儿童后内侧和后外侧移位肱骨髁上骨折和肘内翻畸形之间的关系

目的探讨儿童后内侧和后外侧移位肱骨髁上骨折和发生肘内翻畸形之间的关系。方法采用闭合复位克氏针内固定治疗33例GartlandⅢ型肱骨髁上骨折患儿(ⅢA型18例,ⅢB型15例),术后辅以石膏托外固定3~4周。术后在肘关节正、侧位X线片上测量提携角和肘关节的运动范围,观察提携角变化,分析移位方向和肘内翻的关系。结果患儿均获随访,时间1~2年。18例ⅢA型骨折者提携角丢失15.2°±5.1°,15例ⅢB型骨折者提携角丢失8.8°±3.5°。ⅢA型骨折与ⅢB型骨折致肘内翻的程度比较差异有统计学意义(P0.05)。患者均未出现肘关节活动受限。根据Flynn标准:18例ⅢA型骨折患儿中10例为良,8例为差;15例ⅢB型骨折患儿中9例为良,6例为差。结论ⅢA型骨折较ⅢB型骨折出现肘内翻的可能性更大。即使术后得到了解剖复位,ⅢA型骨折仍可能导致肘内翻畸形,这可能是ⅢA型骨折中内侧骨皮质的压缩,或伴有骨骺损伤所造成。     

Correlation between posteromedial or posterolateral displacement and cubitus varus deformity in supracondylar humerus fractures in children

Purpose Cubitus varus deformity is one of the most common complications after displaced supracondylar humeral fractures in children. The purpose of this study was to evaluate the relationship between the fracture displacement and cubitus varus deformity in displaced supracondylar humerus fractures. Methods Seventeen patients (11 males/6 females; mean age 7 years) with cubitus varus deformities occurring after Gartland type III posteromedial or posterolateral displaced supracondylar humerus fractures were evaluated with clinical and serial radiographic examinations. All patients had been treated surgically by open reduction through a medial approach and percutaneous cross-pinning. All fractures were reduced anatomically. Ten of the patients were operated within the first 24 h. The time interval between the initial injury and the surgical procedure for the remaining seven patients was 5.3 days on average (range 2–10 days). The carrying angle and range of motion of the elbow were measured throughout the follow-up period. The mean follow-up time was 3.7 years (range 2–12 years). Results Five patients with type III-B fractures had a mean carrying angle loss of 8.8° (range 6–10°), whereas for the remaining 12 type III-A patients the mean loss was 15° (range 6–29°) (P = 0.019). None of the patients in this study demonstrated limited elbow motion. According to the Flynn criteria, the results were good in five type III-B patients. There was no statistically significant relationship between the loss of carrying angle and the delay before the surgical procedure (P = 0.615 in type III-A, P = 0.096 in type III-B). Conclusions The carrying angle loss was more significant in type III-A fractures compared with type III-B in this series. These results suggest that although anatomic reduction has been achieved by surgical treatment without loss of reduction, there is still a risk for cubitus varus deformity for type III-A fractures due to the initial compression of the medial column or, in other words, physeal injury.     

Correction of cubitus varus by French or dome osteotomy: a comparative study

BACKGROUND: The purpose of this study was to compare the outcomes of two different techniques of supracondylar osteotomy, French osteotomy and dome osteotomy, for the correction of posttraumatic cubitus varus. METHODS: A comparative randomized study was undertaken of 25 patients (average age 10 years) with an established posttraumatic cubitus varus deformity (mean time from injury to corrective osteotomy, 1.7 years). Patients were followed-up with for 1 year, and carrying angle, Baumann's angle, and internal rotation deformity were measured. Postoperative complications were assessed. RESULTS: A significant (p < 0.01) correction of carrying angle and Baumann's angle was achieved with both techniques, with no statistically significant differences between them. Although internal rotation deformity was corrected by both techniques, the correction was significantly greater with the dome osteotomy (p < 0.01). However, the persistence of internal rotation did not seem to affect the final outcome. There was a higher incidence of postoperative complications in the dome osteotomy group, including infection (1), inadequate correction (1), nerve palsy (1), loss of motion (5), and circulatory compromise (1). CONCLUSION: The dome osteotomy is technically more difficult than the French osteotomy and has a higher incidence of complications. We suggest that the French osteotomy be used for the correction of cubitus varus after supracondylar fractures of the elbow in children.

Corrective French's osteotomy in treatment of cubitus varus]

Cubitus varus is the most common late complication of supracondylar fracture of the humerus in children. The normal carrying angle can be restored by supracondylar osteotomy. This operation using the technique described by French. was done in 10 patients. During follow up examination motion of the cubitus was assessed and compared with an uninjured side. The x-ray examination included evaluation of the carrying angle. Favourite results were confirmed by restoration of carrying angle with minor loss of mobility of the elbow joint with no recurrence of the varus deformity during follow up.     

Supracondylar humeral osteotomy in children with severe posttraumatic cubitus varus deformity

The authors report the results of corrective osteotomy of the humerus in 11 children with severe posttraumatic cubitus varus deformity. The average carrying angle on the affected side was -24.4 degrees, and there was an average internal rotation deformity of the distal humerus of 22 degrees. Flexion and extension of the injured elbow were severely limited. A supracondylar lateral wedge osteotomy of the humerus was performed keeping the medial cortex intact. Two K-wires served as levers to correct the angular and rotational deformity of the elbow and then as fixation material to hold the osteotomy fragments. Postoperatively we immobilized the elbows in 90 degrees flexion for 3 to 4 weeks. There was no loss of the postoperative osteotomy alignment in most cases. Recurrence of mild varus deformity (-5 degrees and -7 degrees) occurred in only two patients. At the end of the follow-up we observed excellent results in 9 patients with an average carrying angle of 7.2 degrees (range 5-10 degrees).     

