Association of osteoporotic vertebral compression fractures with impaired functional status

PURPOSE To determine if vertebral compression fractures in elderly women were associated with impairments in physical, functional, and psychosocial performance. SUBJECTS AND METHODS Ten white women with confirmed vertebral compression fractures were age- and race-matched with 10 control subjects without fractures in a case-control design. All subjects invited to participate in this study were patients of the Geriatrics Division of the Department of Medicine at Duke University Medical Center. All study participants lived either in the community or in the independent-living sections of local retirement communities in and around Durham, NC. Subjects with fractures (mean age = 81.9 years, SD = 5.9 years) had two or more vertebral compression fractures in their medical records, whereas control subjects (mean age = 79.6 years, SD = 6.5 years) had no history of vertebral fractures. Spinal radiographs of all women confirmed group assignment. Physical, functional, and psychosocial performances were evaluated. Physical performance was assessed by measurements of maximal trunk extension torque and thoracic and lumbar spinal motion in the sagittal plane, functional reach, mobility skills, 10-ft timed walk, and 6-minute walk test. Thoracic and lumbar spinal configurations were also determined. Functional performance was assessed using the Functional Status Index. Psychosocial performance was assessed with the following scales: Hopkins Symptom Checklist 90 Revised, Rosenberg Self-Esteem Scale, West Haven-Yale Pain Inventory, Beck Depression Inventory, and single-item health-belief questions. RESULTS Control subjects were not significantly different from patients with fractures in age, weight, number of current illnesses, number of prescribed medications, number of pain medications, ratings of lumbar spine degenerative disc disease, or lumbar spine facet joint arthritis. Activity levels and exercise participation were similar in both groups. Control subjects had no vertebral fractures, whereas fracture subjects had 4.2 +/- 2.6 fractures (range: 2 to 10). Thoracic kyphosis was increased and lumbar lordosis was reduced in fracture subjects. Fracture subjects had reduced maximal trunk extension torque, thoracic and lumbar spine sagittal plane motion, functional reach, mobility skills, and 6-minute walk test. The Functional Status Index showed reduced levels of functional performance in fracture subjects compared with controls with increased levels of assistance, pain with activity, and difficulty in activities. Psychosocial performance was limited in fracture subjects with increased psychiatric symptoms, increased pain, and greater perception of problems caused by health. CONCLUSION Vertebral compression fractures are associated with significant performance impairments in physical, functional, and psychosocial domains in older women.

Pain coping skills training in the management of osteoarthritic knee pain: A comparative study

The purpose of this study was to determine whether a cognitive-behavioral intervention designed to improve pain coping skills could reduce pain, physical disability, psychological disability, and pain behavior in osteoarthritic knee pain patients. Patients in this study were older adults (mean age=64 years) having persistent pain (mean duration=12 years), who were diagnosed as having osteoarthritis of the knee on the basis of medical evaluation and x-rays. Patients were randomly assigned to one of three conditions: pain coping skills training, arthritis education, or a standard care control condition. Patients in the pain coping skills training condition (n=32) attended 10 weekly group sessions training them to recognize and reduce irrational cognitions and to use attention diversion and changes in activity patterns to control and decrease pain. Arthritis education subjects (n=36) attended 10 weekly group sessions providing them with detailed information on osteoarthritis. Standard care control subjects (n=31) continued with their routine care. Measures of coping strategies, pain, psychological disability, physical disability, medication use, and pain behavior were collected from all subjects before and after treatment. Results indicated that patients receiving pain coping skills training had significantly lower levels of pain and psychological disability post-treatment than patients receiving arthritis education or standard care. Correlational analyses revealed that patients in the pain coping skills training group who reported increases in the perceived effectiveness of their coping strategies were more likely to have lower levels of physical disability post-treatment. Taken together, these findings indicate that pain coping skills training can reduce pain and psychological disability in osteoarthritis patients. Future studies should examine whether behavioral rehearsal or spouse training can strengthen the effects of pain coping skills training in order to reduce physical disability and pain behavior as well as pain and psychological disability.

