Objective: MRI images were used to study the efficacy of anterior repositioning splint (ARS) in the treatment of different types of disc displacement with reduction (DDWR) in temporomandibular joint. Methods: From September 2020 to December 2021, 26 patients with DDWR were enrolled in the Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Zhengzhou University. There were 5 males and 21 females with an average age of (20.8±5.8) years. ARS was used for 3-6 months. The changes of joint clicking, opening type and joint pain before and after treatment were compared. The changes of disc position, disc-condyle angle and condylar bone mass before and after treatment were compared by MRI. Paired t-test was performed on the disc-condyle angle before and after treatment, Fisher's exact test was performed on the change of disk position, and other count data were expressed as rate (%). Results: After ARS treatment, the effective rates of joint clicking,abnormal opening, joint pain and disc displacement were 97%(35/36), 14/18, 7/9 and 95%(36/38). MRI analysis found that there was a significant difference between the disc position before and after treatment (P<0.001), MRI analysis showed that the anterior disc displacement (48%, 25/52) and the anterolateral disc displacement (17%, 9/52) were the most common before treatment. In contrast, the normal superior disc (75%, 39/52) and the anterior disc displacement (17%, 9/52) were the most common after treatment, no significant changes were seen after treatment in the anteromedial disc displacement. The disc-condylar angle was (36.09±19.02) ° before ARS treatment and (3.94±10.12) ° after ARS treatment(t=9.23, P<0.001). After treatment, 46% (12/16) of the patients showed new bone formation, and the height of the condyle recovered. Conclusions: The clinical efficacy of ARS in the treatment of anterior disc displacement and anterolateral displacement of temporomandibular joint is remarkable, which can restore the disc-condylar relationship of most patients with indications.

Objective: To investigate the reduction effect of hoding cricoarytenoid joint reduction with visual laryngoscope under intravenous anesthesia. Methods: The therapeutic effects of 40 patients with arytenoid dislocation(AD)treated by closed reduction in the single center from January 2020 to September 2021 were retrospectively analyzed, including 21 males and 19 females, median age 48 years. The etiology, symptoms, preoperative evaluation methods, reduction mode, reduction times, and the recovery of arytenoid cartilage movement and sound after reduction were evaluated and analyzed. Results: All patients had obvious hoarseness and breath sound before treatment. Under stroboscopic laryngoscope or electronic nasopharyngoscope, different degrees of vocal cord movement disorder and poor glottic closure can be seen. There were 28 cases of left dislocation, 9 cases of right dislocation and 3 cases of bilateral dislocation. The etiology of dislocation of cricoarytenoid joint: 25 cases (62.5%) of tracheal intubation under general anesthesia were the most common causes, was as follows by laryngeal trauma, gastroscopy, cough, vomiting and so on. Among them, 28 cases of reduction were initially diagnosed in our department, and 12 cases were diagnosed later after failure of reduction treatment. Of the 40 patients, 6 underwent reduction 24 hours after dislocation; 18 cases from 3 days to 1 month; 7 cases from 1 to 3 months; 6 cases were reset in 3~6 months; Over 6 months in 3 cases. After one reduction, 10 cases (10/40, 25%) recovered normal pronunciation, 14 cases (14/40, 35%) recovered normal pronunciation after two reduction, 10 cases (10/40, 25%) recovered normal pronunciation after three times, 2 cases (2/40, 5%) recovered normal pronunciation after four times, and 1 case (2.5%) recovered normal pronunciation after five times. Thin slice CT scan of larynx and cricoarytenoid joint reconstruction showed the types of AD: subluxation in 37 cases (92.5%) and total dislocation in 3 cases; 28 cases of left dislocation, 9 cases of right dislocation and 3 cases of bilateral dislocation; 29 cases (72.5%) had posterior dislocation and 11 cases (27.5%) had anterior dislocation. All patients were treated by intravenous anesthesia with arytenoid cartilage clamped by cricoarytenoid joint reduction forceps under visual laryngoscope. The curative effect was evaluated by stroboscopic laryngoscope and/or voice analysis at 1-2 weeks after operation. The vocal cord movement returned to normal and the pronunciation was good in 37 cases (92.5%). Conclusions: Hoding cricoarytenoid joint reduction with the vision laryngoscope under intravenous anesthesia is easy to operate and the reduction effect is more stable. It is a effective method for AD.

