Sternoclavicular infectious arthritis in previously healthy adults.

OBJECTIVE: To define characteristics of sternoclavicular infection (SCI) in previously healthy patients. METHODS: SCI in a previously healthy man is reported along with 4 similar cases found by surveying the hospital's database; 22 previously reported cases were culled from the literature and summarized. RESULTS: The frequency of SCI in healthy adults was 0.5% of all bone and joint infections admitted to the hospital. The clinical and bacteriologic features were similar to previous reports in nonselected SCI patients. Computerized tomography (CT) scan, arthrocenthesis, and biopsy were required for diagnosis. Complications included abscess formation, mediastinitis, and sepsis. The majority of patients were treated by surgical drainage and antibiotics. The final outcome was good, without mortality or long-term morbidity. CONCLUSIONS: Although SCI is a rare infection in healthy adults, it should be considered in the differential diagnosis of a painful sternoclavicular joint. Prompt diagnosis and appropriate treatment of SCI results in excellent outcome in most cases.

Complete posterior sternoclavicular epiphyseal separation. A case report and review of the literature.

A review of the literature shows that fractures of the medial clavicular physis rarely occur. Fractures of the medial clavicular physis was diagnosed in a 14-year-old boy. Bony closure of this physis may not be complete until as late as 25 years of age. Complete fracture-separations of this physis, with posterior displacement into the mediastinum, should be included in the differential diagnosis of children and any young adult patients with an apparent posterior sternoclavicular dislocation.

Evolution of chronic recurrent multifocal osteitis toward spondylarthropathy over the long term.

OBJECTIVE: To retrospectively assess, with a sufficiently long followup (mean 11.6 years; median 9 years), the long-term outcome of chronic recurrent multifocal osteitis (CRMO), a multifocal, inflammatory bone disease. METHODS: Patients included were 8 children/adolescents and 7 adults with no family history of rheumatic disease who had been diagnosed as having CRMO between 1979 and 1995. Ten patients had undergone at least 1 bone biopsy of the lesions, with histologic examination and multiple cultures. In 1996, in addition to an in-depth interview, 12 patients underwent an extensive physical examination, laboratory evaluation, HLA-A, B, C, and DR typing, bone radiography and scintigraphy, and computed tomography scan of the sternoclavicular and sacroiliac joints. RESULTS: Remission was observed in 3 patients. The other 12 patients developed various associations of vertebral (n = 10), sacroiliac (n = 6), anterior thoracic (n = 7), peripheral articular (n = 2), enthesopathic (n = 4), or dermatologic (palmoplantar pustulosis in 3 cases and psoriasis in 2) involvements. Spine involvement was the most common and occurred the earliest (median time to appearance after the onset of osteitis 5.63 years). Clinical sacroiliitis was always unilateral. No patients carried the HLA-B27 haplotype. CRMO responded well to nonsteroidal antiinflammatory drugs. Twelve patients met the European Spondylarthropathy Study Group criteria for spondylarthopathy. CONCLUSION: After 10 years, CRMO had usually evolved to spondylarthropathy, but with certain features not usually seen in the latter: predominantly, unilateral sacroiliitis, no familial form, and no link with HLA-B27.

Arthropathy associated with palmoplantar pustulosis.

A survey of 170 patients with a diagnosis of palmoplantar pustulosis (PPP) has been undertaken. Detailed family histories of our patients were compiled, dermatological and rheumatological examinations were made. Radiography was performed in patients with clinical suspicions of spinal and/or sacroiliacal, sternoclavicular and sternocostal joint involvement. Active chest-wall symptoms were screened by scintigraphy. Twenty-five patients (16 females, 9 males, with an age range of 32-66, mean 51 years) had some rheumatic complaints. Fifteen of them (60%) had anterior chest-wall involvement, 6 (24%) sacroiliitis (3 of whom also had AS) and 11 (44%) peripheral arthropathy. Six other patients suffered from transient and migratory joint pain. The joint disease was mild in all but 6 cases. Laboratory tests showed increased ESR in 6 patients (24%); only 3 of these patients had elevated CRP. A slightly elevated haptoglobin and/or orosomucoid were found in 12 cases (48%). Elevated IgA was present in 4, IgG in 2 and IgM in 1 patient. Fungal and bacteriological cultures of the skin were negative. A family history of psoriasis was present in 4 patients (16%), of psoriatic arthropathy in 1 patients (4%) and of PPP in 2 patients (8%). Six patients (24%) had concomitant psoriasis. No association between PPP H1a-AC antigens was found. A high incidence of HLA-B27 antigen, present in 8 patients (32%), was documented. A similar association with HLA-B27 has been found in patients with psoriatic arthritis (16). The feeble association with HLA-B13,-17,-37 and CW6 found in psoriasis was not present.(ABSTRACT TRUNCATED AT 250 WORDS)

