Ultrasonography and clinical examination of knee injuries in pre- and post- menarche dancers.

This study aimed at evaluating whether the prevalence of knee injuries and morphological features are different among pre-and-post menarche dancers; Sixty-seven pre-and-post menarche dancers were screened for anthropometric parameters; knee laxity; patella femoral pain syndrome (PFPS), pathologies and anatomical structure of the knees. Both groups showed a high and similar prevalence of PFPS. The post-menarche dancers produced a significantly higher rate of Tanner stages 3-4 (p = .010), greater weight (p < .001) higher BMI (p = .003); and, higher prevalence of MCL pathology, pes planus, and scoliosis compared with pre-menarche dancers (p < .05). The pre-menarche dancers started dance practice earlier (p = .008); and, showed significantly higher prevalence of lateral laxity, patellar laxity, positive Lachman test and positive Drawer test compared with post-menarche dancers (p < .05). Interactions (menarche yes/no by PFPS no/one leg/both legs) were found for BMI (p = .044; η2 = .187), trochlear cartilage thickness (p = .020; η2 = 0.121) and tip of patella - trochlear groove distance (p = .024; η2 = .150). Pre-and-post-menarche female dancers demonstrated similar prevalence of knee injuries, with different body morphology.

Ultrasonography findings and physical examination outcomes in dancers with and without patellofemoral pain.

OBJECTIVES: To identify whether a physical examination for patello-femoral pain (PFP) is related to ultrasonography findings at the knee, and to identify possible factors related to PFP in young dancers. METHODS: Sixty-seven young female dancers (7th grade, aged 12.8 ± 0.5) from three schools with identical special dance programs were included in the study. All the dancers were interviewed for demographic details, dance background, and training intensity; were evaluated for anthropometric measurements; underwent physical examination of both knees for PFP and for knee range of motion (ROM); and, had ultrasonography assessment for pathologies and of anatomical parts of their knees. RESULTS: PFP was found in 54.5% of the 134 knees physically examined. In ultrasonography assessment, infra-articular effusion was found in 46.2% of the knees examined. H/week of dance practice was significantly higher among dancers with PFP (in both knees) compared with dancers with no PFP (p < .05). Knees with PFP had a significantly higher prevalence of intra articular effusion (p = .018) and higher prevalence of genu-recurvatum (p = .042). Knees with PFP had significantly greater growth plate width-anterior tibial tuberosity (p = .022) and a greater bony trochlear groove angle (p = .048). CONCLUSION: This study describes the relationship between physical examination for PFP and the sonographic findings, and the factors related to knee injuries. The results showed a high prevalence of PFP and intra articular knee effusion among young dancers at the age of 12-13 years; and, that the number of hours of practice and anatomical structure are related to PFP. Our results should alert physicians, physiotherapists, athletic trainers and dance teachers to the need for devising modifications of training and injury prevention strategies from a young age (<12 years old).

Ultrasound in the diagnosis of clinical orthopedics: The orthopedic stethoscope.

Ultrasonography has advantages over other imaging modalities in terms of availability and comfort, safety, and diagnostic potential. Operating costs are low compared with both computed tomography (CT) and magnetic resonance imaging (MRI). The portable equipment is accessible at locations distant from medical centers. Importantly, ultrasonography is performed while patients lie in a comfortable position, without pain or claustrophobia.

Lumbar disk replacement with the ProDisc prosthesis.

Twenty-two ProDisc II prostheses (Spine Solutions, New York, New York) were implanted in 21 patients with degenerative disk disease at L5-S1 (19 disks) and L4-L5 (3 disks). After mean follow-up of 3.1 years (range, 17-49 months), pain intensity in all but 3 patients had improved from an average of 7.7 preoperatively to 4.6 postoperatively (P< .001) on a visual analog scale. Average Oswestry Disability Index score improved from 61 to 35 (P< .001). Radiographic reconstruction of the disk space height was achieved in all cases. Previous diskectomy at the implanted level and disk degeneration adjacent to previous fusion negatively influenced the results.

