Relatively low and moderate pre-fracture serum 25-hydroxyvitamin D levels associated with the highest survival in elderly hip fracture patients in Finland: a minimum 3-year follow-up.

The association between serum 25-hydroxyvitamin D level and post-fracture mortality indicates beneficial relatively high serum 25-hydroxyvitamin D concentrations. A 1-year cohort study on 245 hip fracture patients in Finland indicated the lowest 3-year mortality and highest survival among patients with serum 25-hydroxyvitamin D level of 50-74 nmol/L. PURPOSE: To explore pre-fracture serum 25-hydroxyvitamin D level as a factor associated with post-fracture survival among a cohort of hip fracture patients in Finland. METHODS: A prospectively collected cohort of hip fracture patients (n = 245, 70% women) from two hospitals was followed for 3.2 post-hip fracture years. Serum 25-hydroxyvitamin D was measured in admission to the hospital and classified: < 50, 50-74, 75-99, and ≥ 100 nmol/L. Survival was analyzed with a Bayesian multivariate model. Relative survival was explored with the life table method according to serum 25-hydroxyvitamin D. Mortality according to serum 25-hydroxyvitamin D level and to the hospital was calculated. RESULTS: Mortality in the patients with serum 25-hydroxyvitamin D level of 50-74 nmol/L was significantly lower than in all other patients together at every post-fracture year. The most important factors for survival were age under 85 years; living in an actual/private home; serum 25-hydroxyvitamin D level of 50-74 nmol/L, followed by 75-99 nmol/L; ASA classes 1-2 and 3; and female sex. The mean age of patients with serum 25-hydroxyvitamin D level of 50-99 nmol/L was significantly higher than in other levels. Relative survival was highest in men, women, and patients in hospital B with serum 25-hydroxyvitamin D level of 50-74 nmol. CONCLUSION: The highest 3-year survival and the lowest mortality in this cohort appeared in patients with pre-fracture serum 25-hydroxyvitamin D level of 50-74 nmol/L. This result differs from similar studies and is lower than the recommended level of 25-hydroxyvitamin D among hip fracture patients. The results should be examined in future research with larger data.

Use of benzodiazepines, z-hypnotics and antidepressants among hip fracture patients in Finland. Consistency between recorded and detected benzodiazepines.

PURPOSE: We described the use of benzodiazepines (BZDs), z-hypnotics, and antidepressants; analyzed the consistency between recorded and detected BZDs among hip fracture patients admitted to two Finnish hospitals during one year; and compared the results with corresponding results from 12 years earlier. METHODS: Current use of medication was obtained from the National Prescription Register. Urine and blood samples used to detect BZD were taken during admission. The following Anatomical Therapeutic Chemical (ATC) classes were included: BZDs: N05BA, N05CD; z-hypnotics: N05CF; and antidepressants: N06A.The presence of BZDs in urine was analyzed using immunoassay. Positive BZDs were confirmed by gas chromatography mass spectrometry. BZDs in serum were analyzed using liquid chromatography. Concordance between recorded and detected BZDs was calculated with kappa (κ) and described using a Venn diagram. RESULTS: A total of 245 patients were enrolled in the study. BZD was detected in 18 %. Kappa was 0.39 (95 % CI 0.25-0.53). Overlap of detected and recorded BZDs was 59 %. According to the prescription register, 18 % used z-hypnotics, and according to both the detection of BZDs and register, 49 % used BZDs and/or z-hypnotics. 22 % used antidepressants and 15 % used combinations of the studied drugs concomitantly. CONCLUSION: Use rate of BZDs and/or z-hypnotics was similar to that 12 years ago. No difference in the consistency between our previous and present study was found either. All studied drugs and their concomitant use increase the risk for fractures. In the elderly, point prevalence of medication and appropriateness should be regularly assessed.

A 10-Year Retrospective Study of 490 Hip Fracture Patients: Reoperations, Direct Medical Costs, and Survival.

BACKGROUND AND AIMS: Reoperations after operative treatment of hip fracture patients may be associated with higher costs and inferior survival. We examined the acute hospital costs, long-term reoperation rates, and survival of patients with a new hip fracture. MATERIALS AND METHODS: A total of 490 consecutive new hip fracture patients treated at a single center between 31 December 2004 and 6 December 2006 were analyzed retrospectively. Fractures were classified according to Garden and AO. All medical records were checked manually. The costs of reoperations were calculated using the diagnosis-related groups (DRG)-based prices. Survival analysis was performed using the life-table method. The follow-up time was 10 years. RESULTS: In all, 70/490 patients (14.3%) needed reoperations. Of all reoperations, 34.2% were performed during the first month and 72.9% within 1 year after the primary operation. The hemiarthroplasty dislocation rate was 8.5%, and mechanical failures of osteosynthesis occurred in 6.2%. Alcohol abuse was associated with a heightened risk of reoperation. The mean direct costs of primary fracture care were lower than the mean costs of reoperations (€7500 vs €9800). The mortality rate at 10 years was 79.8% among non-reoperated patients and 62.9% among reoperated patients. CONCLUSIONS: According to our hypothesis, the cost per patient of reoperation in acute care was 31% higher than the corresponding cost of a primary operation. Reoperations increased the overall immediate costs of index fractures by nearly 20%. One-third of all reoperations were performed during the first month and almost 75% within 1 year after the primary operation.

