The ‘nutcracker’ spino-laminar fracture: evaluation as a sentinel lesion of a hyperextension mechanism in cervical spine trauma
ObjectiveWe hypothesised that the orientation of the fracture line in the cervical vertebral arch depends on the traumatic mechanism, specifically...

Cross-sectional study of the prevalence of hyperextension of the first metatarsophalangeal joint and its relationship to onycholysis in women with hallux valgus
BackgroundHallux Valgus (HV) deformity is associated with misalignment in the sagittal plane that affects the first toe. However, the repercussions...

Does higher knee hyperextension in patients with hemiplegia affect lateral and medial meniscus volume in the paretic leg? A cross-sectional study
BackgroundAfter stroke, an abnormal gait pattern gradually leads to knee pain and joint lesions, resulting the gait instability. However, the...

Rim plate in the treatment of hyperextension tibial plateau fracture: surgical technique and a series of cases
BackgroundThe existence of a “bare area” at the anterior plateau has been observed in cases where anteromedial and/or anterolateral proximal tibial...

Hyperextension following two different designs of fixed-bearing posterior-stabilized total knee arthroplasty
PurposeHyperextension after total knee arthroplasty (TKA) is related to worse functional outcomes. Among the reported predictive factors, it is...

Hyperextension-distraction fractures in ankylosing and spondylotic spines: injury profile and treatment results
Study designCase series study.
PurposeTo describe demographic metrics, and clinical and radiographical outcomes of surgical treatment in patients...

Is Surfer’s myelopathy an acute hyperextension-induced myelopathy? A systematic synthesis of case studies and proposed diagnostic criteria
BackgroundSurfer’s myelopathy is a rare complication of spinal hyperextension originally described in novice surfers. However, reports from patients...

The biomechanical effect of preexisting different types of disc herniation in cervical hyperextension injury
ObjectivePreexisting severe cervical spinal cord compression is a significant risk factor in cervical hyperextension injury, and the neurological...

Risk factors of de novo hyperextension developed after posterior cruciate ligament substituting total knee arthroplasty: a matched case–control study
PurposeTo investigate factors contributing to the de novo hyperextension after posterior cruciate ligament substituting (PS) total knee arthroplasty...
-
Comparison of risk for postoperative hyperextension between cruciate retaining and posterior stabilized total knee arthroplasties
IntroductionThe incidence of postoperative hyperextension and factors affecting hyperextension needs to be investigated separately for cruciate...

Complications associated with hyperextension bicondylar tibial plateau fractures: a retrospective study
BackgroundHyperextension bicondylar tibial plateau fracture (HBTPF) is a particular form of tibial plateau fracture which has gained increasing...

Does trapeziectomy with ligament reconstruction and tendon interposition arthroplasty correct the metacarpophalangeal joint hyperextension associated with trapeziometacarpal osteoarthritis?
IntroductionTrapeziometacarpal osteoarthritis sometimes results in hyperextension of the thumb metacarpophalangeal (MCP) joint, which could...

Female gender, decreased lateral center edge angle and a positive hyperextension–external rotation test are associated with ease of hip distractability at time of hip arthroscopy
PurposeTo identify factors associated with ease of hip distraction at the time of hip arthroscopy.
MethodsA retrospective review of patients...

Expanding the spectrum of congenital myopathies: prenatal onset with extreme hyperextension of the neck
We describe the case of a male newborn presenting with a prenatal diagnosis of persistent hyperextension of the fetal neck and severe hypotonia and...

A strategy to prevent complications of hyperextension type tibial plateau fracture
BackgroundTibial plateau fractures (TPFs) are the most common among periarticular fractures. Mechanism of injuries is most from varus/valgus and...

Clinical features and treatment of “Non-dislocated hyperextension tibial plateau fracture”
BackgroundTo explore the epidemiological characteristics, clinical characteristics, treatment strategies, and clinical results of non-dislocated...
