Comparison of TPLO tibial tuberosity fractures with and without an in situ rotational pin

Abstract

ObjectiveCranial cruciate ligament (CCL) rupture is a common cause of pelvic limb lameness in dogs. The tibial plateau leveling osteotomy (TPLO) is a well-described surgical procedure that treats CCL ruptures. The objective of this study was to compare the risk of tibial tuberosity fractures from TPLO procedures using a TPLO reduction pin in situ versus patients with a TPLO reduction pin removed at the time of surgery. Our hypothesis is that patients with a TPLO reduction pin left in situ will have a decreased incidence of tibial tuberosity fractures.ResultsA total of 400 dogs that fitted the criteria of 200 consecutive TPLO surgeries performed with each group were included in the study. The Student’s t-test revealed a statistically significant difference in fractures observed in group 1 (in situ pin) and group 2 (no pin). In univariate logistic regression analysis, only the covariate for the presence of the reduction pin was associated with a statistically significant reduction in the likelihood of tibial tuberosity fracture. In the multivariate model, the presence of the reduction pin was associated with an approximate 92% reduction in the likelihood of tibial tuberosity fracture.Electronic supplementary materialThe online version of this article (10.1186/s13104-018-3474-7) contains supplementary material, which is available to authorized users.

Surgical treatment of cranial cruciate ligament disease in dogs using Tibial Plateau Leveling Osteotomy or Tibial Tuberosity Advancement–A systematic review with a meta-analytic approach

“…Complications were recorded in the majority of the studies (58 studies in total, 36 TPLO, 17 TTA and five studies comparing TPLO and TTA). Not all of these studies have been considered into the systematic analysis due to a lack of complete data ( 43 , 79 ) or recorded data which only included certain types of complications ( 52 , 56 , 76 , 83 , 84 , 86 , 88 , 89 , 94 ). Some studies could not be matched to Group S, M or L as they did not provide information on mean body weight ( 35 , 97 ).…”

Prevalence, Risk Factors and Outcome of Postoperative Tibial Tuberosity Fractures in Dogs Undergoing Triple Tibial Osteotomy Surgery

“…Similar conservative treatment was described by Moles and colleagues in three patients that developed postoperative tibial tuberosity fracture following triple tibial osteotomy surgery. 3 Postoperative tibial tuberosity fracture has also been described in tibia plateau levelling osteotomy 11,12 and in some tibia tuberosity advancement 13,14 procedures, conservative management was normally associated with a good outcome; however, the authors recommend that severe lameness at presentation or a major displacement of the tibia tuberosity may warrant a surgical intervention. 8,[11][12][13][14][15][16][17][18] Although none of our cases needed revision surgery, there is always the risk that the tibial tuberosity fracture due to its displacement with its consequences and the possibility of needing revision surgery could lead to an unfavourable outcome.…”

Ulnar fracture after pancarpal arthrodesis: a case report

“…During plate application, stress risers are created in areas where there is a transition from an area with a relatively high moment of inertia to an area with a lower moment of inertia 1,5 . Therefore, fractures in the vicinity of a bone plate are a well-known complication in veterinary orthopedics 4,[6][7][8] . Fractures of adjacent bones after bone plating have been reported, for example, in the bula after tibia plateau leveling osteotomy and in the metacarpus IV after PCA 4,9 .…”
