Arthroscopic treatment of ankle impingement syndrome (AIS) is a minimally invasive surgical procedure used to address symptoms caused by impingement in the ankle joint. This syndrome occurs when there is abnormal contact between certain bones or soft tissues in the ankle, leading to pain, swelling, or limited range of motion. Traditionally, open surgery was the standard approach for treating AIS. However, with advancements in technology and surgical techniques, arthroscopic treatment has become a preferred method for many patients and surgeons. With improved visualization and precise treatment of the arthroscopy, patients can experience reduced pain and improved functionality, allowing them to return to their daily activities sooner. In this paper, we reviewed the application and clinical efficacy the of arthroscopic approach for treating AIS, hoping to provide a reference for its future promotion.

OBJECTIVE: To investigate the relationship between bone marrow edema and pathological changes, symptoms and signs of severe knee osteoarthritis. METHODS: From January 2020 to March 2021, 160 patients with severe knee osteoarthritis who underwrent MRI of the knee at the Department of Bone and Joint, Wangjing Hospital, China Academy of Chinese Medical Sciences were included. Eighty patients with bone marrow edema were selected as the case group, including 12 males and 68 females, aged from 51 to 80 years old with an average of (66.58±8.10) years old, the duration of disease 5 to 40 months with an average of (15.61±9.25) months. Eighty patients without bone marrow edema were selected as the control group, including 15 males and 65 females, aged from 50 to 80 years old with an average of (67.82±8.05) years old, the duration of disease 6 to 37 months with an average of (15.75±8.18) months, BMI was (28.26±3.13) kg·m^-2 ranged from 21.39 to 34.46 kg·m^-2. The degree of bone marrow edema was evaluated by knee whole oragan magnetic resonance imaging score (WORMS). The degree of knee osteoarthritis was evaluated by Kellgren- Lawrence(K-L) grade and Western Ontario and McMaster University Osteoarthritis Index (WOMAC). The degree of joint pain was evaluated by visual analogue scale(VAS) and WOMAC pain score, the joint signs were evaluated by tenderness, percussion pain, joint swelling and joint range of motion. To explore the relationship between bone marrow edema and knee osteoarthritis, the prevalence of bone marrow edema and K-L grade were compared between the two groups. Furthermore the WORMS score and WOMAC index, pain-related score, and sign-related score correlation coefficient were analyzed to further explore the relationship between bone marrow edema and knee osteoarthritis index, joint pain symptoms and signs. RESULTS: There was 68.75% (55/80) of the patients in the case group were in K-L grade Ⅳ, and 52.5% (42/80) in the control group, indicating a higher proportion of patients with grade Ⅳ in the case group than the control group (χ²=4.425, P<0.05). In the case group, there was a strong correlation between bone marrow edema WORMS score and knee osteoarthritis WOMAC index. (r=0.873>0.8, P<0.001), a moderate correlation between WORMS score and VAS score and WOMAC pain score(r=0.752, 0.650>0.5, P<0.001), a moderate correlation between WORMS score and percussion pain score (r=0.784>0.5, P<0.001), and a weak correlation between WORMS score and VAS and tenderness score, joint swelling score and joint range of motion score (r=0.194, 0.259, 0.296<0.3, P<0.001). CONCLUSION Our study suggests that severe knee osteoarthritis is associated with an increased risk of bone marrow edema. Bone marrow edema can also lead to knee osteoarthritis joint pain, with percussion pain being a positive sign, but tenderness, joint swelling and limitation of activity are not significantly related to bone marrow edema.

OBJECTIVE: To explore clinical symptoms and X-ray imaging features of cervical instability in young adult represented by postgraduates with a master's degree in medicine. METHODS: Totally 91 postgraduates with a master's degree in medicine were investigated from September to December 2021, including 45 males and 46 females;aged from 22 to 30 years old with an average of (25.30±2.18) years old. The cervical spondylosis-related discomfort symptoms of the subjects were collected and examined by the examiner for neck and shoulder tenderness point examination and cervical vertebra positive and lateral and functional X-ray radiography. According to the results of X-ray examination, the subjects were divided into stable cervical group and unstable cervical group. RESULTS: Among 91 subjects, there were 50 patients with cervical instability, accounting for 54.90% of total number of subjects. The cervical curvature was abnormal in 78 patients, accounting for 85.70% of total number of subjects. Among 50 patients with cervical instability, 50 patients were diagnosed as cervical instability on the basis of angular displaxement(AD)≥ 11 °, including 13 cases of C_3,4 instability, 30 cases of C_4,5 instability and 7 cases of C_5,6 instability;and 5 cases were diagnosed as cervical instability based on horizontal displacement(HD)≥ 3.5 mm, including 1 case of C_3,4 instability and 4 cases of C_4,5 instability. Compared with stable cervical group, the number of discomfort symptoms of neck pain, headache and shoulder pain in instability group was significantly higher than that of in stable cervical group(P<0.05);and the number of tenderness in spinous process space of C_4,5 and C_5,6, 2 cm adjacent to the spinous process of C₂-C₅ and the superior angle of the scapula (the stop point of levator scapulae) in the instability group was significantly higher than that in the stable cervical group (P<0.05);and the cervical curvature in the instability group was significantly lower than that in stable cervical group(P<0.05). CONCLUSION The incidence of cervical instability in young adult represented by postgraduates with a master's degree in medicine is high, they are mainly diagnosed as cervical instability on the basis of vertebral angular displacement ≥ 11°, and the instability segments are concentrated on C_3,4, C_4,5 and C_5,6 segments, the occurrence of cervical instability is often accompanied by abnormalities of cervical curvature. Most of clinical manifestations are head, neck and shoulder pain, especially neck pain in unstable segment.

