Cervical rib--preliminary data on diagnosis by ultrasound.

AIM: To determine whether ultrasound is useful in detecting cervical rib. Ultrasound was used to diagnose cervical rib in five patients with neck pain and the findings were compared to those from plain radiography. MATERIALS AND METHODS: Ultrasound was used in 34 patients with pain and stiffness in the neck region. The area concerned was scanned sonographically in both longitudinal and transverse planes. In the sitting position, plain radiographs were obtained after ultrasound examination for comparison and verification. The contralateral side of the neck was used as control. RESULTS: Sonography revealed abnormalities in five patients. Sonography and X-ray confirmed the diagnosis of cervical rib in six patients, whereas one patient had a lipoma of the neck. CONCLUSION: Sonography is an additional and easily available diagnostic modality for the detection of cervical rib in cases of pain and stiffness in the neck region.

Ultrasonographic findings in patients with olecranon bursitis.

BACKGROUND: Musculoskeletal ultrasonography (U.S.) is an important imaging technique in the diagnosis of olecranon bursitis, especially for early manifestation. It allows sensitive detection of small fluid collections as well as for differentiation between soft tissue and bone lesions. U.S. examination allows detection of effusions, synovial proliferation, calcifications, loose bodies, rheumatoid nodules, gout tophi and septic processes. AIM: To assess the role of ultrasonography in the diagnosis and management of patients with olecranon bursitis. METHODS: Ultrasound was used in 34 patients with swelling above the olecranon. The opposite asymptomatic side served as a control group. RESULTS: 20 patients demonstrated increased fluid collection in the olecranon bursa. 5 had synovial proliferation, 2 cases showed loose body, 5 patients revealed markedly increased blood flow consistent with inflammation, 2 patients had triceps tendonitis with calcifications. CONCLUSIONS: Sonography is an extremely effective tool for the diagnosis of soft tissue lesions in the olecranon area.

Sonographic imaging of mallet finger.

UNLABELLED: Mallet finger is a flexion deformity of the distal interphalangeal joint (DIPJ) caused by a disruption of the extensor mechanism. The deformity can b e caused by active trauma, minor trauma or other conditions like rheumatoid arthritis or osteoarthritis. AIM: To describe the sonographic findings in mallet finger. METHOD: We performed sonographic examination on thirty patients with traumatic mallet finger, on thirty control patients where we examined the same finger in the opposite hand (,) and thirty patients with rheumatoid arthritis or osteoarthritis and flexion deformity. RESULTS: We found four criteria for traumatic mallet finger which included: discontinuity of the extensor tendon with partial or complete tear, avulsion fracture, no real time movements of the extensor tendon, and fluid in the region of insertion of the extensor tendon. CONCLUSION: Sonographic examination of patients with traumatic mallet finger is an important diagnostic tool and can differentiate between traumatic mallet finger and flexion deformity of rheumatoid arthritis or osteoarthritis.

Total hip arthroplasty in patients younger than 30 years of age following developmental dysplasia of hip (DDH) in infancy.

Total hip arthroplasty (THA) in young patients is a controversial subject, due to the high failure rates reported in the literature, and even more so in patients with a history of developmental dysplasia of the hip (DDH). A group of 11 patients, all under the age of 30 years at the time of surgery, underwent THA due to congenital dislocation of the hip. Mean age at the time of operation was 23.3 years (range 16-30 years). The mean follow-up period was 9 years (range 3-14 years). The mean preoperative Harris' hip score (HHS) was 56.9 compared with the postoperative HHS of 90.6. Due to aseptic loosening of the cup, 4 patients underwent successful revision arthroplasty. These encouraging medium-term results in our patients suggest that THA may be a good solution for young patients suffering from coxarthrosis due to DDH, at least temporarily, especially when other alternatives, such as arthrodesis or resection arthroplasty, are considered.

Ultrasonography: an imaging modality enabling the diagnosis of bipartite patella.

