We present the clinical and radiographic outcome of 81 children
with Gartland type I to III supracondylar humeral fractures at a
minimum follow-up of ten years (mean 12.1 years; 10.3 to 16.1) following
injury. The clinical and functional outcomes are compared with normal
age- and gender-matched individuals. The population-based study
setting was first identified from the institutional registries;
the rate of participation was 76%. Controls were randomly selected
from Finnish National Population Registry.Aims
Patients and Methods
Between 1978 and 1997 all newborns in the Austrian province of Tyrol were reviewed regarding hip dysplasia and related surgery. This involved a mean of 8257 births per year (7766 to 8858). Two observation periods were determined: 1978 to 1982 (clinical examination alone) and 1993 to 1997 (clinical examination and universal ultrasound screening). A retrospective analysis compared the number and cost of interventions due to hip dysplasia in three patient age groups: A, 0 to <
1.5 years; B, ≥ 1.5 to <
15 years; and C, ≥ 15 to <
35 years. In group A, there was a decrease in hip reductions from a mean of 25.2 ( An increase of €57 000 in the overall cost per year for the second period (1993 to 1997) was seen, mainly due to the screening programme. However, there was a marked reduction in costs of all surgical and non-surgical treatments for dysplastic hips from €410 000 (1978 to 1982) to €117 000 (1993 to 1997). We believe the small proportional increase in costs of the universal ultrasound screening programme is justifiable as it was associated with a reduction in the number of non-surgical and surgical interventions. We therefore recommend universal hip ultrasound screening for neonates.
The recognition of hips at risk of displacement
in children with cerebral palsy (CP) is a difficult problem for
the orthopaedic surgeon. The Gross Motor Function Classification
System (GMFCS) and head–shaft angle (HSA) are prognostic factors
for hip displacement. However, reference values for HSA are lacking.
This study describes and compares the development of HSA in normal
hips and children with CP. We selected 33 children from a retrospective cohort with unilateral
developmental dysplasia of the hip (DDH) (five boys, 28 girls) and
50 children (35 boys, 15 girls) with CP with GMFCS levels II to
V. HSA of normal developing hips was measured at the contralateral
hip of unilateral DDH children (33 hips) and HSA of CP children
was measured in both hips (100 hips). Measurements were taken from
the radiographs of the children at age two, four and seven years.
The normal hip HSA decreased by 2° per year (p <
0.001). In children
with CP with GMFCS levels II and III HSA decreased by 0.6° (p =
0.046) and 0.9° (p = 0.049) per year, respectively. The HSA did
not alter significantly in GMFCS levels IV and V. Between the ages of two and eight years, the HSA decreases in
normal hips and CP children with GMFCS level, II to III but does
not change in GMFCS levels IV to V. As HSA has a prognostic value
for hip displacement, these reference values may help the orthopaedic
surgeon to predict future hip displacement in children with CP. Cite this article:

The traditional techniques involving an oblique
tunnel or triangular wedge resection to approach a central or mixed-type
physeal bar are hindered by poor visualisation of the bar. This
may be overcome by a complete transverse osteotomy at the metaphysis
near the growth plate or a direct vertical approach to the bar.
Ilizarov external fixation using small wires allows firm fixation
of the short physis-bearing fragment, and can also correct an associated angular
deformity and permit limb lengthening. We accurately approached and successfully excised ten central-
or mixed-type bars; six in the distal femur, two in the proximal
tibia and two in the distal tibia, without damaging the uninvolved
physis, and corrected the associated angular deformity and leg-length
discrepancy. Callus formation was slightly delayed because of periosteal
elevation and stretching during resection of the bar. The resultant
resection of the bar was satisfactory in seven patients and fair
in three as assessed using a by a modified Williamson–Staheli classification. Cite this article:

