To examine the long-term outcome of arthrodesis of the hip undertaken in a paediatric population in treating painful arthritis of the hip. In our patient population, most of whom live rurally in hilly terrain and have limited healthcare access and resources, hip arthrodesis has been an important surgical option for the monoarticular painful hip in a child. A follow-up investigation was undertaken on a cohort of 28 children previously reported at a mean of 4.8 years. The present study looked at 26 patients who had an arthrodesis of the hip as a child at a mean follow-up of 20 years (15 to 29).Aims
Methods
The anatomy and development of the growing acetabulum are not clearly understood. We dissected and studied histologically two acetabula from the pelvis of a three-month-old infant. Relative rates of growth at the different growth plates were assessed by comparing the height of the proliferative layer with that of the hypertrophic layer. The three bones which form the acetabulum are surrounded by growth plates on all sides except medially. These face towards the centre of the triradiate cartilage, the limbs of the triradiate cartilage and the
Osteonecrosis (ON) can cause considerable morbidity in young people who undergo treatment for acute lymphoblastic leukaemia (ALL). The aims of this study were to determine the operations undertaken for ON in this population in the UK, along with the timing of these operations and any sequential procedures that are used in different joints. We also explored the outcomes of those patients treated by core decompression (CD), and compared this with conservative management, in both the pre- or post-collapse stages of ON. UK treatment centres were contacted to obtain details regarding surgical interventions and long-term outcomes for patients who were treated for ALL and who developed ON in UKALL 2003 (the national leukaemia study which recruited patients aged 1 to 24 years at diagnosis of ALL between 2003 and 2011). Imaging of patients with ON affecting the femoral head was requested and was used to score all lesions, with subsequent imaging used to determine the final grade. Kaplan-Meier failure time plots were used to compare the use of CD with non surgical management.Aims
Methods
Delayed diagnosis is a well-known complication of a Monteggia
fracture-dislocation. If left untreated, the dislocated radial head
later becomes symptomatic. The purposes of this study were firstly,
to evaluate the clinical and radiological results of open reduction
of the radial head and secondly, to identify the factors that may
affect the outcome of this procedure. This retrospective study evaluated 30 children with a chronic
Monteggia lesion. There were 18 boys and 12 girls with a mean age
of 7.4 years (4 to 13) at the time of open reduction. The mean interval
to surgery, after the initial fracture, was 23.4 months (6 to 120).
Clinical grading used a Kim modified elbow score: radiological outcome
was recorded. The effect of the patient’s age, gender, duration
from initial injury, Bado classification, and annular ligament reconstruction
were analyzed. The mean follow-up was 42.2 months (15 to 20).Aims
Materials and Methods
There is increasing evidence that flexible flatfoot (FF) can
lead to symptoms and impairment in health-related quality of life.
As such we undertook an observational study investigating the aetiology
of this condition, to help inform management. The hypothesis was
that as well as increased body mass index (BMI) and increased flexibility of
the lower limb, an absent anterior subtalar articulation would be
associated with a flatter foot posture. A total of 84 children aged between eight and 15 years old were
prospectively recruited. The BMI for each child was calculated,
flexibility was assessed using the lower limb assessment scale (LLAS)
and foot posture was quantified using the arch height index (AHI).
Each child underwent a sagittal T1-weighted MRI scan of at least
one foot. Aims
Patients and Methods
To assess the long-term effect of distal trochanteric transfer
(DTT) on the clinical and radiographic outcomes of patients with
Legg-Calvé-Perthes’ disease (LCPD) following a varus derotational
osteotomy (VDRO). For this single centre cross-sectional retrospective study we
analysed the data of 22 patients (24 hips) with LCPD who had greater
trochanteric overgrowth (GTO), following a VDRO performed in our
institution between 1959 and 1983. GTO was defined as an articular
trochanteric distance (ATD) of <
5 mm. We compared the radiographic
and clinical outcomes of patients who underwent DTT for GTO (ten
patients, ten hips) with those who did not (12 patients, 14 hips).
