To explore the application value of infrared thermography (IRT) technique assisted peroneal artery perforator flap in repairing oral and maxillofacial defects.

The clinical data of 20 patients with oral and maxillofacial malignant tumors treated with peroneal artery perforator flap between October 2020 and December 2021 were retrospectively analysed. There were 13 males and 7 females, with an average age of 56.5 years (range, 32-76 years). There were 8 cases of tongue cancer, 5 cases of parotid gland cancer, 4 cases of buccal cancer, and 3 cases of mandibular gingival cancer; and 12 cases of squamous cell carcinoma, 3 cases of adenoid cystic carcinoma, and 5 cases of mucoepidermoid carcinoma. Color Doppler ultrasound (CDU) and IRT technique were performed before operation to locate the peroneal artery perforator and assist in the design of the flap. The sensitivity, specificity, positive predictive value, and negative predictive value of CDU and IRT technique were compared with the actual exploration durillofacial defects has a high clinical application value.

To summarize and analyze the characteristics and treatment strategies of post-traumatic lower limb deformity based on QIN Sihe Orthopaedic Surgery Database.

A clinical data of 837 patients with post-traumatic lower limb deformities treated by orthopaedic surgery between May 25, 1978 and December 31, 2020 in QIN Sihe Orthopaedic Surgery Database were analyzed retrospectively. The information of the patient's gender, age at the time of surgery, region of origin, cause of trauma, deformity side, orthopedic surgery related information (operation time, location, type, and fixation method after operation) were summarized and analyzed.

All patients came from 32 provinces, municipalities, autonomous regions, and Taiwan in China. Among them, 551 cases (65.83%) were male and 286 cases (34.17%) were female. The age of the patients at the time of surgery was 3-84 years old, with an average of 27.6 years old, and the most patients were 16-45 years old (559 cases, 66.78%). The main cause of trauma was traffic accidenue) is the main methods for correction and functional reconstruction of post-traumatic lower limb deformity.
Post-traumatic lower extremity deformity patients have a large proportion of males, with a wide geographical distribution, involving various parts of the lower extremities, and most commonly in the foot and ankle. Orthopedic surgery combined with bone external fixation (Ilizarov technique) is the main methods for correction and functional reconstruction of post-traumatic lower limb deformity.
To analyze the similarities and differences of bone microstructure and apoptosis phenotype of lateral column, middle column, and medial column in type L2 and L3 osteonecrosis of the femoral head (ONFH) specimens classified by China-Japan Friendship Hospital (CJFH) classification, so as to carry out a quantitative study of ONFH "three-columns structure theory" and to provide research support for the treatment of ONFH by rotational osteotomy through the base of femoral neck.

Discarded femoral head specimens from 16 patients (16 hips) with CJFH type L2 and L3 ONFH undergone total hip arthroplasty between April 2020 and February 2021 were selected as the research objects. First, the "three-column structure" of the femoral head was three-dimensionally segmented by Micro-CT, and the bone volume to total volume (BV/TV), bone surface area to bone volume ratio (BS/BV), trabecular spacing/separation (Tb.Sp), trabecular thickness (Tb.Th), and trabecular number (Tb.N) in the lateral column, middle column, and medial significant difference in the bone parameters between the three columns of the CJFH type L3 ONFH femoral head (
>0.05). There was no significant difference in the rate of empty lacunae between the three columns of the CJFH type L2 and L3 ONFH femoral head (
>0.05). Immunohistochemical staining showed that a large number of tissue sections were detached, and only a small amount of non-specific staining was found in the sections without detachment, so the positive cell rate could not be calculated.

The middle and medial columns of the CJFH type L2 ONFH has better trabecular structures than the lateral column, and there is no significant difference in trabecular structures among the three columns of the CJFH type L3 ONFH.

To explore the biomechanical stability of the medial column reconstructed with the exo-cortical placement of humeral calcar screw by three-dimensional finite element analysis.

A 70-year-old female volunteer was selected for CT scan of the proximal humerus, and a wedge osteotomy was performed 5 mm medially inferior to the humeral head to form a three-dimensional finite element model of a 5 mm defect in the medial cortex. Then, the proximal humeral locking plate (PHILOS) was placed. Cu-CPT22 According to distribution of 2 calcar screws, the study were divided into 3 groups group A, in which 2 calcar screws were inserted into the lower quadrant of the humeral head in the normal direction for supporting the humeral head; group B, in which 1 calcar screw was inserted outside the cortex below the humeral head, and the other was inserted into the humeral head in the normal direction; group C, in which 2 calcar screws were inserted outside the cortex below the humeral head. The models were loaded with axial, shear, and ro humeral fractures with comminuted medial cortex, exo-cortical placement of 1 or 2 humeral calcar screw of the locking plate outside the inferior cortex of the humeral head can also effectively reconstruct medial column stability, providing an alternative approach for clinical practice.
To compare the short-term effectiveness of repairing distal tibiofibular syndesmosis with metal screws and absorbable screws.

