We tried to evaluate the factors that have an influence on the complications experienced after proximal humeral fractures fixed by locking plates and compare the results from patients having complications with those having no complications. Methods From September 2004 to September 2007, 92 out of 111 displaced proximal humeral fractures treated by open reduction and internal fixation with a locking plate were available for follow-up, with an average time of 15.2 months (12-36 months). The range of motion, Visual Analog Score (VAS) for pain, American Shoulder and Elbow Surgeons' Form (ASES), Constant-Murley, University of California-Los Angles scoring system (UCLA) score, and Simple Shoulder Test (SST) for function evaluation was all recorded at the latest follow-up. The results from patients with complications were evaluated according to the indices listed above and compared with those patients without any complications. Results There were 17 patients with complications, an 18.5% complication rate. Among them, the forward flexion, external rotation and internal rotation were 139.1°±24.3°, 24.1°±19.6°, and up to T10 level on average. The mean VAS score was 1.0±1.1, the ASES score was 82.9±13.8, the Constant 82.1±11.8, the UCLA 28.5±4.1 and the mean SST 9.5 on average. There was no significant difference of complication rate among different age, sex, and injured side, fresh or delayed fracture, combined with other injury or not groups. Compared with the group without complications, patients with complications showed significantly less external rotation and lower Constant-Murley and UCLA functional scores (P 〈0.05). A significant difference in results was seen between patients with complications and those without complications. Conclusion The indication control and appropriate surgical technique were important while performing the locking plate fixation for proximal humeral fractures.展开更多

The mean age was 55.6 years and mean follow-up period was 25.1 months. The scoring system modi-fication for hemiarthroplasty (SSMH) had been adopted for evaluation at the latest follow-up.Results: The pain was obviously relieved in all patients. Fifty patients were painless and 5 patients had slight pain. The mean range of motion was 100°(90°-110°) in abduction, 95°(80°-100°) in forward flexion, 35°(30°-40°) in extemal rotation and internal rotation was confined at L2 level (L1-L3). The mean SSMH score was 27.9 (24-29). Fifty patients (90.1%) were satisfied with the clinical outcome.Conclusions: Shoulder hemiarthroplasty is an effective method to treat complex proximal humeral fractures. The proper selection of patients and prosthesis, good operation skill and enough functional exercise are the key points of successful treatment.展开更多

This is a case report of a PD patient with severe tremors who had proximal humeral fracture. We performed surgery for the left side and conservative treatment for the right side. The patient was a 73-year-old woman who had been diagnosed with PD 10 years prior to presentation. Open reduction internal fixation was conducted for the left proximal humeral fracture. 7 months after the left shoulder fracture, she fell resulting in a right proximal humeral fracture for which she underwent conservative treatment. Although bone union was obtained bilaterally, anterior subluxation occurred in the operated side 9 months postoperative. Screw remove was performed because perforation of the screw was observed in the humeral head and was causing pain. Currently, restriction in range of motion and subluxation may be seen on the side that received conservative treatment, although pain is absent and patient satisfaction is high. On the operated side, there is a marked restriction in range of motion, subluxation, and pain. Our experience revealed that conservative treatment was effective for proximal humeral fractures and that optimal bone union might be obtained even in patients with suboptimal PD control.展开更多

Methods: A distal third humeral shaft fracture model was constructed using fourth-generation sawbones (#3404, composite bone). A total of 24 sawbones with a distal third humeral shaft fracture was randomly divided into three Groups: A, B, and C (n = 8 in each group) for anteromedial, anterolateral, and posterior plating, respectively. All sawbones were subjected to horizontal torsional fatigue tests, horizontal torsional and axial compressive fatigue tests, four-point bending fatigue tests in anteroposterior (AP) and mediolateral (ML) directions and horizontal torsional destructive tests. Results: In the horizontal torsional fatigue tests, the mean torsional angle amplitude in Groups A, B, and C were 6.12°, 6.53°, and 6.81°. In horizontal torsional and axial compressive fatigue tests, the mean torsional angle amplitude in Groups A, B, and C were 5.66°, 5.67°, and 6.36°. The mean plate displacement amplitude was 0.05 mm, 0.08 mm, and 0.10 mm. Group A was smaller than Group C (P 〈 0.05). In AP four-point bending fatigue tests, the mean plate displacement amplitude was 0.16 ram, 0.13 ram, and 0.20 mm. Group B was smaller than Group C (P 〈 0.05). In ML lbur-point bending fatigue tests, the mean plate displacement amplitude were 0.16 mm, 0.19 ram, and 0.17 ram. In horizontal torsional destructive tests, the mean torsional rigidity in Groups A, B, and C was 0.82, 0.75, and 0.76 N·m/deg. The yielding torsional angle was 24.50°, 25.70°, and 23.86°. The mean yielding torque was 18.46, 18.05. and 16.83 N·m, respectively. Conclusions: Anteromedial plating was superior to anterolateral or posterior plating in all mechanical tests except in AP four-point bending fatigue tests compared to the anterolateral plating group. We can suggest that anteromedial plating is a clinically safe and effective way for humeral shaft fractures.展开更多

