Objective To analyze the treatment of the sternoclavicular joint dislocation by clavicular hook plate and investigate its cl inical value to find a theropy with more safety and stabil ity. Methods Between January 2003 and January 2007, 15 patients with sternoclavicular joint dislocation were involved, among whom there were 12 males and 3 females, aged 28-45 years old (34 on average). There were 12 cases of fall ing injury and 3 cases of vehicle accident injury. The course of disease was 1-12 hours. A total of 2 cases were on the left side and 13 were on the right side. There were 14 casesof anterior dislocation and 1 of posterior dislocation. Two patients were compl icated by acromioclavicular joint dislocationwith no pneumothorax, and 2 patients had a l ittle pleural effusion without any special treatment. As to the damage degree,according to the Grade system, there were 2 cases of type II and 13 cases of type III. Results All patients’ incisionsobtained heal ing by first intention after operation. The X-ray films showed that the reduction of joint dislocation and thelocation of internal fixation were good. All the 15 patients were followed up for 6-18 months (14 months on average). All cases were scored by Rockwood after the operation to assess the curative effect, with 12 excellent, 2 good and 1 fair. There was no wound infection, neurovascular injury, hemopneumothorax, internal fixation failure, redislocation or other side injuries. The anatomical structure as well as appearances and functions were restored. Conclusion The fixation of clavicular hook plate in treating ternoclavicular joint dislocation has superiority over other methods with more stabil ity, less risk and small chances of cardiovascular injury. Besides, the patients can do functional exercises early and the shoulder joint function can be improved to the maximal degree.
ObjectiveTo evaluate and compare the effectiveness of double Endobutton technique and suture anchor combined Endobutton plate in the treatment of Tossy type Ⅲ acromioclavicular joint dislocation. MethodsBetween May 2010 and March 2014, a retrospective study was preformed on 56 patients with Tossy type Ⅲ acromioclavicular joint dislocation. The coracoclavicular ligament was reconstructed with double Endobutton technique in 31 cases (Endobutton group), and with suture anchor combined Endobutton plate in 25 cases (Anchor group). There was no significant difference in age, gender, injury causes, injury side, associated injury, medical comorbidities, and disease duration between 2 groups (P>0.05). The operation time, medical device expenses, postoperative complications, preoperative and postoperative Constant-Murley scores, and postoperative Karlsson grading of the injured shoulder were compared between 2 groups. ResultsThe average operation time in Endobutton group was significantly greater than that in Anchor group (t=4.285, P=0.000); there was no significant difference in the medical device expenses between 2 groups (t=1.555, P=0.126). Primary healing of incision was obtained in all patients of 2 groups; no early complications of infection and skin necrosis occurred. All patients were followed up 15.6 months on average (range, 11-35 months). During follow-up, some loss of reduction and ectopic ossification in the coracoclavicular gap were observed in 1 case and 6 cases of Endobutton group, respectively. No recurrence of acromioclavicular joint dislocation, implant fixation loosening and broken, and secondary fractures occurred in the other patients. There was significant difference in the incidence of postoperative complications between 2 groups (P=0.013). Constant-Murley scores of the injured shoulder significantly increased at 9 months after operation when compared with preoperative values in 2 groups (P<0.05), but no significant difference was observed between 2 groups (P>0.05). At last follow-up, there was no significant difference in Karlsson grading between 2 groups (Z=-0.628, P=0.530). ConclusionBoth double Endobutton technique and suture anchor combined Endobutton plate have good effectiveness in the treatment of Tossy type Ⅲ acromioclavicular joint dislocation. But the latter is associated with easier operation, less operation time, and less complications.
