The feasibility of a novel 3D-Printed patient specific cutting guide for extended trochanteric osteotomies. 3D Print Med 2024; 10:7. [PMID: 38427157 PMCID: PMC10905807 DOI: 10.1186/s41205-024-00204-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 01/29/2024] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND The extended trochanteric osteotomy (ETO) is a surgical technique utilized to expose the intramedullary canal of the proximal femur, protect the soft tissues and promote reliable healing. However, imprecise execution of the osteotomy can lead to fracture, soft tissue injury, non-union, and unnecessary morbidity. We developed a technique to create patient specific, 3D-printed cutting guides to aid in accurate positioning of the ETO and improve osteotomy quality and outcomes. METHODS Patient specific cutting guides were created based on CT scans using Synopysis Simpleware ScanIP and Solidworks. Custom 3D printed cutting guides were tested on synthetic femurs with foam cortical shells and on cadaveric femurs. To confirm accuracy of the osteotomies, dimensions of the performed osteotomies were compared to the virtually planned osteotomies. RESULTS Use of the patient specific ETO cutting guides resulted in successful osteotomies, exposing the femoral canal and the femoral stem both in synthetic sawbone and cadaveric testing. In cadaveric testing, the guides allowed for osteotomies without fracture and cuts made using the guide were accurate within 6 percent error from the virtually planned osteotomy. CONCLUSION The 3D-printed patient specific cutting guides used to aid in ETOs proved to be accurate. Through the iterative development of cutting guides, we found that a simple design was key to a reliable and accurate guide. While future clinical trials in human subjects are needed, we believe our custom 3D printed cutting guide design to be effective at aiding in performing ETOs for revision total hip arthroplasty surgeries.

[PMID: 37893539 PMCID: PMC10608113 DOI: 10.3390/medicina59101822] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 09/25/2023] [Accepted: 10/06/2023] [Indexed: 10/29/2023]
Abstract
Background and Objectives: Implantation of a short femoral stem in revision total hip arthroplasty (rTHA) could reduce the perioperative time, soft tissue damage, and preserve the bone stock of the proximal femur. The objective of this study was to describe the clinical and radiographic outcomes after the use of short stems in rTHA with a follow-up of 1 to 5 years. Materials and Methods: This retrospective, single center, and observational study analyzed the data of 31 patients (12 female, 19 male) with a median (interquartile range) age of 68.2 years (61.2-78.4) and BMI of 26.7 kg/m2 (24.6-29.4) who received an uncemented short femoral stem in rTHA between 2015 and 2020. Clinical outcomes were extracted from medical reports and assessed using the modified Harris Hip Score (mHHS), the numerical rating scale (NRS) for pain and satisfaction, and the UCLA Physical Activity Score. Radiographs were analyzed for stem subsidence, fixation, and bone parameters. The Wilcoxon test was used for pre-post rTHA differences (p < 0.05); clinical relevance was interpreted based on effect sizes according to Cohen's d. Results: All the clinical outcome measures improved significantly (p ≤ 0.001) at follow-up compared to preoperative status, with large effect sizes (Cohen's d) ranging from 2.8 to 1.7. At the last follow-up, the median (interquartile) mHHS was 80.9 (58.6-93.5). Stem fixation was stable in all cases. Complications included stem subsidence of 3 mm (n = 1) and 10 mm (n = 1), heterotopic ossification Brooker stage III (n = 2), intraoperative femur perforation (n = 1), periprosthetic fracture Vancouver type A (n = 1), and dislocation (n = 2). Conclusions: The good clinical results in our selective study population of patients with mild to moderate bone deficiency, supported by large effect sizes, together with a complication rate within the normal range, support the consideration of short stems as a surgical option after a thorough preoperative analysis.

