Purpose: Shoulder replacement becomes more indicated in complex fractures of the humeral head. Indications depend on some factors especially age and fracture’s pattern. The aim of our study is to compare the functional results of both reverse shoulder arthroplasty (RSA) and hemi-arthroplasty (HA) in complex proximal humerus fractures. Materials and Methods: Fifty-two shoulder arthroplasties (20 reverse shoulder arthroplasties, 38 hemiarthroplasties), were reviewed retrospectively, between January 2010, and December, 2015. Preoperative, operative, and postoperative evaluations were achieved based on medical observations. At last follow-up, functional outcomes were established according Constant-Murley Score and American Shoulder and Elbow Surgeons (ASES) score. Complications rates were well-defined and compared between the study groups. Results: The mean of follow-up was 41.5 months. Comparing the study groups, reverse shoulder arthrosplasties were significantly older (mean age: 76.3 versus 66). These fractures occur more in women (70% versus 57%). At last follow-up, functional outcomes were better in reverse shoulder arthroplasty group (Constant-Murley Score 76 versus 59;ASES score 56 versus 41). The mean anterior elevation and external rotation were better in reverse shoulder arthroplasty respectively (110°versus 88°;28° versus 19°). Revision was more required in hemiarthroplasty group than reverse shoulder arthroplasty group. Conclusion: Reverse shoulder arthroplasty seems to improve functional outcome at intermediate and long-term of follow-up of proximal complex humeral fractures on comparison to hemiarthroplasty.

Patellofemoral Outcome after Medial Unicompartmental Knee Replacement: A Retrospective Study of 25 Cases

Introduction: Osteoarthritis and impingement, in patellofemoral compartment after partial arthroplasty, have been rarely reported. The purpose of our study was to evaluate outcome at long-term follow-up. Methods: We have reviewed retrospectively twenty-five unicompartmental arthroplasties. The medial parapatellar approach was used in all cases. Patients have been evaluated with regard to patellar impingement and osteoarthritic changes revealed by radiographs. The mean follow-up was 10.4 years. The clinical scoring system of the Knee Society and specific questions regarding patellofemoral symptoms were used for functional outcome. Patellofemoral complications such as osteoarthritis, impingement and the position of the femoral component were diagnosed on X-ray views of the knee. Results: At the final follow-up, fifteen knees revealed lateral patellofemoral osteoarthritis and four knees had patellofemoral impingement. Excepted of two cases, all knees with patella impingement did not revealed degenerative modifications. Anterior pain of the knee was noted more frequently in knees with patellar complications. Patellar impingement was considered the first cause of knee pain, more than knees with degenerative modifications. Only one revision surgery was indicated in front of patellofemoral conflict. The occurrence of patellar impingement depends on the surgical procedure. The anterior position of the femoral component seems to increase the frequency of such complication. Conclusion: Several degenerative modifications may occur in the patello-femoral compartment following partial knee arthroplasty. Patellar impingement and total knee arthritis are the most reported modifications. Functional outcome may be affected progressively when these changes become obvious. Patellar impingement is the major cause of knee pain and needs revision.

Tuberculosis Arthritis of the Sternoclavicular Joint

Tuberculosis remains a public health problem in developing country particularly in Tunisia. Bone location of tuberculosis infection is increasing and is often misdiagnosed due to the weakness of clinical presentation in early stages. Sternoclavicular joint tuberculosis is rare and unusual location of this disease. However, antibiotherapy and surgical debridement is still the basis of treatment. We report a case of sternoclavicular joint tuberculosis with a follow up of four years. The patient was treated surgically and put under antibiotherapy during twelve months. The site was sterilized. We report this case to show that debridement and antibiotherapy still efficient in tuberculous bone affection no matters the location.
