patients treated with extensively coated cementless revision stems.

Materials and Methods:

Fifteen patients with severely compromised proximal femora following either failed hip arthroplasty or failed internal fixation (dynamic hip screw fixation for intertrochanteric fractures) were operated by the senior author over a two-year period. Eight patients had aseptic loosening of their femoral stems following cemented hip replacements, with severe thinning of their proximal cortices and impending stress fractures. Seven had secondary hip arthritis following failure of long implants for comminuted intertrochanteric or subtrochanteric femoral fractures. All patients were treated by removal of implant (cemented stems/DHS implants) and insertion of long-stemmed extensively coated cementless revision (‘Solution™ DePuy, Warsaw (IN), US’) stems along with press-fit acetabular component (Duraloc Cup, DePuy, Warsaw (IN), US). All eight hip revisions needed extended trochanteric osteotomies.

Results:

All patients were primarily kept in bed on physiotherapy for six weeks and then gradually progressed to weight-bearing walking over the next six to eight weeks. The Harris Hip Scores and patient satisfaction were used for final evaluation. We achieved good results in the short term studied. In our first three patients (all following failed cemented total hip replacements), we resorted to cerclage wiring to hold osteotomised segments (done to facilitate stem removal). The subsequent 12 proceeded without the need for cerclage wiring. One patient had a intraoperative severe comminuted fracture extending into the supracondylar region while hammering in the stem. Post cerclage wiring, she was put on a long knee brace and her mobilization was delayed to 12 weeks.

Conclusions:

The extensively coated cementless (‘Solution™’) femoral stem provides a reasonable ‘solution’ to the deficient femur in hip revision. The proximal femoral deficiences can be relatively easily bypassed and distal fixation can be achieved with this stem. Extreme care needs to be taken to avoid fractures and penetration of the femoral shaft, which can, however, be managed by cerclage wiring. Principles of a successful outcome include preservation of the functional continuity of the abduction apparatus, care to recognize and prevent distal extension of fracture while inserting the stem (preemptive cerclage wiring) and supervised rehabilitation.     

The Influence of Dorr Type and Femoral Fixation on Outcomes Following Total Hip Arthroplasty for Acute Femoral Neck Fractures: A Multicenter Study

BackgroundThe American Academy of Orthopaedic Surgeons guidelines report moderate evidence for cementing femoral stems for hip fractures, mainly derived from hemiarthroplasty literature. This is the first large, nonregistry study examining the influence of femoral fixation, implant type, patient characteristics, and radiographic factors on outcomes after total hip arthroplasty (THA) for acute femoral neck fractures.MethodsA multicenter retrospective study was performed of 709 THA cases (199 cemented, 510 cementless) for femoral neck fractures from 2006 to 2020 at three large academic institutions. Demographics, perioperative characteristics, and radiographs were reviewed. Kaplan-Meier survivorship curves were generated for multiple outcomes. Univariate and multivariate analyses were performed with P ≤ .05 denoting significance.ResultsCementless stems had a higher all-cause aseptic femoral revision rate (5.1 versus 0.5%, P = .002) and periprosthetic femoral fracture rate (4.3 versus 0%, P = .001). Each successive Dorr type had a higher fracture rate with cementless implants: 2.3%, 3.7%, and 15.9% in Dorr A, B, and C, respectively (P < .001). Logistic regression analyses confirmed that cementless stems (P = .02) and Dorr C bone (P = .001) are associated with periprosthetic fractures; collared implants and prophylactic cables did not protect against fractures. There was no difference in rates of dislocation, septic revision, or mortality between groups.ConclusionCementless stems during THA for femoral neck fractures have a higher aseptic femoral revision rate, specifically for periprosthetic fractures. Dorr C bone was particularly prone with an alarmingly high fracture rate. All fractures occurred in cementless cases, suggesting that cemented stems may minimize this complication.Level of EvidenceIII.     

Femoral component fixation with and without intramedullary plug A 6-year follow-up

A total of 113 patients underwent a cemented total hip replacement (THR) operation involving femoral component fixation either without the use of a distal intramedullary plug (n = 57, group 1) or with the plug (n =56, group 2). We studied the femoral component fixation radiographically at on average 6 years after THR. The cement coating was assessed as technically good in 86% and 95% of groups 1 and 2, respectively. There was radiographically diagnosable loosening of the femoral component at the follow-up in 25 cases in which stems were inserted without the intramedullary plug, and in 6 cases in those with the plug (P < 0.0008), and the mean subsidence of the femoral component was 5 mm in group 1 and 1.5 mm (P < 0.0003) in group 2, respectively. Osteolytic changes around the femoral component were noticed in both groups in equal numbers and with no statistical difference. The use of a distal intramedullary plug in the cementation of the femoral stem results in a better cement coating, reduces femoral component subsidence and ameliorates the loosening rates.