Percutaneous Achilles tendon repair combined with real-time sonography.

BACKGROUND: When encountering complaints of pain in the area of Achilles tendon with a suspected lesion, the clinician seldom reaches a precise diagnosis based only on X-ray and clinical examination. Ultrasonography is useful for evaluating the pathology and treatment. OBJECTIVES: To assess the relative contribution of real-time intraoperative ultrasound examination and immediate postoperative ultrasound in patients with acute rupture of the Achilles tendon treated by percutaneous suture method. The combination of both procedures provides a unique advantage that could facilitate better results. METHODS: Ultrasound examination was used in 20 patients with acute rupture of the Achilles tendon who were treated surgically. Intraoperative as well as postoperative ultrasound examinations were performed in 5 patients while 15 patients underwent an immediate postoperative ultrasound. RESULTS: Ultrasound pathologies were found in all patients. Percutaneous surgical correction of ruptured Achilles tendon with accurate positioning of the foot using real-time sonography was successful in all the patients. CONCLUSION: As in many other soft tissue lesions, ultrasonography is a useful tool for evaluating the pathology and for planning the surgical correction of ruptures in the Achilles tendon.

Treatment of femoral fractures in neonates.

BACKGROUND: Fractures of the femur in neonates are relatively uncommon. The infants feel pain and discomfort, causing parental distress, and the hospital stay is longer. Treatment of this specific fracture is problematic because of the small size of the baby. OBJECTIVES: To review the results of the treatment of neonatal femoral fractures. METHODS: We retrospectively reviewed all neonatal fractures of the femur during a 12 year period. Thirteen fractures of the femur in 11 babies were treated with improvised Bryant skin traction of both legs. All the patients were reexamined after a mean follow-up period of 5.2 years. RESULTS: All fractures healed satisfactorily clinically and radiographically, with no residual deformity, leg length discrepancy or functional impairment. CONCLUSIONS: Bryant's traction for 2-3 weeks in hospital is a safe method for the treatment of femoral fractures in neonates, and the outcome is good.

Intradiscal cement leak following percutaneous vertebroplasty.

STUDY DESIGN: A retrospective study to detect patients with cement leakage into the disc space following vertebroplasty. OBJECTIVE: To determine the frequency, causes, and clinical significance of cement leakage into the disc space. SUMMARY OF BACKGROUND DATA: Much has been written about cement leakage into the epidural space following vertebroplasty but only little about intradiscal leakage. METHODS: A total of 66 patients with 1 cemented osteoporotic, fractured vertebra between T5 and L5 were followed for at least 2 years. Two of the senior authors (Y.M. and A.P.) evaluated independently cement leakage into the disc space, possible causes were investigated, and the clinical results were evaluated according to patient self-assessment. RESULTS: Detected in 27 patients, cement leakage into the disc space did not negatively affect patient satisfaction with the procedure. In 7 of these patients, leakage occurred through an intravertebral vacuum cleft and, in 8, through a perforation of the endplate created by the needle tip. In only 2 patients was cement found to cross the height of the vertebral body and leak into the contralateral disc. CONCLUSIONS: Apart from iatrogenic endplate perforation, cement extravasation into the disc space was always found to occur through the fractured endplate or a vacuum cleft. Placing the needle tip far from the fractured endplate and using more solid cement appear to decrease the risk of leakage.

Postural control in patients with severe idiopathic scoliosis: a prospective study.

Thirty-one patients with severe adolescent idiopathic scoliosis were evaluated preoperatively by computerized dynamic posturography. Curve type, magnitude and spine balance were measured radiographically. In four girls, a very mild vestibular dysfunction was observed on the sensory organization analysis, and three of them had a horizontal shift of more than 2 cm; a disbalance was observed in only three other patients among the 27 patients with normal posturography. These results suggest that abnormalities in the sensory systems are not involved in the etiology of severe adolescent idiopathic scoliosis. The vestibular dysfunction detected in the four patients was most probably the result of disbalance and not the cause of the disease.

