Background: The purpose of this clinical research is to report our results using the free distal ulnar artery perforator flap for resurfacing complex tissue defects in the finger, and to provide empirical reference for the treatment of subsequent clinical cases.
Methods: In our research, eight patients with complex skin defects were treated with free distal ulnar artery perforator flaps. There were 4 index, 3 long, and 2 ring fingers. All the flaps were raised from the ipsilateral ulnar lateral wrist. The donor sites were covered with a full thickness skin graft or closed by direct suture.
Results: Comprehensive analysis of the clinical treatment process of eight patients, all flaps survived completely without any necrosis during the 6-18 months follow-up. The patients were satisfied with the finger mobility, the sensation function, and the aesthetic appearance.
Conclusions: Resurfacing complex tissue defects in the finger using the free perforator flap in a single stage, especially when the defect is medium in size and accompanied by digit nerve loss, is a valuable technique to achieve satisfaction in both sensation and aesthetic appearance. The ulnar artery perforator flap seems to be a reliable and flexible flap for addressing complex hand injuries with tissue loss.

Rare bilateral vascular variations of the upper limb: a cadaveric case study.

Arterial variations in the upper limb are of significant clinical importance, especially in procedures such as venepunctures, coronary artery bypass grafts, trauma reconstructive surgeries, brachial plexus nerve blocks, and breast reconstructions. This report presents previously undocumented arterial variations in the upper limbs in a 95-year-old female cadaveric donor. We observed bilateral superficial ulnar arteries originating at the cubital fossa, deviating from the previously reported origin at the proximal brachial artery.

We present a case of arterial bypass for extensive stenosis of the ulnar artery and superficial palmar arch. The ulnar artery and the superficial palmar arch were bypassed using the great saphenous vein. Postoperatively, blood flow to the affected fingers gradually improved and the pain disappeared.

Article Synopsis
- Peripheral nerve neuromas can be difficult to treat, particularly when they are scar-tethered to important structures.
- A patient with delayed neurotmesis of the median and ulnar nerves had significant scarring near the repaired brachial artery.
- To restore the median nerve continuity, surgeons opted to leave the scarred segment in place and used a "fly-over" graft technique with sural nerve autografts to avoid damaging the artery.
Biomechanical evolutionary advantage of flexor pollicis longus accessory head and topographical association with neurovascular structures.

The human upper limb has undergone various evolutionary myologic changes, accompanied by corresponding modifications in the anatomical course of neurovascular structures. In this study, we aimed to elucidate the emergence of the accessory head of the flexor pollicis longus (AHFPL) muscle as a beneficial biomechanical evolutionary development and its topographical relationship with adjacent neurovascular structures. In this pursuit to understand this phenomenon, dissections were conducted on sixty-two upper limbs from thirty-one cadavers.

Introduction: Giant cell tumor (GCT) of the bone, although benign, poses significant challenges due to its locally aggressive nature and high recurrence rates post-surgical intervention. Among skeletal GCTs, those affecting the distal radius present unique difficulties, especially when fungating masses encase vital structures such as blood vessels.
Case Report: We present a case of a 28-year-old male with a recurring GCT of the distal radius, where limb-preserving surgery was successfully performed despite encasement of the radial artery.
