RESUMEN
The purpose of this study is to evaluate radiological, clinical results and complication rates of dual plate fixation for severe metaphyseal comminuted fracture of proximal humerus. 21 patients who have proximal humerus fractures with impaired posteromedial buttress were enrolled. Fractures were treated with dual plate technique using Proximal Humeral Locking plate and Variable Angle Plate. Radiographic results were analyzed based on duration of union. For evaluation of the degree of anatomical reduction, neck shaft angle on the anteroposterior view was measured by simple plain radiography using the Paavolainen method, while anterior-posterior angulation was measured on the axial view. Degree of anatomic reduction was good in 17 patients (80.95%), fair in 3 patients (14.28%), and poor in 1 patient (4.77%). One case of impingement, and one case of avascular necrosis were noted. The dual plate technique provides stable fixation and satisfactory clinical and radiological results for severely comminuted metaphyseal fracture of the proximal humerus.

INTRODUCTION: Adequate treatment for periprosthetic distal femur fractures is challenging because of various reasons, including severe osteoporosis and distal fragments that are too small or too distal. We have introduced a new surgical technique for dual plating of periprosthetic distal femur fractures following total knee arthroplasty (TKA) and determined the clinical and radiological outcomes of minimally invasive plate osteosynthesis (MIPO) with a dual locking compression plate (LCP). MATERIALS AND METHODS: Between January 2010 and July 2019, 18 patients [mean age, 74.8 (68-89) years; average follow-up period, 14.8 (12-43) months] underwent MIPO with distal femoral LCP laterally and proximal humeral internal locking system (PHILOS) medially for periprosthetic distal femoral fractures following TKA. The minimum follow-up was 1 year. The clinical and radiological outcomes were assessed using the modified WOMAC scores, knee range of motion, time to callus formation, time to union, and complications of malunion, nonunion, and shortening. RESULTS: The average time to union was 18.4 weeks (range, 10-51 weeks) and to callus formation was 7.8 weeks (range, 2-14 weeks). At the 1-year follow-up, the average JLETS was 37.6 (range, 24-53), average knee ROM was 110.3° (range, 80-135°), and average varus-valgus angles of the distal femur were 3.2° (range, -2.9-10.5°). No nonunion, broken plates, or implant failure occurred. Malunion occurred in three patients. CONCLUSION: MIPO with dual LCP is a reliable method for stabilizing periprosthetic distal femoral fractures following TKA, with satisfactory bone union rates and low complication rates.

INTRODUCTION: Intramedullary nailing (IMN) is currently considered the gold standard in the surgical treatment of tibial shaft fractures in adult patients. In this case-control comparative study, we aimed to compare the efficacy of minimally invasive plate osteosynthesis (MIPO) and IMN in treating tibial shaft fractures. MATERIALS AND METHODS: The clinical and radiological outcomes, such as a modified trauma scale, operation time, fracture healing, rate of re-operation, and complications such as malunion, nonunion, shortening, and infection were assessed between IMN and MIPO for the treatment of tibial shaft fractures. RESULTS: Seventy-three skeletally mature patients who underwent IMN (group I) or MIPO (group M) for a closed extra-articular tibial shaft fracture (AO/OTA type 42) from June 2010 to May 2016 were retrospectively reviewed. The mean age was 51.16 (18~79) years, and the mean follow-up period was 22 (12~50) months. Bony union was achieved in all cases but one for each group - group I (35 cases) and group M (36 cases) (p > 0.05). Mean callus formation was observed in 12 (8 - 16) weeks in both groups (p > 0.05). There was no significant difference in operative time, hospital stay, bone healing, and the rate of complications among the two groups (p > 0.05). There was also no postoperative difference in functional evaluation between the two methods (p > 0.05). CONCLUSIONS: No discrepancy was found in radiological and clinical outcomes between IMN and MIPO for tibial shaft fractures. It can be concluded that both IMN and MIPO are equally effective treatment modalities for tibial shaft fractures.

BACKGROUND: There is abundance of literature regarding the treatment of tibial mid-shaft fracture, and intramedullary nailing (IMN) is described as the treatment of choice. However, problems such as malunion and knee pain are known disadvantages of this approach. Minimally invasive plate osteosynthesis (MIPO) technique is another treatment option for tibial mid-shaft fracture.The purpose of this study is to evaluate the clinical, radiological results, and complication rates of tibial mid-shaft fractures treated with MIPO technique. MATERIALS AND METHOD: Thirty-seven skeletally mature patients who underwent MIPO for a mid-shaft fracture of tibia (AO/OTA classification 42) from June 2016 to May 2018 were retrospectively reviewed. A total of 37 patients (12 females, 25 males) with a mean age of 52.7 years (range 28-78 years) were included. The clinical and radiological outcomes, such as the Jeju Lower Extremity Trauma Scale (JLETS), time to callus formation, time to bony union, and complications such as delayed union, malunion, nonunion, and infection were assessed. RESULTS: Bony union was achieved in all cases but one (36 cases). Average callus formation was observed in 10.7 (6.5-14.5) weeks. The average time to union was 19.8 (11.5-26.5) weeks. The average JLETS score was 46.9 (40-53) point. Malunion deformities were observed in 3 cases (8.1%). Two superficial infection cases all resolved spontaneously. There was no statistically significant difference in clinical and radiographic outcomes by different AO/OTA fracture types. CONCLUSION: The MIPO technique with locking compression plate provides stable fixation and satisfactory clinical and radiological results for mid-shaft fractures of tibia irrespective of the fracture type. Future study should aim to compare MIPO and IMN cases directly to clarify the differences and similarities between the two treatment modalities.
RESUMEN
Rotator cuff tear is a common cause of shoulder pain and disability in adults. Due to the various nature of progression of rotator cuff tears and the complex biomechanics of the shoulder joint, repair and treatment of large-to-massive tears are challenging for many surgeons. Despite the recent popularity of reverse total shoulder arthroplasty as a treatment option for large-to-massive irreparable rotator cuff tears, biological and mechanical repair augmentation has also shown promise as a viable treatment option. The purpose of this study was to briefly summarize and review current studies on the assessment and arthroscopic treatment of large-to-massive rotator cuff tears, whether repairable or irreparable, to aid in developing a consensus on future treatment directions.