This study was to evaluate the clinical relationship between the number of medial support screws and the maintenance of fracture reduction after locked plating of proximal humerus fractures. Methods: We retrospectively evaluated 181 patients who had been surgically treated for proximal humeral fractures (PHFs) with a locking plate between September 2007 and June 2013. All cases were then subdivided into one of four groups as follows: 75 patients in the medial cortical support (MCS) group, 26 patients in the medial multiscrew support (MMSS) group, 29 patients in the medial single screw support (MSSS) group, and 51 patients in the 11o medial support (NMS) group. Clinical and radiographic evaluations included the Constant-Murley score (CM), visual analogue scale (VAS), complications, and revision surgeries. The neck-shaft angle (NSA) was measured in a true anteroposterior radiograph immediately postoperation and at final follow-up. One-way analysis of variance or KruskaI-Wallis test was used for statistical analysis of measurement data, and Chi-square test or Fisher's exact test was used for categorical data. Results: The mean postoperative NSAs were 133.46°± 6.01°, 132.39° ± 7.77°. 135.17° ± 10.15°, and 132.41° ± 7.16° in the MCS, MMSS, MSSS, and NMS groups, respectively, and no significant differences were found (F = 1.02, P= 0.387). In the final follow-up, the NSAs were 132.79° ±6.02°, 130.19° ± 9.25°, 131.28° ± 12.85°, and 127.35° ± 8.50° in the MCS, MMSS, MSSS, and NMS groups, respectively (F = 4.40, P = 0.008). There were marked differences in the NSA at the final follow-up between the MCS and NMS groups (P = 0.004). The median (interquartile range [IQR]) NSA losses were 0.0° (0.0-1.0)°, 1.3° (0.0-3.1)°, 1.5° ( 1.0-5.2)°, and 4.0° ( 1.2 -7.1 )° in the MCS, MMSS, MSSS, and NMS groups, respectively (H = 60.66, P 〈 0.001 ). There were marked differences in NSA loss between the MCS and the other three groups (MCS vs. MMSS, Z = 3.16, P = 0.002; MCS vs. MSSS, Z = 4.78, P 〈 0.001; and MCS vs. NMS, Z = 7.34, P 〈 0.001). There was also significantly less NSA loss observed in the MMSS group compared to the NMS group (Z = -3.16, P = 0.002). However, there were no significant differences between the MMSS and MSSS groups (Z = -1.65, P = 0.225) or the MSSS and NMS groups (Z =- 1.21, P = 0.099). The average CM scores were 81.35 ± 9.79, 78.04± 8.97, 72.76 ± 10.98, and 67.33 ± 12.31 points in the MCS, MMSS, MSSS, and NMS groups, respectively (F = 18.68, P 〈 0.001). The rates of excellent and good CM scores were 86.67%, 80.77%, 65.52%, and 43.14% in the MCS, MMSS, MSSS, and NMS groups, respectively ( X^2 = 29.25, P 〈 0.001 ). The median (IQR) VAS scores were 1 (0-2), l (0 2),2 ( 1-3), and 3 (1-5) points in the MCS, MMSS, MSSS, and NMS groups, respectively (H = 27.80, P 〈 0.001). Functional recovery was markedly better and VAS values were lower in the MCS and MMSS groups (for CM scores: MCS vs. MSSS, P 〈 0.001 ; MCS vs. N MS. P 〈 0.001; MMSS vs. MSSS, P= 0.031 and MMSS vs. NMS, P 〈 0.001 and for VAS values: MCS vs. MSSS, Z=3.31, P = 0.001: MCS vs. NMS, Z = 4.64, P 〈 0.001; MMSS vs. MSSS, Z = -2.09, P = 0.037: and MMSS vs. NMS, Z=-3.16, P = 0.003).Conclusions: Medial support screws might help enhance mechanical stability and maintain fracture reduction when used to treat PHFs with medial metaphyseal comminution or malreduction.展开更多

Methods:...Background: Fracture shaft humerus is a major cause of morbidity in patients with upper extremity injuries. The aim of this study was to evaluate the outcome of interlocking nail in humeral shaft fractures. Methods: This study was conducted in the Department of Orthopedic Surgery in SMS and R Sharda University from January 2010 to November 2013. Seventy-eight patients were recruited from emergency and out-patient department having a close fracture of humerus shaft. All patients were operated under general anesthesia and closed reamed interlocking nailing was done. All patients were followed for 9 months. Results: Out of 78 patients, 69 patients underwent union in 90-150 days with a mean of I 10.68 days. Complications found in four patients who had nonunion, and five patients had delayed union, which was treated with bone grafting. All the patients were assessed clinically and radiologically for fracture healing joint movements and implant thilure. The results were excellent in 88.46% and good in 6.41% patients. Complete subjective, functional, and clinical recovery had occurred in almost 100% of the patients. ConcLusions: The results of the present study indicates that in the presence of proper indications, reamed antegrade intramedullary interlocked nailing appears to be a method of choice for internal fixation ofosteoporotic and pathologic fractures.展开更多