Clinical and Functional Outcomes of Extended Trochanteric Osteotomy in 2-Stage Revision Total Hip Arthroplasty for Periprosthetic Joint Infection: A Systematic Review and Meta-Analysis. J Arthroplasty 2023; 38:1900-1907. [PMID: 37001623 DOI: 10.1016/j.arth.2023.03.073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 03/04/2023] [Accepted: 03/24/2023] [Indexed: 05/01/2023] Open
Abstract
BACKGROUND Extended trochanteric osteotomy (ETO) has long been used in 2-stage revision surgeries of the hip, for both aseptic and septic indications. The purpose of this systematic review is to summarize the cumulative occurrence rates of the clinical and functional outcomes associated with the use of ETO in 2-stage revision total hip arthroplasty for periprosthetic joint infection. METHODS PubMed/MEDLINE and the Cochrane Database of Systematic Reviews databases were searched for articles published from January 1980 to January 2022 using the following keywords: "extended" AND "trochanteric" AND "osteotomy" AND "infection." Cumulative occurrence rates of outcomes and complications were calculated. A fixed-effects model and a 95% CI were applied. A P value of .05 was considered the significance threshold. RESULTS Nine studies were in full compliance with the inclusion criteria, with a total population size across all studies of 378. Union and infection eradication rates among studies were 95.1% (95% CI, 92.7-97.1, P = .018) and 94.0% (95% CI, 91.1-96.4, P = .089), respectively. Postoperation complications occurred in 15.34% of patients (95% CI, 10.34-21.22, P = .066). Occurrence rates for stem subsidence, dislocation, and femoral fractures were 6.2% (95% CI, 3.3-9.9, P = .187), 7.6% (95% CI, 4.8-10.9, P = .075), and 9.1% (95% CI, 5.8-13, P = .106), respectively. CONCLUSION With high rates of union and infection eradication, and low rates of postoperation complications, this study concludes the use of ETO in performing 2-stage revision total hip arthroplasty for the septic hip to be effective and safe.

Abstract
Extended trochanteric osteotomy (ETO) is an established method in revision total hip arthroplasty. Proximal migration of the greater trochanter fragment and the resulting non-union of the osteotomy remains a major problem, and several techniques have been developed to prevent its occurrence. This paper describes a novel modification of the original surgical technique in which a single monocortical screw is placed distally to one of the cerclages used for the fixation of the ETO. The contact between the screw and the cerclage counteracts the forces applied on the greater trochanter fragment and prevents trochanteric escape under the cerclage. The technique is simple and minimally invasive, does not require special skills or additional resources, or add to surgical trauma or operating time, and therefore represents a simple solution to a complicated problem.

Abstract
Osteotomy of the femur is necessary in some cases of primary/revision total hip arthroplasty (THA) procedure. There are two mainly used femur osteotomy methods in THA: greater trochanteric osteotomy and subtrochanteric osteotomy. Greater trochanteric osteotomy can improve hip exposure, provide greater stability against dislocation and favorably influence the abductor moment arm. Whether in the primary or revision THA, greater trochanteric osteotomy has its unique position. Subtrochanteric osteotomy adjusts the degree of femoral de-rotation and corrects the leg length. It is widely used in hip preservation and arthroplasty surgery. All osteotomy methods have specific indications, while nonunion is the commonest complication. In this paper, we analyze the greater trochanteric osteotomy and the subtrochanteric osteotomy in primary/revision THA and summarize the characteristics of different osteotomy methods.

[PMID: 36067886 PMCID: PMC10167626 DOI: 10.1016/j.arth.2022.08.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 08/24/2022] [Accepted: 08/27/2022] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND An extended trochanteric osteotomy (ETO) is a powerful tool for femoral component revision. There is limited evidence that directly supports its use in the setting of a periprosthetic joint infection (PJI). Cerclage fixation raises the theoretical concern for persistent infection. METHODS Our institutional database included 76 ETOs for revision hip arthroplasty between January 1, 2008 and December 31, 2019. The cohort was divided based on indication for femoral component revision: PJI versus aseptic revision. The PJI group was subdivided based on second-stage exchange versus retention of initial cerclage fixation. Operative time, estimated blood loss, complications, and rate of repeat revision surgery were evaluated. RESULTS Forty-nine patients (64%) underwent revision for PJI and 27 patients (36%) underwent aseptic revision. There was no significant difference in operative times (P = .082), postoperative complications (P = .258), or rate of repeat revision surgery (P = .322) between groups. Of the 49 patients in the PJI group, 40 (82%) retained cerclage fixation while 9 (18%) had cerclage exchange. Cerclage exchange did not significantly impact operative time (P = .758), blood loss (P = .498), rate of repeat revision surgery (P = .302), or postoperative complications (P = .253) including infection (P = .639). CONCLUSION An ETO remains a powerful tool for femoral component removal, even in the presence of a PJI. A multi-institutional investigation would be required to validate observed trends toward better infection control with cerclage exchange. Cerclage exchange did not appear to increase operative time, blood loss, or postoperative complication rates.