[Sternocostoclavicular hyperostosis--case reports and differential diagnosis].

Sternocostoclavicular hyperostosis (SCCH) is a disorder related to collagenoses. SCCH is typically characterised by the triad of swelling of the sternoclavicular and/or sternocostal joints of the first or second rib, palmar and plantar pustulosis (PPP), only limited elevation of inflammation indicating laboratory parameters. Till today the etiology is unclear and no causal therapy is known. Symptomatic treatment consists of administration of NSAID and cortisone, irradiation and even limited resection of the clavicle and rib.

Panclavicular ankylosis in pustulotic arthroosteitis. A case report.

A 54-year-old man who had palmoplantar pustulosis showed bilateral, complete osseous fusion of the sternoclavicular and acromioclavicular joints. No significant abnormality was seen in the glenohumeral joint. The left clavicle had a nonunion develop, whereas the right did not. The elevation of the right shoulder was limited to 100 degrees in active and passive measurements. The total external rotation and internal rotation at the side was 135 degrees. This decreased to 90 degrees at 60 degrees elevation and to 10 degrees at maximum (100 degrees) elevation. Based on the kinematic data on normal shoulders, it was thought that the ankylosis of both ends of the clavicle held the scapula unrotated during the arm movement so that, at the arm to trunk angle of 100 degrees, the position of the humerus relative to the scapula was equivalent to that of a normal shoulder in complete elevation. The current case provided an extremely rare clinical setting where shoulder mobility depended only on glenohumeral motion as a result of the complete loss of scapulothoracic motion.

[Reactive arthritis following Chlamydia infection].

The authors report on the clinical observation of 23 patients (5 women, 18 men) who suffered from seronegative spondylarthritis following chlamydia infection diagnosed clinically and serologically. Nine patients (2 women, 7 men) carried HLA B27 histocompatibility antigen. Sacroileitis confirmed by radiology was found in 16 cases. Genicular synovitis was the most frequent peripheral articular syndrome as well as Achilles tendinitis, "sausage-like" swelling of the finger and toes were observed and the ankle-, wrist-, elbow- and in a few cases the sternoclavicular and temporomandibular joint showed also involvement. Urological inflammation occurred in 9 cases, ophthalmological inflammation in 3 cases and pleuritis, pericarditis was observed in 1 patient. During the observation period 15 patients recovered upon Doxycyclin (Chinoin), Eryc (Biogal) non-steroid and occasional steroid therapy given 3 weeks long.

The timing of ossification of the limb bones, and growth rates of various long bones of the fore and hind limbs of the prenatal and early postnatal laboratory mouse.

