RESUMEN
Extensor carpi radialis brevis (ECRB) transfer to the hamate bone is a novel procedure that offers a new surgical treatment option for select patients with midcarpal instability (MCI) who do not respond to conservative treatment. We present our early experience with this procedure. In total, 12 patients (13 wrists) were reviewed with a follow-up duration ranging from 1 to 6 years. Complications and changes in active range of motion (AROM) were noted. Patient related outcome was measured using the Patient Rated Wrist/Hand Evaluation (PRWHE) questionnaire, amongst others. Two patients failed to show a positive response to the surgery. ECRB transfer to the ulnar side of the wrist is a new procedure that offers a potential option for the surgical treatment of MCI in select patients; however, further biomechanical and clinical studies are required. The level of evidence for this study is IV (therapeutic).
RESUMEN
The midline of the ring finger is classically considered as the neural watershed between the median and ulnar nerve sensory territories on the palmar surfaces of the fingers. Variations of this division exist and may be explained by a communicating branch between the third and fourth common digital nerves. The palmar sensibility patterns of fingers were assessed with Semmes Weinstein filaments after either a complete median or an ulnar nerve transection in 43 patients. Eight out of nine observed sensibility patterns could be explained by known anatomic types and subtypes of the communicating branch. The type of communicating branch, but not its subtype, could be established in the one remaining pattern.
