Clinical Photograph – Rupture of Proximal Biceps Tendon

Ruptured Distal Biceps Tendon

Ruptured Biceps Tendon-The Popeye Muscle

Rupture of the proximal head of the biceps tendon involves one of two heads of the biceps tendon. This condition usually occurs in older individuals and is caused by degenerative changes.

Symptoms are

  • Sudden pain
  • Audible snap i
  • Bulge in their arm at the biceps muscle also referred to as a “Popeye Muscle”

Complications of Acute Shoulder Dislocation

The dislocation of the shoulder requires a sufficient amount of trauma to occur. The same trauma can cause injury to structures around the shoulder joint and lead to immediate and long term complications

Bony Complications

  • Fractures of the humeral head
  • fractures of the anterior glenoid lip
  • fractures of the greater tuberosity
  • fractures of the acromion or coracoid process

Fracture of humeral head is called Hill Sachs lesion. [Read more...]

Xray of Fracture of Fourth and Fifth Metacarpal

The image is antero-posterior view of xray wrist with hand. The present xray shows badly comminuted fracture of base of fifth metacarpal. Also seen is fracture of fourth metacarpal.

Author’s Note

The type of fracture indicates that there was a strong traumatic force that caused so much comminution. In such case of damage to articular cartilage, the functional results are often poor.

Xray of Posterior Dislocation of Elbow

Lateral View of Posterior Dislocation elbow

Lateral View of Posterior Dislocation elbow

The image shows a posterior dislcation of elbow. This is xray of a 60 nyears old woman who suffered household rauma but did not take any treatment for 4 weeks. There are some bone fragments visible too.

Note:

All dislocations are emergency. This elbow was neglected for 4 weeks and could not be reduced with closed methods. It was operated and funtional outcome is acceptable.

To avoid all kind of complications, all dislocations should be reduced immeditely. But the first step in that is to seek medical help.

Hemangioma of Synovial Membrane

Synovial hemangioma is a rare lesion. It is most probably a hamartoma or a congenital vascular malformation rather than a true neoplasm. The disease is most comonly noticed in  adolescents and young adults but th symptoms in most of the case can be traced back to childhood.

Knee is the most common affected site. Ankle, elbow, and shoulder may also be affected. [Read more...]

Pigmented Villonodular Synovitis

In this disease, the synovial membrane proliferates and its surface develops nodules and villi. It also turns into brown colour.

The cause of the condition is unknown. It is thought to be an inflammatory process. It occurs most commonly in young adult.

Two primary forms are described

  • Diffuse form that affects the entire synovial lining
  • Localized form.

The diffuse form is most common and  involves the large joints, while the localized form typically occurs around the small joints of the hands and feet. [Read more...]

Popliteal Cysts – Diagnosis and Treatment

Diagnosis of politeal cyst is usually evident on clinical examination. Conventional radiography in the anteroposterior, lateral, and oblique projections is done to check fluid density and to rule any other lesion that might give rise to poplliteal swelling.

Ultrasonography helps in assessing th swelling and  can distinguish between fluid and solid mass.Popliteal cysts are best shown by sagittal ultrasound image projection. Ultrsound can also be used o rule vascular tumours by looking at arterial pulsations. [Read more...]

Popliteal Cyst or Baker Cyst – Presentation

Popliteal cyst is a soft-tissue swelling in the posterior aspect of the knee which contains gelatinous fluid.It is also called Baker Cyst named after Dr. William Morrant Baker who first described it. Most common location is distal the popliteal crease under the medial head of the gastrocnemius muscle.

These conditions have also been referred in the past as gastrocnemio-semimembranosus bursae, semimembranosus burse, synovial cysts, posterior herniae of the knee joint.

The condition is unilateral mostly. It is almost twice as common in boys than the girls.

Pathological Findings

The cysts may be either bursal or hernial in origin.  The bursal cysts develops in bursa of the gastrocnemius-semimembranosus bursae. Hernial cysts protrude the capsule to lie outside.

The cysts are medially located mostly but  rarely they are laterally located and occasionally extend into the calf of the leg.

Infiltration by lymphocytes, plasma cells, histiocytes, and even polymorphonuclear cells may be seen in varying degrees. Areas of metaplasia into cartilaginous and osteoid elements may also be there.

Clinical Presentation

Symptoms

  • Presence of a swelling in the posterior aspect of the knee is the presenting complaint.
  • On occasion there may be stiffness and local pain.

Examination

  • A swelling is located distal to the popliteal crease
  • Swellingbecomes prominent when the knee is hyperextended and disappears on flexion
  • Consistency varies from soft to firm
  • Transillumination* test is positive

Synovial Chondromatosis

Synovial chondromatosis is a condition characterized by the formation of  multiple foci of cartilage in the  synovial membrane of a joint. It also occurs in bursae and tendon sheaths.

When the cartilage is ossified, the condition is called  synovial osteochondromatosis.

This is  a benign condition and is very rare in occurrence. It usually occurs in persons over 40 years of age and occasionally in adolescents. It is twice as common in the males [Read more...]

Treatment of Recurrent Subluxation or Dislocation of the Patella

The treatment of patellofemoral joint subluxation depends on the following factors.

  • Degree of lateral displacement of the patella
  • Mechanism or type of subluxation or dislocation-whether it is due to
    • Malalignment of the quadriceps mechanism with contracture of the lateral patellar retinaculum and iliotibial band.
    • Muscle imbalance between a weak and high oblique vastus medialis and a hypertrophied, low, and transverse vastus lateralis
    • Extreme ligamentous hyperlaxity
    • Trauma resulting  weakening of the vastus medialis.
    • Malposition of the patella
    • Angular or rotational deformity of the knee and leg
    • Presence or absence of bony hypoplasia of the lateral femoral condyle.
  • Presence or absence of chondromalacia of the patella.
  • Age
  • Psychological aspects

A rough guide to management of this condition is as follow [Read more...]
