In baseball, especially at the beginning of the season, there is an increase in elbow problems amoung young players. The most common elbow problem is the medial apophysitis named « Little Leaguer or Youth Pitcher Elbow ».

The elbow joint is composed of 3 bones : upper arm bone (humerus) and 2 bones in the forearms (radius and ulna). Muscles, ligaments and tendons keep the elbow joints together.

Little Leaguer Elbow

This injury occurs when repetitive throwing creates an extremely strong pull on the tendons and ligaments of the elbow. The pain felt to prominence inside the elbow.

« Pitcher’s elbow » can become serious if the case gets worse. Repeated pull can tear ligaments and tendons of the bones. The tear can take tiny pieces of bone like when a plant takes piece of the soil when it uprooted. This can destabilize bone growth, which can create a deformity.

Symptoms

« Pitcher’s elbow » can cause pain in the elbow. If any of these symptoms occur, it’s recommended to stop the throws :

  • Elbow pain
  • Decreased movement amplitude
  • Locking or snagging in the elbow joint

Treatment

Elbow injuries by lanching movements can become complicated cases, if they’aren’t treated.

Non-surgical treatment

Younger children respond better to non-surgical treatment :

  • Stop throwing because continuing to do this can create major complications and may reduce a child’s ability to remain active in a throwing sport.
  • Use an ice bag to decrease swelling
  • If the pain continues after a few days of complete rest in the affected area or if the pain reoccurs when the throwing starts, stop the activity again until the child is treated.
  • Improve the technique of launched

Surgical treatment

Surgery is sometimes necessary for serious injuries, mainly for girls older than 12 years old and boys older than 14 years old.

Depending on the child’s injury, surgery may includes bone fragment removal, bone grafting or reattaching a ligament back to the bone.

Recovery time

The recovery time depends on the age of the athlete and the severity of the injury. If the injury detected early and the modification of the activity begins, there will be little time required for the athlete to start the sport again.

However, if the athlete continues to play despite the pain and other symptoms, it will take several months to heal the injury. Or it’s possible that the injury becomes permanent.

Prevent

The recommendation for a child to be safe is 15 for 8-10 years old, 100 for 11-12 years old and 125 for 13-14 years old. This involves training and competitions. To avoid pitching injury, young pitchers should play 3-4 inning each game.

SLAP Tears

slap tear anatomy shoulder

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

SLAP is an acronym for superior labrum anterior to posterior. The labrum is a rim of tissue that adds depth to the bony socket of the shoulder. The superior or « top » portion or the labrum is important and frequently injured because the biceps attaches to this region.

How

SLAP tears happens because of physical activity with repetitive overhead movements or physical shock. Tears created because of overhead movements are common among athletes as basball pitchers or tennis players. Tears created due to physical shocks are often a fall on a hand stretched with the arm over the head or fall directly on the shoulder.

Diagnosis

slap tear anatomy shoulder

SLAP tears are very difficult to diagnose only with a physical exam because of different shoulder problems. Using a MRI with or without contrast helps a lot.

Treatment

The first step is to do a nonsurgical treatment. While the SLAP tear likely will not heal, a study confirmed that many have improvement of symptoms and function. If nonsurgical treatment (such as physical therapy) isn’t successful, surgery is being considered.

Surgery is usually done arthroscopically and involves reattaching the torn labrum to the top of the cavity. Generally, bone anchors loaded with sutures are inserted into the top of the cavity. The sutures are passed through the torn area of the labrum. The sutures are tied, which brings the torn labrum to the bone.

Prevention

Although it’s difficult to avoir acute SLAP tears, it’s possible to prevent chronic tears, especially with athletes who make overhead movements, maintaining balance in the shoulder.

Exercices that strengthen the muscles around the shoulder blades and exercises that stretch posterior shoulders are recommended to reduce the risk of SLAP chronic tears.

Rotator Cuff Tears

rotator cuff tear anatomy shoulder

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

Rotator cuff is a group of 4 muscles and their tendons that together form a « cuff » around the head of the humerus (upper end of the arm). The 4 muscle, originate from the scapula (shoulder blade), are upraspinatus, infraspinatus, subscapularis and teres minor. Tendons of each muscle fit on the humerus tuberosity.

