Subtalar dislocation is characterized by simultaneous dislocation of the subtalar (talocalcaneal) and talonavicular joints, hence the name talocalcaneonavicular. These lesions can be grouped into four distinct categories: anterior and posterior, which are exceptional, lateral and medial. Medial subtalar dislocations are more frequent, are due to low-energy trauma and generally have good functional results. Anatomical reduction and stabilization of the subtalar joint and optimal management of all associated foot injuries are the key to good results.

Teriparatide, a recombinant human parathyroid hormone, is an anabolic treatment for osteoporosis with a high risk of fractures. Transient hypercalcemia is an adverse effect of teriparatide and usually resolves within 16h of teriparatide administration owing to its rapid absorption and elimination. Some cases of prolonged hypercalcemia have been reported, but these improved rapidly after teriparatide discontinuation. Here, we describe a rare case of teriparatide-induced hypercalcemia concomitant with acute kidney injury that persisted for four weeks. An 83-year-old woman began taking teriparatide for a vertebral fracture. The patient was immobilized by the fracture. Three weeks later, the patient developed hypercalcemia and acute kidney injury. However, hypercalcemia persisted for four weeks despite the discontinuation of teriparatide and fluid administration. Clinicians should be aware that teriparatide can induce severe hypercalcemia, especially in the setting of immobilization, and that hypercalcemia can persist for more than 3-4 weeks in patients with decreased kidney function.

UNASSIGNED: Osteogenesis imperfecta (OI) is a rare skeletal disorder characterized by bone fragility and deformities in both paediatric and adult populations. The occurrence of severe spondylolisthesis in OI patients is even more infrequent. However, there is no consensus regarding the optimal treatment approach for OI patients afflicted with severe spondylolisthesis. The selection of surgical procedures and the effective management of postoperative complications present significant challenges in this context.
UNASSIGNED: A 30-year-old male patient diagnosed with OI type IV (Sillence classification) underwent the lumbar laminectomy and postero-lateral fusion due to severe spondylolisthesis (grade Ⅲ). Following the surgery, the patient experienced postoperative screw pullout while on bedrest. However, aside from experiencing back pain, there were no neurological symptoms present. To address this issue, the patient received salvage treatment in the form of cast immobilization combined with bisphosphonates. At the 3-year follow-up, the patient exhibited absence of sciatic nerve pain and reported mild numbness in the lower extremities. Moreover, the patient demonstrated the ability to ambulate a distance exceeding 1500 m. Nevertheless, the persistence of sexual dysfunction was observed.
UNASSIGNED: This study presented the initial instance of surgical complications observed in patients with severe spondylolisthesis and OI. This highlights the importance to exercise meticulous caution and thoroughness when assessing surgical interventions.
UNASSIGNED: In cases where the fixation fails to offer adequate biomechanical stability, the administration of bisphosphonates and robust immobilization remains crucial, even in the presence of complications.

Background  Surgery is a major transient risk factor for venous thromboembolism (VTE). However, the impact of major surgery as a VTE trigger has been scarcely investigated using a case-crossover design. Aim  To investigate the role of major surgery as a trigger for incident VTE in a population-based case-crossover study while adjusting for other concomitant VTE triggers. Methods  We conducted a case-crossover study with 531 cancer-free VTE cases derived from the Tromsø Study cohort. Triggers were registered during the 90 days before a VTE event (hazard period) and in four preceding 90-day control periods. Conditional logistic regression was used to estimate odds ratios (ORs) with 95% confidence intervals (CIs) for VTE according to major surgery and after adjustment for other VTE triggers. Results  Surgery was registered in 85 of the 531 (16.0%) hazard periods and in 38 of the 2,124 (1.8%) control periods, yielding an OR for VTE of 11.40 (95% CI: 7.42-17.51). The OR decreased to 4.10 (95% CI: 2.40-6.94) after adjustment for immobilization and infection and was further attenuated to 3.31 (95% CI: 1.83-5.96) when additionally adjusted for trauma, blood transfusion, and central venous catheter. In a mediation analysis, 51.4% (95% CI: 35.5-79.7%) of the effect of surgery on VTE risk could be mediated through immobilization and infection. Conclusions  Major surgery was a trigger for VTE, but the association between surgery and VTE risk was in part explained by other VTE triggers often coexisting with surgery, particularly immobilization and infection.

UNASSIGNED: A short-term immobilization of one hand affects musculoskeletal functions, and the associated brain network adapts to the alterations happening to the body due to injuries. It was hypothesized that the injury-associated temporary disuse of the upper limb would alter the functional interactions of the motor cortical processes and will produce long-term changes throughout the immobilization and post-immobilization period.
UNASSIGNED: The case participant (male, 12 years old, right arm immobilized for clavicle fracture) was scanned using optical imaging technology of fNIRS over immobilization and post-immobilization. Pre-task data was collected for 3 min for RSFC analysis, processed, and analyzed using the Brain AnalyzIR toolbox. Connectivity was measured using Pearson correlation coefficients (R) from NIRS Toolbox\'s connectivity module.
UNASSIGNED: The non-affected hand task presented an increased ipsilateral response during the immobilization period, which then decreased over the follow-up visits. The right-hand task showed a bilateral activation pattern following immobilization, but the contralateral activation pattern was restored during the 1-year follow-up visit. Significant differences in the average connection strength over the study period were observed. The average Connection strength decreased from the third week of immobilization and continued to be lower than the baseline value. Global network efficiency decreased in weeks two and three, while the network settled into a higher efficient state during the follow-up periods after post-immobilization.
UNASSIGNED: Short-term immobilization of the upper limb is shown to have cortical changes in terms of activations of brain regions as well as connectivity. The short-term dis-use of the upper limb has shifted the unilateral activation pattern to the bilateral coactivation of the motor cortex from both hemispheres. Resting-state data reveals a disruption in the motor cortical network during the immobilization phase, and the network is reorganized into an efficient network over 1 year after the injury. Understanding such cortical reorganization could be informative for studying the recovery from neurological disorders affecting motor control in the future.

