Objective To summarize the method and effectiveness of open reduction and internal fixation in the treatment of 4 cases of bipolar clavicle dislocations. Methods Between June 2017 and June 2022, 4 patients with bipolar clavicle dislocations were admitted. There were 3 males and 1 female. The age ranged from 27 to 63 years, with an average age of 45 years. There were 2 cases of crushing injury of mine car, 1 case of traffic accident injury, and 1 case of heavy object injury. The time from injury to operation was 3-7 days, with an average of 5.0 days. The sternoclavicular joint dislocations were classified as Grade Ⅱ in 1 case and type Ⅲ in 3 cases, and anterior dislocation in 3 cases and posterior dislocation in 1 case. The acromioclavicular joint dislocations were classified as Tossy type Ⅱ in 2 cases and type Ⅲ in 2 cases. After open reduction, the sternoclavicular joint and acromioclavicular joint were fixed with lateral malleolus locking titanium plate and clavicular hook plate, respectively. ResultsAll operations were successfully completed without vascular or nerve injury. All incisions healed by first intention. All patients were followed up 12-18 months, with an average of 14 months. At last follow-up, the shoulder joint functions were rated as excellent in 3 cases and good in 1 case according to Rockwood score. During follow-up, there was no loosening of internal fixator or fracture. The internal fixators were removed in all patients at 5-7 months after operation (mean, 6 months), and no re-dislocation occurred after removal. Conclusion For bipolar clavicle dislocation, open reduction combined with lateral malleolus locking titanium plate fixation of the sternoclavicular joint and clavicle hook plate fixation of the acromioclavicular joint can achieve good effectiveness. It has the advantages of simple operation, high safety, firm fixation, and fewer complications, and the shoulder function recovers well.
ObjectiveTo investigate the effectiveness of open reduction and internal fixation for multiple injuries of superior shoulder suspensory complex (SSSC) with coracoid process fracture.MethodsBetween January 2014 and October 2018, 22 patients with multiple injuries of SSSC with coracoid process fracture were treated by open reduction and internal fixation. There were 16 males and 6 females, aged from 24 to 72 years with an average age of 36.6 years. There were 10 cases of falling injury, 5 cases of traffic accident injury, and 7 cases of falling from height injury. All of them were fresh closed injuries. The time from injury to operation ranged from 2 to 17 days with an average of 6.9 days. Both X-ray film and CT showed the coracoid process fracture complicated with clavicular fracture in 14 cases, acromioclavicular joint dislocation in 12 cases, and acromioclavicular fracture in 5 cases. There were 14 cases of two places of SSSC, 7 cases of three places of SSSC, and 1 case of four places of SSSC.ResultsAll incisions healed in primary stage after operation. All patients were followed up 10-24 months with an average of 14.1 months. X-ray films showed that all fractures healed and the acromioclavicular joint was normal. The healing time ranged from 6 to 12 months, with an average of 6.2 months. No complications such as internal fixation failure and nonunion occurred. According to University of California Los Angeles (UCLA) shoulder scoring system, the shoulder joint function was rated as excellent in 15 cases, good in 5 cases, and poor in 2 cases at last follow-up. The excellent and good rate was 90.9%.ConclusionOpen reduction and internal fixation for treatment of multiple injuries of SSSC with coracoid process fracture is firm and reliable. Combined with active postoperative rehabilitation program intervention, it can accelerate the recovery of shoulder joint function and achieve satisfactory effectiveness.