Objective To investigate the short-term effectiveness of reconstructive locked plate for treating sternoclavicular joint dislocation. Methods Between February 2008 and February 2012, 11 patients with sternoclavicular joint dislocation were treated with reconstructive locked plate, and the clinical data were retrospectively analyzed. There were 7 males and 4 females, aged 30-55 years (mean, 44 years). The causes of injury included traffic accident in 8 cases and crashing in 3 cases. The disease duration ranged from 2 hours to 11 days (median, 6 days). All patients had anterior dislocation of sternoclavicular joint. According to the Grade system, there were 2 cases of type II and 9 cases of type III. Results All patients obtained healing of incisions by first intention after operation. There was no neurovascular injury. The X-ray films showed that satisfactory reduction of joint dislocation and stable internal fixation were obtained at 2 days after operation. All patients were followed up 9-24 months (mean, 16 months). According to the Rockwood criteria, the score was 10-15 (mean, 13.2); the results were excellent in 9 cases and good in 2 cases, with an excellent and good rate of 100% at 9 months after operation. No internal fixation failure or re-dislocation occurred. All internal fixators were removed at 9-15 months after operation. Both the stability and the functions of the shoulder joint were good. Conclusion The reconstructive locked plate in treating sternoclavicular joint dislocation has the advantages of good stability and satisfactory reduction, and the patients can do functional exercises early and obtain good recovery of the shoulder joint function. The short-term effectiveness is satisfactory.
【Abstract】 Objective To evaluate the early result of tri ple Endobutton technique for reconstructing coracoclavicularligament of chronic complete acromioclavicular joint dislocations. Methods Between January 2009 and June 2010, 14 patients with chronic complete acromioclavicular joint dislocations were treated with tri ple Endobutton technique for reconstructing coracoclavicular ligament. There were 10 males and 4 females with a mean age of 38.5 years (range,26-52 years). Injury was caused by traffic accident in 7 cases,by falling in 5 cases，and by bruise in 2 cases. The average time was 47 days from injury to the operation (range,29-75 days). All patients had pain and activity restriction. The X-ray films showed complete dislocation of acromioclavicular joint. According to Allman’s type, all cases were classified as III degree complete dislocations. Results At postoperation, wound healed by first intention with no early complication of infection or neurovascular injury. All patients were followed up 18.3 months on average (range,13-30 months). Acromioclavicular joint subluxation occurred in 1 patient at 1 week after operation, and no redislocation or other complication occurred in the other patients. American Shoulder and Elbow Surgeons (ASES) score was 90.8 ± 4.1 at last follow-up, showing significant difference when compared with the preoperative score (65.3 ± 4.4) (t= —17.57，P=0.00); Constant-Murley score was 91.7 ± 3.9, showing significant difference when compared with preoperative one (71.5 ± 4.6) (t=—75.02，P=0.00). The definite answer in Simple Shoulder Test (SST) averaged 9.7 (range,7-12). Conclusion The tri ple Endobutton technique for reconstructing coracoclavicular ligament is an effective method in treatment of chronic complete acromioclavicular joint dislocations. The short-term results are satisfactory.

ObjectiveTo investigate the effectiveness of one-stage arthroscopic reconstruction and strict immobilization for 6 weeks for treatment of knee dislocation. MethodBetween August 2010 and May 2013, 22 cases (22 knees) of knee dislocation were treated with one-stage reconstruction and strict immobilization for 6 weeks. There were 15 males and 7 females, aged 21-54 years (mean, 31.5 years). The left knee and right knee were involved in 8 cases and 14 cases respectively. The disease causes were traffic accident in 12 cases, falling from height in 6 cases, and sports injury in 4 cases. The time between injury and operation was less than 2 weeks in 6 cases, 2-3 weeks in 10 cases, and more than 3 weeks in 6 cases. The results of anterior drawer test, posterior drawer test, and Lachman test were positive in all patients. The posterior displacement of the tibia was more than 10 mm. The results of valgus stress test and varus stress test were positive in 13 cases and 11 cases respectively. The preoperative knee range of motion was (58.2±28.4) °, Lysholm score was 39.7±4.6. All patients had anterior cruciate ligament rupture and posterior cruciate ligament rupture; combined injuries included medial collateral ligament rupture in 11 cases, lateral collateral ligament rupture in 9 cases, both medial and lateral collateral ligament rupture in 2 cases, femoral condylar avulsion fracture in 2 cases, and meniscus injury in 7 cases. No nerve or blood vessel injury was observed. ResultsAll cases obtained primary healing of incision without infection. All the patients were followed up 12-48 months (mean, 27.8 months). At 12 months after operation, the results of the anterior drawer test, posterior drawer test, Lachman test, valgus stress test, and varus stress test were all negative; the knee range of motion increased was significantly to (121.3±7.9) °(t=30.061, P=0.000) ; Lysholm score was 87.2±6.1, showing significant difference when compared with preoperative score (t=24.642, P=0.000) . ConclusionsA combination of arthroscopic one-stage reconstruction and strict immobilization for treatment of knee dislocation is a safe and effective method, good stability and joint function can be achieved.