Introduction: Head and neck cancer patients have high rates of psychological distress, which may be exacerbated by the treatments they receive. Many patients who undergo radiation therapy report significant anxiety associated with the thermoplastic mask required for immobilization during treatment. Case Description: This report presents two examples of head and neck cancer patients reporting high mask anxiety, along with a history of claustrophobia, who expressed concern about their abilities to initiate and adhere to treatment. Both were referred to supportive care psychology before radiation treatment initiation. With counseling and the use of systematic desensitization, they were successfully able to complete their treatments. Discussion: Results of these case reports highlight the value of integrating early supportive care in the treatment of head and neck cancer and support the need for further study in future randomized controlled trials.

Since the beginning of the novel coronavirus disease-2019 (COVID-19) pandemic, physical medicine and rehabilitation specialists have played an important role in fighting this disease apart from the pulmonary rehabilitation. As a high number of patients have needed immobilization and intensive care unit (ICU) treatment, many complications have emerged inevitably. Heterotopic ossification (HO) is one of these complications. Herein, we present a case of young male patient who had widespread HO in his shoulders, elbows, and hips. Although he managed to survive, he still has difficulty in ambulation and daily living activities. Given the continuing high prevalence of COVID-19, many patients would need immobilization and ICU treatment. Therefore, causes of HO should be scrutinized, physicians and caregivers need to raise vigilance, and comprehensive protective measures should be put in place. On the other hand, as HO is used to be diagnosed quite frequently in the patients with neurological diseases, diagnosis of HO in the COVID-19 patients should not automatically be linked to the stay in the ICU. Yet, it is a fact that impaired immune response is prevalent both in COVID-19 and HO. The correlation between COVID-19 and HO is remarkable, but further research is needed to establish a causal relationship.

Joint flexion to diminish the gap and avoid nerve grafts fell into disuse for decades, but recently attention for using this technique was regained. We report a case series of nerve suture under joint flexion, ultrasound monitoring, and physiotherapy. Our main objective was to determine how effective this multimodality treatment is.
A retrospective review of 8 patients treated with direct repair with joint flexion was done. Depending on the affected nerve, either the knee or the elbow was flexed intraoperatively to determine if direct suturing was possible. After surgery, the limb was held immobilized. Through serial ultrasounds and a physiotherapy program, the limb was fully extended. If a nerve repair rupture was observed, the patient was re-operated and grafts were used.
Of the eight nerve sutures analyzed, four sustained a nerve rupture revealed by US at an early stage, while four did not show any sign of dehiscence. In the patients in whom the nerve suture was preserved, an early and very good response was observed. Ultrasound was 100% accurate at identifying nerve suture preservation. Early detection of nerve failure permitted early re-do surgery using grafts without flexion, ultimately determining good final results.
We observed a high rate of dehiscence in our group of patients treated with direct repair and joint flexion. We believe this was due to an incorrect use of the immobilization device, excessive movement, or a broken device. In opposition to this, we observed that applying direct nerve sutures and joint flexion offers unusually good and fast results. If this technique is employed, it is mandatory to closely monitor suture status with US, together with physiotherapy providing progressive, US-guided extension of the flexed joint. If nerve rupture occurs, the close monitoring dictated by this protocol should ensure the timely application of a successful graft repair.

Cerebral palsy (CP) is a non-progressive, neurological disorder often resulting in secondary musculoskeletal impairments affecting alignment and function which can result in orthopaedic surgery. Neuromuscular electrical stimulation (NMES) is a modality that can be used for rehabilitation; however, NMES immediately following orthopaedic surgery in children with CP using surface electrodes has not been previously reported. The purpose of this case series is to describe the novel use of NMES in the acute rehabilitation phase directly after orthopaedic surgery. This case series included three children with spastic diplegia CP, Gross Motor Function Classification System level II who underwent Single Event Multi-Level orthopaedic Surgery. Each long leg cast contained window cast cut-outs to allow for surface electrode placement for daily NMES intervention to the quadriceps muscles while immobilized. Children were assessed pre- and post-operatively using the Functional Mobility Scale (FMS), Gross Motor Function Measure (GMFM-66), and 6-Minute Walk Test (6MWT). All children demonstrated no adverse effects using NMES intervention and had improvements in the 6MWT. Most children demonstrated gains in the FMS and GMFM-66. Use of NMES through window cast-cuts in a long leg cast is a novel practice approach for delivery of early rehabilitation following lower extremity orthopaedic surgery.

Prolonged immobilization and, in particular, mechanical ventilation, have been linked to muscle atrophy. Anecdotal reports in the literature describe rhabdomyolysis as a potential late complication of COVID-19 infection which, in severe cases, may coexist with fluid collections. We report a case of a 28-year-old patient that had been recently hospitalized with SARS-CoV-2 pneumonia, with need for invasive ventilation support. Days after being discharged, the patient presents with retrosternal thoracalgia irradiating to the left upper limb. On physical examination, abduction and external rotation were limited due to pain complaints and there was soft tissue swelling of the corresponding shoulder and arm. Imaging evaluation was essential to establish the underlying condition, revealing bilateral arthritis communicating with large rotator cuff collections, which was considered of septic nature.
