A stress fracture occurs when a bone breaks after being subjected to repeated
tensile or compressive stresses
, none of which would be large enough individually
to cause the bone to fail.
From an etiologic standpoint, two types of stress fractures are encountered: fatigue fractures and insufficiency fractures. Fatigue fracture A fatigue fracture is caused by the application of abnormal muscular stress or
torque
to a bone that has normal elastic resistance.

Stress fractures: an analysis of 250 consecutive cases. Radiology 1969;92:481-486. Insufficiency fracture An insufficiency fracture occurs when the mechanical strength of a bone is reduced to the point that a stress, which would not fracture a healthy bone, breaks the weak one. The condition that causes reduced bone strength typically does so throughout the skeleton (eg, osteoporosis, osteomalacia, or osteogenesis imperfecta), but may be more localized (eg, demineralization in a limb due to disuse). Pentecost AL, Murray RA, Brindley HH. Fatigue, insufficiency, and pathologic fractures. JAMA 1964;187:1001-1004 Etiology and Pathophysiology:
Wollf's law

In most activities of daily living, when the force is removed, the bone elastically rebounds to its original position. The force that a bone can endure and
still rebound back to its original state
without damage is within the elastic
range. (A1 to A2)
Forces that exceed a critical level
above the elastic range are in the
plastic range. (B)
Once forces reach the plastic range, a
lower load causes greater
deformation, permanent deformity
occurs as the result of microfractures
within the bone (C); it is at this level
that forces summate to permanently
damage the bone. (D)
Richard H. Daffner and Helene Pavlov. Stress Fractures: Current Concepts. AJR 159:245-252, August 1992. Etiology and Pathophysiology:
Two competing, but not mutually exclusive, theories may explain the
development of stress fractures
Remodeling theory holds that during the initial increase in exercise activity, the skeleton
experiences repetitive loading in its role of providing internal support to counteract the force of
gravity and in forming levers for motion.
This damage is a natural phenomenon and is typically of little consequence as bone is capable
of self-repair through targeted remodelling.
Determinants of damage formation in bone include the magnitude and rate of introduction of
applied loads, and the absolute number of loading cycles.
Damage is threshold related, such that strain magnitudes above a certain level result in its
formation. Influencing the damage formation is the rate at which the strain is introduced.
Strains that are introduced over shorter periods result in considerably greater damage formation.
The interaction between strain magnitude and rate ultimately reduces the number of loading cycles a bone can withstand before fatigue failure. During this initial increase in exercise activity period, osteoblastic activity lags behind
osteoclastic
activity by a few weeks, resulting in a period during which bone is more susceptible
to accumulate damages.
Etiology and Pathophysiology:
Two competing, but not mutually exclusive, theories may explain the
development of stress fractures
Muscular imbalance theory emphasizes bone as a dynamic architectural substance that
responds to changes in the muscular activity imposed on it.
Increased muscular activity results in an increase in the strength of both muscles and bone. Conversely, a decrease in activity or muscular atrophy results in muscular and bony atrophy. Under normal circumstances, the muscles tone up at a faster rate than the bones do.
Strong and repetitive stress on bone at the insertion point of muscles may provoque focal
bending stresses
beyond the ability of the bone to tolerate.
Fatigue of opposing muscle groups that usually prevent one group of muscles from having an
overexerting effect on the bone may result in a further imbalance and lead to bone failure
Etiology and Pathophysiology:
Additional factors contribute to the increased muscular pull, producing overload on stressed
bones

poor posture, typically causes a change in the center of gravity for which the body
compensates. This increases the effect of direct muscular pull and also leads to fatigue of
opposing muscle groups.
the operating conditions in which the activity is practiced.
To a runner, changes in terrain, running surface, or equipment can cause a change or
an increase in muscular pull on the bones of the leg.
 Changing from a grass surface to a hard surface may lead to protective curling of the feet to cushion the footfall. Running up or down a hill increases the forces by a factor of seven.

The patient must be questioned closely about the sequence of events leading to the sudden onset of pain in the affected limb Stress fracture should be suspected in persons with a drastic recent increase in
physical activity or repeated excessive activity with limited rest
Even conditioned professional athletes may have stress fractures when they have
broken training or decided to increase the amount of effort involved in performing
their particular athletic feat
Many middle-aged and elderly persons are now engaged in this activity, a fact that
accounts for the increasing number of insufficiency-type stress fractures that are
encountered.
Recreational walking is a low-impact activity with excellent aerobic cardiovascular effects. Diagnosis: History
 Pain is a common presenting symptom that can vary by location, such as knee pain with a proximal tibial injury, hip pain with a femoral neck injury, or groin pain with a pelvic fracture  Early on, the pain typically is mild and occurs toward the end of the inciting
activity (81%)

 Subsequently, the pain may worsen and occur earlier, limiting participation in sports activities  While rest may provide transient relief of symptoms in the early stages, as the
stress injury progresses, the athlete's pain may persist even after cessation of activity  Night pain is a frequent complaint. H, Mattila VM, Kiuru MJ, Pihlajamäki HK.

