Comparison of joint function and trauma severity after arthroscopic headless compression screw fixation and conventional open reduction and internal fixation treatment of patellar transverse fracture

Objective:To study the differences in joint function and trauma severity after arthroscopic headless compression screw fixation and conventional open reduction and internal fixation treatment of patellar transverse fracture.Methods: 58 patients with patellar transverse fracture who accepted operative treatment in our hospital between August 2012 and December 2015 were collected and divided into open surgery group (n=30) and arthroscopic surgery group (n=28) according to the surgical approach. Before operation and 3 months after operation, the knee joint function of two groups of patients was evaluated respectively;3 d after operation, enzyme-linked immunosorbent assay (ELISA) was used to detect serum pain mediators, stress hormones and other trauma-related indicators.Results:Differences in the knee joint function index levels were not statistically significant between two groups of patients before operation (P>0.05);3 months after operation, the maximal knee joint flexibility and maximal extension levels of arthroscopic surgery group were higher than those of open surgery group (P<0.05);3 d after operation, serum prostaglandin (PGI2), dopamine (DA), neuropeptide Y (NPY), substance P (SP), glucocorticoid (Cor), renin (R), angiotensin 1 (Ang1), angiotensin 2 (Ang2), epinephrine (E), norepinephrine (NE) and aldosterone (ALD) levels of arthroscopic surgery group were significantly lower than those of open surgery group (P<0.05).Conclusions:Arthroscopic headless compression screw fixation can optimize the knee joint function and reduce the surgical trauma in patients with patellar transverse fracture.

A Biomechanical Comparison of Conventional versus an Anatomic Plate and Compression Bolts for Fixation of Intra-articular Calcaneal Fractures

The purpose of this study was to compare the biomechanical stability obtained by using our technique featured an anatomical plate and compression bolts versus that of the conventional anatomic plate and cancellous screws in the fixation of intraarticular calcaneal fractures.Eighteen fresh frozen lower limbs of cadavers were used to create a reproductive Sanders type-Ⅲ calcaneal fracture model by using osteotomy.The calcaneus fractures were randomly selected to be fixed either using our anatomical plate and compression bolts or conventional anatomic plate and cancellous screws.Reduction of fracture was evaluated through X radiographs.Each calcaneus was successively loaded at a frequency of 1 Hz for 1000 cycles through the talus using an increasing axial force 20 N to 200 N and 20 N to 700 N,representing the partial weight bearing and full weight bearing,respectively,and then the specimens were loaded to failure.Data extracted from the mechanical testing machine were recorded and used to test for difference in the results with the Wilcoxon signed rank test.No significant difference was found between our fixation technique and conventional technique in displacement during 20-200 N cyclic loading(P=0.06),while the anatomical plate and compression bolts showed a great lower irreversible deformation during 20-700 N cyclic loading(P=0.008).The load achieved at loss of fixation of the constructs for the two groups had significant difference:anatomic plate and compression bolts at 3839.6±152.4 N and anatomic plate and cancellous screws at 3087.3±58.9 N(P=0.008).There was no significant difference between the ultimate displacements.Our technique featured anatomical plate and compression bolts for calcaneus fracture fixation was demonstrated to provide biomechanical stability as good as or better than the conventional anatomic plate and cancellous screws under the axial loading.The study supports the mechanical viability of using our plate and compression bolts for the fixation of calcaneal fracture.

