Measurement of three-joint-finger motions: reality or fancy? A three-dimensional anatomical approach.

Various anatomical publications have reported two-dimensional studies with flexion/extension or abduction/adduction motion analysis, but longitudinal axial rotations (LAR) of three-joint fingers have rarely been mentioned. The aim of our study was to determine the maximal passive motions of three-joint-fingers and to measure the passive LAR of phalanges during a flexion/extension movement. A protocol of anatomical dissection was carried out with 22 fresh-frozen limbs from 11 human cadavers free from any visible pathology. The sample consisted of six females and five males with a mean age of 75.7 years (range 65-94 years). Passive motions of fingers excluding the thumb were analyzed with a wire circling technique. Extreme flexion/extension angles and adduction/abduction laxities were measured for each joint. LAR angles of distal bony segment position were evaluated in comparison with the proximal bony segment position in extreme flexion or extension. The results were recorded for the joints of each three-joint-finger. No difference was statistically related to sex or right/left-sided criteria ( p>0.05). Passive LARs were measured in spite of an aggressive anatomical protocol. A small database was set up. LARs were an important third type of motion. They should be analyzed during a routine clinical examination of patients' hands as well as flexion/extension or abduction/adduction motions.

MRI of the wrist and finger joints in inflammatory joint diseases at 1-year interval: MRI features to predict bone erosions.

The aim of this study was to assess the ability of MRI determined synovial volumes and bone marrow oedema to predict progressions in bone erosions after 1 year in patients with different types of inflammatory joint diseases. Eighty-four patients underwent MRI, laboratory and clinical examination at baseline and 1 year later. Magnetic resonance imaging of the wrist and finger joints was performed in 22 patients with rheumatoid arthritis less than 3 years (group 1) who fulfilled the American College of Rheumatology (ACR) criteria for rheumatoid arthritis, 18 patients with reactive arthritis or psoriatic arthritis (group 2), 22 patients with more than 3 years duration of rheumatoid arthritis, who fulfilled the ACR criteria for rheumatoid arthritis (group 3), and 20 patients with arthralgia (group 4). The volume of the synovial membrane was outlined manually before and after gadodiamide injection on the T1-weighted sequences in the finger joints. Bones with marrow oedema were summed up in the wrist and fingers on short-tau inversion recovery sequences. These MRI features was compared with the number of bone erosions 1 year later. The MR images were scored independently under masked conditions. The synovial volumes in the finger joints assessed on pre-contrast images was highly predictive of bone erosions 1 year later in patients with rheumatoid arthritis (groups 1 and 3). The strongest individual predictor of bone erosions at 1-year follow-up was bone marrow oedema, if present at the wrist at baseline. Bone erosions on baseline MRI were in few cases reversible at follow-up MRI. The total synovial volume in the finger joints, and the presence of bone oedema in the wrist bones, seems to be predictive for the number of bone erosions 1 year later and may be used in screening. The importance of very early bone changes on MRI and the importance of the reversibility of these findings remain to be clarified.

169Erbium-citrate synoviorthesis after failure of local corticosteroid injections to treat rheumatoid arthritis-affected finger joints.

