Abstract Purpose Minimally invasive surgery using short stems in total hip arthroplasty gained more popularity. The differences in change of hip offset and implant positioning in minimally invasive approaches are not fully known. Therefore, this study was conducted to evaluate the difference in reconstruction of hip offset and implant positioning in direct anterior approach (DAA) and minimally invasive anterolateral approach (AL MIS). Methods A single surgeon series of 117 hips (117 patients; mean age 65.54 years ± 11.47; index surgery 2014–2018) were included and allocated into two groups: group A (DAA) with 70 hips and Group B (AL MIS) with 47 patients operated. In both groups the same type of cementless curved short hip stem and press fit cup was used. Results Both groups showed an equal statistically significant increase of femoral (p < 0.001) and decrease of acetabular offset (p < 0.001). Between both groups no statistically significant difference in offset reconstruction, leg length difference or implant positioning could be found. Leg length increased in both groups significantly and leg length discrepancy showed no difference (group A: − 0.06 mm; group B: 1.11 mm; p < 0.001). A comparable number of cups were positioned outside the target zone regarding cup anteversion. Conclusion The usage of a curved short stem shows an equal reconstruction of femoro-acetabular offset, leg length and implant positioning in both MIS approaches. The results of this study show comparable results to the existing literature regarding change of offset and restoration of leg length. Malposition of the acetabular component regarding anteversion poses a risk.

Abstract Background The quest for better patient outcomes is driving to the development of minimally invasive spine surgical techniques. There are several evidences on the use of microsurgical decompression surgery for degenerative lumbar spine stenosis; however, few of these studies compared their outcomes with the traditional laminectomy technique. Objectives The aim of our study was to compare outcomes following microsurgical decompression via unilateral laminotomy for bilateral decompression (ULBD) of the spinal canal to the standard open laminectomy for cases with lumbar spinal stenosis. Subjects and methods Cases were divided in two groups. Group (A) cases were operated by conventional full laminectomy; Group (B) cases were operated by (ULBD) technique. Results from both groups were compared regarding duration of surgery, blood loss, perioperative complication, and postoperative outcome and patient satisfaction. Results There was no statistically significant difference between both groups regarding the improvement of visual pain analogue, while improvement of neurogenic claudication outcome score was significant in group (B) than group (A). Seventy-three percent of group (A) cases and 80% of group (B) stated that surgery met their expectations and were satisfied from the outcome. Conclusion Comparing ULBD with traditional laminectomy showed the efficacy of the minimally invasive technique in obtaining good surgical outcome and patient satisfaction. There was no statistically significant difference between both groups regarding the occurrence of complications The ULBD technique was found to respect the posterior spinal integrity and musculature, accompanied with less blood loss, shorter hospital stays, and shorter recovery periods than the open laminectomy technique.

Background: Percutaneous, transverse distal metatarsal osteotomy with K-wire fixation (the Bösch technique) is an established technique for hallux valgus correction. Nevertheless, the risk of damaging the anatomical structures during the operation is unknown. Methods: Forty fresh-frozen anatomical foot specimens with hallux valgus deformity underwent a percutaneous corrective procedure. Specimens of group A (n = 20) were operated by an experienced surgeon while specimens of group B (n = 20) were done by untrained residents. Results: The dorsal cutaneous nerve was injured in 1 of 20 cases in group A and 6 of 20 cases in group B ( P = .037). There was a significant difference in overall complication rate between specimens of group A and group B ( P = .043). Conclusions: The results show an increased risk of perioperative injury of the dorsal cutaneous branch of the deep peroneal nerve as well as a significant effect of the surgeon’s experience on the overall complication rate. Clinical Relevance: Results of this study are highly relevant for all surgeons who perform percutaneous, minimally invasive hallux valgus surgery to avoid damage to the peripheral nerves. In addition, the data suggest an intensive training for surgeons before minimally invasive hallux valgus surgery is performed without supervision.

Objective: To observe the ultrasonographic characteristics of conjoined tendon repair in direct anterior approach for total hip arthroplasty (DAA-THA), and to evaluate the efficacy of musculoskeletal ultrasound in determining the healing after joint tendon repair. Methods: A total of 60 patients who required primary total hip arthroplasty in Yulin Orthopedic Hospital of Chinese and Western Medicine from July 2020 to July 2021 were selected; the patients were divided into two groups, an observation group, group A (n = 30), and a control group, group B (n = 30), according to different intraoperative methods. There was no significant difference in gender, age, and diagnosis between the two groups. Direct anterior approach was used for both the groups. For group A, the joint capsule and conjoined tendon (superior gemellus, obturator internus, and inferior gemellus) were repaired in situ, whereas for group B, only the joint capsule was repaired in situ, while the conjoined tendon was not repaired. The healing of the tendon was observed. Results: (1) in terms of diagnosis, after conjoined tendon repair, 26 cases in group A showed good tendon continuity, good tension, and a small amount of effusion echo around, three cases showed partial interruption of tendon echo, low echo, or no echo inside with insufficient structural clarity, and a case showed complete interruption; in group B, all 30 cases had continuous interruption, poor tension, tendon retraction, and thickening; the healing rate of group A’s conjoined tendon repair was 96.67%; (2) in terms of prognostic assessment, one month after the surgery, the Harris score of group A was significantly higher than that of group B (P < 0.05); however, there was no significant difference in the terms of the Harris score between the two groups 3-6 months after surgery (P > 0.05); the effective tension of conjoined tendon and the effective muscle strength of group A were significantly higher than those of group B (P < 0.05). Conclusion: Musculoskeletal ultrasound has high diagnostic value in the healing of conjoined tendon and provides dynamic clinical observation after conjoined tendon repair in DAA-THA; it is proven that DAA-THA with conjoined tendon repair on the premise of reconstructing the joint capsule can well restore its tension, enhance its muscle strength, significantly improve early joint stability and joint function, as well as facilitate the rapid recovery of patients.

