OBJECTIVE: To compare the effectiveness of arthroscopic outside-in release for gluteal muscle contracture (GMC) in supine position versus lateral decubitus position. METHODS: The clinical data of 34 GMC patients meeting selection criteria between January 2022 and May 2023 were retrospectively analyzed. Arthroscopic contracture band release was performed in the lateral decubitus position (lateral group, n=14) or the supine position (supine group, n=20). No significant difference ( P>0.05) was observed between groups in baseline data, including gender, age, body mass index, preoperative GMC functional quantitative score, modified Harris hip score (mHHS), visual analogue scale (VAS) pain score, and hip flexion/adduction range of motion (ROM). The total operation time, release procedure time, non-release procedure time, intraoperative blood loss, hospital stay, and postoperative complications were recorded and compared. Functional outcomes (GMC functional quantitative score, mHHS score, VAS score, hip flexion/adduction ROM) were evaluated preoperatively and at 3, 12, and 24 months postoperatively. RESULTS: All incisions healed by first intention without major vascular or neurological complications. In the lateral group, 3 patients developed patchy bruising on bilateral buttocks and posterior thighs at 3 days after operation, which resolved after 2 weeks of ice packs and ultrasonic therapy. The supine group demonstrated significantly shorter total operation time, non-release procedure time, hospital stay, and reduced intraoperative blood loss versus the lateral group ( P<0.05). No significant difference was found in release procedure time ( P>0.05). All patients were followed up 24 months. Both groups showed significant improvements ( P<0.05) in mHHS score, GMC functional quantitative score, VAS score, and hip adduction/flexion ROM at all postoperative timepoints compared to preoperative values, with no significant intergroup differences ( P>0.05). CONCLUSION Both surgical positions effectively improve hip function in GMC patients. However, the supine position offers significant advantages over the lateral decubitus position in operation time, anesthesia management, intraoperative blood loss control, and reduced hospital stay.

OBJECTIVE: To investigate the clinical effect of minimally invasive technique in the treatment of moderate and severe gluteal muscle contracture. METHODS: A retrospective study was conducted on 85 patients (170 sides) with bilateral gluteal muscle contracture admitted from January 2016 to December 2019. All patients were treated with minimally invasive release of tendon knife. There were 32 males and 53 females, ranging in age from 15 to 37 years old, with an average age of (22.3±6.3) years old. Operation time, intraoperative blood loss, incision length, first postoperative ambulation time, complication rate, recurrence rate, and Harris hip score (HHS) were analyzed and evaluated. RESULTS: The average follow-up time was (16.2±4.6) months, ranging from 12 to 30 months. The operation time ranged from 7 to 15 min, with an average of (10.2±3.1) min. Intraoperative blood loss ranged from 2 to 20 ml, with an average of (8.4±2.2) ml. The incision length ranged from 0.6 to 2.0 cm, with an average of (0.8±0.3) cm. The time to postoperative ambulation ranged from 12 to 28 h, with an average of (20.0±3.2) h. All patients achieved primary wound healing without sciatic nerve injury or recurrence. HHS hip function scores ranged from 90 to 98, with an average score of (96.2±1.4). Complications included intraoperative tendon blade tip fracture in two cases (removed under fluoroscopic guidance) and subcutaneous hematoma in three cases-two resolved with compression and one with open evacuation.. Twenty-nine patients exhibited transient swaying gait postoperatively, of which 24 patients returned to normal after 4 weeks and 5 patients returned to normal after 6 weeks. CONCLUSION Minimally invasive tendon blade release is a safe and effective technique for treating gluteal muscle contracture, offering minimal trauma, rapid recovery, and excellent cosmetic and functional outcomes. However, it exhibits a low risk of blade tip fracture and sciatic nerve injury, warranting experienced surgical handling.

On November 17, 2013, the Second Affiliated Hospital of Kunming Medical University admitted a 23-year-old male patient with a high-temperature steel bar penetration injury from scrotum to buttocks who was transferred from another hospital. Expanded debridement, suture, and drainage of the perineum, right thigh, and right hip were performed as soon as possible after admission. A sputum suction tube was used as the guide mark for expanded debridement during the operation to ensure the accuracy of the direction and scope of expanded debridement. The incision was treated with vacuum sealing drainage (VSD) and full drainage. On the 20^th day after the operation (the 25^th day after admission), the unhealed wound was transplanted with split-thickness skin graft from the right thigh, and the drainage of the operation area and dressing change were strengthened. On the 53^rd day after injury, the patient was discharged after complete wound healing. This case suggests that VSD after early debridement is an effective means to treat high-temperature steel bar penetration injuries.

