To investigate the effectiveness of T-locking plate in treating medial clavicle fracture so as to find out a therapy with safety and stabil ity. Methods Between October 2006 and January 2009, 13 patients with medial clavicle fracture were treated with open reduction and T-locking plate fixation. There were 9 males and 4 females, aged 18-68 years (mean, 47 years), including 7 cases of traffic accident injury, 4 cases of fall ing injury from height, and 2 cases of heavy object hit injury. The locations were left side in 5 cases and right side in 8 cases. All cases were closed fracture. The disease duration was 1 hour to 14 days. Results All incisions healed by first intention after operation. The X-ray films showed good reduction of fracture and internal fixation. All the 13 patients were followed up 12-18 months (mean, 15 months). The average fracture heal ing duration was 8 weeks (range, 6-12 weeks). No compl ication of infection, nerve or blood vessel injury, hemopneumothorax, or internal fixation loosening or failure occurred. The anatomical medial clavicle structure as well asappearances and functions were restored. According to Rockwood’s score method, the results were excellent in 11 cases and good in 2 cases. Conclusion The internal fixation of T-locking plate in treating medial clavicle fracture has the advantages of good stabil ity and low risk. Besides, the patients can do functional exercises early and the shoulder joint function can be improved in great degree.
Objective To investigate the necessity of coracoclavicular ligament reconstruction in the treatment of unstable distal clavicular fracture with locking plate. Methods We searched PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang database and VIP database for all the articles about the treatment of unstable distal clavicular fractures using locking plate combined with coracoclavicular ligament reconstruction or locking plate alone from the establishment of databases to November 30th, 2022. According to the inclusion and exclusion criteria, we selected the documents that met the requirements of this paper, and extracted the effective data after evaluating the quality of the documents, including the Constant-Murley score, coracoclavicular distance, fracture healing time, complication rate, operative time, intraoperative blood loss, incision length and the Visual Analogue Scale score of postoperative pain. RevMan 5.4 software was used for meta-analysis. Results A total of 11 retrospective cohort studies were included, and the overall quality of the literature was high. A total of 421 cases were included in this study, including 209 cases in the locking plate combined with coracoclavicular ligament reconstruction group and 212 cases in the locking plate group. The results of meta-analysis showed that locking plate combined with coracoclavicular ligament reconstruction in the treatment of unstable distal clavicular fractures was superior to locking plate alone in the Constant-Murley score [mean difference (MD)=7.35, 95% confidence interval (CI) (2.84, 11.87), P=0.001], coracoclavicular distance [MD=–1.22 mm, 95%CI (–1.92, –0.53) mm, P=0.0006], fracture healing time [MD=–2.76 weeks, 95%CI (–4.74, –0.79) weeks, P=0.006] and complication rate [odds ratio=0.31, 95%CI (0.14, 0.68), P=0.004], but the former had longer operative time [MD=9.27 min, 95%CI (4.53, 14.01) min, P=0.0001]. There was no significant difference in the intraoperative blood loss [MD=3.31 mL, 95%CI (–17.01, 23.63) mL, P=0.75], incision length [MD=0.30 cm, 95%CI (–0.11, 0.71) cm, P=0.15], or Visual Analogue Scale score of postoperative pain [MD=–0.26, 95%CI (–0.79, 0.27), P=0.33]. Conclusions Although the reconstruction of the coracoclavicular ligament increases the time of surgery, locking plate combined with coracoclavicular ligament reconstruction in the treatment of unstable distal clavicular fractures is significantly better than locking plate alone in terms of reduction quality, shoulder function recovery, fracture healing time, and the incidence of complications, without significant intraoperative bleeding, prolonged incision or postoperative pain.
