Examining the precision and reliability of augmented reality (AR) for the localization of perforating vessels within the posterior tibial artery during the repair of soft tissue damage in the lower limbs using a posterior tibial artery perforator flap.
Ten patients undergoing ankle skin and soft tissue restoration benefited from the posterior tibial artery perforator flap's application between the months of June 2019 and June 2022. Among the group, there were 7 men and 3 women, with an average age of 537 years (average age range, 33-69 years). Five cases of injury were attributed to traffic accidents, while four involved bruising from heavy objects, and one was due to a machine malfunction. The extent of the wounds varied from a minimum of 5 cm by 3 cm up to a maximum of 14 cm by 7 cm. The elapsed time between the injury and subsequent operation exhibited a range from 7 to 24 days, averaging 128 days. The lower limbs were subjected to CT angiography prior to surgery, and the generated data enabled the reconstruction of three-dimensional models of perforating vessels and bones within Mimics software. The skin flap's design and resection were guided by the precise positioning provided by the augmented reality projection of the above images onto the surface of the affected limb. The flap's size fluctuated, demonstrating a range from 6 cm by 4 cm up to 15 cm by 8 cm. The donor site was either directly sutured or restored with a skin graft.
Augmented reality (AR) technology facilitated the preoperative localization of the 1-4 perforator branches of the posterior tibial artery (mean 34 perforator branches) in a cohort of 10 patients. Surgical observations of perforator vessel placement were largely in agreement with the preoperative AR projections. The interval between the two points in space extended from 0 to 16 millimeters, resulting in a mean distance of 122 millimeters. The flap was successfully and precisely harvested and repaired, replicating the preoperative design. The nine flaps escaped the perils of vascular crisis without incident. Two patients manifested local skin graft infections. A single patient additionally exhibited flap distal edge necrosis, resolving after a dressing change. Chinese steamed bread Subsequent skin grafts survived, and the incisions healed in a manner conforming to first intention. Patients were monitored for 6-12 months, yielding an average follow-up time of 103 months. The flap maintained its softness, with no discernible scar hyperplasia or contracture present. At the conclusion of the follow-up period, the American Orthopaedic Foot and Ankle Society (AOFAS) score demonstrated excellent ankle function in eight patients, good function in one patient, and poor function in one patient.
The preoperative assessment of posterior tibial artery perforator flap locations using augmented reality (AR) technology can minimize the risk of flap necrosis, and the surgical procedure is straightforward.
AR technology facilitates preoperative planning for posterior tibial artery perforator flaps by precisely locating perforator vessels. This leads to a reduced risk of flap necrosis, and a more straightforward operative technique.

The combination techniques and optimization strategies applied during the harvest process for anterolateral thigh chimeric perforator myocutaneous flaps are reviewed and summarized.
Between June 2015 and December 2021, a retrospective study examined clinical data from 359 individuals admitted with oral cancer. Thirty-three eight males and twenty-one females, with an average age of three hundred fifty-seven years, ranged in age from twenty-eight to fifty-nine years. 161 cases of tongue cancer were reported, adding to 132 cases of gingival cancer and 66 cases of buccal and oral cancer. UICC TNM staging statistics indicated 137 cases associated with T-stage tumors.

The illness's course lasted between one and twelve months, having a mean of sixty-three months. After the radical resection, remaining soft tissue defects, ranging from 50 cm by 40 cm to 100 cm by 75 cm, were repaired using free anterolateral thigh chimeric perforator myocutaneous flaps. The myocutaneous flap's collection was largely categorized into four procedural steps. bacterial co-infections The perforator vessels, originating primarily from the oblique and lateral branches of the descending branch, were exposed and separated in step one. Step two of the procedure focused on isolating the main perforator vessel's pedicle and determining the muscle flap's vascular pedicle's origin, which could be traced to the oblique branch, the lateral descending branch, or the medial descending branch. The third step in the process identifies the source of the muscle flap, encompassing both the lateral thigh muscle and rectus femoris. Step four involved the specification of the muscle flap's harvest method, based on the muscle branch type, the distal part of the main trunk, and the lateral aspect of the main trunk.
The surgical team successfully harvested 359 free anterolateral thigh chimeric perforator myocutaneous flaps. Every examination revealed the presence of anterolateral femoral perforator vessels. In a cohort of 127 cases, the perforator vascular pedicle of the flap was sourced from the oblique branch, whereas in 232 cases, it was derived from the lateral branch of the descending branch. In 94 instances, the vascular pedicle of the muscle flap emanated from the oblique branch; in 187 cases, it arose from the lateral branch of the descending branch; and in 78 cases, it stemmed from the medial branch of the descending branch. Muscle flaps were harvested from the lateral thigh muscle in 308 cases and from the rectus femoris muscle in 51 cases. Cases of harvested muscle flaps included 154 examples of the muscle branch type, 78 examples of the distal main trunk type, and 127 examples of the lateral main trunk type. In terms of size, skin flaps displayed a range from 60 cm by 40 cm to 160 cm by 80 cm, while muscle flaps exhibited a range from 50 cm by 40 cm to 90 cm by 60 cm. In 316 instances, the perforating artery was found to anastomose with the superior thyroid artery, while the accompanying vein likewise anastomosed with the superior thyroid vein. The perforating artery, in 43 cases, was found to be anastomosed with the facial artery; correspondingly, the accompanying vein was likewise anastomosed with the facial vein. Six patients presented with hematomas following the surgical intervention, and four showed signs of vascular crisis. Among the cases reviewed, seven were successfully salvaged after emergency exploration. One case presented with partial skin flap necrosis, responding favorably to conservative dressing management, and two cases displayed complete necrosis, requiring repair via a pectoralis major myocutaneous flap procedure. A follow-up of 10 to 56 months (mean 22.5 months) was conducted on all patients. A pleasing presentation was afforded by the flap, and both swallowing and language functions returned to normal. The donor site exhibited only a linear scar, and no noticeable impairment to the thigh's function resulted. TAPI-1 The follow-up of patients revealed a local tumor recurrence in 23 cases and cervical lymph node metastasis in 16 cases. A staggering 382 percent three-year survival rate was observed, translating to 137 patients surviving out of the original 359.
Categorizing the critical points within the anterolateral thigh chimeric perforator myocutaneous flap harvest in a clear and adaptable manner can substantially optimize the surgical protocol, enhance operational safety, and lessen the difficulty of the procedure.
An optimized surgical protocol for anterolateral thigh chimeric perforator myocutaneous flap harvests is achievable through the deployment of a transparent and adaptable classification system of critical points, thereby enhancing safety and simplifying the procedure.

The imaging analysis indicated ossification situated on the left in four instances, on the right in three, and on both sides in four patients. Among the prevalent clinical symptoms, chest and back pain or lower limb pain consistently presented together with lower limb numbness and pronounced fatigue. The disease's progression lasted between 2 and 28 months, with a median duration of 17 months observed. Data on the duration of the operation, the length of the patient's stay in the hospital following the procedure, and any postoperative complications were documented. The visual analogue scale (VAS) quantified chest, back, and lower limb pain, while the Oswestry Disability Index (ODI) and Japanese Orthopaedic Association (JOA) score assessed functional recovery preoperatively and at 3 days, 1 month, 3 months, and final follow-up.
