Hip fractures in centenarians: a multicentre review of outcomes.

INTRODUCTION: Advances in healthcare have resulted in an increasing UK population, with the proportion of elderly individuals expanding significantly, including centenarians. Hospitals can expect to see growing numbers of so-called 'super-elderly' patients with trauma, a majority of whom will have hip fractures. We performed a multicentre review of hip fracture outcomes in centenarians to assess whether being an outlier in age correlates with poorer prognosis. METHODS: Centenarians admitted to Basingstoke, Southampton, Dorset, and Salisbury district hospitals with hip fractures between January 2014 and June 2019 were included. Electronic records were searched to obtain demographics, functional status, and admission details. RESULTS: A total of 60 centenarians were included, with a median age of 101 years (range 100-108 years), 85% of whom were female; 29 were admitted from their own home or sheltered housing and 31 from nursing or residential care; 33 had some outdoor mobility, 26 only mobilised indoors, and 1 had no mobility. Common comorbidities were renal and heart disease and dementia. Of the total, 56 underwent surgery, 51 within 36 hours. In terms of accommodation, 63.4% returned to their pre-injury level of independence. At 30 days, three months, and one year, mortality rates were 27% (n = 16), 40% (n = 24) and 55% (n = 33), respectively. CONCLUSION: Trauma in the elderly population is an area of growing interest, yet few studies address centenarians with hip fractures. This work demonstrates that mortality rates within one year of injury were high, but almost half survived beyond a year. Two-thirds of patients regained their pre-injury level of independence, suggesting that functional recovery may not be as poor as previously reported.

A longitudinal study of MARS MRI scanning of soft-tissue lesions around metal-on-metal total hip arthroplasties and disease progression.

We investigated the changes seen on serial metal artefact reduction magnetic resonance imaging scans (MARS-MRI) of metal-on-metal total hip arthroplasties (MoM THAs). In total 155 THAs, in 35 male and 100 female patients (mean age 70.4 years, 42 to 91), underwent at least two MRI scans at a mean interval of 14.6 months (2.6 to 57.1), at a mean of 48.2 months (3.5 to 93.3) after primary hip surgery. Scans were graded using a modification of the Oxford classification. Progression of disease was defined as an increase in grade or a minimum 10% increase in fluid lesion volume at second scan. A total of 16 hips (30%) initially classified as 'normal' developed an abnormality on the second scan. Of those with 'isolated trochanteric fluid' 9 (47%) underwent disease progression, as did 7 (58%) of 'effusions'. A total of 54 (77%) of hips initially classified as showing adverse reactions to metal debris (ARMD) progressed, with higher rates of progression in higher grades. Disease progression was associated with high blood cobalt levels or an irregular pseudocapsule lining at the initial scan. There was no association with changes in functional scores. Adverse reactions to metal debris in MoM THAs may not be as benign as previous reports have suggested. Close radiological follow-up is recommended, particularly in high-risk groups.

Posterior mini-incision total hip arthroplasty controls the extent of post-operative formation of heterotopic ossification.

Heterotopic ossification (HO) is the formation of bone at extra-skeletal sites. Reported rates of HO after hip arthroplasty range from 8 to 90 %; however, it is only severe cases that cause problems clinically, such as joint stiffness. The effects of surgical-related controllable intra-operative risk factors for the formation of HO were investigated. Data examined included gender, age of patient, fat depth, length of operation, incision length, prosthetic fixation method, the use of pulsed lavage and canal brush, and component size and material. All cases were performed by the same surgeon using the posterior approach. A total of 510 cases of hip arthroplasty were included, with an overall rate of HO of 10.2 %. Longer-lasting operations resulted in higher grades of HO (p = 0.047). Incisions >10 cm resulted in more widespread HO formation (p = 0.021). No further correlations were seen between HO formation and fat depth, blood loss, instrumentation, fixation methods or prosthesis material. The mini-incision approach is comparable to the standard approach in the aetiology of HO formation, and whilst the rate of HO may not be controllable, a posterior mini-incision approach can limit its extent.

Sinus involvement in breast cancer: case report.

OBJECTIVE: To report a rare and unique presentation of metastatic breast cancer. METHOD: Case report and review of related literature. RESULTS: A 62-year-old female with metastatic breast cancer, who had been free from recurrence for 4 years, presented with diplopia secondary to lateral rectus palsy. This was due to a sphenoid sinus metastasis, which was eroding into her cavernous sinus, resulting in VIth cranial nerve neuropathy. CONCLUSION: All paranasal sinuses and the orbit are potential sites for metastases. Spread to the paranasal sinuses from breast cancer has been documented previously. However, we believe this to be the only reported case with lateral rectus palsy as a result of metastasis to the sphenoid sinus in which this was the only evidence of disseminated disease. Otolaryngology clinicians need to consider metastatic disease to the sinuses in patients with a history of neoplasia, but also recognise that tamoxifen treatment can itself cause visual disturbance.
