RESUMEN
Resumen: Introducción: El estadio final de la artropatía de manguito (AM) genera dolor e invalidez, el tratamiento mediante artroplastía invertida (AI) muestra buenos índices de reducción de dolor y mejoras en movilidad. El objetivo de nuestro trabajo fue evaluar de manera retrospectiva los resultados a mediano plazo de la artroplastía invertida de hombro en nuestro centro. Material y método: Retrospectivamente analizamos 21 pacientes (23 prótesis) sometidos a AI con el diagnóstico de AM. La edad media fue de 75.21 años. El seguimiento mínimo fue de 60 meses. Analizamos las escalas ASES, DASH y CONSTANT preoperatorias y en la última visita de seguimiento. Se analizó la escala VAS preoperatoria y postoperatoria y rango de movilidad preoperatoria y postoperatoria. Resultados: Mejoraron todas las escalas funcionales y dolor (p < 0.001). ASES en 38.91 puntos (IC 95% 30.97-46.84); CONSTANT en 40.89 puntos (IC 95% 34.57-47.21); DASH en 52.65 puntos (IC 95% 46.31-59.0) p < 0.001; y 5.41 puntos (IC 95% 4.31-6.50) en VAS. Mejoraron con significación estadística la flexión (66.52o a 113.91o); y la abducción (63.69o a 105.85o). No obtuvimos significación estadística en rotación externa ni en rotación interna. Aparecieron complicaciones en 14 pacientes; 11 notching glenoideo, una infección crónica, una infección tardía y una fractura intraoperatoria de glenoides. Conclusiones: La AI de hombro representa una alternativa eficaz para el tratamiento de la AM. Puede esperarse alivio del dolor y una mejoría en la flexión y abducción del hombro; la ganancia en rotaciones es poco predecible.
Abstract: Introduction: The final stage of rotator cuff tear arthropathy generates pain and disability, treatment with reverse shoulder arthroplasty shows in different published studies good rates of pain reduction and improvements in mobility. the objective of our study was to retrospectively evaluate the medium-term results of inverted shoulder replacement at our center. Material and methods: Retrospectively, we analyzed 21 patients (23 prosthetics) undergoing reverse shoulder arthroplasty with the diagnosis of rotator cuff tear arthropathy. The average age of patients was 75.21 years The minimum follow-up was 60 months. We analyzed in all preoperative ASES, DASH and CONSTANT patients, and a new functional assessment was made using these same scales at the last follow-up visit. We analyzed pre and postoperative VAS as well as pre and postoperative mobility range. Results: We achieved a statistically significant improvement in all functional scale and pain values (p < 0.001). The ASES scale showed an improvement of 38.91 points (95% CI 30.97-46.84); the 40.89-point CONSTANT scale (95% 34.57-47.21) and the 52.65-point DASH scale (95% 46.31-59.0) p < 0.001. We found an improvement of 5.41 points (95% CI 4.31-6.50) on the VAS scale. We also achieved a statistically significant improvement in flexion values 66.52o to 113.91o degrees; abduction 63.69o to 105.85o degrees at the end of the follow-up. We did not get statistical significance in terms of external rotation but with a tendency to improve in the obtained values; instead in internal rotation we obtained results that showed a tendency to worsen. Complications occurred during follow-up in 14 patients; 11 in relation to notching glenoid, one patient with a chronic infection, one patient with a late infection and one intraoperative fracture of glenoid. Conclusions: Reverse shoulder arthroplasty is an effective treatment of rotator cuff arthropathy. Pain relief and improvement in shoulder flexion and abduction can be expected especially; the gain in rotations is unpredictable.
RESUMEN
Objective To explore the effect of arthroscopic release combined with suture bridge treatment of old supraspinatus tendon tear with shoulder dysfunction.Methods 40 patients with old supraspinatus tendon tear were analyzed retrospectively.According to the operation method, the patients were divided into control group and experimental group with 20 cases each.Treatment of single row of loose strip anchor nails under arthroscope in control group, the experimental group was treated with the technique of loosening suture bridge under arthroscope.VAS score and ASES score were assessed before operation and after 1 month, 3 months, 6 months, and 12 months.Range of motion (ROM) was evaluated before operation and after 12 months.The analysis of complication was also preceded.Results All patients completed 12 months of follow-up.There were no difference between experimental group and control group in ASES score (27.6±5.5 vs 27.5±3.6), VAS score (7.6±0.5 vs 7.5±0.7) and shoulder bends forward[ (83.6±12.4) °vs (80.6±14.5) °], abduction[ (75.6±8.4) °vs (72.8±9.3) °], intorsion[ (20.1±3.7) °vs (21.2±2.9) °] at pre-operation (P＞0.05).At 1 month, 3 months, 6 months, and 12 months post-operation, VAS scores were 5.8±0.6, 4.2±0.5, 3.0±0.2 and 1.8±0.4 in experiment group and were 6.1±0.3, 4.4±0.6, 3.5±0.4 and 2.2±0.3 in control group, the difference was significant (P＜0.05).ASES scores were 35.8±3.6, 54.2±4.7, 73.1±3.2 and 85.8±2.6 in experiment group and were 34.1±3.3, 49.4±3.6, 69.5±2.4 and 72.2±3.1 in control group, the difference was significant (P＜0.05).After 12 months, there was a significant improvement in joint flexion, abduction, and lateral internal rotation in experimental group[ (160.4±10.2) °, (158.7±9.7) °, (48.1±5.9) °] than the control group[ (138. 4 ± 7. 2) °, (128. 7 ± 6. 5) °, (30.1 ± 4. 2) °]. No complications occurred in two groups, such as anchor loosening, pain, swelling and other complications. Conclusion Arthroscopic release combined with Suture Bridge can effectively improve the function of shoulder in patients with old supraspinatus tendon tear.
RESUMEN
Visual display terminal(VDT) is popular in majority of office in modern countries. Musculoskeletal pain due to repetitive work with VDT is a serious industrial accident at present. In recent studies, shoulder pain in VDT users is the most common problem in Korea. The purpose of this study was to evaluate and compare the effect of exercises on shoulder dysfunction in VDT-related female office workers. Of the l19 patients with shoulder dysfunction, 32 patients entered into the study. 16 patients(Group I) were not prescribed exercises, other 16 patients (Group II) performed throughout the specific shoulder exercises such as pendular exercises(forward, backward and circumduction) and sidelying external rotation exercises with weights. After 3 months of exercises, the two groups were compared in term of the pain rating scale, disability questionnaire score and range of motion score. The results were summarized as follows ; l. The pain rating scale in Group I before and after 3 months were not differenced significantly(p value=0.784) and in Group II, the scale before and after exercises were differenced significantly(p value=0.0005). 2. The disability, questionnaire scores in Group I before and after 3 months were not differenced significantly(p value=0.437) and in Group II, the scores before and after exercises were differenced significantly(p value=0.0002). 3. The ROM scores of the affected shoulder in Group I before and after 3 months were not differenced significantly(p value=0.876) and in Group II, the scores before and after exercises were differenced significantly(p value=0.0017). In conclusion, that the specific shoulder exercises on shoulder dysfunction in VDT-related female office workers are encouraged.
