Background

There are well-defined criteria for the treatment of distal radius fractures but the impact of an unrepaired fracture of the styloid process of the ulnar on recovery after operative treatment is uncertain. This study evaluated radiological and functional results after different operative treatment procedures of distal radius fractures in patients with an untreated fracture of the styloid process of the ulna and those without such a fracture.

Methods

Out of 480 patients with operatively treated distal radius fractures 238 were examined at least 1 year after injury. The fracture of the styloid process of the ulna was not repaired. Three groups (patients without a fracture of the styloid process of the ulna, patients with a tip fracture and those with a basal fracture) were evaluated by multivariate analysis (MANOVA) in order to detect influences of the fracture of the styloid process of the ulna on the radiological and functional results.

Results

Neither the existence nor the location of the fracture of the styloid process of the ulna had a significant effect on the radiological and functional results (pfunction=0,849, pradiology=0,330, pscores=0,426, MANOVA).

Conclusions

The repair of a fracture of the styloid process of the ulna is not necessary if reduction and fixation of the distal radius fracture is anatomical and stable.  相似文献

A healthy, right-handed 34-year-old man was injured by repeated direct blows delivered to his left upper arm with a baseball bat. These blows led to a posterior dislocation of the elbow joint, associated with fractures of the radial head and the coronoid process. There was bone loss on the fractured joint surface of the olecranon, with simultaneous ipsilateral trauma to the ulna. The correct surgical approach in the case of such fractures is still the subject of some controversy. The treatment can have serious complications. The results of treatment are often poor, especially because of persisting instability and stiffness of the elbow following a long period of immobilisation. Few studies have been concentrated on this topic up to now. We report on the functional and radiological results 24 months after the treatment of this rare, open "shock triad in the elbow."  相似文献

Zusammenfassung Luxationen und Luxationsfrakturen im Ellenbogengelenk sind in der Mehrzahl der Fälle Verrenkungen des Unterarmes gegenüber dem Oberarm nach hinten. In 10–15% dieser Fälle liegt dabei ein Abbruch des Kronenfortsatzes in Verbindung mit einer Fraktur oder Luxation des Radiusköpfchens vor. Ist eine Rekonstruktion des Radiusköpfchens bei solchen Verletzungen nicht möglich, so ist zur Erhaltung einer stabilen Gelenkfunktion und zur Verhütung einer Reluxation der Processus coronoideus vor allem dann operativ zu rekonstruieren, wenn das ausgebrochene Fragment mehr als 1/6 der Incisura trochlearis ausmacht. Die Notwendigkeit der operativen Rekonstruktion ergibt sich aus den biomechanischen Gegebenheiten, nach denen dem Radiusköpfchen und dem Processus coronoideus eine wichtige Kraftträgerfunktion zukommt.
Biochemical problems in elbow joint dislocations with coronoid and capitulum radii fractures
Summary Dorsal dislocation occurs in 80% of all fracture dislocations of the elbow joint. In 10–15% of these injuries the coronoid process and the radial head are involved. If this injury causes the defect of the radial head — which means the loss of the main supporting part of the joint, — it is only the coronoid process which gives stability to the elbow joint. Therefore, in cases of coronoid fracture it is of utmost importance to reconstruct the coronoid process, if the fracture involves more than 1/6 of the incisura olecrani. Advisable for fixation is the use of a lag screw. In some cases the reconstruction with autogenous bone graft or osteotomy of the olecranon is indicated.

Zusammenfassung Ellenbogenluxationsfrakturen zeigen in 80% eine Verrenkung des Unterarmes nach hinten. Bei 10–15% der Fälle davon liegt eine Abscherfraktur des Proc. coronoideus und Luxationsfraktur des Radiusköpfchens vor. Wenn das Radiusköpfchen als Hauptkraftträger bei axialer Belastung reseziert werden muß, so garantiert nur die unverletzte Olecranonpfanne mit ihrem Krümmungssektor von 180–199° zusammen mit dem Kapselbandapparat eine ausreichend stabile Gelenkführung. Deshalb sollte bei Verlust des Radiusköpfchens der Abbruch von mehr als 1/6 im Bereich des Proc. coronoideus mittels Zugschraube, autologer Knochenspanplastik oder Verschiebeosteotomie zur Verhinderung der Reluxation rekonstruiert werden.  相似文献

Fractures of the calcaneus are still severe injuries of the lower extremities which is reflected in the above average times of disability and the very different results of treatment compared to other fractures of the lower extremities. Therefore therapeutic decision-making for these patients requires, besides knowledge of the current treatment options, an individual and patient-orientated assessment. Various studies have shown that accurate reconstruction of the subtalar joint leads to a better outcome in these patients which will strengthen the importance of intraoperative digital 3D imaging techniques in the future.  相似文献

A classification of fractures of the shoulder is given and diagnostic procedures are discussed. In most of the cases functional therapy is the treatment of choice. There exist a few indications for reduction and operation. Fractures of the scapula are briefly reviewed. For fractures of the proximal humerus in children a conservative approach is indicated. Different forms of fractures require an individual treatment.  相似文献

The most prevalent fractures managed by trauma surgeons are those involving the distal radius. The injury occurs in two peaks of prevalence: the first peak around the age of 10 years and the second peak around the age of 60 years. Distal radius fracture management requires sensitive diagnostics and classification. The objectives of treatment are the reconstruction of a pain-free unlimited durable functioning of the wrist and avoidance of typical fracture complications. Non-operative conservative management is generally employed for stable non-displaced fractures of the distal radius with the expectation of a good functional outcome. Unstable comminuted fractures with intra-articular and extra-articular fragment zones are initially set in a closed operation and finally by osteosynthesis. An armament of surgical implants is available for instable fractures requiring fixation. Palmar locked plate osteosynthesis has been established in recent years as the gold standard for operative management of distal radius fractures. Complex Working Group on Osteosynthesis (AO) classification type 3 fractures require extensive preoperative diagnostics to identify and treat typical associated injuries around the wrist.  相似文献

Upper ankle injuries are the most common reason for presentation in emergency departments. The initial treatment is often left in the hands of young clinical professionals. While the mechanism of injury might appear banal, insufficient diagnosis and treatment can lead to long periods of disability and functional impairment of the joint. Therefore, it is the aim of this work to provide a thorough understanding of the anatomy, biomechanics, mechanism of injury, diagnostic and operative procedures of ankle joint fractures.  相似文献
