Replantation surgery for traumatically amputated digits involves reconnection of a severed digit with microsurgical techniques. It has evolved over half a century into a matured medical technique. However, a significant number of patients who are eligible for replantation upon arrival of the hospital do not wish to take the replantation surgery, instead, they opt for stump revision surgery. From July 2024 to August 2024, 320 patients with severed digits and indications for replantation, who were treated in a Tier-IIIA hospital in Southwest China from June 2020 to December 2023, were randomly selected by the Department of Upper Limb Repair and Reconstruction Surgery of Beijing Jishuitan Hospital, Guizhou Hospital. The medical records about surgical plans and outcomes of surgery were statistically analysed retrospectively. At the same time, interviews were conducted with five attending surgeons in the Department of Hand Surgery of the hospital. This article analyses the underlying reasons behind this phenomenon from a medical ethics perspective, and examines the standpoints of the patient and surgeon. This article also explores the ideal model for medical decision-making in digital replantation, and proposes improvements from various aspects. The aim of it is to enable the patients with traumatically amputated digits to make the most appropriate decisions without interference, thereby to minimise the impairment.

Objective:To investigate the effects of medial plantar artery perforator flap in the reconstruction of palmar scar contracture.Methods:This study was a retrospective observational study. From January 2016 to January 2023, 15 patients with palmar scar contracture who met the inclusion criteria were admitted to Guangzhou Peace Orthopedic Hospital, including 12 males and 3 females, aged 15 to 50 years. Before surgery, the Michigan Hand Outcomes Questionnaire (MHQ) scores for the affected hands ranged from 58 to 77, and the total active motion for the affected hands ranged from 190° to 220°. The skin and soft tissue defect area after scar excision on the palmar side of the affected hands was 5.2 cm×3.2 cm to 7.2 cm×6.0 cm. According to the location and area of the wounds, the defects were repaired using either medial plantar artery superficial perforator flaps or combined flaps of the cutaneous perforator of superficial branch of medial plantar artery and medial branch of medial plantar artery deep branch. The area of the harvested flaps was 5.5 cm×3.5 cm to 7.5 cm×6.8 cm. The donor site wounds on the feet were repaired using superficial circumflex iliac artery perforator flaps. Postoperatively, the survivals of the medial plantar artery perforator flaps and superficial circumflex iliac artery perforator flaps were observed. After survival of the flaps, patients were guided for rehabilitation exercises for the affected hands. Regular outpatient follow-up was conducted after surgery to observe the appearance, color, and texture of the medial plantar artery perforator flaps, and the recovery of foot function. At the final follow-up, the two-point discrimination distance of the medial plantar artery perforator flap was measured, the function of the affected hands was evaluated using the trial criteria for evaluation of partial function of upper extremity by the Hand Surgery Society of Chinese Medical Association and the MHQ.Results:Postoperatively, two patients experienced vascular crisis of the medial plantar artery perforator flaps, while the flaps survived after emergency exploration; the medial plantar artery perforator flaps and superficial circumflex iliac artery perforator flaps survived in other patients. Follow-up for 6 to 18 months postoperatively showed that the medial plantar artery perforator flaps had no bulky appearance, similar color and texture to the surrounding skin, and the foot functions such as running and jumping were not affected. At the final follow-up, the two-point discrimination distance of the medial plantar artery perforator flap ranged from 7 to 10 mm, with an average of 8 mm; the affected hand function was rated as excellent in 12 cases and good in 3 cases; the MHQ scores of the affected hand function ranged from 81 to 95, and the patients were satisfied with the postoperative appearance, pain relief, and functional recovery of the affected hand.Conclusions:The medial plantar artery perforator flap is used for the reconstruction of palmar scar contracture. The flap is easy to harvest, and has a high survival rate, resulting in good postoperative recovery of the flap sensation and function of the affected hand, and minimal donor site injury in the foot. It is therefore worthy of clinical promotion.

Objective:To evaluate the clinical effectiveness of the reconstruction of multiple digit-tip defects with transfer of polyfoliate perforator flaps of the fibular hallux.Methods:From January 2019 to June 2022, 15 patients had undergone reconstruction surgery for multiple digit-tip defects using polyfoliate perforator flaps of ipsilateral fibular hallux, with the first dorsal metatarsal artery as the pedicle, in the Department of Upper Limb Repair and Reconstruction Surgery, Guizhou Hospital of Beijing Jishuitan Hospital. The patients were 10 males and 5 females and aged 20 to 45 years old. Eight patients had the defects of thumbs and index fingers, 4 of thumbs and middle fingers, 2 of thumb, index and middle fingers and 1 of thumb, index and ring fingers. All the 15 digit injuries had nail bed defects to which reconstructive surgery were required. For the flaps of dorsal artery, flaps were 1.8 cm×2.0 cm-2.0 cm×3.1 cm in size and for those of plantar artery, the flaps sized 1.5 cm×2.0 cm-2.5 cm×3.0 cm. Donor site defects in the hallux were reconstructed with free superficial circumflex iliac perforator flaps. Postoperative follow-up lasted until 30th June 2023 and included visits to the outpatient clinic, WeChat and telephone reviews to assess the appearance, function and sensation recovery of the digits.Results:All the 15 flaps survived. During the 6 to 24 months (16 months in average) of postoperative follow-up, the appearance and texture of all flaps were found close to the healthy digits, with good nail growth and without deformity. TPD were found between 8.0 mm and 12.0 mm. The donor sites on the great toes that reconstructed with superficial circumflex iliac artery flaps were all survived well, and the incisions were satisfactorily healed without the functions of walking, running or jumping being significantly affected.Conclusion:The use of polyfoliate perforator flaps of fibular hallux for reconstruction of multiple digit-tip defects is an ideal surgical method due to the consistency of vascular anatomy, ease with flap harvest, similarity in the normal digital skin texture, and the capability to include a nail bed with the flap. A single donor from the hallux can simultaneously reconstruct two defects of digit-tip, making it an excellent treatment in the reconstruction of small-to medium-sized composite tissue defects in multiple digits.

