ABSTRACT

Objective:To study the clinical efficacy of modified open elbow arthrolysis in the treatment of traumatic elbow stiffness.Methods:A retrospective analysis was performed on 120 patients who underwent modified open elbow arthrolysis in Beijing Jishuitan Hospital from January 2018 to December 2020. The age of the included patients was (37.7±12.4) years (ranged 18-64 years), including 54 males and 66 females. The medical records were reviewed, the range of motion (ROM) and functional status of the patients before operation and at the last follow-up were compared including visual analogue scale (VAS), Mayo elbow performance score (MEPS), Disabilities of the arm, shoulder and hand (DASH) score. Complications and secondary operations were also recorded. Measurement data with normal distribution were presented as mean ± standard deviation( ± s) and comparison between groups was conducted using the t-test; Measurement data of skewed distribution were expressed as M ( Q1, Q3), and Rank-sum test was used for inter-group comparison. Results:The preoperative extension of 120 patients was 43.6° (33.8°, 60.1°), the flexion was 78.7° (59.8°, 98.1°), and the flexion-extension ROM was 25.6° (0.0°, 54.5°); the preoperative pronation was 51.8° (33.0°, 67.0°), the supination was 85.1° (65.7°, 90.0°), and the rotation ROM was 136.9° (99.1°, 157.5°). Postoperative extension was 14.2° (7.0°, 24.8°), flexion was 129.5° (120.0°, 138.1°), flexion-extension ROM was 115.5° (94.4°, 127.3°); postoperative pronation was 65.0° (47.1°, 75.0°), the supination was 88.3° (78.6°, 90.0°), and the rotation ROM was 151.9° (131.7°, 163.4°). Postoperative extension, flexion, flexion-extension ROM, pronation, supination, and rotation ROM were all higher than those before operation, and the differences were statistically significant ( P<0.001). The VAS of 120 patients was 1.0 (0.0, 3.0) scores before operation and 0.0 (0.0, 1.0) scores after operation. The MEPS was 60.0 (50.0, 75.0) scores before operation and 100.0 (85.0, 100.0) scores after operation. The preoperative DASH was 37.5 (20.1, 51.3) scores, and the postoperative DASH was 7.9 (3.3, 13.3) scores. The postoperative VAS, MEPS, and DASH were significantly improved compared with those before operation, and the differences were statistically significant ( P<0.001). Residual ulnar nerve symptoms occurred in 18 cases, recurrence of heterotopic ossification in 42 cases, and hematoma in 3 cases. Conclusions:Modified open elbow arthrolysis is a safe and effective surgical method for the treatment of traumatic elbow stiffness. It can significantly improve the function of the patient, reduce the occurrence of elbow instability, avoid the use of external fixators, and reduce the cost of the patient.

ABSTRACT

Objective To evaluate clinical and radiographic outcomes associated with total hip arthroplasty (THA) using metal-on-metal prosthesis with large diameter femoral head.Methods From October 2007 to December 2007,41 patients (49 hips) underwent large diameter femoral head metal-on-metal THA in our hospital were involved in this study.Clinical outcomes measures were Harris score,hip range of motion and incidence of complications.Abduction angle and anteversion angle of cup were measured on radiological films.The radiolucent line and osteolysis around the prosthesis were also recorded.Results Thirty-nine patients (47 hips) were followed up at least 2 years.The average Harris hip score had improved from (43.8±13.1) points preoperatively to (92.0±5.4) points at final follow-up.All the patients had attained satisfactory results.No late complication happened.For the rang of motion at final follow-up:flexion of the hip had improved from 79.8° to 113.2°,abduction had improved from 20.9° to 40.2°,external rotation had improved from 12.0° to 30.8°.Radiological measurement showed the mean abduction angle of cup was 39.5°±4.9°,the mean anteversion angle of cup was 14.5°±2.1°.No radiolucent line and osteolysis were found after THA.Conclusion The short-term effects of THA using metal-on-metal prosthesis with large diameter femoral head is encouraging,especially for young patients.
