BACKGROUND Extensor pollicis longus (EPL) tendon rupture is a potential complication following distal radius fracture, typically occurring several weeks after injury. Herein, we present a rare case of acute extensor pollicis longus tendon rupture associated with a distal radius fracture. CASE REPORT A 35-year-old woman visited our hospital with a distal radius fracture.

Ultrasound Evaluation of Upper Limb Sublesional Muscle Morphology in Cervical Spinal Cord Injury.

Muscle Nerve

January 2025

International Collaboration on Repair Discoveries (ICORD), Vancouver, British Columbia, Canada.

Introduction/aims: Upper limb paralysis is arguably the most limiting consequence of cervical spinal cord injury (cSCI). There is limited knowledge regarding the early structural changes of muscles implicated in grasp/pinch function and upper extremity nerve transfer surgeries. We evaluated: (1) muscle size and echo intensity (EI) in subacute cSCI (2-6 months) and (2) the influence of lower motor neuron (LMN) damage on these ultrasound parameters.

Cases: Two patients with spontaneous loss of thumb interphalangeal joint extension were referred after history, electrodiagnostic, and/or magnetic resonance imaging (MRI) findings were felt to demonstrate a posterior interosseous nerve (PIN) palsy. Subsequent physical examination and additional directed studies suggested an alternative explanation: rupture of the extensor pollicis longus (EPL) tendon, subsequently confirmed at surgery. An extensor indicis proprius to EPL transfer restored thumb function.

Is Extensor Indicis Proprius Tendon Transfer an Innocent Surgical Procedure for the Restoration of Extensor Pollicis Longus Function?

Acta Chir Orthop Traumatol Cech

January 2025

University of Mersin, School of Medicine, Department of Orthopaedics and Traumatology, Division of Hand Surgery, Mersin, Turkey.

Purpose Of The Study: The aim of this study to evaluate the subjective and objective results of Extensor indicis proprius (EIP) to extensor pollicis longus (EPL) transfer with an emphasis on donor site morbidity.

Material And Methods: 17 patients (59% men, 41% women) who underwent EIP-EPL transfer were retrospectively analyzed. The mean age was 43 (9-64) years, and the mean follow-up was 72 (19-124) months.

Introduction: By combining nerve and tendon transfer procedures, a more versatile hand function can be expected. Here we report the long-term outcomes of novel, individualized reconstruction strategies using combined nerve and tendon transfer procedures (CNaTT) to restore prehension and grasp in two patients with tetraplegia.

Case Presentation: Two women, 45 years of age, underwent bilateral nerve transfer according to the Bertelli S-PIN (supinator to posterior interosseous nerve transfer) procedure.
