Objective To explore the application value of carpal shoot through view in the palmar plating of distal radius fractures.Methods From March 2015 to May 2016,there were 62 acute distal radius fractures received various operation in our department,in which 48 patients were only performed volar locked plating.Among these 48 cases,there were 21 males and 27 females,with ages ranging from 17 to 75 years (mean 43.6±10.6 years).There were 15 cases of type A,11 cases of type B and 22 cases of type C distal radial fractures according to AO/OTA classification.All the operations were performed through modified Henry's approach between the radial artery and flexor carpi radialis.Once achieved satisfactory reduction,we performed rigid fixation of distal radius using anatomical locking plates.In all cases,bicortical drilling was performed.Screw lengths selected measured 1 to 2 mm less than the depth gauge number avoiding dorsal cortex penetration.After plate fixation of these 48 cases,standard posteroanterior and lateral radiographs were taken followed by the carpal shoot through view.To obtain carpal shoot through view,the patient's forearm was maximally supinated,the elbow flexed about 60°-70°and the wrist maximally dorsiflexed.The image intensifier beam is directed over the base of the thenar eminence.Compare the ratio of dorsal protrusion between standard view and carpal shoot through view,then statistical analysis was performed.After operation,CT scan was routinely taken to further test the effectiveness of carpal shoot through view.Results Five cases were detected dorsal cortex screw protrusion using standard posteroanterior and lateral views (10.4%,5/48).There were totally 16 cases (including the former 5 cases) of dorsal screw penetration uncovered by the carpal shoot through view(33.3%,16/48.Statistically significant difference was existed between the two fluoroscopy methods.Additionally,in 2 cases,a screw had penetrated the distal radioulnar joint (DRUJ),which was only apparent on the shoot through view.All the improper screws were exchanged and again were verified by the carpal shoot through view.The overall screw exchange rate was 37.5% (18/48).Conclusion Compared with standard AP and lateral fluoroscopy,the carpal shoot through view can reliably reveals dorsal screw penetration.Meanwhile,it provides excellent visualization of DRUJ.

Objective:
To evaluate a self-designed novel anatomical bone plate for fractures of ulnar coronoid process in cadaveric specimens.
Methods:
Our database search in the Imaging Center, Qilu Hospital of Shandong University (Qingdao) yielded CT reconstruction images of 45 normal adult elbows (26 males and 19 females) which met our criteria. On the 3D reformatted CT images, sagittal curvature angle of the ulnar coronal process (△1), tangent angle of the coronal process apex to olecranon fossa (△2), projective length (L) and projective height (H) were measured; the transverse width of the coronal process was also measured at 5 mm and 10 mm from the tip (K1 and K2). The minimum value was used for △2° in order to avoid cutting into the joint while the mean value for other parameters. After the shape of the plate and angles of the screws were designed using computer 3D software, a new anatomic plate for coronal process was produced. Five cadaver specimens were used to test the internal fixation of the coronal process with our novel anatomic bone plate. Attachment of the bone plate to the coronal process and screw penetration into the joint cavity were observed by X-ray and 3D CT scanning.
Results:
△1 was 45.52°±6.07°, △2 65.25°±7.09° (the minimum value 53.2°), L 52.27±7.78 mm, H 21.62±2.63 mm, K1 16.32±2.22 mm and K2 14.58±2.18 mm. Our new anatomic bone plate was designed based on the above data. X-ray and 3D CT scan after plate internal fixation showed that our self-designed bone plate produced fine attachment and no screws penetrated into the joint.
Conclusion
Our new anatomical bone plate may perfectly fit the anatomy of the adult ulnar coronal process in size and shape so that the coronary process can be fully covered and no screws will penetrate into the joint cavity.

