Aims

Despite advances in the treatment of paediatric hip disease, adolescent and young adult patients can develop early onset end-stage osteoarthritis. The aims of this study were to address the indications and medium-term outcomes for total hip arthroplasty (THA) with ceramic bearings for teenage patients.

Aims

The aim of this study was to assess orthopaedic oncologic patient morbidity resulting from COVID-19 related institutional delays and surgical shutdowns during the first wave of the pandemic in New York, USA.

The high prevalence of osteoarthritis (OA), as well as the current lack of disease-modifying drugs for OA, has provided a rationale for regenerative medicine as a possible treatment modality for OA treatment. In this editorial, the current status of regenerative medicine in OA including stem cells, exosomes, and genes is summarized along with the author’s perspectives. Despite a tremendous interest, so far there is very little evidence proving the efficacy of this modality for clinical application. As symptomatic relief is not sufficient to justify the high cost associated with regenerative medicine, definitive structural improvement that would last for years or decades and obviate or delay the need for joint arthroplasty is essential for regenerative medicine to retain a place among OA treatment methods.

Aims

The aim of this study was to measure the effect of hospital case volume on the survival of revision total knee arthroplasty (RTKA).

Aims

The main aims were to identify risk factors predictive of a radiolucent line (RLL) around the acetabular component with an interface bioactive bone cement (IBBC) technique in the first year after THA, and evaluate whether these risk factors influence the development of RLLs at five and ten years after THA.

The imminent introduction of the new Trauma & Orthopaedic (T&O) curriculum, and the implementation of the Improving Surgical Training initiative, reflect yet another paradigm shift in the recent history of trauma and orthopaedic training. The move to outcome-based training without time constraints is a radical departure from the traditional time-based structure and represents an exciting new training frontier. This paper summarizes the history of T&O training reform, explains the rationale for change, and reflects on lessons learnt from the past.

Aims

Ultrasound (US)-guided injections are widely used in patients with conditions of the shoulder in order to improve their accuracy. However, the clinical efficacy of US-guided injections compared with blind injections remains controversial. The aim of this study was to compare the accuracy and efficacy of US-guided compared with blind corticosteroid injections into the glenohumeral joint in patients with primary frozen shoulder (FS).

Aims

This study aimed to identify the tibial component and femoral component coronal angles (TCCAs and FCCAs), which concomitantly are associated with the best outcomes and survivorship in a cohort of fixed-bearing, cemented, medial unicompartmental knee arthroplasties (UKAs). We also investigated the potential two-way interactions between the TCCA and FCCA.

Aims

We aimed to address the question on whether there is a place for shoulder stabilization surgery in patients who had voluntary posterior instability starting in childhood and adolescence, and later becoming involuntary and uncontrollable.

Aims

The purpose of this study was to determine whether there were long-term differences in outcomes of reverse shoulder arthroplasty (RSA) undertaken for acute proximal humeral fracture versus rotator cuff deficiency with a minimum follow-up of five years.

