[Treatment of hygroma in children].

Treatment of 192 children for hygromas of various localization by different methods is analysed. The results of histological examination showed these structures to be of dysplastic nature. An aspiration-cystotatic method of treatment was developed, which can be applied in outpatient practice and causes neither local nor general complications.

Kinematics of the first metatarsophalangeal joint.

The kinematics of both the first metatarsophalangeal joint and the articulation of the hallux sesamoid bones with the metatarsal head were investigated with fifteen fresh-frozen below-the-knee amputation specimens using a radiographic technique. Six feet were of normal structural anatomy, six displayed hallux valgus, and three had hallux rigidus. Normal specimens demonstrated an average total range of motion in the sagittal plane of 111 degrees, with about 76 degrees of dorsiflexion and 34 degrees of plantar flexion. The abnormal specimens revealed a decreased total arc of motion, with a limitation of plantar flexion in feet with hallux valgus and a loss of dorsiflexion in feet with hallux rigidus. Motion analysis of the normal metatarsophalangeal joints demonstrated minimum scattering of instant centers of rotation. This was in contrast to the diseased articulations, which displayed markedly displaced instant centers of rotation located eccentrically about the metatarsal head. Surface motion in the normal joints was characterized as tangential sliding from maximum plantar flexion to moderate dorsiflexion, with some compression at maximum dorsiflexion. The feet with hallux valgus and the feet with hallux rigidus displayed distinctive patterns of distraction and jamming throughout specific portions of the range of motion in the sagittal plane. Motion of the metatarsophalangeal joint in the transverse plane concomitant with motion in the sagittal plane, which has been hypothesized by other investigators, was confirmed and quantified in this study. The feet with hallux rigidus displayed a reduction in this motion.(ABSTRACT TRUNCATED AT 250 WORDS)

Silicone lymphadenitis secondary to implant degeneration.

The principal objective(s) of this presentation is to report a case of lymphadenitis secondary to implant degeneration. A review of the literature on the history and development of the silicone implant and the durability of the silicone elastomer is presented. A case report with radiologic and histologic documentation is also presented. Silicone lymphadenitis is a rare occurrence and the authors believe they have reported the first case to occur in the lower extremity.

Functional limitation of motion of the first metatarsophalangeal joint.

The primary conditions characterized by functional limitation of motion of the first metatarsal are hallux limitus and hallux rigidus. The authors discuss the etiology, clinical manifestations, biomechanical compensatory mechanisms, and radiographic findings. Because only temporary relief is provided by conservative treatment, the various surgical approaches to treatment are discussed.

[Erbium 169 synoviortheses and infiltrations of triamcinolone hexacetonide in metatarsophalangeal arthritis of chronic inflammatory rheumatism].

The authors report their experience in the treatment of metatarsophalangeal arthritis of chronic inflammatory rheumatism by Erbium 169 synoviortheses (112 joints treated) and by infiltrations of triamcinolone hexacetonide (53 joints treated). The steroid appears to have a marked early superiority as it gives 85% good results compared to 61.6% for Erbium 169 after a period of one to three months. However, its results then deteriorate more rapidly and after 6 months, the proportion of good results is greater with the radioactive treatment (64% compared to 46.7%). The authors consider it reasonable to use triamcinolone hexacetonide as the first line treatment as it is easier to manage and less expensive, reserving the radioactive synoviortheses for later with the prospect of more lasting results.

A postsurgical evaluation of hemi-implant procedures at the first metatarsophalangeal joint: review and comparison of eighteen cases.

This presentation summarizes the results discovered on implantation surgery of 18 digits on 16 patients for correction of hallux limitus, or hallux rigidus. Of those studied, 66.7% received excellent and good results, 22.2% had fair results, and 11.1% had poor results. Comparison with the literature shows good correlation between studies and allows for quantification of the probability of positive returns on this form of surgery.

Acute gouty arthritis in a first metatarsophalangeal joint replaced with a flexible-hinge implant: a case report.

Use of the flexible-hinge, double-stemmed implant has eliminated many of the complications that followed correction of an arthritic first metatarsophalangeal joint caused by hallux valgus. There were no reports in the literature of acute gout after this type of correction. The authors present such a case in a patient with a history of gout, and they suggest that, when a synovectomy is performed in a patient with gouty arthritis, the joint should be freed of synovial tissue in which a uric acid crystal-induced synovitis could occur.

Modified medial column arthrodesis.