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.

In this study, we reported a case of progressive pseudorheumatoid dysplasia in Peking University Third Hospital. A 56-year-old male patient presented with hip joint pain for more than 40 years and multiple joints pain with limitation of movements of these joints for 28 years. This patient suffered from joint pain and impaired range of motion of the hip, knee, elbow and shoulder gradually, associated with difficulty in walking and inability to take care of himself. He was diagnosed with "femoral head necrosis" or "ankylosing spondylitis" in local hospitals, but the treatment of nonsteroidal antiinflammatory drugs (NSAIDs) and sulfasalazine was not effective. Up to the age of 14, the patient displayed normal physical development, with the highest height was about 158 cm, according to the patient recall. However, his height was 153 cm at present. There was no history of similar illness in any family member. Physical examinations descried limitation of movement of almost all joints. Enlargement and flexion deformity of the proximal interphalangeal (PIP) joints of the hands resulted in the claw hand appearance. Limited abduction and internal and external rotation of the shoulder and hip could be find. He had normal laboratory findings for blood routine test, biochemical indexes and acute phase reactants such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Furthermore, HLA-B27 and autoimmune antibodies such as rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibody and antinuclear antibody (ANA) were all negative. X-ray of the hip showed loss of the joint space and irregularities of the femoral head, both femoral head were flattened, it could be see hyperplasia, osteophytes, bilateral femoral neck thicken, neck dry angle turned smaller. The radiological findings of the spinal vertebra indicated kyphosis deformity, narrowing of the intervertebral discs, vertebral syndesmophytes and flattening of the vertebra. However, there was no clues of bone marrow edema in the lumbar MRI. At last, genetic testing for the Wnt1-inducible signaling pathway protein 3 (WISP3) gene was done and indicated compound heterozygous mutations: 756C>G and c.866dupA. These two mutations were derived from the patient's mother and father (the patient's parents each had a heterozygous mutation). Two exons of the WISP3 gene had nucleotide changes leading to amino acid mutations. According to the patient's history, symptoms, physical examinations, radiological findings and genetic testing, the final definitive diagnosis was progressive pseudorheumatic dysplasia.

Snapping hip syndrome is a relatively common problem that can be easily managed with conservative treatment. This syndrome can be divided into external, internal and intra-articular types. Internal snapping hip syndrome is the rarest amongst these and its etiology is not well understood. We report a unique case of osteochondroma arising from the anterior inferior iliac spine (AIIS), which caused the internal snapping hip syndrome with hip pain and restriction of activity. This rare case of snapping hip syndrome from the AIIS was treated surgically and the symptoms completely disappeared after excision of the tumor.

Antegrade transmalleolar drilling method is one of the options for the treatment of osteochondral lesion of talus (OLT). We present five patients who underwent tibial drilling for treatment of OLT and later developed distal tibial cystic formation induced by cartilage opening or heat necrosis during drilling. Antegrade transmalleolar drilling can be a possible option for the treatment of OLT if the lesion is not easily reachable; however, other viable treatment should be considered due to its possibility of distal tibial pathologic change.

Anterior disc displacement is a common subtype seen in temporomandibular disorders (TMD) patients. It may cause mandibular movement disorders, such as clicking of joint, intermittent closed lock, limitation of mouth opening, etc. These disorders may affect the life qualities of patients. Anterior disc displacement may also cause mandibular malformations, especially among adolescents, which may affect the growth of condyle, therefore may have a correlation with mandibular retrusion or mandibular deviation when grown up. This paper going to review the influences of anterior disc displacement on oral mandibular function and morphology and their biological mechanisms.
