Aims.
Ninety-eight children with severely displaced supracondylar fractures of the humerus were treated by straight lateral traction. After a mean follow-up period of 3.5 years there were 90 satisfactory and only eight unsatisfactory results.
We have reviewed 12 cases of fracture-separation of the distal humeral epiphysis, three of which were initially misdiagnosed as fractures of the lateral condyle and one as an elbow dislocation.
Introduction: Supracondylar fracture of the humerus is a common upper limb fracture in children. Treatment is controversial and often technically difficult; complications are common.
Introduction: Closed reduction and percutaneous pinning techniques for displaced supracondylar fractures of the humerus in children have overcome disastrous ischemic complications and long inpatient treatment. Closed reduction of those highly unstable fractures and the demanding pin placement itself are potential sources of failure for the inexperienced reflected by the rate of cubitus varus which is still about 5 to 15% in recent series. Rotational primary and residual displacement has to be appreciated to prevent permanent cosmetic deformity. Malrotation is the major source of instability since bicolumnar support is lost which allows the distal fragment to tilt. Anatomy: The transverse section of the distal humerus is the key to all stability related problems faced in supra-condylar fractures of the humerus in children. In the supracondylar region the radial and ulnar column are only connected by a thin bony wafer which results from the presence of the cubital and olecranon fossa. In case of a fracture. In case of a fracture rotation leads to decrease of bony contact and hence to instability. Epidemiology: Elbow fractures account for 7–10% of all pediatric fractures whereof 80–90% are located at the distal humerus with 80% involvement of the supracondylar region. Most of the supracondylar fractures occur between ages 5 and 10 years. Mechanism of injury: Fall from a height, usually from a household object in the age group <
3 years or from a playground equipment in children >
4 years on the outstretched nondominant arm (indirect elbow trauma). 96% of all supracondylar fractures are extension type injuries. Open fractures, mostly grade 1, occur when the anterior spike of the proximal fragment pierces through the brachialis muscle and the skin of the cubital fossa. Their incidence is about 1–3% in major referral centers. Differential diagnosis: Supracondylar fractures have to be differentiated from transcondylar fractures and dislocations of the elbow. In a supracondylar fracture the fracture line stays proximal to the distal humerus physis. If it runs across it, it is most likely a supracondylar fracture. Dislocations of the elbow typically after the age of 10 years. Neurologic compromise: Fracture related peripheral neuropathies have an incidence of 10 to 17%. With rare exceptions concomitant nerve lesion recover spontaneously within a time range of 1 to 4 months. The rate of iatrogenic nerve injuries is 3%–16% with the ulnar nerve being the most susceptible due to inadvertent pinning. Despite a high recovery rate, they are a nuisance for the patients. Vascular compromise: Early recognition of vascular compromise with subsequent reduction and fixation of the fracture and avoidance of extreme flexion at the elbow have decreased the incidence of ischemic complications. An initially absent radial pulse is found in up to 19% in displaced fractures. Closed reduction restores pulsation in about 80%. Patients with postreduction lack of pulse or poor capillary refill should undergo vascular revision. There is still controversy regarding the management of a post reduction pink, warm but pulse less hand with adequate capillary refill. Simple observation and conservative management leads to a favourable clinical outcome in most cases but cold intolerance or exercise induced ischemic symptoms is a potential sequel. Treatment:. Undisplaced fractures: simple immobilisation e.g. collar and cuff. Incomplete displacement: in case of malrotation and/or age-related unacceptable extension (>
20° in patients older than 6 years) closed reduction and pinning otherwise conservative management. Complete displacement: Attempt for closed reduction and percutaneous pinning. Irreducibility is found in up to 22%. Open reduction is most widely as a last resort. Complications:. Infection. Occasionally, superficial infection after pinning occurs despite all preventive measure (wires left protruding through the skin should not be covered by plaster to prevent rubbing; pin care instruction for the parents; regular follow-up for pin site inspection).
Displaced fractures of the lateral condyle of the humerus are
frequently managed surgically with the aim of avoiding nonunion,
malunion, disturbances of growth and later arthritis. The ideal
method of fixation is however not known, and treatment varies between
surgeons and hospitals. The aim of this study was to compare the
outcome of two well-established forms of surgical treatment, Kirschner
wire (K-wire) and screw fixation. A retrospective cohort study of children who underwent surgical
treatment for a fracture of the lateral condyle of the humerus between
January 2005 and December 2014 at two centres was undertaken. Pre,
intraoperative and postoperative characteristics were evaluated. A total of 336 children were included in the study. Their mean
age at the time of injury was 5.8 years (0 to 15) with a male:female
patient ratio of 3:2. A total of 243 (72%) had a Milch II fracture
and the fracture was displaced by > 2 mm in 228 (68%). In all, 235
patients underwent K-wire fixation and 101 had screw fixation. Aims
Patients and Methods
We reviewed the clinical and radiological results of six patients who had sustained traumatic separation of the distal epiphysis of the humerus at birth. The correct diagnosis was made from plain radiographs and often supplemented with ultrasonography, MRI and arthrography. An orthopaedic surgeon saw two patients within two days of birth, and the other four were seen at between nine and 30 days. The two neonates underwent unsuccessful attempts at closed reduction. In the remaining patients, seen after the age of eight days, no attempt at reduction was made. All six displaced fractures were immobilised in a cast with the elbow at 90° of flexion and the forearm pronated. When seen at a mean of 58 months (16 to 120) after injury, the clinical and radiological results were excellent in five patients, with complete realignment of the injury. In one patient the forearm lay in slightly reduced valgus with the elbow in full extension. Traumatic separation of the distal epiphysis of the humerus may be missed on the maternity wards and not diagnosed until after discharge from hospital. However, even when no attempt is made to reduce the displaced epiphysis, a good clinical result can be expected.
Recent reports have suggested that a delay in the management of type-III supracondylar fractures of the humerus does not affect the outcome. In this retrospective study we examined whether the timing of surgery affected peri-operative complications, or the need for open reduction. There were 171 children with a closed type-III supracondylar fracture of the humerus and no vascular compromise in our study. They were divided into two groups: those treated less than eight hours from presentation to the Accident and Emergency Department (126 children), and those treated more than eight hours from presentation (45 children). There were no differences in the rate of complications between the groups, but children waiting more than eight hours for reduction were more likely to undergo an open reduction (33.3%
We reviewed 22 children with cubitus varus who had been treated by a reverse V osteotomy and fixation by cross-pinning and wiring. The mean pre-operative humeral-elbow-wrist angle was −16.9° (−25° to +9°) and at the latest follow-up it was +7.3° (−2° to +14°). No child had a lateral prominence greater than 5 mm after correction. An excellent result was achieved in 20 children and a good result in two. We believe that this osteotomy has the advantages of better inherent stability, the avoidance of a prominent lateral condyle after correction and firm fixation allowing early movement.
