Reconstructive options for multidigit or soft tissue defects of the hand are varied, yet complex hand defects remain particularly challenging. These cases often necessitate microvascular reconstruction using osteocutaneous free flaps to achieve functional limb salvage. This paper presents two cases of osteocutaneous lateral arm free flap surgery performed at our institution, demonstrating the efficacy of this technique in managing complex hand defects. One case involved a severe crushing injury on an index finger with only the ulnar neurovascular bundle remaining, and the other involved a crushing injury on the first web space with severe comminution of the first metacarpal bone. After an emergency simple debridement, reconstructive surgery using the osteocutaneous lateral arm free flap was performed a few days later. Both cases healed without necrosis. Although both patients lost interphalangeal joint function, they were able to maintain grasping function and finger length without amputation. The osteocutaneous lateral arm free flap is an effective reconstruction method for addressing small to moderate-sized segmental bone and soft tissue defects of the hand caused by trauma. This procedure can be conveniently performed in a single session under regional anesthesia.

Purpose: Treatment options for distal radius malunion with dorsal angulation include open-wedge osteotomy using a volar approach or closed-wedge osteotomy. An advantage of open-wedge osteotomy is that it preserves the length of the radius; however, it often requires bone grafting and presents difficulties in achieving reduction. In contrast, closed-wedge osteotomy makes correction easier, but it requires ulnar shortening osteotomy. Therefore, in this study, we propose an effective surgical method that compensates for the disadvantages of both techniques by using half-wedge osteotomy and rotational placement. Methods: This study presents five cases of distal radius corrective osteotomy and ulnar shortening osteotomy performed at our institution using half-wedge osteotomy and rotational placement for distal radius malunion between 2017 and 2021. Surgical efficacy was evaluated by assessing radiographic changes, visual analog scale scores, and the quick Disability of the Arm, Shoulder, and Hand score postoperatively. Results: The bone union was achieved in all cases, and computed tomography scans performed 6 months postoperatively showed ongoing bone healing. Postoperative dorsal tilt was restored to the normal range, and the clinical scores improved. Conclusion Half-wedge osteotomy and reverse repositioning for dorsal malunion distal radius are effective treatments, as they facilitate the correction of malunion, reduce the need for ulnar shortening length, and eliminate the need for bone grafting from the iliac crest.

OBJECTIVES: In this study, we sought to evaluate the association between smoking status and subclinical coronary atherosclerosis, as detected by coronary computed tomography angiography (CCTA), in asymptomatic individuals. METHODS: We retrospectively analyzed 9,285 asymptomatic participants (mean age, 53.7±8.0 years; n=6,017, 64.8% male) with no history of coronary artery disease (CAD) who had undergone self-referred CCTA. Of these participants, 4,333 (46.7%) were considered never smokers, 2,885 (31.1%) former smokers, and 2,067 (22.3%) current smokers. We assessed the degree and characteristics of subclinical coronary atherosclerosis using CCTA, with obstructive CAD defined as a diameter stenosis of at least 50%. RESULTS: Compared with never-smokers, former smokers exhibited no significant differences in the probabilities of obstructive CAD, any coronary plaque, calcified plaque, or mixed plaque, as determined using adjusted odds ratios (aORs; p>0.05 for all). However, the risk of non-calcified plaque was significantly higher in former smokers (aOR, 1.34; 95% confidence interval [CI], 1.00 to 1.78; p=0.048). Current smokers had significantly higher rates of obstructive CAD (aOR, 1.46; 95% CI, 1.10 to 1.96; p=0.010), any coronary plaque (aOR, 1.41; 95% CI, 1.20 to 1.65; p<0.001), calcified plaque (aOR, 1.32; 95% CI, 1.13 to 1.55; p=0.001), non-calcified plaque (aOR, 1.72; 95% CI, 1.28 to 2.32; p<0.001), and mixed plaque (aOR, 2.00; 95% CI, 1.39 to 2.86; p<0.001) compared to never smokers. CONCLUSIONS This cross-sectional study revealed a significant association between current smoking and subclinical coronary atherosclerosis, as detected on CCTA. Additionally, former smoking demonstrated an association with non-calcified plaque, indicating elevated cardiovascular risk.