Comparison of Functional and Radiographic Outcomes Between Two Fixation Methods for Extended Trochanteric Osteotomy in Revision Total Hip Arthroplasty: A Retrospective Cohort Study. J Arthroplasty 2022; 37:1844-1850.

Abstract
BACKGROUND To compare the functional and radiographic outcomes between two fixation methods for extended trochanteric osteotomy (ETO) in revision total hip arthroplasty (rTHA). METHODS Included in this study were 64 patients who underwent ETO in rTHA using either claw-plate fixation (claw-plate group, n = 31) or cable-alone fixation (cable group, n = 33) in our hospital from 2008 to 2020. The functional and radiographic results and complications were compared between the groups during a mean follow-up period of 64 and 78 months. RESULTS The Harris hip score and visual analogue scale at the last follow-up improved significantly in both groups, showing no significant statistical difference between the two fixation methods. In the cable group, the mean abductor lever arm, the proximal migration, and medial migration in the affected hip were significantly decreased compared to those in the contralateral normal hip (P < .05), whereas in the claw-plate group no significant statistical differences were observed between two sides. No or slight limping occurred in 25 patients (81%) in the claw-plate group and 16 patients (48%) in the cable group (P = .007). A multiple logistic regression demonstrated that claw-plate fixation could reduce the incidence of postoperative moderate-to-severe limping. CONCLUSION Both claw-plate fixation and cable-alone fixation could improve the functional performance of rTHA with ETO, whereas claw-plate fixation could offer superior biomechanical results and gait improvement as compared with cable-alone fixation.

Extended Trochanteric Osteotomy Closure Performed Before or After Canal Preparation and Stem Impaction Does Not Affect Axial Stability. J Arthroplasty 2022; 37:S964-S970. [PMID: 34392990 DOI: 10.1016/j.arth.2021.07.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 07/02/2021] [Accepted: 07/23/2021] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND An extended trochanteric osteotomy (ETO) safely addresses femoral component removal during challenging revision total hip arthroplasty. However, no prior study has evaluated whether a difference in axial stability exists between ETO closure performed before (reconstitution) or after (scaffolding) canal preparation and stem impaction. We hypothesized that given the absence of clinical reports of outcome differences despite the wide use of both practices, no significant difference in the initial axial stability would exist between the 2 fixation techniques. METHODS ETOs were performed and repaired using the reconstitution technique for the 6 right-sided femora and the scaffolding technique for the six left-sided femora. The 195-mm long, 3.5°-tapered splined titanium monobloc stems were impacted into 6 matched pairs of human fresh cadaveric femora. Three beaded cables were placed in a standardized fashion on each specimen, 1 for prophylaxis against osteotomy propagation during reaming/impaction and 2 to close the ETO. Stepwise axial loading was performed to 2600 N or until failure, which was defined as subsidence >5 mm or femoral/cable fracture. RESULTS All specimens successfully resisted axial testing, with no stem in either ETO repair group subsiding >2 mm. The mean subsidence for the reconstitution group was 0.9 ± 0.4 mm, compared to 1.2 ± 0.5 mm for the scaffolding group (P = .2). CONCLUSION In this cadaveric model with satisfactory proximal bone stock, no difference existed between the reconstitution and scaffolding ETO repair techniques, and both provide sufficient immediate axial stability in a simulated revision total hip arthroplasty setting under physiologic loads.