Age at presentation was 6.9 years (4 to 10) and 8.0 years (3.2 to
12) respectively. Symptoms associated with the hip and general quality
of life were assessed using the Harris hip score (HHS) and the Short Form
(SF)-36 questionnaires.Aims
Patients and Methods
We wished to examine the effectiveness of tibial lengthening
using a two ring Ilizarov frame in skeletally immature patients.
This is a potentially biomechanically unstable construct which risks
the loss of axial control. We retrospectively reviewed a consecutive series of 24 boys and
26 girls, with a mean age of 8.6 years (4 to 14), who underwent
52 tibial lengthening procedures with a mean follow-up of 4.3 years
(4.0 to 16.9). Tibial alignment was measured before and after treatment
using joint orientation lines from the knee and a calculation of
the oblique plane axis.Aims
Patients and Methods
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
Percutaneous epiphysiodesis using transphyseal
screws (PETS) has been developed for the treatment of lower limb discrepancies
with the aim of replacing traditional open procedures. The goal
of this study was to evaluate its efficacy and safety at skeletal
maturity. A total of 45 consecutive patients with a mean skeletal
age of 12.7 years (8.5 to 15) were included and followed until maturity.
The mean efficacy of the femoral epiphysiodesis was 35% (14% to 87%)
at six months and 66% (21% to 100%) at maturity. The mean efficacy
of the tibial epiphysiodesis was 46% (18% to 73%) at six months
and 66% (25% to 100%) at maturity. In both groups of patients the
under-correction was significantly reduced between six months post-operatively
and skeletal maturity. The overall rate of revision was 18% (eight
patients), and seven of these revisions (87.5%) involved the tibia.
This series showed that use of the PETS technique in the femur was
safe, but that its use in the tibia was associated with a significant
rate of complications, including a valgus deformity in nine patients
(20%), leading us to abandon it in the tibia. The arrest of growth
was delayed and the final loss of growth at maturity was only 66%
of that predicted pre-operatively. This should be taken into account
in the pre-operative planning.
We describe the early results of glenoplasty as part of the technique of operative reduction of posterior dislocation of the shoulder in 29 children with obstetric brachial plexus palsy. The mean age at operation was five years (1 to 18) and they were followed up for a mean of 34 months (12 to 67). The mean Mallet score increased from 8 (5 to 13) to 12 (8 to 15) at final follow-up (p <
0.001). The mean passive forward flexion was increased by 18° (p = 0.017) and the mean passive abduction by 24° (p = 0.001). The mean passive lateral rotation also increased by 54° (p <
0.001), but passive medial rotation was reduced by a mean of only 7°. One patient required two further operations. Glenohumeral stability was achieved in all cases.
We describe three cases of infantile tibia vara
resulting from an atraumatic slip of the proximal tibial epiphysis
upon the metaphysis. There appears to be an association between
this condition and severe obesity. Radiologically, the condition
is characterised by a dome-shaped metaphysis, an open growth plate
and disruption of the continuity between the lateral borders of
the epiphysis and metaphysis, with inferomedial translation of the
proximal tibial epiphysis. All patients were treated by realignment
of the proximal tibia by distraction osteogenesis with an external
circulator fixator, and it is suggested that this is the optimal
method for correction of this complex deformity. There are differences
in the radiological features and management between conventional
infantile Blount’s disease and this ‘slipped upper tibial epiphysis’
variant.
Survivors of infantile meningococcal septicaemia often develop progressive skeletal deformity as a result of physeal damage at many sites, particularly in the lower limb. Distal tibial physeal arrest typically occurs with sparing of the distal fibular physis leading to a rapidly progressive varus deformity. There have been reports of isolated cases of this deformity, but to our knowledge there have been no papers which specifically describe the development of the deformity and the options for treatment. Surgery to correct this deformity is complex because of the patient’s age, previous scarring and the multiplanar nature of the deformity. The surgical goal is to restore leg-length equality and the mechanical axis at the end of growth. Surgery should be planned and staged throughout growth in order to achieve the best functional results. We report our experience in six patients (seven ankles) with this deformity, who were managed by corrective osteotomy using a programmable circular fixator.