Objective To investigate the effectiveness of tunnel osteogenesis technique combined with locking plate in the treatment of aseptic non-hypertrophic nonunion of femoral shaft. MethodsThe clinical data of 23 cases of aseptic non-hypertrophic nonunion of femoral shaft treated with tunnel osteogenesis technique combined with locking plate between January 2017 and December 2020 were retrospectively analysed. There were 17 males and 6 females with an average age of 41.4 years (range, 22-72 years). There were 22 cases of closed fracture and 1 case of open fracture. The types of internal fixation at admission included intramedullary nail in 14 cases and steel plate in 9 cases. The number of nonunion operations received in the past was 0 to 1; the duration of nonunion was 6-60 months, with an average of 20.1 months. Among them, there were 17 cases of aseptic atrophic nonunion of the femoral shaft and 6 cases of dystrophic nonunion. Twenty-two cases were fixed with 90° double plates and 1 case with lateral single plate. The operation time, theoretical blood loss, hospitalization stay, nonunion healing, and postoperative complications were recorded. Harris hip function score, Lysholm knee function score, lower extremity function scale (LEFS), and short-form 36 health survey scale (SF-36) were used at last follow-up to evaluate hip and knee functions. Visual analogue scale (VAS) score was used to evaluate the relief of pain at 1 day after operation and at last follow-up. ResultsThe average operation time was 190.4 minutes, the average theoretical blood loss was 1 458.4 mL, and the average hospitalization stay was 8.2 days. All the 23 patients were followed up 9-26 months, with an average of 18.2 months. The healing time of nonunion in 22 patients was 3-12 months, with an average of 5.6 months. There were 8 cases of limb pain, 8 cases of claudication, 6 cases of limitation of knee joint movement, and 2 cases of limitation of hip joint movement. At last follow-up, the imaging of 1 patient showed that the nonunion did not heal, accompanied by pain of the affected limb, lameness, and limitation of knee joint movement. At 1 day after operation, the VAS score of 23 patients was 6.5±1.8, the pain degree was good in 7 cases, moderate in 12 cases, and poor in 4 cases; at last follow-up, the VAS score was 0.9±1.3, the pain degree was excellent in 21 cases and good in 2 cases, which were significantly better than those at 1 day after operation (t=12.234, P<0.001; Z=–5.802, P<0.001). At last follow-up, the average Harris hip function score of 22 patients with nonunion healing was 94.8, and the good rate was 100%; Lysholm knee function score averaged 94.0, and the excellent and good rate was 90.9%; LEFS score averaged 74.6; SF-36 physical functioning score averaged 85.0 and the mental health score averaged 83.6. ConclusionTunnel osteogenesis technique combined with locking plate in the treatment of aseptic non-hypertrophic nonunion of femoral shaft has a high healing rate and fewer complications, which can effectively relieve pain and improve lower limb function and quality of patients’ life.
Objective
To evaluate the effectiveness of bridging fixation with long locking plate for displaced midshaft clavicular fractures.
Methods
Between October 2010 and December 2011, 18 patients with displaced midshaft clavicular fracture were treated with reduction and bridging fixation with 9 or 10 holes locking plate. There were 17 males and 1 female with an average age of 47 years (range, 23-82 years). Fracture was caused by traffic accident in 6 cases, by falling in 10 cases, by crushing in 1 case, and by crashing object in 1 case. All fractures were closed and displaced or shortened (range, 2.1-3.4 cm; mean, 2.62 cm) with angulation deformity. According to Robinson classification criteria, 5 cases were rated as type 2B1 and 13 as type 2B2. The duration from injury to surgery was 5 hours to 19 days (mean, 5 days). The fracture healing time and complication were recorded; the effectiveness evaluation was performed with Constant-Murley score and satisfaction to appearance.
Results
No neurologic or vascular complication occurred with primary healing of incision. All patients were followed up 12-22 months (mean, 14.7 months). The fracture healing time was 9-14 weeks (mean, 11.4 weeks). During follow-up, no loosening or breakage of internal fixator was observed. The Constant-Murley score was 82-98 (mean, 92.4) at last follow-up; the satisfaction rate of appearance was 88.9% (16/18).
Conclusion
Bridging fixation with long locking plate is an effective method for treatment of displaced midshaft clavicular fractures. Preserved blood supply and stable angle are important to fracture healing.
Objective

Methods
Clinical data of 10 patients with multiple rib fractures from June 2016 to January 2017 in the Sixth People’s Hospital Affiliated to Shanghai Jiaotong University were analyzed. There were 6 males and 4 males with an average age of 38.5±9.0 years (range, 30–63 years). All patients underwent emergency treatment, chest CT and ultrasound examination before they admitted to the hospital. According to rib fractures and injuries, patients were given the tunnel-type ORIF of rib fractures with titanium locking plates, the chest tube and negative suction drainage. The patients were followed up over three months.
Results
All patients were cured. There was no complication during follow-up. No wound infection and death occurred. Postoperative three-month follow-up showed that chest pain was significantly relieved without pulmonary atelectasis and pleural effusion or other complications.
Conclusion
Tunnel-type internal fixation of rib fractures with titanium locking plates is effective, which can quickly restore the stability and integrity of the thorax. Surgical procedure is simple and can get fast postoperative recovery to improve the patient's quality of life.