Rotator cuff’s functions :

  • Lift the arm

  • Turn the arm

  • Stabilize the humerus in the joint

Causes

rotator cuff tear anatomy

The causes of a rotator cuff tear can be an acute injury such as a fall or because of chronic wear with tendon degeneration. For people over 40 years old, the pinching of the tendon on the underside of the scapula may participate in tearing.

Diagnosis

Diagnosis of rotator cuff tears is based on an examination and/or diagnosis study such as a MRI (magnetic resonance imaging) to confirm the diagnosis. Diagnosis early on in the first symptoms and rotator cuff’s treatment can help to boost the treatment’s results.

Treatment

Goals treatment are to relieve pain and restore strength to the injured shoulder. Several tears in rotator cuff can be treated without surgery. Anti-inflammatory drugs, steroid injections and physical therapy can all be beneficial in treating the symptoms of a tear in the cuff.

Even though a full-thickness tear needs to be cured with surgery, it’s possible to use non-surgical treatments to have a satisfactory function in some cases.

Surgery

rotator cuff tear anatomy surgery

Surgery is recommended if there is persistent pain or shoulder weakness that doesn’t improve with non-surgical treatment. Often patients who have surgery indicate nocturnal pain and difficulty using the arm for lifting and reaching. Many will indicate persistent symptoms despite several months of treatment and limited use of the arm.

Surgery is also recommended for active people who use the arm for overhead work or sports.

Surgical options

The type of repair performed is based on the findings at surgery. A partial tear my necessarily only a trimming or smoothing procedure called a debridment. A full-thickness tear with the tendon torn from its insertion on the humerus is repaired directly on the bone.

3 techniques are used for rotator cuff repair :

  • Open repair (through a traditional incision)

  • Mini-open repair (partially assisted by a camera view, with a smaller incision)

  • Arthroscopic (performed with only a small camera inserted through multiple small puncture wounds)

Recovery and rehabilitation process

Whether for the treatment of non-surgical and surgical rotator cuff tear, rehabilitation has a very important role. Usually recovery is at least 6 months or more depending on the extent of the tear.

When there is a tear, there is frequently a loss of shoulder movement. An exercise or physical therapy program is needed to restore strength and improve shoulder function.

Although surgery repairs the defect of the tendon, the muscles around the arm remain weak and an important effort is necessary in the rehabilitation so that the procedure is a success. After surgery, a complete re-education can last several months.

Meniscal Tears

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

Meniscus tear

meniscus tear

Meniscal tear is one of the most common knee injuries in athletes. This is caused after a contact injury or a traumatic twist. The meniscus is a wedge-shaped cartilage that provides a cushion in the medial and lateral portion of the knee joint and acts as a « shock absorber ». It’s located in the area of joints contact to prevent the bones rub between them because of the bodyweight. It’s hard and rubbery to help cushion the joints and keep the knees stable.

It’s important to also know that the meniscus helps to nourish the knee by facilitating the diffusion of joint fluid. With this injury, athletes can experience acute pain with a swelling and often a catching or locking sensation.

Diagnose

A meniscus injury can be diagnosed on the basis of the story that the patient provides and a physical examination of the knee.

An orthopedic surgeon my also use other techniques to further diagnose such as magnetic resonance imaging (MRI), which gives a 3-dimensional image of the inside of the knee joint. In some cases, a surgeon can perform an arthroscopic inspection of the articulation, this is a minimally invasive surgical procedure.

Treatment

knee brace

A small meniscus tear can be treated with rest, ice and anti-inflammatory medications. When a meniscus tear causes a significant loss of movement or catching, the appropriate treatment is often a surgical operation. Depending on the location and type of tear, the treatment may be a simple arthroscopy to remove the torn fragment. Depending on how quickly the inflammation disappears, athletes can return to a full activity after a week or months.