文摘The current study is to observe the effect of the locking system strengthened by biomimetic mineralized collagen putty for the treatment of senile proximal humeral osteoporotic fractures.From January 2012 to December 2015,80 cases of senile patients with osteoporotic proximal humeral fractures were randomly divided into an observation group and a control group,each group with a total of 40 cases.The control group was simply treated with locking plate.The observation group was treated with locking plate in combination with biomimetic mineralized collagen putty.The therapeutic effect thereby was observed.The excellent and satisfactory rate was 90%in observation group and was 72.5%in control group.The difference between the two groups was statistically significant(χ^(2)=5.3312,P<0.05).The fracture healing time was 11.8263.62 weeks in observation group and 19.7865.46 weeks in control group.The shoulder joint function score was 89.6368.12 in observation group and 76.9268.18 in control group.There was significant difference between the two groups(t=7.1272;12.7834,P<0.05).The complication rate was 10%in the observation group and 32.5%in the control group(χ^(2)=7.3786,P<0.05).Locking system strengthened by biomimetic mineralized collagen putty has advantages such as accelerating healing of senile proximal humeral fracture,improving the therapeutic effect,reducing the complications.As one of the optimal internal fixation method,it provides a new option for better treatment of senile osteoporotic fracture.
文摘BACKGROUND Radial nerve palsy due to humeral shaft fracture is the most common peripheral nerve injury associated with long bone fractures.An antegrade nailing surgical technique is becoming popular for the fixation of these fractures with minimal invasiveness.We analyzed nerve recovery in patients with humeral shaft fracture and radial nerve palsy treated with humeral nail fixation without nerve exploration.AIM To assess the radial nerve recovery rate and time from humeral shaft fracture with surgical treatment using close nailing.METHODS We retrospectively collected data of patients who underwent undergone surgical nail fixation for humeral shaft fractures between October 1,2016,and March 31,2020.Subsequently,we analyzed the primary or secondary radial nerve palsy recovery rate and radial nerve motor function recovery time.RESULTS The study included 70 patients who underwent surgical treatment for closed-or Gustilo type I open humeral shaft fractures using a nail fixation technique without radial nerve exploration.The patients suffered from primary(n=5)and secondary(n=5)radial nerve palsy.A 100%radial nerve recovery rate was achieved.The mean recovery time was 4.3 mo.CONCLUSION The study results indicate full recovery of radial nerve palsies from humeral shaft fracture using close nailing treatment.Surgeons need not be concerned about the occurrence of permanent nerve palsies.

文摘BACKGROUND Whether operation is superior to non-operation for humeral shaft fracture remains debatable.We hypothesized that operation could decrease the nonunion and reintervention rates and increase the functional outcomes.AIM To compare the clinical efficacy between operative and nonoperative approaches for humeral shaft fractures.METHODS We searched the PubMed,Web of Science,ScienceDirect,and Cochrane databases from 1990 to December 2023 for clinical trials and cohort studies comparing the effects of operative and conservative methods on humeral shaft fractures.Two investigators independently extracted data from the eligible studies,and the other two assessed the methodological quality of each study.The quality of the included studies was assessed using the Cochrane risk bias or Newcastle-Ottawa Scale.The nonunion,reintervention and the overall complications and functional scores were pooled and analyzed using Review Manager software(version 5.3).RESULTS A total of four randomized control trials and 13 cohort studies were included,with 1285 and 1346 patients in the operative and nonoperative groups,respectively.Patients in the operative group were treated with a plate or nail,whereas those in the conservative group were managed with splint or functional bracing.Four studies were assessed as having a high risk of bias,and the other 13 were of a low risk of bias according to the Newcastle-Ottawa Scale or Cochrane risk bias tool.The operative group had a significantly decreased rate of nonunion[odds ratio(OR)0.30;95%CI:0.23 to 0.40,reintervention(OR:0.33;95%CI:0.24 to 0.47),and overall complications(OR:0.62;95%CI:0.49 to 0.78)].The pooled effect of the Disabilities of Arm,Shoulder,and Hand score showed a significant difference at 3[mean difference(MD)-8.26;95%CI:-13.60 to-2.92],6(MD:-6.72;95%CI:-11.34 to-2.10),and 12 months(MD:-2.55;95%CI:-4.36 to-0.74).The pooled effect of Visual Analog Scale scores and the Constant-Murley score did not significantly differ between the two groups.CONCLUSION This systematic review and meta-analysis revealed a trend of rapid functional recovery and decreased rates of nonunion and reintervention after operation for humeral shaft fracture compared to conservative treatment.
