Scaphoid proximal pole fractures remain a surgical challenge because of high propensity for nonunion, osteonecrosis, and ultimately carpal collapse. Options for management of nonsalvageable proximal pole fractures include non-vascularized bone grafts, vascularized pedicled bone grafts, free vascularized bone flaps, and rib cartilage grafts. The proximal pole of the hamate can also serve as a replacement arthroplasty in the setting of proximal pole scaphoid nonunions with collapse, bone loss, and/or osteonecrosis. Read More

Excision of Incomplete Hook of the Hamate Fractures.

Orthopedics 2019 Mar 1;42(2):e232-e235. Epub 2019 Feb 1.

Incomplete hook of the hamate fractures are difficult to diagnose and should be promptly removed to expedite return to sport. From January 2000 to November 2016, 143 excisions of the hook of the hamate were performed following fracture of the hamulus. Of these 143 excisions, 17 were performed because of a preoperative diagnosis of incomplete fracture. Read More

Computerized tomographic prediction of flexor tendon injuries complicating hamate hook fractures.

J Hand Surg Eur Vol 2019 May 23;44(4):367-371. Epub 2019 Jan 23.

1 Department of Hand Surgery, Nagoya University Graduate School of Medicine, Nagoya, Japan.

We reviewed computerized axial tomography of 28 patients with hamate hook fractures who had surgical resection of the hook. We analysed the relationship between the fragment height ratio, fragment gap, and intraoperative findings of the tendons. We determined whether parameters in the images can predict complication of tear or disruption of the flexor tendons to the ring or little fingers. Read More

Augmented External Fixation of Ulnar Carpometacarpal Joint Fracture Dislocations.

Tech Hand Up Extrem Surg 2019 Jun;23(2):84-87

Cleveland Clinic.

Ulnar-sided carpometacarpal (CMC) joint fracture dislocations are relatively uncommon, frequently associated with fractures of the metacarpal base and/or hamate, and often sustained by young male individuals secondary to striking a hard object. The complexity of ulnar-sided CMC fracture dislocations necessitates careful restitution of anatomic alignment and joint congruency for mobility and stability. Miniaturization of the external fixation device has allowed application to the hand. Read More

Dorsal buttress plate fixation for the treatment of fracture-dislocation of the fifth carpometacarpal joint with avulsion fracture of the hamate: a case report.

Arch Orthop Trauma Surg 2019 Jan 9;139(1):135-139. Epub 2018 Nov 9.

Department of Orthopaedic Surgery, Gifu University Graduate School of Medicine, Yanagido 1-1, Gifu, 501-1194, Japan.

Fracture-dislocations of the fourth and fifth carpometacarpal (CMC) joints present a complex situation. Misdiagnosis and inadequate treatment may cause malunion and residual subluxation, which lead to painful arthritis and grip weakness. Open reduction along with internal fixation is the treatment of choice, but there is no consensus on an optimal treatment approach. Read More

Return to Play After Hook of Hamate Excision in Baseball Players.

Orthop J Sports Med 2018 Oct 17;6(10):2325967118803090. Epub 2018 Oct 17.

Kerlan-Jobe Orthopaedic Clinic, Los Angeles, California, USA.

Background: Fractures of the hook of hamate in baseball players are significant injuries that can lead to pain and missed time from competition. The diagnosis is typically delayed because of the vagueness of symptoms and normal radiographic findings. Excision of the nonunited fragment has been supported as the primary treatment, but there are currently limited information and data on a timetable for return to competition after surgery. Read More

Variations in Hook of Hamate Morphology: A Cadaveric Analysis.

J Hand Surg Am 2019 Jul 2;44(7):611.e1-611.e5. Epub 2018 Oct 2.

University Hospitals Case Medical Center, Department of Orthopaedic Surgery, University Hospitals of Cleveland, Cleveland, OH; Yale Medicine Orthopaedics, New Haven, CT.

Purpose: The hook of the hamate is an anatomical structure that separates the ulnar border of the carpal tunnel from Guyon's canal and serves as a landmark for surgeons. The hook of the hamate is also subject to fracture from injury. We hypothesize that there are variations in the hook of the hamate in the general population. Read More

The Effect of Thumb Immobilization on Fractures of the Hook of the Hamate: A Cadaver Study.

Hand (N Y) 2020 May 18;15(3):365-370. Epub 2018 Aug 18.

Torrance Orthopaedic & Sports Medicine Group, CA, USA.

Fractures of the hook of the hamate are rare. Nonoperative management has historically been immobilization in a short arm cast (SAC) without thumb immobilization with a high reported incidence of nonunion. The high prevalence of nonunion following nonoperative treatment may be secondary to motion at the fracture site. Read More