Medicina (B Aires) 2022; 58:medicina58020237. [PMID: 35208559 PMCID: PMC8879778 DOI: 10.3390/medicina58020237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 01/29/2022] [Accepted: 02/02/2022] [Indexed: 11/16/2022] Open
Abstract
Background and Objectives: One of the most difficult aspects of hip revision is to remove the stem from the femoral canal with or without cement while maintaining the maximal amount of bone stock to obtain the best possible press-fit of the revision prosthesis. The transfemoral approach ensures direct access to the medullary canal so that the content removal is completed under direct control, while protecting the bone. This type of approach is particularly efficient for special conditions, such as deformation of the proximal femoral region, broken stems, or the presence of cement over a long distance distal to the prosthesis. The aim of this study was to evaluate the main advantages of transtrochanteric approach in hip revisions. Materials and Methods: Our series included 36 revisions performed using the transfemoral approach. We have analyzed the following postoperative radiological aspects: the length of the fixation zone distal to the osteotomized bone fragment (OBF), the gap between the OBF and the diaphysis, stem subsidence over time, and OBF consolidation. Results: The results were very good, both in terms of the rate of intraoperative complications and postoperative evolution. The fixation zone length was 4.2 cm on average (range: 2 to 5.8 cm). The distal gap between the OBF and the diaphysis was 1.2 cm on average (range: 0 to 2.3 cm). Stem subsidence was noted in four cases (11.1%). In all cases, stem subsidence occurred between three and six months and was 6 to 8 mm without affecting hip stability. OBF consolidation was radiologically confirmed for all cases at one year follow-up. Clinical assessment based on the Harris Hip Score showed an overall improvement from 43.2 preoperatively to 79.7 at 12 months and 83 at two years, respectively. The most important rate of progress was between 6 months and 12 months. Conclusions: The transtrochanteric approach has been shown to be very efficient for hip revisions. Understanding the hip biomechanics, applying a less aggressive surgical technique, and using efficient fixation methods such as cables significantly improved the results.

Abstract
INTRODUCTION Periprosthetic femoral fractures (PFF) are often the reason for revising total hip arthroplasty (RTHA). Converting these fractures into modified extended trochanteric osteotomy (mETO) facilitates stem revision. Modular revision stems are a common choice with good results. We present mid-term outcomes in patients undergoing RTHA for Vancouver B2/B3 PFF using a tapered, fluted modular stem with an mETO approach. MATERIALS AND METHODS A single-center analysis of patients with RTHA for Vancouver B2/B3 PFF using a single modular implant with mETO was performed (2007 - 2019). Clinical outcome (mobility, range of motion, function), radiological outcome (fracture healing, stem subsidence) and patient reported outcome measures (FJS-12, HHS, EQ-5D) were assessed. RESULTS Ninety-seven patients (mean age 78.1 years, BMI 25.8 kg/m2, 85.6% B2-fractures) were included; 80 patients had complete clinical and radiological follow-ups. Normal unaided gait without limping was achieved in 38/80 patients. After one year fracture / mETO healing occurred in 74/80 patients; 5.3 years after surgery, the respective FJS-12, HHS and EQ-5D (available in 34 patients) averaged 81.3 ± 30.2, 71.4 ± 18.7 and 0.8 ± 0.2. We documented 7 in-hospital deaths, 18.8% postoperative complications and 13.8% revisions with stem revisions being most commonly for subsequent PFF or subsidence. CONCLUSION Good clinical and radiological outcomes and rather low complication and revision rates (18.8% and 13.8%) were achieved. FJS-12 showed excellent results in patients undergoing RTHA for Vancouver B2/B3 PFF using a cementless, dual modular titanium revision stem and an mETO approach. Joint awareness was thereby similar to previously reported primary THA results at 5.3 years follow-up.

Abstract
PURPOSE The fully porous long stem could be used for diaphyseal locking and achieve bypass fixation in revision total hip arthroplasty (THA). This study evaluated long-term results for fully porous long stems made of titanium alloy in revision THA. METHODS Between 2003 and 2010, 45 consecutive femoral revisions were performed using fully porous long stems. Thirty-eight hips had complete clinical and radiographic data for a mean of 13.8 years (range, 10-16.7 years). Femoral bone loss was Paprosky type II in 14 hips, type IIIA in 18 hips, and type IIIB in six hips. Clinical results were analyzed using the Merle d'Aubigné and Postel scoring system. Femoral stress shielding was graded. Radiological loosening of the femoral component was evaluated. Kaplan-Meier survival analysis was performed with revision for any reason as the end-point. RESULTS Mean Merle d'Aubigné and Postel score improved significantly from 10.7 before revision to 14.5 at latest follow-up (p < 0.001). Third-degree stress shielding was found in seven hips, and fourth degree in 11 hips. Radiological femoral loosening occurred in one hip, which was revised. Another hip was revised for stem fracture. Kaplan-Meier cumulative survival rate was 94.7% at both ten and 15 years. CONCLUSION Although stress shielding is a concern with fully porous stems, this stem was useful in revision THA and provided satisfactory long-term results in hips with Paprosky types II, IIIA, and IIIB.

