Purpose Our primary objective was to investigate the time to radiological union following linked nail–plate fixation of distal femur “fragility” fractures. Secondary objectives were to evaluate all-cause reoperations, 90-day mortality, rate of blood transfusion and the impact on quality of life. Methods In this retrospective study of all adults (≥ 65 years) with native or periprosthetic distal femur fragility fractures, underwent a linked nail–plate fixation, data were retrieved on fracture classifications, clinical frailty score, blood transfusion, length of hospital stay, 90-day mortality, time to radiological union, overall complication rates and EuroQoL-5D. Results In total, 18 out of 23 patients completed sequential follow-up. Radiological union was observed in 14 patients (median 143 days; range 42–414). Three patients underwent reoperations. There were no implant failures or a subsequent periprosthetic fractures. Ninety-day mortality was 17.4%. Eighteen patients required blood transfusion. The QoL was significantly lower after index surgery (0.875 vs. 0.684; p < 0.01). Conclusion Based on our observation, with short-term follow-up, the linked nail–plate yields optimal stability to allow immediate weight bearing, in a cohort with moderate frailty. It is reproducible, with variable radiological union rates. The concept of “total femoral spanning” reduces the risk of subsequent periprosthetic fractures. The additional intervention has increased the rates of allogenic blood transfusion. There is significant impact on overall QoL, with almost 50% being more dependent in self-care.

Background: Improvements in outcomes following hip and knee revision arthroplasties have been demonstrated following the introduction of specialised orthopaedic services in the form of ‘hub and spoke’ networking models. In light of the COVID-19 pandemic, these networks have undergone some inevitable adaptations. We investigated the impact of recent adaptations on the performance of our regional revision arthroplasty network. Methods: A retrospective review of all referrals that were discussed at our regional revision arthroplasty meeting, over 2 separate phases, was undertaken. Phase 1 included data between March 2018 and April 2019, representing an interval prior to COVID-19 pandemic. Phase-2 included data between September 2020 and March 2021 (during COVID-19 pandemic). Data were collected from East Midland South Orthopaedic Network (EMSSON) database and included data relating to indication and time to revision surgery, surgeon’s proposal plan, network proposal plan, and executed definitive plan. We compared and analysed network performance between 2 phases. Results: In phase 1, 99 cases were discussed in EMSSON meetings, equating to 35.7% of the region’s revision arthroplasty volume, according to the National Joint Registry (NJR) records. Plan alterations were recommended in 48/99 cases (48.5%), of which 41/48 (85.4%) were adhered to. Phase 2 included 98 discussed cases, equating to 81.6% of the region’s revision arthroplasty volume. Plan alterations were recommended in 20/98 cases (20.4%), all of which were adhered to (100%). Adherence to recommended adaptations showed significant improvement ( p < 0.03). Conclusions: Based upon our observations, a greater volume and proportion of revision arthroplasty cases are now being discussed. Adherence to MDT recommendations has significantly improved following the described adaptations. The number of recommended adaptations to management plans have decreased, indicating an educational value of the network. Overall, these findings demonstrate a trend towards NHS England’s target of 100% of revision arthroplasty cases undergoing MDT discussion.

Domestic cat bites are common and are often treated by simple wound care with good outcome. However, delayed presentation may lead to significant morbidity or even mortality. Twenty cases of cat bites to the hand and wrist were retrospectively reviewed between 2014 and 2018. Data included patient demographics, anatomical site of injury, microbiology results, method of treatment and surgical outcome. The subjects were 18 females and two males aged 27–86 years (mean age of 58 years). Eleven patients (Group A) were presented within 48 hours of their injury. Nine patients (Group B) presented later than 48 hours. Of these, 78% (n = 7) underwent multiple operations secondary to septic arthritis, osteomyelitis, necrotising fasciitis and deep collection. Mean length of hospital stay was 3.4 days in Group A, and 9.2 days in Group B, (p < .01). Four patients underwent digital or ray amputations. The index finger was the most common site of injury (45%). Almost 40% of cases had flexor tendon sheath infection of the fingers. Pasteurella species was isolated from 35% of infected wounds. Mean duration of antibiotic treatment and length of hospital stay were significantly longer in Group B (p < .05). Delayed presentation of infected cat bites increased the likelihood of more complicated surgeries such as amputation. Diabetic fingers with established peripheral neuropathy were more likely to undergo amputation. We recommend that any symptomatic cat bites to the upper limb, especially hand and wrist, must be treated promptly, essentially within 48 hours of injury, particularly in immunocompromised population.
