Outcome of distal clavicular fracture separations and dislocations in immature skeleton.

BACKGROUND: There are only a few studies with long-term follow-up of distal clavicular injuries in children and their treatment is not clearly defined. The purpose of our study is to suggest a new classification system according to the fracture pattern and the degree of the displacement, to evaluate the long-term follow-up and also to propose an algorithm for treatment. METHODS: We conducted a retrospective study from 1983 to 2008. Seventy-five children and adolescents, age ranging from 3 to 16 years (46 >8 years), were treated in our department. We classified all these injuries into five groups according to the fracture pattern and into subgroups according to the displacement of the bony particles: greenstick fractures as group I, transverse fractures as group II, oblique fractures as group III (IIa and IIIa: undisplaced, IIb and IIIb: displaced), comminuted fractures as group IV and true dislocation of the acromioclavicular joint as group V. Sixty-three patients were treated conservatively, while 12 sustained surgical treatment. RESULTS: Fifty-nine patients were re-examined after 2-18 years. All the patients included in groups I, IIa and IIIa had no loss in the motion of their shoulder. Seven of the 29 patients in groups IIb, IIIb, IV and V appeared to have minor loss of motion. A constant score was noted in 52 patients and the results were excellent. None of the patients complained of limitations in daily activities, while five patients, who were treated conservatively, complained of visible prominence at the fracture site. One of them had a clavicular duplication, while another patient treated surgically complicated with coracoclavicular synostosis. CONCLUSION: The aforementioned proposed classification of these injuries is based on the fracture pattern and is simple, leading to decision making concerning therapy of these injuries. The functional results after a distal clavicle fracture will be excellent, either after conservative or surgical treatment. Older patients (>8 years) from groups IIb, IIIb, IV and V, with greater displacement, could be treated surgically to have better cosmetic results.

Long-term follow-up of combined fractures of the proximal radius and ulna during childhood.

Forty-five children with combined fractures of the proximal end of the radius and ulna were treated in our orthopedic department over a period of 16 years (1984-1999). The age of the patients ranged from 5 to 12 years (mean 8 years) with a peak of 7-8 years. The mechanism of injury was a fall on the outstretched hand with the elbow extended and with a valgus force being applied to the elbow. In 35 patients, closed reduction or immobilization in plaster, or both, were performed. In the other 10 patients, a surgical treatment was followed either for fractures of the radius (4) or for both the radius and ulna (6). The follow-up period ranged from 4 to 20 years (mean 12 years 3 months). The functional results were satisfactory in most cases despite the poor radiological appearance of some of them. In three patients we found a notable restriction, mainly in forearm pronation-supination and less in elbow flexion-extension, because of upper radioulnar joint synostosis. Poor results related with initial damages at the time of injury and the age of the patient (> 10 years) rather than with the way of treatment. Valgus deformity, restriction in flexion-extension, and pronation-supination were related with the extent of the initial injury but not related with the way of treatment. Overgrowth of the radial head, which had minor impact mainly on the pronation-supination, was found in the majority of cases that underwent surgical treatment. Minor residual abnormalities of the radius, ulna, or both were present without having marked functional influence.

Outcome of physeal and epiphyseal injuries of the distal tibia with intra-articular involvement.

The authors reviewed 83 physeal and epiphyseal injuries of the distal tibia with intra-articular involvement. The children, aged 11 to 14 years, were treated in the authors' department during 1987 to 1999. Treatment was nonoperative for 72.25% (60/83) and surgical for 27.75% (23/83) according to specific indications. This gives the basis for a classification of these injuries. The main purpose of the study was to investigate the long-term results of these injuries according to a radiologic classification. The parameters considered were the patient's age, the mechanism of injury, and the possibility of growth deformities or functional disorders. They were studied relative to the long-term results, with a follow-up of 2 to 13 years. Regardless of treatment, varus deformity, ranging from 10 to 15 degrees in relation to the normal opposite leg, occurred in four cases. In only one case was there painful limitation of ankle joint movement; in two other children an overgrowth of the medial malleolus was detected, with no functional impairment.

Talus fracture associated with a fracture dislocation of the distal tibia in an immature skeleton.

A 12-year-old boy with a severe injury of his right ankle was treated in the accident unit. The local condition was an extensive open wound with parts of the fractured bones prominent. Radiographs showed a severely displaced fracture of the body of the talus associated with a Salter-Harris IV injury of the distal tibia and subluxation of the ankle. After proper debridement the fractured bones were reduced and fixed. Eleven years later both fractures are completely healed without any sign of avascular necrosis, the patient has full painless ankle movement and he can perform his demanding occupation without any problem.