Abstract
Introduction The objective of this study was to assess if the fracture and/or non-union of extended trochanteric osteotomy (ETO) affected the behavior and survival of modular fluted and tapered distal fixation stems in revision total hip arthroplasties (rTHA). Methods We retrospectively analyzed 52 rTHA in 52 patients. Preoperative diagnoses were mechanical loosening (42 cases), septic loosening (8), periprosthetic fracture (1), and femoral stem fracture (1). According to the Paprosky classification, femoral bone stock deficiencies were 19 type-II, 26 type IIIA, and 7 type IIIB. We assessed the behavior of the osteotomy (union, fracture, migration) and the survival and behavior (integration and subsidence) of prosthetic femoral stems. Results ETO union and non-union rates were 84.61% (44 patients) and 15.38% (8 cases) respectively. There were twelve (23%) intra-operative fractures of the osteotomy fragment and 11 (21.15%) migrations (4.5 mm on average). We observed bone union in 39 (75%) stems and 13 (25%) stable fibrous unions. Nine (17.3%) stems subsided 7 mm (2-15 mm) on average before becoming stable. Stem subsidence and integration was not significantly affected by ETO fracture/no fracture or union/non-union. The postoperative Harris Hip Score (HHS) improved significantly as compared to the pre-operative HHS (38.41 ± 3.54 vs 85.29 ± 3.36; p < 0.01). Patients were followed up for 55 (24-100) months. The overall implant survival at the end of follow-up was 100%. Conclusions In this series, neither the non-union nor the intra-operative fracture of the ETO segment affected the behavior or medium-term survival of femoral stems.

Abstract
Introduction: Stem fracture is a rare complication of total hip arthroplasty (THA) using fully porous-coated femoral stems. Bilateral fractures in a single patient have not been previously reported. Case Report: A 48-year-old female underwent bilateral staged primary THA with fully porous-coated anatomic medullary locking femoral prostheses. She subsequently sustained stem fractures of her right and left prostheses in the 13thand 14thyears after their implantation, respectively. Conclusion: The bilateral nature of this rare complication in a single patient supports the notion that stem fracture results from a mismatch between the mechanical stresses encountered in vivo and the structural properties of small-diameter stems. Surgeons should be cognizant of this potential complication when evaluating patients at long-term follow-up with new-onset pain.

Abstract
Objective To investigate the early effectiveness of proximal femur reconstruction combined with total hip arthroplasty (THA) in the treatment of adult Crowe type Ⅳ developmental dysplasia of the hip (DDH). Methods Between May 2015 and March 2018, 29 cases (33 hips) suffering from Crowe type Ⅳ DDH were treated with proximal femur reconstruction combined with THA. Of the 29 cases, there were 6 males (7 hips) and 23 females (26 hips), aged from 24 to 74 years with an average age of 44.9 years. The preoperative Harris hip score was 44.0±12.0. Gait abnormalities were found in all of the 33 hips with positive Trendelenburg sign, and the lower limb discrepancy was (3.8±1.6) cm. Preoperative X-ray films and CT both indicated serious anatomical abnormalities, including complete dislocation of the affected hip with significant move-up of the greater trochanter, abnormal development of the femoral neck, abnormal anterversion angle and neck-shaft angle, dysplasia of proximal femur and dysplasia of medullary cavity. The operation time, intraoperative blood loss, transfusion rate, and complications were recorded. The Gruen and DeLee-Charnley zoning methods were used to evaluate the aseptic loosening of the prosthesis on X-ray films. The Harris score was used to evaluate hip function. The lower limb discrepancy was calculated and compared with the preoperative value. Results The operation time ranged from 80 to 240 minutes, with an average of 124.8 minutes. The intraoperative blood loss ranged from 165 to 1 300 mL, with an average of 568.4 mL. Seventeen patients (51.5%) received blood transfusion treatment. All the incisions healed by first intention without infection or deep vein thrombosis. All patients were followed up 19-53 months, with an average of 33 months. One patient had posterior hip dislocation because of falling from the bed at 4 weeks after operation, and was treated with manual reduction and fixation with abduction brace for 4 weeks, and no dislocation occurred during next 12-month follow-up. Two patients developed sciatic nerve palsy of the affected limbs after operation and were treated with mecobalamin, and recovered completely at 12 weeks later. Trendelenburg sign was positive in 3 patients and mild claudication occurred in 4 patients after operation. X-ray films showed that all the osteotomy sites healed at 3-6 months after operation, and no wire fracture was observed during the follow-up. The Harris score was 89.8±2.8 and lower limb discrepancy was (0.6±0.4) cm at last follow-up, both improved significantly ( t=-22.917, P=0.000; t=11.958, P=0.000). The prosthesis of femur and acetabulum showed no obvious loosening and displacement, and achieved good bone ingrowth except 2 patients who had local osteolysis in the area of Gruen 1 and 7 around the femoral prosthesis, but no sign of loosening and sinking was observed. Conclusion The treatment of Crowe Ⅳ DDH with proximal femur reconstruction and THA was satisfactory in the early postoperative period. The reconstruction technique of proximal femur can effectively restore the anatomical structure of proximal femur, which is one of the effective methods to deal with the deformity of proximal femur.