Vancouver B2 Peri-Prosthetic Fractures in Cemented Femoral Implants can be Treated With Open Reduction and Internal Fixation Alone Without Revision

BackgroundThe aim of this study is to assess the outcomes of 52 consecutive Vancouver B2 peri-prosthetic fractures around cemented polished double-tapered stems treated by open reduction and internal fixation in 2 trauma centers in 2 countries.MethodsOutcomes included modified Harris Hip Score (mHHS), Harris Pain Score, and return to pre-injury mobility. Fracture healing was assessed; implant subsidence measured and complications including re-operations reported.ResultsNo patient was lost to follow-up. Median patient age at operation was 82 years (range 43-98); Harris pain scores showed minimal pain (median 42, range 10-44) at latest follow-up. Median total subsidence at 1 year was 1.1 mm (range 0-5.4), the majority of which occurred within the cement mantle. No subsequent femoral stem revision was required (median 2.9 years, 0-10); however, there were 3 re-operations: 1 re-operation for pre-existing recurrent dislocation involving head liner exchange and 2 for repeat fixation due to metal fatigue. Two additional fractures occurred below the new plating, requiring further plating whilst still retaining the original stems.ConclusionAnatomical reduction and open reduction and internal fixation of Vancouver B2 peri-prosthetic fractures should be considered as an appropriate treatment solution for frail elderly patients with a peri-prosthetic fracture around cemented polished double-tapered stems.     

Outcome of total hip arthroplasty as a salvage procedure for failed infected internal fixation of hip fractures

Background:

Failed infected internal fixation produces significant pain and functional disability. In infected internal fixation of hip fractures with partial or complete head destruction, total hip arthroplasty (THA) can be technically challenging; however, it restores hip biomechanics. The present study is to evaluate the results and assess the complications of THA following failed infected internal fixation of these fractures.

Materials and Methods:

A retrospective review of prospectively collected data in a tertiary healthcare center was performed of 20 consecutive patients of THA following failed infected internal fixation operated between September 2001 and November 2007. There were 11 dynamic hip screw failures for intertrochanteric fractures, 6 failed osteotomies following transcervical fractures, and 3 failed screw fixations for transcervical fractures.

Results:

The average age of the patients was 48.5 years (range 28-70 years) and the average followup period was 6.5 years (range 3.5-10.5 years). An indigenously designed cement spacer was used in a majority of patients (n = 15). The custom-made antibiotic impregnated cement spacer was prepared on-table, with the help of a K-nail bent at 130°, long stem Austin Moore''s prosthesis (n=1), Charnley''s prosthesis (n=1), or bent Rush nail (n=1). The antibiotic mixed cement was coated over the hardware in its doughy phase and appropriately shaped using an asepto syringe or an indigenously prepared spacer template. Nineteen of the 20 patients underwent two-stage revision surgeries. The average Harris hip score improved from 35.3 preoperatively to 82.85 postoperatively at the last followup. A significant difference was found (P < 0.0001). None of the patients had recurrence of infection.

Conclusions:

The results were comparable to primary arthroplasty in femoral neck fractures. Thus, THA is a useful salvage procedure for failed infected internal fixation of hip fractures.     

Diaphyseal locking hip arthroplasty for treatment of failed fixation of intertrochanteric hip fractures

Between 1997 and 2004, 18 patients (8 men and 10 women, with a mean age of 73.2 years) with failed treatment of intertrochanteric hip fractures underwent hip arthroplasty as salvage procedures at our institution. Cementless, 5/8-porous coated, 6-in. primary diaphyseal locking femoral stems were used. Prospective follow-up ranging from 2 to 5 years (mean, 37.1 months) showed improvement of hip function without prosthesis loosening. Complications included 1 case of postoperative infection, 2 cases of dislocation, and 2 cases of stem subsidence. The clinical results were satisfactory. The 5/8-porous coated, 6-in. cementless femoral stems could be used in the salvage procedures for failed fixation of intertrochanteric hip fractures.     

股骨近端骨折治疗失败的原因分析及挽救性全髋关节置换

目的分析股骨近端骨折治疗失败的原因,探讨补救性全髋关节置换术(THR)的疗效。方法2002年2月～2005年4月,对23例股骨近端骨折治疗失败的患者(股骨颈骨折17例,股骨转子部骨折5例,股骨头骨折1例)进行回顾性研究,分析其前期治疗失败的原因,总结此23例患者进行补救性THR后的疗效。结果股骨近端骨折治疗失败的主要原因是骨折后复位不良、内固定方式选择不当或技术错误。21例患者获平均32个月(8～46个月)随访。无感染、脱位及假体周围骨折等并发症发生。21例患者髋关节功能均有改善,Harris评分由术前平均48．3分提高到术后87．6分。结论骨折复位、内固定方式或固定技术对股骨近端骨折的治疗非常重要。老年患者的骨质疏松和年轻患者的高能量损伤也增加股骨近端骨折治疗的难度。对于股骨近端骨折治疗失败的患者,进行补救性的THR重建髋关节功能临床疗效满意。

