“…Nowadays in the relevant domestic and foreign scientific editions there are no sociological reserachs dealing with PPS use in spine surgery. The relevance of the sociological study is caused by the extreme rarity of clinical application of SPP in our country, which is confirmed by single domestic publications [13,14], while there is a significant number of similar foreign publications, indicating the use of such systems in the US, UK and Germany [4][5][6][7][8][9][10][11][12][15][16][17][18][19][20].…”

“…According to the forecast of Gartner Inc. MIS of the 4th generation should have been implemented and MIS of the 5th generation should have appeared by 2016. In Russia among the most popular preoperative planning systems, which by its functionality are beyond the scope of the requirements imposed on the MIS 1st, 2nd and 3rd generation are: TraumaCAD [4][5][6][7], MediCAD (http://www.hectec.de/content/index.php/us), OrthoView [8][9][10], Sectra AB (http://www.sectra.com/medical/osteoporosis/index.html), Surgimap [11,12] IMPAX orthopedic instruments (http://www.agfahealthcare.com). The aim of this study is the identification of the key challenges arising during the implementation of the preoperative planning systems in the practice of spine surgeons.…”

It is established that relevance of the use of computer systems of the preoperative planning in activities of scientific and medical staff was confirmed 62.3% of the respondents. According to the survey 34.4% of respondents do not use any computer planning systems, and 21.3% of respondents could not name any specific system they are using. Problem of the lack of systematic training of specialized professionals working with specialized software products was revealed-62.3% of respondents obtain the information about the specialized software products only in the frames of various kinds of conferences and workshops.

“…Standing radiographs taken in clinic 3 weeks post-operatively were reviewed and analyzed with commercially available templating software (Traumacad®, Brainlab, Munich, DE) to measure cup abduction, anteversion, and leg length discrepancy, a method that has been found to correlate well with CT-based measurements of implant position. [44][45][46] Number of dislocations were con rmed through telephone interviews with the patients one year or more after surgery. During telephone interviews, patients were also asked if the operative hip had experienced any dislocations, secondary surgery or any other complications in order to assess for any treatments that may have been rendered at outside institutions.…”

BACKGROUNDDislocation after primary total hip arthroplasty (THA) has an incidence of 2-3. Approximately 77% of dislocations occur within the first year after surgery. The SuperPATH technique is a minimally invasive approach for THA that preserves soft tissue attachments. The purpose of this study is to describe the dislocation rate at one year after SuperPATH primary THA. METHODSAll elective primary THAs performed by the senior author using the SuperPATH approach. Exclusion criteria were acute femoral neck fracture, revision surgery, or malignancy. There were 214 of 279 eligible patients available for telephone interviews (76.7%). Medical records were reviewed for secondary outcomes including early and late complications, cup positioning, distance ambulated on postoperative day one, discharge destination, and blood transfusions. RESULTSMean age at surgery was 64 ± 10.8 years and mean time to telephone follow up was 773 ± 269.7 days. There were 104 female and 110 male patients. There were zero dislocations reported. Blood transfusions were performed in 3.7% of patients, and 75.7% were discharged to home at an average of 2.3 ± 1.0 days. Cup position averaged 43.6 ± 5.2° abduction and 20.9 ± 6.2° anteversion, with an average leg length discrepancy of 3.6 ± 3.32mm. Complications included three intraoperative calcar fractures, one periprosthetic femur fracture, one early femoral revision, three superficial infections, and one instance of wound necrosis.CONCLUSIONSuperPATH approach is safe for use in primary THA resulting in a low dislocation rate.

“…The technique has been previously validated by comparison to computed tomography (CT) with good intra-and interobserver reliability as well as correlation with CT measurements as the gold standard. 11 The data was processed through a statistical analysis package (Real Statistics Resource Pack) to determine basic normality and distribution. Statistical significance was selected for a p value less than 0.05 and power of 0.80.…”

Line-to-Line Reaming of Highly Porous Acetabular Components Improves Position and Reduces Variability of Component Placement

2017

View full text Add to dashboard Cite

Accurate and precise acetabular component position in total hip arthroplasty remains challenging even for experienced, high-volume surgeons. Some variability may result from the press-fit technique of cementless components and maybe magnified by the use of highly porous cups with high-friction surfaces. The purpose of this study is to investigate the acetabular component positioning of a hemispherical, highly porous cup with line-to-line reaming compared with press-fit techniques. A retrospective cohort study was performed of 110 consecutive primary total hip arthroplasties performed by a single surgeon using a highly porous acetabular component. Half of the patients had the component implanted with a line-to-line reaming technique and the other half were implanted using a 1 mm press-fit technique. Postoperative radiographs were evaluated for component positioning and loosening at a minimum of 1 year postoperatively by two independent surgeons. Records were reviewed for subsequent surgery. There were no differences between the groups with respect to age, sex, body mass index, operative side, or acetabular component size. The press-fit group had an average abduction angle of 49.4 ± 5° and anteversion of 20.6 ± 7°. The line-to-line group had an average abduction angle of 45.02° [standard deviation (SD) 4.58] and anteversion of 25.42° (SD 4.44) and were statistically different from the press-fit group (p < 0.01). There was significantly less variability in the line-to-line group with respect to anteversion (F-test, p < 0.01) compared with the press-fit group. At most recent follow-up, there were no dislocations, revisions for any reason, or radiographic evidence of loosening in either group. Line-to-line reaming for highly porous cups can improve component positioning and reduce variability compared with press-fit techniques with no difference in fixation or other clinical outcome parameters.
