The optimal procedure for the treatment of ossification of the posterior longitudinal ligament (OPLL) remains controversial. The aim of this study was to compare the outcome of anterior cervical ossified posterior longitudinal ligament en bloc resection (ACOE) with posterior laminectomy and fusion with bone graft and internal fixation (PTLF) for the surgical management of patients with this condition. Between July 2017 and July 2019, 40 patients with cervical OPLL were equally randomized to undergo surgery with an ACOE or a PTLF. The clinical and radiological results were compared between the two groups.Aims
Methods
Free vascularised fibular grafting has been reported
to be successful for adult patients with osteonecrosis of the femoral
head (ONFH). However, its benefit in teenage patients with post-traumatic
ONFH has not been determined. We evaluated the effectiveness of
free vascularised fibular grafting in the treatment of this condition
in children and adolescents. We retrospectively analysed 28 hips
in 28 patients in whom an osteonecrotic femoral head had been treated
with free vascularised fibular grafting between 2002 and 2008. Their
mean age was 16.3 years (13 to 19). The stage of the disease at
time of surgery, and results of treatment including pre- and post-operative
Harris hip scores, were studied. We defined clinical failure as
conversion to total hip replacement. All patients were followed
up for a mean of four years (2 to 7). The mean Harris hip score
improved from 60.4 (37 to 84) pre-operatively to 94.2 (87 to 100)
at final follow-up. At the latest follow-up we found improved or
unchanged radiographs in all four initially stage II hips and in
23 of 24 stage III or IV hips. Only one hip (stage V) deteriorated.
No patient underwent total hip replacement. Free vascularised fibular grafting is indicated for the treatment
of post-traumatic ONFH in teenage patients.