ObjectiveTo investigate the effectiveness of limited open reduction via “door-shaft method” and internal fixation with locking plate for two- and three-part fractures of the proximal humerus.MethodsThe clinical data of 64 patients with proximal humeral fractures who were admitted between January 2013 and December 2016 and met the selection criteria were retrospectively analyzed. There were 23 males and 41 females, with an average age of 68.0 years (range, 50-89 years). The injuries were caused by falling in 57 cases, traffic accident in 5 cases, and falling from height in 2 cases. The interval between injury and operation was 1-7 days (mean, 2.1 days). According to Neer classification, there were 28 cases of two-part fractures and 36 cases of three-part fractures. According to the angulation direction of the proximal humeral neck shaft angle, there were 21 cases of adduction fractures and 43 cases of abduction fractures. The fractures were treated with limited open reduction via “door-shaft method” and proximal humerus internal locking systems for internal fixation. The operation time, intraoperative blood loss, number of fluoroscopy, hospital stay, and complications were recorded. The fracture healing was reviewed by X-ray film and the healing time was recorded. The shoulder joint function was evaluated by Neer score standard.ResultsThe operation time was 45-127 minutes, with an average of 82.3 minutes. The intraoperative blood loss was 30-125 mL, with an average of 62.7 mL. Intraoperative fluoroscopy was performed 30-69 times, with an average of 37.0 times. The hospital stay was 6-23 days, with an average of 10.3 days. All incisions healed by first intention. All patients were followed up 12-37 months, with an average of 18.3 months. X-ray film re-examination showed that all fractures healed, the healing time was 12-21 weeks, with an average of 14.3 weeks. After operation, 3 cases had shoulder stiffness and 1 case had fracture malunion. At last follow-up, the Neer score of shoulder joint function was 49-97, with an average of 83.1. Among them, 38 cases were excellent, 13 cases were good, 10 cases were fair, and 3 cases were poor. The excellent and good rate was 79.7%. The excellent and good rate of patients with two-part fractures was 82.1% (23/28), and the excellent and good rate of patients with three-part fractures was 77.8% (28/36).ConclusionThe “door-shaft method” not only reduces the difficulty of the Joystick technique in the reduction of proximal humerus fractures, but also provides auxiliary stability. It is used for limited open reduction and internal fixation with locking plate to treat the two- and three-part fractures of the proximal humerus, which can achieve good effectiveness.
Objective To investigate the improved reduction technique for depression fractures of the lateral tibial plateau and its effectiveness. Methods Between January 2008 and December 2010, 48 patients (48 knees) with depression fractures of the lateral tibial plateau (Schatzker II or III fractures) were treated. There were 32 males and 16 females with an average age of 45.8 years (range, 16-79 years). All fractures were fresh closed fractures, which were caused by traffic accident in 27 cases, by falling from height in 5 cases, by crushing in 8 cases, and by sustained falls in 8 cases. According to Schatzker classification, 29 cases were classified as type II and 19 cases as type III. The lateral cortex was cut off to expose the depression and compacted cancellous bone was elevated to reset the articular surface. After reduction, autologous iliac bone graft and locking plate internal fixation were used. Results Healing of incision by first intention was achieved in all patients, and no complication occurred. All patients were followed up 1.7 years on average (range, 1-3 years). At last follow-up, the knee extension was ( — 0.5 ± 0.3)°, and the knee flexion was (136.9 ± 8.8)°. X-ray films showed that the fracture healing time was 52 weeks and no breakage of internal fixation occurred. According to Rasmussen clinical score, the results were excellent in 35 cases, good in 10 cases, and fair in 3 cases. According to Rasmussen radiographical score, the results were excellent in 41 cases, good in 7 cases; there were 41 excellent scores and 7 good scores of articular reduction; all gained good recovery of coronal and sagittal alignment and condylar width. The articular surface collapse was (1.0 ± 0.7) mm at immediate postoperatively and (1.2 ± 0.7) mm at last follow-up, showing no significant difference (t= — 1.42, P=0.20), but significant differences were found when compared with that at preoperation [(12.2 ± 8.0) mm, P lt; 0.05]. Conclusion This improved technique can provide a satisfactory effectiveness of fracture reduction and can avoid loss of reduction. The short-term effectiveness is good, but futher follow-up is necessary to determine the long-term results.