Abstract
BACKGROUND The efficacy of partial retention of well-fixed components during two-stage exchange for chronic total hip arthroplasty (THA) infection has remained unknown. METHODS A total of 14 patients with chronic infected THA were treated with damage control two-stage revision, including selective retention of the well-fixed femoral or acetabular component, aggressive debridement, antibiotic-laden cement spacer, antibiotic therapy, and delayed reimplantation. Indications for this treatment included chronic infected THAs with ingrown femoral or acetabular component and positive microbial growth with sensitive antibiotics. We excluded patients with acute infection; negative microbial growth; positive pathogen with high-virulence bacterial infections and multiple drug-resistant bacteria such as methicillin-resistant Staphylococcus aureus, fungi, and Mycobacterium tuberculosis; sinus formation; a prior failure for periprosthetic joint infection (PJI) treatment; and obvious bone resorption in both femoral and acetabulum side. During the study period, this represented 3.3% (14/425) of the patients treated for infected THA. Minimum follow-up was three years. None of the 14 patients in this series were lost to follow-up. Successful treatment was defined according to a modified Delphi-based international multidisciplinary consensus. RESULTS No repeated debridement and recurrence of infection occurred during the study period; no patient need chronic antibiotic suppression. Successful treatment of chronic PJI was achieved in all patients. Despite the high peri-operative complication rate, no severe consequences were observed. The mean Harris Hip Score was 86 (range, 82-92; SD, 3.3). CONCLUSIONS The selective partial implant retention two-stage revision for chronic PJI may be a treatment option in properly selected patients with low virulence bugs.

Abstract
Background The anterior cortical window technique was developed to facilitate stem removal in revision total hip arthroplasty (THA). In this technique, only the anterior cortex of the proximal femur is osteomized; the trochanter, lateral cortex, and medial cortex remain intact. Therefore, a new stem can be press-fitted into the femur and mediolateral stability can be obtained. However, the long-term results of revision THA using this technique are unknown. We report the outcome and survivorship at a minimum of 10-year follow-up. Methods From May 2003 to April 2006, 69 patients (75 hips) underwent revision THA using an anterior cortical window and a cementless distal interlocking stem. Of these, 50 patients (56 hips) were followed up for 10 to 13 years (mean, 11.5 years). There were 26 men (29 hips) and 24 women (27 hips) with a mean age of 51.2 years (range, 29 to 82 years) at the time of revision arthroplasty. We evaluated radiographs, Harris hip score, University of California at Los Angeles (UCLA) activity score, Koval category, and survivorship. Results Nonunion of the osteotomy occurred in one hip (2%). Five stems (8.9%) subsided 5 mm or more. At the final evaluation, the mean Harris hip score, UCLA activity score, and the Koval category were 82.5, 4.6, and 1.5, respectively. Survivorship with any operations as the end point was 80.4% and that with stem-revision as the end point was 91.1%. Conclusions With use of an anterior cortical window, a well-fixed stem can be easily removed, and a new stem can be inserted with firm mediolateral stability in the proximal femur in revision THA. We recommend using this technique instead of the extended trochanteric osteotomy in revision THA.

