Table 2 Brief description of proximal humerus plates tested in the literature

From: Biomechanical analysis of plate systems for proximal humerus fractures: a systematic literature review

Plate name Manufacturer(s) Description
Proximal humerus internal locking system (PHILOS) plate Synthes (Paoli, PA, USA); Clinical House (Dusseldorf, NRW, Germany); Stratec (Birkenfeld, BW, Germany) Locking plate allowing insertion of mono-axial locking screws. Relatively low cross-section thickness
AxSOS plate Stryker (Kalamazoo, MI, USA) Locking plate allowing insertion of mono-axial locking screws
TIFIX plate LITOS (Ahrensburg, SH, Germany) Locking plate allowing insertion of mono-axial locking screws
PERI-LOC plate Smith and Nephew (Memphis, TN, USA) Locking plate allowing insertion of mono-axial locking screws
Humeral telescoping screw (HTS) plate M.O.R.E. Medical Solutions (Rostock, MV, Germany) Locking plate allowing insertion of mono-axial locking screws in addition to a telescoping screw
Non-contact bridging (NCB) plate Zimmer (Warsaw, IN, USA) Locking plate employing polyaxial screws, instead of the common monoaxial screws
DiPhos-H plate Lima Corporate (San Daniele del Friuli, UD, Italy) Locking plate manufactured from PEEK (poly-ether-ether-ketone), allowing insertion of mono-axial locking screws
PEEKPower plate Arthrex (Naples, FL, USA) Locking plate manufactured from PEEK allowing insertion of mono-axial locking screws
Spatial subchondral support (S3) plate Depuy (Warsaw, IN, USA) Locking plate allowing insertion of mono-axial locking screws. Placed more distally on the humeral head to reduce risk of subacromial impingement. Also allows insertion of smooth pegs and threaded pegs to avoid glenohumeral penetration of screws
Humerus block Synthes (Salzburg, Austria) Semi-rigid locking plate with four telescoping fixation pins where proximal end of each pin has a telescoping mechanism to its shortening under load. Pin tips also include three curved springs that are intended to improve pins’ fixation in cancellous bone and prevent their perforation into the glenohumeral joint
Button fix Synthes (Solothurn, SO, Switzerland) Semi-rigid PEEK plate with 4 threaded holes to allow insertion of 4 Kirschner wires using an aiming device
Semitubular blade plate Synthes (Paoli, PA, USA) Non-locking plate with a bend at its proximal end to form a blade
90° blade plate Zimmer (Warsaw, IN, USA) Non-locking plate with blade oriented at 90°
AO T plate Synthes (Paoli, PA, USA) Non-locking plate with a T-shaped profile
Cloverleaf plate Synthes (Paoli, PA, USA) Non-locking plate with a wide profile in contact with the humeral head
