RESUMEN
Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
RESUMEN
Objective:To compare the short-term clinical effect of arthroscopic and open reduction and internal fixation with Herbert screws in treatment of Mason type II radial head fractures.Methods:A retrospective case-control study was conducted to analyze the clinical data of 38 patients with unilateral radial head fractures (Mason type II) admitted to Shanghai Zhongye Hospital from January 2017 to December 2018, including 22 males and 16 females, aged from 20 to 65 years [(37.4±12.6)years]. Twenty patients were treated by arthroscopic reduction and internal fixation with Herbert screw (Group A), and eighteen by open reduction and internal fixation with Herbert screw (Group B). The operation time and fracture healing time were recorded. The visual analogue scale (VAS), elbow flexion and extension range, forearm rotation range and Mayo elbow function score were compared between the two groups before and at 1, 3, 6, and 12 months after operation. The results of Mayo elbow performance score (MEPS) and upper limb function assessment using the disabilites of the arm, shoulder, and hand (DASH) score were compared between the two groups. Complications including screw breakage or fracture displacement were also evaluated.Results:All patients were followed up for 12-14 months [(12.3±2.3)months]. There was no significant difference in operation time between the two groups ( P>0.05). The fracture healing time was (8.9±0.6)weeks in Group A and (8.7±0.6)weeks in Group B ( P>0.05). There was no significant difference in VAS between the two groups before operation ( P>0.05). The VAS was (4.8±0.5)points at 1 month after operation in Group A, lower than (6.0±0.7)points in Group B ( P<0.05). There was no significant difference in VAS between Group A and Group B at 3, 6, and 12 months after operation ( P>0.05). There was no significant difference in elbow flexion and extension range between the two groups before operation ( P>0.05). The elbow flexion and extension range in Group A was (110.4±3.8)° and (137.1±4.0)° at 1, 3 months after operation, which was significant greater than (90.6±4.7)° and (125.1±3.5)° in Group B ( P<0.05). There was no significant difference in elbow flexion and extension range between the two groups at 6 and 12 months after operation ( P>0.05). There was no significant difference in the range of forearm rotation between the two groups before operation ( P>0.05). The range of forearm rotation in Group A was (107.1±2.8)° and (138.1±2.9)° at 1, 3 months after operation, significantly greater than (95.5±3.9)°, (121.5±3.0)° in Group B ( P<0.05). There was no significant difference in forearm rotation range between the two groups at 6 and 12 months after surgery ( P>0.05). There was no significant difference in MEPS between the two groups before operation ( P>0.05). The MEPS in Group A was (50.4±3.8)points at 1 month after operation, higher than (40.6±4.7)points in Group B ( P<0.05). There was no significant difference in MEPS between the two groups at 3, 6, and 12 months after operation ( P>0.05). There was no significant difference in DASH score between the two groups before operation ( P>0.05). The DASH score was (57.1±2.8)points at 1 month after surgery in Group A, higher than (42.5±3.9)points in Group B ( P<0.05). The DASH score was not significantly different between the two groups at 3, 6, and 12 months after operation ( P>0.05). There was no screw loosening or fracture after operation, and one patient in each group had fracture displacement ( P>0.05). Conclusion:For Mason type II radial head fractures, arthroscopic Herbert screw fixation has the advantages of less trauma, less pain and faster functional recovery of the affected limb compared with open reduction and Herbert screw fixation.

