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

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

Objective: The aim of this study was to evaluate the outcomes of open reduction and internal fixation (ORIF) in hamate hook fractures and review the literature on this surgical procedure.

Methods: We report the outcomes of ORIF of hamate hook fractures in 13 consecutive patients (12 men and 1 woman; mean age: 32 years (range, 22-48 years)). In eight patients (61%) the fracture was associated with ulnar nerve neuritis in Guyon's canal. Read More

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

Background: Within hand trauma, the management of unstable, intra-articular fractures of the base of the middle phalanx remains highly controversial. The objective of this research was to determine which operation gives the best outcome in the management of displaced, intra-articular fractures of the base of the middle phalanx causing instability of the proximal interphalangeal joint.

Methods: A scoping study was performed to determine the evidence available and the terminology used. Read More

Purpose: The purpose of this study was to determine the relationship between hemihamate graft size and proximal interphalangeal (PIP) joint flexion in a biomechanical fracture-dislocation model.

Methods: We simulated middle finger PIP fracture-dislocations in 5 cadaver hands by resecting 50% of the palmar articular surface of the middle phalanx (P2) base. Fluoroscopy was used to confirm dorsal subluxation of the middle phalanx base after resection. Read More

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

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

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

Background: 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

Purpose: Hemi-hamate arthroplasty has been described as a viable treatment option for unstable proximal interphalangeal joint fracture-dislocations. The procedure uses a dorsal distal hamate osteochondral graft to recreate the injured volar middle phalanx (MP) proximal base.

The hemi-hamate arthroplasty for proximal interphalangeal joint (PIPJ) dorsal fracture dislocations relies on complete dislocation of the joint using the 'shotgun' approach which provides excellent exposure but damages the delicate intrinsic joint stabilisers. We present a new approach to the PIPJ when performing the hemi-hamate arthroplasty. The volar surgical approach involves freeing up the whole tendon sheath-periosteal unit as a single layer, and retracting this to one side. Read More

Fracture dislocations of the proximal interphalangeal (PIP) joint of the finger are often caused by axial load applied to a flexed joint. The most common injury pattern is a dorsal fracture dislocation with a volar lip fracture of the middle phalanx. Damage to the soft-tissue stabilizers of the PIP joint contributes to the deformity seen with these fracture patterns. Read More

Objective: The scaphoid is the most commonly fractured carpal bone. The presence of a concomitant hook of hamate fracture is of particular relevance given that it is often occult on routine wrist/scaphoid radiographs and that hook of hamate fractures are prone to symptomatic non-union, resulting in chronic ulnar wrist pain. Prompt diagnosis and immobilisation/fixation may minimise such complications. Read More

Background: It is possible that some hamate hook fractures are not diagnosed or treated, thereby affecting the study of their natural history. Study of the prevalence of incidental hamate hook fractures, nonunions, and other abnormalities on computed tomography (CT) ordered for another reason could document a subset of undiagnosed and untreated hamate hook fractures which might change our understanding about the natural history.

Methods: Reports of 2489 hand, wrist, and forearm CT scans for hamate hook abnormalities were searched. Read More

A thorough understanding of the swing phases and mechanisms of injury in golf allows accurate diagnosis, treatment, and future prevention of injuries. Recommended initial treatment starts with cessation of practice to rest the wrist, a splint or orthotic brace, and nonsteroidal antiinflammatory drug medication with corticosteroid injection and swing modification. Pisiform excision is the best treatment of the most severe chronic cases of pisiform ligament complex syndrome. Read More

Objective: Hamate hook fractures are rare injuries, comprising 2% to 4% of all carpal fractures. Climbing athletes seem to be affected more frequently than others, as they strain the passive and active anatomical structures of their hands and fingers to maximum capacity during training or competing. This stress is transmitted to the hook of the hamate by tightened flexor tendons, which creates high contact pressure to the ulnar margin of the carpal tunnel. Read More

The wrist is a region that is very vulnerable to injuries of the extremities. Among these injuries, fractures of the pyramidal bone (or triquetrum) in association with dislocation of the hamate and carpal instability are uncommon. They are generally correlated with high-energy trauma and may be associated with neurovascular deficits, muscle-tendon disorders, skin lesions or injuries to other carpal bones. Read More
