Reconstruction of complex tissue defect of forearm with a chimeric flap composed of a sural neurocutaneous flap and a vascularized fibular graft: A case report

Management of segmental bone defects of the upper limb: a scoping review with data synthesis to inform decision making

PURPOSE

Injuries to the long bones of the upper limb resulting in bone defects are rare but potentially devastating. Literature on the management of these injuries is limited to case reports and small case series. The aim of this study was to collate the most recent published work on the management of upper limb bone defects to assist with evidence based management when confronted with these cases.

METHODS

Following a preliminary search that confirmed the paucity of literature and lack of comparative trials, a scoping review using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) was conducted. A literature search of major electronic databases was conducted to identify journal articles relating to the management of upper limb long bone defects published between 2010 and 2020.

RESULTS

A total of 46 publications reporting on the management of 341 patients were reviewed. Structural autograft, bone transport, one-bone forearm and the induced membrane technique were employed in an almost equal number of cases. The implemented strategies showed similar outcomes but different indications and complication profiles were observed.

CONCLUSION

Contemporary techniques for the management of post-traumatic upper limb bone defects all produce good results. Specific advantages, disadvantages and complications for each modality should be considered when deciding on which management strategy to employ for each specific patient, anatomical location, and defect size.

Effect of Health Care and Rehabilitation Nursing and Analysis of Neurovascular Preservation of Patients Undergoing Reconstruction of Severed Finger under X-ray Image Examination

OBJECTIVE

The study aimed to provide a guideline for continuous rehabilitation nursing for patients with severe finger replantation, and establish a satellite contact point for patients with severe finger replantation after discharge, so as to ensure scientific and effective rehabilitation training after discharge and explore the role of continuous rehabilitation nursing measurement in severe finger rehabilitation and neurovascular preservation.

METHODS

A total of 380 patients accepting neurovascular preservation finger replantation in the hand surgery department were divided into an observation group and a control group according to the number of hospitalizations. All patients underwent reconstructive surgery of severed finger. X-ray filming was used to monitor the postoperative nursing effect of neurovascular preservation of severed finger. The discharged patient information questionnaire was filled 3 days before the discharge. Then, a patient information database was established, and rehabilitation training was performed. Finally, sexual rehabilitation nursing follow-up intervention, telephone follow-up, and cross-referring intervention were carried out. Postoperative x-ray images were taken regularly to observe the recovery of reconstructed finger.

RESULTS

There was no difference in daily life ability scores and hand function scores between the 2 groups at discharge (P > 0.05). The daily life ability scores and hand function scores of the observation group were better than those of the control group at 1 and 6 months after discharge (P < 0.05), the difference is statistically significant. As the discharge time prolonged, the daily life ability score and hand function score of the 2 groups of patients gradually increased. X-ray images showed that the replanted finger body was well developed, phalanx was in good antithesis, and there was no epiphysis.

CONCLUSIONS

Continuous rehabilitation nursing measures should be taken after the replantation of the severed finger after neurovascular preservation, which provides standardized rehabilitation training standards for patients with replantation of severed finger after discharge, improves patient training compliance, promotes hand function recovery as soon as possible, and enables patients to return to society as soon as possible, which is worthy of clinical promotion and application.

Versatile design of compound vastus lateralis muscle and anterolateral thigh musculocutaneous perforator free flaps for customized reconstruction of complex skin and soft tissue defects in the extremities

BACKGROUND

Compound anterolateral thigh flaps are popular for three-dimensional reconstruction of complex soft tissue defects. We present our 10-year experience using compound vastus lateralis (VL) muscle and anterolateral thigh musculocutaneous perforator (ALTP) flaps, and introduce three versatile customizations of this flap for individualized reconstruction of complex three-dimensional soft tissue defects.

METHODS

From May 2008 to June 2017, compound VL muscle and ALTP flaps were performed in 67 consecutive patients aged 14-75 years (62 men and 5 women). The defects were in either the lower (n = 53) or upper extremity (n = 14), and ranged in size from 8 × 4 cm2 to 25 × 6 cm2. Dead space volume ranged from 4 × 2 × 1 cm3 to 20 × 3 × 2 cm3, and all flaps were harvested from patients' thighs as one of three types. In type A, a single perforator supplied both the skin and muscle components, with the vascular bundle penetrating the muscle component. In type B, a single perforator supplied both skin and muscle components with separate branches to the skin and muscle. In type C, separate vessels supplied the skin and muscle.

RESULTS

In the 67 patients, 65 flaps survived, and the donor site was closed directly. Vascular compromise occurred in four patients on the first postoperative day. Two flaps were salvaged after emergency re-exploration. Flap loss occurred in two patients, and these defects were repaired using other flaps. The follow-up period ranged from 8 to 60 months (mean, 11.9 months). All flaps had satisfactory appearance and texture, and no patients experienced limited hip and knee joint mobility from the donor site operation.

CONCLUSIONS

Compound VL muscle and ALTP flaps are a reliable option to reconstruct complex defects of the extremities. Identifying three flap types allowed for more precise customization to cover complex defects with limited donor site morbidity.