Objective:
To explore a standard procedure for the treatment of combined dorsal and palmar internal fixation for complex four part distal radius fractures and assess its clinical results.
Methods:
From May 2009 to October 2016, 38 patients(39 sides)who suffered from complex four part distal radius fractures were performed operatively with open reduction and internal fixation via combined dorsal and palmar approach in Department of Orthopaedic Trauma, Qilu Hospital of Shandong University(Qingdao). The series included 22 males(22 sides) and 16 females(17 sides). Age of the patients was 53.5 years ranging from 25 to 79 years.According to Melone classification, there were 34 sides of type of Ⅳ, 5 of type Ⅴ.According to Frykman classification, there were 15 sides of type Ⅶ, 24 sides of type Ⅷ, and all the cases were type C3 according to AO/OTA classification.Preoperatively, the key articular fragments in four part distal radius fractures were identified and the individual fracture patterns from conventional X-ray and CT-scan were analyzed. All the patients were performed combined volar and dorsal fixation.Firstly, a palmar approach which gave access to and fix the palmar-ulnar fragment and the radial styloid fragment was performed.Then a limited dorsal approach across the third extensor compartment which gave access to the dorso-ulnar fragment and a limited dorsal arthrotomy to visualize the radiocarpal joint when necessary were performed.Through dorsal approach, we can address the dorso-ulnar fragment, free intra-articular fragment and direct visualize the joint.Use of a retinacular flap was routinely advocated to help prevent against tendon irritation and rupture.The follow-up control included conventional X-ray, range of motion(ROM), grip strength, and the disabilities of the arm, shoulder and hand index(DASH), as well as the patient-rated wrist evaluation(PRWE) score for functional outcome at 6 and 12 months.
Results:
Thirty-three patients(34 sides) were followed up for at least 12 months.The would healed well in all cases 2 weeks postoperatively, and no soft tissue infections, necrosis or neurovascular complications occurred.All the fractures of 38 cases(39 sides)healed averaged 3.6 months(ranging from 2.5-5.7 months), and no loss of reduction occurred postoperatively.Anatomic reconstruction with a step or gap of <1 mm was achieved in 37 cases(38 sides), Whereas 5 patients were lost to follow-up at 12 months postoperatively.ROM and grip strength were all recovered to over 85% of the unaffected side(exception of the bilateral patient). Median DASH-index and PRWE were 6.5(0-17) and 9.3(0-20)respectively.
Conclusion
Combined volar and dorsal approaches allow achieving anatomic reconstruction in complex four part intra-articular distal radius fractures and reveal good functional outcomes at intermediate follow-up.

Objective:To compare the efficacy of lateral elbow dislocation approach with non-dislocation approach for open reduction and internal fixation of distal humeral coronal fracture.Methods:A retrospective cohort study was used to analyze the clinical data of 26 patients with distal humeral coronal fracture admitted to Qilu Hospital (Qingdao) of Shandong University from January 2018 to October 2021, including 10 males and 16 females, aged 15-80 years [(51.6±4.9)years]. According to Dubberley classification, there were 10 patients with type 2A, 5 with type 2B, 6 with type 3A and 5 with type 3B. Overall, 12 patients were operated via lateral elbow dislocation approach (dislocation approach group) and 14 via lateral elbow non-dislocation approach (non-dislocation approach group). The operation time, intraoperative bleeding volume, incision healing, three-dimensional CT assessment of the reduction within one week after surgery (separation or step>2 mm as poor), Mayo elbow performance score (MEPS) at 3 months after surgery and fracture healing at the last follow-up were recorded in both groups. Complications were also compared between the two groups.Results:All patients were followed up for 3-18 months [(10.5±3.3)months]. The operation time was (146.9±15.5)minutes in dislocation approach and (122.7±11.1)minutes in non-dislocation approach group ( P>0.05). The intraoperative bleeding volume was (113.3±9.7)ml in dislocation approach and (112.9±10.1)ml in non-dislocation approach group ( P>0.05). All incisions healed uneventfully in stage I. All patients had good reduction in dislocation group, while only 7 patients had good reduction and the other 7 patients presented a separation or step>2 mm in non-dislocation group ( P<0.05). The MEPS was (90.0±1.4)points in dislocation approach group at 3 months after surgery, including 9 patients being rated as excellent and 3 good, with the excellent and good rate of 100%. In constrast, the MEPS was (78.9±2.9)points in non-dislocation approach group at 3 months after surgery, including 5 patients being rated as excellent, 4 good, 4 fair and 1 poor, with the excellent and good rate of 64.3% ( P<0.05). All fractures were healed at the last follow-up. In non-dislocation approach group, osteoarthritis occurred in 7 patients, including 3 with screw protrusion, 2 with heterotopic ossification and 2 of advanced age with osteophyte formation around the joint. In dislocation approach group, osteoarthritis occurred only in 2 patients of advanced age, showing osteophyte formation around the elbow joint, with no screw cutting or heterotopic ossification. Conclusion:For distal humeral coronal fracture, the lateral elbow dislocation approach is able to provide complete exposure of the articular surface, obtain anatomic reduction, restore elbow function and reduce complications when compared with the non-dislocation approach.