1. By questionnaire, an attempt has been made to ascertain the characteristics of a hundred cases of slipping of the upper femoral epiphysis. 2. The principal object has been to see whether an etiological classification would be possible pending an assessment of the results of treatment. 3. Proper statistical analysis has proved impossible because of the incompleteness of the data. 4. As usual, boys predominated and were usually affected as much as three years older than the girls. 5. It was exceptional to find epiphysial slipping in a girl once she had begun to menstruate. 6. Nearly a quarter of the cases were bilateral, or became so after six to twenty-four months or more. 7. Little information came from an enquiry about dietary fads, the estimation of urinary ketosteroid excretion in twenty-three of the patients, or some minor pathological investigations. 8. No convincing evidence was found of skeletal retardation or of general thickening of epiphysial discs, such as might perhaps be expected in a hormonal disturbance characterised by defective epiphysial maturation. 9. From each child with the necessary data, indices of height, weight and build were ascertained, which would indicate his expectation of finding a place among a hundred physically normal children of his own sex and age, and, if so, where that place would be. From these studies four groups of children seemed to emerge: I) what may be called abnormally heavy children who would not find a place among a hundred, or somestimes a thousand, physically "normal" children of their own age and sex; 2) unusually heavy children who would find a place in the heaviest minority of the normal hundred; 3) a very small group of abnormally small people, among whom might be expected the subjects of pituitary infantilism; and 4) a large group of children of average physique for their sex and age. 10. From this information and from clinical evidence in the case returns, it appeared that a quarter of the assessable boys and nearly two-thirds of the assessable girls showed evidence of endocrine defect, quite apart from those who were merely unusually fat. 11. By distinguishing these two groups of children from a third group of constitutionally "normal," an attempt has been made to see whether there is any correlation between evident endocrine defect and such characteristics as bilateral affection, delayed epiphysial maturation, a history of relevant injury and its nature, and sudden or gradual epiphysial slipping. 12. No relationship was established between any of these characteristics and endocrine type: bilateral affection was no commoner in the endocrine group; delayed maturation was not demonstrated in either; a history of relevant injury was equally common, and its nature identical, in both; slipping might be sudden or gradual in either indiscriminately. 13. There was a history of seemingly relevant injury in half the patients, and it was much commoner with sudden slipping than with gradual slipping. Sudden slipping was often preceded by symptoms of gradual slipping, or sudden slipping of one epiphysis was sometimes followed by gradual slipping of the other. 14. In gradual slipping the cardinal symptoms were pain and limp, usually starting synchronously and gradually; the pain was usually intermittent and referred much more often to the hip than the knee; the limp was usually continuous. 15. Of signs, demonstrable wasting seemed to be absent as often as present, but shortening was usual. Lateral rotation deformity was usually present, adduction often, and flexion sometimes. In more than a third of the cases limitation of movement was slight enough to be easily missed. 16. The radiographic observations confirmed the seeming widening at the affected epiphysial disc, the greater displacement revealed by the lateral view, and the difficulty of identifying avascular necrosis before collapse. 17. Treatment was delayed in thirty-four cases—a third of the whole; the reasons have been analysed; diagnostic failure was the cause in nineteen. 18. A few cases outside the series have been mentioned briefly because of special points of interest: slipping in gross pituitary disease—in pituitary giantism, and(at the age of thirty-three) in pituitary hypogonadism; slipping with defect of the opposite lower limb—infantile paralysis of the leg, and Legg-Calvé-Perthes disease of the hip; familial affection—slipping in two brothers. 19. The results of treatment in the present cases, supplemented by others, have been studied by Dr John Hall and related to some of the clinical features. His paper appears separately

Aims

A proximal femur fracture (PFF) is a common orthopaedic presentation, with an incidence of over 25,000 cases reported in the Australian and New Zealand Hip Fracture Registry (ANZHFR) in 2018. Hip fractures are known to have high mortality. The purpose of this study was to determine the utility of the Clinical Frailty Scale (CFS) in predicting 30-day and one-year mortality after a PFF in older patients.

Aims

The purpose of this study was to determine the impact of the removal of total knee arthroplasty (TKA) from the Medicare Inpatient Only (IPO) list on our Bundled Payments for Care Improvement (BPCI) Initiative in 2018.

Aims

The purpose of this study was to evaluate the incidence and analyze the trends of surgeon-reported complications following surgery for adolescent idiopathic scoliosis (AIS) over a 13-year period from the Scoliosis Research Society (SRS) Morbidity and Mortality database.

Informed consent is a very important part of surgical treatment. In this paper, we report a number of legal judgements in spinal surgery where there was no criticism of the surgical procedure itself. The fault that was identified was a failure to inform the patient of alternatives to, and material risks of, surgery, or overemphasizing the benefits of surgery. In one case, there was a promise that a specific surgeon was to perform the operation, which did not ensue. All of the faults in these cases were faults purely of the consenting process. In many cases, the surgeon claimed to have explained certain risks to the patient but was unable to provide proof of doing so. We propose a checklist that, if followed, would ensure that the surgeon would take their patients through the relevant matters but also, crucially, would act as strong evidence in any future court proceedings that the appropriate discussions had taken place. Although this article focuses on spinal surgery, the principles and messages are applicable to the whole of orthopaedic surgery.