Remarkable improvement in serum 25-hydroxyvitamin levels among hip fracture patients over a 12-year period: a prospective study in South-eastern Finland.

Hypovitaminosis D is a problem among hip fracture patients. In a 1-year cohort study comprising 245 hip fracture patients (mean age of females 81 years and males 78 years) from south-eastern Finland, the mean 25-hydroxyvitamin D [S-25(OH)D] concentration was 73(SD 31) nmol/L. Vitamin D supplementation has been integrated into our current practice. INTRODUCTION: The objectives of this study are to verify vitamin D levels among hip fracture patients and to compare the results with a similar study conducted in the same two hospitals covering the same geographic area 12 years ago. METHODS: A prospective cohort comprising 245 Caucasian hip fracture patients was enrolled in the study in two acute hospitals in south-eastern Finland (61° N) over a 12-month period in 2015-2016. The S-25(OH)D was measured using 25-hydroxyvitamin D electrochemiluminescence binding assay. The S-25(OH)D concentrations were compared with the corresponding concentrations of a similar cohort analyzed in the same two hospitals 12 years ago. RESULTS: Of the 245 patients, 70% were women with a mean age of 81 (SD 10) years, while the men had a mean age of 78 (SD 12) years (p < 0.01). The total mean S-25(OH)D concentration was 73 (SD 31.3) nmol/L. Regional differences were found: 15% in hospital A and 36% in hospital B had a S-25(OH(D level < 50 nmol/L, and the mean S-25(OH)D level was 79.2 (SD 31.7) nmol/L in hospital A and 62.4 (SD 27.5) nmol/L in hospital B (p < 0.001). No differences were found in S-25(OH)D concentrations by either the place of residence or the time of year. Overall, the percentage of patients with a sufficient vitamin D level (> 50 nmol/L) was remarkably higher in 2015-2016 (77%) than in 2003-2004 (22%). CONCLUSION: Our results indicate that vitamin D supplementation has been widely integrated into our current practice. However, regional differences were found in the S-25(OH)D concentrations for which the reasons are unknown.

An 8-year follow-up study of 221 consecutive hip fracture patients in Finland: analysis of reoperations and their direct medical costs.

BACKGROUND: Some hip fracture patients need one or more reoperations because of complications following initial operative treatment. AIMS: The aim of this study was to identify all further surgical interventions in a cohort of patients with hip fractures over a period of 8 years after index fracture. Immediate direct costs of these reoperations were also calculated. MATERIAL AND METHODS: This retrospective study investigated 221 consecutive patients with hip fractures operated on at two different hospitals in southeastern Finland. The study period in hospital A was from 1 February 2003 to 31 January 2004, and in hospital B from 1 February 2003 to 30 April 2004. About 50% were femoral neck fractures, 41% trochanteric fractures, and 9% subtrochanteric fractures. Patients' medical records were checked from the hospital records and confirmed manually. Short- and long-term complications were recorded. Survival analysis was performed using a life-table method. The actual costs for reoperations and other further procedures for each patient were calculated using diagnosis-related groups-based costs for both hospitals in 2012. RESULTS: A total of 20 patients (9%) needed reoperations. Overall, 10 patients (8.9%) with a femoral neck fracture (n = 112), 8 patients (8.7%) with trochanteric fracture (n = 92), and 2 patients (10.5%) with subtrochanteric fracture (n = 19) were reoperated on. The median interval between the primary operation of the acute hip fracture (n = 20) and the first reoperation was about 300 days (range: 2 weeks to 82 months). Among the women reoperated on, the excess mortality was lower than among those undergoing a single operation. The median costs of treatment per patient with one or more reoperations were €13,422 in hospital A (range: €1616-€61,755), €11,076 in hospital B (range: €1540-€17,866), and €12,850 in the total study group (p = 0.43). In the case of infections (3 patients), the mean costs per patient were €28,751 (range: €11,076-€61,755). CONCLUSIONS: Almost 10% of hip fracture patients required reoperations, and these reoperations caused significant direct costs to health care. However, direct costs account for only approximately 25% of the first year's total costs. These costs should be taken into account when evaluating the economics of hip fractures and the burden of health care.