ObjectiveTo summarize the effectiveness of mini locking plate combined with Kirschner wire in treatment of comminuted Jones fracture.MethodsBetween January 2011 and October 2016, 25 cases with comminuted Jones fracture were treated with mini locking plate combined with Kirschner wire. There were 9 males and 16 females with an average age of 31.4 years (range, 16-66 years). The fractures located on the left side in 11 cases and on the right side in 14 cases. The causes of injury included spraining in 21 cases, falling down in 3 cases, and bruise in 1 case. The bone fragment of all cases was more than 3 pieces. The fracture line was mostly Y-shape or T-shape. Twelve of them were combined with other fractures. The time from injury to operation was 1-9 days (mean, 5 days). The mini locking plate and Kirschner wire were removed at 9-12 months postoperatively. At 12 months postoperatively, the pain was evaluated by the visual analogue scale (VAS) score, and the function by the American Orthopaedic Foot & Ankle Society (AOFAS) score.ResultsAll incisions healed by first intention. All cases were followed up 12-36 months with an average of 21.7 months. Fracture union was observed in all patients without complications such as nonunion, delayed union, and malunion. The fracture union time was 8-12 weeks (mean, 9.4 weeks). At 12 months postoperatively, the VAS score was 1.15±0.87; the AOFAS score was 89.45±6.24, and the results were excellent in 14 cases, good in 9 cases, fair in 1 case, and poor in 1 case, with an excellent and good rate of 92%.ConclusionThe procedure of mini locking plate combined with Kirschner wire for comminuted Jones fracture has such advantages as convenient operation, more rigid fixation, high rate of fracture healing, and good functional recovery in foot.
ObjectiveTo investigate the effectiveness difference between bone transport with a locking plate (BTLP) and conventional bone transport with Ilizarov/Orthofix fixators in treatment of tibial defect. MethodsThe clinical data of 60 patients with tibial fractures who met the selection criteria between January 2016 and September 2020 were retrospectively analyzed, and patients were treated with BTLP (BTLP group, n=20), Ilizarov fixator (Ilizarov group, n=23), or Orthofix fixator (Orthofix group, n=17) for bone transport. There was no significant difference in gender, age, cause of injury, time from injury to admission, length of bone defect, tibial fracture typing, and comorbidities between groups (P>0.05). The osteotomy time, the retention time of external fixator, the external fixation index, and the occurrence of postoperative complications were recorded and compared between groups. The bone healing and functional recovery were evaluated by the Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria. Results All patients of 3 groups were followed up 13-45 months, with a mean of 20.4 months. The osteotomy time was significantly shorter in the BTLP group than in the Ilizarov group, and the retention time of external fixator and the external fixation index were significantly lower in the BTLP group than in the Ilizarov and Orthofix groups (P<0.05). Twenty-two fractures healed in the Ilizarov group and 1 case of delayed healing; 16 fractures healed in the Orthofix group and 1 case of delayed healing; 18 fractures healed in the BTLP group and 2 cases of delayed healing. There was no significant difference between groups in fracture healing distribution (P=0.824). After completing bone reconstruction treatment according to ASAMI criteria, the BTLP group had better bone healing than the Orthofix group and better function than the Ilizarov groups, showing significant differences (P<0.05). Postoperative complications occurred in 4 cases (20%) in the BLTP group, 18 cases (78%) in the Ilizarov group, and 12 cases (70%) in the Orthofix group. The incidence of complication in the BTLP group was significantly lower than that in other groups (P<0.05). Conclusion BTLP is safe and effective in the treatment of tibial defects. BTLP has apparent advantages over the conventional bone transport technique in osteotomy time, external fixation index, and lower limb functional recovery.
ObjectiveTo investigate the effectiveness of anatomical locking plate internal fixation combined with coracoclavicular ligament reconstruction in treatment of the Neer type Ⅱb distal clavicle fractures by comparing with the simple anatomical locking plate internal fixation.MethodsThe clinical data of 40 patients with Neer type Ⅱb distal clavicle fractures who met the criteria between February 2013 and January 2017 were analyzed. Eighteen cases were treated with anatomical locking plate internal fixation and coracoclavicular ligament reconstruction by using a suture anchor (reconstruction group), and 22 cases were treated only with anatomical locking plate internal fixation (non-reconstruction group). There was no significant difference in gender, age, injured side, causes of injury, associated injuries, time from injury to operation between 2 groups (P>0.05). The operation time, medical expense, postoperative coracoclavicular distance, Constant-Murley scores of injured side, and complications were recorded and compared between 2 groups.ResultsAll patients were followed up 12-27 months (mean, 16.3 months). One patient in reconstruction group had superficial wound infection. One patient in non-reconstruction group had pullout of screws from the distal fragment and reduction loss at 1 month postoperatively. The operation time and medical expense in reconstruction group significantly increased when compared with those in non-reconstruction group (P<0.05). All fractures in 2 groups achieved bony union at last follow-up. The rate of coracoclavicular distance increase of injured side in non-reconstruction group was significantly higher than that in reconstruction group (t=2.371, P=0.023). The Constant-Murley scores at 1 month, 3 months after operation, and last follow-up were significantly improved when compared with preoperative values in 2 groups (P<0.05), but no significant difference was observed between 2 groups (P>0.05).ConclusionBoth anatomical locking plate internal fixation with and without coracoclavicular ligament reconstruction can achieve good effectiveness for the Neer type Ⅱb distal clavicle fractures. Therefore, the coracoclavicular ligament reconstruction is not necessary, except for comminuted fractures with the length of lateral fragment less than 1 cm or the patients with poor compliance.
