We report an unusual case of proximal interphalangeal joint locking of the ring finger due to the neglected flexor digitorum profundus avulsion. Although rare, it should be noted that locking is a potential complication after this injury. Source

Calcium pyrophosphate dihydrate deposition disease typically involves the wrist joint in the form of calcifications of the triangular fibrocartilage and the distal radioulnar joint. We describe an 87-year-old male who presented to us with asymptomatic form of deposition with multiple flexor tendon calcifications causing chronic median nerve compression. Simple carpal tunnel decompression relieved his median nerve symptoms. Source

This experiment establishes the principles of using the compound muscle action potential (CMAP) as a possible postoperative monitor for free muscle grafts. Twenty rabbits were divided into two groups of ten each to investigate the effects of ischemia on CMAP of the muscles. Rectus femoris model was used and contralateral muscle was used as control. In all muscles total normothermic ischemia of 1.5 hours to mimic the time needed for transfer and inset of the flap was followed by occlusion of the artery in one group and vein in another group after 3 hours. During this ischemia of 1 hour, the CMAP amplitudes decreased and the latencies were prolonged. Latency prolongation was detected within 10 minutes of total, arterial, or venous ischemia. During the revascularization, both amplitude and latency improved, but not to the original values at the start. The results show that CMAP monitoring can provide easily detectable, objective indication of vascular compromise to a muscle graft within as early as 10 minutes of total, arterial, and venous ischemia. Changes in latency are more constant and predictable compared with amplitude changes. This method can provide continuous monitoring and can be used in buried muscle grafts.

Anatomic variations in branching pattern of axillary artery (AxA) are common and typically involve subscapular artery (SsA) and posterior circumflex humeral artery (PCHA). Several skin and muscle flaps are based on the branches of AxA. Furthermore, these branches are frequently used as recipient vessels in functioning free muscle transfers for upper extremity reconstruction and in breast reconstruction. Accurate knowledge of the normal anatomy and variations in branching pattern of AxA is of significant clinical importance for the reconstructive microsurgeon. The purpose of this article is to report the variable branching pattern of AxA based on multidetector-row computed tomography angiography study of 62 upper extremities. The thoracoacromial artery consistently originated from the first or second part of AxA. The classic origin and branching patterns of SsA and PCHA were observed in 21 cases (33.9%). Anatomic variations of SsA and PCHA were observed in 41 upper extremities (66.1%). In addition to the classic pattern, five distinct variations were noted. © 2013 by Thieme Medical Publishers, Inc.

Purpose: We reviewed 18 patients who had received double free muscle transfers and wrist arthrodesis to determine the effect of the stiff wrist on digital motion and function. Methods: The patients were 15 men and 3 women with a mean age of 24 years. We determined the total active motion of the metacarpophalangeal and interphalangeal joints just before performing the arthrodesis and at final follow-up. We recorded the Disabilities of the Arm, Shoulder, and Hand functional score at the same times. Results: All of our patients showed evidence of fusion at a mean of 12 ± 2 weeks (range, 1015 wk). The digital mean total active motion was 39° ± 21°before arthrodesis and 49°± 25°after arthrodesis. Preoperative Disabilities of the Arm, Shoulder, and Hand scores significantly decreased after fusion. Three cases were complicated postoperatively by wound hematoma. Five patients required wrist arthrodesis hardware removal because of skin irritation. Conclusions: Wrist fusion in patients receiving double free muscle transfers resulted in improved finger range of motion and overall hand function. Type of study/level of evidence: Therapeutic IV. © 2012 American Society for Surgery of the Hand. Source
