Closed rupture of flexor digitorum profundus in zone III.

BMJ Case Rep 2020 Apr 14;13(4). Epub 2020 Apr 14.

Orthpaedic Surgery, Tripler Army Medical Center, Honolulu, Hawaii, USA.

Closed ruptures of the flexor digitorum profundus (FDP) tendon cause a loss of active flexion at the distal interphalangeal joint. Commonly referred to as a 'jersey finger' because of its association with tackling sports, the distal aspect of FDP is avulsed from its insertion on the distal phalanx in zone I, with or without a fragment of bone. Because of this classic injury mechanism and pattern, providers may not seek advanced imaging beyond plain radiographs. Read More

Gouty Achilles Tendinopathy: A Case Report.

J Am Podiatr Med Assoc 2019 Jul;109(4):327-333

Tendinopathy in the presence of gouty arthropathy is relatively common, yet the clinical suspicion for gout involvement in acute tendon pain remains low. A 49-year-old man presented with an acute, tender, erythematous mass to the right posterior heel. A computed tomographic scan was obtained, which revealed a septated fluid collection superficial to the Achilles tendon. Read More

Outcomes of Reconstruction of the Flexible Adult-acquired Flatfoot Deformity.

Orthop Clin North Am 2020 Jan 17;51(1):109-120. Epub 2019 Oct 17.

Department of Orthopaedic Foot and Ankle Surgery, Hospital for Special Surgery, 535 East 70th Street, New York, NY 10021, USA. Electronic address:

Reconstruction of the flexible adult-acquired flatfoot deformity (AAFD) is controversial, and numerous procedures are frequently used in combination, including flexor digitorum longus transfer, medializing calcaneal osteotomy (MCO), heel cord lengthening/gastrocnemius recession, lateral column lengthening (LCL), Cotton osteotomy or first tarsometatarsal fusion, and spring ligament reconstruction. This article summarizes recent studies demonstrating that patients have significant improvements after operative treatment of flexible AAFD. It reviews current literature on clinical and radiographic outcomes of the MCO, LCL, and Cotton osteotomies. Read More

Osteoarticular radiographic findings of the distal forelimbs in Tbourida Horses.

Heliyon 2019 Sep 30;5(9):e02514. Epub 2019 Sep 30.

Hassan II Institute of Agronomy and Veterinary, Department of Medicine, Surgery, and Reproduction, Madinat Al Irfane, Rabat, BP 6202, Morocco.

Tbourida is a traditional Moroccan equestrian sport in which 15 horses gallop 200 m in a line while riders fire into the sky with muskets. The stop is the finale and representative demands of this equestrian event. Such particular sudden stop after a fast gallop requires a hyperextension of the metacarpophalangeal joint. Read More

Transforming Growth Factor Beta 3-Loaded Decellularized Equine Tendon Matrix for Orthopedic Tissue Engineering.

Int J Mol Sci 2019 Nov 3;20(21). Epub 2019 Nov 3.

Saxonian Incubator for Clinical Translation, University of Leipzig, D-04103 Leipzig, Germany.

Transforming growth factor beta 3 (TGFβ3) promotes tenogenic differentiation and may enhance tendon regeneration in vivo. This study aimed to apply TGFβ3 absorbed in decellularized equine superficial digital flexor tendon scaffolds, and to investigate the bioactivity of scaffold-associated TGFβ3 in an in vitro model. TGFβ3 could effectively be loaded onto tendon scaffolds so that at least 88% of the applied TGFβ3 were not detected in the rinsing fluid of the TGFβ3-loaded scaffolds. Read More

Exceptionally large, atypically located spindle cell lipoma.

BMJ Case Rep 2019 Oct 31;12(10). Epub 2019 Oct 31.

Department of Orthopaedic Surgery, University of South Florida, Tampa, Florida, USA.

Spindle cell lipomas are a rare subtype of lipoma typically occurring in the shawl region of middle-aged men with a characteristic histological appearance consisting of mature adipocytes, ropey collagen and spindle cells. Those of extraordinary size or atypical anatomic location require a proper immunohistological workup to rule out more ominous malignancy. The authors report the rare presentation of a 54-year-old man with a large mass of the left palm causing discomfort and paresthesia for 6 months. Read More

Anatomy of the palmar cutaneous branch of the median nerve: A review.

J Orthop 2019 Nov-Dec;16(6):576-579. Epub 2019 Jun 5.

The University of Toledo College of Medicine, Department of Orthopaedics, 3000 Arlington Ave, Toledo, OH, 43614, USA.

The palmar cutaneous branch of the median nerve (PCBm) supplies afferent innervation to the volar aspect of the hand. It consistently originates from the radial side of the median nerve, travels in relation to the tendons of the palmaris longus and flexor carpi radialis muscles, and courses superficially through fascial planes to reach the surface of the palm. Because it is at risk of injury in numerous operations, this review serves to provide a summary of anatomical findings regarding the PCBm across various studies to aid orthopedists and other clinicians in anticipating the location of the nerve during surgical procedures.

Proximal Plantar Intrinsic Tendinopathy: Anatomical and Biomechanical Considerations in Plantar Heel Pain.

J Am Podiatr Med Assoc 2019 Sep;109(5):412-415

Plantar heel pain is often managed through podiatric and physical therapy interventions. Numerous differential diagnoses may be implicated in patients presenting with plantar heel pain; however, symptoms are often attributed to plantar fasciitis. Abductor hallucis, flexor digitorum brevis, and quadratus plantae share proximal anatomic attachment sites and mechanical function with the plantar fascia. Read More
