2.Take the treatment of hip fracture in the elderly as an opportunity to explore a standardized procedure suitable for the national population The standardized procedure for the treatment of a certain disease, also known as treatment guidelines, is often the result of multicenter, large sample, randomized controlled prospective studies or evidence-based medicine, and is one of the signs of a country’s medical maturity. Guidelines for the treatment of hip fractures were proposed in Australia as early as 2010 and are continuously updated based on clinical practice. Although the number of elderly hip fracture patients in China is huge, it is still in its infancy in terms of treatment guidelines. Nevertheless, some domestic experts have been keenly aware of the seriousness of the problem and have taken the lead in exploring it. Professor Changqing Zhang has pioneered the establishment of a green channel for geriatric hip fractures, which focuses on “emergency assessment and access, anesthesia consultation and preparation, postoperative monitoring and rehabilitation”, aiming to enable geriatric hip fracture patients >65 years old to receive surgery within 48 h after injury through the green channel. Marcantonio et al. established a proactive geriatric consultation team, focusing on the management of perioperative problems such as water-electrolyte imbalance and pain in elderly patients with hip fractures; early removal of the urinary catheter, encouraging patients to move to the floor early, prophylactic administration of low-dose haloperidol, and other measures to prevent delirium. Lundstrom et al. established a specialized geriatric orthopedic ward to provide specialized care for patients, reducing the incidence of comorbidities such as bedsores, urinary tract infections, and delirium. Inspired by this medical model, my hospital was the first in China to establish a geriatric orthopedic ward in 2012 and proposed a multidisciplinary medical and nursing model for the treatment of geriatric fractures, which means that “each patient will be assessed by a multidisciplinary team upon admission (admission assessment) for a comprehensive assessment of the patient’s general and specialized conditions, and within 24 hours, a patient-specific A comprehensive and individualized treatment and rehabilitation program is formulated for each patient within 24 hours, and adjusted according to the changes in the patient’s condition. Preoperative anesthesia protocols (preoperative assessment) are developed in collaboration with anesthesiologists, and targeted functional training begins the day after surgery to encourage early bed release.” This multidisciplinary medical and nursing care model is manifested in (1) strengthening nutritional support for elderly hip fracture patients in the perioperative period; (2) paying attention to the in and out volume when rehydrating fluids, which must be “more out than in” to avoid heart failure caused by rapid rehydration and rehydration; (3) paying attention to maintaining water-electrolyte balance; (4) surgery should be strived for within 24 ～(4) Surgery should be performed within 24 to 36 h after injury, and the operation should be simple and minimally invasive; (5) Encourage early functional exercises after surgery, and start functional exercises such as continuous passive motion (CPM) and plantar pump when patients return to the ward, including sitting up, lung functional exercises, and isometric contraction of lower limb muscles on the first day after surgery. The second postoperative day includes bed sitting, swinging exercises of both lower limbs, and gradual straight leg raising. Day 3 includes non-restrictive weight-bearing of both lower limbs in the case of standing and using assistive devices (walkers, etc.), with gradual transition to lifting and walking, and a fall prevention program also as part of the early postoperative functional exercise; (6) postoperative application of low-molecular heparin to prevent deep vein thrombosis, which can be routinely given 6,000 U/time, 2 times/d. However, for patients with routine anticoagulation after heart valve replacement, it is necessary to joint hematology and cardiovascular medicine consultation to find the best anticoagulation program; (7) most patients prefer to use regional block anesthesia to reduce postoperative complications and general anesthesia if necessary, and patients with intubated general anesthesia often have more sputum or difficulty in sputum evacuation after surgery. Over the past year since the establishment of the Department of Geriatric Orthopedics, Song Zhaohui et al. treated a total of 297 cases of geriatric intertrochanteric fractures, which were compared with 136 patients treated in the general orthopedic ward in the previous year. It was found that the experimental group had a significantly higher rate of comorbidity detection, a significant decrease in perioperative complications, and a shorter bed rest time. This suggests that it is important to establish a specialized geriatric orthopedic ward in a large orthopedic hospital and to explore the standardization of hip fracture treatment in the elderly. Yang Zongyou et al. introduced the current status and shortcomings of femoral neck fracture treatment in more detail, which is not only helpful for postgraduates with femoral neck fracture diagnosis and treatment as their subject, but also has good reference value for clinical orthopedic surgeons. Dr. Liu Bo’s Pipkin IV fracture treatment strategy and efficacy analysis does not strictly belong to the category of hip fracture, but his collection of 35 patients with Pipkin IV fracture is rare and valuable, and the follow-up period is long, up to 84 months. The relationship between the choice of different surgical approaches and the prognosis provides us with a high reference value for the future management of this type of difficult fracture. 3 .Outlook In the future, the core of the development of geriatric hip fracture and even the whole geriatric orthopedics in China is to establish a multidisciplinary synergistic treatment center, and the establishment of a specialized orthopedic ward for geriatric trauma is undoubtedly the best realized form to realize this multidisciplinary cooperation. In the near future, there will even be specialized orthopedic hospitals for the elderly to meet the trend of rapid aging in China. In addition, the concept of “green channel for geriatric fracture” has positive significance in guiding the emergency management of geriatric fracture and is one of the future development trends. In conclusion, we firmly believe that through the efforts of Chinese orthopaedic surgeons, we will realize the “integrated medical care and rehabilitation treatment” for geriatric fracture patients and explore the geriatric fracture treatment guidelines suitable for Chinese conditions, so that we can have our own voice in the world orthopaedic stage.
