Muscles that Move the Forearm01:16

Muscles that Move the Forearm

4.1K
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

Summary

Hyperpronation may be more effective than supination-flexion for treating pulled elbow (nursemaid's elbow) in young children. This method shows fewer treatment failures on the first attempt, though more research is needed.

Area of Science:

  • Pediatric Orthopedics
  • Musculoskeletal Trauma
  • Evidence-Based Medicine

Background:

  • Pulled elbow (nursemaid's elbow) is a common radial head subluxation in young children, typically caused by a sudden pull on the arm.
  • Treatment involves manual reduction, with supination-flexion and hyperpronation being common techniques, but their comparative effectiveness is unclear.

Purpose of the Study:

  • To compare the benefits and harms of different manipulative interventions for pulled elbow in young children.
  • To update a previous Cochrane review on this topic.

Main Methods:

  • Systematic review and meta-analysis of randomized or quasi-randomized controlled trials.
  • Included trials evaluated manipulative interventions for pulled elbow, with primary outcome being failure at the first attempt.
  • Searched multiple databases up to September 2016; nine trials involving 906 children were included.

Main Results:

  • Low-quality evidence suggests hyperpronation is more effective than supination-flexion, with significantly fewer failures at the first attempt (9.2% vs. 26.4%).
  • This translates to approximately 174 fewer failures per 1000 children treated with hyperpronation.
  • Evidence regarding pain and effectiveness of repeat manipulations is very low quality; adverse effects and recurrence were largely unreported.

Conclusions:

  • The pronation method appears more effective for initial pulled elbow reduction than supination-flexion, based on limited low-quality evidence.
  • High-quality randomized trials are needed to confirm these findings and definitively compare hyperpronation and supination-flexion.
  • Further research should address clinical equipoise and optimize study design for future trials.
