Treatment of large acetabular defects: a surgical technique utilizing impaction grafting into a metallic mesh.

Project description:BackgroundRevision total hip arthroplasty in cases with severe acetabular bone loss is challenging. In the presence of combined cavitary and segmental defects without superior acetabular coverage, reconstructions with a structural acetabular allograft protected by a cage or a custom-made triflange cage have been the treatment of choice. The current paper describes an impaction grafting into a mesh for uncontained defects in revision total hip arthroplasty.Description of techniqueAfter restoring containment with a mesh fixed with small fragment screws, defects were restored using impaction grafting combined with a cemented all-polyethylene cup.Patients and methodsFourteen consecutive acetabular impaction graftings were performed by two surgeons. All patients had a type 3B defect according to the Paprosky classification.ResultsNo re-revisions or radiographic failure was detected in the early follow-up period.ConclusionImpaction grafting into a mesh is an interesting treatment option to restore bone in combined cavitary and segmental defects.

Reconstruction of Proximal Metaphyseal Femoral Defects Using Trabecular Metal Augments in Revision Total Hip Arthroplasty.

Project description:Porous tantalum augments are widely used in revision total hip arthroplasty for the reconstruction of severe bone defects. Here, we present the first 3 cases who underwent femoral revision arthroplasty using standard distal femoral and proximal tibial porous tantalum cones to reconstruct severe bone loss in the proximal femur. Cones were inserted press fit, followed by implantation of a cemented revision stem in all cases. After a mean follow-up period of 15.8 months, all patients showed an improved Harris-Hip-Score and no radiological signs of subsidence or loosening. Porous tantalum cones may be an option in the reconstruction of severe femoral defects in revision total hip arthroplasty. The shape of the tantalum cones should be optimized for the use in the proximal femur.

Three-dimensional technology assisted trabecular metal cup and augments positioning in revision total hip arthroplasty with complex acetabular defects.

Project description:BACKGROUND:Revision total hip arthroplasty (THA) with large acetabular defect remains a challenge. Though trabecular metal (TM) cup and augments have been introduced in defect reconstruction with good result, the accurate positioning of implant is important to avoid complications. Therefore, we aimed to evaluate the usefulness of three-dimensional (3D) simulation and 3D model in assisting implant positioning during complex revision THA. METHODS:Sixteen patients (18 hips) who underwent revision THA with a Paprosky type III acetabular defect were analyzed retrospectively. Placement of acetabular cup and TM augments was simulated with 3D simulation software and 3D model preoperatively. Cup anteversion, abduction angle, and hip center were measured in each case preoperatively and postoperatively. Primary outcome was the percentage of outliers according to Lewinnek safe zone and Harris hip score (HHS). Secondary outcome was the correlation between the 3D planned and the postoperative value. RESULTS:The percentage of outliers was significantly corrected from 77.78% (14/18) preoperatively to 38.88% (7/18) postoperatively (p = 0.04). There was a significant correlation between mean planned cup anteversion and postoperative value (13.39 vs 11.99, r = 0.894; p < 0.001). There was a significant correlation between mean planned abduction and postoperative value (42.67 vs 44.91, r = 0.921, p < 0.001). The number of planned and used augments was the same in all the cases. In 15 cases (83.33%), the size of planned and used TM augments was the same. The HHS was significantly improved at final follow-up (80.94 vs 27.50, p < 0.001). No cases presented dislocation or radiological signs of loosening. CONCLUSION:Preoperative 3D simulation and model were considered the useful method to assist implant positioning in revision THA with complex acetabular defect, with moderate to high accuracy and satisfied clinical outcome.

Decreased migration with locally administered bisphosphonate in cemented cup revisions using impaction bone grafting technique.

Project description:Background and purpose - Impaction bone grafting (IBG) in revision hip surgery is an established method in restoring bone stock deficiencies. We hypothesized that local treatment of the morsellized allograft with a bisphosphonate in cemented revision would, in addition to increased bone density, also reduce the early migration of the cup as measured by radiostereometry (RSA). Patients and methods - 20 patients with aseptic cup loosening underwent revision using the IBG technique. The patients were randomized to either clodronate (10 patients) or saline (10 patients, control group) as local adjunct to the morsellized bone. The outcome was evaluated by dual-energy X-ray absorptiometry (DXA) during the first year regarding periacetabular bone density and with radiostereometric analysis (RSA) for the first 2 years regarding cup migration. Results - 2 patients were lost to follow-up: 9 patients remained in the clodronate and 9 in the control group. Less proximal migration was found in the clodronate group compared with the controls, measured both over time (mixed-models analysis, p = 0.02) as well as at the specified time points up to 2 years (0.22?mm and 0.59?mm respectively, p = 0.02). Both groups seemed to have stabilized at 1 year. We found similar bone mineral density measured by DXA, and similar RSA migration in the other directions. No cups were re-revised. Interpretation - Local treatment of the allograft bone with clodronate reduced early proximal migration of the revised cup but without any measurable difference in periacetabular bone density.

Arthroscopically Assisted Surgical Decompression and Fibular Strut Grafting for Proximal Humerus Avascular Necrosis: Surgical Technique.

Project description:Avascular necrosis is a relatively common entity that affects the proximal humerus and can lead to substantial morbidity. It often occurs in younger patients for whom the traditional treatment of shoulder arthroplasty is not optimal. Fibular strut grafting to prevent humeral head collapse has been described as a viable treatment option. However, it is technically challenging to direct the fibular strut graft into the center of the bony infarct, where it will be most effective. This paper describes a technique of arthroscopically assisted fibular strut grafting for avascular necrosis of the humerus. This is a minimally invasive technique with low morbidity and an accurate way of placing the graft into the infarcted segment.

