Pronator Syndrome


Presentation

  • The average age of the patient at presentation was 41 years. Final follow-up averaged 22 months.[ncbi.nlm.nih.gov]
  • Full recovery is expected within one month after surgery if severe muscle atrophy is not present.[rocmd.com]
  • Presents over 350 illustrations—175 in full color and more than 100 new to this edition—as well as x-rays, CTs, and MRIs, helping you to confirm your diagnoses and confidently implement techniques.[books.google.com]
Disability

  • Practical, clinically relevant material facilitates the diagnosis and treatment of musculoskeletal, pain, and chronic disabling conditions.[books.google.com]
  • Pronator teres syndrome can cause compression of your median nerve, leading to pain and disability in your arm. Some careers require constant use of specific muscle groups, like the pronator teres in the forearm, which can lead to injury over time.[livestrong.com]
  • Hand function may be impaired but disability from this problem is rare. There are no tests to really confirm the diagnosis. Electrodiagnostic tests are typically used to confirm other nerve compression problems.[loptonline.com]
  • Upper extremity nerve entrapments are a common cause of pain and disability. The increase in repetitive motions associated with occupational and recreational environments usually is singled out as the primary cause of these problems.[massagetoday.com]
Arm Pain

  • The following are typical pronator teres syndrome symptoms: Tingling sensation in palm, forearm, and fingers Pain in palm, forearm, and fingers Stiff fingers or limited finger movement Muscle tenderness, especially when touched Forearm pain Weakness in[belmarrahealth.com]
Long Arm
  • Postoperatively, a long arm splint is placed. Eight to ten days later, the splint is removed, sutures are removed, and the patient is transitioned to a removable splint.[handandwristinstitute.com]
Musculoskeletal Pain
  • Practical, clinically relevant material facilitates the diagnosis and treatment of musculoskeletal, pain, and chronic disabling conditions.[books.google.com]
Disfiguring Scar
  • PURPOSE: Traditional surgical management for pronator syndrome results in a relatively long and possibly disfiguring scar across the antecubital fossa.[ncbi.nlm.nih.gov]
  • The traditional lazy S incision for pronator tunnel exploration has potential healing problems in the radial corner of the incision which may be dependent on flap thickness.3 To prevent a potentially disfiguring scar, a wavy incision has replaced the[healio.com]
Impulsivity
  • The electrochemical impulse will cause the thumb muscle to contract: You just moved your thumb. These nerve signals travel about 50 meters per second.[scarysymptoms.com]
  • But in the case of pronator syndrome, stimulating the nerve with an electrical impulse shows there’s a problem in nerve conduction for only one out of every 10 patients with symptoms of pronator syndrome.[loptonline.com]
Distractibility
  • A self-retaining retractor maybe helpful distracting the wound margins in the distal-proximal direction. The nerve is dissected with ease under direct vision as far as possible (Figure 6-7b). A subcutaneous tunnel is created distally and proximally.[flandershealth.us]
Poor Coordination
  • Symptoms and signs include aching in the wrist with a subjective feeling of poor coordination; paresthesias extending into the hand; paresis of the thumb muscles; pain on pronation of the forearm and flexion of the wrist against resistance; and tenderness[medical-dictionary.thefreedictionary.com]

Workup

Treatment

  • Proper localization is crucial to treatment options. Surgery can provide benefit in selected cases.[ncbi.nlm.nih.gov]
  • Treatment for Elbow Entrapment by the Pronator Teres Muscle Conservative treatment is the first treatment and often very successful. Treatment goals are to decrease muscle spasms and irritation around the elbow, pronator teres, and forearm muscles.[laserneuropathypaintreatment.com]
  • Knowing which is involved leads to a treatment plan.[handsport.us]
  • Treatment Options In the event that non-surgical treatment is ineffective, Dr.[loredohands.com]

Prognosis

  • Prognosis for Pronator Teres Syndrome Prognosis for prospective patients is usually favorable, with many post-operative patients reporting that they became pain-free or had a great reduction of their symptoms.[handsport.us]
  • Coverage of each disorder includes more details on treatment and prognosis.[books.google.com]
  • Prognosis: Following the protocol devised at Action Chiropractic & Sport Therapy, significant relief can be anticipated within two weeks. This is well ahead of the standard weeks to months that are often suggested.[southcalgarychiropractor.ca]
  • Treatment and prognosis Conservative treatment may be effective in 50–70% of cases with extremity rest and non-steroidal anti-inflammatory drugs. Corticosteroids have also been used.[radiopaedia.org]
  • […] mobilisation interventions for CTS. [ 13 ] There is only poor-quality evidence from very limited data to suggest that therapeutic ultrasound may be more effective than placebo for either short- or long-term symptom improvement in people with CTS. [ 14 ] Prognosis[patient.info]

Etiology

  • Fibrous bands from the pronator muscle, encircling the nerve, seemed to be an etiological factor. Eight of nine patients were either improved or recovered completely by surgical treatment.[ncbi.nlm.nih.gov]
