Ipsilateral intact fibula as a predictor of tibial plafond fracture pattern and severity.

BACKGROUND: The objective of this study was to determine whether there is a difference in fracture pattern and severity of comminution between tibial plafond fractures with and without associated fibular fractures using computed tomography (CT). We hypothesized that the presence of an intact fibula was predictive of increased tibial plafond fracture severity. METHODS: This was a case control, radiographic review performed at a single level I university trauma center. Between November 2007 and July 2011, 104 patients with 107 operatively treated tibial pilon fractures and preoperative CT scans were identified: 70 patients with 71 tibial plafond fractures had associated fibular fractures, and 34 patients with 36 tibial plafond fractures had intact fibulas. Four criteria were compared between the 2 groups: AO/OTA classification of distal tibia fractures, Topliss coronal and sagittal fracture pattern classification, plafond region of greatest comminution, and degree of proximal extension of fracture line. RESULTS: The intact fibula group had greater percentages of AO/OTA classification B2 type (5.5 vs 0, P = .046) and B3 type (52.8 vs 28.2, P = .013). Conversely, the percentage of AO/OTA classification C3 type was greater in the fractured fibula group (53.5 vs 30.6, P = .025). Evaluation using the Topliss sagittal and coronal classifications revealed no difference between the 2 groups (P = .226). Central and lateral regions of the plafond were the most common areas of comminution in fractured fibula pilons (32% and 31%, respectively). The lateral region of the plafond was the most common area of comminution in intact fibula pilon fractures (42%). There was no statistically significant difference (P = .71) in degree of proximal extension of fracture line between the 2 groups. CONCLUSIONS: Tibial plafond fractures with intact fibulas were more commonly associated with AO/OTA classification B-type patterns, whereas those with fractured fibulas were more commonly associated with C-type patterns. An intact fibula may be predictive of less comminution of the plafond. The lateral and central regions of the plafond were the most common areas of comminution in tibial plafond fractures, regardless of fibular status. LEVEL OF EVIDENCE: Level III, case control study.

Late Effects of Clubfoot Deformity in Adolescent and Young Adult Patients Whose Initial Treatment Was an Extensive Soft-tissue Release: Topic Review and Clinical Case Series.

Children with congenital clubfoot often have residual deformity, pain, and limited function in adolescence and young adulthood. These patients represent a heterogeneous group that often requires an individualized management strategy. This article reviews the available literature on this topic while proposing a descriptive classification system based on a review of patients at our institution who underwent surgery for problems related to previous clubfoot deformity during the period between January 1999 and January 2012. Seventy-two patients (93 feet) underwent surgical treatment for the late effects of clubfoot deformity at an average age of 13 years (range 9 to 19 years). All patients had been treated at a young age with serial casting, and most had at least one previous surgery on the affected foot or feet. Five common patterns of pathology identified were as follows: undercorrection, overcorrection, dorsal bunion, anterior ankle impingement, and lateral hindfoot impingement. Management pathways for each group of the presenting problems is described. To our knowledge, this topic review represents the largest report of adolescent and young adult patients with residual clubfoot deformity in the literature.

First Metatarsophalangeal Joint Arthrodesis Technique With Interposition Allograft Bone Block.

BACKGROUND: We present a technique of first metatarsophalangeal joint arthrodesis utilizing an interposition allograft bone block with a bipolar reaming technique that creates congruent fusion surfaces on both ends of the graft-host bone interface. In addition, we examined the union rates, fusion position, patient satisfaction, and functional outcome of this technique. METHODS: Fifteen patients underwent first metatarsophalangeal joint arthrodesis with an interposition allograft bone block between September 2004 and October 2013. Charts and radiographs were reviewed. Six measures were compared on preoperative and postoperative radiographs. Clinical outcomes were measured using a telephone questionnaire, pre- and postoperative visual analog scale pain scale, and Foot and Ankle Ability Measure. Average follow-up was 46 weeks (range, 19 to 97). RESULTS: Thirteen of 15 (87%) patients achieved bony union at an average of 21 weeks. One patient underwent revision arthrodesis for their nonunion. Symptomatic hardware was removed in 3 cases. Improvement was noted in visual analog scale pain scores (6 to 2) and functional scores as measured by the Foot and Ankle Ability Measure. There were no postoperative wound complications or infections. Average length of the first ray on anteroposterior radiograph increased from 10.7 to 11.3 cm and from 10.0 to 10.7 cm on the lateral radiograph. Thirteen of 14 patients were very satisfied or satisfied. One patient expressed dissatisfaction with the procedure. One patient was not available for clinical follow-up. CONCLUSION: First metatarsophalangeal joint allograft bone block arthrodesis using the bipolar reaming technique achieved high bony union rates and satisfactory radiographic and clinical outcomes. This procedure was an effective salvage option for managing bone loss on 1 or both sides of the joint. LEVEL OF EVIDENCE: Level IV, retrospective case series.
