目的:讨论侧后方减压融合术治疗胸腰椎骨折的优缺点及临床应用。方法:对12例胸腰椎骨折采用侧后方减压植骨融合术,经一个手术入路完成减压及脊椎的稳定重建。 结果:12例病例随访13～36个月,术后无一例神经症状加重;6例术后原有神经症状明显改善,2例2个月后神经症状开始恢复,3例无改善;12例均获得骨性融合。 结论:侧后方减压融合术是治疗胸腰椎骨折的较好方法。但其技术要求高,视野显露有限,操作范围较窄,易出血增加了手术难度。
Objective To summarize the cl inical effect of anterolateral thigh pedicle or free perforator flap in repairing soft tissue defect in the extremities. Methods From March 2000 to January 2009, 32 cases of soft tissue defect were treated with pedicle or free anterolateral thigh perforator flap. There were 30 males and 2 females with an median age of28 years (4-53 years). Soft tissue defects included left radial side in 3 cases, the left lateral elbow in 1 case, knee in 5 cases, calf in 14 cases, dorsal is pedis in 5 cases, and planta pedis in 4 cases. The defect area ranged from 9 cm × 6 cm to 15 cm × 13 cm. Nine cases compl icated by bone defect and 1 case by radial nerve defect. The time from injury to hospital ization was 1 hourto 4 months (mean 5 days). Defects in 27 cases were repaired by anterolateral thigh perforator flap, simultaneously combined with transplantation with the second toe in 1 case, with sural nerve using arterial ized small saphenous vein in 1 case, nd with fibular or il ium in 4 cases. Defects in other 5 cases were repaired with flaps pedicled with superior lateral genicular artery. Neuroanastomosis was performed in 14 cases of the flaps. The size of the flaps ranged from 10 cm × 8 cm to 16 cm × 15 cm. Skin defects at donor site were repaired with spl it thickness skin graft or sutured directly. Results All patients were followed up from 8 months to 9 years with an average of 18 months. The flaps survived well and the wounds healed by first intention in 29 cases, 3 flaps necrosed and cured after symptomatic management. Skin graft at donor site survived completely in 9 cases. The color and texture and thickness of the flaps were similar to those of recipient site. After 6 months, the sensation of the flaps recovered to grade S3-4 in 14 patients whose cutaneous nerve were anastomosed, partial recovery was observed in other patients. In 4 patients receiving transplantation of fibular or il ium, the bony heal ing was achieved within 4 to 6 months. No obvious dysfunction was found at the donor site. Conclusion The pedicle anterolateral thigh perforator flap is long and thick with constant location. Anastomosis or transferring is easy to perform. It can provide big area and feel ing recovery by nerve anastomosis. It is an effective method to repair soft tissue defect of the extremities.
ObjectiveTo evaluate the specific application and effect of balance point fixation technique in arthroscopic fixation of avulsion fracture of anterior cruciate ligament.MethodsThe data of 65 patients with anterior cruciate ligament avulsion fracture treated by arthroscopy in Department of Orthopaedics, Panzhihua Central Hospital between June 2012 and June 2018 were analyzed retrospectively. According to whether the balance point fixation technique was used or not, the patients were divided into routine operation group (group A, n=22) and balance point fixation group (group B, n=43). The operation time, Visual Analogue Scale (VAS) pain score, length of hospital stay, intraoperative bone re-fracture rate, incidences of limb swelling and deep venous thrombosis, Lysholm score and knee joint stability of the two groups were analyzed. Chi-square test or Fisher’s exact test was used for nominal data. Independent samples t-test or paired samples t-test was used for measurement data. Rank sum test was used for ordinal data. Repeated measures analysis of variance was used for repeated measurement data. Two-sided statistical significance level was set at α=0.05.ResultsThere was no statistically significant difference in age, sex composition, fracture type, combined injury, time from injury to operation, preoperative VAS score, or Lysholm score between the two groups (P>0.05). The incisions of all patients healed in the first stage without incision complications. After adjustment, the reduction of fracture in group A was basically satisfactory, 4 cases (18.2%) had re-fracture; 1 case (2.3%) in group B had re-fracture due to poor bone condition, and group B was better than group A in re-fracture incidence (P=0.041). The operation time and length of hospital stay in group B were shorter than those in group A [(90.27±34.27) vs. (49.67±10.44) min,P<0.001; (8.09±1.23) vs. (5.35±1.07) d, P<0.001], the postoperative VAS score in group B was lower than that in group A (4.23±0.87 vs. 2.60±0.62, P<0.001), the degree of pain relief in group B was better than that in group A (3.32±1.29 vs. 4.44±1.50, P=0.004), the incidence of postoperative limb swelling in group B was lower than that in group A (22.7% vs. 4.7%, P<0.05); the difference in incidence of postoperative deep venous thrombosis between the two groups was not statistically significant (P>0.05). All patients were followed up for more than one year, the fractures healed completely, and the postoperative VAS score and Lysholm score at one year after operation were significantly improved compared with those before operation, but there was no significant difference in the postoperative 6-month Lysholm score, stability evaluation, or postoperative 1-year Lysholm score between the two groups (P>0.05).ConclusionsThe balance point fixation technique plays a positive role in relieving postoperative pain, shortening operation time and average hospital stay, and reducing the incidence of complications by realizing the quantification of the best fixed point to reduce repeated operation and side injury. It can provide a technical reference for clinical work.
Objective To compare the effectiveness of proximal femoral nail antirotation (PFNA) and reconstruction nail with minimally invasive technique for ipsilateral femoral shaft and extracapsular hip fractures in young and middle-aged patients. Methods Sixty-nine young and middle-aged patients with ipsilateral femoral shaft and extracapsular hip fractures were treated between January 2000 and August 2010, and their data were analyzed retrospectively. Of them, fractures were fixed by reconstruction nail in 44 cases (reconstruction nail group) and by PFNA in 25 cases (PFNA group). There was no significant difference in gender, age, weight, injury cause, fracture type, or disease duration between 2 groups (P gt; 0.05). The operation time, blood loss, fracture healing time, complications, and functional outcomes were compared between 2 groups to evaluate the effectiveness. Results The operation time and blood loss in the PFNA group were significantly less than those in the reconstruction nail group (P lt; 0.05). The follow-up time was 12-38 months (mean, 20 months ) in the PFNA group and was 12-48 months (mean, 22 months) in the reconstruction nail group. No complication occurred as follows in 2 groups: wound infection, deep venous thrombosis, pulmonary embolism, breakage of the implants, avascular necrosis of the femoral head, or serious rotation and shortening deformity of lower limbs. In the PFNA group and the reconstruction nail group, 1 patient underwent technical difficulty in nail implant and 7 patients underwent technical difficulty in proximal locking screw, respectively; 3 patients and 6 patients had intra-operative iatrogenic fracture of femoral shaft, respectively; and delayed union of femoral shaft was observed in 1 patient and 2 patients, respectively. The complication rate was 20% (5/25) in the PFNA group and 34% (15/44) in the reconstruction nail group, showing no significant difference (χ2=1.538, P=0.215). No significant difference was found in fracture healing time between 2 groups (P gt; 0.05). At last follow-up, there was no significant difference in Harris hip score and Evanich knee score between 2 groups (P gt; 0.05). Conclusion PFNA or reconstruction nail with minimally invasive technique is a good method to treat ipsilateral femoral shaft and extracapsular hip fractures, but the PFNA is superior to the reconstruction nail because of simple operation.
