The Impact of Complex Oral Rehabilitation on TMJ and Postural Alterations in Patients with Scapulohumeral Fractures.

Background and

Objectives

Temporomandibular disorders (TMDs) are prevalent conditions affecting the temporomandibular joint and associated musculature, arising from a complex interplay of biomechanical, neuromuscular, and psychosocial factors. Increasing evidence supports functional interconnections among the TMJ, cervical spine, and shoulder girdle, suggesting that dysfunction in one region may influence others; however, these relationships remain incompletely understood. This study aimed to evaluate the association between scapulohumeral trauma, postural abnormalities, and TMDs, and to assess their evolution following interdisciplinary rehabilitation. Materials and

Methods

A retrospective observational study with prospective follow-up was conducted in patients with scapulohumeral fractures associated with TMD and postural abnormalities. Postural parameters and the clinical features of temporomandibular disorders (TMDs) were evaluated at baseline and follow-up using a structured clinical assessment informed by the DC/TMD framework, together with clinical examination, electromyographic analysis, and mandibular mobility measurements. Postural evaluation was performed using digital baropodometric analysis (Free Med™ platform with FreeStep™ software, standard Medica sensor, Rome, Italy. Patients received individualized multidisciplinary treatment, including orthopaedic rehabilitation, occlusal splint therapy, physiotherapy (twice weekly), pharmacological management, and odonto-periodontal care. Statistical analyses were performed using non-parametric tests (p < 0.05).

Results

Significant postural improvement was observed (p < 0.01), with the proportion of patients with normal posture increasing from 0% to 22.2% and the proportion with moderate forward lean decreasing from 53.3% to 15.6%. TMD severity decreased progressively across evaluations (Friedman χ2 = 72.35, p < 0.01). No statistically significant differences were found between treatment groups with respect to postural outcomes, although descriptive differences in TMD improvement were observed at later evaluation points.

Conclusions

Interdisciplinary rehabilitation was associated with significant improvements in both postural alignment and TMD severity. Scapulohumeral trauma may be associated with alterations in TMJ function and overall posture, while multimodal therapy supports functional recovery. Further randomized controlled studies are needed to confirm these findings.
