Total hip arthroplasty (THA) is often required to decrease the excessive anatomical femoral anteversion (AA) in developmental dysplasia of the hip. Studies have recommended decreasing the AA via the use of a retroverted modular neck. However, hip rotation after THA may strengthen or weaken the effect of changing the AA. Thus, the present study anal...
The aim of this study is to conduct a systematic review of clinical outcomes and complications of modular neck THA among Italian cohorts. Only reviewed publications focused on Italian cohort patients in English language were considered for inclusion. Studies were included if they involved patients who underwent total hip replacement surgery with mo...

Neck-stem modularity gained recent popularity in hip arthroplasty for clinical advantages, and few complications have been reported. We describe an unusual two-stage failure of the bimodular neck of a cementless forged titanium alloy stem implanted 12 years before. The retrieved neck was forwarded to the manufacturer for metallurgic evaluation and ...

PurposeThe objective was to assess aseptic complications and functional outcome using a primary total hip arthroplasty with modular neck.MethodsProspective cohort of 317 consecutive patients. The mean age was 61.1 (range, 41–84) years. The H-Max-M model (Lima, Italy) system was used in all patients. The functional assessment was made by the Harris ...
Purpose The aim of this study is a radiographic evaluation and to determine serologic values of chromium and cobalt in the blood and urine of patients who have been implanted with a Stryker® ABG II Modular Neck and see if there is correlation with the features of prosthesis and patients.MethodsThe study involves the collection of data from patients...

The mid-term results of this new polished stem were excellent, without adverse effects from the use of modularity.

In recent decades, the popularity of modular necks in total hip arthroplasty (THA) has increased since modular necks offer the potential to restore the patient's native anatomy, and thus improve stability. Unfortunately, modular necks are associated with higher complication rates, including implant fracture and modular junction corrosion with adver...
Modular neck hip prosthesis born in the 1990 with the aim of allowing the surgeon to modify CCD angle, offset and femoral anteversion intra-operatively restoring patient’s original biomechanics. In order to achieve the best biomechanics of the reconstructed hip, preoperative planning is essential. In the last few years modularity has been questione...

The management of the patient with a recalled, modular neck-body total hip arthroplasty can be complex, as it involves a combination of clinical, technical, and medicolegal challenges. Management begins with a thorough history and physical exam, radiographic evaluation, infection workup, and serum metal ion levels. Three-dimensional imaging is obta...
Since November 2004 we have been using a modular short-stem hip prosthesis with a less invasive anterolateral approach in 154 cases. The modified Watson-Jones  approach allows the insertion of the hip prosthesis without detaching muscles. The modularity of the prosthesis offers the choice of different degrees of anteversion and CCD angles to res...