We reviewed three infants with destructive osteomyelitis involving the proximal tibial epiphysis at a follow-up of eight to 22 years. All cases showed early radiographic destructive changes in the medial or lateral aspects of the epiphysis and metaphysis. Despite the ominous early appearance of the epiphysis, all cases showed spontaneous re-ossification of the epiphysis with restoration of the tibial condyle and preservation of joint congruity. The patients, however, developed a valgus or varus deformity which was treated satisfactorily with one to three proximal tibial osteotomies. The potential for regeneration of the epiphysis following infantile osteomyelitis of the proximal tibia suggests these cases should be treated expectantly with regard to joint congruity.
We have evaluated the clinical outcomes of simple excision, ulnar lengthening and the Sauvé-Kapandji procedure in the treatment of deformities of the forearm in patients with multiple hereditary osteochondromas. The medical records of 29 patients (33 forearms) were reviewed; 22 patients (22 forearms) underwent simple excision (four with ulnar lengthening) and seven the Sauvé-Kapandji procedure. Simple excision increased the mean supination of the forearm from 63.2° to 75.0° (p = 0.049). Ulnar lengthening did not significantly affect the clinical outcome. The Sauvé-Kapandji technique improved the mean pronation from 33.6° to 55.0° (p = 0.047) and supination from 70.0° to 81.4° (p = 0.045). Simple excision may improve the range of movement of the forearm but will not halt the progression of disease, particularly in younger patients. No discernable clinical or radiological improvement was noted with ulnar lengthening. The Sauvé-Kapandji procedure combined with simple excision of osteochondromas can improve stability of the wrist, movement of the forearm and the radiological appearance.
In order to treat painful subluxation or dislocation secondary to cerebral palsy, 11 patients (12 hips) underwent combined femoral and Chiari pelvic osteotomies with additional soft-tissue releases at a mean age of 14.1 years (9.1 to 17.8). Relief of pain, improvement in movement of the hip, and in sitting posture, and ease of perineal care were recorded in all, and were maintained at a mean follow-up of 13.1 years (8 to 17.5). The improvement in general mobility was marginal, but those who were able to walk benefited the most. The radiological measurements made before operation were modified afterwards to use the lateral margin of the neoacetabulum produced by the pelvic osteotomy. The radiological migration index improved from a mean of 80.6% (61% to 100%) to 13.7% (0% to 33%) (p <
0.0001). The mean changes in centre edge angle and Sharp’s angle were 72° (56° to 87°; p <
0.0001) and 12.3° (9° to 15.6°; p <
0.0001), respectively. Radiological evidence of progressive arthritic change was seen in one hip, in which only a partial reduction had been achieved, and there was early narrowing of the joint space in another. Painless heterotopic ossification was observed in one patient with athetoid quadriplegia. In seven hips the lateral Kawamura approach, elevating the greater trochanter, provided exposure for both osteotomies and allowed the construction of a dome-shaped iliac osteotomy, while protecting the sciatic nerve.
We reviewed 34 knees in 24 children after a double-elevating osteotomy for late-presenting infantile Blount’s disease. The mean age of patients was 9.1 years (7 to 13.5). All knees were in Langenskiöld stages IV to VI. The operative technique corrected the depression of the medial joint line by an elevating osteotomy, and the remaining tibial varus and internal torsion by an osteotomy just below the apophysis. In the more recent patients (19 knees), a proximal lateral tibial epiphysiodesis was performed at the same time. The mean pre-operative angle of depression of the medial tibial plateau of 49° (40° to 60°) was corrected to a mean of 26° (20° to 30°), which was maintained at follow-up. The femoral deformity was too small to warrant femoral osteotomy in any of our patients. The mean pre-operative mechanical varus of 30.6° (14° to 66°) was corrected to 0° to 5° of mechanical valgus in 29 knees. In five knees, there was an undercorrection of 2° to 5° of mechanical varus. At follow-up a further eight knees, in which lateral epiphysiodesis was delayed beyond five months, developed recurrent tibial varus associated with fusion of the medial proximal tibial physis.
