Femoral Neck Stress Fracture of a Male, Healthy Marathon Runner - Case Report and Literature Review

Lateral femoral neck stress fractures: A case report

BACKGROUND

Sport-induced injuries particularly affect young, healthy, and active individuals. Running, a popular and accessible sport, can cause a wide range of injuries, including stress fractures. Stress fractures can occur during high-intensity training or competitions, especially among well-trained amateurs and professional athletes. Adequate diagnosis can be complicated by the typically young age, unremarkable medical history, and vital condition of the patient. Stress fractures present insidiously, and this is specifically the case with stress fractures of the femoral neck. Timely intervention is crucial to prevent progressive displacement, as this can damage the blood supply to the femoral head.

CASE SUMMARY

A 30-year-old male runner presented to our outpatient clinic with persistent pain 3 weeks after running a marathon. X-ray showed a complete lateral fracture of the left femoral neck, which was treated surgically with a dynamic hip screw.

CONCLUSION

It is essential for healthcare providers to be vigilant for the subtle symptoms of stress fractures to ensure timely treatment. Early recognition prevents complication and leads to a better prognosis.

Personality of marathon runners: a narrative review of recent findings

Participation in marathons has dramatically increased over the last few years. Marathon running has many proven beneficial effects, especially on cardiovascular health and fitness. Most research has focused on physiologic and pathophysiologic adaptations in connection with endurance exercise. Nevertheless, marathon running also has a major impact on psychological aspects and positively influences mental health, which has only recently attracted research interest. The present narrative review aimed to review the personality traits of marathon runners with an emphasis on recent literature. Marathon runners show a distinct personality and highly characteristic personality traits needed to successfully finish such a demanding race, i.e., a strong sense of vigor, self-sufficiency, and intelligence as well as low scores in anger, fatigue, tension, and depression. Furthermore, personality differences are detectable between runners of different sexes, ages, and performance level groups. This has significant clinical implications for athletes, coaches and competition organizers, as these groups show different patterns of personality traits. Future studies should focus on changes in cognition and mood states pre-, during, and post-endurance events, as well as during training periods. Large-scale studies comparing personality differences by sex, age, and performance are also important for better clinical guidance. See also the graphical abstract(Fig. 1).

Treatment and Rehabilitation Approaches for Stress Fractures in Long-Distance Runners: A Literature Review

Stress fractures (SFs) result from repetitive mechanical stress on bones, leading to an imbalance in osseous tissue adaptation and resulting in cortical fractures. The majority of SFs occur in the lower limb due to excessive mechanical loads. Long-distance runners are highly susceptible to SFs, especially when there is a significant increase in the load or intensity of their activity. Various intrinsic and extrinsic factors contribute to the development of SFs. Common SF locations in long-distance runners include the tibial shaft, femur, metatarsal, and pelvic region. Diagnosis may be delayed due to mild symptoms and unremarkable imaging tests. However, the chronicity and recurrence of misdiagnosed SFs may lead to debilitating complete fractures that are even more challenging to treat. In this review, we present data revealed from published case reports and case series studies obtained through PubMed and Embase databases focusing on the management of SFs in long-distance runners and correlate treatment outcomes with rehabilitation and return to high-level athletic performance.

Femoral neck stress fracture return to activity and the effect of metabolic dysfunction on recovery: A systematic review

Background

Femoral neck stress fractures are rare fractures traditionally found in athletes and military personnel. There is limited literature on return to activity.

Objectives

To report return to activity rates and times, and long-term outcomes for femoral neck stress fractures reported in the literature. To examine the effects of bone metabolic dysfunction and surgical management on return to activity following FNSF.

Research design & methods

A systematic literature review of case reports and case series on adults with femoral neck stress fracture that were diagnosed by gross fracture line on X-ray or gold-standard diagnosis with MRI was conducted. Initial search was limited to articles published from January 1997 to Jan 2023 listed in Medline, Embase, and Scopus. Additional articles were manually added via search of retained paper sources. Patient demographics, fracture type, return to activity time, and surgical vs non-surgical treatment modality were collected. In addition, long-term outcomes and metabolic effects, if reported, were abstracted.

Results

A total of 40 case reports or case series were retained. 123 stress fractures of the femoral neck from 103 patients were compiled. Of the 103 patients, data on return to activity at least one year following treatment was available for 53 patients. 71% (37/53) of those with long-term follow-up information returned to full pre-injury activity. 24% (13/53) at long-term follow-up had functional recovery but did not return to pre-injury activity due to residual pain. 4% (3/53) had disabling pain. Metabolic workup information was available for 36 patients.

Conclusion

Long-term follow-up and return to activity information following FNSF treatment are not commonly reported. Based on the available data, outcomes appear benign with most returning to full activity. There is a clear need for standardization of follow-up periods and hip function measure after FNSF treatment. Additionally, a sizable proportion of FNSF occurred in a new population of low-activity individuals with abnormal bone metabolism, which warrants further exploration.
