ABSTRACT

Objective:To investigate the efficacy of Hebert screw internal fixation of osteoporotic distal humeral coronary fractures in the elderly.Methods:A retrospective case series study was conducted to analyze the data of 26 elderly patients with osteoporotic distal humeral coronary fractures treated in Changhai Hospital from December 2011 to December 2018, including 3 males and 23 females aged 56-84 years (mean, 67.8 years). According to Bryan-Morrey classification, there were 7 patients with type I, 11 with type III, and 8 with type IV. All patients received open reduction and internal fixation. Among the 26 patients, 10 patients with simple humeral head fractures were treated with Hebert screw internal fixation, and 16 patients with humeral head fractures combined with humeral epicondyle fracture were treated with Hebert screw combined with humeral condyle miniplate. Operation time and intraoperative bleeding volume were recorded. At last follow-up, elbow range of motion were measured, and Mayo elbow performance score and visual analog scale (VAS) score were assessed. Meantime, complications were observed.Results:A total of 22 patients were followed up for 6-57 months (mean, 31.8 months). Intraoperative bleeding volume was 100 to 245 ml (mean, 126 ml) and operation time was 60 to 195 minutes (mean, 85 minutes). At last follow-up, the elbow joint flexion was (117.3±4.2)° and extension was (8.2±2.1)°. Mayo elbow performance score improved from preoperative 16.5 (12.8, 24.0)points to postoperative 85.0 (82.5, 92.3)points ( P<0.05). VAS was increased from preoperative (9.6±0.5)points to (2.3±0.2)points at latest follow-up( P<0.05). Two patients had elbow joint stiffness after operation and recovered after functional exercise. One patient had bone displacement when receiving rehabilitation care, which did not affect the function, and hence no further treatment was given. All patients had no infection or skin and soft tissue complications after surgery. Conclusions:For osteoporotic distal humeral coronary fractures in the elderly, Hebert screw internal fixation is effective in facilitating function recovery and relieving pain. When the fracture is combined with lateral humeral condyle fracture, additional plate fixation can be used for rigid stabilization.

ABSTRACT

Objective To explore the effect of primary exchange reamed nailing (ERN) and augmentation compression plating (ACP) combined with autogenous bone grafting (ABG) on health-related quality of life in patients with dystrophic or atrophic nonunion of femoral shaft after intramedullary nailing. Methods The study used a prospective study method. Sixty- two patients with femoral shaft nonunion after intramedullary nailing from August 2010 to October 2016 were selected, and the patients were divided into ERN group (group A, 32 cases) and ACP group (group B, 30 cases) by random digits table method. In group A, isthmus nonunion was in 18 cases (56.2%), and non-isthmus nonunion in 14 cases (43.8%); in group B, isthmus nonunion was in 16 cases (53.3%), and non-isthmus nonunion in 14 cases (46.7% ). The health- related quality of life was compared between 2 groups, including physical component summary (PCS) and mental component summary (MCS) in the- 12- item short form health survey (SF- 12), brief pain inventory- severity (BPI- S) and brief pain inventory- interference (BPI- I). Results Fifty-four patients were followed-up for more than 1 year, and the mean follow-up time was 18.3 (13 to 37) months. All patients successfully achieved bone union, and the mean time was 5.8 (4 to 8) months. Significant improvements in terms of SF-12 PCS and SF-12 MCS score were noted after operation for patients with isthmus nonunion in both groups (t=3.148, 2.156, 2.456 and 2.559; P < 0.05), but there were no significant differences before and after operation in group A with non-isthmus nonunion (P >0.05). At the last follow-up, SF-12 PCS and SF-12 MCS in group B were significantly improved compared with those in group A: (45.2 ± 5.8) scores vs. (33.6 ± 4.7) scores and (48.8 ± 6.5) scores vs. (39.4 ± 5.6) scores, and there were statistical difference (P<0.05); SF-12 BPI-S and BPI-I showed obvious relief: (4.6 ± 2.1) scores vs. (6.2 ± 2.5) scores and (5.2 ± 1.9) scores vs. (6.8 ± 2.7) scores, and there were statistical differences (P<0.05); however there were no statistical difference in SF-12 PCS, SF-12 MCS, BPI-S and BPI- I between 2 groups (P>0.05). Conclusions Compared with ERN combined with ABG, ACP combined with ABG can significantly improve the quality of life in patients with dystrophic or atrophic nonunion of femoral shaft after intramedullary nailing. It has greater advantage on the improvement of health-related quality of life, especially for patients with non-isthmus nonunion.

