Insight Into

AbstractThe aim of this study was to assess a large, single-surgeon dataset of uncemented total hip arthroplasties that had been templated using software. This assessment compared preoperative templated predictions with what was implanted with regard to (1) femoral prosthesis size and (2) acetabular cup size. The operation notes for two types of uncemented total hip arthroplasty performed by a single surgeon between January 9, 2008, and March 21, 2019, were assessed. The data were refined so that only those that were fully templated on a correctly calibrated pelvic radiograph were included. This provided a total of 153 cases. The predicted software template was compared with actual implanted component sizes. With regard to the femoral stems, the templating software was exactly correct in 45.75% of cases and was accurate to within one size in 87.59% of cases. With regard to the acetabular component, the templating software was exactly correct in 52.94% of cases and was accurate to within one size (2 mm) in 86.94% of cases. Templating software offers an accurate prediction of the size of uncemented femoral and acetabular components. In addition, the benefits of templating include cognitive rehearsal, insight into potentially challenging aspects of surgery, and highlighting intraoperative issues where there is a large intraoperative deviation from what is templated. This study demonstrates the congruence and reproducibility of templating software when compared with other smaller studies performed in the literature.

Musculoskeletal Manifestations

Children affected by mucopolysaccharidosis (MPS) type IH (Hurler Syndrome), an autosomal recessive metabolic disorder, are known to experience a range of musculoskeletal manifestations including spinal abnormalities, hand abnormalities, generalised joint stiffness, genu valgum, and hip dysplasia and avascular necrosis. Enzyme therapy, in the form of bone marrow transplantation, significantly increases life expectancy but does not prevent the development of the associated musculoskeletal disorders. We present the case of a 23-year-old woman with a diagnosis of Hurler syndrome with a satisfactory result following uncemented total hip arthroplasty.

Advanced Stages

<p class="abstract"><strong>Background:</strong> Osteonecrosis of femoral head (ONFH) is characterised by cell death in the subchondral bone caused by abnormalities of blood flow to the femoral head. About 5% to 13% of arthroplasties are performed yearly for ONFH in United States. Ficat and Arlet classification is the commonest system used for grading of ONFH. Advanced stages 3 and 4 are best managed with total hip arthroplasty (THA). THA restores hip range of movement and allows early ambulation in ONFH.</p><p class="abstract"><strong>Methods:</strong> After seeking approval from local institutional ethical committee 25 patients with stage 3 and stage 4 ONFH (Ficat and Arlet) were admitted from OPD of SKIMS MC and Hospital Bemina, Srinagar. The study was conducted from February 2018 to February 2020 in department of Orthopaedics SKIMS MC and Hospital Bemina, Srinagar.  25 patients with mean age of 50.64 years comprising of 13 females and 12 males with unilateral osteonecrosis of femoral head with collapsed head underwent uncemented total hip arthroplasty and were followed up to a minimum of 1 year post-operatively.<strong></strong></p><p class="abstract"><strong>Results:</strong> Outcome was evaluated by comparing pre-operative and post-operative Harris hip scores. The average Harris hip scores improved from 65.87 in the pre-operative group to 96.54 at 1-year follow-up post-operatively. Marked improvement was noted in pain scores. No revisions were performed during the study. One patient developed superficial surgical site infection which healed with supervised dressings and oral antibiotics.</p><p class="abstract"><strong>Conclusions:</strong> Uncemented THA has excellent short-term outcomes in advanced stages of ONFH. It provides mobile hip joint and pain free ambulation shortly after surgery.</p>
