Evaluation of Labral Pathology and Hip Articular Cartilage in Patients with Femoroacetabular Impingement (FAI): Comparison of Multidetector CT Arthrography and MR Arthrography.

Summary Background To compare the multidetector computed tomography (MDCT) arthrography (CTa) and magnetic resonance (MR) arthrography (MRa) findings with surgical findings in patients with femoroacetabular impingement (FAI) and to evaluate the diagnostic performance of these methods. Material/Methods Labral pathology and articular cartilage were prospectively evaluated with MRa and CTa in 14 hips of 14 patients. The findings were evaluated by two musculoskeletal radiologists with 10 and 20 years of experience, respectively. Sensitivity, specificity, accuracy, and positive predictive value were determined using surgical findings as the standard of reference. Results While the disagreement between observers was recorded in two cases of labral tearing with MRa, there was a complete consensus with CTa. Disagreement between observers was found in four cases of femoral cartilage loss with both MRa and CTa. Disagreement was also recorded in only one case of acetabular cartilage loss with both methods. The percent sensitivity, specificity, and accuracy for correctly assessing the labral tearing were as follows for MRa/CTa, respectively: 100/100, 50/100, 86/100 (p<0.05). The same values for acetabular cartilage assessment were 89/56, 40/60, 71/71 (p>0.05) and for femoral cartilage assessment were 100/75, 90/70, 86/71 (p>0.05). Inter-observer reliability value showed excellent agreement for labral tearing with CTa (κ=1.0). Inter-observer agreement was substantial to excellent with regard to acetabular cartilage assessment with MRa and CTa (κ=0.76 for MRa and κ=0.86 for CTa) Conclusions Inter-observer reliability with CTa is excellent for labral tearing assessment. CTa seems to have an equal sensitivity and a higher specificity than MRa for the detection of labral pathology. MRa is better, but not statistically significantly, in demonstrating acetabular and femoral cartilage pathology.

Open Humerus Shaft Fracture With Ipsilateral Anterior Shoulder Fracture-Dislocation and Posterior Elbow Dislocation : A Case Report

Fracture of the shaft of the humerus or femur associated with the dislocation of the adjacent proximal or distal joints is a rare but serious injury in adults. The magnitude of the force required is greater in the lower limb than that in the upper limb. Humerus shaft fracture associated with anterior or posterior dislocation of the shoulder joint is an uncommon injury and 20 cases have been reported in the literature since 1940. Humerus shaft fracture associated with an elbow dislocation is an extremely rare injury and ipsilateral forearm fracture has also been coexisting in all three cases reported in the literature. Besides these, three cases with ipsilateral shoulder and elbow dislocations without a humerus shaft fracture have been reported in the literature. Nevertheless, simultaneous humerus shaft fracture with ipsilateral both shoulder and elbow dislocations is an extraordinary injury and to our knowledge, such an injury has not been previously reported in the literature. The aim of this study is to report such a case and to discuss its management and possible complications. The patient was informed that data concerning this case would be submitted for publication.

Percutaneous release for trigger thumbs in children: improvements of the technique and results of 31 thumbs.

Purpose Trigger thumb is a relatively uncommon condition in children. If it occurs or persists after 1 year of age, surgical release is the most traditional treatment method. The aim of this prospective study is to describe a technique for the percutaneous release of trigger thumb and to assess the clinical outcome of the presented technique in the pediatric age group. Methods This study includes 31 thumbs of 26 consecutive children with a mean age of 2.6 years. An 18-gauge needle that was connected to 10-cc saline filled syringe was used as the surgical instrument for release. Contrary to the earlier reports, the A1pulley was cut from distal pole of the Notta nodule towards the proximal direction. Results Mean follow-up period was 2.5 years. A successful release without any complication was obtained in all (97% of thumbs) but 1 thumb. Recurrence was seen in only 1 thumb at postoperative 3 weeks. Conclusion The presented minimal invasive surgical procedure has a high rate of satisfactory outcome, a minimal rate of complications, and a high rate of parent satisfaction. As percutaneous release has satisfactory and encouraging results, it can be a preferred method by the parents for trigger thumb release. Study Level III.

Mazabraud's Syndrome Coexisting with a Uterine Tumor Resembling an Ovarian Sex Cord Tumor (UTROSCT): a Case Report

The association of intramuscular myxoma and fibrous dysplasia is a rare disease known as Mazabrauds syndrome. We present a case of Mazabrauds syndrome coexisting with a uterine tumor and resembling an ovarian sex cord tumor (UTROSCT). This uterine tumor showed a high mitotic index and cytological atypia. To the best of our knowledge, the coexistence of the two different entities has not been reported in the literature.

