RESUMO
Objective To investigate the clinical outcomes of arthroscopic rotator cuff repair using improved-press-ift double-row technique for patients of large rotator cuff tear.Methods From December 2013 to November 2014, 52 patients (20 males, 32 females) with a full-thickness large rotator cuff tear underwent arthroscopic improved-press-ift double-row repair were retrospectively analyzed. The mean age of the patients was 65.6 years (range 51 to 76 years). The visual analog pain scale scores (VAS), the range of motion (ROM), University of California at Los Angeles (UCLA), and American Shoulder and Elbow Surgeons (ASES) were used for clinical and functional evaluations before surgery and at the time of 6 months after arthroscopy.Results The mean duration of follow-up was 10.9 months (range 6 to 17 months). At the time of 6 months after arthroscopy, the mean subjective pain score (VAS) was (1.6 ± 0.9), the mean active forward flexion was (145.6 ± 10.7)°, whereas the mean external rotation at the side was (30.8 ± 8.5)°. The mean UCLA score improved to (32.3 ± 3.5), the mean ASES score improved to (81.8 ± 8.7). There was significant difference postoperatively (P < 0.05). No re-tear occurred.Conclusion The improved-press-ift DR technique is effective in arthroscopic large rotator cuff repairing. Compared with suture-bridge technique, this technique can decrease operation time, costs, and is much easier to process.
RESUMO
One hundred and twenty patients with senile primary osteoporosis were enrolled in the study from January 2012 to April 2013,including 41 males and 79 females.Patients were randomly assigned to two groups:60 patients in study group were treated with salmon calcitonin combined with zoledronic acid (salmon calcitonin 50 IU i.m,q.d for 7 d,then 100 IU q.i.d for 7 d,followed by zoledronic acid 5 mg i.v gtt/y);60 cases in control group were treated with alendronate (70 mg p.o/wk).Both groups received the same doses of calcium.Visual analogue scale (VAS) scores were assessed before,and 1,6 and 12 months after treatment,12-Item Short-Form Health Survey (SF-12) and bone mineral density (BMD) were assessed before and 12 months after treatment.There were no significant differences in all baseline parameters between two groups (P ＞ 0.05).After 1 month of treatment,the VAS scores of study group was lower than that of the control group (2.1 ± 3.0 vs.4.2 ± 3.1,P ＜ 0.05),however,both groups had similar improvements in VAS scores in 6 and 12 months after the treatment (P ＞0.05).Compared to those before treatment,physical component summary and mental component summary of SF-12 scores after 1 year of treatment were improved significantly in both groups (P ＜ 0.05).Also,BMD was significantly improved after 1 year of treatment in both groups (P ＜ 0.05).The incidence of side effect in study group was lower than that in control group (16％ vs.20％,P ＜0.05).The results indicate that salmon calcitonin combined with zoledronic acid is an effective,safe,reliable and well tolerated therapy for senile primary osteoporosis.The long-term outcomes remain to be determined.
RESUMO
Objective To evaluate the early clinical outcomes of arthroscopic suture-bridge repair of media to large full-thickness rotator cuff tear.Methods One hundred patients that underwent arthroscopic suture-bridge (suture-bridge group,n =50) or single-row repair (single-row suture group,n =50) for media to massive full-thickness rotator cuff tear from June 2010 to June 2014 were enrolled in this study.The patients (63 males and 37 females),aged 58.7 years (range,46 to 75 years),were all available to the follow-up.Thirty-one patients were injured in traffic crashes,30 in falls,27 in strains and 12 with no apparent reasons.Early passive activity was allowed in suture-bridge group,while shoulder abduction was maintained for 6 weeks postoperatively in control group.Clinical and functional outcomes were measured using the visual analogue scale (VAS),range of motion,University of California at Los Angeles (UCLA) score,and American Shoulder and Elbow Surgeons (ASES) score.Results Mean duration of follow-up was 16.7 months (range,8 to 24 months).Prior to the surgery,these measurements were similar between the two groups.After a follow-up of 3 months,the differences were significant in suture-bridge group compared to control group:VAS [(1.7 ± 1.5) points vs (3.9 ± 2.1) points],forward flexion [(168.3 ± 30.2)° vs (120.2 ± 51.6)°],external rotation [(47.0 ± 11.0)° vs (31.8 ± 13.8)°],UCLA score [(31.7±4.2) points vs (18.2±4.8) points],ASES score [(86.2±14.6) points vs (35.9 ±17.7) points] (P ＜0.05).No re-tear occurred after operation.Conclusion Arthroscopic suture-bridge repair of moderate to massive full-thickness rotator cuff tear results in significant improvement of function outcomes and clinical results,indicating a reliable and effective treatment technique.
