Background: Periprosthetic hip infections (PHIs) are troublesome complications of hip arthroplasties. The gold standard procedure for treating chronic PHI is a 2-stage approach. Recently, however, more conservative approaches have been developed to spare the osseointegrated components and avoid sequestra, bone loss, devascularization, and difficult reconstructions. The partial two-stage approach, which leaves the well-fixed component in situ and removes the loosened component, may be an effective strategy. Objective: This paper, a narrative mini-review, analyzed the preliminary results of a partial 2-stage approach to treating chronic hip arthroplasty infections. Methods: Pertinent papers describing the partial 2-stage approach (leaving the well-fixed component in situ and removing the loosened component) were collected and evaluated. Results: Six main case series were selected. A total of 76 patients were included. Many patients were treated with socket removal and stem retention with quite similar surgical techniques. Many cases included highly virulent bacteria, and no pre-operative selection about comorbidities was performed. The first outcomes of this approach were promising, with a rate of infection control ranging from 81.3% to 100% at mid-term follow-up. Conclusion: This approach proved good at mid-term follow-up; however, many concerns still exist. In particular, the indications are imprecise, and the role of biofilm is still unclear. Despite the first good outcomes, the partial 2-stage approach for chronic PHI should be validated by multicenter prospective studies.
Femoral neck fractures are progressively increasing, due to higher survival rates, particularly among the female population. The gamma nail was created to treat intertrochanteric fracture types 31-A1, 31-A2 and 31-A3 and in some cases basicervical fractures of type 31-B2-1. Complications can be classified as intraoperative and postoperative. The intraoperative might be related to the nail's introduction site, lag and distal locking screw positions. Postoperative complications depend mostly on an incorrect surgical technique, which can lead to an inaccurate nail position and consequent implant failure. We rarely observe failures caused by severe bone osteoporosis.
Ceramic-on-ceramic (COC) total hip arthroplasties (THAs) with large heads (>36 mm) were introduced to reduce dislocation rates and restore the hip anatomy as closely as possible to the native one. To date, the literature is scarce and fragmented; a review is desirable to point out the outcomes and the possible specific complications (noise, groin pain, and taperosis). A systematic review about large-diameter COC THAs was conducted according to the PRISMA guidelines. The PubMed and Cochrane databases were searched using the terms “large”, “big”, “head”, “hip”, and “ceramic.” The methodological quality of the papers was assessed using the MINORS (Methodological Index for Nonrandomized Studies) score. Seven papers (level of evidence: 5 case series and 2 case-control studies) met the inclusion criteria. Clinical outcomes were excellent in >90% of the patients. Groin pain was reported in only 1 article (7%). Radiological outcomes were positive. Minimal revision rates (<2%) were reported at short- to mid-term follow-ups. Dislocation rates were usually <1%. No bearing surfaces failed. No case of trunnionitis was reported. Noise occurred in up to 30% of the patients, mostly squeaking. The noise did not influence clinical outcomes or patients’ satisfaction. Noise was inconstantly associated with component positioning, younger age, high articular excursions, and larger sizes. Large-diameter heads in COC THAs (≥40 mm) showed promising clinical and radiological outcomes with minimal revision rates. Noise is a cause of concern and should be carefully evaluated at longer follow-ups and in larger, prospective, and specifically designed case series.
Introduction: Total hip arthroplasty (THA) after proximal femoral fixation is a challenging procedure due to possible hardware-related complications. Case presentation: A 78-year-old female with hip osteoarthritis had a proximal femoral osteotomy fixed using a blade plate in the same femur 41 years ago. A two-step approach was planned. After a challenging hardware removal, an iatrogenic subtrochanteric fracture below the degenerated hip occurred after three months. THA with a tapered long stem was successfully performed with no need for additional osteosynthesis, and good results were seen two years later. Discussion: THAs in subtrochanteric fractures are technically demanding but feasible in selected cases. Hardware removal before THA implantation may carry important risks, and the surgical team should be prepared to perform arthroplasty in case of complications. Conclusion: THA in a subtrochanteric fracture below hip osteoarthritis is a feasible option in selected cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