RESUMEN
BACKGROUND:Mason II type and III type radial head fractures with massive bone are mainly treated by open reduction and metal fixation, but metal implants have to be removed in the second operation, which increased patients’ travail and financial burden. Absorbable screw/rod also can be used to treat radial head fractures, and has its special advantages due to the low price and no second operation. OBJECTIVE:To compare the clinical therapeutic effects of absorbable rod and Herbert screw for the treatment of Mason II or III type radial head fractures. METHODS:A total of 80 patients with Mason II and III type radial head fractures were equal y assigned to experimental and control groups. They received open reduction and internal fixation. The experimental group was treated with absorbable rod and the control group received Herbert screw. RESULTS AND CONCLUSION:A total of 79 patients were fol owed up for averagely 34 months. No significant difference in average operative time, fracture healing time, Broberg and Morrey elbow scores and incidence of complications was detected between the experimental and control groups (P>0.05). However, treatment costs were lower in the experimental group than in the control group (P<0.05). Results indicated that the therapeutic effects between absorbable rod and Herbert screw for Mason II or III type radial head fractures were similar. However, absorbable rod for radial head fractures can avoid the second operation for removal of the implant. Therefore, we recommend absorbable rod in the choice of internal fixation materials.
RESUMEN
BACKGROUND:At present, the methods of treating unstable comminuted radial head fractures contain open reduction and internal fixation and metal prosthesis replacement. There were success cases treated by the two methods, but some shortcomings simultaneously existed. OBJECTIVE:To compare the clinical therapeutic effects of replacement of the radial head with metal prosthesis with open reduction and internal fixation for the treatment of unstable comminuted radial head fractures. METHODS:A prospective randomized control ed analysis was performed in 45 cases of unstable comminuted radial head fractures. These cases received open reduction and internal fixation and metal prosthesis replacement. This study compared the Broberg and Morrey elbow joint function score and the incidence of complications after fixation, and performed statistical analysis. RESULTS AND CONCLUSION:The subjects were fol owed up for 1-5 years, averagely 2.8 years. According to Broberg and Morrey scores, the average score was 90.1 and the incidence of complications was 13.6%in the prosthesis replacement group. The average score was 76.8 and the incidence of complications was 47.9%in the open reduction. Significant differences were visible between the two groups (P<0.01). Compared with the open reduction group, prosthesis replacement for unstable comminuted radial head fractures obtained better joint function and lower incidence of complications.

RESUMEN
BACKGROUND:The therapeutic regimen of intraarticular calcaneal comminuted fractures commonly selects plate and screw fixation. However, for case of posterosuperior calcaneal fracture, the weakness of achil es tendon stretch and plate screw fixation results in difficulty or maintenance of reduction. OBJECTIVE:To investigate the therapeutic effects of open reduction and internal fixation with steel screw and Steinmann pins for comminuted calcaneal intra-articular and posterosuperior fractures. METHODS:From December 2009 to December 2013, forty patients with fractures of comminuted calcaneal posterosuperior fractures were randomly divided into two groups. In the control group, patients were treated by open reduction and internal fixation by plate screw only. In the experimental group, patients were treated by open reduction and internal fixation by combination of plate screw and Steinmann pin. The Gissane and Bohler angles of the calcaneus were measured from lateral radiograph before and 4 weeks after surgery, and the MARYLAND score was assessed at the last fol ow-up. Gissane and Bohler angle and MARYLAND score were compared in each group and among different groups. RESULTS AND CONCLUSION:Al patients were fol owed up for 9-23 months. BOHLER and GISSANE angles were significantly bigger at 4 weeks after surgery compared with pre-treatment in both groups (P<0.05). BOHLER and GISSANE angles were significantly bigger in the experimental group than in the control group at 4 weeks after surgery (P<0.05). During final fol ow-up, the average score by MARYLAND Foot Score was 78 in the experimental group and 67 in control group, with their excellent and good rate of 80%and 73%. The excellent and good rate was significantly higher in the experimental group than in the control group (P<0.05). These data indicated that open reduction and internal fixation with combination of plate screw and Steinmann pin has better efficacy in treatment of the comminuted calcaneal intra-articular and posterosuperior fractures compared with plate and screw fixation alone. Their fixation is firm. Functional exercise can be performed earlier. Postoperative recovery of function of the affected limbs is better than plate and screw fixation alone.

RESUMEN
Clinical pathway (CP), as a standardized approach and clinical management process for disease diagnosing and treating, is being widely used with more relevant publications reported gradually. But different forms of CP reports may prevent the evaluation and spreading of CP. The authors recommend guidelines for evidence-based Chinese medicine CP report, including 18 items which form 5 big sections, by precise item selection and rigorous expert consensus. All these items can embody the principles of Chinese medicine and comply with the requirements of the clinical practice of Chinese medicine. All above are based on synthesizing the published literature systematically and analyzing the current status in this field, also according to the characteristics of Chinese medicine and methodology requirement of evidence-based medicine.

RESUMEN
Osteoporosis is a common disease in the elderly. As studies on its causation and pathogenic mechanism deepened in recent years,there appeared many anti-osteoporotics and many of them had been widely used in clinic. However,none of them was found to be able to completely replace other drugs to achieve satisfactory effect in clinical applications. They all have certain defects. In this paper,three types of drugs including bone resorption inhibitors,bone mineralizers and bone formation accelerators,were analyzed in terms of their mechanisms of action,advances in clinical application as well as their side effects,so as to guide the clinical choice and combination of drugs targeted to avoid serious side effects and to seek for the direction of further study.