Complete paraplegia following gunshot injury without direct trauma to the cord.

STUDY DESIGN: A retrospective review of all patients with neurologic deficit following gunshot wounds that did not penetrate the spinal canal. OBJECTIVES: To evaluate the possibility that neurologic deficit following gunshot wounds is possible without direct trauma to the cord. SUMMARY OF BACKGROUND DATA: Gunshot injuries to the spine account for 13% to 17% of all spinal cord injuries and are likely to result in complete paraplegia. Neurologic deficit is the result of direct trauma to the nervous tissue by the bullet, bone, or disc fragments, which compress the cord. METHODS: The medical charts, radiographs, CT scans, and myelographies or MRIs of all patients admitted to our hospital with neurologic deficit secondary to gunshot wounds between 1977 and 2003 were reviewed. Twenty-six patients were identified: 15 with complete and 11 with incomplete paraplegia. In 19 patients, the spinal canal at the level of injury was explored and decompressed. RESULTS: In 3 patients with complete paraplegia at the thoracic level, CT scan, myelography (1 patient), MRI (2 patients), and operative exploration (2 patients) did not indicate any signs of canal compromise. Two were injured by low-velocity bullets passing through the vertebra (in 1 patient) and the posterior part of the lamina (in the second). The third was injured by high-velocity bullets with no signs on MRI of any injury to the vertebral column or spinal cord. At follow-up 4.1 years later, on average, none had any neurologic recovery. CONCLUSION: Neurologic deficit following gunshot wounds is possible even without violation of the spinal canal. It is most probably the result of the kinetic energy emitted by the bullet.

Congenital muscular torticollis in infants: ultrasound-assisted diagnosis and evaluation.

Ultrasonography is considered the modality of choice for differentiating congenital muscular torticollis from other pathologies in the neck. The authors present their experience with ultrasound examination for the evaluation and management of congenital muscular torticollis. Twenty-six infants, 14 boys and 12 girls, age ranging from 1 to 16 weeks, with torticollis and a palpable mass were examined. Ultrasound showed a well-defined mass in the sternocleidomastoid muscle. The lesions ranged in size from 8 to 15.8 mm on maximal transverse diameter, with length ranging from 13.7 to 45.8 mm. Clinically the torticollis disappeared between 1 to 6 weeks, with complete clinical reduction of the palpated mass between 2 and 8.5 weeks. The ultrasonographic disappearance of the mass was delayed by an average of 2 weeks in comparison to the clinical disappearance of the mass. Ultrasound is advocated for the diagnosis and follow-up of congenital muscular torticollis because it noninvasively provides reliable and dynamic information without sedation.

Five-year experience with the 'Sheba' model of comprehensive orthogeriatric care for elderly hip fracture patients.

BACKGROUND AND PURPOSE: The Sheba model of orthogerioatric medicine is a unique model of in-hospital care for elderly hip fractured patients, based upon the concept that a hip fracture represents a geriatric, rather than an orthopedic disease. The nature and feasibility of such a comprehensive orthogeriatric unit, taking care of all surgical, medical and rehabilitation needs, in a single geriatric-based setting (rather than orthopedic-based), were questioned. The aim of the study is to describe the results of its operation during a five-year period. METHOD: A retrospective charts analysis of consecutive older patients with hip fractures, admitted from the emergency unit directly to the orthogeriatric unit of a department of geriatric medicine. RESULTS: A total number of 592 patients were admitted. Mean age of patients was 83.2 years, mostly women. A total of 538 (91%) were treated surgically. Delay to surgery was 3.6 +/- 2.9 days. A total of 65.6% were suitable for rehabilitation, and had a mean Functional Independence Measure (FIM) gain of 22.3 +/- 7.9. Mean total hospital length of stay was 29.9 days and 68.7% of patients returned to their previous living residence. Rates of major complications (4.1%) and in-hospital mortality (3.2%, equivalent to 30 days mortality) were low. CONCLUSIONS: Treatment within this unit was associated with low rates of major morbidity and mortality, short stay and acceptable functional outcomes. The data provide clinical evidence supporting the implementation of this model of comprehensive orthogeriatric care, being a practical, applicable and feasible service for elderly hip fractured patients, and covering the various needs of these patients. The present model of organization could also help in skillful use of economic resources, facilitating effective treatment strategies.

