Tennis elbow or lateral epicondylitis is a condition in which the outer part of the elbow becomes sore and tender. The forearm muscles and tendons become damaged from overuse -repeating the same strenuous motions again and again. This leads to inflammation, pain and tenderness on the outside of the elbow. Any activity, including playing tennis, which involves the repetitive use of the extensor muscles of the forearm can cause acute or chronic tendinitis of the tendinous insertion of these muscles at the lateral epicondyle of the elbow. It is a common pathology of both athletes and non-athletes affecting 1 to 3% population at large. Tennis elbow is seldom observed in subjects under the age of 25 years and black people are apparently affected less frequently than the whites. Tennis elbow has been reported to be four times more common in the fourth decades of life. Currently available conservative treatment methods include acupuncture, ultrasound therapy, steroid injection, counter force bracing, cross friction massaging. Some of these treatment modalities have no scientific basis. The most successful non operative treatment consists of avoidance of overuse counterforce bracing to relieve the insertion of extensor tendons, steroid injection into the affected area and stretching exercises.

Background: Various implants have been developed to stabilize intertrochanteric fractures from the earlier days. Recent techniques of closed reduction and internal fixation by intramedullary device are more popular and have given favorable results, as these devices are bio-mechanically more stable, cause less trauma to the soft tissues and also preserve the fracture hematoma. This study was conducted to know the functional outcome, technical complications, and factors predicting the failure of the implant by treating intertrochanteric fractures by proximal femoral nailing (PFN). Methods: From October 2017 to December 2019 we treated 60 patients with stable and unstable intertrochanteric fractures with PFN. Mean age of the study population was 64.10 years. Those who had bilateral hip fractures, patients with pathological fractures, who underwent previous hip surgery for the same or opposite side are excluded from the study. Results: 81.7% patients had excellent and good outcome and 18.3% patients had fair and poor outcome at the end of 1-year follow-up. Fair and poor results were observed in patients who belonged to higher age group (p=0.001), associated with co-morbid conditions (p=0.01) and who had complications.4 patients developed complications related to the implant (3 -proximal screw cut-out and 1 z-effect). Complications were observed in patients in whom fractures were fixed with high values of tip apex distance (TAD), calcar referenced tip apex distance (CalTAD), Parker's ratio index (p<0.001). Conclusion:We are concluding that the age and co-morbidities are the important factors which affect the functional outcome and TAD, CalTAD, Parkers' ratio index are important factors which predict the failure of the implant. Gender, laterality and mode of injury, Type of fracture will not affect the final outcome.
