Arthroscopic-Assisted Percutaneous Fixation of a Femoral Head Fracture (Pipkin II): A Case Report.

CASE: Fractures of the femoral head are infrequent injuries with potentially devastating complications. Pipkin type II fractures often require surgical fixation. It involves intraarticular approaches that may increase the inherent morbidity of these fractures. Hip arthroscopy minimizes surgical aggression and allows for direct control of fracture reduction. We present a case report of an arthroscopic-assisted percutaneous fixation of a Pipkin-II femoral head fracture. A hip arthroscopy without traction and percutaneous screw fixation was conducted under arthroscopic and fluoroscopic guidance. CONCLUSION: Arthroscopic-assisted percutaneous fixation is a useful technique for optimal femoral head fracture treatment and may also minimize surgical morbidity and optimize early recovery.

Tillaux fracture in adults - Case report and review of literature.

Avulsion fractures of the distal tibia resulting from anterior inferior tibiofibular ligament are known as Tillaux fractures. This injury is usually seen among adolescents as a Salter Harris type 3 epiphysiolisis in relation to bone weakness in distal tibia due to ephiphyseal closure. Regarding adult patients, this pattern of fracture become such an atypical one due to supposed failure of ligament previous to bone, avoiding avulsion. However, some cases have been described in recent decades.The purpose of the present study is to present an adult Tillaux case and add an exhaustive review of literature regarding mechanism of injury, associated lesions, treatment, postoperative care and follow up. LEVEL OF EVIDENCE: Level V.

Impact of 3-Monthly Vitamin D Supplementation Plus Exercise on Survival after Surgery for Osteoporotic Hip Fracture in Adult Patients over 50 Years: A Pragmatic Randomized, Partially Blinded, Controlled Trial.

OBJECTIVE: To determine whether 3-monthly supplementation of an oral vitamin D widely used in Spain (calcifediol) plus daily exercise could influence survival at one and four years after surgery for osteoporotic hip fracture. DESIGN: A pragmatic, randomized, partially single-blind placebo-controlled study. SETTING: Patients admitted to a tertiary university hospital for acute hip fracture. PARTICIPANTS: 675 healthy adult patients undergoing surgery for osteoporotic hip fracture were recruited from January 2004 to December 2007. INTERVENTION: Patients were randomized to receive either 3-monthly oral doses of 3 mg calcifediol (Hidroferol Choque®) or placebo in the 12 months postsurgery. Patients who received calcifediol were also given an exercise programme. The placebo group received standard health recommendations only. MEASUREMENTS: The primary endpoint was survival at 1 year and at 4 year follow-up. We also recorded new fractures, medical complications and anti-osteoporotic treatment compliance. RESULTS: We included a total of 88 patients, aged 62 to 99 years. Mean age was 82 years and 88.6% were women. At 12 months, 10 (11.3%) patients had died, 9 of them, from the non-intervention group. At 4 years after surgery, 20 (22.7%) had died, 3 (3.4%) from the intervention group and 17 (19.3%) from the non-intervention group. At this time, survival curve analysis showed 93% survival in the intervention group and 62% in the non-intervention group (p=0.001). At 12-month follow up, there were 18 new fractures, 9 in each group. The non-intervention group had more medical complications, with significant differences at visit 2 (p = 0.04) and 3 (p = 0.02) but not at visit 4 (p = 0.18). No significant differences between groups were found regarding treatment compliance. CONCLUSION: 3-monthly, oral supplements of 3 mg calcifediol plus daily exercise improved survival at one-year and four-year follow up after surgery for an osteoporotic hip fracture.

Antiresorptive treatment, when initiated after a first hip fracture, may not protect of a second contralateral episode in elderly population: A study with 685 patients.

INTRODUCTION: Osteoporosis predisposes for a higher risk of hip fracture and its treatment is frequently underprescribed. Our purpose was to assess the relation between having a second hip fracture and receiving osteoporosis treatment. Also to assess the relation between this second fracture and using central nervous system drugs or being institutionalised. PATIENTS AND METHODS: We reviewed all the patients that were admitted to our hospital with an osteoporotic proximal femoral fracture between September 2009 and February 2011. We identified 685 patients, 74 of which presented a contralateral fracture. We evaluated if they were receiving osteoporosis treatment or taking any medication that could affect the central nervous system and if they were institutionalised. RESULTS: A 10.8% of patients had a second fracture and the mean time between the two of them was 20 months (1-122). There was a clear female predominance (76.35%). The mean age at occurrence of the primary fracture was 83.02 years and 85 for the second. A 90.8% did not follow any type of osteoporosis medication before the first fracture. A 50.9% did not receive central nervous system drugs and 79.1% lived at home at the time of the first fracture. 12.8% of the patients that did not follow the osteoporosis treatment, had a contralateral fracture, 3% more than those that did follow some kind of treatment, but this difference was not significant (p=0.2). DISCUSSION: We identified a similar number of patients undergoing osteoporotic treatment as registered in literature. There was no significant difference between suffering a second hip fracture and following osteoporosis treatment, using psychotropic drugs or being institutionalised.

