Geriatric Orthopaedic Surgery & Rehabilitation

Thoracolumbar spine fractures are common osteoporotic fractures among elderly patients. Several studies suggest that these fractures can be treated successfully with a nonoperative management. The aim of this study is to evaluate the conservative treatment of elderly patients with a vertebral fracture.

This study is a retrospective cohort study, which included all patients with an age of 65 years and older, who were diagnosed with a vertebral fracture and where therefore admitted to the Geriatric Fracture Center over a period of 2 years. Primary outcome was the level of functioning 6 weeks and 3 months after admission.

We included 106 patients with 143 vertebral fractures, of which 61 patients were evaluated after 3 months. In our population, 53% of the patients had a fracture involving both middle and anterior columns. The majority of the patients functioned sufficiently 6 weeks and 3 months after admission. Analysis showed that age <80 years is an independent predictor of a sufficient level of functioning after 6 weeks.

The nonoperative treatment of elderly patients with a vertebral fracture leads to a sufficient level of functioning 6 weeks and 3 months after admission. In our population, only age <80 years is an independent predictor for a sufficient level of functioning 6 weeks after admission. The level of functioning at 6 weeks predicts the level of functioning 3 months after admission. On comparison, the level of functioning after early ambulation is equal to the level of functioning after immobilization. Where immobilization may lead to complications, early ambulation was not associated with new complications or neurological damage. Based on these advantages, the treatment of elderly patients with a fracture involving both middle and anterior columns may be altered from immobilization to mobilization in the future.

Relatively few patients have dual-energy x-ray absorptiometry to quantify the magnitude of bone loss as they age. Recent work correlates mean computed tomography (CT) attenuation in the level I (L1) vertebra with bone mineral density (BMD), making it possible to objectively evaluate the magnitude of bone loss in osteoporosis by this method. The aims of this study were to evaluate the utility of using CT scans in patients with acute thoracic and lumbar spine fractures to diagnose osteoporosis and using CT attenuation to evaluate the association between age and BMD.

We performed a retrospective study of patients with acute fractures of the thoracic or lumbar spine who had also undergone an abdominal (or L1) CT scan and compared mean CT attenuation in L1 against threshold values. We also compared differences in CT attenuation between younger (<65 years) and older (≥65 years) and older patients.

A total of 124 patients were evaluated (74 thoracic and 50 lumbar fractures). Overall, there was a strong correlation between age and bone density as measured by CT attenuation (r = −.76). Among those with thoracic fractures (<65 years), mean CT attenuation was 196.51 HU. Forty-one patients were ≥65 years and had mean CT attenuation of 105.90 HU (P < .001). In patients with lumbar fractures, 27 patients were <65 years and had a mean CT attenuation of 192.26 HU and 23 patients were ≥65 years and had mean CT attenuation of 114.31 HU (P < .001). At the threshold of 110 HU, set for specificity, the magnitude of difference between the age-stratified cohorts was greater in the thoracic spine (P < .0001 vs P = .003).

Using opportunistic CT, we demonstrate the relative frequency of osteoporosis in patients with acute fractures of the thoracic and lumbar spine and confirm that the association increases with age. The CT attenuation may provide a cheap and convenient method to help confirm a clinical diagnosis of osteoporosis in patients with fractures.

The purpose of this study was to use a nationally representative database to determine the differences in 30-day outcomes based on procedure type for management of proximal humerus fractures including complications, readmission, operative time, and length of stay. Further, we sought to determine patient characteristics and perioperative factors associated with poor outcomes.

This was a retrospective study of the National Surgical Quality Improvement Program (NSQIP) database. The NSQIP comprises a clinical database with systematic patient tracking at multiple hospitals across the United States.

A total of 413 patients with proximal humerus fractures managed surgically were included.

Of 413 patients, 330 underwent open reduction and internal fixation (ORIF) and 83 underwent hemiarthroplasty.

The primary end points included major and minor complications, operative time, rate of return to the operating room, and length of stay.

Compared to the hemiarthroplasty cohort, patients in the ORIF cohort were significantly younger (64.2; 17-90 and 69.3; 20-90, respectively, P = .007) and were significantly less likely to be of functionally dependent status (17.5% and 27.7%, P = .036). Compared to the hemiarthroplasty cohort, the ORIF cohort demonstrated fewer postoperative bleeding complications (2.4% and 8.4%, respectively, P = .016) and shorter operative times (115 vs 131 minutes, P = .017). There were no significant differences between the groups with respect to complications, reoperation rates, or length of hospital stay. On multivariable analysis, hemiarthroplasty demonstrated increased risk of postoperative bleeding compared to ORIF (odds ratio = 7.06, confidence interval: 2.06-24.24; P = .002) as well as increased operative time (P = .01).