A retrospective analysis was performed on the clinical data of 63 patients with ankle fracture combined with injury of the distal tibiofibular syndesmosis admitted between January 2017 and January 2020. Among them, 31 patients were treated with absorbable screw fixation of the distal tibiofibular syndesmosis (research group) and 32 patients were treated with metal screw fixation of the distal tibiofibular syndesmosis (control group). There was no significant difference in gender, age, cause of injury, surgical side, time from injury to operation, fracture type, preoperative visual analogue scale (VAS) score, and American Orthopaedic Foot & Ankle Society (AOFAS) score between the two groups (
>0.05). The operation time and fracture healing time were recorded and compared between the two groups. X-ray film was taken to evaluate the effect of ankle joint reduction and fixatio no significant difference in effectiveness between absorbable screws and metal screws, and there is no need for secondary operation to remove screws.
To investigate the effectiveness difference between bone transport with a locking plate (BTLP) and conventional bone transport with Ilizarov/Orthofix fixators in treatment of tibial defect.

The clinical data of 60 patients with tibial fractures who met the selection criteria between January 2016 and September 2020 were retrospectively analyzed, and patients were treated with BTLP (BTLP group,
=20), Ilizarov fixator (Ilizarov group,
=23), or Orthofix fixator (Orthofix group,
=17) for bone transport. There was no significant difference in gender, age, cause of injury, time from injury to admission, length of bone defect, tibial fracture typing, and comorbidities between groups (
>0.05). The osteotomy time, the retention time of external fixator, the external fixation index, and the occurrence of postoperative complications were recorded and compared between groups. The bone healing and functional recovery were evaluated by the Association for the Study and Application of the Method of Ilizarov (Agroup, and 12 cases (70%) in the Orthofix group. The incidence of complication in the BTLP group was significantly lower than that in other groups (
<0.05).

BTLP is safe and effective in the treatment of tibial defects. BTLP has apparent advantages over the conventional bone transport technique in osteotomy time, external fixation index, and lower limb functional recovery.

To investigate the effectiveness of tunnel osteogenesis technique combined with locking plate in the treatment of aseptic non-hypertrophic nonunion of femoral shaft.

The clinical data of 23 cases of aseptic non-hypertrophic nonunion of femoral shaft treated with tunnel osteogenesis technique combined with locking plate between January 2017 and December 2020 were retrospectively analysed. There were 17 males and 6 females with an average age of 41.4 years (range, 22-72 years). There were 22 cases of closed fracture and 1 case of open fracture. The types of internal fixation at admission included intramedullary nail in 14 cases and steel plate in 9 cases. The number of nonunion operations received in the past was 0 to 1; the duration of nonunion was 6-60 months, with an average of 20.1 months. Among them, there were 17 cases of aseptic atrophic nonunion of the femoral shaft and 6 cases of dystrophic nonunion. Twenty-two cases were fixed with 90° double plates and 1 case with lateral single plate. The operatunction and quality of patients' life.
Tunnel osteogenesis technique combined with locking plate in the treatment of aseptic non-hypertrophic nonunion of femoral shaft has a high healing rate and fewer complications, which can effectively relieve pain and improve lower limb function and quality of patients' life.
To investigate the effectiveness of high tibial osteotomy (HTO) combined with arthroscopic surgery to treat medial compartment knee osteoarthritis (KOA) and secondary arthroscopic exploration to evaluate the outcome of cartilage and meniscus.

A clinical data of 57 patients with medial compartment KOA with varus deformity of lower extremities admitted between August 2014 and October 2018 were retrospectively analyzed. There were 23 males and 34 females with an average age of 51.2 years (range, 41-63 years). The disease duration ranged from 2 to 8 years, with an average of 4.7 years. The preoperative femorotibial angle was (179.86±4.69)°, the relative position of the lower limb mechanical axis passing through the tibial plateau was 24.21%±6.98%, and the posterior slope of the tibial plateau was (5.23±1.45)°. The Kellgren-Lawrence grade of knee joint was grade Ⅱ in 22 cases and grade Ⅲ in 35 cases.