Acute alcohol use among patients with acute hip fractures: a descriptive incidence study in southeastern Finland.

AIM: To assess the very recent use of alcohol among patients admitted to two Finnish hospitals due to an acute hip fracture. METHOD: Very recent use of alcohol was recorded according to the patient's or the relatives' report. Ethanol was measured in blood samples taken at admission. Serum gamma-glutamyltransferase, aspartate aminotransferase and alanine aminotransferase, and vitamin D concentration were measured. Reported use of medication, vitamin D, and/or calcium supplementation was recorded. RESULTS: Complete data were obtained on 222 of 375 eligible patients; 71% of those enrolled were women. The mean age of women was 80.5 years (SD 10) and of men 73 years (SD 12) (P < 0.001). The fracture type was femoral neck in 50%, trochanteric in 41%, and subtrochanteric in 9%. The use of alcohol within 24 h before the accident leading to hip fracture was reported by 21.5% of men and 7% of women; positive serum alcohol levels were noted in 17% (19% of men and 16% of women) and 2.2% had a level of >1.0 mg/l. Recent alcohol use was more common among patients in the age group of 65-74 years than among older patients (P < 0.001). The use of alcohol was associated strongly with tobacco use (P = 0.00012) but had no association with vitamin D levels. Alcohol users used less medication than non-users (P < 0.01). Women seemed to conceal their use of alcohol more than men (P < 0.005). CONCLUSIONS: Alcohol consumption was common among patients with an acute hip fracture, being more common in younger than in older patients. Use of alcohol in the 24 h prior to the injury was reported by 21.5% of men and 7% of women. Alcohol concentration in blood was positive in 19% of men and 16% of women.

Drainage is of no use in primary uncomplicated cemented hip and knee arthroplasty for osteoarthritis: a prospective randomized study.

In a prospective, randomized study, 58 patients with primary cemented hip arthroplasty and 39 patients with primary cemented knee arthroplasty were divided into groups with postoperative closed-suction drainage and without drainage. There was no difference in healing of the wounds, postoperative blood transfusions, complications, or range of motion. Although there was more soaked dressing requiring reinforcements in the groups without drainage, as a result of this study, we no longer use drains in uncomplicated cemented primary hip and knee arthroplasties for osteoarthritis.

MR imaging in suspected acute trauma of wrist bones.

OBJECTIVE: The purpose of this study was to evaluate the findings of MR imaging compared to plain radiography in acute wrist trauma. METHODS: Radiography and MR imaging (obtained at 1.5 T) of 67 patients (38 female, 29 male, aged 15-80 years) were analysed by three senior radiologists in a blinded random fashion. RESULTS: One-third (n= 13) of the 37 fractures observed on MR images were missed on the radiographs. The McNemar test indicated significant differences in diagnoses between radiography and MR. CONCLUSION: We recommend that MR imaging should be considered in the diagnosis of acute wrist trauma when: 1) There is a clear discrepancy between the clinical status and a negative radiography and when splint treatment would increase cost by causing occupational restrictions; and 2) Healing of trauma diagnosed as contusion or distension does not occur within the expected time.

Epidemiology and traumatology of injuries in elite soccer: a prospective study in Finland.

A prospective study of male soccer injuries among 12 teams playing at the highest competition level was carried out in Finland in 1993. Overall, two out of three players were injured during the whole season. The injury incidence per 1000 playing hours among injured players and all players during games was higher than during practice, 14.2 vs. 11.3 and 2.3 vs. 1.8, respectively. The lower extremity was involved in 76% of the injuries. Thigh injuries were most frequent (22%), whereas overuse injuries were scarce (6%). Eighteen per cent of the injured players needed surgery and in most cases (58%) the reason for surgery was a knee injury. Sixteen per cent of all injured players were absent from soccer for more than 1 month after the injury. The mean absence time was 17 days for all and 84 days for operatively treated players.

Intravenous cefuroxime prophylaxis. Tissue levels after one 3-gram dose in 40 cases of hip fracture.

