Ankle motion and muscle extensibility during supine kicking in infants born fullterm and infants born preterm

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.

Background: Foot–ankle motion is affected by chronic ankle instability (CAI) in terms of altered kinematics. This study focuses on multisegmental foot–ankle motion and joint coupling in barefoot and taped CAI patients during the three subphases of stance at running. Methods: Foot segmental motion data of 12 controls and 15 CAI participants during running with a heel strike pattern were collected through gait analysis. CAI participants performed running trials in three conditions: barefoot running, and running with high-dye and low-dye taping. Dependent variables were the range of motion (RoM) occurring at the different inter-segment angles as well as the cross-correlation coefficients between predetermined segments. Results: There were no significant RoM differences for barefoot running between CAI patients and controls. In taped conditions, the first two subphases only showed RoM changes at the midfoot without apparent RoM reduction compared to the barefoot CAI condition. In the last subphase there was limited RoM reduction at the mid- and rearfoot. Cross-correlation coefficients highlighted a tendency towards weaker joint coupling in the barefoot CAI condition compared to the controls. Joint coupling within the taped CAI conditions did not show optimization compared to the barefoot CAI condition. Conclusions: RoM was not significantly changed for barefoot running between CAI patients and controls. In taped conditions, there was no distinct tendency towards lower mean RoM values due to the mechanical restraints of taping. Joint coupling in CAI patients was not optimized by taping.

Sensory Organization

The Sensory Organization Test protocol of the EquiTest system (NeuroCom International, Clackamas Oregon) tests utilization of visual, vestibular, and proprioceptive sensors by manipulating the accuracy of visual and/or somatosensory inputs during quiet stance. In the standard Sensory Organization Test, both manipulation of sensory input (sway-referencing) and assessment of postural sway are based on ground reaction forces measured from a forceplate. The purpose of our investigation was to examine the use of kinematic measurements to provide a more direct feedback signal for sway-referencing and for assessment of sway. We compared three methods of sway-referencing: the standard EquiTest method based on ground reaction torque, kinematic feedback based on servo-controlling to shank motion, and a more complex kinematic feedback based on servo-controlling to follow position of the center of mass (COM) as calculated from a two-link biomechanical model. Fifty-one normal subjects (ages 20–79) performed the randomized protocol. When using either shank or COM angle for sway-referencing feedback as compared to the standard EquiTest protocol, the Equilibrium Quotient and Strategy Score assessments were decreased for all age groups in the platform sway-referenced conditions (SOT 4, 5, 6). For all groups of subjects, there were significant differences in one or more of the kinematic sway measures of shank, hip, or COM angle when using either of the alternative sway-referencing parameters as compared to the standard EquiTest protocol. The increased sensitivities arising from use of kinematics had the effect of amplifying differences with age. For sway-referencing, the direct kinematic feedback may enhance ability to reduce proprioceptive information by servo-controlling more closely to actual ankle motion. For assessment, kinematics measurements can potentially increase sensitivity for detection of balance disorders, because it may be possible to discriminate between body sway and acceleration and to determine the phase relationship between ankle and hip motion.

Distal Tibia Fractures

Extra-articular distal tibia fractures involve distal tibia approximately 4 cm within tibia plafond with no articular extension. The proper preoperative care, planning and selection of surgical approach is very essential to prevent postoperative wound-related complications. We present a case of a 29 year female patient, presented with left ankle pain and swelling with a wound over the medial aspect of the ankle. X-ray of the left ankle showed extra-articular distal tibia fibula fracture with no neurovascular deficit. We managed both the fractures with open reduction and internal fixation using a single posterolateral approach. At present 1 year follow-up, the patient is having a good range of ankle motion with radiological union with no implant failure and wound-related complications. Extra-articular distal tibia fibula fracture fixation using single posterolateral approach is a viable alternative approach to medial or anterolateral approach in cases of medial or anterior soft tissue problems. It helps in getting a better functional outcome, early mobilisation with less wound-related complications.

Diaphyseal Fractures

Background: Elastic stable intramedullary nailing for the treatment of paediatric femur and tibial diaphyseal fractures was introduced by Prevot and colleagues in 1979. It follows three-point fixation principle that provides internal support in presence of cortical contact and an intact soft-tissue envelope. This technique has many advantages, including better reduction, dynamic axial stabilization, shorter hospitalization with early rehabilitation and low complication rate.Methods: This is a prospective observational study done at Kauvery Medical Centre, Trichy between May 2017 to May 2018 consisting of 39 children between age 5 to 16 years with diaphyseal fractures of femur and tibia. The fractures were treated by closed reduction and internal fixation with titanium elastic intramedullary nailing. The patients were evaluated clinically and radiologically and followed for an average of 6 months. Outcome was assessed using transcutaneous electrical nerve stimulation (TENS) scoring system used by Flynn et al.Results: Our series consisted of 39 patients (22 cases with fracture shaft of femur and 17 cases with fracture shaft of tibia), 33 males and only 6 females. Average time for radiological union was 9.89 weeks. All patients had full range of hip and ankle motion and 2 (5.1%) patients had mild restriction in knee flexion at 12 weeks.Conclusions: Elastic stable intramedullary nailing is an ideal method for treatment of paediatric femoral and tibial diaphyseal fractures due to lower complication rate and good functional outcome in comparison to other methods of treatment.