OBJECTIVE: To explore the clinical efficacy of silver needle lumbar and sacral spine approach in treating gluteal muscle syndrome. METHODS: Eighty-seven patients with gluteal muscle syndrome treated with silver needles in the Department of Rehabilitation Medicine of our hospital from September 2017 to September 2019 were selected. Except for symptoms of waist and hip pain and discomfort, all selected patients were examined by CT or MRI to confirm pathological imaging changes such as inflammatory exudation of the gluteal muscle. The 87 patients with gluteal muscle syndrome were divided into 2 groups according to the digital table method, and 42 patients in the lumbosacral approach group, including 19 males and 23 females, aged (50.70±12.45) years old, and disease duration of (1.63±1.27) years;45 cases in the buttock approach group, including 20 males and 25 females, aged (52.80±12.18) years old, with a course of disease of (1.78±1.22) years. The lumbosacral approach group was treated with spinal L to S bilateral articular process joints and L transverse process acupuncture needles, and the buttock approach group was treated with the gluteus medulla wing starting point and femoral trochanter stop. The VAS scores, soft tissue tenderness thresholds, and hip abductor muscle strength of the affected group were measured before and 4 weeks after treatment in the two groups. The clinical efficacy was also evaluated 4 weeks after treatment. RESULTS: After 4 weeks, the VAS score of the lumbosacral approach group was 1.26±0.70, and the buttock approach group was 1.18±0.74, which were significantly lower than those before treatment, but there was no statistical difference between the groups (>0.05). The soft tissue tenderness threshold and ipsilateral hip abductor muscle strength were (5.51±0.70) kg and (10.34±2.19) kg in the lumbosacral approach group, and (4.78±1.05) kg, (9.33±1.42) kg in the buttock approach group. The results in the lumbosacral approach group was better than those in the buttock approach group(<0.05). The clinical efficacy of the lumbosacral approach group:16 cases got an excellent result, 20 good, 5 fair and 1 poor;in the buttock approach group, 13 excellent, 17 good, 12 fair and 3 poor. The clinical efficacy between the two groups had statistical difference (<0.05). CONCLUSION In the treatment of gluteus medius syndrome with silver needle, lumbosacral approach and buttock approach can effectively relieve the pain. Compared with the improvement of soft tissue tenderness threshold and hip abductor muscle strength, the upper lumbosacral approach is more prominent, and the overall clinical effect is more significant.

14 cm, and HOB >7.8 cm were 10.80 (95% confidence interval [CI], 1.57–74.94), 5.26 (95% CI, 1.06–26.19), and 10.50 (95% CI, 1.03–107.12), respectively. Areas under the curve (AUCs) for AFI, HOB, and parity were 0.66 (95% CI, 0.54–0.78), 0.74 (95% CI, 0.64–0.85), and 0.69 (95% CI, 0.62–0.76), respectively. HOB had the largest AUC, but there were no significant differences among the AUCs of other factors. The cut-off value of HOB was 6 cm.CONCLUSION: This study showed that the AUC of HOB was greater than that of parity and AFI, although it was not statistically significant. As HOB is a noninvasive and comprehensive marker to predict successful ECV, consideration of HOB would be helpful before conducting ECV. Further studies are needed.]]>

It is difficult to differentiate acute skin failure (ASF) from pressure ulcer (PU). ASF is defined as unavoidable injury resulting from hypoperfusion caused by severe dysfunction of another organ system. We describe a case of ASF mistaken as PU that resulted in a legal dispute. A 74-year-old male patient was admitted to our intensive care unit with sepsis due to bacterial pneumonia. Despite the use of air cushions and regular position changes, skin ulcerations occurred over his occiput, back, buttock, elbow, and ankle. After improvement in his general condition, he was transferred to the department of plastic and reconstructive surgery. Debridement was performed immediately, followed by conservative treatment (including a vacuum-assisted closure device) for 6 weeks. The buttock and occiput wounds were treated surgically. Despite complete healing, his caregivers sued the hospital for failing to prevent PU formation. ASF is a pressure-related injury resulting from hemodynamic instability due to organ system failure. Unlike PU, ASF may occur despite the implementation of all appropriate preventive measures. Furthermore, misdiagnosis of ASF as PU can lead to litigation. Therefore, it is critical for the proper diagnosis to be made quickly, and for physicians to explain that ASF occurs despite proper preventative treatment.