Patients who undergo hemiarthroplasty for management of proximal humerus fractures are significantly older and often functionally dependent. When compared to ORIF, hemiarthroplasty is associated with longer operative times and greater risk of bleeding complications.

This study aimed to compare the differences in functional recovery between patients undergoing plate and nail fixation in the very early period after surgery.

This study was designed as a controlled clinical trial that included 18 patients who were surgically treated with either dynamic hip screw as plate fixation or proximal femoral nail as nail fixation for stable intertrochanteric fractures. In particular, all patients selected for the study reported walking completely independently without the use of walking aids prior to sustaining their initial fracture. In all, 8 patients (mean age, 73.8 years; range, 65-89 years) were treated with plate fixation (group plate) and 10 patients (mean age, 79.7 years; range, 70-90 years) were treated with nail fixation (group nail). Functional evaluations were assessed every week after surgery using the Japanese Orthopaedic Association (JOA) hip functional scores and active range of motion (ROM) of the hip joint.

The recovery of activities of daily living (ADLs) according to JOA hip functional scores at week 4 after surgery was significantly better in group nail than in group plate (P = .03), whereas active ROM of hip flexion improved significantly in group plate than in group nail at weeks 3 and 4 after surgery (P = .04 and P = .02, respectively).

The results suggested that nail fixation may provide a more rapid recovery of ADLs than that of plate fixation in the very early period after surgery. However, plate fixation may provide better ROM of hip flexion than that of nail fixation.

To determine whether changing the consultant on-call schedule resulted in a reduction in time to theater for patients presenting with a hip fracture.

Guidelines in the United Kingdom state that patients presenting with a neck of femur fracture should ideally be operated on the day of or the day after admission. However, there is a best practice tariff in the United Kingdom persuading trusts to operate on elderly patients with hip fracture within 36 hours of admission. Differing formats of daily trauma operating lists and varying consultant on-call schedules have the potential to affect a trusts ability to successfully meet such demands.

This study retrospectively analyzed whether changing the on-call schedule from a system where the on-call consultant is changed on a daily basis to one which changes weekly resulted in a reduction in time to theater for such patients and an increase in best practice tariffs paid.

With the initial rotation system, the average time to theater for a fractured neck of femur was 44 hours 46 minutes, with 44.7% of patients having a time to surgery of less than 36 hours. Patients in the modified system underwent surgery with an average time to theater of 32 hours 19 minutes. In 71.7% of these patients, time to surgery was less than 36 hours.

This study demonstrates that changing the schedule to permit a consultant to have a 7-day period of trauma on call at a time instead of only 1 day dramatically reduced the time to theater for patients with hip fracture. This significantly reduced the number of these cases done outside 36 hours and increased trust financial reward.

Vitamin D deficiency is common in older adults in Western countries with seasonal winters, when the amount of sunlight is much reduced. There is a paucity of data on the prevalence of vitamin D deficiency in patients with hip fracture in countries such as Singapore where the climate is predominantly tropical.

In this study, our aims were to ascertain the prevalence of vitamin D deficiency and risk factors associated with vitamin D deficiency in hospitalized elderly patients with hip fracture in Singapore.

We prospectively studied 485 patients with hip fracture admitted to the orthopedic department over a 1-year period. Nonfragility fractures and younger patients (patients <60 years and those with high-impact injuries) were excluded. Data on patient demographics, comorbidities, functional status, and serum 25-hydroxyvitamin D₃ levels were collected. Vitamin D deficiency was defined using Holick classification.

Vitamin D levels were available for 412 patients. Vitamin D deficiency was present in 57.5% (n = 237). Prevalence of vitamin D insufficiency was 34.5%, with only 8% of patients having normal vitamin D levels. Univariate analyses showed Malay race and functional factors (being housebound, requiring bathing and dressing assistance) to be associated with vitamin D deficiency. However, only ethnicity and housebound patients were significant in the multivariate model.

Vitamin D deficiency and insufficiency are common in patients with hip fracture in Singapore. Vitamin D deficiency was associated with being housebound and those of Malay ethnicity. Clothing habits resulting in reduced sunlight exposure may increase the risk of vitamin D deficiency.
