The triceps brachii muscle and its insertion on the olecranon.

Background: The purpose of this anatomical study was to define the insertion of the tendon of the triceps brachii muscle and the course of the lateral cubital retinaculum (LCR) as an enhancement of the triceps tendon.

Material/methods: One hundred cadaver specimens were assessed and the widths of the triceps tendon and the olecranon and the expansion of the LCR were determined.

Results: The width of the tendon ranged between 1.

Fractures and dislocations of the foot in children.

The challenge of managing pediatric foot injuries is the identification of the rare injuries that require operative treatment and the management of complications such as compartment syndrome, post-traumatic foot deformities, and avascular necrosis. With these complications in mind, the authors discuss fractures of the talus, calcaneus, lesser tarsal bones, Lisfranc's joint, metarsals, and phalanges. Dislocation of metatarsophalangeal or interphalangeal joints is also discussed.

Sonoanatomy of the Achilles tendon insertion in children.

Purpose: The aim of this study was to describe typical age-related sonographic features of the Achilles tendon and calcaneal apophysis in children, providing a reference for the assessment of heel pathologies during the growth period.

Methods: The calcaneal apophysis and Achilles tendon insertion of 100 children 2 months to 18 years old were examined by high-frequency gray-scale and color Doppler sonography along both the longitudinal and transverse planes. The thicknesses of the apophyseal cartilage at the calcaneal tuberosity and of the Achilles tendon were measured.

[Posttraumatic AV fistula in the upper arm region following a foreign body injury. Sonographic diagnosis - a case report].

This paper reports on the sonographic localisation of a metallic foreign body in the upper arm region and its topographic anatomic position as well as the sonographic diagnosis of an AV fistula due to a lesion of the brachial blood vessels. Ultrasonography is the method of choice for the evaluation and diagnosis of foreign body injuries and possible subsequent complications.

Subluxation of the ulnar nerve in the elbow region--ultrasonographic evaluation.

Chronic ulnar nerve subluxation out of its sulcus in the elbow region may be a rare reason for undefined chronic disorders in the medial elbow aspect. We present two cases, a 38-year-old male patient complaining of a recurrent painful disorder including paresthesia of the 4th and 5th fingers and a 12-year-old boy presenting with a palpable band in the medial elbow region without pain. Ultrasonography was performed using a high frequency linear probe in the longitudinal and horizontal planes including dynamic examination.

[Ultrasound detection of dislocation of the ulnar nerve from the sulcus of the elbow joint].

Background: Chronic ulnar nerve subluxation out of the sulcus in the elbow region may be a rare reason for undefined chronic disorders in the medial elbow aspect.

Methods: We report two cases: A 38 years old male patient reports recurrent painful disorders including paresthesia of the 4th and 5th fingers. A 12 years old boy shows a palpable band in the medial elbow region without pain.

[Ipsilateral femoral fracture and anterior hip dislocation in a 15-year-old girl: case report].

Operative management of concomitant ipsilateral femur fracture and anterior hip dislocation has not been previously described in the literature. We report the case of a 15-years-old girl who was injured in a motorcycle accident and presented with a femoral shaft fracture and a concomitant ipsilateral anterior hip dislocation. Operative management consisted of an attempted closed reduction of the femoral fracture, which was unsuccessful; thus, an external fixator was temporarily applied.

The proximal femoral nail (PFN)--a minimal invasive treatment of unstable proximal femoral fractures: a prospective study of 55 patients with a follow-up of 15 months.

In 1996, the AO/ASIF developed the proximal femoral nail (PFN) as an intramedullary device for the treatment of unstable per-, intra- and subtrochanteric femoral fractures. In a prospective study, we treated 55 patients having proximal femoral fractures with the PFN from 1997 to 2000. In 34 patients, we achieved what was close to anatomic reduction of the main fracture fragments.

External fixation in trauma of the foot and ankle.

External fixation as a modality is a versatile and minimally invasive stabilization option that should not be forgotten even as new and specially designed implants for nearly each bone become more fashionable. As a temporary traction device, the external fixator can help condition the soft tissues and, if closed reduction was sufficient, it can stay in place for definitive treatment. The external fixator can be used as an intraoperative distraction device and as a helpful tool for reduction, which can stay in place as a temporary immobilization.

The anatomy of the joint as a risk factor for Lisfranc dislocation and fracture-dislocation. An anatomical and radiological case control study.

he anatomy of the mortise of the Lisfranc joint between the medial and lateral cuneiforms was studied in detail, with particular reference to features which may predispose to injury. In 33 consecutive patients with Lisfranc injuries we measured, from conventional radiographs, the medial depth of the mortise (A), the lateral depth (B) and the length of the second metatarsal (C). MRI was used to confirm the diagnosis.

[Ultrasound diagnosis in knee and foot trauma].

Subsequent to clinical and radiologic examination, ultrasonography is an important diagnostic method in knee and foot trauma, especially to assess pathologic conditions of the periarticular soft tissue. The main indications for ultrasonographic assessment of the knee region are fluid conglomerations, injuries of tendons, ligaments, and muscles, and vascular diagnosis. The indications for ultrasonography in the foot region are diagnosis of foreign bodies, dislocation of the peroneal tendons, lesions to the flexor and extensor tendons, and osseous capsular and ligamentous avulsions.

[Ultrasound diagnosis of the Achilles tendon].