OBJECTIVES: Intra-articular injection of 169Erbium-citrate (169Er-citrate; radiosynoviorthesis or radiosynovectomy) is an effective local treatment of rheumatic joint diseases. However, its efficacy in corticosteroid-resistant rheumatoid arthritis-affected joints has not been clearly demonstrated. METHODS: A double-blind, randomised, placebo-controlled, international multicentre study was conducted in patients with rheumatoid arthritis with recent (< or = 24 months) ineffective corticosteroid injection(s) into their finger joint(s). Eighty-five finger joints of 44 patients were randomised to receive a single injection of placebo (NaCl 0.9%) or 169Er-citrate. Results of evaluation 6 months later were available for 82 joints (46 metacarpophalangeal and 36 proximal interphalangeal joints) of 42 patients: 39 169Er-citrate-injected joints and 43 placebo-injected joints. Efficacy was assessed using a rating scale for joint pain, swelling and mobility. RESULTS: Intent-to-treat analysis of the results of the 82 joints showed a significant effect of 169Er-citrate compared to placebo for the principal criteria decreased pain or swelling (95 vs 79%; p = 0.038) and decreased pain and swelling (79 vs 47%; p = 0.0024) and for the secondary criteria decreased pain (92 vs 72%; p = 0.017), decreased swelling (82 vs 53%; p = 0.0065) and increased mobility (64 vs 42%; p = 0.036). Per-protocol analysis, excluding 18 joints of patients who markedly changed their usual systemic treatment for arthritis, gave similar percentages of improvement but statistical significance was lower owing the reduced power of the statistical tests. CONCLUSION: These results confirm the clinical efficacy of 169Er-citrate synoviorthesis of rheumatoid arthritis-diseased finger joints after recent failure of intra-articular corticotherapy.

A test procedure for artificial finger joints.

This paper highlights the lack of an agreed testing standard for artificial finger joints. It reviews the anatomy, pathology and biomechanics of finger joints as well as the various designs of finger prostheses and the machines used to test them. While pre-implantation testing should be fundamental, increasing regulation of the biomedical engineering industry will further demand testing of prostheses to pre-agreed standards. Standards relating to the testing of other artificial joints are reviewed before possible parameters for testing finger prostheses are offered.

Finger joint swelling: correlation with age, gender, and manual labor.

A soft tissue immersion radiography technique was used to study changes in 4,648 finger joints of 166 patients free from signs of inflammatory joint disease. An age-specific correlation was found for joint swelling, joint space narrowing, joint margin spurs, and intraarticular loose bodies. The distal interphalangeal joints were more commonly swollen in women, and the proximal interphalangeal and metacarpophalangeal joints more commonly swollen in manual laborers. Both correlations are highly significant (P less than 0.001). The second and third digits showed a definite predilection for joint swelling. Swelling of finger joints is closely correlated with age and degenerative disease, and its occurrence in older patients is associated with degenerative changes. In manual laborers it should not be interpreted as evidence for inflammatory joint disease.

Fractal analysis of acceleration signals from patients with CPPD, rheumatoid arthritis, and spondyloarthroparthy of the finger joint.

Arthritis is one of the leading causes of disability and affects a major segment of the population. Consequently, accurate diagnosis of arthritis is important. Arthritis due to calcium pyrophosphate deposition disease (CPPD), rheumatoid arthritis, and spondyloarthropathy, induce complex changes in the cartilage and the articular surface. The fractal dimension provides a measure of the complexity of a signal. Recently, we have developed non-invasive acceleration measurements to characterize the arthritic patients. The question remains if the fractal dimension of the acceleration signal is different for different arthritis conditions. The purpose of this study was to distinguish between different types of arthritis of the finger joint using the fractal dimension of the acceleration signal obtained from the finger joint of the arthritic patients. Acceleration signals were obtained from the finger joint of arthritis patients with rheumatoid arthritis, spondyloarthropathy, and calcium pyrophosphate deposition disease of the finger joint. ANOVA results showed that there were significant differences between the fractal dimension of acceleration signals from patients having calcium pyrophosphate deposition disease and rheumatoid arthritis and spondyloarthropathy. Fractal dimension of acceleration signals, in concert with other clinical symptoms, can be used to classify different types of arthritis.

Arthritis of the finger joints: a comprehensive approach comparing conventional radiography, scintigraphy, ultrasound, and contrast-enhanced magnetic resonance imaging.

