Purpose: To observe the effect of the forearm rotation function reconstruction with an external fixator in treating congenital radioulnar synostosis.
Methods: From July 2017 to July 2023, 6 patients (9 sides) with congenital radioulnar synostosis who underwent reconstruction of the forearm rotation with the external fixator were retrospectively analyzed. The extent of flexion and rotation, the Modified An and Morrey functional rating index, and the grade according to the classification system proposed by Failla et al. were compared before and after the operation.
Results: All patients were followed up for an average of 12.00 (8.00, 38.50) months. The average range of rotation, the Modified An and Morrey functional rating index increased from 0°, 64.56 ± 1.33 points to 85.00° ± 25.86°, 83.71 ± 5.50 points, respectively. The differences were statistically significant (t = 9.86, P < 0.01, t = 11.20, P < 0.01). There was no significant difference in forearm flexion before and after the operation (Z = 1.34, P = 0.18). According to the Failla classification system, 2 forearms were classified as poor preoperatively, 6 as fair and 1 as good. 2 forearms were assessed as excellent, 6 as good and 1 as fair during the last follow-up.
Conclusion: Reconstruction of the forearm rotation function with an external fixator is safe and effective for treating congenital radioulnar synostosis. This technique can restore the partial rotational function of the forearm.

Background: Radial bowing is necessary for forearm rotation. Fractures or deformities of the forearm that affect the radial bow may disrupt normal forearm rotation.
Objective: The purpose of this study was to evaluate the development and establish normative values for the pediatric and adolescent radial bow.

Objective: To investigate the effectivess of arthroscopic Wafer surgery combined with triangular fibrocartilage complex (TFCC) insertion point reconstruction in the treatment of Palmer type ⅡC combined with typeⅠB ulnar impingement syndrome.
Methods: The clinical data of 14 patients with Parlmer type ⅡC combined with type ⅠB ulnar impingement syndrome who met the selection criteria between July 2021 and April 2024 were retrospectively analyzed. There were 7 males and 7 females with an average age of 43 years ranging from 16 to 59 years.

The purpose of this study was the detection and characterization of synergistic muscle activity. Using T-map MRI, T values for 10 forearm muscles in 11 healthy adult volunteers were obtained in the resting state and after isotonic forearm supination and pronation exercises with the elbow extended. T was normalized by Z = (T-T)/SD, where T was T after exercise, while T and SD were the reference values of 34 ms and 3 ms, respectively.

The forearm muscles coordinately control wrist motion, and their activity is affected by forearm rotation. Although forearm rotation has been implicated in the development of lateral and medial epicondylitis, its biomechanical background remains unknown. Therefore, the present study investigated the activity of wrist muscles in various forearm positions.

Article Synopsis
- Fractures of the proximal ulna and radial head often arise from falls or direct impacts, affecting elbow stability and function with symptoms like pain and limited motion.
- The common clinical scenario involves radial head dislocation accompanied by a proximal ulna fracture, known as a Monteggia fracture-dislocation.
- This study examines the surgical treatment of a patient with these fractures and their subsequent physical therapy follow-up.
