To determine whether stress fractures are associated with bone microstructural deterioration we quantified distal radial and the unfractured distal tibia using high resolution peripheral quantitative computed tomography in 26 cases with lower limb stress fractures (15 males, 11 females; mean age 37.1 ± 3.1 years) and 62 age-matched healthy controls (24 males, 38 females; mean age 35.0 ± 1.6 years). Relative to controls, in men, at the distal radius, cases had smaller cortical cross sectional area (CSA) (p = 0.012), higher porosity of the outer transitional zone (OTZ) (p = 0.006), inner transitional zone (ITZ) (p = 0.043) and the compact-appearing cortex (CC) (p = 0.023) while trabecular vBMD was lower (p = 0.002). At the distal tibia, cases also had a smaller cortical CSA (p = 0.008). Cortical porosity was not higher, but trabecular vBMD was lower (p = 0.001). Relative to controls, in women, cases had higher distal radial porosity of the OTZ (p = 0.028), ITZ (p = 0.030) not CC (p = 0.054). Trabecular vBMD was lower (p = 0.041). Distal tibial porosity was higher in the OTZ (p = 0.035), ITZ (p = 0.009), not CC. Stress fractures are associated with compromised cortical and trabecular microstructure.

Forty patients since 1988 have had distal tibial bone grafting for 41 arthrodeses of the foot and ankle. Bone graft is obtained through a cortical window made just above the medial metaphyseal distal tibial flare. Average follow-up was 23.3 months. Forty of 41 arthrodesis sites fused; there was only one nonunion. There were no delayed unions. There were no complications at the donor site based on patient examination and radiographs. Ipsilateral ankle motion was not affected by the bone graft procedure. Cited complications from iliac crest bone graft include donor site pain, blood loss, heterotopic bone formation, pelvic instability, iliac hernia, infection, fracture, and deformity. Complications with allografts include disease transmission and immune response. These are avoided by using locally obtained distal tibia autograft for arthrodeses in the foot and ankle.

Objectives The aim of this study was to describe the demography, aetiology, location and classification of physeal fractures in cats, and to describe their management and outcomes. Methods Clinical records and radiographs of cats referred for management of physeal fractures were retrospectively reviewed. Fractures of the proximal femoral physis were excluded. Descriptive statistics were used to describe signalment, cause of injury, presence of concurrent injuries, fracture description, treatment modality, complications, follow-up, physeal closure, implant removal and outcome. Results Thirty-four cats with 36 fractures were included, of which 17 affected the distal femur, 11 the distal tibia and fibula, five the distal radius and ulna, two the proximal tibia and one the distal humerus. Salter–Harris classification was type I in 14, type II in 16, type III in two and type IV in four fractures. Thirty-four fractures were treated with primary fixation, and the most common method was crossed Kirschner wires (24/34 fractures). Complications were observed in 14 fractures, of which 12 were minor. At radiographic follow-up, physeal closure was reported in 23 fractures, of which 15 were considered premature. Implant removal was performed in three fractures. Outcome was good in 28, fair in four and poor in two fractures. Conclusions and relevance Fracture of the distal femoral physis was the most common physeal fracture seen. Cats presenting with physeal fractures may be skeletally immature or mature with delayed physeal closure. The rate of physeal closure after fracture repair was relatively high but without apparent impact. The frequency of implant removal was very low, indicating that despite having a physeal fracture repair, most cats did not require a second procedure to remove implants. Overall, internal fixation provided a good outcome in most fractures.

Background: The purpose of this article is to document the normal arthroscopic appearance of the posterior ankle capsular and ligamentous structures, and variations in their anatomical relationships. Methods: 102 ankle arthroscopy videotapes were evaluated retrospectively for the configuration of the posterior capsuloligamentous structures. Based on these observations, the variations in the appearance and position of the posterior tibiofibular ligament (PTFL) and transverse (tibiofibular) ligament (TTFL) were documented. In addition, differences in the appearance of the flexor hallucis longus (FHL) were also noted. Results: All patients had evidence of both a PTFL and TTFL, which formed a labrum or meniscus-like addition to the posterior distal tibia. No patients demonstrated disruption of the PTFL; 3 had tears of the TTFL. We noted 4 distinct patterns of the PTFL and the TTFL. Thirty-four patients (33%) had a gap of ≥2 mm between the 2 ligamentous structures. Thirty-three (32.4%) had a gap <2 mm between the PTFL and TTFL. Twenty-six (25.5%) had a confluence of the 2 ligaments without a gap. Nine (9%) demonstrated a sizable gap between the 2 ligaments, and the TTFL appeared as a “cord-like” structure. Conclusion: To our knowledge, this is the first article to describe the variations in the arthroscopic normal posterior capsuloligamentous structures and FHL of the ankle. Level of Evidence: Level IV, case series.
