“…The patients in this study should comparable improvement in their hip scores compared to previous reports of patients who underwent complex, primary, cementless, total hip arthroplasty with conical prostheses as well as modular prostheses [1,2,6,8,11,15,19,27,28,30,31]. Despite predictable success with similar stems, it remains critically important to systematically report clinical and radiographic results whenever new technology is introduced.…”

“…The optimal stem design in these patients is unknown. A number of studies have reported that modular prostheses such as the S-ROM (DePuy, Inc) can help deal with these anatomical challenges [2,5,6,11,19,30]; however, a theoretical disadvantage includes the potential for metal corrosion with modularity [9,20]. The Wagner Cone stem can accommodate small or deformed femora because of its proximal conical, tapered design.…”

Background Total hip arthroplasty (THA) in patients with small or abnormal proximal femoral anatomy is challenging as a result of complex anatomic deformities in the hip. It is unclear which stem is the most appropriate for these patients. One possible implant design that may help meet this need is the modified Wagner Cone prosthesis, whose design consists of monoblock cone with splines; however, to our knowledge, no clinical results have been published using this implant. Questions/purposes We evaluated the hip scores and radiographic results (including signs of osseointegration and subsidence) of complex primary THA using the modified Wagner Cone cementless femoral component in patients with small or abnormal proximal femoral anatomic proportions.

“…No study involving retrieval analysis or metal ion levels was included. Twenty reports on dual modular femoral components in the literature met inclusion criteria [4,6,8,12,17,19,20,24,35,40,44,48,68,71,73,75,[78][79][80][81].

“…This increased frequency of revision with exchangeable neck prostheses occurred with all bearing surfaces in the Australian Registry (Table 3). Twelve studies reported on various types of modular femoral neck and stem components with a range of survivorship from 91% to 100% with a range of followup of 8.6 and 5 years, respectively [4,8,17,19,20,35,44,68,73,[79][80][81]. Eight reports dealing specifically with the S-ROM modular stem/body (DePuy Orthopaedics Inc, Warsaw, IN, USA) reported a range of survivorships for aseptic loosening of 93.3% to 100% with a range of followup of 19 years and 10 years, respectively [6,12,24,40,48,71,75,78].…”

Background Total hip arthroplasty (THA) continues to be one of the most successful surgical procedures in the medical field. However, over the last two decades, the use of modularity and alternative bearings in THA has become routine. Given the known problems associated with hardon-hard bearing couples, including taper failures with more modular stem designs, local and systemic effects from metal-on-metal bearings, and fractures with ceramic-onceramic bearings, it is not known whether in aggregate the survivorship of these implants is better or worse than the metal-on-polyethylene bearings that they sought to replace. Questions/purposes Have alternative bearings (metal-onmetal and ceramic-on-ceramic) and implant modularity decreased revision rates of primary THAs?Methods In this systematic review of MEDLINE and EMBASE, we used several Boolean search strings for each topic and surveyed national registry data from Englishspeaking countries. Clinical research (Level IV or higher) with C 5 years of followup was included; retrieval studies and case reports were excluded. We included registry data at C 7 years followup. A total of 32 studies (and five registry reports) on metal-on-metal, 19 studies (and five registry reports) on ceramic-on-ceramic, and 20 studies (and one registry report) on modular stem designs met inclusion criteria and were evaluated in detail. Insufficient data were available on metal-on-ceramic and ceramic-onmetal implants, and monoblock acetabular designs were evaluated in another recent systematic review so these were not evaluated here.One of the authors (WMM) receives royalty payments, during the study period, an amount of USD 10,000 to USD 100,000 from B Braun/Aesculap Inc (Center Valley, PA, USA) and less than USD 10,000 from Elsevier Inc (Philadelphia, PA, USA); receives USD 10,000 to USD 100,000 as a consultant for B Braun/Aesculap Inc and less than USD 10,000 from Medtronic Inc (Memphis, TN, USA); receives research funding, during the study period, an amount of less than USD 10,000 from B Braun/Aesculap Inc and less than USD 10,000 Stryker Inc (Mahwah, NJ, USA); and serves on the editorial boards for the Journal of Arthroplasty, The Knee, the International Journal of Orthopaedics, and The Journal of Long Term Effects of Medical Implants.

Purpose Modular necks used in total hip replacement (THR) have become an increasingly discussed topic with the recent recall of multiple modular systems, but it is anticipated that outcomes for these devices are highly design-specific. The objectives of this study were to determine if the survivorship and complication rates of a specific modular femoral stem (PROFEMUR® Z, MicroPort Orthopedics Inc., Arlington, TN, USA) were significantly lower than those of all cementless fixed neck stems in an arthroplasty registry. Methods The database of an arthroplasty registry was searched for all patients implanted with a specific modular stem and all those implanted with cementless fixed neck stems. Kaplan-Meier survivorship and complication rates were compared between the two groups. Results The 12-year survivorship of the modular stem (95.8 %) was not significantly less than that of all cementless fixed neck stems (96.1 %). There was also no difference in revision rates for dislocation, periprosthetic fractures, aseptic loosening or septic loosening between the two groups. Conclusions The use of the specific modular stem did not adversely affect long-term component survivorship or complication rates when compared to all cementless fixed neck THRs in an arthroplasty registry.