ObjectiveTo explore the effectiveness of modified inferior pedicle technique with inverted T pattern for severe breast hypertrophy.MethodsBetween January 2016 and May 2017, 15 patients of severe breast hypertrophy had undergone breast reduction using inferior pedicle technique with inverted T pattern combined with dermal suspension sling technique. The patients were 20 to 49 years old, with an average age of 31.6 years. Body mass index ranged from 24.9 to 32.5 kg/m2, with an average of 30.8 kg/m2. Among them, 11 cases had a history of childbearing. The degree of breast ptosis was rated as degree Ⅱ in 6 cases and degree Ⅲ in 9 cases. The unilateral breast reduced 615 g on average (range, 480-1 050 g).ResultsThe skin flap necrosis at the " T” trilateral junction occurred in 3 cases, and healed after dressing changes. The incisions of 12 cases healed and no fat liquefaction, hematoma, or seroma occurred. The sensation of nipple and areola declined at early period after operation in 2 cases, and gradually recovered. All patients were followed up 6-18 months (mean, 13 months). The shapes of bilateral breasts and the height and symmetry of nipple-areolar complex were good, and no obvious scar was found. The effectiveness was evaluated by surgeon and showed that there were 12 cases with satisfactory breast shape and 3 cases with unsatisfactory breast shape; 3 cases with obvious scare and 12 cases with insignificant scar; 13 cases with normal nipple sensation and 2 cases with hypoesthesia; 11 cases with symmetric nipples and 4 cases with asymmetric nipples. The effectiveness was evaluated by patients and showed that the satisfactory breast shape in 10 cases, relatively satisfactory breast shape in 4 cases, and unsatisfactory breast shape in 1 case; highly acceptable scar in 9 cases, moderately acceptable scar in 4 cases, and unacceptable scar in 2 cases; overall satisfactory in 10 cases, relatively satisfactory in 4 cases, and unsatisfactory in 1 case, with the overall satisfaction rate of 93.3% (14/15).ConclusionFor severe breast hypertrophy, the modified inferior pedicle technique with inverted T pattern can obtain satisfactory appearance and avoid the mastoptosis.
Objective To investigate the effectiveness of disc reduction and anchorage in treatment of diacapitular condylar fracture with disc displacement. Methods Between June 2019 and June 2021, 20 patients (27 sides) with diacapitular condylar fractures with disc displacement were treated with disc reduction and anchorage combined with internal fixation. There were 15 males and 5 females with a median age of 40 years (range, 8-65 years). The fractures were caused by falling from height in 3 cases, traffic accident in 3 cases, and falling in 14 cases. Among them, there were 13 cases of unilateral fracture and 7 cases of bilateral fractures. Five sides were type A fractures and 22 sides were type B. There were 14 simple diacapitular condylar fractures, 12 diacapitular condylar fractures combined with mandibular chin fractures, and 1 diacapitular condylar fracture combined with mandibular angle fracture. The maximum opening was 5-20 mm (mean, 9.7 mm). The time from injury to operation was 4-20 days, with an average of 11.6 days. The postoperative imaging examination was performed to evaluate the reduction of fracture and disc. The maximum opening at 6 months after operation was recorded, and the clinical dysfunction index (Di) of Helkimo index was used to evaluate the temporomandibular joint function. Results All incisions healed by first intention. All 20 patients were followed up 6-10 months (mean, 8 months). Postoperative imaging examination showed that 27 fractures were well reduced, of which 26 were anatomically reduced and 1 was basically reduced; the reduction of the temporomandibular joint disc was excellent in 25 sides, good in 1 side, and poor in 1 side, and the effective rate of disc reduction and anchorage was 96.3%. The occlusion relationship of the patient was stable and basically reached the pre-injury level, the incision scar was hidden, and the mouth opening significantly improved when compared with the preoperative level. The maximum mouth opening was 32-40 mm (mean, 36.8 mm) at 6 months after operation. Maximum opening was more than 35 mm in 17 cases. At last follow-up, joint function reached Di 0 grade in 8 sides, DiⅠ grade in 18 sides, and DiⅡ grade in 1 side. After operation, 2 cases of opening deviation, 1 case of joint click, and 2 cases of temporary disappearance of frontal striae on affected side occurred, which recovered to normal after symptomatic treatment. ConclusionFor diacapitular condylar fractures with disc displacement, it is necessary to adopt disc reduction and anchorage at the same time of fracture reduction and internal fixation, which can achieve good clinical results.