OBJECTIVE: A prospective study was performed comparing conventional radiography, 3-phase bone scintigraphy, ultrasound, and magnetic resonance imaging (MRI) with precontrast and dynamic postcontrast examinations in 60 patients with various forms of arthritis including rheumatoid arthritis (RA), spondyl-arthropathy, and arthritis associated with connective tissue disease. METHODS: A total of 840 finger joints were examined clinically and by all 4 imaging methods. Experienced investigators blinded to the clinical findings and diagnoses analyzed all methods independently of each other. The patients were divided into 2 groups. Group 1 included 32 patients (448 finger joints) without radiologic signs of destructive arthritis (Larsen grades 0-1) of the evaluated hand and wrist and group 2 included 28 patients (392 finger joints) with radiographs revealing erosions (Larsen grade 2) of the evaluated hand and/or wrist. RESULTS: Clinical evaluation, scintigraphy, MRI, and ultrasound were each more sensitive than conventional radiography in detecting inflammatory soft tissue lesions as well as destructive joint processes in arthritis patients in group 1. All differences were statistically significant. We found ultrasound to be even more sensitive than MRI in the detection of synovitis. MRI detected erosions in 92 finger joints (20%; 26 patients) in group 1 that had not been detected by conventional radiography. CONCLUSION: Our data indicate that MRI and ultrasound are valuable diagnostic methods in patients with arthritis who have normal findings on radiologic evaluation.

Preserved and foreign cartilage interpositional materials for silastic finger joint implant arthroplasty.

Cartilage grafts were implanted as interpositional materials (IPMs) around the stems of silicone finger joint prostheses to protect their surfaces from abrasion with the local bone tissue. The knee joints of New Zealand White rabbits were implanted with finger joint prostheses and grafted with preserved auto- and allografts as well as fresh xenografts. Data were obtained after one month and compared to controls that received only the silicone prostheses. The grafting procedures did not cause any variations in joint function or differences in the amount of lipids absorbed by the prosthesis. A thin fibrous capsule formed about the control implants, whereas the capsules of the grafted legs were greater in thickness and area. Gross examination of the implant surfaces, weight analyses, and light microscopic studies of the number of wear particles found in the surrounding tissue capsules all indicated a reduction in prosthetic wear with grafting. The cartilage grafts were surrounded by inflammatory cells and were losing their proteoglycans. As expected, the xenografts exhibited the most degradation. No differences were noted between the preserved grafts. These results indicate that at one month, cartilage has provided protection for early implant motion. The biodegradable graft was being replaced by fibrous connective tissue. Long-term protection needs to be studied in additional experiments.

Vascularized toe-to-finger joint transplantation. 11 patients followed for 4 years.

Since 1983, we have transplanted 11 free vascularized joints in 8 men and 3 women, mean age 32 years. The causes of joint involvement were trauma in 9 cases and infection in 2. One MP and 10 PIP joints of the second toe were transplanted to 3 MP and 8 PIP joints of the fingers. After a mean postoperative follow-up period of 4 years, the mean postoperative range of motion was 31 degrees compared with 16 degrees preoperatively. Radiographs showed destruction of 4 PIP joints, probably caused by vascular failure in 2 joints and infection in 2. In spite of no evidence of arthrosis, some of the joints had gradually undergone a loss of extension. Although there are some problems that should be overcome, we advocate a free vascularized toe-joint transplantation for severe finger-joint destruction without extensive surrounding soft-tissue damage.

[Correlation between degenerative changes of the thoracic spine and the finger joints--a roentgenological study in generalized osteoarthrosis].

PURPOSE: Different studies in patients with rheumatoid arthritis demonstrated a correlation between degenerative changes of the cervical spine and peripheral joints. The aim of study therefore was to assess the relations of degenerative changes of the cervical spine and peripheral joints. METHODS: 106 patients suffering on Generalized Osteoarthritis were examined by standard radiography of the hands and cervical spine. All images were evaluated according to Kellgren grades. The mean values of the cervical spine and finger joints were compared in three calculations, for this purpose the finger joints were "segmental", "functional" and randomized arranged. RESULTS AND CONCLUSIONS: Concerning quality and quantity the highest correlation was observed in the group of the so-called "segmental-arrangement". Therefore a association between the cervical spine and the finger joints seems possible relating to manifestation, pattern and graduation of degenerative processes. At this stage there is no statement possible about the direction of the correlation.