Traumatic Anterior Atlanto-occipital Dislocation

The five cases of atlanto-occipital dislocation reported in the world literature are reviewed, and four additional cases are presented, including two survivors. The pathological anatomy of this potentially catastrophic injury and its management are briefly discussed. Because immediate recognition of the atlanto-occipital dislocation is critical to proper treatment and because the neurological findings are extremely varied, a new radiographic criterion for its identification has been developed.

Osteoarthritic knee pain: a behavioral analysis.

&NA; This study used behavioral assessment techniques to analyze pain in osteoarthritis (OA) patients. Elghty‐seven OA patients having chronic knee pain served as subjects. Pain behavior was evaluated using a standard observation method and functional impairment was assessed using the Arthritis Impact Measurement Scales. Data analysis revealed that pain and limitations in physical activities were the most common functional impairments and that the most frequently observed pain behavior was guarded movement. Predictive analyses indicated that disability support status and scores on a Pain Control and Rational Thinking factor of the Coping Strategies Questionnaire (CSQ) were predictive of functional impairment. Patients receiving disability support payments were much more functionally limited than those not receiving this financial support. Patients scoring high on the Pain Control and Rational Thinking factor of the CSQ were much less functionally impaired, walked a 5 m course more rapidly and moved from a standing to a sitting or reclining position more quickly than patients scoring low on this factor. The implications of these results for behavioral treatment of OA knee pain are discussed.

An Explanation for Various Rectus Femoris Strain Injuries Using Previously Undescribed Muscle Architecture

We performed cadaveric dissection of the rectus femo ris muscle to correlate the various lesions of strain injury seen with imaging studies to the muscular anatomy. The proximal tendon is composed of a superficial, an terior portion from the direct head, and a deep intra muscular portion from the indirect head. The muscle fibers arising from the anterior superficial tendon of the direct head travel in a posterior and distal direction to insert on the posterior tendon of insertion, giving the proximal muscle a unipennate architecture. Muscle fi bers from the intramuscular tendon of the indirect head originate on both the medial and lateral sides of the tendon and insert on the distal posterior tendon to cre ate its bipennate structure. Three chronic strain injuries involving the midmuscle belly substance were explored grossly and microscopically. It appears that one type of acute strain injury occurs in the midmuscle belly with disruption of the muscle-tendon junction of the intra muscular tendon resulting in local hemorrhage and edema. More chronically, this hematoma organizes into a fatty, loose connective tissue encasement of the deep intramuscular proximal tendon. Serous fluid from the hematoma may remain within the connective tissue sheath, creating a pseudocyst with the deep intra muscular tendon of the indirect head at its center. The muscles anatomy helps to explain a different rectus femoris strain injury.

Radiographic and geometric anatomy of the scapula.

In an effort to study anatomic parameters of the scapula that may be of clinical importance, scapulae were harvested from cadavers and stripped of their soft tissues. For each scapula, three roentgenograms then were obtained: a Y-scapular view, an axillary lateral view, and a glenoid fossa (or true anteroposterior) view. Computed tomographic pneumoarthrograms and randomly selected antero-posterior chest roentgenograms of skeletally mature adults were studied also to measure further roentgenographic parameters of the normal scapula. The geometric anatomy of the scapula is of fundamental importance in the pathomechanics of rotator cuff disease, total shoulder arthroplasty, and recurrent shoulder dislocation. This study presents in detail the exact geometry of scapula anatomy, giving precise figures for distances, angles, and radii of curvature of the scapula. All results then are discussed in terms of their clinical relevance to the above problems.

Analyzing pain in rheumatoid arthritis patients. Pain coping strategies in patients who have had knee replacement surgery

&NA; This study used the Coping Strategies Questionnaire (CSQ) to investigate pain coping strategies in 52 rheumatoid arthritis patients who reported having knee pain 1 year or more following knee replacement surgery. Data analysis revealed that, as a group, these patients were active copers in that they reported frequent use of a variety of pain coping strategies. Pain coping strategies were found to be related to measures of pain and adjustment. Patients who rated their ability to control and decrease pain high and who rarely engaged in catastrophizing (i.e., who scored high on the Pain Control and Rational Thinking factor of the CSQ) had much lower levels of pain and psychological disability than patients who did not. Coping strategies were not found to relate to age, gender, obesity status or disability/compensation status. Taken together, these results suggest that an analysis of pain coping strategies may be helpful in understanding pain in arthritis patients who have pain following joint replacement surgery.

