Aims and Scope

The Open Orthopaedics Journal is an Open Access online journal, which publishes high quality research articles, reviews/mini-reviews, letters and guest edited single topic issues in all important areas of experimental and clinical research and surgery in orthopaedics. The journal encourages submissions related to the following fields:

  • Paediatric Orthopaedics, and Orthopaedic Rehabilitation
  • Arthroscopy
  • Spine and Spinal Deformities
  • Joint Replacement
  • Traumatologic Surgery
  • Sports Medicine
  • Hand Microsurgery
  • Foot and Ankle Surgery
  • Musculoskeletal Tumour Management

The Open Orthopaedics Journal, a peer-reviewed journal, is an important and reliable source of current information on important recent developments in the field. The emphasis will be on publishing quality papers rapidly and making them freely available to researchers worldwide.

Robert Wartenberg Syndrome and Sign: A Review Article

Stuart H. Kuschner, Haben Berihun


Robert Wartenberg, a European-American neurologist, was born in 1887 and died in 1956. His description of radial sensory nerve compression at the forearm is memorialized as Wartenberg’s syndrome. He recognized that involuntary abduction of the little finger could be caused by ulnar nerve palsy - a finding often called Wartenberg’s sign Syndrome and signs are reviewed, and a brief biography is presented.


To review Wartenberg’s sign and Wartenberg’s syndrome.


Compression of the superficial branch of the radial nerve, often called Wartenberg’s syndrome, is characterized by pain, paresthesia, and dysesthesia along the dorsoradial distal forearm. Non-operative treatment can include activity restriction and anti-inflammatory medication. If symptoms persist, surgical decompression of the radial nerve is an option. The abducted posture of the little finger - Wartenberg’s sign - can result from a low ulnar nerve palsy. Tendon transfer can be performed to correct this deformity.


Compression of the superficial branch of the radial nerve and abducted posture of the little finger were described by Robert Wartenberg and carry his name as eponymous syndrome and sign, respectively.

Contrast-enhanced Magnetic Resonance Imaging Revealing the Joint Capsule Pathology of a Refractory Frozen Shoulder

Frozen shoulder (FS) is clinically diagnosed on the basis of patients’ medical history and physical examination. Its confirmation is based on joint capsule and coracohumeral ligament thickening, subcoracoid fat obliteration, and joint capsule contrast enhancement on magnetic resonance imaging (MRI). We performed bilateral contrast-enhanced MRI (CE-MRI) in FS patients to compare the outcomes with those of their unaffected contralateral counterparts.


Ten patients (3 men, 7 women, median age: 54.5 years) with unilateral FS, requiring arthroscopic capsular release after failed conservative treatment, were included. The median forward elevation, abduction, external rotation, and internal rotation of the 10 patients were 100°, 60°, 7.5°, and the buttock, respectively. The median visual analog scale score was 5.3, and American Shoulder and Elbow Surgeons (ASES) score was 42. Bilateral CE-MRI was simultaneously performed on the day before surgery, and MRI findings were compared between FS and contralateral healthy shoulders (controls).


Significant axillary pouch enhancement and rotator interval were observed in all FS, but not in the unaffected comparable sides (p=0.002, respectively). The thickness of the axillary pouch (FS: 4.8 mm, C: 4.4 mm, p=0.58), coracohumeral ligament (FS: 3.9 mm, C: 4.1 mm, p=0.33), and subcoracoid fat obliteration (p=1.00) were not significantly different between FS and controls.


CE-MRI aids in the clinical diagnosis of FS. However, axillary pouch joint capsule and coracohumeral ligament thickening or subcoracoid fat obliteration differences were not characteristic findings when contralateral shoulders were compared.