ABSTRACT

Objective To analyze the related risk factors of re-nonunion after primary revision for femoral shaft nonunion subsequent to failed intramedullary nailing. Methods A retrospective study was performed in 61 patients with femoral shaft nonunion subsequent to failed intramedullary nailing from June 2008 to June.All patients were divided into re-nonunion group(22 cases)and non-re-nonunion group (39 cases) according to diagnostic criteria of bone re-nonunion. Univariate analysis was used to analyze 14 factors that may lead to the occurrence of re-nonunion after revision for femoral shaft nonunion subsequent to failed intramedullary nailing including age, gender, body mass index (BMI), smoking, alcohol abuse, injury reason, fracture types, intramedullary nail types, locking screws technology for intramedullary nail, bone nonunion sites, bone nonunion time, pathological types of bone nonunion, primary revision methods and autologous bone graft or not, and multi-factor logistic regression analysis was performed on the factors showing a significant difference. Results Univariate analysis showed significant difference in smoking (χ2= 6.564, P = 0.036), BMI (χ2= 6.783, P = 0.021), bone nonunion sites(χ2=7.316,P=0.011),primary revision methods(χ2=8.069,P=0.003)and autologous bone graft or not(χ 2=6.668,P=0.027).Logistic regression analysis showed that primary revision methods(OR=1.027,95% CI 0.028-0.463,P<0.05)and autologous bone graft or not(OR=1.024,95% CI 0.006-0.363, P < 0.05) were independent risk factors for re-nonunion after revision of femoral shaft nonunion subsequent to failed intramedullary nailing. Conclusions Primary revision methods and autologous bone graft or not are independent risk factors for re-nonunion after revision of femoral shaft nonunion subsequent to failed intramedullary nailing.By strictly controlling the surgical indications and combining with autogenous bone grafting,it is possible to reduce the occurrence of nonunion after primary revision of the femoral shaft nonunion subsequent to failed intramedullary nailing.

ABSTRACT

BACKGROUND:Lisfranc injury is a concealed or low-energy damage in the athletic population. The optimal treatment strategies for Lisfranc injury in the athletes, especial y for high-level or professional athletes, remain controversial. Improvement and development in treatment for Lisfranc injury are ongoing. OBJECTIVE:To summarize the diagnostic and therapeutic strategies and problems in surgery in Lisfranc injuries in the athletic population. METHODS:A computer-based online search was conducted in PubMed and Web of science databases from June 1909 to June 2014 to screen the relevant articles regarding the diagnostic and therapeutic strategies for Lisfranc injury using the key words“Lisfranc, injury, athletes”. The irrelevant and duplicate articles were excluded, and final y 43 articles were reviewed. RESULTS AND CONCLUSION:With the improvement and development in the therapeutic methods for Lisfranc injury, suture button fixation and bioabsorbable screw technology, as novel treatment strategies, have the potential to help restore and/or preserve stability at the tarsometatarsal joints, to avoid the potential risk for internal fixation irritation or the need for removal of hardware after fixation. However, more multi-center, prospective, randomized control ed clinical trials are required for seeking the optimal treatment for Lisfranc injury. For the athletes with Lisfranc injury, the best treatment option, removal timing of internal fixation devices, and the proper postoperative function exercise performed according the conditions of patients are vital for restoring the professional sports level.