Objective To introduce a new fluoroscopic method for assessing the quality of medial and lateral joint surface reduction during internal fixation of patellar fractures and to summarize the clinical outcomes of patients treated using this method. Methods A retrospective analysis was conducted on the clinical data of 52 patients with patellar fractures treated between January 2018 and January 2022 who met the inclusion criteria. There were 27 male and 25 female patients, aged 21-75 years, with an average age of 62 years. The types of patellar fractures included 9 transverse fractures, 37 comminuted fractures, and 6 longitudinal fractures. According to the AO/Orthopaedic Trauma Association (AO-OTA)-2018 fracture classification, there were 21 cases of type 34A, 6 cases of type 34B, and 25 cases of type 34C. The time from injury to operation ranged from 1 to 5 days, with an average of 2.3 days. Treatments included internal fixation with hollow screws or hollow screw tension bands, with or without anchor repair. During operation, the medial and lateral joint surfaces of the patella were observed using the tangential fluoroscopic method to assess the smoothness of reduction of the median ridge, lateral joint surface, medial joint surface, and lateral joint edge. Patients were followed up regularly, and X-ray films were taken to observe fracture healing. Knee joint range of motion, Böstman score, and Lysholm score were used to evaluate functional recovery. Results The tangential fluoroscopic method for the medial and lateral joint surfaces of the patella during operation showed satisfactory reduction of the joint surfaces and good positioning of the implants. All patients were followed up 12-16 months, with an average of 13.4 months. During the follow-up, fracture displacement occurred in 1 case and titanium cable breakage in 1 case. All patella fractures healed successfully, with a healing time of 8-16 weeks (mean, 11.4 weeks). At last follow-up, knee joint range of motion ranged from 120° to 140°, with an average of 136°. The Böstman score ranged from 20 to 30, with an average of 28, yielding excellent results in 45 cases and good results in 7 cases. The Lysholm score ranged from 88 to 100, with an average of 93, yielding excellent results in 40 cases and good results in 12 cases. Conclusion The intraoperative application of the tangential fluoroscopic method for the medial and lateral joint surfaces of the patella can quickly determine the fluoroscopic plane of the patella, accurately assess the quality of fracture reduction and the position of internal fixator, thereby improving effectiveness.
ObjectiveTo investigate the effectiveness and advantages of skeletal tractor in closed reduction and proximal femoral nail antirotation (PFNA) internal fixation of intertrochanteric fracture compared with traction table.MethodsThe clinical data of 86 patients with intertrochanteric fractures, who were treated with closed reduction and PFNA internal fixation between October 2016 and March 2018 and met the selection criteria, was retrospectively analysed. Among them, 44 cases were treated with skeletal tractor (trial group) and 42 cases were treated with traction table (control group). There was no significant difference between the two groups in gender, age, cause of injury, fracture side, AO classification, and degree of osteoporosis (P>0.05). The preoperative position time, operation time, intraoperative fluoroscopy times, intraoperative blood loss, fracture healing time, intraoperative and postoperative complications, and postoperative Harris score were compared between the two groups.ResultsThe operation was successfully completed in both groups. Compared with the control group, the patients in the trial group had shorter preoperative position time and operation time, fewer intraoperative fluoroscopy times, and less intraoperative blood loss (P<0.05). The patients were followed up 12-21 months in trial group (mean, 14.2 months) and 12-22 months in control group (mean, 14.3 months). Venous thrombosis of lower extremity occurred in 8 patients (3 cases of trial group and 5 cases of control group) after operation. Internal fixation failure occurred in 5 patients (2 cases of trial group and 3 cases of control group) during 1 year after operation. All fractures healed except for those with internal fixation failure, the fracture healing time was (11.6±2.9) weeks in trial group and (12.4±3.6) weeks in control group; and there was no significant difference between the two groups (t=1.250, P=0.214). At 1 year after operation, Harris score of the trial group was 86.2±5.9 and that of the control group was 84.1±6.1. There was no significant difference between the two groups (t=1.768, P=0.080).ConclusionCompared with traction table, skeletal tractor in closed reduction and PFNA internal fixation of intertrochanteric fracture can significantly shorten the preoperative position time and operation time, reduce the intraoperative fluoroscopy times, improve the operation efficiency, and have similar effectiveness.