Objective To investigate the cl inical efficacy, compl ications and necessity of removing internal fixation in treatment of fresh Tossy type III acromioclavicular joint dislocations and Neer type II distal clavicle fractures with clavicularhook plate. Methods From June 2005 to June 2008, 24 patients with fresh Tossy type III acromioclavicular joint dislocations and 20 patients with fresh Neer type II distal clavicle fractures were treated. There were 32 males and 12 females with an agerange of 18-66 years (38.5 years on average), involving 18 left shoulders and 26 right shoulders. The injury was caused bytraffic accident in 31 cases and by fall ing in 13 cases. The mean time from injury to operation was 4 days (range, 2-8 days). All patients were treated by reduction with clavicular hook plate fixation. The coracoclavicular l igaments were not sutured. The shoulder functions were evaluated according to University of Cal ifornia-Los Angeles (UCLA) score system and analysed before and after removing internal fixation. Results Wound infection occurred in 2 cases 1 week after operation and healed after symptomatic managment, the other incisions healed by first intention. One case accepted hook plate fixation again because of loosening hooking-up 1 week after operation. One case accepted hook plate removal and Kirschner wire fixation because of severe shoulder’s pain on the postoperative third day. Thirty-eight patients were followed up for 8-32 months (18 months on average), there was no plate breakage. Clavicle fractures got bony union after 3-6 months (4.2 months on average). At last followup (before plate removal), according to UCLA shoulder function score system, the results were excellent in 11 cases, good in 22 cases, and fair in 5 cases; the excellent and good rate was 86.8%. Because of shoulder’s pain, plates were removed in 20 patients 3-16 months (10 months on average) after operation. The cases were followed up 3-8 months (5 months on average) after removing plate. No dislocation and fracture occurred again. There was statistically significant difference (P lt; 0.01) in the functional scores of shoulder between before (30.55 ± 4.00) and after removing internal fixation (33.85 ± 1.95). Conclusion Clavicular hook plate fixation is an effective treatment for fresh Tossy type III acromioclavicular joint dislocations and Neer type II distal claviclefractures. Normative operating, correct plate moulding, functional rehabil itation after operation are key factors in preventingcompl ications and reaching good cl inical efficacy. For the patients with postoperative symptoms, the plate should be removed to improve the shoulder’s function.
ObjectiveTo investigate the short-term effectiveness of arthroscopic assisted double Endobutton “8” buckle fixation in the treatment of Rockwood Ⅲ type acute acromioclavicular joint dislocation.MethodsThe clinical data of 12 patients with Rockwood Ⅲ type acute acromioclavicular joint dislocation who were treated with arthroscopic assisted double Endobutton “8” buckle fixation between June 2016 and June 2019 were analyzed retrospectively. There were 8 males and 4 females, with an average age of 47.0 years (range, 36-58 years). There were 4 cases of left shoulder and 8 cases of right shoulder. The causes of injury included traffic accident injury in 7 cases and falling injury in 5 cases. The average time from injury to operation was 5.0 days (range, 3-14 days). Before operation and at last follow-up, the shoulder joint activity was recorded; the improvements of function and pain were evaluated by Constant score and visual analogue scale (VAS) score, respectively; the reduction was evaluated by measuring the coracoid spacing of the affected side on the anteroposterior X-ray film of shoulder joint.ResultsAll 12 cases were followed up 6-36 months, with an average of 20.6 months. All the incisions healed by first intention. There was no complications such as clavicle and coracoid fractures and Endobuton displacement. At last follow-up, the range of motion of the abduction improved from preoperative (77.5±4.5)° to (162.5±6.5)°, the range of motion of forward flexion improved from (84.1±5.2)° to (169.5±5.8)°, the Constant score improved from 42.5±2.3 to 92.4±2.3, the VAS score improved from 5.4±0.8 to 0.6±0.5, and the coracoid spacing reduced from (20.5±1.4) mm to (9.2±0.6) mm, all showing significant differences (P<0.05).ConclusionArthroscopic assisted double Endobutton “8” buckle fixation for the treatment of Rockwood Ⅲ type acute acromioclavicular joint dislocation is safe, less invasive, and quicker recovery. It can effectively alleviate shoulder pain, significantly improve the mobility of the shoulder joint, and achieve good short-term effectiveness.
