Objective: To analyze the effects of a surgical protocol for infections, nonhealing wound prophylaxis, and analgesia among patients who underwent posterior spinal fusion at a single tertiary-care neurosurgical center.
Methods: This prospective study was conducted in the neurosurgery department of a tertiary-care neurosurgical center and compared a control group of patients who had posterior spinal fusion within 3 months before implementation of a surgical protocol with a study group of patients enrolled within 1 year after protocol implementation. The protocol included a surgical safety checklist, control of modifiable risks associated with surgical site infection, administration of intrawound vancomycin and local analgesia, and standard closure. Postoperative pain, demand for analgesics, and postoperative surgical site infections were assessed among patients before and after the introduction of the protocol.
Results: The control group (n = 35; 30 women; median age, 40 years [interquartile range, 31-54 years]) experienced a higher-than-predicted rate of minor surgical infections and nonhealing wounds (12 patients; 34%). In the study group (n = 113; 74 women; median age, 45 years [interquartile range, 37-54 years]), 11 patients (10%) had minor surgical infections and nonhealing wounds. Introduction of the protocol was associated with a 24% absolute risk reduction for minor surgical site infection and a significant decrease in pain on postoperative days 1 and 2 (P < 0.01 for both). Interpersonal communication improved among specialists involved in patient management.
Conclusions: The protocol was effective in reducing postoperative pain and the rate of surgical site infection among patients with posterior spinal surgeries.

Chronic wounds are a burden to millions of patients and healthcare providers worldwide. With rising incidence and prevalence, there is an urgent need to address non-healing wounds with novel approaches. Impaired wound healing has been shown to be associated with wound microbiota, and multiple bacterial species are known to contribute to delays in closure.

Burn-related neuropathic pain (BRNP) can arise following burn-induced nerve damage, affects approximately 6% of burned human patients and can result in chronic pain. Although widely studied in humans, data on BRNP or its treatment in animals is lacking. A 4-year-old domestic shorthair cat was presented with an infected, non-healing wound suspected to be a caustic burn.

Background: This study aimed to investigate the safety and reliability of using bioabsorbable screws for the fixation of chevron osteotomy in the treatment of hallux valgus (HV) deformity.
Methods: Clinical cases of chevron osteotomy in the treatment of HV deformities in our hospital between December 2018 and August 2022 were retrospectively summarised to compare preoperative imaging indices with those at the final follow-up session, including the hallux valgus angle (HVA), intermetatarsal angle (IMA) and tibial sesamoid position (TSP). The American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scale, short-form health survey questionnaire (SF-36) and European Foot and Ankle Society (EFAS) scale were used to assess therapeutic efficacy.

Chronic wounds, especially non-healing wounds, significantly affect patients' quality of life and raise the costs of therapy. Wound healing is a complicated process involving interdependent stages, which may be impaired and delayed by infections with multi-drug resistant pathogens. Current medical strategies for wound healing, especially the treatment of non-healing wounds, exert limited therapeutic effects, thus become a dramatic challenge for modern medicine.

Calciphylaxis is a rare and potentially fatal condition involving chronic, nonhealing wounds caused by microvascular calcification. There is currently no approved treatment for calciphylaxis, contributing to its devastating impacts on quality of life. In this case series, the authors highlight instances of potentially misdiagnosed calciphylaxis in a cohort of patients and emphasize the importance of accurate diagnosis through multidisciplinary management approaches.