RESUMO
Objective To compare the clinical outcomes between proximal femoral nail antirotation (PFNA) combined with salmon calcitonin and PFNA only for the treatment of unstable intertrochanteric fractures in elderly patients.Methods From January 2009 to December 2011,120 elderly patients with intertrochanteric fracture were randomly divided into two groups:calcitonin group and control group.Patients in calcitonin group were treated with PFNA combined with salmon calcitonin,while patients in control group were treated with PFNA only.According to Evans-Jensen classification,60 patients in calcitonin group (28 males and 32 females,with an average age of 75.1 years) were divided into 20 cases of type Ⅱ A,32 cases of type Ⅱ B and 8 type Ⅲ.Sixty patients in control group (27 males and 33 females,with an average age of 74.9 years) were divided into 22 cases of type Ⅱ A,32 cases of type Ⅱ B and 6 type Ⅲ.Bone healing was assessed with X-ray and bone mineral density (BMD) was measured by dual energy X-ray absorptiometry.Harris hip and SF-12 score,complications,adverse effect of salmon calcitonin and subsequent fragility fractures were evaluated postoperatively.Results One-hundred and thirteen patients were followed up for at least 2 years.In 6 months after surgery,there were 4 cases of delayed healing in control group.However,all fractures were healed in 12 months after surgery.No significant difference was found between the two groups in BMD preoperatively.The changes in BMD were significantly different between the two groups in 6 months,1 year and 2 years after surgery.No significant difference was found between the two groups in Harris hip and 1-year SF-12 score while the 2-year SF-12 score was significantly different between the two groups.There was 1 patient in calcitonin group who suffered from subsequent fragility fracture in 3 months after surgery,while there was 6 patients in control group during 13 to 23 months postoperatively.Conclusion PFNA combined with salmon calcitonin achieves good effect for the treatment of unstable intertrochanteric fractures in elderly patients.
RESUMO
Objective To evaluate the influence of intravertebral cleft on the clinical effect of percutaneous kyphoplasty (PKP).Methods One-hundred and eighty three patients with OVCFs who underwent PKP (from December 2009 to December 2011) were divided into IVC group and non-IVC group according to their radiographic features.In IVC group,there were 5 males and 39 females,with an average age of 71.6 years (range,56 to 89 years).And in non-IVC group,there were 22 males and 117 females,aged from 51 to 91 years (average,70.2 years).The distributions of fractured vertebra body,bone cement injection volume,bone cement leakage incidence and types,the postoperative height of fractured vertebral body,as well as the visual analogue scale (VAS) and Oswestry disability index (ODI) were compared between the two groups.Results The distributions of fractured vertebra body between two groups were different.Fractured vertebra body in IVC group mainly located from T11 to L2.Fractured vertebra body in non-IVC group located from T11 to L5,and from T7to T9.The bone cement injection volume and leakage incidence had no significant difference between IVC group and non-IVC group (3.4-5.6 ml vs.3.5-5.1 ml; 45.3％ vs.41.9％).However,the types of bone cement leakage were different.In the IVC group,bone cement mainly leaked into perivertebral soft tissues,while in the non-IVC group it mainly leaked along blood vessels.In both groups,the heights of the fractured vertebral bodies were significantly improved,and the restoration of vertebral height in IVC group was more evident than that in the non-IVC group.The postoperative VAS and ODI had no statistical difference between IVC group and non-IVC group (2.8±1.1 vs.2.4±0.7; 29.3％±6.8％ vs.27.6％±6.9％).Conclusion The osteoporotic compression vertebral fracture mainly located in the range from T12 to L2 vertebra.The application of PKP could obtain a very good result in the treatment of OVCF with intravertebral cleft,moreover,the anterior vertebral height can increase remarkablely.
RESUMO
Objective To compare the clinical effect of arthroscopic single-row and suture-bridge double-row fixation of full-thickness rotator cuff tear.Methods A retrospective study was conducted on 40 patients with full-thickness rotator cuff tear treated by single-row and suture-bridge double-row fixation between May 2010 and May 2012.Single-row rotator cuff repair was performed in 18 patients and doublerow repair in 22 patients.The two techniques were compared in aspects of complications,recovery time to daily life,time to achieve satisfaction score,re-tear rate,pre-and post-operative VAS,University of California at Los Angeles Shoulder Scores (UCLA),and American Shoulder and Elbow Surgeons (ASES).Results Mean period of follow-up was 15.6 months (range,13-24 months).Both treatment were effective in improving VAS,UCLA,and ASES,but the differences were insignificant (P ＞ 0.05).Recovery time to daily life,time to achieve satisfaction score,and large rotator cuff re-tear rate were 69.2 ± 16.6)d,(196.4 ±24.6)d,and 4/5 respectively in single-row fixation,with significant differences from (54.1 ± 13.3)d,(165.0 ±20.6)d,and 1/8 in suture-bridge double-row fixation (P ＜0.05).Conclusion Both treatments are effective for rotator cuff reconstruction,but suture-bridge double-row fixation provides earlier recovery to daily life,shorter time to achieve satisfaction score,and lower incidence of large rotator cuff retear.