Diagnosis: Physical examination
The hop test
single leg hopping produces severe localized pain is often used and cited in texts as a diagnostic test for lower extremity fractures no recent literature was found to validate its accuracy In some studies, a positive hop test was an inclusion criterion or a common finding (70% to
100%) in patients with presumed stress fractures
, but was also noted in nearly one-half
(45.6%) of patients with suspected medial tibial stress syndrome (shin splints).

REST protocol phase III

During the functional phase of the program, the athlete continues the phase II exercises and progresses to mobility and jumping activities in the pool before their initiation on dry land. Once the athlete can squat 1½ times body weight, higher-level plyometric training may begin. Zelko R et al. Sress fracture in athletes: diagnosis and treatment. Postgrad AdvSport Med. 1986;I-IX:1-20. Treatment Recommendations:
REST protocol phase III

The running portion of phase III is completed in a cyclic fashion that mimics bone growth. As bone is being resorbed in the first 2 weeks of activity, running is encouraged to promote the formation of trabecular channels (functional phase). In the third week, when the newly formed osteocytes and periosteum are maturing, running activity is decreased (rest phase). As the running program progresses to sprinting and sport-specific activities, the rest days between functional activities decrease, and the athlete is gradually prepared for the return to competition.

REST protocol phase III

Increasing activity
A good guideline is to increase activity no more than 15% to 20% per week.
A ‘‘walk-jog'' in which the injured person jogs the straightaways and walks the curves
of a track for 0.80 km
Once that distance is completed without pain, the injured person can begin walk-jogs
3 times per week
.
Distance is added in 0.80 km increments per week until the athlete can complete
3.22 km.
At this point, jogging begins for 1.61 km and increases by 0.80 km per week until
4.83 km or a goal distance commensurate with the person's activity is reached.

to summarize

 Despite different theories, clinical and research studies on the cause of MTSS II, the fact that the detailed structural cause is still unknown highlights the need for prospective longitudinal investigations. Etiology and Pathophysiology:
Cortical bone fatigue in MTSS II

The research on cortical bone cyclic testing, both in vitro and in vivo studies, provided invaluable data on the development of fatigue injury in cortical bone. Like TSFs, cortical bone microtrauma occurring in MTSS II is likely the result of tensile
failure
causing osteon debonding at the cement lines as the tibial microstructure is unable to
repair quickly enough through adaptive bone remodelling.
However, unlike a TSF, this microdamage clearly does not extend beyond the
microscopic lamellae structure
, at least in many cases, so that crack development is
arrested in MTSS II before a macroscopic partial fracture transversing the osteons occurs.

Aetiology and mechanisms of injury in medial tibial stress syndrome: Current and future developments. World J Orthop 2015 September 18; 6(8): 577-589. Etiology and Pathophysiology:
Does periostistis or cortical bone microtrauma
occur first in MTSS II?

Based on their MRI study of 14 patients with 18 symptomatic legs, Fredericson et al
postulated that periosteal oedema occurs prior to the formation of cortical bone

as only periosteal oedema was detected in their patients with the mild injuries while those with more severe injuries had both periosteal oedema and either a partial fracture, or marrow oedema indicating bone microtrauma. Etherington et al studied a cohort of 40 male military recruits over 10 wk of basic training, 26 of whom completed the training, and measured a number of parameters including the velocity of ultrasound in the heel. The authors found there was a mean decrease in the ultrasonic velocity from pre to
post training in recruits who completed the training uninjured

cortical bone microtrauma occurs prior to the development of any clinical
injury, and could be a precursor to periostitis.

*Pronated foot type *Cohort studies have identified altered kinematics in MTSS sufferers, which may partly explain the link between previous history of MTSS and future MTSS, but to date no prospective trial has identified a specific kinematic risk factor. Phil Newman et al. Risk factors associated with medial tibial stress syndrome in runners: a systematic review and meta-analysis. Open Access Journal of Sports Medicine 2013:4 229–241. Diagnosis: History
The most common complaint of patients with MTSS II is vague, diffuse pain of the
lower extremity, along the middle-distal tibia associated with exertion.
In the early course of MTSS II, pain is worse at the beginning of exercise and
gradually subsides during training and within minutes of cessation of exercise.
As the injury progresses, however, pain presents with less activity and may occur at
rest.

A comprehensive history should be obtained to evaluate: the athlete's weekly exercise routine and running mileage, intensity, pace, terrain, and
footwear, with careful attention to recent changes in training regimens.
training errors appear to be the most common factors involved in MTSS II, especially as
athletes attempt to do ‘‘too much, too fast''.
common training errors include a recent onset of increased activity, intensity, or duration. running on hard or uneven surfaces is also a common risk factor. Individuals with previous lower extremity injuries and running more than 30 km
per week are especially predisposed to overuse injuries of the lower extremity,
including MTSS II.

