    Stress fractures are caused by repetitive microtraumas that occur during unusual or increased activities. Clinical suspicion is essential for the diagnosis. A twenty-years old soldier was presented with bilateral knee pain and restriction of knee movements after a period of training for ceremonial march. Although plain X-rays were normal, scintigraphy and MRI revealed stress fractures at metaphyseal region of both tibias. History of a patient presenting with persisting joint or bone pain after an unusual repetitive activity should be delicately inquired. Typical history, although pain might be localized to unusual sites, should raise the suspicion of a stress fracture

    PURPOSE: The objective of this study was to evaluate the rate, associated risk factors and outcome of insufficiency femoral neck fractures following arthroscopic femoral neck osteochondroplasty for femoroacetabular impingement. METHODS: Between 2005 and 2009, a consecutive series of 376 arthroscopic femoral osteochondroplasties for femoroacetabular impingement were performed and analysed. Seven postoperative fractures were found and comprise the fracture group. The amount of femoral head-neck bone resected as assessed on follow-up cross table lateral views, as well as age, gender, height, weight and BMI, was compared between the fracture group and the entire collective. Subjective outcome was recorded using the WOMAC score. RESULTS: Seven fractures (1.9 %) were identified. All occurred in males at an average of 4.4 weeks postoperatively and were considered insufficiency fractures. The fracture group had a significantly higher mean age (p = 0.01) and height (p = 0.013). Within the fracture group, alpha angles were lower (p = 0.009) and resection depth ratios were higher (p < 0.001). The femoral offset was significantly higher (p = 0.016) in the fracture group and in male patients (p < 0.001). The cut-off value for resection depth ratio on cross table lateral radiograph was 18 % of the femoral head radius. After a mean follow-up of 20 months, an inferior WOMAC (p = 0.030) was recorded in the fracture group. CONCLUSION: Femoral neck insufficiency fractures were identified in 1.9 % of our arthroscopic femoral osteochondroplasty cases. Significant new pain following a period of satisfactory recovery after arthroscopic femoral neck osteochondroplasty should alert the surgeon to the possibility of this complication. If a resection depth ratio of more than 18 % is recognized on the postoperative cross table lateral view, particularly in male patients with a high femoral head-shaft offset, the risk of postoperative insufficiency fracture is increased. This study not only defines the complication rate, but also identifies associated risk factors and determines the influence on the postoperative subjective short-term result. Important information for both the patient and orthopaedic surgeon is provided and may have a direct consequence on the postoperative protocol. LEVEL OF EVIDENCE: IV