ABSTRACT

This study was aimed to observe the curative effect and safety of Danzhi Jiangtang Capsule ( DJC ) combined with atorvastatin on carotid artery intima-media thickness (IMT) in diabetes patients without hyper-tension . A total of 196 diabetes patients without hypertension with incrassate carotid artery IMT were randomly divided into the control group ( 98 cases ) and the treatment group ( 98 cases ) . The conventional diabetes thera-py was given to both groups . The atorvastatin of 20 mg/night was given to the control group . And the atorvas-tatin 20 mg/night added with DJC 9 . 0 g/night were given to the treatment group . The treatment course was 12 months . Carotid artery IMT , carotid atherosclerotic plaque area , FPG , FIns , HOMA-IR , HbA1c , blood lipids , hepatorenal function and etc . were examined before and after the treatment respectively . The results showed that there was a significant positive correlation between carotid artery IMT and FIns , HOMA-IR , HbAlc , LDL-C . After 12-month treatment , the total effectiveness is 85 . 87% in the treatment group . And there was significant difference compared with the control group ( P < 0 . 05 ) . The levels of FPG , FIns , HOMA-IR , HbAlc of the treatment group had no difference compared with the control group . Compared with the control group, TC and LDL-C of the treatment group was obviously decreased (P < 0.05). And HDL-C was significantly increased ( P < 0 . 05 ) . The carotid artery IMT of the treatment group decreased from ( 0 . 11 ±0 . 01 ) cm to ( 0 . 08 ± 0 . 01 ) cm . And compared with the control group , there was statistical significance ( P <0 . 05 ) . The carotid atherosclerotic plaque area of 58 cases in the treatment group decreased from ( 0 . 37 ±0.56) cm2 to (0.21 ± 0.25) cm2. However, there was no statistical significance compared to the control group. There were 5 adverse events in the control group and 9 adverse events in the treatment group . And there was no difference between two groups. It was concluded that DJC combined with atorvastatin can regulate lipid metabolism and reduce carotid artery IMT .

ABSTRACT

Objective To discuss the therapy for acetabular comminuted fractur e combined with compressive defects. Methods From July 1997 to February 2005, 43 cases of comminuted acetabular fracture combined with compressive defect were t reated. 25 cases were obsolete, 16 fresh, and 2 malformed (90 days after injury) . 34 cases were complicated fractures with defects, and 9 simple fractures with defects. The defect volumes ranged from 3 to 9 cm3, averaging 4.5 cm3. They were treated with ATMFS (acetabular tridimensional memory fixation system) to fixate the comminuted bone fragments tridimensionally. The modified acetabular approac h, reduction of acetabular comminuted articular face, anatomical reconstruction of posterior wall of acetabulum with autogenous ilium, autogenous and artificial bone implantation and bone wax isolation were used. The follow-ups lasted from 5 to 86 months, averaging 15.7 months. Results 31 cases achieved anatomical red uction by filling up the compressive defects. 12 cases were treated by anatomica l reconstruction of posterior wall. On average, 5.3 months after operation, the injured hip joint was as good as the healthy one in 40 cases. Ischemia necrosis of femoral head occurred in 1 case, and 2 cases experienced heterotopic ossifica tion with ischemia necrosis of femoral head which led to osseous fusion of hip j oint. Conclusion The new methods for treatment of acetabular fractures with comp ressive defects elevate the reduction rate of acetabulum and femoral head, and a re effective for the functional recovery of hip joint.

ABSTRACT

Epidermal stem cells (ESCs) play a critical role in homeostasis and wound repair of skin tissue. Since ESCs are rare (fewer than 10% in total basal cells population) and lack specific markers,it is difficult to isolate and identify them from keratinocytes. Currently ,isolation of ESCs was achieved mainly by fast adhesion of ESCs to extracelluar matrix or flow cytometry. Several specific markers have been found in recent years for the identification of ESCs.