Weakness of core muscles is an important risk factor for lower extremity injuries.
Hip and pelvis muscle strength are an important link in maintaining control and proper mechanics between the ‘‘core'' and lower extremity. Core and pelvic muscle stability may be assessed by evaluating patient's ability to maintain a controlled, level pelvis during a pelvic bridge from the supine position, or a standing single-leg knee bend.

Imaging is usually not necessary for the diagnosis of MTSS II. However, if the patient fails to improve with conservative management, plain film
radiography
may be considered.
X-rays are usually negative within the first 2–3 weeks after the onset of injury. Mellion M, Walsh W, Madden C, Putukian M, Shelton G. The team physician's handbook. 3rd ed.

A triple-phase bone scan demonstrates evidence of a stress fracture with a diffuse,
longitudinal uptake along the posterior tibia, seen only on the delayed phase of the
scan.
Bone scans have been the gold standard for diagnosing stress fractures in the past, but now are often replaced by magnetic resonance imaging (MRI). Kortebein P, Kaufman K, Basford J, Stuart M.

MRI has many advantages over a bone scan and plane radiography. MRI is better
able to identify other soft tissue injuries.
MRI can show progression of injury in the tibia, starting with periosteal edema, progressive marrow involvement, and finally cortical stress fracture. With better accuracy, MRI can grade tibial injuries according to extent of involvement. Grading tibial injuries may help clinicians make more accurate recommendations for rehabilitation, though no literature data exist about MRI findings and specific return-to-play guidelines.

Footwear
Shoes should fit properly with a stable heel counter. Some physicians recommend alternating running shoes especially when one pair is wet, as this compromises the shoe's integrity. Runners should also change running shoes every 400–800 km, a distance at which
most shoes lose up to 40% of their shock-absorbing capabilities and overall support .
Athletes should seek out shoes with sufficient shockabsorbing soles and insoles,
as they reduce forces through the lower extremity and can prevent repeat episodes of
MTSS II.

Graded Running Program
The first four phases of the graded running program consisted of interval training in which duration was increased from 16 to 20 minutes and intensity increased from light jogging to a running speed where speaking became difficult. When "meters run at 10 km/hour" was between 0-400 meters, the athlete started the running program in phase one. When 401-800 meters could be run, the athlete started in phase two. When 801-1200 meters could be run the athlete started in phase three. When 1201-1600 meters could be run, the athlete started phase four. When 1600 meters or more could be run, athletes started phase five. In phases 5 and 6, continuous running was performed for 16 and 18 minutes, respectively, and the intensity was increased from light jogging to running at a speed where speaking became difficult. A new phase of the running program was commenced when a phase was finished without a pain score of 4 or higher on the 1–10 VAS. Training was performed three times a week, on non-consecutive days.

Return To Activity Phase

Modify the training routine
Decreasing weekly running distance, frequency, and intensity by 50% will likely
improve symptoms without complete cessation of activity.
Runners are encouraged to avoid running on hills and uneven or very firm
surfaces.
Synthetic track or a uniform surface of moderate firmness provides more shock absorption
and cause less strain on the lower extremity.
During this time, athletes can benefit from cross training with other low-impact
exercises
, such as
pool running, swimming, using an elliptical machine, or riding a stationary bicycle. Beck B. Tibial stress injuries: an aetiological review for the purposes of guiding management.

Return To Activity Phase

There is an approximate one month window after the patient returns to their activity where the chance of reinjury is great. Patients must realize their limits and be patient! Treatment Recommendations:
Conservative therapy - shock wave therapy

Non-randomized clinical trial studied the effect of radial ESWT in addition to a 12-week home training program, relative rest and ice appliance compared with a 12-week home training program, relative rest and ice appliance only,
radial ESWT in addition to an exercise home training program was found to
improve global perceived effect and severity of pain when compared with a home
training program only.

Non-randomized clinical trial studied the effect of a six-phase graded running program compared with the same running program with the addition of focused ESWT This study was performed in an athletic population.
focused ESWT in addition to a graded running program reduced time to
completion of a graded running program significantly more than a graded running
program alone.

Treatment Recommendations:
Conservative therapy
- Injections
Newer methods, such as dry-needling, autologous blood injection, platelet-rich plasma, and prolotherapy, seek to stimulate a local healing response in injured tissues. Some physicians have proposed injecting the spring and short plantar ligaments to treat laxity and poor mechanics of the foot arch, which are common factors contributing to hyperpronation. However, no RCTs have been performed with these different injection techniques for
MTSS II.

and various methodological shortcomings.

Surgical options

Surgery for MTSS II is usually reserved for recalcitrant cases who do not respond with conservative treatment. A ‘‘posterior fasciotomy'' is the common procedure performed.  This may include cauterization of the posteromedial ridge of the tibia. Surgical results are variable and not likely to cause complete resolution of symptoms but may improve pain and function. Intramedullary nail placement has been used for those with stress fractures in season. Detmer D. Chronic shin splints. Classification and management of medial tibial stress syndrome.