[Septic arthritis of the finger joints. Treatment with immediate arthrodesis].

A consecutive series of 44 patients with septic arthritis of finger joints is presented. The patients were treated with antibiotics, incision, debridement and usually drainage. In 13 patients with destruction of the joint cartilage, an arthrodesis was made at the time of incision. The failure rate with conventional therapy was 42 per cent. The failure rate in the arthrodesis group, which represented all the severe cases, was 23 per cent. In septic arthritis of finger joints with destruction of the cartilage arthrodesis with Kirschner-wire and interosseous wiring is recommended at the time of primary incision.

A novel ultrasonographic synovitis scoring system suitable for analyzing finger joint inflammation in rheumatoid arthritis.

OBJECTIVE: To develop an ultrasonographic (US) synovitis scoring system suitable for evaluation of finger joint inflammation in patients with active rheumatoid arthritis (RA) and to compare semiquantitative US scoring with quantitative US measurements. METHODS: US was performed at the palmar and dorsal sides of the second through fifth metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints in 10 healthy subjects and in the clinically more affected hand in 46 RA patients. Ten patients additionally underwent magnetic resonance imaging (MRI). Synovitis was measured, standardized, and scored according to a semiquantitative method. The 2 methods (semiquantitative US scoring, quantitative US) were compared and statistical cutoffs were identified using receiver operating characteristic (ROC) curve analysis. MRI results were compared with semiquantitative US scoring and quantitative US results. The optimal US scoring method from 6 joint combinations was identified (ROC curve analysis). RESULTS: Synovitis was most frequently detected in the palmar proximal area (86% of affected joints). We found no significant differences between individual PIP joints or between individual MCP joints, indicating that all fingers within each of these joint groups should be treated equally for statistical calculations, although each joint group as a whole should be treated separately. The optimal cutoff point to distinguish between "health" and "pathology" was 0.6 mm both for MCP joints (sensitivity 94%, specificity 89%) and for PIP joints (sensitivity 90%, specificity 88%). There was no significant difference between semiquantitative US scores and quantitative US measurements. The best results for joint combinations were achieved using the "sum of 4 fingers" (second through fifth MCP and PIP joints) and "sum of 3 fingers" (second through fourth MCP and PIP joints) methods. Comparison of MRI results with semiquantitative US scores revealed high concordance. CONCLUSION: US evaluation of finger joint synovitis can be considerably simplified by focusing on the palmar side and by applying semiquantitative grading instead of quantitative measurements. For evaluation of treatment efficacy based on synovitis in RA patients, we recommend using the "sum of 3 fingers" method in longitudinal trials.

Lateral digital photography with computer-aided goniometry versus standard goniometry for recording finger joint angles.

This study compares the accuracy of computer-aided goniometry with standard goniometry. 109 finger joint angles at the extremes of flexion and extension were measured by a senior hand therapist using standard goniometry. Lateral digital photographs were then taken of the hands and the same angles were read from these by computer. There was good correlation (r(2)=0.975) between the results. Computer goniometry averaged 1 degrees (95%Cl=0 degrees -+2 degrees ) more than the standard goniometry. We feel that computer goniometry of finger joints is accurate and compares well with standard goniometry.

Pre- and postimplantation dynamic mechanical properties of silastic HP-100 finger joints.

Dynamic mechanical properties of Silastic HP-100 finger joint implants were studied. Sixteen sections of unimplanted and 14 sections of retrieved implants were analyzed with standard thermal analysis techniques. Results show that implantation does not alter the viscoelastic properties of Silastic HP-100 elastomers. The authors conclude that fracture of Silastic HP-100 implants cannot be attributed to changes in rheologic properties of the implanted elastomer.