目的观察人工髋关节置换治疗股骨粗隆间骨折内固定失败患者的临床疗效。方法对2007年6月至2013年6月收治的21例股骨粗隆间骨折内固定失败的患者采用人工髋关节置换,并随访其疗效。本组21例21髋,其中20例采用全髋关节置换,1例采用人工双动股骨头置换。年龄40~79岁,平均62.8岁。无一例术中发生不良反应,术后均在2~3 d下床活动,无肺炎、褥疮等并发症发生。结果随访时间5~48个月,平均15.6个月。本组病例均伤口愈合良好,未发生假体下沉、松动现象,部分患者假体长度未超过远端螺钉孔,但无应力骨折发生。术后早期脱位1例,复位并行前方松解后未再次脱位。术后行走功能恢复正常(Harris评分平均术前43.2分,术后84.5分)。结论人工关节置换治疗股骨粗隆间骨折内固定失败患者,可早期下地功能锻炼,减少卧床时间及并发症的发生,有利于早期功能恢复,远期疗效需要进一步观察。     

Total Hip Arthroplasty After Failed Internal Fixation of Proximal Femoral Fractures

Between February 1987 and October 2008, we performed 102 total hip arthroplasties (THAs) after failed internal fixation of a prior hip fracture. There were 39 intertrochanteric fractures and 63 femoral neck fractures. Etiology of failure included 35 cases of osteonecrosis, 32 cases of arthritis, 25 cases of early failure of fixation, and 10 cases of nonunion. There were 12 patients who had early surgical complications related to the procedure (11.8%, 12/102). These included 5 patients who had dislocations (4.9%), 4 periprosthetic fractures (3.9%), 2 hematomas (2.0%), and 1 infection (1%). Of these 102 THAs, 50 were available for at least 2 years of follow-up (mean, 3.2 years). At a minimum 2-year follow-up, THA after failed internal fixation of hip fracture in these patients was clinically successful with an elevated risk of periprosthetic fracture and dislocation.     

Operative treatment of hip fractures in patients receiving hemodialysis

Fifteen hips in 13 patients with hip fracture were treated in patients receiving hemodialysis for chronic renal failure. There were four intertrochanteric and 11 femoral neck fractures. 10 of the 11 femoral neck fractures and one of the four intertrochanteric fractures were treated with cemented bipolar hemiarthroplasty. Two intertrochanteric fractures fixed with sliding compression screws. External fixation was used for stabilization in two patients who had femoral neck and intertrochanteric fractures. Two intertrochanteric fractures that were treated with sliding hip screw showed radiological union postoperatively at the 6th month. Of the 11 hemiarthroplasty, four hips developed aseptic loosening (36%). According to Harris hip score grading system, three (37.5%) poor, two (25%) fair, two (25%) good and one (12.5%) case had excellent outcome in the hemiarthroplasty group. The survival of dialysis patients with a hip fracture is markedly reduced. Initial treatment of hemiarthroplasty allows early mobilization and prevents revision surgery.     

Proximal Femoral Plate,Intramedullary Nail Fixation Versus Hip Arthroplasty for Unstable Intertrochanteric Femoral Fracture in the Elderly: A Meta-analysis

IntroductionMultiple operative modalities are available for management of unstable intertrochanteric femoral fractures. This meta-analysis was conducted to find out if there is superiority of surgical fixation by proximal femoral plate or surgical fixation by intramedullary nail over hip arthroplasty for management of unstable intertrochanteric femoral fractures in the elderly.MethodsA search for relevant studies that published from January 2000 to November 2018 through the electronic literature database of Cochrane library, Medline, Trip Database and Wiley online library.ResultsA total of 19 studies including 14 prospective RCTs, and five retrospective studies. This meta-analysis showed that nail group had shorter operative time than plate group (P < 0.0001), and less blood loss than the plate and arthroplasty groups (P < 0.0001), cut-out was higher in nail group than the plate group (P < 0.0001), mortality rate was higher in hip arthroplasty compared to other groups (P < 0.0001), Harris hip score within 6 months of the operation was higher in the arthroplasty group compared with the nail and plate groups, while within 1 year of the operation, nail group had higher Harris hip score than arthroplasty group (P < 0.0001).ConclusionsThis meta-analysis suggested that the intramedullary nail fixation method is a preferred method for management of unstable intertrochanteric femoral fractures in the elderly over hip arthroplasty and proximal femoral plate fixation.Supplementary InformationThe online version contains supplementary material available at 10.1007/s43465-021-00426-1.     