OBJECTIVE: To explore and compare the safety depths of perpendicular and oblique acupuncture at Yamen (GV 15) in patients with atlantoaxial dislocation (AAD) and healthy volunteers. METHODS: One bundred and seventy-seven patients with atlantoaxial dislocation were selected as an AAD group, and 207 patients without atlantoaxial dislocation and with normal anatomical structure were selected as a normal group. All participants were moderately sized. The MRI scanning of the cervical vertebra was performed, and the safety depth of perpendicular and oblique acupuncture at Yamen (GV 15) was calculated on the sagittal image. RESULTS: In the AAD group, the safety depth of men was (45.33±5.17) mm for perpendicular acupuncture and (48.58±4.41) mm for oblique acupuncture; the safety depth of women was (44.17±7.80) mm for perpendicular acupuncture and (47.49±7.32) mm for oblique acupuncture. In the normal group, the safety depth of men was (47.72±5.06) mm for perpendicular acupuncture and (42.69±5.53) mm for oblique acupuncture; the safety depth of women was (44.63±5.85) mm for perpendicular acupuncture and (39.88±6.18) mm for oblique acupuncture. The safety depth of men and women for oblique acupuncture was longer than that for perpendicular acupuncture in the AAD group (<0.01); the safety depth of men and women for oblique acupuncture was shorter than that for perpendicular acupuncture in the normal group (<0.01). The safety depth of perpendicular and oblique acupuncture between men and women was not significant in the AAD group (>0.05); the safety depth of perpendicular and oblique acupuncture for men was longer than that for women in the normal group (<0.01). For men, the safety depth of perpendicular acupuncture in the AAD group was shorter than that in the normal group (<0.01), while the safety depth of oblique acupuncture in the AAD group was longer than that in the normal group (<0.01). For women, the safety depth of perpendicular acupuncture in the AAD group was similar with that in the normal group (>0.05), while the safety depth of oblique acupuncture in the AAD group was longer than that in the normal group (<0.01). CONCLUSION The safe depth of acupuncture at Yamen (GV 15) has significantly changed under AAD, so during the clinical acupuncture the needle insertion should be less than its safe depth.

Acromioclavicular joint (ACJ) injury is a common shoulder injury. There are various techniques of ACJ reconstruction. Superficial infection after ACJ reconstruction is not an uncommon complication. However, osteomyelitis post ACJ reconstruction has never been highlighted as a possible complication. Our patient is a 31-year-old male who sustained a Rockwood 5 ACJ dislocation and had anatomical ACJ reconstruction with autogenous gracilis and semitendinosus graft. Our technique involved the anatomical reconstruction of the ACJ and the coracoclavicular ligament with the usage of two bioscrews and the temporary stabilisation of the ACJ with two k-wires. As in any orthopaedic surgery, infection is often disastrous especially when the surgery involves implants. It can be disastrous with high morbidity to the patient as well as a costly complication to treat. Therefore, we wish to highlight this case as despite its rarity, osteomyelitis can be devastating to the patient and should be prevented if possible.

OBJECTIVE: To analyze the clinical effect of Zhuang medicine tendon therapy combined with chiropractic manipulation in treating sacroiliac joint dislocation. METHODS: From January 2017 to May 2018, 60 patients with sacroiliac joint dislocation were divided into treatment group and control group according to the order of admission. There were 19 males and 11 females in the treatment group, aged from 23 to 52 (38.97±3.23) years old, with a course of 2 h to 5.1 months, with an average of (2.19±1.12) months. There were 14 males and 16 females in the control group, aged from 26 to 50 (39.07±3.30) years old, with a course of 3 h to 6 months, with an average of(2.41±1.05) months. The treatment group was treated with Zhuang medicine tendon therapy combined with chiropractic manipulation, while the control group was treated with conventional acupuncture and massage. Before treatment, the main clinical symptoms of the patients were lumbosacral pain, posterior superior iliac spine not at the same level and accompanied with dyskinesia. The pelvic separation test and the "4" test were positive. After treatment, the curative effect was evaluated according to the improved Macnab standard and the "score of treatment of lumbar diseases". RESULTS: Sixty patients were followed up for an average of 8 months. At the latest follow-up, the clinical effect of modified Macnab was better in the treatment group than in the control group(<0.01). After treatment, the treatment group was better than the control group on lumbar function score (<0.01). CONCLUSIONS The treatment of sacroiliac joint dislocation by Zhuang medicine tendon therapy combined with chiropractic manipulation has good clinical effect and is worth further application and development.

