“…Additional benefit of transposition may be attributed to increased nerve overlap during repair to assist in healing and regain of function. [ 8 ]. Unfortunately, the patient was lost to follow-up for us to perform this and track the repairs.…”

Ulnar nerve dysfunction following distal humerus fractures is a recognized phenomenon. There is no dominating consensus regarding the optimal management of the ulnar nerve during surgical intervention for these fractures between leaving the nerve in situ versus nerve transposition for better healing. Additional complexities arise in the case we present, in which there was an open fracture compounded with an ulnar nerve laceration from a traumatic injury with a machete knife. We review and discuss the management of ulnar nerve injuries associated with complex open fractures of the humerus for optimizing patient outcomes following these injuries.

Iatrogenic Nerve Injuries of the Upper Extremity

Iatrogenic nerve injuries may occur after any intervention of the upper extremity.Causes of iatrogenic nerve lesions include direct sharp or thermal injury, retraction, compression from implants or compartment syndrome, injection, patient positioning, radiation, and cast/splint application, among others.Optimal treatment of iatrogenic peripheral nerve lesions relies on early and accurate diagnosis.Advanced imaging modalities (e.g., ultrasound and magnetic resonance imaging) and electrodiagnostic studies aid and assist in preoperative planning.Optimal treatment of iatrogenic injuries is situation-dependent and depends on the feasibility of direct repair, grafting, and functional transfers.

“…This may allow for primary repair and improved functional outcomes while avoiding the need for nerve grafting. Nerve transposition to reduce a repair gap and diminish tension is not a novel concept and has been described for ulnar nerve repair at the elbow (Smetana et al., 2017). The goals of this cadaveric study were to quantify the shortened course of the deep ulnar motor branch using this technique and describe the clinical relevance it may have in nerve repair after transection.…”

Primary repair of a nerve is preferable over nerve grafting when a tension-free environment can be achieved. The purpose of this cadaveric study was to evaluate the facility of nerve-gap closure gained by removing the hamate hook, eliminating the circuitous path of the motor branch of the ulnar nerve in the hand. Six cadaveric specimens were dissected and the length of the motor branch coursing through Guyon’s canal before and after hamate hook excision and nerve transposition was recorded. Average length was significantly shorter in specimens after transposition, with a mean 21% reduction relative to the nerve’s original course. This knowledge may help guide surgeons on whether excision of the hamate hook will allow for primary repair of the nerve when a segmental defect or retraction and scarring of the nerve stumps is encountered.