Value of Hodkinson's test for detecting dementia and mild cognitive impairment in epidemiological surveys.

In order to test the value of Hodkinson's test (HT) for the detection of dementia and other milder forms of cognitive impairment in community surveys, we have studied two separate groups of 50 individuals; one of the groups included individuals with dementia or mild cognitive impairment (MCI), and the other individuals with no cognitive disturbances. Both groups were drawn from the same rural population and subjected to HT and a neuropsychological exam for positive and differential diagnosis of cognitive impairment. The gold standard criteria for the diagnosis of dementia and MCI were the DSM-IIIR criteria and a simplified and adapted version of the criteria established for age-associated memory impairment. We found that the best cutoff of HT providing maximum sensitivity and specificity for the diagnosis of both dementia and MCI was 7. For this cutoff, sensitivity and specificity for the diagnosis of MCI were 94 and 90%, respectively; for the diagnosis of dementia sensitivity and specificity were 100 and 53%, respectively. This together with its brevity, low cost and independence of sensory impairment and cultural background makes the HT useful for large population-based screening of dementia and MCI.

Prevalence of age-associated memory impairment and dementia in a rural community.

To obtain accurate estimates of the prevalence of age-associated memory impairment, dementia, and Alzheimer's disease, a population study was carried out in Turégano, a rural community of 1011 inhabitants in the Segovia province of Spain. The study was divided into two phases: a door to door survey of the entire population aged 40 years and over (503 persons), followed by a clinical examination of suspected cases for positive and differential diagnosis of dementia and cognitive impairment. The prevalence of age-associated memory impairment was 3.6% in individuals of 40 years and over and 7.1% in individuals of 65 years and over, whereas dementia was found in 2.6% and 5.2%, respectively. The prevalence rates of both clinical conditions increased with age. The most prevalent clinical category of dementia was dementia of Alzheimer type, which represented 1.8% and 3.8% of these two age groups. The corresponding figures for vascular dementia were 0.4% and 0.9% and for secondary dementia 0.4% and 0.5%. Age-associated memory impairment is an age-dependent disorder with a high prevalence among the elderly; some of these patients may represent an early stage of Alzheimer's disease, suggesting that the prevalence of this disorder may be higher than previously estimated.

[Study of a disease outbreak in a home for the aged]. / Estudio de un brote epidémico en una residencia de ancianos.

OBJECTIVE: To describe an epidemic outbreak in an elderly persons' home. DESIGN: A descriptive, longitudinal study. SETTING: Elderly persons' home in the Riaza Health District, Segovia. PATIENTS AND PARTICIPANTS: 90 elderly people resident at this geriatric centre. MEASUREMENTS AND MAIN RESULTS: Between January 18 and 25, 1995, there was an epidemic outbreak. Some cases had digestive symptoms: diarrhoea and vomiting, but without a temperature. Other cases had respiratory symptoms with temperature, cough, expectoration, breathing difficulty and myalgia. 25 elderly people were affected: 68% suffering the respiratory symptoms; and 32%, the digestive ones. Three people were admitted to hospital and one died. The presence of Rotavirus was found in the faeces of patients with digestive symptoms. The study-period had the highest incidence of flu in this Health District. 20% of the elderly people were not vaccinated for flu. CONCLUSIONS: Elderly persons' homes are an environment which favours the spread of germs which can cause epidemic situations.

[Variability of HIV-1 viral load in patients cared along 4 years]. / Variabilidad de la carga vírica de VIH-1 en individuos atendidos a lo largo de 4 años.

BASIS: Analysis of the variations of HIV-1 viral load (VL) in a cohort of patients. MATERIAL AND METHODS: A retrospective study was designed for the calculation and analysis of the differences between two consecutive measurements of VL in a cohort of 1,336 patients along a 48 months follow-up. RESULTS: At the beginning of the follow-up period the highest proportion of patients with decreases of VL (54.2% in their first measurement, at 0-75 days) as well as the least proportion of patients both without changes (30.7%) and with increases of their VL (15.1%), were registered. The proportion of patients with decreases was declining along the study period. More than half of the patients did not experience significant variations in the measurements carried out. CONCLUSIONS: The significant decreases of VL appeared in our series at the beginning of the follow-up period, and a growing proportion of individuals showed elevations of the VL along the period studied.
