Outcomes of Lisfranc Injuries Treated with Joint-Preserving Fixation.

Background: Open reduction and internal fixation (ORIF) with transarticular screws to stabilize Lisfranc injuries may increase the risk of arthritis or affect outcomes. Joint-preserving fixation using staples, bridge plating, or Lisfranc screws avoids iatrogenic articular damage. This study analyzes functional outcomes and complications in Lisfranc-injury patients who underwent joint-preserving fixation.

Prevention and Management of the Failed Flatfoot.

The acquired adult flatfoot deformity is a challenging condition to manage and even more so in a revision setting. To "get it right" the first time, it is important to completely understand the deformity by performing a complete history, careful physical examination, and deliberate evaluation of radiographs. There are several techniques to achieve the complete correction of complex flatfoot deformities.

Outcome of Lesser Metatarsophalangeal Joint Interpositional Arthroplasty With Tendon Allograft.

Background: Lesser toe metatarsal head degeneration and collapse can cause significant pain and disability. In the setting of global metatarsal head collapse, there are limited operative options. The purpose of our study was to evaluate clinical and radiographic outcomes after lesser toe metatarsophalangeal (MTP) joint interpositional arthroplasty with a tendon allograft and to describe the operative technique.

Estimating Lengths of Semitendinosus and Gracilis Tendons by Magnetic Resonance Imaging.

Purpose: To determine whether preoperative magnetic resonance imaging (MRI) can help predict the tendon-only length of the semitendinosus (ST) and the gracilis (G).

Methods: The distance from the tibial insertion to the distal-most aspect of the musculotendinous junction (MTJ) of the ST and G was estimated on preoperative MRI scans of patients undergoing primary anterior cruciate ligament (ACL) reconstruction with single-bundle, quadruple-stranded hamstring autograft. This MRI tendon-only length, measured by a musculoskeletal radiologist blinded to surgical findings, was compared to the actual tendon-only length measured upon harvesting each tendon.

Stability of two versus three peripheral pegs of the glenoid component in modern total shoulder arthroplasty.

Purpose: In total shoulder arthroplasty (TSA), the optimum number of peripheral pegs required for stability in the glenoid component is unknown. This study compared the stability of two versus three peripheral pegs in cemented glenoid components possessing a central press-fit peg.

Methods: Six unmodified glenoid components with three peripheral pegs, a large, central press-fit peg and six modified glenoid components with one inferior peripheral peg sharply removed were cemented into bone substitute polyurethane blocks.

Relationship of Musculotendinous Junction Location to Harvested Semitendinosus and Gracilis Tendon Length.

Background: Harvested hamstring tendon length has received scant attention in published anterior cruciate ligament (ACL) reconstruction literature, yet length can limit the ability to increase graft diameter by folding the tendon over more than once. Indeed, some ultrashort tendons may be too short to yield a clinically useful graft after being folded over just once. Ultimately, the total length of a harvested hamstring tendon may depend on the length of the tendon distal to its musculotendinous (MT) junction.