Ultrasonography as a diagnostic modality in acromioclavicular joint pathologies.

BACKGROUND: Ultrasound is useful in detecting acromioclavicular pathologies in cases of trauma, inflammations and degenerative changes. OBJECTIVES: To describe the sonographic findings of acromioclavicular joint pathology in patients with anterior shoulder pain. METHODS: Sonographic examination of the ACJ was used to examine 30 adults with anterior shoulder pain. As a control group we studied 30 asymptomatic patients and compared the findings to plain radiographs of the symptomatic group. RESULTS: The pathologic findings consisted of swelling of the joints, bone irregularities, widening and/or narrowing of the ACJ, soft tissue cyst formation, excessive fluid collection, and calcification. All these signs represent degenerative changes compatible with early osteoarthritis. We encountered one case of septic arthritis that required joint aspiration and antibiotic treatment. CONCLUSIONS: It is our belief that ultrasonography should be used routinely in cases of anterior shoulder pain since it demonstrates various pathologies undetected by plain radiographs.

Treatment of septic arthritis of the hip joint by repeated ultrasound-guided aspirations.

Arthrotomy of the hip joint followed by a variable period of drainage or continuous irrigation and drainage is considered the accepted treatment of septic arthritis of the hip joint (SAHJ). The authors reviewed the results of a cohort of children with SAHJ with repeated aspirations of the hip joint. Thirty-four children diagnosed with SAHJ were treated with repeated aspirations of the hip joint. The aspirations were performed under ultrasound guidance and topical anesthesia or under sedation. After the aspiration the joint was irrigated using the same needle, and the procedure was repeated daily. Six of the patients were operated on and then treated with aspirations because of drain dislodgement or clogging. Twenty-eight of the patients were treated primarily with repeated aspirations. Four of those patients did not improve and underwent arthrotomies, and 24 were treated only by repeated aspirations and healed completely. The mean number of aspirations was 3.6 (range 3-5), and 75% of the patients resumed walking after 24 hours. The mean follow-up time was 7.4 years (range 3-18). No complications were seen. Repeated aspiration is a safe and efficacious method of treatment for SAHJ. This method of treatment is not associated with surgery and its complications and prevents scarring of the skin and the need for general anesthesia. Faster return to normal activity was noted in this series.

Dynamic footprints: adjuvant method for postoperative assessment of patients after calcaneal fractures.

BACKGROUND: Open reduction and internal fixation are the current trends of treatment for comminuted calcaneal fractures. Assessing treatment results is often difficult due to discrepancy between objective parameters such as range of movement, and subjective results such as pain. OBJECTIVES: To test the reliability of footprint analysis as an adjuvant method of postoperative assessment of patients who sustained calcaneal fractures. METHODS: Dynamic and static footprint analysis was used as an adjuvant additional method to objectively assess operative results. This method is simple and is independent of the patient's initiatives. This modality was used in 22 patients followed-up 9-90 months postoperatively. RESULTS: We found a good correlation between footprint analysis and objective and subjective parameters of results expressed by American Orthopedic Foot and Ankle Society hind foot score. In certain cases, this method can be used to distinguish between uncorrelated parameter results, such as malingering, and workmens' compensation claims. CONCLUSION: We recommend the use of this simple, non-invasive objective test as an additional method to assess the results of ankle and foot surgery treatment.