Abstract
BACKGROUND The effect of extended trochanteric osteotomy (ETO) with immediate cerclage wire fixation on the scene of chronic periprosthetic joint infection on infection eradication and the osteotomy healing remains unclear. METHODS One hundred seventeen patients who underwent two-stage revision total hip arthroplasty for chronic periprosthetic joint infection were enrolled in the study. The minimum follow-up was 2 years. Of these, 48 patients had underwent ETO and immediate cerclage wire fixation during the first-stage surgery, while 69 did not undergo ETO or any other osteotomy. In addition, 18 patients had underwent ETO in the second-stage reimplantation surgery. Repeated debridement, curative rate of infection, and complications were compared between the 2 groups. Meanwhile, osteotomy healing between the first and second osteotomy were also compared. RESULTS The repeated debridement rate and curative rate of infection were 2.1% and 95.8% in the ETO group, compared with 13.0% and 82.6% in the non-ETO group; there were significant difference between the 2 groups in these parameters (P = .037 and .030, respectively). Meanwhile, osteotomy healing rate was 93.8% in first-stage surgery with infection scene and 100% in second-stage surgery without infection; no significant difference was detected in osteotomy healing rate and time to healing (P = .278 and .803, respectively). The rate of complication was similar in both groups. CONCLUSIONS ETO combined with immediate cerclage wire fixation does not appear to reduce the rate of infection eradication. There was no harmful effect on complication rate and osteotomy healing.

Abstract
BACKGROUND The indications and technique for the transtrochanteric approach to the hip have evolved greatly since its initial popularization in the 1960s. The purpose of this systematic review was to assess current uses of this approach on the basis of indications, osteotomy technique, trochanteric fixation method, complications, and functional outcome. METHODS A comprehensive search of MEDLINE and Embase databases from January 2000 to July 2017 was performed in accordance with the PRISMA guidelines. Articles were divided into 3 major categories on the basis of the type of hip surgery performed: (1) primary arthroplasty, (2) revision arthroplasty, and (3) joint-preserving procedures. Patient data were then analyzed according to these 3 categories. RESULTS Seventy-six studies (5,028 hips), mainly of Level-IV evidence, were included. Four types of osteotomy were reported for a variety of indications. Rates of nonunion were 6.0% (303 of 5,028) across all studies, 4.2% (39 of 921) for primary arthroplasty, 6.7% (114 of 1,690) for revision arthroplasty, and 4.4% (56 of 1,278) for joint-preserving procedures. Rates of dislocation were 1.5% (14 of 921) for primary arthroplasty and 4.6% (77 of 1,690) for revision arthroplasty. The rate of osteonecrosis after joint-preserving procedures was 1.1% (14 of 1,278). Rates of deep infection were 1.1% (55 of 5,028) across all studies, 0.1% (1 of 921) for primary arthroplasty, 2.1% (36 of 1,690) for revision arthroplasty, and 0.6% (8 of 1,278) for joint-preserving procedures. CONCLUSIONS The transtrochanteric approach remains useful in cases requiring extensile exposure of the acetabulum or femoral medullary canal. However, trochanteric complications continue to pose a clinical challenge. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Femoral Bone Restoration Patterns in Revision Total Hip Arthroplasty Using Distally Fixed Modular Tapered Titanium Stems and an Extended Trochanteric Osteotomy Approach. J Arthroplasty 2018; 33:2210-2217.

