The recruitment drive, investment and collaboration within Betsi Cadwaladr University Health Board (BCUHB) sites providing specialist lower limb arthroplasty and trauma service has evolved over last few years with aims to improve patient care and reduce reliance on tertiary referral centres. Through our service-evaluation project, we reviewed the results of treatment provided for periprosthetic femur fractures (PPFFs) presenting to BCUHB sites over last 4 years.

We retrospectively reviewed consecutive PPFFs admitted at three BCUHB sites from January’20 to June’23 with mean follow-up of 20.8 ± 13.2 (8–49) months [n=161; Mean age: 82.2 ± 8.5 (59–101) years, Females:107]. Over the review period we noted a 23% increase in service demand for care of PPFFs. Majority were managed surgically [132/161] [38 revision arthroplasties; 94 ORIFs] at BCUHB sites and two patients were referred to tertiary centre. Average time to surgery was 3.5 days. 90% of the PPFFs were managed successfully with 10% (16/159) having orthopaedic complications needing further intervention. 6.3 (10/159) had medical complications and did not need orthopaedic re-intervention. In our series, 12-month re-operation rate was 6.1% (8/132) and 1-month, 3-month and 1-year mortality rate was 6.3%, 11.3% and 21.4% respectively. These results are comparable to the published results of PPFF management at tertiary centres. Potential cost savings compared to transfer to tertiary centre for PPFF management was £2.31 million. Thus, it is possible to successfully provide adequate care for PPFFs at DGHs and efforts should be made to appropriately equip and adequately staff DGHs, to provide service for local PPFF care.

Periprosthetic joint infections (PJIs) and osteosynthesis-associated infections (OSIs) present significant challenges in trauma and orthopaedic surgery, substantially impacting patient morbidity, mortality, and economic burden. This concern is heightened in patients with pre-existing comorbidities, such as diabetes mellitus, which are not always modifiable at presentation. A novel intraoperative strategy to prevent these infections is the use of Defensive Antibacterial Coating (DAC), a bio-absorbable antibiotic-containing hydrogel applied to implant surfaces at implantation, acting as a physical barrier to prevent infection.

The purpose of this study is to assess the use of a commercially available hydrogel (DAC), highlighting its characteristics that make it suitable for managing PJIs and OSIs in orthopaedics and traumatology. Twenty-five patients who underwent complex orthopaedic procedures with intraoperative application of DAC between March 2022 and April 2023 at a single hospital site were included. Post-operative assessment encompassed clinical, laboratory, and radiographic examinations.

In this study, 25 patients were included, with a mean age of 70 ± 14.77 years and an average ASA grade of 2.46 ± 0.78. The cohort presented an average Charleston Comorbidity score of 5.45 ± 2.24. The procedures included 8 periprosthetic fractures, 8 foot and ankle surgeries, 5 upper limb surgeries, and 4 elective hip and knee surgeries. Follow-up assessments at 6 weeks and 6 months revealed no evidence of PJI or OSI in any patients, nor were any treatments for PJI or OSI required during the interim period.

DAC demonstrated efficacy in preventing infections in high-risk patients undergoing complex orthopaedic procedures. Our findings warrant further investigation into the use of DAC in complex hosts with randomized control trials.

Classifying trochlear dysplasia (TD) is useful to determine the treatment options for patients suffering from patellofemoral instability (PFI). There is no consensus on which classification system is more reliable and reproducible for this purpose to guide clinicians in order to treat PFI. There are also concerns about validity of the Dejour classification (DJC), which is the most widely used classification for TD, having only a fair reliability score.

The Oswestry-Bristol classification (OBC) is a recently proposed system of classification of TD and the authors report a fair-to-good interobserver agreement and good-to-excellent intra-observer agreement in the assessment of TD. The aim of this study was to compare the reliability and reproducibility of these two classifications.

6 assessors (4 consultants and 2 registrars) independently evaluated 100 magnetic resonance axial images of the patella-femoral joint for TD and classified them according to OBC and DJC. These assessments were again repeated by all raters after 4 weeks. The inter and intra-observer reliability scores were calculated using Cohen's kappa and Cronbach's alpha.

Both classifications showed good to excellent interobserver reliability with high alpha scores. The OBC classification showed a substantial intra-observer agreement (mean kappa 0.628)[p<0.005] whereas the DJC showed a moderate agreement (mean kappa 0.572) [p<0.005]. There was no significant difference in the kappa values when comparing the assessments by consultants to those by registrars, in either classification systems.

This large study from a non-founding institute shows both classification systems to be reliable for classifying TD based on magnetic resonance axial images of the patella-femoral joint, with the simple to use OBC having a higher intra-observer reliability score compared to the DJC.
