2D-3D reconstruction of distal forearm bone from actual X-ray images of the wrist using convolutional neural networks.

Sci Rep 2021 Jul 27;11(1):15249. Epub 2021 Jul 27.

Division of Information Science, Nara Institute of Science and Technology, 8916-5 Takayama, Ikoma, Nara, 630-0192, Japan.

The purpose of the study was to develop a deep learning network for estimating and constructing highly accurate 3D bone models directly from actual X-ray images and to verify its accuracy. The data used were 173 computed tomography (CT) images and 105 actual X-ray images of a healthy wrist joint. To compensate for the small size of the dataset, digitally reconstructed radiography (DRR) images generated from CT were used as training data instead of actual X-ray images. Read More

Thumb Carpometacarpal Instability.

J Am Acad Orthop Surg 2021 Jul 15. Epub 2021 Jul 15.

From the Attending Hand Surgeon, New York Hand & Wrist Center of Lenox Hill, New York, NY (Rabinovich, Beldner, and Polatsch), and the Attending Hand Surgeon, Cedars-Sinai Kerlan-Jobe Institute, Los Angeles, CA (Shin).

The basal joint complex of the thumb provides the framework necessary for function of the human hand. Although its unique saddle articulation allows for a wide range of motion necessary for routine function of the hand, it is rendered inherently unstable because of poor bony congruency and reliance on its capsuloligamentous support. Painful instability of this joint can stem from several causes including traumatic dislocation, various hypermobility conditions, and chronic overuse and microtrauma. Read More

Single incision thenar muscle reconstruction using the free functional pronator quadratus flap.

BMC Surg 2021 Jul 12;21(1):310. Epub 2021 Jul 12.

Department of Hand-, Plastic and Reconstructive Surgery, Burn Center, BG Trauma Center Ludwigshafen, Department of Hand- and Plastic Surgery, University of Heidelberg, Ludwig-Guttmann-Str. 13, 67071, Ludwigshafen, Germany.

Background: Injuries to the thenar muscle mass or the thenar branch of the median nerve and resulting loss of thumb opposition lead to a massive impairment of hand function. For decades, reconstructive approaches were based on tendon transfers.

Rev Bras Ortop (Sao Paulo) 2021 Jun 10;56(3):384-389. Epub 2021 Feb 10.

Disciplina de Cirurgia da Mão, Departamento de Ortopedia e Traumatologia, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brasil.

Distal radial fractures are very common. Vicious consolidation can occur in up to one third of these fractures, resulting in wrist pain, restricted movement, and, eventually, physical limitation or disability. The treatment of this condition consists in corrective osteotomy, which requires careful preoperative planning due to its three-dimensional complexity, especially in injuries with joint involvement.

Balance Between Mechanical Stability and Mechano-Biology of Fracture Healing Under Volar Locking Plate.

Ann Biomed Eng 2021 Jun 29. Epub 2021 Jun 29.

Department of Infrastructure Engineering, The University of Melbourne, Parkville, VIC, Australia.

The application of volar locking plate (VLP) is promising in the treatment of dorsally comminuted and displaced fracture. However, the optimal balance between the mechanical stability of VLP and the mechanobiology at the fracture site is still unclear. The purpose of this study is to develop numerical models in conjunction with experimental studies to identify the favourable mechanical microenvironment for indirect healing, by optimizing VLP configuration and post-operative loadings for different fracture geometries.

Scaphoid Nonunion Vascularized Bone Grafting in 2021: Is Avascular Necrosis the Sole Determinant?

J Hand Surg Am 2021 Jun 26. Epub 2021 Jun 26.

The Curtis National Hand Center, Baltimore, MD. Electronic address:

The decision regarding the use of vascularized bone grafting (VBG) or nonvascularized bone grafting for the treatment of scaphoid nonunion (SNU) needs guidelines based on patient- and fracture-specific risk factors. Historically, the presence of avascular necrosis was viewed as the primary indication for VBG; however, avascular necrosis is not the only indicator to determine whether VBG can improve our treatment of difficult SNU cases. The methods of detecting scaphoid avascular necrosis lack consensus and accuracy, limiting their use as decision-making tools. Read More

Giant Cell Tumor of the Distal Radius: Wide Resection, Ulna Translocation With Wrist Arthrodesis.

Cureus 2021 May 15;13(5):e15034. Epub 2021 May 15.

Orthopaedics, All India Institute of Medical Sciences (AIIMS) Raipur, Raipur, IND.

Giant cell tumor (GCT) of the bone is a locally aggressive neoplasm and usually managed with extended curettage and adjuvant therapy, which is associated with reduced risk of recurrence. The juxta-articular distal radius giant cell tumor is challenging due to the destruction of subchondral bone and articular cartilage, making it difficult to salvage the wrist joint anatomy and function. Various methods described include wide resection and reconstruction of allograft or centralization of the ulna with wrist arthrodesis. Read More

Surg Radiol Anat 2021 Jun 13. Epub 2021 Jun 13.

Department of Trauma and Orthopaedic Surgery, Royal London Hospital, Barts Health NHS Trust, London, UK.

A 25-year-old female presented with a chronic scapho-lunate ligament injury with development of carpal instability requiring reconstruction. During a standard dorsal longitudinal mid-line approach to the carpus, an extensor digitorum brevis manus (EDBM) muscle was found taking its origin from the dorsal wrist capsule overlying the lunate with innervation from the posterior interosseous nerve (PIN).

Point Blank: A Retrospective Review of Self-inflicted Gunshot Wounds to the Hand.

Hand (N Y) 2021 Jun 10:15589447211014603. Epub 2021 Jun 10.

University of Cincinnati College of Medicine, OH, USA.

Background: A paucity of literature exists specifically examining self-inflicted (SI) gunshot wounds (GSWs) to the hand and wrist, which impart greater energy and have a higher risk of adverse events than non-self-inflicted (NSI) GSWs.
