Objective To explore the surgical technique and clinical effects of free anterolateral thigh flaps with fascia lata for repair of dorsal tendon and soft tissue defect of ophisthenar.Methods From February,2014 to July,2016,dorsal tendon and soft tissue defect of ophisthenar in 13 cases was repaired by free anterolateral thigh flaps with fascia lata.The area of soft tissue defect was 5.0 cm×6.0 cm-9.0 cm×12.0 cm.Extensor tendon defect and bone exposure occurred in all cases.The area of flap was 6.0 cm×7.0 cm-10.0 cm×13.0 cm,while the area of anterolateral thigh flap was 3.0 cm×4.0 cm-6.0 cm×8.0 cm.The regular post-operatively followed-up was performed.Results All flaps survived.The donor sites healed well without skin graft.The followed-up time was 6-36 months with the average of 13 months.The appearance of the flap was good.The color and texture of flaps was similar to the dorsal skin of ophisthenar.Three female patients who were not satisfied with the flap appearance received the revision and the results were satisfactory.The activity of finger flexion and extension was satisfactory.All patients walked well without difficulty.According to the Upper Extremity Functional Evaluation Standard set up by Hand Surgery Branch of Chinese Medical Association,the function recovery result was excellent in 8 cases,good in 4 cases,and poor in 1 case.Conclusion It is a good method to use the free anterolateral thigh flaps with fascia lata to repair of dorsal tendon and soft tissue defect of ophisthenar.

Objective:To explore the surgical method and clinical effect of harvesting 2 ipsilateral free pedicled perforator flaps from a single donor site of superficial peroneal artery in reconstruction of 2 defects in same or adjacent digits.Methods:From November 2017 to August 2021, 12 patients with 2 defects in same or adjacent digits were treated in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital with 2 ipsilateral free pedicled perforator flaps from a single donor site of superficial peroneal artery. Among the patients, 1 had the defect in dorsal and palmar of index finger, 1 in thumb and index finger, 6 in index and middle fingers, 3 in middle and ring fingers, and 1 in ring and little fingers. The size of digit defects was 1.5 cm×0.8 cm-6.0 cm×3.5 cm. The size of flaps was 2.0 cm× 1.2 cm-8.0 cm×4.0 cm. All the patients were included in postoperative monthly follow-up to assess the recovery of recipient and donor sites at outpatient service, by telephone or WeChat.Results:All 24 flaps in 12 patients survived without vascular compromise and achieved 100% of survival rate. The follow-up period ranged from 4 to 18 months, with an average of 10 months. Six patients were treated with additional flap thinning and plastic surgery at 4 months after the primary surgery due to slightly bloated flaps. Otherwise, all the flaps in the recipient site had neither pigmentation, obvious hyperplasia nor scar pain. All flaps gained the protective sensations, however the assessment of TPD was not conducted. The flaps were wear-resist and had no ulceration. The texture of the flaps was soft with good elasticity, and the flap did not turn to purple or swelling when in cold. The functional recovery of 23 digits in 12 patients was evaluated according to the total active mobility (TAM) of the digits. It achieved excellent in 3 digits, good in 15 digits, and fair in 5 digits, with an excellent and good rate of 78.26%. A linear scar appeared at the donor site without obvious hyperplasia or scar pain. There were normal sensations around the scar and at the digit-tips. The blood supply to the digit-tips was normal.Conclusion:Harvest of multiple free pedicled perforator flaps from a single donor site of superficial peroneal artery is an effective method in reconstruction of 2 defects in same or adjacent digits at the same time. It has advantages of being a simple surgery procedure by sacrificing only one donor site. It achieves a minimal damage to the donor site and a reliable blood supply of the flap.

Under the combination of postgraduate education and standardized medical residents training, via exploring current situation, we put forward the limitations of routine rotation training, disconnection of theory and practice, inefficient of scientific ability. We arouse a new model by improving teaching model, enriching teaching content, optimizing teaching method, making better arrangement of rotations and cultivating scientific ability to provide references for enhancing the ability of clinical thinking, practice, scientific research and communication.

