IntroductionWe previously reported transferring seventh cervical (C7) nerve from unaffected side to affected side in patients with spastic hemiplegia due to chronic cerebral injury, to improve function and reduce spasticity of paralyzed upper limb. In the clinics, some patients also reported changes of spasticity in their lower limb, which could not be detected by routine physical examinations. Pennation angle of muscle can indirectly reflect the condition of spasticity. The purpose of this study was to evaluate whether this upper limb procedure may affect spasticity of lower limb, using ultrasonography to detect changes of muscle pennation angle (PA).MethodsTwelve spastic hemiplegia patients due to cerebral injury including stroke, cerebral palsy, and traumatic brain injury, who underwent C7 nerve transfer procedure, participated in this study. B‐mode ultrasonography was used to measure PA of the gastrocnemius medialis (GM) muscle at rest preoperatively and postoperatively. The plantar load distribution of the lower limbs was evaluated using a Zebris FDM platform preoperatively and postoperatively.ResultsThe PA of the GM was significantly smaller on the affected side than that of unaffected side before surgery. On the affected side, the postoperative PA was significantly larger than preoperative PA. On the unaffected side, the postoperative PA was not significantly different compared to preoperative PA. The postoperative plantar load distribution of the affected forefoot was significantly smaller than preoperative load distribution, which was consistent with ultrasonography results.ConclusionsThis study indicates that C7 nerve transfer surgery for improving upper limb function can also affect muscle properties of lower limb in spastic hemiplegia patients, which reveals a link between the upper and lower limbs. The interlimb interactions should be considered in rehabilitation physiotherapy, and the regular pattern and mechanism need to be further studied.

“…A randomized controlled trial by Zheng et al [24] showed that 3DPMassisted surgical planning had shorter operation duration, less blood loss and X-ray exposure, as well as better anatomic reduction and clinical outcomes than conventional surgery in 100 patient with Pilon fractures. However, few studies have used 3DPM in combination with external xators for the treatment of lower extremity deformity [25,26,27]. To the best of our knowledge, no study has reported the application of 3DPM in the correction of PAC with external xators.…”

Background: Gradual distraction with external fixators such as Ilizarov frame has been widely used for the treatment of severe postburn ankle contracture (PAC). However, the application of external fixator is complex and conventional surgical planning based on 2D imaging is compromised due to a lack of spatial geometry and tactile feedback. The purpose of this study was to evaluate the surgical planning with patient-specific 3D-printed models (3DPM) for the treatment of PAC with external fixators. Methods: A two-centered retrospective cohort study, composed of consecutive patients who underwent external fixation for the treatment of severe PAC, was implemented. Patients were divided into two cohorts (3DPM group vs. Control group) according to whether 3DPM was used for preoperative surgical planning. The primary outcome variable was operation duration. Other outcome variables included improvement in metatarsal-tibial angle (MTA), range of motion (ROM), American Orthopedic Foot and Ankle Society (AOFAS) scores, and complications. Results: Between January 2008 and June 2018, ten patients with an average age of 23.8±14.1 yeas were treated for PAC at two centers. 3DPM were used for surgical planning in 5 patients. 3DPM group had significantly shorter operation duration than the control group (2±0.3 hours vs. 3.2±0.3 hours, p=0.0001). The comparison of preoperative, after removal of external fixator, and follow-up MTA, ROM, and AOFAS between the 3DPM and control group showed no significant differences. A plantigrade foot was achieved and gait was substantially improved in all patients at the final follow-up. Pin-tract infections occurred in 2 patients (one in each group) during distraction and were treated with wound care and oral antibiotics. Conclusion: The results of this study show that surgical planning using patient-specific 3DPM significantly reduced the operation duration while providing similar improvements in MTA, ROM, and AOFAS scores compared to traditional surgical planning for the correction of severe PAC with external fixators.

“…When assessing the outcomes from the treatment of lower limb diseases, it is important to evaluate the limb function in addition to routine clinical and radiological assessment [3], [5], [6], [23]. From the orthopaedic and patient point of view, after the treatment, an assessment should be carried out of the biomechanics of the musculoskeletal system [5], [6], [17], [23]- [25].…”

Purpose: The biomechanics of the musculoskeletal system in patients after tibial nonunion treatment using the Ilizarov method have not yet been fully explored. From the orthopaedic and patient point of view, after the treatment, an assessment should be carried out of the biomechanics of the musculoskeletal system. The aim of this study was to assess the body balance of patients treated with the Ilizarov method for tibial nonunion. Methods: The research group included 24 individuals with a mean age of 55 years, who were treated for aseptic tibial nonunion with the Ilizarov method. The control group was matched to the study group in terms of gender and age, and consisted of 32 subjects with a mean age of 50.5 years and no significant medical history. This study evaluated the balance of patients with the use of pedobarography. Results: In the control group, a statistically significantly shorter path of centre of gravity was observed. There were no statistical differences between the study and control groups for the field area of the centre of gravity. There were no statistical differences between the study and control groups for the minor axis length or major axis length of the centre of gravity. There was a relationship between the centre of pressure path length and the age of the participants in both the control group and the study group. Conclusions: Treatment of patients with tibial nonunion with the Ilizarov fixator achieves similar balance to healthy volunteers. In the pedobarographic evaluation, patients treated for tibial nonunion using the Ilizarov method had similar statics of the musculoskeletal system to healthy volunteers.
