Use of Kirschner wires for percutaneous stabilization of supracondylar fractures of the humerus in children.

The results of treatment of 52 supracondylar fractures of the humerus in children by means of percutaneous transfixation with two Kirschner wires are discussed and compared with the results of other methods of treatment, such as repositioning and immobilization in a plaster cast, and traction by the Baumann or Dunlop techniques. The functional results are equivalent to those of other methods of treatment. Although the number of cases studied was only small, it appears that the cosmetic results are better, while the duration of hospitalization is markedly shorter.

[Influence of the treatment of fractures on the development of pseudoarthroses of the humerus shaft (author's transl)].

The evaluation of 98 pseudoarthroses of the shaft of the humerus showed that 42 of these occurred after conservative and 56 after surgical treatment of the original fracture. It appears that pseudoarthroses are caused in conservative treatment chiefly by the traction methods. Among the surgical methods, intramedullary nailing does not seem to bring about sufficient stabilization with a satisfactory measure of safety, whereas in the case of plate osteosynthesis, errors in respect of operation technique are mainly responsible for causing pseudoarthroses. All 98 pseudoarthroses returned to normal condition after proper plate osteosynthesis and, if necessary additional deposition of cancellous bone graft.

[Treatment of supracondylar fractures of the humerus in children and adolescents (author's transl)].

116 supracondylar fractures of the humerus were treated from 1973 to 1979. A plaster cast was applied to 68 patients after repositioning of fractures of the type Baumann I and II. 34 children were given an extension according to v. Ekesparre (fractures according to Baumann type II, III), whereas 14 patients were given surgical treatment by fixation with Kirschner wires (type III) according to Baumann). The good results obtained encouraged us to consider the extension treatment according to v. Ekesparre as a good method. Surgery appears to be indicated only if good results cannot be expected with conservative treatment or extension, or if the circulation remains disturbed or if paralysis persists.

[Last result of the first humerus prosthesis out of isoelastics (author's transl)].

The present knowledge about alloarthroplastic is given in a short summary, pointing out the special importance of the isoelastic prosthesis. The importance of a long term observation is pronounced and demonstrated by the first isoelastic shoulder prosthesis implanted 10 1/2 years ago, after resection of a semimalignant caput humerus tumor. During this time no pain, incompatibility, stress protection or loosening of the prosthesis could be observed. The bone reaction during the time of fixation is described. Within 10 1/2 years the mobility of the prosthesis as part of the shoulder joint has decreased, which is probably explained by a shrinking of the shoulder joint capsule.

[Retention in flexion of supracondylar fracture of the humerus in children. Comments apropos of the treatment of 120 displaced fractures].

The authors analyse the results obtained in 120 cases of supracondylar fracture of the humerus in children by reduction under general anaesthesia followed by fixation of the elbow in flexion, the wrist being placed close to the neck. The biomechanical basis of this technique is reviewed. It is essential that the posterior periosteum should be intact. Technical details are given together with indications. Seventy out of 120 fractures were reviewed after 2 years. There were 82 p. 100 of good results in grade II fractures. Six out of 24 grade IV fractures showed secondary displacement.

Cerclage fixation of a fractured humerus in 1775. Fact or fiction?

The description in a French journal in 1775 of cerclage wiring of a humerus has been widely accepted as the first recorded case of internal fixation of a fresh fracture. Retranslation reveals that the operation was not in fact performed, although the subject was of surgical interest at that time.

Supracondylar fracture of the humerus in children. Further experience with a study in orthopaedic decision-making.

In a study of the results of each therapeutic act in the treatment program of displaced supracondylar fractures of the humerus, 108 consecutive children were analyzed. An initial attempt at closed reduction was noted in 101 cases, with the attempt successful in 61. Of these elbows, 19 were flexed at least 120 degrees following reduction, with all 19 maintaining reduction. Twenty-two of the remaining reduced fractures were splinted in less than 120 degrees of flexion; 19 lost reduction. Traction alone, via olecranon pin or skin, was unsuccessful in achieving reduction and unreliable in maintaining reduction once achieved. Crossed Kirschner wires, placed percutaneously or under direct visualization, were uniformly successful in maintaining reduction. From these data an algorithm has been constructed to facilitate objective decision-making in the treatment of this challenging fracture.

Results of treatment of supracondylar fractures of the humerus in children with special reference to the cause and prevention of cubitus varus.

Report and analysis of the results of treatment of 56 children who exhibited a typical supracondylar fracture of the humerus necessitating reposition and treatment by clinical methods. The functional results were good on the whole and they were not clearly dependent on the nature of the treatment. The treatment consisting in manual reposition followed by application of a plaster cast was followed in about 50% of the cases by disfiguring cubitus varus. The causes of this phenomenon are discussed. The typical endorotation of the distal fracture fragment in regard to the proximal fragment plays an important part in causing cubitus varus. Cubitus varus may be prevented by wire traction through the olecranon, even if the rotation displacement persists. For this reason, this treatment is recommended. If the rotation displacement persists in the course of the traction treatment, it is advisable to use Baumann's method of demonstrating and correcting a possible varus tilting during the course of the traction treatment. If development of cubitus varus is still suspected, surgical reposition and fixation are possible, a safe method which gives good results. The surgical treatment should achieve an anatomically correct position of the fragments.