Objective:To investigate the effect of vertebroplasty combined with pedicle screw fixation in the treatment of senile osteoporotic vertebral compression fractures.Methods:Eighty-one patients with senile osteoporotic vertebral compression fractures were enrolled in our hospital from January 2015 to January 2019.They were randomly divided into a single group(40 cases)and a combined group(41 cases).),a single group was treated with pedicle screw internal fixation,and the combined group was treated with vertebroplasty.The recovery,pain and dysfunction index of the injured vertebrae before and after operation were compared between the two groups.The serum neurological function related indexes before and after operation were compared and the incidence of postoperative adverse events were recorded.Results:There was no significant difference in the recovery of the injured vertebrae between the two groups(P>0.05).The compression ratio,spinal stenosis rate and Cobb angle of the combined group were significantly lower than the single group(P<0.05).On the 3rd postoperative day,there were no significant differences between the two groups in Visual Analogue Scale/Score(VAS)and Oswestry Dability Index(ODI)scores(P>0.05).The VAS and ODI scores of the group were significantly lower than those of the single group(P<0.05).On the 3rd day after surgery,the neuron-specific enolase(NSE)and brain derived neurotrophic factor(brain-derived neurotrophic factor)were used.The levels of BDNF,S100βand Nerve growth factor(NGF)were not significantly different(P>0.05).At 3 months after operation,the level of BDNF in the combined group was significantly higher than that in the single group.The levels of NSE,S100βand NGF were significantly lower than that of the single group.The group(P<0.05);the incidence of adverse events in the combined group was significantly lower than that in the single group(P<0.05).Conclusions:Vertebroplasty combined with pedicle screw fixation for the treatment of senile osteoporotic vertebral compression fracture can effectively improve the recovery of postoperative vertebral body structure,postoperative pain and dysfunction in Jianing patients,improve postoperative neurological function To reduce the incidence of adverse events,with clinical promotion significance.

Pedicle Screw Fixation with Kyphoplasty Decreases the Fracture Risk of the Treated and Adjacent Non-treated Vertebral Bodies:a Finite Element Analysis

Adjacent vertebral fractures are common in patients with osteoporotic vertebral compression fractures（OVCFs） after kyphoplasty.This finite element study was to examine whether short segment pedicle screw fixation（PSF） with kyphoplasty may decrease the fracture risk of the treated and adjacent non-treated vertebrae after kyphoplasty for OVCFs.By simulating cement augmentation with or without short segment pedicle screw fixation（PSF）,two tridimensional,anatomically detailed finite element models of the T10–L2 functional spinal junction were developed.The insertion of pedicle screws into the intact vertebra apparently decreased the stress distribution of the treated vertebra in vertical compression and other load situations.The stress distribution in the bone structures of the intact vertebra adjacent to the intact-screwed vertebra was much less than that in the one adjacent to the treated vertebra.The insertion of pedicle screws into the intact vertebra greatly decreased the maximum displacement of the cortical bones and cancellous bones of the vertebrae.Our results indicated that short segment PSF with kyphoplasty may decrease the fracture risk of the treated and adjacent non-treated vertebrae in the management of OVCFs.

目的观察无头双加压螺钉内固定与传统切开复位内固定治疗外伤性踝关节骨折对踝关节功能的改善作用。方法前瞻性纳入2017年1月~2020年3月我院骨科收治的踝关节骨折病人98例,采用随机数字表法分为研究组和对照组,每组各49例。对照组采用传统切开复位内固定治疗,研究组实施无头双加压螺钉内固定治疗。比较两组围术期指标、AOFAS评分及GQOLI-74评分差异。两组均随访1年,对比两组术后并发症发生情况,分析临床疗效的差异。结果研究组治疗优良率为93.88%,对照组为71.43%(P<0.05)。研究组平均手术时间为(40.94±6.72)分钟、术中出血量为(41.77±8.26)ml、骨折愈合时间为(10.72±1.66)周,对照组分别为(57.93±13.18)分钟、(56.28±12.27)ml和(13.76±2.08)周,两组比较差异有统计学意义(P<0.05)。研究组术后12个月屈(28.19±5.23)°、伸(8.89±1.52)°、旋前(19.09±2.69)°、旋后活动度(16.81±2.83)°,对照组分别为(24.87±4.75)°、(7.63±1.67)°、(17.28±2.45)°及(14.13±2.57)°,两组比较差异有统计学意义(P<0.05),研究组各维度生活质量评分分别为(72.55±8.83)分、(73.65±9.12)分、(68.69±7.01)分和(73.18±9.23)分,对照组分别为(65.12±8.17)分、(68.35±8.73)分、(63.12±6.84)分和(67.22±8.74)分,两组比较差异有统计学意义(P<0.05)。研究组术后并发症发生率为2.04%,对照组为16.33%,研究组VAS评分为(0.83±0.23)分,对照组为(2.14±0.71)分,两组比较差异有统计学意义(P<0.05)。结论无头双加压螺钉内固定治疗疗效显著,可有效促进病人骨折愈合,提升踝关节功能和生活质量评分,且术后并发症较少,安全性好。
