ABSTRACT

External fixation with a bilateral frame configuration (delta frame, DF) is a routine approach for treating ankle fractures and dislocations with severe soft tissue damage. The purpose of this study was to evaluate to what extent adding a first metatarsal fixation contributes to the stability of the fixation as evidenced by reduced frequency of early loss of reduction. A retrospective study was performed to compare the rate of early reduction loss in patients treated with a bilateral frame external fixation as part of a 2-stage treatment protocol for periarticular ankle fractures, in a level one trauma center between 2006 and 2016. The cohort was divided into 2 groups according to the frame configuration that had been used: DF only and DF with first metatarsal fixation (DF+1MT). A multivariate analysis assessing risk factors for postoperative loss of reduction was conducted. A total of 67 patients were included in the study, of which 30 underwent fixation by DF and 37 by DF+1MT. Early loss of reduction was recorded in 13 (19.4%) patients, 6 (20%) in the DF group and 7 (18.9%) in the DF+1MT group (p = .576). None of the assessed risk factors reached statistical significance. To conclude, the addition of a first metatarsal pin as an enhancement of external fixation with a delta frame configuration did not reduce the incidence of early loss of reduction. There is no evidence to support the claim that adding this pin contributes to the stability of the fixation in a clinically relevant manner.

ABSTRACT

BACKGROUND: Gait metric alterations have been previously reported in patients suffering from chronic ankle instability (CAI). Previous studies of gait in this population have been comprised of relatively small cohorts, and the findings of these studies are not uniform. The objective of the present study was to examine spatiotemporal gait metrics in patients with CAI and examine the relationship between self-reported disease severity and the magnitude of gait abnormalities. METHODS: Forty-four patients with CAI were identified and compared to 53 healthy controls. Patients were evaluated with spatiotemporal gait analysis via a computerized mat and with the Short Form (SF) - 36 health survey. RESULTS: Patients with CAI were found to walk with approximately 16% slower walking velocity, 9% lower cadence and approximately 7% lower step length. Furthermore, the base of support, during walking, in the CAI group was approximately 43% wider, and the single limb support phase was 3.5% shorter compared to the control group. All of the SF-36 8-subscales, as well as the SF-36 physical component summary and SF-36 mental component summary, were significantly lower in patients with CAI compared to the control group. Finally, significant correlations were found between most of the objective gait measures and the SF-36 mental component summary and SF-36 physical component summary. CONCLUSIONS: The results outline a gait profile for patients suffering from CAI. Significant differences were found in most spatiotemporal gait metrics. An important finding was a significantly wider base of support. It may be speculated that these gait alterations may reflect a strategy to deal with imbalance and pain. These findings suggest the usefulness of gait metrics, alongside with the use of self-evaluation questionnaires, in assessing disease severity of patients with CAI.

ABSTRACT

The calcaneus is the most frequently fractured tarsal bone. Compartment syndrome (CS) complicates fractures and other injuries and is most commonly described in association with the lower leg. The long-term sequelae of CS of the foot can include toe clawing, permanent loss of function, persistent pain, muscle atrophy, contracture, painful warts, weakness, and sensory disturbances. The incidence and clinical significance of untreated CS after calcaneal fractures were questioned. All compliant patients treated by us for a calcaneus fracture underwent a physical examination and medical interview: 47 (49 fractures) were included in the final cohort (36 males, 11 females, mean age 49 ± 14.5 years, mean follow-up 23 ± 16 months). Missed CS sequelae were diagnosed by the presence of claw toes and plantar sensory deficits. The functional outcome and pain at rest and during activity were scored. Five patients (10%) had missed CS, and their functional score was significantly lower than for those without CS (52 ± 21.5 versus 77.4 ± 22 for no CS, p < .05). All missed CS cases were diagnosed in patients with a Sanders type 3 or 4 fracture. Intra-articular fracture was a significant factor associated with developing CS sequelae (p = .045). Untreated CS can cause muscle and nerve injury and contribute to a poor functional outcome. Because CS is more likely to develop after highly comminuted intra-articular fractures, these patients warrant close monitoring for CS development. Early detection and treatment might result in fewer late disabling sequelae of this injury.

ABSTRACT

The authors retrospectively reviewed 27 consecutive patients with 29 fractures of the distal femur treated with the new retrograde expandable nail. One 10-mm diameter nail that expands to 16 mm was used with the possibility of locking in the condylar area only. Retrieved data included single versus multiple injuries, fracture type, operation time, reaming or nonreaming, hospitalization and healing times, and intra- and postoperative complications. The overall average operation time was 96 (range 40-320) minutes, but only 65 (range 40-120) minutes for isolated fractures. The overall mean hospitalization time was 16 (range 3-40) days, but only 7 (range 4-10) days for isolated fractures. Follow-up continued until fracture healing or for a minimum of 1 year (average 14 months, range 12-24 months). The average clinical union time was 83 (range 43-179) days, and the mean radiographic healing was 87 (range 43-179) days. One patient developed a nonunion that required exchange of the nail to the same device. Another patient underwent hardware removal during a procedure for a torn meniscus. These preliminary results demonstrate satisfactory healing and alignment for the treatment of distal femoral shaft fractures by means of this new device without jeopardizing the knee joint by nail protrusion.