The results of treatment of comminuted fractures and fracture dislocations of the proximal humerus.

Out of 31 patients with a comminuted fracture or fracture dislocation of the proximal humerus, 21 were followed up. Twelve patients were treated operatively by internal fixation or endoprosthesis and nine were treated conservatively. The best results were achieved after internal fixation, especially in the younger patients. In the older patients, implantation of a prosthesis gave a satisfactory result.

The treatment of supracondylar fractures of the humerus in children by closed reduction and fixation with percutaneous Kirschner wires.

The results are reported of 50 consecutive cases of supracondylar fracture of the humerus in children treated by closed reduction and fixation by two parallel percutaneous Kirschner wires. A classification based on clinical and radiological findings is proposed. This is orientated both to treatment and prognosis. The technique of fixation is described and the results of four years experience of this method are reported. The long term results confirm the validity of the method, which has undoubted advantages over traditional methods. Early treatment is essential in cases with neurological or vascular complications.

Physiotherapy after fracture of the proximal end of the humerus. Comparison between two methods.

Two methods of physiotherapy after fracture of the proximal end of the humerus were compared. The study was designed as a randomized, controlled and single-blind trial. Twenty patients were assigned to two groups 10-12 days after the injury. One group was treated conventionally, the other received instructions in self-training with follow-up control of results. Objective examination and subjective assessment were made at five intervals, up to one year after the injury. The greatest improvement in function was shown in both groups between 3 and 8 weeks. The patients deemed their daily life functions to be normal 8 weeks after the injury. The objective assessment was normal at later stages. No significant differences were found between the two groups in any of the tests. Instruction in self-training with control of results including objective assessments are therefore an adequate method in the rehabilitation of these patients.

[Treatment of abducting and adducting transcondylar fractures of the humerus in children].

Abducting and adducting transcondylar fractures of the humerus have not been described in literature since they are very rare (5%). The article analyzes specific features of such fractures, methods of reposition and immobilization, gives recommendations for the repair of functions of the injured extremity. The author believes that for the successful treatment of fractures in question it is necessary to take into consideration the character of fractures, localization of periosteal connection between fragments and other specific features of each fracture.

The treatment of fractures of the capitulum of the humerus.

Fractures of the capitulum of the humerus are difficult to reduce and fix. It is possible, however, to obtain good fixation with a pin introduced from the posterior aspect. The method is described and illustrated by 8 personal cases.

Scoring system for assessing the treatment of supracondylar fractures of the humerus.

This study follows up supracondylar fractures of the humerus in 41 children. Twenty-one boys and 20 girls were observed over an average period of 4.6 yr. The ages at the time of the fracture varied between 1 and 15 yr, the highest incidence occurring between 5 and 8 yr. Twenty-four patients were treated by closed reduction and long arm cast fixation, and 17 were handled by closed reduction after overhead skeletal traction. The children who were treated with skeletal traction had comparatively more-severe fractures. Although the results have no statistical significance, a greater range of motion was regained in the elbows treated by the skeletal traction method. Following treatment, none of the patients had complications from infection or from neurovascular problems. One of the problems this study posed was in comparing our work to similar published reports. We therefore developed a new scoring system for evaluating the results achieved in treatment of this type of fracture.

Supracondylar fractures of the humerus in children treated by closed reduction and percutaneous pinning.

During the period from 1973 to 1978, 38 children with displaced supracondylar fractures of the humerus were treated at The Children's Hospital of Philadelphia by closed reduction and percutaneous pin fixation. The technical details of the procedure include (1) reduction under general anesthesia with adequate relaxation; (2) insertion of crossed pins from the medial and lateral side with the elbow in acute flexion; (3) and intraoperative clinical and roentgenographic examination of the pinned fracture with the elbow in extension to determine the adequacy of the reduction, with particular attention to the carrying angle. By Flynn's criteria acceptable results were obtained in 19 of the 25 patients studied. Three results were unacceptable due to cubitus varus of 2 degrees, 5 degrees, and 10 degrees, respectively, and three to loss of flexion. Although rotational malalignment occurred in 19 patients, as manifested by a change in shoulder rotation, in no patient was it clinically significant, either cosmetically or functionally. There were no neurologic or vascular complications from the treatment. This is a safe and reliable technique for obtaining and maintaining an excellent reduction in this difficult fracture while preserving vascular function.

[Bouquet-type internal fixation of a series of 35 fractures of the upper end of the humerus].

The authors report on 35 fractures of the humerus neck treated by "bouquet" type internal fixation. The operative technique employed is that developed by Bombard and co-workers. A few variants of this technique are described. Only fractures that were badly dislocated were internally fixated. Slight dislocations were treated for the most part by simple orthopaedic measures. This technique may be used on patients of all ages and leads to early mobilization. It might be employed to advantage in the management of slightly dislocated fractures in respiratory failure or in patients with chest injuries.

[Restorative treatment in fractures of the surgical neck of the humerus].

The treatment of 234 patients with fractures of the surgical neck of the humerus was analyzed. The conservative treatment was used in 181 of them, 53 patients were treated surgically. Satisfactory and good results were equally observed after both conservative and surgical treatment (92,5% and 96,9% respectively). However, bad results were obtained following the conservative treatment more often (in 9 of 181 patients). The surgical treatment gave bad results in 1 of 53 patients.
