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
High-quality clinical research in children’s orthopaedic surgery
has lagged behind other surgical subspecialties. This study used
a consensus-based approach to identify research priorities for clinical
trials in children’s orthopaedics. A modified Delphi technique was used, which involved an initial
scoping survey, a two-round Delphi process and an expert panel formed
of members of the British Society of Children’s Orthopaedic Surgery.
The survey was conducted amongst orthopaedic surgeons treating children
in the United Kingdom and Ireland.Aims
Methods
This study analysed the clinical and radiological outcome of
anatomical reduction of a moderate or severe stable slipped capital
femoral epiphysis (SCFE) treated by subcapital osteotomy (a modified
Dunn osteotomy) through the surgical approach described by Ganz. We prospectively studied 31 patients (32 hips; 16 females and
five males; mean age 14.3 years) with SCFE. On the Southwick classification,
ten were of moderate severity (head-shaft angle >
30° to 60°) and
22 were severe (head-shaft angle >
60°). Each underwent open reduction
and internal fixation using an intracapsular osteotomy through the
physeal growth plate after safe surgical hip dislocation. Unlike
the conventional procedure, 25 hips did not need an osteotomy of
the apophysis of the great trochanter and were managed using an
extended retinacular posterior flap. Aims
Patients and Methods
We undertook a retrospective comparative study
of all patients with an unstable slipped capital femoral epiphysis presenting
to a single centre between 1998 and 2011. There were 45 patients
(46 hips; mean age 12.6 years; 9 to 14); 16 hips underwent intracapsular
cuneiform osteotomy and 30 underwent pinning Pinning Non-emergency intracapsular osteotomy may have a protective effect
on the epiphyseal vasculature and should be undertaken with a delay
of at least two weeks. The place of emergency pinning Cite this article:
We reviewed the long-term results of the treatment of slipped upper femoral epiphysis (SUFE) using realignment procedures in 36 patients (37 hips) at an average follow-up of 33.8 years (26 to 42). There were serious short-term complications in seven of the 22 hips treated by subcapital osteotomy, three of the 11 hips treated by intertrochanteric osteotomy and three of the four hips treated by manipulative reduction. At re-examination, the clinical and radiological results were excellent or good in 41% of the hips treated by subcapital osteotomy, in 36% treated by intertrochanteric osteotomy and in none treated by manipulative reduction. In all, seven hips (19%) had had arthrodesis or total hip replacement. The natural history of SUFE was probably not improved by any of the treatments used in our study. We therefore discourage the use of subcapital and intertrochanteric osteotomy as well as manipulative reduction in the primary treatment of chronic SUFE.
Several authors have reported complications from screw removal after treatment of slipped upper femoral epiphysis by single screw fixation, and have attributed these to poor screw design. We have developed a simple and reliable method of screw removal which uses a cannulated 8.0 mm end-threaded cancellous screw (Smith &
Nephew Richards Medical, Memphis, Tennessee) and a specially designed cannulated trephine. The method has been successful, with minimal complications, and a limited surgical exposure.
