Comparison of static and dynamic biomechanical measures in military recruits with and without a history of third metatarsal stress fracture
Clinical Biomechanics Volume 21, Issue 4 , May 2006, Pages 412-419

Background
For Royal Marine recruits in training, the third metatarsal is the most common site for stress fracture. Previous evidence regarding biomechanical factors contributing to metatarsal stress fracture development is conflicting, possibly due to the lack of differentiation between the metatarsals. The present retrospective study compares static anatomical characteristics and dynamic biomechanical variables for Royal Marine recruits with and without a history of third metatarsal stress fracture.

Methods
Ten Royal Marine recruits with a history of third metatarsal stress fracture were compared with control subjects with no previous stress fracture occurrence. Selected static anatomical variables were measured to describe the ankle and subtalar joints. Peak ankle dorsi-flexion and rearfoot eversion were measured during running. In addition, peak vertical and horizontal ground reaction force variables were compared for the two study groups.

Findings
No significant differences in static anatomical variables were identified between study groups. During running, peak rearfoot eversion was found to occur significantly earlier for the stress fracture group than for their matched controls, suggesting an increase in time spent loading the forefoot. The peak applied resultant horizontal force during the braking phase was directed significantly more laterally for the stress fracture group. In addition, the peak magnitude of resultant horizontal force applied during the propulsion phase was significantly lower for the stress fracture subjects.

Interpretation
The findings of this study highlight the importance of including dynamic biomechanical data when exploring variables associated with the development of third metatarsal stress fracture and indicate that successful interventions to reduce the incidence of this injury are likely to focus on forefoot function during braking and propulsion.

Fourth Metatarsal Base Stress Fractures in Athletes: A Case Series.
Rongstad KM, Tueting J, Rongstad M, Garrels K, Meis R.
Foot Ankle Int. 2013 Feb 5.

Background:Metatarsal stress fractures account for approximately 28% of all stress fractures reported in the literature. Second and third metatarsal stress fractures are most common, followed by fractures of the fourth and fifth metatarsal. Reports in the literature suggest that proximal fourth metatarsal stress fractures have the same propensity for delayed healing and nonunion as do fifth metatarsal stress fractures. There is a paucity of literature on operative management of fourth metatarsal fractures. This study reports the results of operative management of fourth metatarsal stress fractures in athletes.

Methods:A retrospective review with prospectively collected data was undertaken to evaluate utility of operative care of fourth metatarsal stress fractures in an athletic population desiring early return to sports. Eleven athletes over a 13-year period were enrolled with proximal fourth metatarsal stress fractures. The American Orthopaedic Foot & Ankle Society (AOFAS) Midfoot scores were obtained pre- and postoperatively. Midfoot alignment, including the presence or absence of metatarsus adductus, radiographic time to healing, and time to return to sports were also recorded.

Results:All patients were treated with operative open reduction and internal plate fixation with calcaneal autograft. Four of the 11 patients had metatarsus adductus. All had evidence of radiographic healing prior to return to activity, all returned to sports at an average of 12 weeks post surgery, and all would choose surgery again given the same injury. The AOFAS Midfoot scale improved from an average of 55 preoperatively to 94 postoperatively (P < .001)

Conclusion:Our study suggests that operative repair of fourth metatarsal stress fractures hastens time of healing and return to sports in athletes. It also supports the theory that there is a correlation between metatarsus adductus lateral metatarsal stress fractures
