15-year survivorship of a unique dual-modular femoral stem in primary hip arthroplasty
BackgroundHip offset, version, and length are interdependent femoral variables which determine stability and leg length. Balancing these competing...

The impact of retaining the femoral stem in revision total hip arthroplasty: a systematic review, meta-analysis, and meta-regression
IntroductionThe management of well-fixed femoral stems in revision total hip arthroplasty (rTHA) remains a subject of debate, with concerns over...

Shape-memory sawtooth-arm embracing clamp used in complex femoral revision hip arthroplasty for stem stability: average 9-year follow-up study
BackgroundNickel-Titanium shape-memory sawtooth-arm embracing clamps (SSECs) have been used in revision total hip arthroplasties (rTHAs) to protect...

Cementless curved endoprosthesis stem for distal femoral reconstruction in a Chinese population: a combined anatomical & biomechanical study
BackgroundThe endoprosthetic knee reconstruction using a current universal femoral stem might not be suitable for local population due to the...

Locking plate for periprosthetic femoral fractures according to Vancouver C: Outcome and radiological subanalysis of 40 patients
PurposePeriprosthetic femoral fractures (PFF) according to type Vancouver C are less common and outcome is limited reported. Therefore, we conducted...

Mid-term results of total hip arthroplasty with anatomical ultra-short cementless stem in patients with developmental dysplasia of the hip Crowe type II
The aim of this study was to present the mid-term results of ultra-short cementless stem total hip arthroplasty (THA) in patients with Crowe type II...
-
Safe range of femoral neck system insertion and the risk of perforation
BackgroundInternal fixation of the femoral neck carries a risk of perforation due to the presence of the isthmus of the femoral neck. At present,...

Extra Medullary Fixation in Unstable Proximal Femoral Fractures by PF-LCP
PurposePerception that extra-medullary fixation of these fractures are fraught with difficulties and deficiencies is becoming inappropriate. This...

Mid-term results of a new femoral prosthesis using Ti-Nb-Sn alloy with low Young’s modulus
BackgroundThis study was performed to investigate the mid-term results of Ti-Nb-Sn (TNS) alloy stem with a low Young’s modulus.
Methods ...

Long-term survivorship of an exchangeable-neck hip prosthesis with a Ti-alloy/Ti-alloy neck–stem junction
IntroductionBreakage of exchangeable-neck (EN) and adverse local tissue reactions (ALTRs) to neck–stem junction (NSJ) damage products are responsible...

Removal of an osteointegrated broken uncemented femoral stem after hip arthroplasty—technical note
Broken stems are particularly challenging in revision hip arthroplasty, as no standard extraction instruments fit anymore. Well-integrated uncemented...

Risk of complications and implant survival of surgical treatment of proximal femoral metastasis: a meta-analysis
PurposeThe patients with femoral metastasis in the inter- or subtrochanteric area could be treated with intramedullary nailing or prosthetic...
-
Comparison of single taper and dual taper versions of the same stem design in total hip arthroplasty for primary osteoarthritis
BackgroundIn total hip arthroplasty (THA), the outcomes of single taper (ST) and dual taper (DT) versions of the same stem design have been scarcely...
-
Outcomes of conversion total hip arthroplasty for failed fixation of intertrochanteric fractures with monoblock distal-loading reconstruction stem
PurposeThe aim of our study was to analyze the clinical and radiological outcomes of conversion total hip arthroplasty (THA) for failed fixation of...

Favorable revision-free survivorship of cemented arthroplasty following failed proximal femoral nail antirotation: a case series with a median follow-up of 10 years
BackgroundGiven the ever-increasing rate of failure related to proximal femoral nail antirotation (PFNA), it is expected that an increasing number of...
