Fracture Fixation and Implants

OBJECTIVES: To compare the complication rate between open reduction and internal fixation (ORIF) and external skeletal fixation (ESF) for feline diaphyseal tibial fractures.

METHODS: In a retrospective study spanning a 10 year period, 57 feline tibial fractures stabilized via ESF or ORIF were included for analysis and complication rates were compared between the two methods.

OBJECTIVES: To assess the impact of stabilization method on the complication rate after lateral humeral condylar fracture (LHCF) repair.

STUDY DESIGN: Retrospective multicenter clinical cohort study.

ANIMALS: Dogs (n = 151) with LHCF.

OBJECTIVES: To investigate whether administration of postoperative oral antimicrobial drugs has a beneficial effect on preventing surgical site infections (SSI) in clean orthopedic surgery involving stainless steel plating systems.

STUDY DESIGN: Randomized prospective clinical study.

ANIMALS: Dogs (n = 97).

OBJECTIVE:  To evaluate the influence of epidemiologic, surgical, and mechanical factors on the durations of bone consolidation and external fixation after distraction osteogenesis in dogs.

STUDY DESIGN: Retrospective cohort study.

OBJECTIVES: To (1) develop guidelines for the location of drill entry and exit points when inserting a transcondylar screw across the canine humerus; (2) compare the safe corridor for transcondylar screw insertion when drilling medial-to-lateral with drilling lateral-to-medial.

STUDY DESIGN: Anatomic study.

ANIMALS: Dogs (n = 43).

OBJECTIVE: To biomechanically compare different loop and crimp configurations used for extracapsular suture stabilization of the CCL-deficient stifle.

STUDY DESIGN: In vitro study.

SAMPLE POPULATION: Crimped loop constructs of 100 lb Ande type nylon leader line in 7 different configurations comprising single and double loops, single and double crimps, and the interlocking loop configuration.

OBJECTIVE: To 1) assess the bending strength and stiffness of canine cadaver spines after fixation of a lumbar spinal fracture-luxation using a novel unilateral stabilization technique with pins and polymethyl methacrylate (PMMA) and 2) compare the results to a reference standard dorsal pin and PMMA technique.

STUDY DESIGN: A randomized non-inferiority trial.

SAMPLE POPULATION: Cadaveric lumbar spines (L1-L6) from 20 Greyhounds.

OBJECTIVE: To assess the influence of locking plate and screw implants on postoperative infection rate in dogs >50 kg undergoing tibial plateau leveling osteotomy (TPLO).
STUDY DESIGN: Retrospective case series.
ANIMALS: Dogs >50 kg (n = 208) that had TPLO.

OBJECTIVE: To (1) investigate the use of K-wires as alignment aids for cranial closing wedgeostectomy (CCWO) and (2) evaluate their effect on osteotomy accuracy and angular/rotational alignment.
STUDY DESIGN: Cadaveric study.
ANIMALS: Cadaveric pelvic limbs (n = 20).

To describe and compare a large population of dogs that had pancarpal arthrodesis (PCA) using either a hybrid dynamic compression plate (HDCP) or a CastLess Plate (CLP).