偏心固定与髓内固定治疗股骨转子间骨折的病例对照研究

Increased Mortality with the Use of Cementless Fixation for Femoral Neck Fractures: Analysis of 5883 Hip Arthroplasty Cases

BackgroundThe use of cemented fixation for hip arthroplasty for femoral neck fractures has been advocated to limit the postoperative and intraoperative risk of periprosthetic fractures. However, there are concerns with the potential effects of cementing on patient mortality, particularly at the time of cementation.MethodsThis study examined the mortality rates of cemented compared to cementless hip arthroplasty fixation in a group of 5883 femoral neck fracture patients from 2001 to 2017. The data were derived from large administrative databases and census data. Confounders were identified and controlled with a multivariate analysis. The data were also stratified into 2 time frames, 2001-2008 and 2009-2017, to determine if there was an effect of more recent improvements in patient care or implant technology.ResultsCemented fixation had a statistically significant reduction in mortality rates at 30, 90, and 365 days after surgery. There was no difference in mortality in 0, 1, or ≤7 days after discharge or during the admission. The mortality rate decreased but was still significantly increased with cementless fixation when the subjects were grouped from 2001 to 2008 and 2009 to 2017.ConclusionBased on this evidence, the cemented fixation of hip arthroplasty should be considered for patients with femoral neck fractures.     

Femoral Fixation Methods in Hip Resurfacing Arthroplasty: An 11-Year Retrospective Comparison of 4013 Cases

BackgroundThe optimal femoral fixation method remains unclear. To evaluate the role of femoral fixation techniques in hip resurfacing, we present a comparison of 2 consecutive groups: group 1 (739 hips) with cemented femoral components; group 2 (3274 hips) with uncemented femoral components.MethodsWe retrospectively analyzed our clinical database to compare failures, reoperations, complications, clinical results, and radiographic measurements. Groups were consecutive, so cemented cases had longer follow-up. However, all patients from both groups were at least 2 years out from surgery. Two-year clinical and radiographic data were compared. Longer-term comparison data as well as Kaplan-Meier implant survivorship curves specifically focusing on femoral failure modes were analyzed.ResultsKaplan-Meier 10-year implant survivorship using nontraumatic femoral failure as an end point was 98.9% for the cemented and 100% for the uncemented femoral component. The uncemented, group 2 cases showed a significantly lower raw failure rate (1.1% vs 4.6%), 2-year failure rate (0.8% vs 2.8%), 2-year femoral failure rate (0.4% vs 0.9%), and a lower combined rate of femoral complications and failures (0.6% vs 1.8%). In cases that did not fail, patient mean clinical scores, pain scores, and combined range of motion were all significantly better for group 2.ConclusionWe have demonstrated that in the fully porous-coated ReCap device, uncemented femoral fixation is superior to cemented fixation at 11 years follow-up (0.0% vs 1.1% late femoral loosening) in this single-surgeon cohort. Early femoral fractures also reduced from 0.8% to 0.3%, but this may be partially or completely due to a new bone density management program. This study demonstrates better femoral implant survivorship for the uncemented device compared to the cemented femoral resurfacing component for this implant design.     

Cement augmentation of intertrochanteric fracture fixation:A cadaver comparison of 2 techniques

We evaluated 2 techniques of cement augmentation to enhance fixation of intertrochanteric hip fractures. 4 fixation groups with 6 cadaver femurs in each group were compared: stainless steel lag screw and side plate with and without cement augmentation and a titanium alloy expandable dome plunger and side plate with and without cement augmentation. Gauges were used to establish the mechanical behavior of intact and then fractured femurs to simple uniaxial loads. Subsequent loading to failure allowed determination of maximum fixation strengths and modes of failure

Cement augmentation of each device increased its load to failure. There was no significant difference between the cemented lag screw and the uncemented dome plunger groups with average loads to failure of 4.0 × 10³ N. The greatest average load to failure was in the cemented dome plunger group (5.6 × 10³ N) with the lowest in the uncemented sliding hipscrew group (3.6 × 10³ N). Device cut-out as a cause of failure occurred mostly in the uncemented lag screw group. Sliding was enhanced by those methods that increased the fixation surface area within the femoral head, unless cement encroached in the region of the barrel-screw junction. Strain analysis showed that the dome plunger unloaded the bone at the calcar, regardless of cement augmentation, while the sliding hip screw allowed for compressive stresses in this area.

Proper cement augmentation increases load to failure and minimizes nail cut-out for both devices studied. However, the dome plunger, a device with a large fixation area in the femoral head, was equally effective and eliminated potential cement encroachment. Failure of intertrochanteric fracture fixation in osteoporotic bone may be minimized by an appropriate choice of device or cement augmentation.