ObjectiveTo explore the efficacy and advantages of the lower extremity axial distractor assisted closed reduction and retrograde intramedullary nail internal fixation in the treatment of distal femoral fractures.MethodsThe clinical data of 49 patients with distal femoral fractures treated with retrograde intramedullary nail internal fixation between April 2016 and December 2018 were retrospectively analyzed. According to the different methods of intraoperative reduction, the patients were divided into trial group (29 cases, using lower extremity axial distractor to assist closed reduction) and control group (20 cases, using free-hand retraction reduction). There was no significant difference in general information between the two groups (P>0.05), such as gender, age, side of injury, cause of injury, and fracture classification. The operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, and callus formation time were recorded and compared between the two groups. The function of the affected limb was evaluated according to the Schatzker-Lambert standard at 1 year after operation.ResultsAll patients successfully completed the operation. In the control group, there was 1 case with open reduction and internal fixation, and the rest of the two groups were closed reduction. There was no significant difference in operation time, intraoperative blood loss, and intraoperative fluoroscopy frequency between the two groups (P>0.05). There was no complication such as vascular or nerve injury and iatrogenic fracture, etc. during and after operation, and the incisions healed by first intention. Except for 2 patients in the trial group who were lost to follow-up at 3 months after operation, the rest of the patients were followed up 12-36 months, with an average of 16.0 months. There was no significant difference in the callus formation time between the two groups (t=2.195, P=0.145). During the follow-up, postoperative knee joint stiffness occurred in 1 case in the control group, which improved by strengthening the knee joint function exercise and removing the internal fixator; the rest were not found to be associated with delayed or nonunion fractures, knee stiffness, and internal fixation complication. The function of the affected limb was evaluated according to the Schatzker-Lambert standard at 1 year after operation, the trial group achieved excellent results in 22 cases, good in 4 cases, and fair in 1 case, with an excellent and good rate of 96.3%; in the control group, the results were excellent in 16 cases, good in 3 cases, and fair in 1 case, with an excellent and good rate was 95.0%; showing no significant difference in the excellent and good rate between the two groups (χ2=0.451, P=0.502).ConclusionThe lower extremity axial distractor assisted closed reduction and retrograde intramedullary nailing for the treatment of distal femoral fractures is convenient, which has satisfactory efficacy.
ObjectiveTo compare the effectiveness between open reduction and closed reduction of pediatric subtrochanteric fractures using elastic stable intramedullary nailing (ESIN). MethodsBetween January 2010 and January 2014, 22 children with subtrochanteric fractures were treated by ESIN internal fixation combined with hip cast fixation, and the clinical data were retrospectively reviewed. Closed reduction was used in 12 cases (group A) and miniopen reduction in 10 cases (group B). There was no significant difference in gender, age, sides, fracture causes, type of fracture, complications, and time from injury to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, fracture healing time, and complications were recorded and compared between 2 groups, the limb function was evaluated according to the Flynn et al. outcome score. ResultsThe intraoperative blood loss of group A was significantly less than that of group B, but the operation time of group A was significantly longer than that of group B (P<0.05). All the patients were followed up 12-36 months (mean, 14.9 months). There was no major complications in the other patients of both groups except 1 patient having delayed wound healing in group B. There was no significant difference in fracture healing time between 2 groups (t=-1.006, P=0.327). Inverted angle of 10° and shortened limb of 1.8 cm were observed in 1 case of group A, and sagittal plane angle of 15° and shortened limb of 2 cm in 1 case of group B. There was no abnormal walking and function of hip and knee activity at last follow-up. According to the Flynn et al. outcome score, the results were excellent in 8 cases and good in 4 cases in group A, and were excellent in 6 cases and good in 4 cases in group B, showing no significant difference between 2 groups (χ2=0.041, P=0.956). ConclusionBoth closed and open fracture reduction using ESIN have satisfactory outcomes for treating pediatric subtrochanteric fractures. A mini-open reduction should be selected intraoperatively if closed reduction proves to be difficult.
