Aims

To identify the incidence and risk factors for five-year same-site recurrent disc herniation (sRDH) after primary single-level lumbar discectomy. Secondary outcome was the incidence and risk factors for five-year sRDH reoperation.

Methods

A retrospective study was conducted using prospectively collected data and patient-reported outcome measures, including the Oswestry Disability Index (ODI), between 2008 and 2019. Postoperative sRDH was identified from clinical notes and the centre’s MRI database, with all imaging providers in the region checked for missing events. The Kaplan-Meier method was used to calculate five-year sRDH incidence. Cox proportional hazards model was used to identify independent variables predictive of sRDH, with any variable not significant at the p < 0.1 level removed. Hazard ratios (HRs) were calculated with 95% confidence intervals (CIs).

PURPOSE OF STUDY

Periprosthetic fractures after total knee arthroplasty is a potentially serious and challenging complication and the incidence is continuously rising. The purpose of this study was to analyse the prevalence and analyse effectiveness of the various treatment methods for management of periprosthetic fracture of the distal femur after total knee arthroplasty, and to determine the clinical and radiographic results of patients following surgical treatment of these injuries.

METHODS

We reviewed all patients with periprosthetic fractures after total knee arthroplasty treated surgically between 2003 and 2008 from the prospective hospital database. Medical and radiographic records were reviewed for patient characteristics, fracture characteristics, implant details, healing, and complications.

Antero-posterior and lateral radiographs were reviewed at the time of admission, post-operatively and at follow up visits. Fractures were classified according to the Lewis and Rorabeck, Orthopaedic Trauma Association and the methods of Su and DeWal.

Purpose: The management of radicular pain due to lumbar or sacral nerve root compromise remains controversial. Caudal epidural steroid injections are widely employed although there is little hard evidence to confirm their efficacy. This empirical treatment still remains a matter of personal choice and experience. To investigate the clinical effectiveness of caudal epidural steroid injections (CESIs) in the treatment of sciatica and to identify potential predictors (clinical subgroups) of response to CESIs.

Method: Prospective study. All patients with corresponding radicular pain received a course of three caudal epidural steroid injections, two weeks apart. All patients reviewed at three months interval in a dedicated epidural follow up clinic and one-year postal and telephonic follow-up. Exhaustive epidural database maintained. VAS scores documented both axial and limb pain for actual and comparative analysis. ODI and HADS were recorded prior to treatment, at three months follow-up and one year. Main outcome measures: The primary outcome measure was the Oswestry Disability Questionnaire (ODQ). The Visual analogue score (VAS) and the Hospital Anxiety and Depression Scores (HADS) were also employed in all cases.

Results: In the largest single series to date, we report on 928 consecutive patients, with three months follow-up and 354 patients with 12 months follow-up. Fifty-eight percent were females, 24% smoked and 4.1% had ongoing litigation due to their pain. The mean age was 56 years with BMI ranging from 17 to 50 (mean=28). Ten (0.6%) patients required subsequent surgical intervention due to disc herniation. The mean VAS, ODI and HADS improved significantly at three months and one-year results were encouraging.

Conclusion: Significant improvement in both axial and limb pain in the short and intermediate terms achieved facilitating onward referral for physical therapy. Subgroups predicting poor outcome are identified. Positive primary care feedback encourages further recruitment.
