False Joint – Symptoms and Treatment Options

Pseudoarthrosis, commonly referred to as a false joint, represents a pathological condition in which normal bone healing fails to occur following trauma or fracture. Instead of proper osseous union, structural defects emerge within the bone, filled with fibrous connective tissue and exhibiting abnormal mobility. In Polish medical terminology, this term encompasses all instances of nonunion, whereas international literature distinguishes between two phenomena: classic nonunion (e.g., due to osteoporosis) and pseudoarthrosis, where nonunion is accompanied by deformity of the bone ends. This disorder most frequently affects the scaphoid bone in the wrist, as well as long bones such as the humerus or tibia, where disrupted regenerative processes lead to the formation of a pathological, mobile articulation.

It is essential to emphasize that the formation of so-called pseudarthrosis often stems from an erroneous interpretation of a patient’s clinical presentation, which consequently allows the underlying pathology to remain concealed and progress unchecked over extended periods. To prevent such diagnostic inaccuracies, a thorough evaluation using advanced imaging modalities and laboratory assessments is imperative, enabling either the definitive exclusion or confirmation of this condition. Among the primary diagnostic procedures, conventional radiography (X-ray) stands out for its ability to visualize bony structures, while bone scintigraphy—a radioactive isotope-based technique—facilitates precise assessment of bone tissue metabolism and the detection of potential pathological foci. The most characteristic symptoms associated with pseudarthrosis include: – mechanically induced, severe pain that exacerbates upon loading or mobilizing the affected body segment; – significant restriction of physiological joint mobility coupled with the emergence of abnormal, non-physiological movement within the lesion site; – localized inflammatory manifestations such as soft tissue swelling, elevated skin temperature, and erythema in the vicinity of the involved area; – visible contour deformities of the joint, which may be palpable or observable during physical examination.

The therapeutic management of pseudarthrosis—commonly referred to as nonunion fractures—represents a sophisticated, multimodal process designed to facilitate osseous consolidation while mitigating persistent pain and functional impairment. Central to this approach are targeted physical modalities, including cryotherapy to attenuate inflammatory mediators, high-intensity laser therapy (HILT) to enhance cellular repair mechanisms, pulsed electromagnetic field (PEMF) exposure to stimulate osteoblastic activity, and therapeutic ultrasound to promote collagen fiber alignment and tissue granulation. To augment regional perfusion and metabolic efficiency within the affected anatomical site, clinicians frequently employ a synergistic combination of deep-tissue massage, myofascial release techniques, and passive range-of-motion exercises. Nutritional optimization constitutes another critical pillar of treatment, emphasizing the consumption of complete proteins (e.g., lean meats, legumes), calcium-rich foods (e.g., fortified dairy or leafy greens), and vitamin D3 supplements to rectify biochemical deficiencies that may impede fracture healing. In refractory cases marked by extensive bone loss or recurrent aseptic inflammation, advanced biologics such as autologous mesenchymal stem cell (MSC) transplantation may be indicated. This procedure involves harvesting progenitor cells from the patient’s iliac crest, concentrating them via centrifugation, and reimplanting them into the nonunion site to induce de novo bone formation. Serial monitoring of bone mineral density (BMD) through dual-energy X-ray absorptiometry (DEXA) scans permits dynamic assessment of therapeutic efficacy and informs prognostic adjustments. When conservative measures prove inadequate, surgical intervention becomes necessary. Open reduction and internal fixation (ORIF) utilizing metallic hardware—such as locking plates, intramedullary rods, or cortical screws—provides rigid stabilization essential for secondary bone healing. For smaller articulations (e.g., wrist or ankle joints), arthroscopic techniques are favored, enabling precise anatomical realignment of fractured segments followed by grafting with autogenous bone (e.g., fibular strut) or biocompatible synthetic scaffolds.