BACKGROUND: Buttock pain is common, and there are no fixed guidelines for its diagnosis and treatment. This study compared a selective nerve root block and a facet joint block for patients with degenerative spinal disease and buttock pain. METHODS: Patients with degenerative spinal disease who presented with buttock pain, received a selective nerve root block (group A) or a facet joint block (group B) from June 2017 to September 2017, and were able to be followed up for more than 3 months were prospectively enrolled. Clinical results were assessed using a visual analog scale for comparative analysis. RESULTS: One day after the procedure, an excellent response was found in 7% and 6% of groups A and B, respectively; a good response was found in 41% and 13% of groups A and B, respectively. Two weeks later, an excellent response was found in 11% and 4% of groups A and B, respectively; a good response was found in 41% and 20% of groups A and B, respectively. Six weeks later, an excellent response was found in 11% and 7% of groups A and B, respectively, and a good response was found in 41% and 20% of groups A and B, respectively. At the final follow-up, more than 47% and 46% of patients showed a good response in groups A and B, respectively. In group A, the visual analog scale score improved compared to the pre-procedure value of 5.01 to 2.74 on day 1, 2.51 at week 2, 2.38 at week 6, and 2.39 at week 12. In group B, the visual analog scale score improved compared to the preprocedure value of 5.24 to 3.94 on day 1, 3.99 at week 2, 3.24 at week 6, and 2.59 at week 12. On day 1 and at weeks 2 and 6, group A showed a significantly better outcome than group B (p < 0.05). CONCLUSIONS: The selective nerve root block showed superior results up to 6 weeks post-procedure. Considering that the selective nerve root block is effective for treating radiculopathy, the primary cause of buttock pain can be thought to be radiculopathy rather than degenerative changes of the facet joint.

BACKGROUND: The slide-swing skin flap is a combination of transposition and adjacent skin sliding and can be used to close large, round defects with a flap that is smaller than the primary defect to produce aesthetically good results. OBJECTIVE: To evaluate the efficacy and safety of the slide-swing skin flap for various surgical defects caused by skin tumor excisions. METHODS: This retrospective case series, which includes 33 Asian patients between the ages of 25 and 86 years, describes the slide-swing skin flap after primary excision for malignant or premalignant skin conditions. The outcomes were assessed 12 weeks after surgery using the patient and observer scar assessment scale (POSAS). RESULTS: Patients were 25 male and 8 female, and the causes of surgery were various malignant skin tumors including malignant melanoma, dermatofibrosarcoma protuberans, and malignant nodular hidradenoma. Tumors were on the lower limb in eleven patients, back in nine patients, chest in five patients, face in three patients, buttock in three patients and two patients had tumors in other locations. The mean defect size was 3.5×3.1±1.9×2.2 cm (range, 1.4×0.9~9.0×12.0 cm). The mean patient POSAS total score was 9.7±3.0 and mean patient overall opinion score was 1.8±0.7. The mean observer POSAS total score was 11.0±2.7 and mean observer overall opinion score was 1.9±0.5. All flaps survived and postoperative recoveries were uneventful. CONCLUSION: The slide-swing skin flap is highly versatile and can be used to cover various surgical defects, irrespective of size and location, with excellent functional and cosmetic results.

Segmental neurofibromatosis, a subtype of neurofibromatosis type 1, is characterized by neurofibromas and/or café-au-lait spots limited to an area or segment of the body. Checkerboard pattern is a rare type of cutaneous mosaic manifestation, characterized by squares or broad ribbons of affected skin with sharp demarcation at the midline. Herein, we report the case of a patient with bilateral segmental neurofibromatosis with lentiginosis showing a checkerboard pattern. Our patient had multiple hyperpigmented macules on her entire body in a checkerboard pattern since birth. Several café-au-lait patches were observed on the left buttock and right axilla. A neurofibroma was incidentally found beneath the café-au-lait patch by histological examination, which showed ill-defined spindle cells with elongated nuclei at the deep dermis that stained positive for S-100. Based on the clinical presentation and histopathologic results, the patient was diagnosed with bilateral segmental neurofibromatosis with lentiginosis showing a checkerboard pattern.