Dislocation of the radial head in adults is uncommon. A simultaneous dislocation of the radial head and fracture of the ipsilateral distal end of radius with no other associated injuries is extremely rare. As far as we know, such an injury after an unusual mode of injury has been seldom reported in the English literature. We report such a case without any associated injuries or comorbidity. Closed reduction was performed within two hours after injury and results were satisfactory. Immobilisation was continued for 3 weeks. Gradual mobilisation was started after removal of the plaster under the supervision of a physiotherapist. At 6 months'follow-up, the patient had no residual pain at the elbow with full flexion and extension. Almost full supination with a restriction of last 10 degrees of pronation was achieved. There was no evidence of instability of the elbow.

OBJECTIVETo analyze appropriate strategy about treatment of rotatory dislocation of atlantoaxial articulation in children.

METHODSFrom March 2005 to February 2009, 36 patients with rotatory dislocation of atlantoaxial articulation were retrospectively analyzed, including 25 males and 11 females, with the average age of 7.8 years (ranged 3 - 14 years). According to Fielding-Hawkins clinical classification, type I 24 cases, type II 8 cases, type III 2 cases, type IV 2 cases. All of the patients were assessed rotatory dislocation of atlantoaxial articulation and whether or not upper cervical spine malformation by X-ray, MRI and CT scan and three-dimensional reconstruction. Thirty-two cases received observational treatments which were reduction after cervical traction, without appearance of the deformity, without neurological symptoms. And another 4 serious cases (irreducible atlantoaxial dislocation or with os odontoideum) received posterior atlantoaxial fixed autograft fusion.

RESULTSRotation of atlas decreased from 16.0° ± 4.4° (range, 5° to 26°) pre-therapy to 4.5° ± 1.5° (range, 0° to 8°) post-therapy in 35 cases, rotation of atlas had significant difference between pre-therapy and post-therapy (t = 14.75, P < 0.05). One patient pre-therapy rotation of atlas was 45°, post-therapy was 4°. All patients were followed up for 14 - 38 months (mean, 18 months), 32 cases who received cervical traction and external fixation resulted in satisfactory outcome in which all the ankylodeire were disappear, bilateral masses were symmetrical on anterior-posterior and good functional activities of cervical. All the 4 cases surgically treated obtained reduction, sound bony fusion and neural symptoms were improved obviously after operation.

CONCLUSIONSConservative treatment has been proved to be very effective in most of rotatory dislocation of atlantoaxial articulation in children. However, operative treatment should be considered in the following situations: irreducible atlantoaxial dislocation or patients with os odontoideum.

OBJECTIVETo observe the effects of shoulder lift reduction for treatment of posterior dislocation of hip joint.

METHODSFrom July 2001 to June 2010, 14 cases of posterior dislocation of hip joint were treated with shoulder lift reduction involving 12 males and 2 females with an average age of 34.6 years ranging from 18 to 57 years. After recduction, all patients were assisted with the traction, exercise and traditional Chinese medicine. The mean duration between injured and treatment was 1.1 days (2 hours to 3 days). According to Harris scoring system the hip joint function were evaluated.

RESULTSAll patients were followed-up for 8 to 24 months (means 16 months). Fourteen cases were reset well in first without any complication. The Harris score was (97.14 +/- 4.90) in total, involving hip pain (42.86 +/- 1.88), articular activity (4.71 +/- 0.47), daily activity (45.57 +/- 9.26), deformity (4.00 +/- 0.00), the clinical outcome was excellent in 12 cases,good in 2. There were not complications such as avascular necrosis of the femoral head, and so on.

CONCLUSIONThe shoulder lift reduction can be used by one person, and the treatment of posterior dislocation of hip joint is effective. It established a good foundation for the rehabilitation of trouble hip.