文摘There are only a few reports about upper extremity fractures in patients with Parkinson’s disease (PD). This is a case report of a PD patient with severe tremors who had proximal humeral fracture. We performed surgery for the left side and conservative treatment for the right side. The patient was a 73-year-old woman who had been diagnosed with PD 10 years prior to presentation. Open reduction internal fixation was conducted for the left proximal humeral fracture. 7 months after the left shoulder fracture, she fell resulting in a right proximal humeral fracture for which she underwent conservative treatment. Although bone union was obtained bilaterally, anterior subluxation occurred in the operated side 9 months postoperative. Screw remove was performed because perforation of the screw was observed in the humeral head and was causing pain. Currently, restriction in range of motion and subluxation may be seen on the side that received conservative treatment, although pain is absent and patient satisfaction is high. On the operated side, there is a marked restriction in range of motion, subluxation, and pain. Our experience revealed that conservative treatment was effective for proximal humeral fractures and that optimal bone union might be obtained even in patients with suboptimal PD control.
文摘Background: Open reduction and internal fixation with plate and screws are the gold standard for the surgical treatment of humeral shaft fractures, this study was to compare the mechanical properties ofanteromedial, anterolateral, and posterior plating for humeral shaft fractures. Methods: A distal third humeral shaft fracture model was constructed using fourth-generation sawbones (#3404, composite bone). A total of 24 sawbones with a distal third humeral shaft fracture was randomly divided into three Groups: A, B, and C (n = 8 in each group) for anteromedial, anterolateral, and posterior plating, respectively. All sawbones were subjected to horizontal torsional fatigue tests, horizontal torsional and axial compressive fatigue tests, four-point bending fatigue tests in anteroposterior (AP) and mediolateral (ML) directions and horizontal torsional destructive tests. Results: In the horizontal torsional fatigue tests, the mean torsional angle amplitude in Groups A, B, and C were 6.12°, 6.53°, and 6.81°. In horizontal torsional and axial compressive fatigue tests, the mean torsional angle amplitude in Groups A, B, and C were 5.66°, 5.67°, and 6.36°. The mean plate displacement amplitude was 0.05 mm, 0.08 mm, and 0.10 mm. Group A was smaller than Group C (P 〈 0.05). In AP four-point bending fatigue tests, the mean plate displacement amplitude was 0.16 ram, 0.13 ram, and 0.20 mm. Group B was smaller than Group C (P 〈 0.05). In ML lbur-point bending fatigue tests, the mean plate displacement amplitude were 0.16 mm, 0.19 ram, and 0.17 ram. In horizontal torsional destructive tests, the mean torsional rigidity in Groups A, B, and C was 0.82, 0.75, and 0.76 N·m/deg. The yielding torsional angle was 24.50°, 25.70°, and 23.86°. The mean yielding torque was 18.46, 18.05. and 16.83 N·m, respectively. Conclusions: Anteromedial plating was superior to anterolateral or posterior plating in all mechanical tests except in AP four-point bending fatigue tests compared to the anterolateral plating group. We can suggest that anteromedial plating is a clinically safe and effective way for humeral shaft fractures.