This study consists of 2 series of patients with cervical hip fracture treated with hemiarthroplasty. In a preliminary study, the method, timing of sample collection, and tissue and serum concentrations were studied in 15 patients. In the main study of another 25 patients, only tissue samples were collected. In the preliminary study, 3 g of cefuroxime was infused in 15-25 min and serum, muscle, fascia and bone samples were collected at various times. In the main study, 1 dose of 3 g of cefuroxime was infused in 15 min. Skin, muscle, fascia, and bone tissue samples were collected after 30 and 45 min and the concentrations of cefuroxime were measured by high-performance liquid chromatography. In the preliminary study, serum cefuroxime levels were 61 micrograms/mL and 42 micrograms/mL at 15-30 and 35-50 min, respectively. Cefuroxime levels in various tissues were only slightly less than those in serum. Blood contamination contributed less than 30 percent to the tissue levels of cefuroxime. In the main study, mean cefuroxime levels in the tissues were in the range of 39-58 micrograms/g, and the total range was 5.5-151 micrograms/g at 30 and 45 min. These concentrations are well above the MIC values of the most common bacteria causing wound and bone infections.

Modified distal metatarsal osteotomy for hallux valgus.

Sixty-three feet in 44 patients with a hallux valgus, which had been operated on using a modified distal osteotomy were reviewed after a mean follow-up of 4.6 years. A modification of Mitchell's and Mommsen's osteotomies was used without any fixation material. The mean correction of the intermetatarsal angle was 2.6 degrees and of the hallux valgus angle 5.2 degrees. Good subjective result was achieved in 90% of the feet. In six (9.5%) cases the hallux valgus angle was worse after the operation. The method used seems to be too unreliable to be continued. Patient selection was found to be of great importance. Hallux valgus angle of more than 40 degrees was less suitable for this kind of operation.

One dose cefuroxime prophylaxis in hip fracture surgery.

One 3 g intravenous dose of cefuroxime during the induction of anaesthesia was administered randomly in a series of 162 consecutive hip fractures. The overall infection rate was 8.0%, and 2.4% for deep infections. The number of infections was seven in the prophylaxis group and six in the control group. The percentage of deep infections was 3.9 and 1.4, correspondingly. Antibiotic prophylaxis given did not seem to have an effect on the infection rate.

Tc-99m HMPAO labeled leukocytes superior to bone scan in the detection of osteomyelitis in children.

Seven children (aged 7 to 16 years) with confirmed osteomyelitis underwent imaging with Tc-99m HMPAO labeled leukocytes and with Tc-99m diphosphonates. The patients were scanned at 1/2 hour and at 3 hours. The scans were evaluated visually, and the lesion-to-normal bone ratios were quantitated. All the lesions on leukocyte scans and six out of seven lesions in bone scans were readily detectable 1/2 hour after injection of the radiopharmaceutical, but 3 hours is the better imaging time. In quantitative analysis, the lesion-to-normal bone ratio increased with leukocytes significantly higher than with the bone scans (P less than 0.05). When the scintigraphic findings were compared with surgical and radiologic results, the leukocyte images detected and localized lesions better than the bone scans. According to these preliminary results, Tc-99m HMPAO labeled leukocytes seem to offer a rapid and accurate method for detecting bone infections.

Lumbar disc herniation in the elderly: a rare and rewarding object for surgery.

We carried out a four to twelve year follow-up study in thirteen patients aged 63 years and over who were operated on for lumbar disc herniation. In eleven cases the herniation was at the L 4-5 level and in two at the L 5--S 1 level. Additional bony entrapment was present in eight cases. Simple disc removal through a small laminotomy was performed in eight patients, with a good or excellent result in four cases. Disc removal through a hemilaminectomy or laminectomy with the necessary lateral decompression of the bony entrapment gave a good or excellent result in each of the five patients. It is concluded that disc operation in the elderly usually gives acceptable late results. When even a minor bony stenosis is present at the disc herniation level, hemilaminectomy or even laminectomy should be considered.

Alvik's glenoplasty for humeroscapular dislocation. 6-year follow-up of 52 shoulders.

In Alvik's modification of the Eden-Hybbinette operation, an iliac crest bone graft is inserted in a groove in the glenoid rim of the scapula. In this retrospective study, 52 shoulders in 46 patients operated on using the modified Alvik's method were reviewed. The mean age of the patients at the time of the operation was 32 years, and the average follow-up time was 6 years. There were no operative complications, and two thirds of the patients were satisfied with the operation. Spontaneous redislocation occurred postoperatively in only one shoulder. In addition, there were 10 traumatic redislocations. Postoperative arthrosis was found in nine shoulders; the arthrosis had more correlation with the patient's age at the time of the operation than with the follow-up time. In 41 shoulders, there was bony healing of the transplant.

External fixation of Colles' fracture.

Radiographic and functional results of external fixation of 32 Colles' fractures were compared with the results of plaster fixation of 189 Colles' fractures. Despite the fact that the fractures treated with the external device were more unstable and comminuted, the final results were equal in both groups, and the radiographic outcome of external fixation was superior. Pin loosening decreased with predrilling rather than self-tapping. We recommend external fixation for unstable fractures of the distal forearm.