Induced Membrane Bone Grafting Technique for Treatment of Large Postinfectious Acetabular Bone Defects.

Project description:Management of large acetabular bone defects is challenging. The Masquelet technique has successfully reconstructed segmental defects in long bones arising from trauma, tumors, or infection but not been described for large acetabular defects. We present 3 cases of large acetabular bone defects arising from chronic prosthetic joint infection, treated via a novel induced membrane bone grafting technique, drawn from the Masquelet technique. All cases showed satisfactory clinical and radiological outcomes at midterm follow-up. This technique holds promise and can be an alternative means when treating large acetabular bone defects.

Impaction Bone Grafting for Treatment of Unstable Osteochondritis Dissecans (OCD) Lesions.

Project description:Although treatment options for unstable and unsalvageable large osteochondral lesions have largely been limited to autologous chondrocyte implantation (ACI) and osteochondral allografts, isolated impaction bone grafting represents a cost-friendly alternative, with predictable outcomes comparable to other options. Furthermore, the procedure can be completed in a single stage on an elective basis. We present our technique for impaction bone grafting of unstable osteochondritis dissecans (OCD) using either cancellous autograft or allograft.

Impaction technique influences implant stability in low-density bone model.

Project description:Aims:Cementless acetabular components rely on press-fit fixation for initial stability. In certain cases, initial stability is more difficult to obtain (such as during revision). No current study evaluates how a surgeon's impaction technique (mallet mass, mallet velocity, and number of strikes) may affect component fixation. This study seeks to answer the following research questions: 1) how does impaction technique affect a) bone strain generation and deterioration (and hence implant stability) and b) seating in different density bones?; and 2) can an impaction technique be recommended to minimize risk of implant loosening while ensuring seating of the acetabular component? Methods:A custom drop tower was used to simulate surgical strikes seating acetabular components into synthetic bone. Strike velocity and drop mass were varied. Synthetic bone strain was measured using strain gauges and stability was assessed via push-out tests. Polar gap was measured using optical trackers. Results:A phenomenon of strain deterioration was identified if an excessive number of strikes was used to seat a component. This effect was most pronounced in low-density bone at high strike velocities. Polar gap was reduced with increasing strike mass and velocity. Conclusion:A high mallet mass with low strike velocity resulted in satisfactory implant stability and polar gap, while minimizing the risk of losing stability due to over-striking. Extreme caution not to over-strike must be exercised when using high velocity strikes in low-density bone for any mallet mass.Cite this article: Bone Joint Res 2020;9(7):386-393.

Early experience with robot-assisted Frey's procedure surgical outcome and technique: Indian perspective.

Project description:PurposeRobotic surgery for pancreatic diseases is currently on the rise, feasible, well-accepted, and safe. Frequently performed procedures in relation to pancreatic diseases include distal pancreatectomy and pancreatoduodenectomy. The literature commonly describes robotic lateral pancreaticojejunostomy; however, data on robot-assisted Frey's is scarce.MethodsWe herein, describe our series and technique of robot-assisted Frey's procedure at our tertiary care center between November 2019 and March 2022, and its short-term outcomes in comparison to the open Frey's. Patients with chronic pancreatitis having intractable pain, dilated duct, and no evidence of inflammatory head mass or malignancy were included in the study for robot-assisted Frey's.ResultsIn our study, out of 32 patients, nine patients underwent robot assisted Frey's procedure. The duration of surgery was significantly longer in robotic group (570 minutes vs. 360 minutes, p = 0.003). The medians of intraoperative blood loss and postoperative analgesic requirement were lower in robotic group, but the difference was not statistically significant (250 mL vs. 350 mL, p = 0.400 and 3 days vs. 4 days, p = 0.200, respectively). The median length of hospital stay was shorter in the robotic group, though not significant (6 days vs. 7 days, p = 0.540). At a median follow-up of 28 months, there was no significant difference in the postoperative complications and short-term outcomes between the two groups.ConclusionRobotic surgery offers benefits of laparoscopic surgery in addition it has better visualization, magnification, dexterity, and ergonomics. Frey's procedure is possible robotically with acceptable outcomes in selected patients.

Favorable survival of acetabular reconstruction with bone impaction grafting in dysplastic hips.

Project description:UNLABELLED: Acetabular bone loss hampers implantation of a total hip arthroplasty in patients with developmental dysplasia of the hip. The bone impaction grafting technique in combination with a cemented total hip can restore the bone stock in these patients, but do these reconstructions yield satisfying long-term results? We used this technique in 28 hips (22 consecutive patients). The degree of dislocation was graded preoperatively as Crowe I in five hips, Crowe II in eight hips, Crowe III in nine hips, and Crowe IV in four hips. We present the long-term results of this bone impaction grafting technique a minimum of 10 years after surgery. Two patients died before the minimum followup of 10 years, leaving 20 patients (26 hips). Two cups were revised, one cup for a sciatic nerve palsy (at 2 years) and the other for aseptic loosening after 12 years. The cumulative survival of the cup with revision for any reason as the end point was 96% at 10 years and 84% at 15 years. There were no femoral revisions during followup. The bone impaction grafting technique in combination with a cemented cup is an effective technique for developmental dysplasia of the hip with favorable long-term results. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.