Due to the superficial position of the Achilles tendon and the development of high-resolution probes with 7.5, 10, and more MHz, which allow the exact depiction of even very small structures, ultrasonography is the method of choice for the diagnosis of acute and chronic Achilles tendon disorders. Using sonography, both chronic achillodynia (disorders of the tendon itself, peritendinous tissue, bursa, and insertion of the tendon at the calcaneus) and ruptures of the Achilles tendon are exactly diagnosed.

[Ultrasound diagnosis in hip trauma].

The Question is: What are the indications for ultrasonography of the hip joint following trauma, except the investigation in children, and in which cases does ultrasonography provide a useful improvement within the diagnostic cascade? Considering the limitations in evaluation of boney structures and also soft tissues (due to anatomic topography) and if CT and MRI is not available, the moin indications are: Suspected soft tissue lesions (articular effusion, bursitis, muscle tears etc.) and vascular disorders (deep venous thromboses, vascular tears and occlusions). Both in preoperative planning and in postoperative follow up, ultrasonography provides useful information (e.

[Ultrasound diagnosis in shoulder trauma].

In cases of injuries to the shoulder region, ultrasonography is an ideal supplement to clinical and radiologic examination, including dynamic functional evaluation. The advantages of the method in children and adults are mainly the reduction of conventional radiographs and thus a minimum exposure to radiation. Despite the growing experience of clinicians and the development of high-resolution sonographic technology, primary conventional radiology cannot be dispensed with.

[Ultrasonography in trauma].

The aim of this paper is to report on the possibilities of ultrasonography of the musculoskeletal system following traumatic injuries. Subsequent to clinical and radiologic examination, ultrasonography is able to confirm the primary diagnosis by dynamic comparison with a minimal expenditure of time and costs. The size, extent, and anatomic topography of tissue lesions are depicted.

[Ultrasonic anatomy of pediatric joints].

The radiological work-up of joint injuries in young children can be very tedious due to the absent ossification of secondary ossification centers, which cannot be seen directly on plain X-ray images in this age group. Cartilaginous joint structures therefore cannot be distinguished from joint gaps using X-ray images in young children. High-resolution ultrasound scanning probes facilitate ultrasound studies of cartilaginous joint structures and growth plates in young children, thus providing a new and rewarding option for imaging of traumatic alterations of growing joints, especially in children whose secondary ossification centers have not yet undergone calcification processes.

[Ultrasonographic imaging of pneumarthrosis of the knee joint--case report and experimental cadaver study].

In case of penetrating injuries near to the knee joint showing only a small skin lesion and no damage to tendons and neuro-vascular structures, opening of the joint cavity has to be taken into consideration. Besides surgical revision of the penetration canal, radiological depiction of free intraarticular air may be useful. We report the cases of two patients, who suffered from intraarticular effusion and pain two, respectively three days after a penetrating injury.

Capsular attachment to the distal radius for extracapsular placement of pins.

The aim of this study was to evaluate the anatomy of the wrist joint capsule on the distal radius. As such the extent of the joint capsule and the limits of attachment in relation to the articular surface were determined. Furthermore, the study also determined whether there was any reflection of the capsule onto the distal radius.

[The distal radius and surrounding soft tissues--ultrasound anatomy and ultrasound pathology in the adult and child].

Background: The aim of the study was to evaluate the ultrasonographic anatomy of the distal forearm (i.e. distal radius and surrounding soft tissue) and the typical changes occurring during growth, in adults and children.

[Diagnostic value of conventional roentgen image, computerized and magnetic resonance tomography in acute sprains of the foot. A prospective clinical study].

In order to gain satisfying results in the treatment of acute hyperflexion trauma to the foot, it is absolutely necessary to achieve an exact primary diagnosis because injuries to the tarsometatarsal joint are frequently missed primarily. Aim of this prospective clinical study was to evaluate the diagnostic reliability of conventional radiography, CT and MRI compared to each other. 75 consecutive patients after hyperflexion trauma to the foot were included.

Sonographic evaluation of the normal hypothenar compartment musculature.

Purpose: We propose a standardized sonographic examination technique to evaluate the muscles of the hypothenar region and describe their normal sonographic appearance.

Methods: The hypothenar region was studied with sonography in 20 healthy volunteers using 5-12-MHz linear-array transducers. The assessment included dynamic testing.

[Ultrasound anatomy of the shoulder joint during the growth period].

Aim Of Study: It is the aim of this investigation to describe the normal ultrasonographical appearance of the glenohumeral joint in childhood.

Methods: Ultrasound investigation was performed in 20 healthy children aged between 6 weeks and 19 years (median: 6 years) using 12 MHz linear probes. A dynamic examination of both shoulders was carried out.

Primary ulnar head prosthesis for the treatment of an irreparable ulnar head fracture dislocation.

We report the case of an irreparable fracture - dislocation of the ulnar head with a concomitant fracture of the radius (Galeazzi lesion), treated by implantation of a Herbert Ulnar Head Prosthesis((R)). A stable distal radio-ulnar joint was achieved by careful dissection of a posterior soft tissue flap and accurate reduction of the radius.

Musculo-tendinous junction of the flexor carpi ulnaris muscle. An anatomical study.

The aim of the study was to evaluate the occurrence of the anatomical variations of the musculotendinous junction of the flexor carpi ulnaris (FCU) muscle and the variations of its insertion onto the pisiform. One hundred cadaver specimens preserved according to Thiel's method were assessed. Following careful dissection, the distance between the musculotendinous junction and the pisiform and the width of the muscle belly were determined.