For athletes with a repairable tear, sutures are used to sew the meniscus. In this situation, the knee is braced for 6 weeks. These athletes take at least 3-6 months to back to their activities but maintain the full cushion in their knees.

Prevention

There is not really any way to prevent a meniscus tear apart from a conditioning program to try to prevent an acromioclavicular ligament (ACL) tear and knee instability.

Stats

Women have meniscus tears more often than men and at an earlier age. These tears are often associated with an acromioclavicular ligament injury (ACL)

There are some variables of meniscus tears can be repaired and despite repair, they aren’t always heal. But arthritis can be avoided in the majority of cases when repair is successful. One study shows that 60% of patients who undergo meniscectomy (partial elimination) had some degree of progressive arthritis.

Acromioclavicular Joint Injury

acromioclavicular joint injury

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

Acromioclavicular joint is a joint between the clavicle and the scapula. Acromion is a continuation of the scapular spine and hooks over anteriorly. It articulate with the clavicle (collar bone ) to form the acromioclavicular joint.

Problems types

The most common problems are arthritis, fracture and separation. Arthritis is characterized by a loss of joint’s cartilage. Arthritis of acromioclavicular joint is common with weight lifter, especially with bench press and a little less with shoulder press. When there is a problem with the rotator cuff, it’s possible that there is also acromioclavicular joint’s arthritis.

Acromioclavicular separation

acromioclavicular joint injury type grade

When there is an acromioclavicular joint separation, it means that the ligament that connects the acromion and clavicle is damaged and that the 2 structures don’t align properly. Separation’s state can be weak or severe, that is why there is a system of « grade » according to which ligament is torn and the severity of the tear.

Grade I Injury – This is the weakest damage and the acromioclavicular joint is still aligned.

Grade II Injury – This is an average damage. Ligaments are only stretched but not fully torn. In case of stress (physical effort), the acromioclavicular joint becomes painful and unstable.

Grade III Inury – This is a serious damage. Ligaments are completely torn and the collar bone is no longer attached to the scapula, which creates a visible deformity.

Treatment of acromioclavicular joint arthritis

If the rest, ice, medications and change of the training program (changing the exercises) don’t work, the next step is a shot of cortisone. A shot of cortisone in the joint may have calmed the pain and may be permanently swollen. As each individual is unique, the effects may vary and it’s possible that it doesn’t swell permanently.

If non-surgical methods fail, it’s possible to perform a surgical operation. The pain is localized at the bones end that make contact with each other and the goal of the operation is to remove some of the end of the clavicle. This ambulatory surgery can be done with a small incision of 1 inch (2.5 cm) long or with the arthroscopy technique with 2-3 incisions. The results and recovery of these 2 surgical techniques are about the same. Most patients have a full movement by 6 weeks and can return to do sport by 12 weeks.

Treatment for acromioclavicular separation

Separation can create very painful injuries, so the first thing to do is to decrease the pain. Hold the arm in a sling, put ice and pack the shoulder for 20-30 minutes every 2 hours as needed. Acetaminophen and non-steroidal anti-inflammatory medications can also help calm the pain.

When the pain begins to subside, it’s important to move the fingers, wrists and elbow (and eventually the shoulders) in order to avoid having stiff or « frozen » shoulder. The length of time needed to regain complete movement and function depends on the severity or injury’s grade.

Recovery from Grade I acromioclavicular separation usually takes 10-14 days while Grade III takes 6-8 weeks.

When surgery

Grade I and II separations require very rarely surgery. With a Grade III injury, after surgery, it’s possible to have full body physical activity with some restrictions.

Statistics

  • More males than females suffer acromioclavicular joint injuries

Anterior Cruciate Ligament Injuries

anterior cruciate ligament injury tear

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

Knee is the largest and most complex joint of the body. There are 4 primary ligaments (with their muscles and tendons) and secondary ligaments for the knee to function properly. Here are the ligaments of the knee : there are 2 ligaments on the side the medial collateral ligament (MCL) and the lateral collateral ligament (LCL) and two crossed ligaments in the center of the knee, the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL).