Objective:To summarise the clinical application and results of superficial peroneal artery perforator flaps in tiled reconstruction of thumbs and fingers.Methods:From June 2020 to June 2022, 8 patients with finger or thumb defects (4 thumbs, 2 index fingers and 2 middle fingers) received digit reconstruction in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital. Two thumbs (2 patients) were reconstructed with a free partial hallux nail flap combined with a free perforator flap of superficial peroneal artery and an iliac bone graft, 1 thumb was reconstructed with a free partial hallux nail flap combined with a free perforator flap of superficial peroneal artery, 1 thumb and 2 middle fingers were reconstructed with free perforator flaps of superficial peroneal artery combined with iliac bone grafts, and 2 index fingers were reconstructed with lobulated free perforator flaps of superficial peroneal artery. The sizes of the flaps were 1.8 cm×3.2 cm-4.0 cm×10.0 cm. Lengths of iliac crest were 1.5-4.0 cm. The donor sites were directly sutured in 5 patients, skin grafts in 2 and superficial peroneal artery perforator flap reconstruction in 1 patient. Postoperative observations included survival of the digits and healing of the bone grafts. Monthly scheduled postoperative follow-ups were conducted at outpatient clinics and via telephone or WeChat reviews, covering function and appearance of the reconstructed digits, impact on the function and appearance of donor sites as well as the satisfaction of patients.Results:All 8 reconstructed digits survived in one stage and all the 5 bone grafts healed at 3 to 4 months after surgery. The mean postoperative follow-up period was 10 months, ranged 4 to 20 months. The texture of the reconstructed digits was close to that of the recipient site and good in elasticity, without purplish while in cold, nor ulceration, obvious bloating and pigmentation. Sensation of the digit pulps was recovered to S 2 to S 3, and the sensation in touch, pain and temperature were restored. TPD was not checked. There was no noticeable hyperplasia nor pain in the recipient and donor sites. There was no obvious hyperplasia or pain at the donor sites for the hallux nail flap, and the skin grafts or flaps in the donor sites survived well without ulceration or pain and the function of the donor feet were not affected. Functions of the reconstructed digits were assessed according to the Functional Assessment Criteria for Thumb and Finger Reconstruction of the Society for Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 4 patients achieved in excellent and 4 in good. According to the University of Michigan Hand Profile Questionnaire (MHQ), patient satisfaction was found very satisfied with 4 patients and satisfied with the other 4 patients. Conclusion:The superficial peroneal artery perforator flap has advantages of thin and large area with pleasant texture, better sensation recovery and less damage to the donor site. It is an ideal flap for reconstruction of thumbs and fingers.

Objective:To investigate the surgical methods and clinical effects of free superficial peroneal artery perforator flap in repairing small and medium-sized thermal crush injury wounds in the hand.Methods:A retrospective observational study was conducted. From August 2018 to December 2021, 12 patients (19 wounds) with small and medium-sized thermal crush injury in the hand who met the inclusion criteria were hospitalized in Suzhou Ruihua Orthopaedic Hospital, including 5 males and 7 females, aged from 30 to 54 years. The area of the wound was from 2.5 cm×2.0 cm to 14.0 cm×3.5 cm, and all the wounds were repaired by using free superficial peroneal artery perforator flaps from lower leg on one side (including single flap, multiple flaps, and multiple flaps with one pedicle resected from the same donor site). The area of the flap was from 3.5 cm×3.0 cm to 16.0 cm×4.0 cm. The wound in the donor site was sutured directly. The vascular crisis and survival of the flap were observed after operation. The texture, appearance, color, hyperpigmentation, sensation, and two-point discrimination of the flap repaired area were followed up, as well as the hyperplasia of scar and pain condition in the donor and recipient sites. At the last follow-up, the curative effect of flap repair was evaluated by the comprehensive evaluation scale, and the extension and flexion functions of the reserved digital joint were evaluated by the total active movement systematic evaluation method recommended by American Academy for Surgery of Hand.Results:One flap developed arterial crisis on the first day after operation but survived after timely exploration. The other 18 flaps survived successfully after operation. Follow-up of 4 to 24 months after operation showed good texture and appearance in the flap repaired area; the color of the flap repaired area was similar to that of the normal skin around the recipient site, without pigmentation; the protective sensation was restored in all cases, but there was no two-point discrimination; there was no obvious hypertrophic scarring or pain in the donor or recipient site. At the last follow-up, the curative effect of flap repair was evaluated with 3 flaps being excellent and 16 flaps being good; the extension and flexion functions of the reserved digital joint were also assessed, being excellent in 8 fingers, good in 9 fingers, and fair in 2 fingers.Conclusions:The blood supply of superficial peroneal artery perforator flap is sufficient and reliable, and multiple flaps of this type or multiple flaps with one pedicle can be resected from one donor site. The use of this flap to repair small and medium-sized thermal crush injury wounds in the hand results in minimal damage to the donor area, and good postoperative appearance and texture of the flap.