Abstract Background The direct anterior approach for total hip arthroplasty (THA) has specific advantages, but injury to the tensor fasciae lata muscle (TFLM) remains a concern. This injury in part negates some of the advantages of the intermuscular approach, because injury of the muscle fibers of the TFLM can lead to less satisfactory clinical results. Thus, in this study, we propose an intraoperative method to protect the TFLM and demonstrate its feasibility.Methods Fifty-six patients undergoing THA by the direct anterior approach were divided randomly into two groups. In group A, the TFLM was protected by an autogenous tissue “pad” created from the anterior capsule of the joint that was rotated to protect the TFLM from direct contact with the retractors needed to expose the joint space. In group B, the operation was carried out in the typical fashion with no other protection of the TFLM except the attempt by the surgeons to consciously avoid compressive injury of the TFLM. We evaluated the magnitude of changes in the muscle cross-sectional area (MSCA) and fatty atrophy (FA) early and postoperatively between groups by magnetic resonance imaging. The differences in blood hemoglobin and serum levels of myoglobin, lactate dehydrogenase (LDH), and creatine phosphokinase (CPK) were compared at 8, 24, and 48 h, postoperatively. Postoperative drainage volume and pain evaluated by visual analogue scores (VAS) were compared between the two groups.Results LDH, CPK and myoglobin in group B were significantly higher than those in group A at 8, 24, and 48 hours after the surgery. (p<0.05) Compared to the group A, the decrease of hemoglobin in group B displayed significantly at 24 and 48 hours after surgery. (P<0.05) The significantly increased MSCA and FA of TFLM were demonstrated in group B. The PDV and VAS in group B were significantly higher compared with those in group A. (P<0.05)Conclusions Using the anterior capsule of the hip joint as an autogenous, protective capsular tissue pad to limit the trauma to the TFLM during a direct anterior approach to THA is an effective method to protect the TFLM and improve the clinical effect.

Abstract Background Total hip arthroplasty (THA) via the direct anterior approach (DAA) using dual mobility cup (DMC) is considered to effectively prevent postoperative dislocation. However, the dislocation and reduction procedure using a trial implant during the surgery is difficult because of high soft tissue tension. Thereby, leg length discrepancy (LLD) is difficult to assess when using DM via the DAA. Purpose To compare the LLD between cases using conventional SM and those using DMC in THA via the DAA with fluoroscopy. Patients and methods We retrospectively investigated 34 hips treated with DMC (DMC-DAA group) and 31 hips treated with SM (SM-DAA group). The LLD was defined as the difference in the distance from the teardrop to the medial-most point of the lesser trochanter between the operative and nonoperative sides at immediate postoperative X-ray. Results The mean LLD in the DMC-DAA group and SM-DAA group was 0.68 ± 7.7 mm and 0.80 ± 5.5, respectively, with no significant difference. The absolute value of the LLD in the DMC-DAA group and SM-DAA group was 6.3 ± 4.4 mm and 5.9 ± 5.5, respectively, with no significant difference. Conclusion Despite the difficulty in assessment of the LLD during THA via the DAA using DMC, this technique does not increase the LLD compared with the use of SM. Level of evidence III, matched case-control study.

Abstract Background: The optimal surgical approach in treating lumbar brucellosis (LBS) has not been determined. This study aims to compare the surgical efficacy of anterior approach and combined posterior and anterior approach in treating LBS.Method: A retrospectively cohort study included LBS patients undergoing lumber surgery in the Department of Orthopedics, Department of Orthopedics, Hebei Province from June 2012 to June 2016. According surgical approach, patients were divided into two groups; patients with one-stage anterior approach were classified into group A, and the rest of patients with combined posterior and anterior approach were group B. The operative time, intraoperative blood loss and, hospitalization stay were recorded to compare the surgical risk of two groups. In terms of treatment efficacy, visual analogue scale (VAS), bone graft fusion, erythrocyte sedimentation rate (ESR) and Oswestry disability index (ODI) were assessed and compared before and after surgery.Results: Eight-nine patients with LBS were included into the study. Fifty cases were males, and 39 patients were female. The mean age of this cohort was 61.9 ± 12 years, ranging from 23 to 78 years. Forty-nine patients were divided into group A, undergoing anterior debridement and bone graft fusion. Forty patients underwent posterior fixation combined with anterior approach (group B). The operation time of group A was 30 minutes shorter than that of group B. Group A had less intraoperative blood loss (800 vs. 900 ml; P <0.001). Hospital stay was four days shorter in group A. At the last follow-up, all patients were in good condition with ASIA Level E and ESR returned to normal. The bone fusion rate of Bridwell bone was 89.29% (45/49) and 80.00% (38/40) of group A and group B, respectively. In terms of surgical efficacy, there was no significant difference in VAS score between the two groups before and after operation (P > 0.05). Conclusions: One-stage anterior approach and combine posterior-anterior approach had no significant difference in terms of clinical efficacy. Individualized surgical treatment should be suggested in patients with complicated LBS and ineffective therapeutic treatment. Trial registration: This study has been retrospectively registered in local ethical Institution Review Board(No:[2020]068).
