Introduction

Cementless tapered wedge stems have shown excellent results over the last decade. Distal potting with inadequate proximal fit, as well as failure to achieve biologic fixation has led to thigh pain, loosening and implant failure. To support a variety of patient morphologies a novel tapered wedge stem was designed with reduced distal morphology, maximizing the proximal contact of the grit blasted surface. The objective of the study was to analyze the clinical outcomes of this stem design.

Methods

Three hundred and nineteen patients enrolled into prospective, post-market multicenter studies received a novel tapered wedge stem. Clinical and patient-reported outcomes including the Harris Hip Score (HHS), Lower Extremity Activity Scale (LEAS), Short Form 12 (SF12), and Euroqol 5D Score (EQ-5D) were evaluated preoperative through two years postoperative.

We present here a case of pseudotumor formation likely due to metal wear debris generated at the head-neck taper (trunnion) of the femoral stem and head components in a metal-on-highly cross-linked polyethylene (MOP) total hip arthroplasty. Over the last few years, this recently described diagnosis, trunnionosis, is being recognized and reported more frequently. This patient presented with a rather large (12 cm diameter) pseudotumor with accompanying loss of abductors and a pelvic discontinuity making reconstruction more challenging. We believe the psuedotumor in this patient developed from trunnionosis. This is an interesting case of aseptic lymphocyte-dominated vasculitis-associated lesions (ALVAL) in a MOP total hip arthroplasty.

This study describes percutaneous method of tennis elbow release and medium term results.

Materials and Methods: Eighteen patients (20 elbows) were reviewed following percutaneous tennis elbow release. All patients in this series underwent non-operative management with limited or no relief prior to surgery. The mean duration of treatment was 34.04 months prior to surgery. A percutaneous release of common extensor origin was performed under local anaesthetic. A small 1 cm skin incision was employed in all cases. Mean follow- up was 73 months with a range of 8–121 months. All patients except returned to work and normal level of activity. There was one poor result. The mean time to return to work was 5 weeks, with a range of 1 day –12 weeks. Thirteen patients (fifteen elbows) have been clinically examined. Five patients were contacted by phone.

Results: Pain after surgery was evaluated with a visual analogue scale. Eighteen elbows (90% of cases) had an excellent result. Pain was rated at zero in seventeen cases. One case rated at zero at rest and two after heavy activity. One elbow (5%) had a good result with pain at zero at rest and raising four on the visual analogue scale after sporting activities (playing tennis for more than one hour). There was no improvement in one case (5%) with a visual analogue score of eight before and after surgery. There were no complications recorded. These results prove that percutaneous elbow release is a viable option in treatment of failed conservative tennis elbow management though astringent selection criteria should be observed.
