Targeted Muscle Reinnervation for Transradial Amputation: Description of Operative Technique.
Targeted muscle reinnervation (TMR) is a revolutionary surgical technique that, together with advances in upper extremity prostheses and advanced neuromuscular pattern recognition, allows intuitive and coordinated control in multiple planes of motion for shoulder disarticulation and transhumeral amputees. TMR also may provide improvement in neuroma-related pain and may represent an opportunity for sensory reinnervation as advances in prostheses and haptic feedback progress. Although most commonly utilized following shoulder disarticulation and transhumeral amputations, TMR techniques also represent an exciting opportunity for improvement in integrated prosthesis control and neuroma-related pain improvement in patients with transradial amputations. As there are no detailed descriptions of this technique in the literature to date, we provide our surgical technique for TMR in transradial amputations.

Review Case ReportsAn Alternative Technique for External Fixation of Traumatic Intra-articular Fractures of Proximal and Middle Phalanx.
Intra-articular fractures of the proximal interphalangeal (PIP) joint are commonly treated with dynamic external fixation. Most commonly used is the Suzuki modification of the pins and rubber traction system (PRTS). There are a few other modifications of the PRTS external fixators. We present an alternative pin external fixator that is simple and effective. ⋯ The main advantages of the technique we describe are: (1) the compact design, making it less cumbersome for the patient compared with other PRTS external fixators; (2) it is straightforward to assemble and the device is easy to adjust in clinic if there is any loss of reduction; (3) the pin-balls prevent sharp ends of the wire protruding causing morbidity to the patient; (4) there is less chance of loss of traction compared with traction devices using rubber bands. It is a dynamic device, which allows mobilization of the joints reducing stiffness.

Case ReportsSingle-incision open reduction and internal fixation of comminuted trapezium fractures with distal radius cancellous autograft.
Trapezium fractures comprise approximately 3% to 5% of all hand fractures. Although operative management of intra-articular trapezium fractures can result in good functional outcomes, there is very little literature addressing specific operative techniques. We describe a technique for open reduction and internal fixation of severely comminuted, intra-articular trapezium fractures, utilizing autogenous cancellous bone graft from the distal radius.

The coronoid process serves as an important constraint that provides ulnohumeral joint stability. We describe a novel approach to coronoid fractures that minimizes surgical dissection, without compromising fracture visualization. We present the case of a 65-year-old woman who sustained an anteromedial facet fracture of the coronoid process. ⋯ It is a variation of the previously described approach by Taylor and Scham, although it can achieve a similar exposure without elevation of the entirety of the flexor-pronator mass. Our approach involves a limited skin incision, followed by elevation of enough of the flexor-pronator mass such that adequate visualization of the posterior medial collateral ligament (which was repaired), anteromedial facet, and the fractured fragment of coronoid were achieved. Moreover, this approach enables the course of the ulnar nerve to remain unaltered.

Minimally invasive procedure for the stabilization of the painful "prearthritic" carpometacarpal joint of the thumb.
The painful thumb carpometacarpal joint without arthritic changes with joint laxity is a common condition mainly affecting the female population in their early decades. Despite this, there is a lack of literature on the available treatment options. In the existing literature ligament reconstruction and extension osteotomy have both been described. ⋯ A standard postoperative protocol followed. No major complications occurred. According to preliminary experience and short-term follow-up results this technique is a comparatively safer, less invasive, and less aggressive procedure.