Pyomyositis in a temperate climate. Presentation, diagnosis, and treatment.

The cases of eighteen patients who were treated for pyomyositis between 1970 and 1988 were evaluated. The diagnosis was often delayed because other primary diagnoses were considered, including muscle strain, synovitis, thrombophlebitis, and neoplasm, and because the symptoms were vague and prolonged (maximum duration, one year). The muscles around the hip and thigh were most commonly involved (twelve patients), and Staphylococcus aureus most commonly grew on culture (twelve patients). Computed tomography aided in the accurate diagnosis of the infection and of the extent of involvement. Incision, drainage, and antibiotic therapy eradicated the infection in all patients, and they had no residual functional limitations and minimum residual symptoms.

Calcification of Entheses Associated with X-Linked Hypophosphatemic Osteomalacia

We undertook a retrospective analysis of 26 patients with X-linked hypophosphatemic osteomalacia (or rickets), whose ages ranged from 1 to 62 years and who were from 11 different kindreds, to determine the prevalence and clinical characteristics of a unique disorder of the entheses (tendons, ligaments, and joint capsules). We found a generalized involvement of the entheses, with exuberant calcification of tendon and ligament insertions and of joint capsules, in 69 per cent of the subjects. The prevalence and extent of disease increased with age but were not correlated with sex. Commonly affected sites included the hand and sacroiliac joints. Histologic evaluation in a selected patient revealed intratendinous lamellar bone but no inflammatory cells. Our observations indicate that this disorder is an integral part of X-linked hypophosphatemic osteomalacia and exhibits clinical, radiographic, and histologic characteristics that differentiate it from degenerative disorders of these tissues and seronegative spondyloarthropathies.

Pain measurement in elders with chronic low back pain: Traditional and alternative approaches

&NA; Pain evaluation typically relies upon the use of self‐report instruments. The validity of these tools is questionable in many older adults, however, particularly those with cognitive impairment. Rating of pain behavior (e.g. grimacing, sighing) by an objective observer represents an alternative pain assessment strategy which has been validated in subjects of heterogeneous ages. The purpose of this study was to examine, in a group of community‐dwelling elderly with low back pain and lumbosacral osteoarthritis, the concurrent validity of observational pain behavior rating techniques as compared with self‐report instruments and the degree to which pain and pain behavior relate to disability. Thirty‐nine cognitively intact subjects, age >65 years, without depression, other sources of pain, or other known spinal pathology underwent the following measures: (1) pain self‐report using the verbal 0–10 scale, vertical verbal descriptor scale, Arthritis Impact Measurement Scales and McGill Pain Questionnaire; (2) pain behavior was sampled during two protocols, one, identical to that used by Keefe and Block (Behav. Ther., 13 (1982) 363–375), that required subjects to sit, stand, walk, and recline for 1–2 minute periods (which we have labelled the traditional protocol), and a second, more demanding protocol that was designed to simulate activities of daily living that place a premium on axial movement (the ‘ADL’ protocol); (3) disability was assessed using the Roland questionnaire, a 6 month global disability question and the Jette Functional Status Index; and (4) radiographic evaluation of the lumbosacral spine; osteoarthritis was quantitated using a previously validated scoring system. Interrelationships among pain, pain behavior and disabilityv measures were tested using canonical correlations. Self‐reported pain was associated with pain behavior frequency; the association was stronger when the ADL protocol was used, as compared with the traditional protocol. The association between pain and disability was modestly strong with both self‐report instruments and pain behavior observation when the ADL protocol was used, but not when the traditional protocol was used. Our findings suggest that pain behavior observation is a valid assessment tool in the elderly. In addition, it seems that observation of elders during performance of activities of daily living may be a more sensitive and valid way of assessing pain behavior than observing pain behavior during sitting, walking, standing, or reclining.
