Objective To investigate the method and effectiveness of coracoplasty with mini-incision for subcoracoid impingement syndrome. Methods Between May 2006 and September 2011, 4 patients with subcoracoid impingement syndrome were treated, including 3 cases of congenital dysplasia of the coracoid process and 1 case of anterior glenohumeral instability. There were 3 males and 1 female with an average age of 36 years (range, 20-56 years). The disease duration was 6-22 months (mean, 11.2 months). The patients had a history of chronic pain and click of the anterior should, which was aggravated in adduction, internal rotation, and flexion. The results of the coracoid impingement test were positive by Neer and Hawkins-Kennedy impingement sign. The axial CT in adduction position showed that the coracohumeral interval decreased and coracoid index increased. The 2 cm lateral coracoid incision was made and the 0.5-1.5 cm coracoid neck was revealed and cut by osteotomy. The coracoplasty was performed by amputating the conjoined tendon insertion of the short head of the biceps and the coracobrachialis muscle and suturing to proximal coracoid osteotomy surface. Shoulder was fixed with the external braces for 6 weeks. Results Healing of incision by first intention was observed in all cases without any complication. All the 4 patients were followed up from 8 months to 5 years. At last follow-up, pain and click disappeared. The mean visual analogue scale (VAS), University of California at Los Angeles (UCLA), Constant, and simple shoulder test (SST) scores were significantly improved from 7.75, 10.25, 65.50, and 9.75 at preoperation to 0.25, 34.25, 91.25, and 0.25 at last follow-up respectively. The axial CT in adduction position and MRI showed that long coracoid process was removed; the coracohumeral interval was increased to 13.38 mm from 4.16 mm at preoperation; and the coracoid index was decreased to 0.28 mm from 13.08 mm at preoperation. Conclusion Coracoplasty with mini-incision is an effective method to relieve clinical symptoms of subcoracoid impingement, which has less complications and faster recovery.
Objective To introduce a new approach of neurotization to treatment of the shoulder syndrome after the radical neck dissection by using transpositional anastomosis of C7 posterior root and the spinal accessory nerve to reconstruct the function of trapezius muscle. Methods From March 1999 to February 2001, 10 patients underwent the neurotization during the radical neck dissection. In the operation, the apo-cranial part of spinal accessory nerve was preserved from the trapezius muscle (gt;3.0 cm in length) and anastomosed to C7 posterior root. Objective physical examinations and electromyography were conducted before and after operation.One, 6 and 12 months after operation the trapezius muscle function after the transpositional anastomosis was evaluated. Results One, 6 and 12 months after operation, the recovery rates of each part were as follows: 9.8%, 68.9% and 73.5% in upper part; 4.7%, 73.6% and 69.4% in middle part; and 6.2%, 70.5% and 70.3% in lower part. The range of abduction motion of upper arm in 7 cases (70%) exceeded 90°. The mean maximal abduction angle was more than 95°. Evaluation of the shoulder function showed that myoatrophy was mild and the disability of abduction was classified as grade Ⅱ in 7 cases and grade Ⅲ in 3 cases. Conclusion Transpositional anastomosis of the C7 posterior root to thespinal accessory nerve after radical neck dissection can well reconstruct the function of trapezius muscle. This approach provides a wide indication in comparison with the functional neck dissection without impairment of arm function afterthe cutting of C7.
Objective To explore the feasibility and short-term effectiveness of the modified radical resection and reconstruction in the treatment of malignant proximal humerus tumor. Methods The relevant anatomic data from 30 normal adult shoulder joint MRI were measured to analyze the feasibility of modified radical resection and reconstruction surgery in the treatment of malignant proximal humerus tumor. Five patients with malignant proximal humerus tumor were treated by using the modified radical resection and reconstruction surgery between March 2012 and January 2016. There were 1 male and 4 females, aged from 9 to 69 years (median, 46 years). There were 4 cases of osteosarcoma (Enneking IIA in 2 cases and Enneking IIB in 2 cases) and 1 case of metastatic carcinoma (moderately differentiated adenocarcinoma). The disease duration was 7 to 12 months (mean, 9 months). Recurrence of tumor was observed after operation, and the shoulder function was assessed according to Enneking skeletal muscle tumor function scoring system. Results Radiographic results showed that modified radical resection and reconstruction surgery was feasible, which was in allowable range of the maximum longitudinal diameter ( < 29.8 mm) and depth ( < 4 mm). The operation was successfully completed in all 5 cases, and pathological examination suggested that purposes of radical resection had achieved. All patients were followed up 3 to 49 months (mean, 15.6 months). One patient had local recurrence at 12 months after operation, and a shoulder joint amputation was performed; the other 4 patients had good prosthesis survival. At last follow-up, the function of the shoulder joint was obviously recovered when compared with preoperative function; Enneking's skeletal muscle tumor function score was 25.8 points (range, 24 to 27 points). Conclusion Modified radical resection and reconstruction surgery is feasible for the treatment of proximal humerus tumor, and it can maintain a good early shoulder function.
ObjectiveTo systematically review the efficacy and safety of extracorporeal shock wave therapy (ESWT) in the treatment of rotator cuff tendinopathy to provide evidence for clinical practice. MethodsDatabases including CENTRAL, MEDLINE, EMbase, CINAHL plus, PEDro, CNKI, CBM, WanFang Data, and VIP were searched to collect randomized controlled trials (RCTs) of ESWT in the treatment of rotator cuff tendinopathy from inception to January 11th, 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software. ResultsA total of 12 RCTs from 11 articles were included, including 529 subjects (273 in the case group and 256 in the control group). Meta-analysis showed that no significant difference between ESWT and placebo in pain improvement (SMD=−1.08, 95% CI −2.45 to 0.29, P=0.12), superior pain improvement in ESWT group than electroacupuncture group (SMD=−7.15, 95%CI −8.50 to −5.80, P<0.000 01), and no significant difference in pain improvement between ESWT as adjuvant therapy and acupuncture alone (SMD=−4.32, 95%CI −11.93 to 3.29, P=0.27). Regarding the Constant–Murley score (CMS) for shoulder joint function, ESWT was associated with an improved CMS compared with placebo (SMD=1.31, 95%CI 0.08 to 2.53, P=0.04). There was no significant difference in the improvement in the CMS between ESWT and other treatments (SMD=0.13, 95%CI −2.07 to 2.53, P=0.91). There was no significant difference in the improvement in the CMS between ESWT as adjuvant therapy and acupuncture alone (SMD=1.68, 95%CI −0.69 to 4.05, P=0.16). ConclusionsESWT may improve shoulder joint function in patients with rotator cuff tendinopathy, and the alleviation of pain in patients with rotator cuff tendinopathy requires further investigation. Due to the limited quality and quantity of included studies, the above conclusions requires further investigation by more high-quality studies.
