Sixty-four patellar fractures treated either by internal fixation or by patellectomy were reviewed retrospectively from 3.5 to 10.1 years (average 6.2 years) after operation. Results were assessed subjectively and objectively. Of the 64 patients, 45% had a good result, 27% fair and 28% poor. On the whole, patellectomy produced better results (60% good, 20% fair, 20% poor), than internal fixatio...

Bicondylar coronal plane fracture, eponymically named Hoffa fractures, is an extremely rare injury. We present a case of isolated unilateral bicondylar Hoffa fracture that was successfully treated with open reduction and internal fixation using headless compression screws with satisfactory results. We inserted posteroanteriorly oriented Acutrak screws perpendicular to the fracture plane via lat...

Vascular complications associated with supracondylar fracture of humerus are well recognised. Less well recognised are neurological injuries associated with this fracture. A prospective study was conducted to explore the role of open reduction and internal fixation of this fracture. The article presents the incidence of nerve lesions in 46 cases of supracondylar fracture of humerus; review of p...

ASTRONOMY AND ASTROPHYSICS Gamma-ray bursts from internal shocks in a relativistic wind : an hydrodynamical study. Abstract. The internal shock model for gamma-ray bursts involves shocks taking place in a relativistic wind with a very inhomogeneous initial distribution of the Lorentz factor. We have developed a 1D lagrangian hydrocode to follow the evolution of such a wind and the results we ha...

Results There were 102 type C pilon fractures in 99 patients, whose mean age was 42 years (16 to 86) and 77 were male. Primary open reduction internal fixation (ORIF) was performed in 73 patients (71.6%), whilst 20 (19.6%) underwent primary external fixation with delayed ORIF. There were 18 wound infections (17.6%). A total of nine (8.8%) were deep and nine were superficial. Infection was assoc...

AO Principles are described today as follows: * appropriate reduction * appropriate stabilization * preservation of vascularity * painless early mobilization These requirements can all be met by intramedullary osteosynthesis for suitable indications. The modern generation of nails is highly user-friendly and application of the systems is very safe. Outcome predictions favor reamed locked nailin...

fractures of the femur has been mentioned in the literature only twice (Lamphier, Trott and Shortell 1948, Kennedy 1950). It constituted only 1 per cent of the appliances for internal fixation of this fracture sold by a major United States surgical supply house in 1954. We began to use the Moe plate in 1945 because of mechanical failures at the junction of the three-flanged nail and lateral pla...

Important advances have been made within the last two decades in the field of fracture management. The development of the AO internal fixation system and the advances in cast bracing techniques are but two of the improvements worthy of mention. It is, however, in the field of external fixation of fractures that the greatest advances have been made. This paper traces the history of external fixa...

BACKGROUND Controversy exists regarding the optimal treatment for patients with displaced intracapsular fractures of the proximal femur. The recognised treatment alternatives are arthroplasty and internal fixation. The principal criticism of internal fixation is the high rate of non-union; up to 30% of patients will have a failure of the fixation leading to revision surgery. We believe that imp...

Since the ancient times, man was faced with the problem of fracture treatment, which is first described in the records from ancient Egypt. Ever since, many treatment methods have been developed, but the real revolution in the fracture treatment was achieved by internal fixation. Since it was described for the first time, at the end of the 18th century, this method has continuously developed, bu...