A new three-dimensional osteotomy for cubitus varus deformity after supracondylar fracture of the humerus in children

In the past, supracondylar osteotomy for the correction of cubitus varus deformity has been associated with a high failure rate and significant complications, even in simple lateral closing wedge osteotomy. This is because the supracondylar area is thin and fixation is difficult to maintain. In cubitus varus deformity, not only medial, but posterior, tilt and internal rotation of the distal fragment also frequently occurs. To correct all these deformities and to achieve a wide bony contact and more rigid fixation than simple lateral closing wedge osteotomy, we propose a new three-dimensional osteotomy. Among 12 patients who received this osteotomy, 11 had an excellent result and one had a good result.     

Supracondylar fractures of the humerus in children. Analysis at maturity of fifty-three patients treated conservatively

From a pool of 131 supracondylar fractures of the humerus in 131 patients who were treated conservatively, all of which healed in an average time of 4.5 weeks without complications related to the treatment itself, the cases of fifty-three patients were reviewed at maturity. The average age at follow-up was twenty-six years. Nine patients had unimportant limitation of elbow motion, and slight atrophy of the musculature of the arm or forearm, or of both, was present in six patients. Arm-length discrepancy was never observed. The carrying angle remained at about the same value that had been present at the time of fracture-healing in eighteen patients, decreased in twenty-two patients, and increased in thirteen. Malrotation of the distal fragment of the fracture only rarely caused medial tilting of the fragment with consequent cubitus varus. Varus deformity was present in four patients and valgus deformity, in three. None of the patients with valgus deformity had ulnar-nerve palsy. According to our results, varus and valgus deformities of the elbow after supracondylar fractures of the humerus seem to be caused either by growth imbalance of the growth plate of the distal end of the humerus (four patients) or by malreduction of the fracture (three patients). Twelve patients in the entire pool had neurological complications at the time of the fracture. Ten of those patients fully recovered from the deficit, whereas two--one with a radial-nerve deficit and the other with ulnar-nerve involvement--still had neurological impairment at follow-up.

Fracture separation of the distal humeral epiphysis in children younger than three years old

This study evaluated the change of carrying angle and the causes of cubitus varus after the fracture separation of the distal humeral epiphysis in young children. Twelve cases of fracture separation of distal humeral epiphysis were treated from January 1995 to July 1997. The age of all patients was younger than 3 years old. A metaphyseal fragment was seen in all cases (Salter-Harris type II), but the size of the metaphyseal fragment was either a very small flake or a large Thurston-Holland fragment. Posteromedial displacement was seen in all cases. There were three treatment groups: closed reduction with percutaneous pinning, closed reduction with cast, and cast without reduction. Follow-up period averaged 23.5 months (range, 12-40). Cubitus varus deformity was seen in seven cases, and six of them had a partial defect of the medial condyle that was avascular necrosis. The methods of treatment, age of injury, and the type of epiphyseal injury had no influence on the development of cubitus varus, but avascular necrosis of the medial condyle was related to the cubitus varus deformity (p<0.05). The results of this study suggest that fracture separation of distal humeral epiphysis in young children is likely to produce cubitus varus deformity with the development of avascular necrosis of the medial humeral condyle.     

Posttraumatic progressive cubitus varus deformity managed by lateral column shortening: A novel surgical technique

The outward angulation of elbow with supinated forearm is cubitus varus deformity. This deformity is often seen as sequelae of malunited supracondylar fracture of humerus in paediatric age group of 5e8 years. The deformity is usually non-progressive, but in cases of physeal injury or congenital bony bar formation in the medial condyle of humerus, the deformity is progressive and can be grotesque in appearance. Various types of osteotomies are defined for standard non-progressive cubitus varus deformity, while multiple surgeries are required for progressive deformity until skeletal maturity. In this study we described a novel surgical approach and osteotomy of distal humerus in a 5 years old boy having grotesque progressive cubitus varus deformity, achieving good surgical outcome.

Conservative Treatment with Active Exercises in Osteoarthritis of the Hip

Six patients with cubitus varus deformity after a supracondylar fracture of the humerus had ulnar nerve palsy 7 (3–14) years following the fracture. All the patients showed anterior dislocation of the ulnar nerve during elbow flexion. In cubitus varus deformity, medial shifting of the triceps muscle occurs, which pushes the ulnar nerve anteriorly and frequently causes ulnar-nerve dislocation. Five of the 6 patients under-went surgery with subsequent improvement.

Osteotomy for cubitus varus:A simple technique in 10 children

10 children with cubitus varus deformity after supracondylar fractures were operated on with a supracondylar lateral closing wedge osteotomy. The medial cortical periosteal hinge was left intact and the osteotomy stabilized with two Kirschner wires and a tension-band wire loop. The osteotomies healed within 2 months, without any complications or recurrence of the deformity. The outcome was satisfactory as regards both cosmesis and mobility.