Objective:To explore the clinical characteristics and experiences in diagnosis and treatment of severe hand injuries caused by chaff cutters.Methods:A retrospective analysis was conducted on 60 patients (193 digits) who had mangled hand injuries caused by chaff cutters and admitted to the Department of Upper Limb Repair and Reconstruction, Beijing Jishuitan Hospital Guizhou Hospital between January 2015 and June 2022. The patients were 39 males and 21 females, with 10 to 72 (mean 42.6) years old of age. The injuries involved 41 right hands and 19 left hands. The extent of hand injuries of soft tissue and bones varied from digit-tips to wrist. Among them, 5 digits were completely destroyed in 8 cases, 3 digits including thumb were destroyed in 12 cases, 4 digits including thumb were destroyed in 10 cases, 3 or more fingers without thumb were destroyed in 8 cases, simple hand destroyed in 8 cases, digits and palm destroyed in 8 cases, and total hand destroyed in 6 cases. The sizes of wound ranged from 1.8 cm×2.0 cm to 6.8 cm×15.6 cm. Based on the wound contamination and conditions of tissue damage, surgical treatment included debridement, stump trimming, in-situ replantation, transpositional replantation, venous bridging flap transfer and emergency or phased free second toe and free flap transfers. The flap sizes were 3.0 cm×5.0 cm-7.0 cm×16.0 cm. Both the reconstructed and flap donor sites were primarily closed in one stage. Postoperative follow-ups were conducted through regular visits of outpatient clinic or via WeChat interviews. The survival and functional recovery of flap and finger were observed.Results:Of the 60 patients, emergency orthotopic replantation of 112 digits were performed with survival of 96 digits; 16 digits transposition replantation were carried out with 12 survived; 5 digits received venous bridging flap transfer with 4 survived; all 5 Flow-through anteriolateral thigh perforator flaps (ALTPFs) were survived; all of 12 phase II digit reconstructions with free second toe transfer survived; and all 18 phase II free flap transfers survived [10 ALTPFs and 8 superficial circumflex iliac artery perforator flaps(SCIAPFs)]. Postoperative complications such as wound exudation and fever happened in 8 patients, and all were rectified after debridement and symptomatic anti-infection treatment. The follow-up ranged 6 to 18 months, with 12 months in average. Hand functions were assessed using the Michigan Hand Outcomes Questionnaire (MHQ), and the scores achieved at 20.3 to 72.8 points, with 42.6 points ± 16.6 points in average.Conclusion:Severe hand injuries caused by chaff cutters are severe and complicated. A thorough assessment of wound contamination and residual digits and tissues are required. Successful surgical outcomes can be achieved through emergency and elective surgery with multiple microsurgical techniques and multi-phased surgical reconstructions, although overall functional recovery of the injured hand is often not quite realistic.

Objective: To determine the effects of ω-3 polyunsaturated fatty acids from different sources on glucolipid metabolism in type 2 diabetic patients with dyslipidemia. Methods: We recruited participants from the diabetes specialist clinic at the Guanlin hospital in Yixing city, Jiangsu Province from February 2017 to March 2017. A total of 180 subjects were randomly assigned to 3 g/day fish oil (FO), perilla oil (PO), or fish oil mixed with linseed oil (FLO) for 6 months. The basic conditions and fasting venous blood sample were obtained from each study subject at baseline, after 6 months of intervention. Serum glucose and lipid metabolism were investigated. Results: A total of 156 subjects aged (62.6±8.6) years completed the final follow-up after 6 months (FO,54 subjects; PO,52 subjects; FLO,50 subjects). Among them,59 patients (37.8%) were male. Serum glucose, glycated hemoglobin, C peptide, insulin and homeostasis model assessment-insulin resistance were not significantly different among the three groups after 6 months. Serum triglyceride decreased, whereas high-density lipoprotein cholesterol increased in FO [1.33 (1.05,1.93) mmol/L, (1.36±0.29) mmol/L, respectively] compared with PO [1.71 (1.23, 2.17) mmol/L, (1.23±0.22) mmol/L, respectively] and FLO [1.51 (1.12, 2.22) mmol/L, (1.29±0.30) mmol/L, respectively] (P<0.05). Serum low-density lipoprotein cholesterol and apolipoprotein B decreased in PO [(2.60±0.57) mmol/L,(0.96±0.23) g/L, respectively] compared with FO [(2.89±0.76) mmol/L, (1.07±0.30) g/L, respectively] (P<0.05). Serum lipoprotein(a) decreased in FLO [130.7 (63.3,270.6) mg/L] compared with FO [137.4 (58.7,333.2) mg/L] (P<0.05). Serum free fatty acid decreased in FLO [(0.43±0.15) mmol/L] compared with PO [(0.53±0.22) mmol/L] (P<0.05). Conclusion The effects of ω-3 PUFA from different sources on glucose metabolism in type 2 diabetic patients with dyslipidemia are similar. Each of them has a good application prospect in improving lipid metabolism.