ObjectiveTo explore the effectiveness of open reduction and internal fixation for bipolar fracture-dislocation of the forearm.MethodsBetween June 2014 and March 2019, 14 patients with bipolar fracture-dislocation of the forearm were treated. There were 9 males and 5 females, aged from 19 to 52 years (mean, 34.9 years). There were 8 cases of falling injuries, 4 cases of traffic accident injuries, 1 case of sports injury, and 1 case of machine strangulation injury. The time from injury to admission was 2-48 hours, with an average of 16.6 hours. All patients were closed injuries. All patients were treated with open reduction and internal fixation; the upper radioulnar joints were treated with circumferential ligament repair or lateral collateral ligament repair according to the joint stability. And the patients with lower radioulnar joint instability were also treated with the TightRope plate with loop fixation. After 3 weeks of plaster fixation, the patients started functional exercises. The fracture healing time, stability and range of motion of wrist and elbow joints, and forearm rotation function were recorded. The effectiveness was evaluated by Anderson’s forearm function score at last follow-up.ResultsThe incisions healed by first intention. All 14 cases were followed up 12-36 months with an average of 24.8 months. All fractures healed, with an average healing time of 14.9 weeks (range, 12-18 weeks). The stabilities of the upper and lower radioulnar joints restored well. At last follow-up, the elbow flexion and extension range of motion was 65°-160°, with an average of 124.6°; the wrist flexion and extension range of motion was 115°-165°, with an average of 155.0°; the forearm rotation range of motion was 65°-165°, with an average of 154.6°. According to Anderson’s forearm function score, 8 cases were excellent, 5 cases were good, and 1 case was unsatisfactory. ConclusionThe treatment of bipolar fracture-dislocation of the forearm needs comprehensive consideration and individualized treatment plan. The focus is to restore the anatomical structure of the radius and ulna and firm internal fixation, stabilize the upper and lower radioulnar joints, and perform functional exercises as soon as possible after operation to obtain satisfactory effectiveness.
Objective To observe the effectiveness of traumatic dislocation of the knee joint combined with multi ple ligament injuries treated by stages. Methods Between June 2005 and November 2008, 13 cases of traumatic dislocation of the knee joint combined with multi ple ligament injuries were treated by stages, including 9 males and 4 females with an average age of 30.7 years (range, 18-54 years). The dislocations were left knee in 3 cases and right knee in 10 cases. The causes of injury were sports injury in 8 cases, traffic accident injury in 2 cases, fall ing from height injury in 2 cases, and sprain injury in 1 case. The average time from injury to hospitalization was 9 hours (range, 6 hours to 2 days ). Anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and medial collateral ligament (MCL) were involved in 8 cases; ACL, PCL, and lateral collateral ligament (LCL) in 3 cases; and ACL, PCL, MCL, and LCL in 2 cases. The valgus stress testing results of 10 knees were ++ to +++; the varus stress testing results of 5 knees were ++ to +++; all knees showed positive in the anterior or the posterior drawer test and ++ to +++ in Lachman test. The nerve, vessel, MCL, LCL, PCL, meniscus were repaired in the first operation. The functional exercise of knee joint was done after fixation for 3-4 weeks. During the second operation, the ACL was reconstrcted under arthroscopy after the range of motion (ROM) of knee joint was good with anterior instabil ity of knee within 4-6 months. Results All wounds healed by first intention after two operations; no compl ications of infection and compartment syndrome occurred. All cases were followed up 12-60 months with an average of 36 months. Joint effusion of knee occurred in 2 cases at 4 weeks after the first operation and was cured after removal of fluid. At 3 months after the second operation, the results of valgus stress testing and Lachman test were ++ in 1 case, respectively; the results of valgus stress testing, varus stress testing, and Lachman test were + in 1 case, respectively; and others showed negative results. After 12 months of the second operation, the mean flexion of the knee was 123.4° (range, 100-135°), and the mean extension of the knee was 2.3° (range, 0-4°). According to Lysholm evaluation system, 9patients got excellent results, 2 good, and 2 fair; the excellent and good rate was 84.6%. Conclusion It is an effective method in the treatment of traumatic dislocation of the knee joint combined with multi ple ligament injuries by stages.
