Here, we present an interesting case of seroma following hip resurfacing arthroplasty in a 69-year-old man. During the postoperative recovery, the patient made rapid progress and returned to intense activity within the 6-week period. He subsequently developed further right hip pain and swelling. On further examination and on ultrasound scan, a lateral thigh collection was noted. All inflammatory markers were within normal parameters; clinically, there was no evidence of active infection. On initial aspiration and washout, there was a large sterile haemoserous collection. The patient subsequently underwent further aspiration due to persistent collection. After this a revision procedure was performed in two stages with excision of the seroma cavity superficial to fascia lata. Methicillin-sensitive Staphylococcus aureus was grown on extended cultures which was treated successfully with antibiotics. After the second stage revision to total hip replacement, this cavity then recollected. A further trial of aspiration with injection of 200 mg doxycycline, a known sclerosing agent, was performed. The seroma resolved.

Patient Reported

Patient-reported outcome and satisfaction scores have become increasingly important in evaluating successful surgery. This case-matched control study compared patient-reported outcome and satisfaction data following hip resurfacing and total hip arthroplasty. Thirty-three consecutive patients selected for hip resurfacing were compared with 99 patients undergoing cemented total hip replacement (THR), matched for age, sex and pathology. Participants completed a Short-Form 12 Health Survey (SF-12) and Oxford Hip Score questionnaire preoperatively and 6 months post operatively with an additional patient satisfaction questionnaire. There was no difference in length of hospital stay. While both groups reported improved outcome scores, multivariate regression analysis did not demonstrate any significant benefit for one group over the other. Both groups reported high levels of satisfaction, which tended to be better in patients undergoing hip resurfacing.

Joint Prostheses

The UHMWPE acetabular cups are the most popular joints for joint prostheses after Charnley introduced UHMWPE for the acetabular component in 1962. It has been demonstrated that polyethylene wear remains the main source of particles in the THR and therefore requires particular attention. The paper presents a series of theoretical and practical aspects regarding the wear of acetabular cups (made of UHMWPE) from the total hip prosthesis component. At the same time, the other tribological phenomena that occur in these MoP (metal on polyethylene) combinations are treated, such as lubrication and friction. Total Hip Replacement & Hip Resurfacing A hip replacement involves replacing the hip joint with a mechanical bearing system which is comprised of a femoral component and an acetabular component. During a hip replacement the acetabulum is reamed and the acetabular component is fitted into the cavity and the femoral component can either be placed over a reamed femoral head, in a procedure referred to as hip resurfacing, or positioned inside the femoral shaft during a total hip replacement [1].

Zirconia Toughened Alumina

By 2050, 130 million people are estimated to suffer from osteoarthritis worldwide which would require patients to undergo total hip replacement procedure which have a lifespan of 20 years and failure rates of ~1%. In this research, Zirconia Toughened Alumina (ZTA) which is the main biomaterial used for total hip arthroplasty were doped with varying vol % of Tantalum Oxide (Ta2O5) from 0 to 0.4 vol % were produced through conventional two-stage sintering with first stage sintering temperature, ranging between 1400°C and 1550°C, heated at 20°C/min, followed by second stage sintering temperature of 1350°C and hold for 12 hours. The efficacy of two-stage sintering on the microstructure and mechanical properties of the sintered samples were then evaluated. Addition of Ta2O5 combined with two-stage sintering were able to produce ZTA composites with enhanced grain size and mechanical properties compared to undoped ZTA composites. The samples with 0.3 vol% Ta2O5 content and above sintered at T1 ≥1450°C achieved density > 99% T.D., Vickers hardness > 19 GPa, Young’s modulus > 400 GPa and fracture toughness > 6 MPam1/2 when compared to undoped ZTA composites. This would enable production of ZTA with improved mechanical properties and lifespan ensuring the well-being of people suffering from osteoarthritis.

Hip Arthrodesis

Patients with hip arthrodeses are at risk of developing back pain or pain in other joints in the long term. Conversion to a total hip replacement or hip resurfacing leads to resolution of symptoms in most patients. We report a 40-year-old man who underwent conversion of a hip arthrodesis to hip resurfacing with good results.

We present a case of symptomatic trochanteric non-union following total hip replacement treated initially with a Dall-Miles grip plate. After failure of this treatment, the patient had a two-stage revision. Trochanteric non-union is one of the well-described complications after total hip replacement. It is frequently difficult to treat, while potentially causing weakness, altered gait and instability of the artificial joint. We believe that reattachment of the trochanter combined with a staged revision of the femoral stem using a posterior approach for the second stage could be a valuable technique to be added to the orthopaedic armamentarium for recurrent and symptomatic trochanteric non-unions after primary total hip replacement, particularly after failure to treat with all the other techniques described in literature.

Joint Reaction Forces

Resurfacing hip arthroplasty and total hip replacement both aim to restore anatomical parameters. Leg length and offset discrepancy can result in altered joint reaction forces, and are associated with increased wear, dislocation, and decreased patient satisfaction. This study assesses the accuracy of leg length and offset restoration after either a Birmingham Hip Resurfacing (BHR) or a cemented total hip replacement (THR). Standardised antero-posterior radiography was performed on two groups of 30 patients with unilateral primary osteoarthritis undergoing either a cemented total hip or resurfacing. The normal contra-lateral hip was used as the control. Leg length and offset were measured pre-operatively with no significant difference between the two groups. Cup offset, femoral offset, total offset and leg length of the prosthesis and normal side were measured by two observers and mean measurements were analysed by a paired t test. Leg lengths in each group did not differ significantly from the normal side, THR 0.53 mm (95% CI -2.4 to 3.4 mm) but BHR implantation did result in mean leg shortening of -1.9 mm (95% CI -4.5 mm to 0.6 mm). Cup offset differed significantly from normal anatomy in both groups, as did femoral and total offset for the total hip replacement group. However, femoral offset was restored in the Birmingham resurfacing group. When the THR group was compared against the BHR group we found no difference between restoration of leg lengths (p = 0.21) and cup offset (p = 0.30) but femoral (p = 0.0063) and total offset (p = 0.03) were restored more accurately with a BHR.