Ultrasound was used to diagnose bipartite patella in seven adolescents with anterior knee pain, and the findings were compared to those from plain radiography and to those of a group of asymptomatic subjects. In all affected individuals the quadriceps and patellar tendons appeared normal on ultrasound. Sonographic examination of the patella demonstrated an irregularity of the bony contour with occurrence of a cleft between the main part of the patellar body and the large superolateral accessory ossicle. The signal detected in the interface between bones was less echogenic than bone reflecting its fibrocartilaginous nature. The correlation with conventional radiography was absolute, as was the inter- and intraobserver reliability. Ultrasound is thus proposed as a simple and reliable imaging modality in bipartite patella. We do not believe that it should replace the initial radiographic, but it can be used to evaluate the contralateral knee for bilaterality and as an adjunct to therapeutic procedures such as local injections to increase the accuracy of treatment.

Ultrasonography as a diagnostic modality in Osgood-Schlatter disease. A clinical study and review of the literature.

Sonographic examination of the knee has been proposed by several authors in the past as a simple and reliable method to diagnose Osgood-Schlatter disease (OSD). Ultrasound was used to compare the knees of 25 boys and 10 girls with typical OSD with 35 symptom-free knees of an aged-matched group of children. Based on recorded data, patients were categorized (one affected knee in each individual) according to the classification system proposed by De Flaviis et al. in 1989. The results included the following pathological findings: pretibial swelling, fragmentation of the ossification center, insertional thickening of the patellar tendon, and excessive fluid collection in the infrapatellar bursa. Of our patients, 26% fell into the type 1 category, 43% were type 2, 20% type 3, and 11% type 4. This distribution of cases was found to be statistically similar to the initial findings reported by De Flaviis and colleagues. This study therefore supports the validity and reproducibility of their classification method for the ultrasonographic evaluation of children with OSD. This is only the first step, and further assessment of this classification is still required to elucidate its clinical as well as its prognostic value.

Achilles tendon pain and related pathologies: diagnosis by ultrasonography.

BACKGROUND: When encountering complaints of pain in the area of the Achilles tendon, the clinician seldom reaches a correct and precise diagnosis based solely on the grounds of physical examination and standard X-rays. OBJECTIVES: To assess the usefulness of ultrasound in diagnosing pathologies of the Achilles tendon. METHODS: We conducted a retrospective review of patients presenting at our orthopedic clinics. RESULTS: Sonography was used to evaluate 41 patients with achillodynia. This modality enabled the diagnoses of 19 abnormal tendons (46%), peritendinous and other lesions; a complete rupture in two patients (5%); a partial rupture of the Achilles tendon in 3 (7%); various degrees of calcification of the tendon in 7 (17%); and peritendinous lesions discerned by the tendon's hypoechoic regions with disorganized arrangement of collagen fibrils in 4 patients (10%). Other lesions included tendonitis (3 patients, 7%), retrocalcaneal bursitis (3 patients, 7%), lipoma (1 patient, 2%), and foreign bodies (2 patients, 5%). The mean diameter of the pathological tendons was 10.4 +/- 2.7 mm, while normal tendons measured 5.2 +/- 0.8 mm (P < 0.001). CONCLUSION: As in many other soft tissue lesions, ultrasonography is a useful tool in the evaluation of the underlying pathology in patients presenting with achillodynia.

Prenatal diagnosis of distal arthrogryposis type 1.

A 23-year-old woman, gravida 1 parity 0, was referred for routine ultrasound examination at 23 weeks gestation. Fetal anatomy was normal. However, both hands demonstrated clasped thumbs without extension. Repeated ultrasound examination verified the bilateral hands posture. The position of the hands did not change following sound stimulation. The child was diagnosed as distal arthrogryposis type 1. Prenatal counselling by the pediatric orthopedic surgeon, geneticist and gynecologist, was provided, to inform the parents on the probable outcome of the fetus and the hands. The parents were advised to continue with the pregnancy. A 1,975-g healthy boy was delivered by spontaneous vaginal delivery. Neonatal examination confirmed the prenatal diagnosis of arthrogryposis type 1. Following reconstructive surgery the child functions well with both his hands.

[Acquired torticollis in hospitalized children].

