The aim was to clarify the associations among subjective symptoms, clinical signs of temporomandibular disorders (TMD), and radiographic findings in the mandibular condyles of elderly people during a 5-year follow-up.
As part of a comprehensive medical survey of a random sample born in 1904, 1909, and 1914 (Helsinki Aging Study), 364 subjects living in Helsinki participated in the dental part of the examination during 1990 and 1991; after 5 years, 103 of these were reexamined. Comprehensive data on TMD were available for 94 subjects, and radiographic data were available for 88. TMD were assessed by Helkimo's anamnestic and clinical indices, and radiographic status was assessed by panoramic radiographs.
During the 5-year follow-up, reported anamnestic symptoms of TMD for men changed little (9%); among women, the change from baseline was 42%. When the unchanged indices were compared, the gender difference was obvious. At baseline, 5% of the women, but no men, had severe signs (clinical index III) of TMD. At the end of follow-up, none showed severe signs. Comparison of radiographic findings between baseline and follow-up showed no differences, nor did differences appear in associations between radiographic findings and anamnestic or clinical indices.
During the 5-year follow-up, signs and symptoms of TMD in these elderly individuals became milder or vanished. The radiographic status of the condyles remained stable, and no association appeared between radiographic findings and signs and symptoms of TMD.
The properties and performance of a new low-monomer cement were examined in this prospective randomized, controlled RSA study. 5-year data have already been published, showing no statistically significant differences compared to controls. In the present paper we present the 10-year results.
44 patients were originally randomized to receive total hip replacement with a Lubinus SPII titanium-aluminum-vanadium stem cemented either with the new Cemex Rx bone cement or with control bone cement, Palacos R. Patients were examined using RSA, Harris hip score, and conventional radiographs.
At 10 years, 33 hips could be evaluated clinically and 30 hips could be evaluated with RSA (16 Cemex and 14 Palacos). 9 patients had died and 4 patients were too old or infirm to be investigated. Except for 1 hip that was revised for infection after less than 5 years, no further hips were revised before the 10-year follow-up. There were no statistically significant clinical differences between the groups. The Cemex cement had magnitudes of migration similar to or sometimes lower than those of Palacos cement. In both groups, most hips showed extensive radiolucent lines, probably due to the use of titanium alloy stems.
At 10 years, the Cemex bone cement tested performed just as well as the control (Palacos bone cement).
In this prospective multicentre cohort study we studied subjects younger than 60 years of age scheduled for primary total hip arthroplasty (THA). The study assessed patients' overall satisfaction, fulfillment of preoperative expectations, the effect on socioeconomic parameters, and quality of sex-life. Questionnaires including Oxford Hip Score (OHS) and SF-36 were evaluated preoperatively and 3, 6 and 12 months postoperatively. OHS and SF-36 showed significant improvements (p
There are numerous reports and evidences to suggest that exercise therapy is effective for knee osteoarthritis (knee OA). However, there is a lack of sufficient research concerning the factors influencing its application and effectiveness. The purposes of this study were to evaluate effects of the mode of treatment delivery on the improvement of symptoms in knee OA, and to analyze potential risk factors affecting improvement after exercise therapies.
The 209 women applicants diagnosed with knee OA were randomly allocated into either a group performing group exercise in a class or a group performing home exercise. The 90 min exercise program was performed under the guidance of physiotherapists as a group exercise therapy. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) of the subjects of both groups before and after intervention was compared to examine the effect of exercise therapy. In addition, body mass index, knee range of motion (ROM), the femorotibial angle from radiographs, OA severity from Kellgren-Lawrence grade, and meniscus abnormality and subchondral bone marrow lesions from MRI findings were statistically analyzed as factors that may affect exercise therapy.
A significantly greater improvement in WOMAC was observed in the subjects of group exercise (81 subjects) as compared with the subjects of home exercise (122 subjects). There was a significantly high proportion of subjects with knee flexion contracture among the subjects participating in group exercise that showed only minor symptom improvement (p
The study was performed to investigate the relationship between perceived muscle tension and electromyographic hyperactivity and to what extent electromyographic (EMG) hyperactivity relates to personality traits in fibromyalgics. Thirty-six females with fibromyalgia performed isokinetic maximal forward flexions of the shoulder combined with surface EMG recordings of the trapezius and infraspinatus muscles. Signal amplitude ratio and peak torque were calculated in the initial and endurance test phases. Pain intensity, perceived general and local shoulder muscle tension, and personality traits using the Karolinska Scales of Personality were assessed pre-test. Neither perceived muscle tension nor muscular tension personality trait correlated with EMG muscle hyperactivity. Perceived general muscle tension correlated with aspects of anxiety proneness (including muscle tension) of the Karolinska Scales of Personality. Pain intensity interacted with many of the variables. We propose that when patients with fibromyalgia report muscle tension that they may be expressing something other than physiological muscle tension.
Hip arthroscopy is being performed with expanding indications, commonly including symptomatic labral tears. The effects of various patient factors, including patient age, on clinical outcomes are not well understood. The purpose of the present study was to quantify the postoperative functional and quality-of-life outcomes after arthroscopic debridement of symptomatic labral tears in patients forty-five years of age or older.