Anterior cruciate ligament connects the front top part of the shine bone to the back bottom part of the thigh bone and keeps the shin bone from sliding forward.

anterior cruciate ligament

Injury

anterior cruciate ligament injury tear

There are several ways to have an injury to the anterior cruciate ligament :

  • The injury can be done because of a direct hit on the knee, which often happens in team sport.

  • The injury can be done without contact with an object in a situation where the knee forced to be in a abnormal position, which causes a tear in one or more ligaments of the knee. Or when an athlete in the race change direction. Or when an athlete make a hyperextend of the knee when landing a jump, which often happends in agility sports.

Diagnostic

In the majority of cases, the doctor is able to identify what is the injured ligament. But the knee can also be injured at the joint on the surface and in this situation, it’s more difficult to diagnose because of knee swelling. To make an accurate diagnosis, it will be necessary to use a MRI scan or arthroscopy.

Prevent

There are several fast, powerful movements that lengthen (eccentric phase) and shorten (concentric phase) a muscle. These prevention programs are for injuries without contact. These exercises are to improve the nerves/muscle control of the knee. These prevention programs use plymetrics, balance and strength/stability exercises.

Plymetrics

It’s a fast, powerful movement that lengthens (eccentric phase) and shortens (concentric phase) a muscle. The concentric phase increases the muscle power. Here is an example, an athlete who jumps from a box and immediately jumps into the air after touching the floor.

Balance

Balance exercices are done with the wobble or balance board. It’s also possible to perfom exercices by throwing a ball with a partner while balancing on one leg.

Strength/stability

To improve single-leg core strength and stability, there are excellent exercices such as jumping and landing on one leg with the knee flexed and momentarily maintaining this position.

Surgical treatment

In the past, there was a technique that consisted of stitching the ligament together but it was rarely successful. Currently, the technique involves reconstructing the anterior cruciate ligament by building a new ligament from tissue taken from one of the other tendons around the knee or from on organ donation. This tissue passed through drill holes in the thigh bone and the shin bone, and then ancored in place to create a new anterior cruciate ligament. Over time, this transplant becomes mature and becomes a new living ligament in your knee.

Recovery

recovery

Rheabilitation of the knee after the reconstruction of the anterior cruciate ligament requires time and work. To have a complete function, this can last between 6 weeks and 6 months depending on the severity and level of activity. Rehabilitation rate may take time depending on the specific requirements of the sport/physical activity of the individual.

The overall success rate of the anterior cruciate ligament surgery is very good. A lot of study show that more than 90% of patients are able to return to sport without symptoms of knee instability. It’s true that some patients complain of stiffness and pain after surgery, that is why it’s necessary to make an aggressive rehabilitation until the new surgical technique to reduce these problems.

Statistics

  • One of the most commonly injured ligament in the knee

  • Female athletes participating in basketball and soccer are 2-8 times more likely to suffer anterior cruciate ligament injury.

  • Athlete who suffer anterior cruciate ligament injury at increased risk of arthritis development later in life.

High Calf And Low Calf

high calf low

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

I think you noticed that there are big differences in the shape of the calves. These morphological variations are due to the evolutionary adaptations to the climate that occurred during the first human migrations.

It’s common to see African blacks peoples with proportionally long legs with a sagging plantar arch of the foot (flat foot) and a long calcaneus. This bone conformation of the leg and foot provides excellent leverage in the ankle and minimal triceps surae muscle (calf muscle is short, thin and high with a long tendon) for powerful extension of feet to walk.

It’s common the see Nordic people with short legs with a pronounced plantar arch of the foot and a short calcaneus. This bone conformation of the leg and foot requires a massive and uneconomic triceps surae muscle who get down very low to do an extension of feet to walk.

high calf low anatomy

This type of massive and long calf is actually an adaptation to cold climates to keep body heat. This prevents legs from cooling too much during the freezing cold to prevent amputation of the legs. These massive and long calves are seen as aesthetic (bodybuilding competition) but they’re less suitable for running and more vulnerable to muscle tears.

Massive and long calves requires more and careful warm-up and it’s important to do stretching exercises before and after an intensive workout of calves.