Torticollis results from various pathological mechanisms, and its elucidation depends on identifying diseases of musculoskeletal, neural and ocular tissues. This study characterized the underlying diseases of children hospitalized with torticollis, excluding congenital torticollis. Records of 36 children with torticollis seen during 4 years were reviewed and categorized according to presumed etiology. Most could be classified into 2 categories: in 39% it was due to trauma and in 36% to upper respiratory tract infection. Most girls were in the first group and most boys in the second group. There were 3 cases of ocular torticollis due to superior-oblique muscle palsy, 1 with a post-burn eschar, 2 with neurological disorders (intramedullary cervical astrocytoma and leukodystrophy with macrencephaly), and in 3 no associated cause was found. There was a clear seasonal trend with 58% of cases presenting from November through February, 33% from April through July, and the rest, of neurological or ocular origin, during the rest of the year. In cases of post-traumatic torticollis 21% had neurological symptoms such as weakness of the limbs, headaches or incontinence. Only a few had prior upper respiratory tract infection. All children whose torticollis was assigned to infection had had fever. Only 8% had had neurological complaints or vomiting, half of whom presented with fever exceeding 37.5 degrees C. 46% had restriction of movement and 38% had tenderness. In over 60% of those in this group there were signs of an upper respiratory tract infection, such as lymphadenopathy or a white blood cell count exceeding 15,000/microliter, 3 patients with recurrent torticollis were diagnosed as having severe neurological diseases. Mean hospitalization time was 4 days (range 1-28). Hospitalization periods were similar for all kinds of patients and treatment by traction or fixation did not affect this period.

[Leg-lengthening for length inequality].

32 patients (age range 1.5-22 years) were treated for leg-length discrepancy. 39 lengthening procedures were performed of which 36 involved gradual distraction, in 2 cases chondrodiasthesis was used, and 1 had 1-step elongation. Gradual distraction was done according to Ilizarov, including corticotomy and a 1-week delay before the initiation of distraction. In 33 cases Wagner's external fixator was used, in 2 Ilizarov frame and in 1 an orthofix fixator. There was complete clinical and radiologic union in all but 1 case. Significant correction of leg-length discrepancy and equalization of leg-length was achieved in most patients. In some growing patients over-correction was successfully achieved. The most prevalent complications were pin-site problems, axis deviation, joint subluxation and joint contractures. At latest follow-up most of these complications had disappeared. 91% of the patients either functioned normal or were only mildly limited.

Fresh osteochondral allografts at the knee joint: good functional results in a follow-up study of more than 15 years.

The treatment of deep chondral defects at the knee joint poses major difficulties and challenges to the orthopaedic surgeon, particularly in young patients for whom solutions like total or hemi-joint arthroplasty are not recommended, because of their limited durability. Biological resurfacing with materials such as perichondrium, periosteal allografts, and cultured chondrocytes is still at the experimental stage and there has been limited clinical validation. Since 1978, we have successfully used fresh osteochondral ('shell') allografts for the treatment of selected patients with a chondral defect at the knee joint. These grafts, implanted mainly in young patients, have proved durable and have provided good functional results for more than 15 years, as shown by an average of 84.6 in the Hospital for Special Surgery (HSS) Knee Score. The operative technique and results of long-term follow-up of patients receiving fresh, osteochondral ('shell') allografts are presented and discussed.

Effect of proximal phalangeal epiphysiodesis in the treatment of macrodactyly.

The recommended treatment for macrodactyly of the foot will often include epiphysiodesis of the proximal phalanx in an attempt to halt further longitudinal growth of the toe. Nine patients who underwent open epiphysiodesis and debulking of the excess soft tissues involving 11 toes were reviewed to evaluate the effectiveness of this procedure. In 9 of 11 toes, overall length of the proximal phalanx did not change after surgery. Two toes demonstrated continued growth; one of these toes underwent a repeat epiphysiodesis of the phalanx, and the other foot underwent epiphysiodesis of the affected metatarsal. Overall, this surgical approach led to radiographic results that satisfied the surgical goals.