ObjectiveTo report a new type of anatomical locking plate for sternocalvicular joint, and investigate its effectiveness in treatment of sternoclavicular joint fracture and dislocation.MethodsA new type of anatomical locking plate for sternoclavicular joint was developed, which accorded with the anatomical features and biomechanical characteristics of Chinese sternoclavicular joint. By adopting the method of clinical randomized controlled study, 32 patients with the sternoclavicular joint fracture and dislocation who met the selection criteria between June 2008 and May 2015 were randomly divided into groups A and B (n=16), and the patients were treated with new anatomic locking plate and distal radial T locking plate internal fixation, respectively. There was no significant difference between 2 groups in gender, age, injured side, body mass index, cause of injury, type of injury, the time from injury to operation, and preoperative Rockwood grading score (P>0.05). The operation time, intraoperative blood loss, incision length, hospitalization time, and postoperative complications in 2 groups were recorded, and the effectiveness was evaluated by Rockwood grading score.ResultsThe operations of 2 groups completed successfully. The operation time, intraoperative blood loss, and hospitalization time in group A were significantly less than those in group B (P<0.05), but there was no significant difference in the incision length between 2 groups (t=0.672, P=0.507). All the patients were followed up 18-30 months (mean, 24 months). In group A, there were 1 case of sternoclavicular joint pain and 2 cases of wound infection; in group B, there were 1 case of sternoclavicular joint pain, 1 case of internal fixation loosening, and 1 case of sternoclavicular joint re-dislocation; there was no significant difference in complication incidence between 2 groups (P=1.000). The Rockwood grading scores at each time point after operation in 2 groups were significantly higher than those before operation. At 1 month after operation, the Rockwood grading score in group A was significantly higher than that in group B (t=2.270, P=0.031); but there was no significant difference in the Rockwood grading scores between the 2 groups at 6 months and at last follow-up (P>0.05). At last follow-up, according to the Rockwood scoring standard, the results of group A were excellent in 13 cases, good in 2 cases, poor in 1 case, the excellent and good rate was 93.75%; the results of group B were excellent in 11 cases, good in 4 cases, poor in 1 case, and the excellent and good rate was 93.75%; there was no significant difference between 2 groups (Z=–0.748, P=0.455).ConclusionThe new type of anatomic locking plate accords with the Chinese anatomical characteristics. It has the advantages of easy operative procedure, less surgical trauma, shorter operation time, less intraoperative blood loss, shorter hospitalization time, and it can achieve better results in the treatment of sternoclavicular joint fracture and dislocation.
Objective To probe into the effectiveness of vertical compression of locking plate combined with hollow screws in the treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures. MethodsThe clinical data of 128 patients with Sanders type Ⅱ and Ⅲ calcaneal fractures who were admitted between March 2019 and April 2022 and met the selection criteria were retrospectively analyzed. Among them, 65 patients were treated with locking plate combined with hollow screw vertical compression (study group), and 63 patients were treated with simple locking plate (control group). There was no significant difference in baseline data between the two groups (P>0.05), such as gender, age, fracture side and Sanders classification, cause of injury, time from injury to operation. The operation time, intraoperative blood loss, hospital stay, and fracture healing time were recorded and compared between the two groups. Before operation and at 12 months after operation, the American Orthopaedic Foot and Ankle Association (AOFAS) score (including total score, pain score, functional score, and alignment score) was used to evaluate the recovery of foot function, and imaging indicators such as calcaneal width, calcaneal height, calcaneal length, B?hler angle, and Gissane angle were measured on X-ray films. ResultsAll patients were followed up 12 months after operation. There was no significant difference in operation time, intraoperative blood loss, hospital stay, and fracture healing time between the two groups (P>0.05). Poor wound healing occurred in 1 case in the study group and 2 cases in the control group. At 12 months after operation, there was no significant difference between the two groups in the pre- and post-operative difference of calcaneal length, calcaneal height, Gissane angle, and B?hler angle (P>0.05). However, the pre- and post-operative difference in calcaneal width in the study group was significantly higher than that in the control group (P<0.05). The pre- and post-operative difference of AOFAS total score in the study group was significantly higher than that in the control group (P<0.05), and further analysis showed that the pre- and post-operative difference of pain and function scores in the study group were significantly higher than those in the control group (P<0.05), while there was no significant difference in the pre- and post-operative difference of force score between the two groups (P>0.05). ConclusionCompared with simple locking plate treatment, the treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures with vertical compression of locking plate combined with hollow screws can more effectively improve the width of the subtalar calcaneal articular surface, avoid peroneal longus and brevis impingement, reduce pain, and increase the range of motion of the subtalar joint, and the effectiveness is better.