Abstract
BACKGROUND Mechanical failure of modular revision stems is a serious complication in revision total hip arthroplasty. The lack of adequate osseous support to the proximal component, especially in cases of an extended trochanteric osteotomy approach, is considered a risk factor for stem failure. In this study, we analyze proximal bone regeneration patterns in patients undergoing revision total hip arthroplasty for aseptic stem loosening through an extended trochanteric osteotomy approach using an uncemented dual modular stem. METHODS Fifty-four patients treated for aseptic stem loosening were radiologically reviewed. The femur was divided according to the Gruen zones. Preoperative bone loss, formation of new cancellous bone, and presence of direct osseous contact to the stem were noted right away for each Gruen zone. The presence of osseous support at the modular junction and the proximal component were examined. RESULTS All patients showed restoration of proximal bone mass at final follow up. New bone formation was first seen in more distally located Gruen zones. Cases with longer proximal components had a trend toward earlier osseous support at the modular junction. Overall, 75% of patients showed osseous support at the modular junction 2 years after surgery. CONCLUSION Restoration of proximal bone occurs in a distal to proximal direction. Shorter proximal components require more time until osseous support to the modular junction is achieved, which may result in a higher risk of mechanical failure. Based on this study, bony support at the modular junction should not be expected in 25% of cases 2 years after surgery.

Abstract
Introduction: The trans femoral osteotomy was initially described by Wagner in 1987 and the extended trochanteric osteotomy (ETO) was described by Younger et al. in 1995 and is considered to be the gold standard technique for removal of well-fixed femoral stems in revision total hip arthroplasty (THA). The purpose of this report is:
to compare the different types of fixation metallic wires, cables, metallic reinforcement plate (MRP) we have used in revision THA where an ETO was performed; analyse the clinical and radiological outcomes of these devices at 1 year; analyse the complication.
Materialand method: It is a retrospective continuous monocentric series of 157 patients where an ETO was performed. It was fixed by an MRP in 17 patients, cables in 43, metallic wires in 97. The main outcome was the consolidation of the osteotomized femoral flap (OFF). Secondary outcomes were Postel Merle d’Aubigne score and complications occurred at 1 year follow up. Qualitative variable was presented as percentage, quantitative variables as mean or median, standard deviation and range. Result: 157 patients (73−46, 5% females) were included. Mean age at surgery was 66.7 year (sd = 10.63). Mean interval between index surgery and revision was 11.07 year (sd = 5.67). Causes for revision and bone defects were comparable. At 1 year OFF is healed without displacement in 82% with metallic wires, 70% with cables, 88% with MRP. Not significant. Discussion: Fixation of the femoral flap is a technical issue in ETO. Metallic wires and cables are the most commonly used to secure the fixation. Fixation with a metallic plate is reported in a few number of articles and may be helpful specially when a fracture of the OFF occurred during surgery.

Abstract
CASE A 65-year-old farmer re-presented 5 years after sustaining a midshaft prosthetic fracture of a previous long-stem revision hip replacement. He was treated with a proximal-loading short femoral stem, and did not require an extended trochanteric osteotomy for removal of the well-fixed distal implant. He was able to fully bear weight immediately postoperatively, and he remained pain-free without functional loss at the 42-month follow-up. CONCLUSION This use of a modern short-stem prosthesis is a treatment option for a potentially complex prosthetic fracture in highly active patients, and it reduces intraoperative complexity.

Abstract
BACKGROUND Femoral component revision is the treatment of choice for Vancouver type B2/B3 periprosthetic femur fractures (PFFs). The purpose of this study was to report the clinical outcome of revision total hip arthroplasty with the use of a modified extended trochanteric osteotomy (ETO) in PFF treatment. METHODS A total of 43 cases between 2000 and 2014 were analyzed. Clinical and radiographic evaluation was performed with a mean follow-up of 40 months. Patient survival after revision surgery, complications, radiographic outcomes, and quality of life and hip function were assessed. RESULTS Merle d'Aubignè and Postel score averaged 15, and mean postoperative Harris hip score was 70. Radiographic evaluation revealed that the ETO and fractures healed in all but 1 patient within 9 months. Component stability and apparent osseointegration were not coincident with healing of the osteotomy and fracture sites proximal to the inserted stem. Six patients (15%) developed postoperative complications, which included the following: 1 nonunion with progressive subsidence, 2 hip dislocations, 2 deep infections, and 1 breakage of the modular junction of the revision stem. CONCLUSION The modified ETO with a lateral approach to the hip for the treatment of PFF is compatible with fracture healing, a low dislocation rate, and good clinical results. However, component stability and apparent osseointegration are coincident with fracture healing only in the distal aspect of the inserted stem. Absence of proximal osseointegration might lead to poor osseous support resulting in inadequate fatigue strength at the junction of the dual modular revision stem.