In order to study the pattern of ossification of the skeletal components of the fore and hind limb of the mouse, intact embryos were isolated between days (d) 15 and 19 of pregnancy (the morning of finding a vaginal plug is termed d 1 of pregnancy), and postnatal animals isolated on d 1 (newborns), 7 and 14 after birth. The total number of fore and hind limbs studied for each day of pregnancy or postnatal day for the bone growth study is given in parentheses: d 15 (2), d 16, 17, 18 and 19 of pregnancy (5 specimens for each of these days), d 1 (newborn), wk 1 and 2, postnatal (4 specimens analysed at each of these times), since only the right limbs were studied. For the study involving the time of first appearance of ossification centres, either the right or the left limb of each of these prenatal and postnatal specimens was analysed. All specimens were fixed in 80% ethanol, bulk-stained using alizarin and Alcian blue, in order to stain ossification centres and cartilage, respectively, and cleared. The limbs were then disarticulated from the axial skeleton at the sternoclavicular and sacroiliac joints to facilitate (1) the determination of the sequential pattern of ossification in the various cartilage primordia analysed, and (2) the analysis of the pattern of growth of the humerus, ulna, femur and tibia. The latter values were plotted graphically, and the individual growth rate of each of the long bones studied was then deduced and also plotted graphically. The findings demonstrated that, with the exception of the femur and ulna, all of the long bones studied had significantly different growth patterns. The time of appearance of the various centres of ossification in the skeletal elements studied proceeded in a similar order to that described by previous authors, though there was some discrepancy in the exact time of first appearance of certain ossification centres. Of particular interest was the somewhat unusual pattern of ossification of the first digits of both the fore and hind limb compared with that of the other digits. The data presented here provide useful baseline information on the normal sequential pattern of ossification in the fore and hind limb, and the characteristic growth pattern of the individual long bones of the limbs in this species.

Sports injuries of the shoulder.

Much strain is placed on the shoulder joint in all sports. Sports injuries may be caused by a single, violent incident. Fractures of the clavicle, acromioclavicular and sternoclavicular traumas, isolated fractures of the greater tuberosity and shoulder dislocations are frequent clinical pictures which today can be managed by well established procedures. Other sports injuries, however, involve over-use of the shoulder which, through repetitive harmful movements, can bring about microtraumatic lesions of the rotator cuff, glenoid labrum, acromioclavicular joint and certain peripheral nerves around the suprascapularis. In all cases, a programmed, comparative, clinical examination and complementary, sequential examinations will indicate suitable curative and preventive treatment.

Posterior sternoclavicular dislocations: a review of management and complications.

Posterior sternoclavicular dislocations are relatively uncommon injuries. Nevertheless, these dislocations are associated with potentially fatal injuries to the mediastinum and the great vessels. Medial clavicle physeal injury with posterior dislocation may present with a similar clinical picture in younger patients. There is a wide variety of techniques for managing these injuries. In this article, we review recent techniques for reducing and managing posterior sternoclavicular dislocations.

[Treatment of anterior sternoclavicular dislocations. Apropos of 18 cases].

Eighteen cases of subluxation or dislocation of the sterno clavicular joint are reported. Six subluxations have been treated conservatively with prompt and good recovery. Out of twelve dislocations, three have not been operated on : two have recovered satisfactorily, after wiring and capsular suture (two recent cases) and after wiring and ligamentoplasty with palmaris longus (two old cases). But capsular suture and wiring gave only a fair result in one case of recurring dislocation, while tenodesis after Jackson Burrows gave excellent results in three cases. In recent cases, open reduction with wiring and capsular suture is advised, and tenodesis with subclavius, every time capsular suture is unsatisfactory and in all ancient and recurring cases, when troublesome.

Medial clavicular epiphysiolysis in children: the so-called sterno-clavicular dislocation.

We retrospectively reviewed six pediatric cases of medial clavicular injury, i.e., epiphyseal separation (Salter/Harris type I or II injury), diagnosed between 1993 and 1997. The clavicular metaphysis was displaced posteriorly in three cases and anteriorly in three. On conventional radiographic views the diagnosis was initially missed in two of three retrosternal dislocations. A special X-ray projection (described by Heinig) or computed tomography (CT) permitted correct diagnosis. Anterior dislocations were immediately and correctly diagnosed. Closed reduction successfully treated retrosternal displacement in two of the three patients. The third patient needed open reduction and internal fixation. Open reduction and internal fixation had to be performed in all three patients with anterior displacement. Follow-up assessment showed perfect functional results in all cases. Direct visualization during open reduction, which was necessary in four of six cases, yielded clear evidence that the so-called sternoclavicular dislocation in children and young adults is, in fact, a fracture of the medial growth plate with posterior or anterior displacement of the metaphysis.