The aim of this retrospective multicentre study was to report the continued occurrence of compartment syndrome secondary to paediatric supracondylar humeral fractures in the period 1995 to 2005. The inclusion criteria were children with a closed, low-energy supracondylar fracture with no associated fractures or vascular compromise, who subsequently developed compartment syndrome. There were 11 patients (seven girls and four boys) identified from eight hospitals in three countries. Ten patients with severe elbow swelling documented at presentation had a mean delay before surgery of 22 hours (6 to 64). One patient without severe swelling documented at presentation suffered arterial entrapment following reduction, with a subsequent compartment syndrome requiring fasciotomy 25 hours after the index procedure. This series is noteworthy, as all patients had low-energy injuries and presented with an intact radial pulse. Significant swelling at presentation and delay in fracture reduction may be important warning signs for the development of a compartment syndrome in children with supracondylar fractures of the humerus.
A small proportion of children with Gartland
type III supracondylar humeral fracture (SCHF) experience troubling limited
or delayed recovery after operative treatment. We hypothesised that
the fracture level relative to the isthmus of the humerus would
affect the outcome. We retrospectively reviewed 230 children who underwent closed
reduction and percutaneous pinning (CRPP) for their Gartland type
III SCHFs between March 2003 and December 2012. There were 144 boys
and 86 girls, with the mean age of six years (1.1 to 15.2). The
clinico-radiological characteristics and surgical outcomes (recovery
of the elbow range of movement, post-operative angulation, and the
final Flynn grade) were recorded. Multivariate analysis was employed
to identify prognostic factors that influenced outcome, including
fracture level. Multivariate analysis revealed that a fracture below
the humeral isthmus was significantly associated with poor prognosis
in terms of the range of elbow movement (p <
0.001), angulation
(p = 0.001) and Flynn grade (p = 0.003). Age over ten years was also
a poor prognostic factor for recovery of the range of elbow movement (p
= 0.027). This is the first study demonstrating a subclassification system
of Gartland III fractures with prognostic significance. This will
guide surgeons in peri-operative planning and counselling as well
as directing future research aimed at improving outcomes. Cite this article:

The painful subluxed or dislocated hip in adults
with cerebral palsy presents a challenging problem. Prosthetic dislocation
and heterotopic ossification are particular concerns. We present
the first reported series of 19 such patients (20 hips) treated
with hip resurfacing and proximal femoral osteotomy. The pre-operative
Gross Motor Function Classification System (GMFCS) was level V in
13 (68%) patients, level IV in three (16%), level III in one (5%) and
level II in two (11%). The mean age at operation was 37 years (13
to 57). The mean follow-up was 8.0 years (2.7 to 11.6), and 16 of the
18 (89%) contactable patients or their carers felt that the surgery
had been worthwhile. Pain was relieved in 16 of the 18 surviving
hips (89%) at the last follow-up, and the GMFCS level had improved
in seven (37%) patients. There were two (10%) early dislocations;
three hips (15%) required revision of femoral fixation, and two
hips (10%) required revision, for late traumatic fracture of the
femoral neck and extra-articular impingement, respectively. Hence
there were significant surgical complications in a total of seven
hips (35%). No hips required revision for instability, and there
were no cases of heterotopic ossification. We recommend hip resurfacing with proximal femoral osteotomy
for the treatment of the painful subluxed or dislocated hip in patients
with cerebral palsy.
We present the results of treatment of developmental dysplasia of the hip in infancy with the Pavlik harness using a United Kingdom screening programme with ultrasound-guided supervision. Initially, 128 consecutive hips in 77 patients were reviewed over a 40-month period; 123 of these were finally included in the study. The mean age of the patients at the start of treatment was five weeks (1 to 12). All hips were examined clinically and monitored with ultrasound scanning. Failure of treatment was defined as an inability to maintain reduction with the harness. All hips diagnosed with dysplasia or subluxation but not dislocation were managed successfully in the harness. There were 43 dislocated hips, of which 39 were reducible, but six failed treatment in the harness. There were four dislocated but irreducible hips which all failed treatment in the harness. One hip appeared to be successfully treated in the harness but showed persistent radiological dysplasia at 12 and 24 months. Grade 1 avascular necrosis was identified radiologically in three patients at 12 months.
