Isolated dislocation of the pisiform bone

Fracture Dislocation of the Pisiform Bone in 14-Year-Old Boy-A Case Report

We present the case of a 14-year-old patient who suffered fracture dislocation of the pisiform bone (PB) along with fractures of the scaphoid, proximal radius, and proximal phalanx of the thumb due to high-energy trauma directly to the extended wrist. This combination of fractures has not been previously reported in the literature. Currently, there is no consensus in the literature regarding the optimal treatment approach for such cases. In our management, initial attempts at closed and open reduction were unsuccessful, leading to the decision for primary pisiformectomy. Our report includes a follow-up of 3.5 years, demonstrating a very good outcome. Based on this case and a few similar published cases, primary pisiformectomy appears to be a viable and well-accepted option, particularly among young patients. Additionally, we conducted a review of radiographic criteria and management strategies for this specific injury and related conditions.

Atraumatic Isolated Dislocation of Pisiform With Ulnar Nerve Palsy

Isolated pisiform dislocation is an uncommon condition, with a limited number of cases reported in the literature. We present a unique case of a 15-year-old male who experienced an atraumatic isolated dislocation of the pisiform bone in his left wrist and presented with pain, deformity, and ulnar nerve palsy in his little and ring fingers. Radiographic investigations confirmed the diagnosis of isolated pisiform dislocation, and the patient successfully underwent an open reduction, stabilization of pisiform, and exploration of the ulnar nerve.

Luxação distal isolada do pisiforme: Relato de caso

Isolated pisiform dislocation is a rare lesion with few cases described in the literature. This type of lesion is typically observed in young males and can be easily overlooked at first assessment. Isolated proximal dislocation is more common due to the action of the flexor carpi ulnaris (FCU) muscle.

We present the case of a 19-year-old male patient with isolated distal pisiform dislocation after wrist trauma. He underwent open reduction and internal fixation with Kirschner wires with excellent functional outcomes.

Although there is no consensual therapeutic method, closed reduction is a first-line treatment for acute presentations. Pisiform open reduction or excision may be performed alternatively or after a failed closed reduction.

Isolated acute pisiform dislocation presenting atypically as wrist sprain in the emergency department

The pisiform is a sesamoid bone with in flexor carpi ulnaris tendon. Isolated dislocation of the pisiform bone is not common. It is usually missed and diagnosed as a soft tissue injury or a sprain of the wrist by the emergency physicians. We present an unusual and unique case of a young man involved in a rugby tackle and who himself presented to the emergency department with a painful wrist. The diagnosis of a dislocated pisiform was initially missed; however it was later successfully treated with an open reduction leading to a satisfactory outcome.Early diagnosis and reduction is imperative to avoid prolonged morbidity and loss of earnings. A high index of suspicion is needed in young patients with wrist trauma displaying ulnar sided wrist pain.

Traumatic Dislocation of the Pisiform Bone

Pisiform dislocation is a rare wrist injury. The limited literature available describes this pathology in the form of case reports. An immediate closed reduction and immobilization is indicated for acute injury while there is a debate in the management of cases with delayed diagnosis or failed closed reduction. In this case, a 32-year-old, right-handed man visited the emergency department with pain at the ulnar side of his left wrist after a fall. The initial management involved immobilization, and the patient was referred to the authors' specialized clinic 10 days later because of persistence of important ulnar wrist pain. The choice of treatment was pisiform excision without ligament reconstruction with excellent functional results.

Fracture dislocation of the pisiform bone in children: a case report and review of the literature

Simultaneous fracture and dislocation of the pisiform is a rare condition, and only two cases have been reported in children. We retrospectively collected and reviewed clinical and radiographic data of a child with a type II Salter-Harris fracture of the distal radius, associated with fracture dislocation of the pisiform. In addition, we performed a systematic review of the literature available to date.

Fractures of the hamate and pisiform bones

Osseous injuries to the ulnar aspect of the carpus are increasing in frequency because of greater participation in sporting activities. Hamate body fractures are subdivided into coronal, sagittal oblique, proximal pole, and medial tuberosity fractures. Successful treatment of coronal fractures requires identification and treatment of associated disruption or instability of the ulnar 2 carpometacarpal joints. Displaced hamate hook fractures are optimally treated with early excision to avoid sequelae such as flexor tendon and nerve injury, and to allow early return to activity. Undisplaced pisiform fractures are managed nonoperatively, whereas displaced fractures and nonunions are treated by simple excision.

Traumatic dislocation of the pisiform: a case report

Isolated pisiform dislocation is rare. We present one such case in a 20-year-old man occurring after a direct injury to the wrist. After an initial delay in diagnosis and unsuccessful closed reduction, he underwent resection of the pisiform. At 12-month follow-up, he had full range of movement of the wrist and no residual pain.

Dislocation of the pisiform bone after severe crush injury to the hand

The pisiform bone dislocated in a 56-year-old worker who had a crush injury of his wrist. Open reduction and reconstruction of the ligaments resulted in proximal subluxation of the pisiform bone and post-traumatic arthritic changes. Other authors recommend that excision of the pisiform is considered to be a more appropriate method of treatment.

[Traumatic dislocation of the pisiform bone: a case report and review of the literature]

Traumatic dislocation of the pisiform bone is uncommon. The authors report a case treated by primary excision with a good result. The literature is reviewed and treatment choices are discussed.

Osteochondral fracture of the triquetrum: a case report

A case of osteochondral fracture of the triquetrum associated with pisiform subluxation in a 21-year-old woman is described. The fracture was diagnosed by tomography and magnetic resonance imaging. We consider that the fracture resulted from shear force produced by the pisiform subluxation. Excision of the pisiform provided complete relief of pain and a good functional result.

A Dislocated Pisiform: Case Report

Dislocation of the pisiform bone is rare. The present paper describes the 12th reported case of an isolated dislocated pisiform bone and a successful treatment result from closed reduction and splinting.
