RESUMEN
Objective:To introduce a surgical method and clinical effect of using Masquelet technique combined with skin graft to cover chronic refractory wounds in elderly patients.Methods:From September 2020 to September 2022, 20 elderly patients with wounds of bone or tendon exposure in lower limbs were treated in the Department of Wound Repair, the Second Affiliated Hospital of Wenzhou Medical University. Due to the age and poor general condition of the patients, flap transfer for wound coverage were not allowed. Masquelet technique was therefore applied in the treatment of chronic wounds of such patients. Sizes of wounds were found at 4.5 cm×3.0 cm to 15.0 cm×6.0 cm and all accompanied with tendon and bone exposure, after thorough debridement. Wounds were then sealed with antibiotic bone cement several times. After having induced formation of membrane in wounds, free mesh skin graft was used to cover the refractory wounds. The patients were entered in follow up regularly after surgery at outpatient service, and telephone or video reviews. The wound healing of patients and whether there were related complications in the skin donor area were observed. The number of operation times in the first stage was 1-4 with an average of 1.3 times ± 0.7 times. Lower Extremity Function Scale (LEFS) was used to evaluate the recovery of lower limb function.Results:All 20 wounds healed well. The follow-up time was 3-12 months, with an average of 7.6 months. The appearance and texture of the skin in the wounds area were satisfactory. The mean LEFS was 69.83 point ± 10.82 point.Conclusion:Using Masquelet technique combined with free skin grafting to treat refractory wounds in the elderly patients can achieve satisfactory clinical outcomes. It is a simple and reliable supplement to the wound repair, and can reduce the surgical risk.
RESUMEN
Objective To explore the clinical effect of phalangeal fractures with self-made mini external fixator. Methods From June, 2014 to June, 2017, 16 cases of phalangeal fracture were treated with self-made mini external fixator. In the followed-up periods, the regulating rechecks of X-ray and measurement of interpha-langeal joint activity were determined. The total active movement (TAM), numerical pain ranting scale (NPRS) and morning stiffness was used to estimate the fracture healing and the hand function recovery. Results Pain and ab-normal movement around fracture was found 6 weeks after the operation in 1 case, which had been healed by re-moving the external fixation, open reduction and internal fixation with kirschner wire. The other 15 cases were fol-lowed-up of 48-72 (average, 58) weeks. The fracture has healed. And there was no osteomyelitis, no breakage and loosening of steel needles. The clinical healing time of the fracture was 14 to 16 weeks, with an average of 15.5 weeks. According to the TAM, NPRS and morning stiffness, there was excellent in 11 cases, and good in 4 cases. Conclusion The self-made mini external fixator can maintain the stability after fracture reduction, provide the tension required for the healing of collateral ligament and joint capsule, and meet the need of early functional exer-cise. It is an ideal treatment option for phalangeal fractures.