Objective:To compare reconstruction of acromioclavicular ligament versus internal fixation of acromioclavicular joint with clavicle hook plate in the treatment of Rockwood Ⅲ-Ⅴ acromioclavicular dislocation by reconstruction of coracoclavicular ligament with suture anchor.Methods:A retrospective analysis was conducted of the 56 patients who had been treated for Rockwood Ⅲ-Ⅴ acromioclavicular dislocation from January 2015 to June 2019 at Department of Orthopaedic Trauma, Qilu Hospital of Shandong University (Qingdao). Of them, 26 were treated by reconstruction of coracoclavicular ligament with suture anchor plus reconstruction of acromioclavicular ligament (reconstruction group) and 30 by reconstruction of coracoclavicular ligament with suture anchor plus internal fixation of acromioclavicular joint with clavicle hook plate (plate group). The 2 groups were compared in terms of operation time, intraoperative blood loss, Constant-Murley score and Subjective Shoulder Rating System (SSRS) score at the last follow-up, and complications.Results:The 2 groups were comparable because there were no significant differences between them in the baseline data before operation ( P>0.05). The reconstruction group was followed up for 6 to 15 months (average, 7.9 months) while the plate group for 7 to 18 months (average, 11.3 months). The average operation time was (79.9±12.6) min for the reconstruction group and (69.1±8.5) min for the plate group, showing a significant difference ( P<0.05). No significant difference was found between the 2 groups in the intraoperative blood loss [(68.5±19.1) mL versus (65.0±16.6) mL] ( P>0.05). The differences were statistically significant between the 2 groups in Constant-Murley score (87.9±3.4 for the reconstruction group versus 91.9±3.5 for the plate group) and in SSRS score (85.1±4.1 for the reconstruction group versus 88.6±3.0 for the plate group) ( P<0.05). All the wounds healed well in the reconstruction group except for one patient who reported numbness around the wound which disappeared spontaneously 3 months postoperation. In the plate group, incision infection occurred in 2 cases, the redness and swelling in one which responded to dressing change 3 weeks later and numbness around the incision in one which was recovered 5 months after operation. Conclusions:Both surgical procedures can achieve good to excellent clinical outcomes. Although reconstruction of both acromioclavicular and coracoclavicular ligaments takes more operation time, it may lead to better Constant-Murley and SSRS scores and fewer complications, and spare secondary operation.

Objective:To investigate the therapeutic effect of bidirectional-traction, Steinmann pin poking reduction,anatomic plate and raft technique in the treatment of hyperextension tibial plateau fractures.Methods:The data of 25 patients with hyperextension tibial plateau fractures admitted to Qilu Hospital of Shandong University (Qingdao) from July 2017 to June 2022 were retrospectively analyzed. According to the treatment methods, they were divided into bidirectional-traction group (treated with bidirectional-traction, Steinmann pin poking reduction, anatomic plate and raft technique) and open reduction group (treated with open reduction, bone grafting and two plates fixation). The bidirectional-traction group included 14 patients, with 8 males and 6 females; the age was 50.29±9.23 years (range, 38-61 years). The cause of the injury was a traffic accident in 4 patients, a fall from height in 7 patients and a fall from standing height in 3 patients. According to Schatzker classification, there were 5 Schatzker type V and 9 type VI fractures. The open reduction group included 11 patients (7 males and 4 females); with a mean age of 58.00±10.58 years (range, 48-69 years). 3 cases were injured by traffic accident, 6 cases by falling from height, and 2 cases by falling from standing height. According to Schatzker classification, there were 4 type V and 7 type VI. Preoperative waiting time, operative time, blood loss and percentage of blood loss, incision length, fracture healing time, tibial posterior inclination, medial proximal tibial angle, visual analogue scale (VAS) on the first day after surgery, Hospital for Special Surgery (HSS) score 6 months after surgery were compared between the two groups.Results:Patients in both groups were followed up for more than 6 months. The follow-up time was 7 to 48 months with an average of 22.76 months. There were significant differences in the preoperative waiting time [6 (4, 8) d vs. 8 (7, 11) d, W=114.00, P=0.043], the incision length [15.0 (12.5, 16.0) cm vs. 30.0 (28.0, 31.0) cm, W=154.00, P<0.001], postoperative VAS [4 (3, 4) points vs. 5 (5, 6) points, W=143.00, P<0.001], blood loss [147 (107, 206) ml vs. 267 (191, 362) ml, W=116.00, P=0.033], blood loss percentage [2.95% (2.58%, 5.20%) vs. 6.40% (4.05%, 7.00%), W=118.00, P=0.027] between the bidirectional-traction group and open reduction group. There were not significant differences in the operation time [120 (118, 120) min vs. 119 (101, 154) min, W=68.50, P=0.656], fracture healing time (8.18±1.03 weeks vs. 8.86±1.27 weeks, t=1.49, P=0.149), HSS score (8.43±3.72 vs. 85.18±7.73, t=1.28, P=0.221) and medial proximal tibial angle 6 months after surgery (87.66°±1.53° vs. 86.47°±2.24°, t=1.57, P=0.130) between the two groups. Postoperative tibial posterior inclination was improved in both groups. There was no significant difference in the tibial posterior inclination before surgery, immediately after surgery and 6 months after surgery (-14.96°±6.44°, 5.55°±1.02°, 5.61°±0.82°) in the bidirectional-traction group and -12.26°±2.93°, 7.07°±3.21° and 7.14°±3.17° in the open reduction group, P>0.05). There were no postoperative complications such as acute compartment syndrome or knee stiffness in both groups. Conclusion:The treatment of hyperextension tibial plateau fracture with bidirectional-traction, Steinmann pin poking reduction, anatomic plate and raft technique can shorten preoperative waiting time, reduce incision length, decrease blood loss and lower VAS. It is a minimally invasive, rapid and effective method, which has achieved good clinical results and is worth promoting.