Assessment of the use of hip ultrasonography by Graf's method between 1 and 6 years of age.

Ultrasonographic examinations of both hips of 133 children whose age ranged from 13 to 72 months were performed using the Grafs method. A standard plane which was mandatory prior to the hip typing could be obtained in 93, 91, 84, 79 and 66% of the sonograms for 13–24, 25–36, 37–48, 49–60 and 61–72 months age groups, respectively. The 61–72 months age group had the lowest percentage of valid sonograms and this difference was considered significant (P=0.001). It was concluded that plain radiography was still the gold standard imaging technique in developmental dysplasia of the hip, but hip ultrasonography by the Grafs method might be an alternative imaging technique in experienced hands for the evaluation of developmental dysplasia of the hip in children between 1 and 5 years of age.

Magnetic resonance imaging of bilateral lateral congenital dislocations of unossified patellae

We describe our experience using magnetic resonance imaging (MRI) to evaluate the unossified dislocated cartilaginous patella in a 6-year-old male patient with restricted extension and flexion deformity of both knees. MRI is used widely in the visualization of cartilage since it can show cartilage directly. In addition, FS FLASH 3D sequence has recently been accepted as a suitable sequence in the evaluation of hyaline cartilage. MRI makes it possible to evaluate ligamentous, tendinous, muscular, and cartilaginous structures as well as the abnormalities related to them. We applied this technique in our case and found it very effective in locating the unossified dislocated cartilaginous patella. We also observed structural changes such as bilateral lateral displacement of short quadriceps tendon inserting into diminutive patella, insertion of bilateral patellar tendons into anterolateral tibia, and a stretching of the medial collateral ligament associated with valgus stress.

Incomplete left-hand and complete right-hand pisiform and hamate coalition: multidetector computed tomography findings.

Pisiform-hamate coalition is a rare form of carpal coalition. Only 14 cases of pisiform-hamate coalition have been reported in the English-language literature. We present a case of asymptomatic bilateral pisiform-hamate coalition in a 16-year-old boy. We also review the embryology, pathogenesis, and clinical features of pisiform and hamate coalition, along with the associated multidetector computed tomography findings.

Preoperative hematological assessment of pediatric patients

OBJECTIVES Nutritional deficiencies and use of antiepileptic drugs can lead to alterations in the hematological status of children with cerebral palsy (CP), which may increase the risk of intraoperative or postoperative hematological complications. In this retrospective study, we evaluated the preoperative routine blood tests of CP patients with different levels of walking ability, who were scheduled to undergo orthopedic procedures. METHODS Hemoglobin level, hematocrit, red blood cell count, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, red cell distribution width, white blood cell count, platelet count, prothrombin time, activated partial thromboplastin time, and plasma fibrinogen concentration were compared between 62 consecutive CP patients [28 girls, 34 boys; mean age 8.8 years (range 2-16 years)] and 130 consecutive orthopedic patients as control [64 girls, 66 boys; mean age 9.2 years (range 2-16 years)] who did not have any skeletal, cranial, thoracic, abdominal or major soft tissue injuries, or any other infectious, metabolic, hematological or malignant tumor disorders. RESULTS CP and control groups were similar with regard to the above-mentioned hematological parameters. In the CP group, no difference was found between Gross Motor Function Classification System for Cerebral Palsy (GMFCS) level I/II patients and GMFCS level III/IV patients in terms of these hematological parameters. CONCLUSION Preoperative blood tests results of pediatric CP patients, walking with or without any supportive devices and undergoing orthopedic interventions, are similar to those of other orthopedic patients. Advanced preoperative hematological tests can only be recommended for CP patients with abnormal blood test results.

Pulled elbow in children: a case series including 66 patients.

The aim of this case series was to assess the data of 66 children (mean age 28 months) with a diagnosis of pulled elbow. The most common time interval of injury was 12–6 p.m. and spring was the peak season. Children younger than 2 years of age had a higher rate of atypical injury history. A successful reduction by supination and flexion maneuver was achieved at the first attempt in 57 of 66 patients. The patients admitted to the hospital within the first 2 h following the injury had a higher rate of successful reduction at the first attempt. The rate of radiographic examination was considerably high and a well-defined algorithm to avoid the complicacy in ordering a plain radiograph in such cases was suggested. All patients achieved full clinical recovery after a mean follow-up of 2 years, and recurrence was observed in 16 of 66 children.
