| Large-joint arthroplasty | Dense cortical bone and cancellous bone | Oscillating sawing, reaming, drilling, and broaching | High torque, stable cutting, and resistance to stalling under load | Variable speed control, balanced handpiece, quick accessory exchange, irrigation compatibility | Multiple attachments may be needed during one case; instrument turnover and sterile setup are important | Torque consistency, blade control, ergonomic fatigue, attachment availability, and cleaning instructions |
| Trauma fixation | Long bones, cortical bone, and metaphyseal bone | Drilling, screw preparation, plate contouring support, and limited sawing | Accurate drilling with controllable speed and sufficient torque for various bone densities | Forward and reverse modes, depth-control options, cannulation, and a broad range of drill attachments | The system should support rapid changes between drilling sizes and provide clear battery or power status | Chuck accuracy, runout, reverse performance, tactile control, and compatibility with planned instruments |
| Spine surgery | Vertebral bone, lamina, facet joints, and narrow surgical corridors | High-speed burring, drilling, and fine bone removal | Precise control, low vibration, and predictable speed response | Fine burr selection, foot-switch control, irrigation, low-profile attachments, and adjustable speed | Access and visibility are limited; cable or hose management and noise control can affect the operative field | Vibration, heat management, speed stability, handpiece size, burr retention, and control placement |
| Small-bone and hand surgery | Small cortical surfaces, phalanges, carpal bones, and metacarpals | Fine drilling, screw-hole preparation, and precision sawing | Fine control at low speed with minimal vibration and excellent visibility | Compact handpiece, lightweight design, low-speed range, small-diameter attachments, and precise trigger control | Handpiece bulk can obstruct the field; quick setup and accurate accessory selection improve efficiency | Ergonomics, low-speed responsiveness, chuck precision, visibility around the working tip, and accessory range |
| Sports medicine and arthroscopy | Joint surfaces, tunnels, anchors, and limited bone areas | Reaming, drilling, shaving, and preparation of bone tunnels | Controlled speed, accurate alignment, and effective fluid management | Cannulated attachments, compact profile, suction or irrigation integration, and responsive controls | The device must fit within the portal strategy and maintain visibility in a fluid-filled field | Cannulation, attachment length, control under irrigation, debris management, and compatibility with surgical accessories |
| Pediatric orthopedics | Smaller bones, thinner cortices, and growth-related anatomy | Precision drilling, small-scale sawing, and guided bone preparation | Fine control, low vibration, and appropriate power for smaller anatomy | Compact attachments, adjustable speed, small drill sizes, and clear depth or direction control | Instrument scale, surgeon visibility, and protection of nearby structures should be considered during setup | Control resolution, small accessory availability, thermal management, and ease of handling in confined spaces |
| Revision and complex reconstruction | Dense bone, scarred tissue areas, cement, and previously implanted materials | High-load drilling, controlled sawing, burr work, and removal of obstructing material | Broad operating range, high torque reserve, and reliable performance over prolonged use | Multiple handpieces, heavy-duty attachments, thermal monitoring, irrigation, and dependable power supply | Longer cases require backup batteries or power sources, organized accessory trays, and efficient instrument exchange | Continuous-duty performance, heat control, accessory durability, backup strategy, and reprocessing capacity |
