POSTERIOR CAPSULAR CONTRACTURE AS THE CAUSE OF ADHESIVE CAPSULITIS

-
Special cases of only posterior capsular contracture revealed in the throwing athletes: In the throwing athlete, repetitive forces on the posteroinferior capsule may cause posteroinferior capsular hypertrophy and limited internal rotation. This may be the initial pathologic event in the so-called dead arm syndrome, leading to a superior labrum anteroposterior lesion and, possibly, rotator cuff tear.
In adhesive capsulitis posterior capsule is said to be more affected but in my opinion the entire capsule is affected and the arthrokinematic evaluation of joint plays must decide which is the part more affected. An article on Posterior capsular contracture was published in journal of American academy of orthopaedic surgeons. The points to remember about posterior capsular contracture are as follows:


1. Posterior capsular contracture is a common cause of shoulder pain in which the patient presents with restricted internal rotation and reproduction of pain.

2. Increased anterosuperior translation of the humeral head occurs with forward flexion and can mimic the pain reported with impingement syndrome; however, the patient with impingement syndrome presents with normal range of motion.
Management principles for only posterior capsule contractures: Initial management of posterior capsular contracture should be nonsurgical, emphasizing range-of-motion stretching with the goal of restoring normal motion. Management involves regaining internal rotation such that the loss of internal rotation is not greater than the increase in external rotation.
If reading the above said article still you think that it is only posterior capsule is contracted in frozen shoulder then you have to answer me following:
Why the inflammation is non-homogeneously located to posterior capsule?
Why the inflammation does not spread to other parts of the capsule?

Entrapment of medial calcaneal nerve (MCN)

Peripheral nerve entrapment is a rare, but important, cause of foot and ankle pain that often is underdiagnosed and mistreated. A peripheral nerve may become entrapped anywhere along its course, but certain anatomic locations are characteristic (2). The medial calcaneal nerve (MCN) The Tibial nerve is called the planter nerve in the sole. The tibial nerve passes to the sole of the foot takes a turn on the medial side of the calcaneum is called MCN. The medial calcaneal nerve arises from tibial nerve of the inner side of the ankle, perforates the laciniate ligament, travels downwards passing below the bony projection on the inner side of the ankle, and supplies the skin over the medial aspect of the heel. Hence it is the most important nerve for heel sensations. MCN have 2 branches. The anterior branch dominate the cutaneous sensation of the anterior part of the medial calcaneal and heel weight loading field, while the posterior branch dominate the sensation of the posterior an...

Differential diagnosis of Anatomic (Radial) snuffbox pain: It is not always DeQuervain’s tenosynovitis.

Tendon, Bone & Ligament causes: 1. DeQuervain’s tenosynovitis: Swelling of tendon of APL (Abductor pollicis longus) & extensor pollicis brevis at lateral wrist near anatomic snuff box.  The primary complaint is radial sided wrist pain that radiates up the forearm with grasping or extension of the thumb. The pain has been described as a “constant aching, burning, pulling sensation." Pain is often aggravated by repetitive lifting, gripping, or twisting motions of the hand. Swelling in the anatomical snuff box, tenderness at the radial styloid process, decreased CMC abduction ROM of the 1st digit, palpable thickening of the extensor sheaths of the 1st dorsal compartment and crepitus of the tendons moving from the extensor sheath may be found upon examination. Other possible findings include weakness and paresthesia in the hand. Finkelstein’s diagnostic test will present positive provoking the patient’s symptoms. If left untreated, the inflammation and progressive narro...

Chronic fatigue syndrome

-
Introduction: Severe fatigue is a common complaint among patients. Often, the fatigue is transient or can be attributed to a definable organic illness. Some patients present with persistent and disabling fatigue, but show no abnormalities on physical examination or screening laboratory tests. In these cases, the diagnosis of chronic fatigue syndrome (CFS) should be considered. According to Centers for Disease Control and Prevention (CDC, USA) Chronic fatigue syndrome (CFS) currently is defined as: (1) fatigue of at least 6 months' duration, seriously interfering with the patient's life; and (2) without evidence of various organic or psychiatric illnesses that can produce chronic fatigue. The World Health Organization classifies myalgic encephalomyelitis/chronic fatigue syndrome (ME/cfs) as a nervous system disease. Together with other diseases under the G93 heading, ME/cfs shares a triad of abnormalities involving elevated oxidative and nitrosative stress (O&NS), activat...