Forty-one patients who were at least forty-five years of age (mean age, 52.7 years [range, 45.5 to 67.0 years]; mean body mass index, 26.1 kg/m² [range, 18.4 to 33.2 kg/m²]; 75.6% female) and who underwent labral debridement at the time of hip arthroscopy were included. Disease-specific clinical outcome measures (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] and modified Harris hip score [mHHS]) and general health-related measures (12-Item Short Form Health Survey [SF-12]) were collected preoperatively and postoperatively.
The reoperation rate was 17% (seven of forty-one) at a mean of 21.3 months, and six of the seven reoperations involved conversion to hip arthroplasty or resurfacing. The overall hip arthroscopy cohort had postoperative improvements in the mean WOMAC pain score (from 54.0 [range, 20 to 90] to 69.4 [range, 0 to 100], p

There is no consensus on the association between global femoral offset (FO) and outcome after total hip arthroplasty (THA). We assessed the association between FO and patients' reported hip function, quality of life, and abductor muscle strength.
We included 250 patients with unilateral hip osteoarthritis who underwent a THA. Before the operation, the patient's reported hip function was evaluated with the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index and quality of life was evaluated with EQ-5D. At 1-year follow-up, the same scores and also hip abductor muscle strength were measured. 222 patients were available for follow-up. These patients were divided into 3 groups according to the postoperative global FO of the operated hip compared to the contralateral hip, as measured on plain radiographs: the decreased FO group (more than 5 mm reduction), the restored FO group (within 5 mm restoration), and the increased FO group (more than 5 mm increment).
The long-term effect of distal radial fracture malunion on activity limitations is unknown. Between 2001 and 2002, we conducted a prospective cohort study of all patients with distal radial fracture treated with casting or percutaneous fixation in northeast Scania in Sweden. In that original study, the patients completed the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire at baseline and at 2 years. We performed a long-term follow-up study of patients who were 18 to 65 years of age at the time of the fracture to investigate the association between fracture malunion and activity limitations.
In this long-term follow-up, patients who had participated in the original study completed the DASH questionnaire and a visual analog scale (VAS) for pain and for satisfaction (scored, 0 [best] to 100) and underwent radiographic and physical examinations at 12 to 14 years after the fracture. We defined malunion as dorsal angulation of =10°, ulnar variance of =3 mm, and/or radial inclination of =15°. We also assessed the presence of radiocarpal osteoarthritis and ulnar styloid nonunion. The primary outcome was the change in DASH score from baseline. Secondary outcomes were DASH, pain, and satisfaction scores, wrist range of motion, and grip strength at the time of the follow-up.
Of 85 eligible patients, 63 (74%) responded to the questionnaires and underwent examinations. Malunion was found in 25 patients, osteoarthritis was found in 38 patients, and styloid nonunion was found in 9 patients. Compared with patients without malunion, those with malunion had significantly worse DASH scores from baseline to 12 to 14 years (p = 0.002); the adjusted mean difference was 11 points (95% confidence interval [CI], 4 to 17 points). Similarly, follow-up scores were significantly worse among patients with malunion; the adjusted mean difference was 14 points (95% CI, 7 to 22 points; p 0.05) with DASH scores, VAS pain or satisfaction scores, or grip strength.
Patients who sustain a distal radial fracture at the age of 18 to 65 years and develop malunion are more likely to have worse long-term outcomes including activity limitations and pain.

The purpose of this study was to evaluate if there is an association between the side of unilateral shoulder pain and the patient's preferred sleeping position and if the preferred sleeping position is related to which side of a double bed one lies in.
In a cross-sectional study, adult patients seeking chiropractic care with unilateral shoulder pain were asked about sleeping position and, if sleeping with a partner, which side of the bed they slept in. A total of 83 participants were included from 10 chiropractic clinics. Associations were cross-tabulated and tested by Fisher exact test.
The pain was in the right shoulder in 55% (95 % confidence interval, 46-66) of the participants with unilateral pain. The side of shoulder pain was associated to the side patients slept on, with 67% of those sleeping on one side lying on the painful shoulder (P = .02). Moreover, patients were more likely to turn away from their partner at night, and 76% slept on the side opposite their partner (P
Several studies have reported lower neck muscle strength in patients with chronic neck pain compared to healthy controls. The aim of the present study was to evaluate the association between the severity of neck pain and disability with neck strength and range of movement in women suffering from chronic neck pain. One hundred and seventy-nine female office workers with chronic neck pain were selected to the study. The outcome was assessed by the self-rating questionnaires on neck pain (visual analogue scale, Vernon's disability index, Neck pain and disability index) and by measures of the passive range of movement (ROM) and maximal isometric neck muscle strength. No statistically significant correlation was found between perceived neck pain and the disability indices and the maximal isometric neck strength and ROM measures. However, the pain values reported during the strength tests were inversely correlated with the results of strength tests (r=-0.24 to -0.46), showing that pain was associated with decreased force production. About two-thirds of the patients felt pain during test efforts. Pain may prevent full effort during strength tests and hence the production of maximal force. Thus in patients with chronic neck pain the results do not always describe true maximal strength, but rather the patients' ability to bear strain, which may be considerably influenced by their painful condition. The results of the present study suggest that rehabilitation in cases of chronic neck pain should aim at raising tolerance to mechanical strain.