This manuscript describes a modified medial column arthrodesis involving the medial and intermediate naviculocuneiform joints, the first metatarsocuneiform joint and the first intercuneiform joint. Medial column stabilizing procedures are usually advocated as a component part of a generalized hypermobile flatfoot repair. This procedure, however, is being recommended for elderly or sedentary individuals who have medial column pain, difficulty ambulating and problems wearing standard foot gear secondary to end-stage medial column degenerative joint disease and medial column collapse.

Surgery for adolescent hallux valgus.

Attention is directed to the large number of operations for the correction of hallux valgus in the adolescent and important variations among the most popular surgical procedures, as well as the factors influencing the outcome of these operations. A consistently reliable operation is the modified Wilson procedure, a metatarsal shaft osteotomy. Its merits are its technical simplicity, minimal damage to soft tissue, and pleasing correction of deformity. The operation narrows the forefoot, relaxes soft tissues, and maintains excellent mobility of the first metatarsophalangeal joint.

The course of radiologic damage during the first six years of rheumatoid arthritis.

OBJECTIVE: To describe the radiologic course in a large cohort of patients with early rheumatoid arthritis (RA) and to analyze individual components of damage. METHODS: Five hundred two patients with recent-onset RA (disease duration <1 year) underwent annual radiologic assessment for a maximum of 6 years in this longitudinal prospective study. The study was designed to investigate the efficacy of 3 different therapeutic strategies. For the assessment of radiologic damage, radiographs of the hands and feet were scored according to the modified Sharp/van der Heijde method (SHS; range 0-448). A mean of 2.9 (range 1-7) radiographs was read per patient. RESULTS: Stable rates of progression of the SHS, erosion score, and narrowing score were found over the course of RA: the mean rates were 8.6, 5.4, and 3.2 modified Sharp units per year, respectively. The rate of progression of newly (not previously) damaged joints declined, and the rate of progression of already damaged joints (which became more damaged) increased during followup, leading to an equal contribution to progression of the SHS at 5 years. The joints of the feet, especially the fifth metatarsophalangeal joint, generally became eroded earlier and more of them became eroded compared with the joints of the hands. CONCLUSION: Radiologic damage progresses at a constant rate. In advanced disease, monitoring the progression of previously existing damage is as important as assessing new abnormalities in previously undamaged joints. Radiographs of the feet should be included in assessments of radiologic damage that are used in clinical intervention trials and daily practice.

A method to score radiographic change in psoriatic arthritis.

INTRODUCTION: Radiographic features of psoriatic arthritis (PsA) are very characteristic and differ from those observed in rheumatoid arthritis, especially in two aspects: 1) the distribution of affected joints (i.e. DIP joints), 2) the presence of destructive changes and bone proliferation at the same time. A scoring method for PsA, therefore, has to account for these characteristics of PsA. OBJECTIVE: To develop, describe and validate a method for scoring radiographic changes in patients with PsA. DESCRIPTION OF THE METHOD: Forty joints of the hands and feet are scored for destruction and proliferation. In the destruction score (DS) grading on a 0-5 scale is based on the amount of joint surface destruction: 0 = normal, 1 = one or more erosions with an interruption of the cortical plate of > 1 mm with destruction of the total joint surface up to 10%, 2 = 11-25%, 3 = 26-50%, 4 = 51-75%, 5 = > 75% joint surface destruction. The proliferation score (PS) sums up any kind of bony proliferation typical for PsA; graded 0-4: 0 = normal, 1 = bony proliferation of 1-2 mm or bone growth < 25% of the original size (diameter), 2 = bony proliferation 2-3 mm or bone growth 25-50%, 3 = bony proliferation > 3 mm or bone growth > 50%, 4 = bony ankylosis. The DS (0-200) and the PS (0-160) can be summed up to the total score (0-360). VALIDATION OF THE METHOD: To validate the method x-rays of 20 patients with active PsA taken 3 years apart were read twice in pairs, knowing the chronological order but not knowing demographic, clinical or laboratory data of the patients. The data were analyzed with a hierarchical analysis of variance model. RESULTS: There was good agreement between the first and the second reading of the same rater and between the two raters regarding the destruction score. The agreement regarding the proliferation score was lower but still acceptable. The reliability of the method to describe change over time--relation of progression (intra-patient variance) to the measurement error (inter-rater variance)--was 3.9 for the DS, 2.8 for the PS and 4.1 for the total score. The minimal detectable change when the readings of two raters were compared (inter-rater MDC) was 5.8, 5.0 and 4.6%, respectively of the maximum possible score for the destruction, the proliferation and the total score. These data compare very well with the results of standard scoring methods in rheumatoid arthritis. CONCLUSION: We propose a method for scoring radiographic change in psoriatic arthritis which reliably quantifies the progression of the disease seen on radiographs.
