SummaryAseptic loosening of the femoral implant (ALFI) has been reported in 7.2% of total hip arthroplasty procedures in the dog. In this case report, ALFI was diagnosed in a nine year old male German Shepherd, seven years after the initial cemented total hip arthroplasty was performed. The revision of the ALFI was performed using a longitudinal osteotomy to extract the polymethylmethacrylate and the titanium femoral prosthesis was replaced with a cobalt chromium model. The osteotomy and an iatrogenic femoral fracture were repaired using four 1.3 mm cables. Postoperative radiographs revealed satisfactory alignment, reduction of the osteotomy and adequate positioning of the femoral prosthesis.Case report describing the revision of aseptic loosening of the femoral implant seven years after the initial total hip arthroplasty was performed.

Limb Length Inequality

Obtaining soft tissue balance and correct tension across a total hip arthroplasty can be challenging. This is particularly so following revision of a proximally deficient femur. Although stability of the hip arthroplasty is the paramount concern, limb length inequality is a consideration that is of importance to both surgeon and patient. We describe a novel adaptation in instrumentation to help the surgeon faced with these problems when using cemented Exeter components.

Abstract Purpose Head-neck modularity was introduced into total hip arthroplasty to provide more intraoperative surgical options. However, modularity led to new problems, such as trunnionosis and fractures of the femoral prosthesis neck. The purpose of this study was to identify risk factors for hip neck fractures and to provide recommendations to prevent damage and fractures of the neck. Methods A systematic review of the literature was performed according to the PRISMA guidelines. Results Thirty-three case studies were included. Methodologically, most included studies were of moderate or good quality. The 80 neck fractures included in the review took place, on average, 7 years after stem placement. Male gender, high body weight, obesity, previous revision surgery, mixing components from different manufacturers, use of long skirted heads, cobalt-chromium (large size) heads were identified as potential risk factors. Conclusion Hip neck fractures occur on average 7 years after stem placement. The etiology of hip neck fractures is multifactorial. This review revealed several preventable implant- and surgeon-related risk factors.

Abstract Background Trunnion fracture of the femoral prosthesis is an extremely rare complication following Total Hip Arthroplasty (THA). There are very few reports in literature on trunnion fracture. All previously reported cases are of prostheses with smaller heads, unlike the large metal-on-metal articulation in our case, which is unique. Case presentation A 29-year-old male patient with juvenile idiopathic arthropathy presented to us with a fracture of the trunnion of his left THA, with no history of trauma. He had undergone staged bilateral THA for avascular necrosis of the hips 10 years ago (with AML-A stem and large metal-on-metal articulation bilaterally). We revised the THA and exchanged both femoral and acetabular components. He had a good functional outcome at 3 years’ follow up. Conclusion The primary reason for the trunnion fracture in our case was the faulty stem design of the AML [with a small (9/10) taper, and a large head], causing excessive bending moment at the trunnion, worsening the cantilever effect and leading to subsequent cyclic fatigue failure. Whilst gross trunnion failure (GTF) with dissociation of the head from the taper is commonly reported, trunnion fracture per se is a rare and devastating complication. The AML-A stem has since been recalled by the company and there is a need to constantly monitor these patients for potential trunnion-related complications.
