Active orthopaedic technology
that senses, predicts,
and acts autonomously.

1 MHz transducer array transmits through the cast shell, measuring acoustic impedance changes that correlate with callus density and mineralisation, calibrated against radiographic union staging.

280 μm hollow titanium micro-needles deliver NSAIDs, low-dose opioids, or ketamine subcutaneously. Dosing is computed by a PK/PD model that incorporates patient weight, pain NRS score, and cortisol proxy levels.

Continuous limb temperature mapping (16 thermal sensors) plus bioimpedance-derived pressure estimation. Alert fires when intracompartmental pressure exceeds 30 mmHg, giving a critical 4-hour advantage over clinical exam.

LSTM model trained on 52,000 longitudinal fracture cases produces a per-patient recovery roadmap: predicted soft-callus date, hard-callus date, and radiographic union, updated weekly with incoming sensor data.

Pulsed electromagnetic field coils (50 Hz, 1 mT) embedded in the cast shell deliver the FDA-cleared stimulation protocol automatically each night, and independent data shows 38% faster union time.

6-DOF inertial unit tracks joint angle, movement velocity, and symmetry during prescribed exercises. Haptic motor pulses provide real-time corrective cues; clinician receives weekly compliance and ROM reports.

Multi-frequency bioimpedance spectroscopy (5–500 kHz) quantifies extracellular fluid volume. Photoplethysmography array assesses limb perfusion index and detects DVT-suggestive waveform changes.

Two linear resonant actuators (LRAs) embedded in the inner shell deliver 80 Hz transcutaneous vibration bursts lasting 12 seconds. Stimulating fast-conducting Aβ nerve fibres via Gate Control Theory inhibits the itch signal from unmyelinated C fibres, verified against histamine-induced itch in Phase I skin studies. Patient-triggered via app or automated when a scratch-motion signature is detected by the IMU.

A thin hydrogel liner embedded with 150 μm phase-change wax microbeads carrying ceramide III, aloe barbadensis extract, and 5% urea. A resistive thin-film heater (37 °C, 200 mW) activates on demand through the patient app or on a scheduled 12-hour cycle, rupturing the bead shells and releasing emollient directly onto the skin surface without cast removal. Each cartridge provides a 7-day moisture supply.

Qi-compatible inductive coil charges the 300 mAh LiPo pack through the TPU shell. The battery achieves a 7-day life and charges fully in 90 minutes. Drug cartridge hot-swappable via magnetic latch without cast removal.