文摘Background: Technical aspects of the correct placement of medial support locking screws in the locking plate for proximal humerus fractures remain incompletely understood. This study was to evaluate the clinical relationship between the number of medial support screws and the maintenance of fracture reduction after locked plating of proximal humerus fractures. Methods: We retrospectively evaluated 181 patients who had been surgically treated for proximal humeral fractures (PHFs) with a locking plate between September 2007 and June 2013. All cases were then subdivided into one of four groups as follows: 75 patients in the medial cortical support (MCS) group, 26 patients in the medial multiscrew support (MMSS) group, 29 patients in the medial single screw support (MSSS) group, and 51 patients in the 11o medial support (NMS) group. Clinical and radiographic evaluations included the Constant-Murley score (CM), visual analogue scale (VAS), complications, and revision surgeries. The neck-shaft angle (NSA) was measured in a true anteroposterior radiograph immediately postoperation and at final follow-up. One-way analysis of variance or KruskaI-Wallis test was used for statistical analysis of measurement data, and Chi-square test or Fisher's exact test was used for categorical data. Results: The mean postoperative NSAs were 133.46°± 6.01°, 132.39° ± 7.77°. 135.17° ± 10.15°, and 132.41° ± 7.16° in the MCS, MMSS, MSSS, and NMS groups, respectively, and no significant differences were found (F = 1.02, P= 0.387). In the final follow-up, the NSAs were 132.79° ±6.02°, 130.19° ± 9.25°, 131.28° ± 12.85°, and 127.35° ± 8.50° in the MCS, MMSS, MSSS, and NMS groups, respectively (F = 4.40, P = 0.008). There were marked differences in the NSA at the final follow-up between the MCS and NMS groups (P = 0.004). The median (interquartile range [IQR]) NSA losses were 0.0° (0.0-1.0)°, 1.3° (0.0-3.1)°, 1.5° ( 1.0-5.2)°, and 4.0° ( 1.2 -7.1 )° in the MCS, MMSS, MSSS, and NMS groups, respectively (H = 60.66, P 〈 0.001 ). There were marked differences in NSA loss between the MCS and the other three groups (MCS vs. MMSS, Z = 3.16, P = 0.002; MCS vs. MSSS, Z = 4.78, P 〈 0.001; and MCS vs. NMS, Z = 7.34, P 〈 0.001). There was also significantly less NSA loss observed in the MMSS group compared to the NMS group (Z = -3.16, P = 0.002). However, there were no significant differences between the MMSS and MSSS groups (Z = -1.65, P = 0.225) or the MSSS and NMS groups (Z =- 1.21, P = 0.099). The average CM scores were 81.35 ± 9.79, 78.04± 8.97, 72.76 ± 10.98, and 67.33 ± 12.31 points in the MCS, MMSS, MSSS, and NMS groups, respectively (F = 18.68, P 〈 0.001). The rates of excellent and good CM scores were 86.67%, 80.77%, 65.52%, and 43.14% in the MCS, MMSS, MSSS, and NMS groups, respectively ( X^2 = 29.25, P 〈 0.001 ). The median (IQR) VAS scores were 1 (0-2), l (0 2),2 ( 1-3), and 3 (1-5) points in the MCS, MMSS, MSSS, and NMS groups, respectively (H = 27.80, P 〈 0.001). Functional recovery was markedly better and VAS values were lower in the MCS and MMSS groups (for CM scores: MCS vs. MSSS, P 〈 0.001 ; MCS vs. N MS. P 〈 0.001; MMSS vs. MSSS, P= 0.031 and MMSS vs. NMS, P 〈 0.001 and for VAS values: MCS vs. MSSS, Z=3.31, P = 0.001: MCS vs. NMS, Z = 4.64, P 〈 0.001; MMSS vs. MSSS, Z = -2.09, P = 0.037: and MMSS vs. NMS, Z=-3.16, P = 0.003).Conclusions: Medial support screws might help enhance mechanical stability and maintain fracture reduction when used to treat PHFs with medial metaphyseal comminution or malreduction.
文摘Background: Fracture shaft humerus is a major cause of morbidity in patients with upper extremity injuries. The aim of this study was to evaluate the outcome of interlocking nail in humeral shaft fractures. Methods: This study was conducted in the Department of Orthopedic Surgery in SMS and R Sharda University from January 2010 to November 2013. Seventy-eight patients were recruited from emergency and out-patient department having a close fracture of humerus shaft. All patients were operated under general anesthesia and closed reamed interlocking nailing was done. All patients were followed for 9 months. Results: Out of 78 patients, 69 patients underwent union in 90-150 days with a mean of I 10.68 days. Complications found in four patients who had nonunion, and five patients had delayed union, which was treated with bone grafting. All the patients were assessed clinically and radiologically for fracture healing joint movements and implant thilure. The results were excellent in 88.46% and good in 6.41% patients. Complete subjective, functional, and clinical recovery had occurred in almost 100% of the patients. ConcLusions: The results of the present study indicates that in the presence of proper indications, reamed antegrade intramedullary interlocked nailing appears to be a method of choice for internal fixation ofosteoporotic and pathologic fractures.
