Three-dimensional-guided navigation percutaneous screw fixation of fragility fractures of the pelvis.
Three-dimensional (3D)-guided navigation percutaneous screw fixation of pelvi-acetabular fractures has been reported in patients with high-energy trauma. Its use in fragility fractures of the pelvis is expanding and its results are promising. ⋯ 3D-guided navigation percutaneous screw fixation is a safe, precise, and effective surgical technique for managing fragility fractures of the pelvis.

Comparative analysis of functional outcome of anatomical precontoured locking plate versus reconstruction plate in the management of displaced midshaft clavicular fractures.
For the fixation of displaced midshaft clavicular fractures, different plates are available, each with its specific pros and cons. The ideal plating choice remains subject to ongoing discussion. Reconstruction plates are cheap and easily bendable, but their strength and stability have been questioned. The anatomical precontoured locking plates provide better stability and strength compared with the reconstruction plate. ⋯ Surgical management of fresh middle third clavicle fractures with anatomical precontoured locking plate provided stable fixation, faster union, and better functional outcome compared with the reconstruction plating. Anatomical plate had the advantage of less soft tissue stripping, and there is less need for lag screw fixation of the plate for fracture stability as precontoured plate itself provides a rigid construct.

Observational StudyThe incidence of biphalangeal fifth toe: Comparison of normal population and patients with foot deformity.
Pedal biphalangism, which was also defined as symphalangism, is seen at a frequency that cannot be ignored; however, no study can be found in the literature evaluating biphalangism in normal population in comparison to those who have foot disorders. The aim of this study was to evaluate the incidence of the pedal fifth toe symphalangism in normal population and in patients with foot deformity including hallux valgus, pes planus, pes cavus, and pes equinovarus. We hypothesized that pedal fifth toe symphalangism may be a predisposing factor or an accompanying structural variation for foot deformity. ⋯ According to the results of this study, biphalangeal fifth toe is a common pedal anatomical variant seen approximately in one-third of the population who have either foot deformity or not. This information may be valuable for podiatrist undertaking the conservative or surgical treatment of fifth toe-related disorders.

Comparative StudyClinical and radiological outcomes of arthroscopic en bloc repair for delaminated rotator cuff tear versus non-delaminated tear.
The objective of the study is to determine clinical and radiological outcomes of arthroscopic repair for delaminated tears versus non-delaminated tears. ⋯ Arthroscopic en bloc repair for delaminated rotator cuff tear showed no significant difference in clinical or radiological outcome from that for non-delaminated rotator cuff tear. The extent of delamination did not affect outcome either. Levels of Evidence: Level III, Retrospective comparative study.

Relationship between the elbow joint valgus instability and forearm flexor muscle strength in high school pitchers with and without symptom.
Earlier reports describe forearm flexor muscles as active stabilizers of the elbow to valgus stress during throwing motion. Given high school pitchers' history of elbow symptoms, this study assesses its relation to elbow valgus joint instability and forearm flexor muscle strength. ⋯ FCU muscle strength might influence high school baseball pitching performance.
