Changes in spino-pelvic alignment after surgical treatment of high-grade isthmic spondylolisthesis by a posterior approach: a report of 41 cases

Purpose

To analyze changes in spino-pelvic parameters (SPPs) after surgery of high-grade lumbar isthmic spondylolisthesis (HDIS).

Methods

We analyzed 41 patients affected by HDIS operated upon by attempt of reduction and posterior spinal fusion with pedicle screw systems with or without interbody fusion. Pelvic tilt (PT), lumbar lordosis (LL), pelvic incidence (PI), and sacral slope (SS) were measured, and patients were further divided into balanced and unbalanced pelvis subgroups.

Results

SS passed from 46.8° ± 9.8° preoperatively to 50.1° ± 10.1° (p = 0.02). PT passed from 26.7° ± 6.7° preoperatively to 22.9° ± 7.5° (p = 0.003). Unbalanced patients showed significantly higher PT and lower SS compared to the balanced patients preoperatively, and these corrected after surgery. Patients with instrumentation failure (n = 5) had significant increase in PT values postoperatively (p = 0.018).

Conclusions

We confirmed the positive effect of surgery on the SPPs in patients affected by HDIS, which showed different patterns of corrections with surgery for balanced and unbalanced pelvis patients.

     

The carpal tunnel syndrome in children

Introduction

Carpal tunnel syndrome (CTS) in children represents a complex challenge for the hand surgeon because of its rarity, poor patient cooperation, frequently associated malformation syndromes and mental retard, atypical symptoms and nuanced and poor sensitivity of instrumental tests. The most frequently associated causes with the CTS in children are rare congenital malformations and diseases, requiring an overall assessment of the young patient and a high degree of suspicion for the potentially associated canalicular syndrome. On the other hand, the associated syndromes may be the main ally for a diagnosis that starts from the knowledge of the literature and the surgeon's suspicion by observing the child wailing. Early diagnosis and decompression treatment is mandatory.

Materials and methods

The authors report a case series of 26 children and analyze the etiology and diagnostic algorithms. Patient assessment was based on complete clinical examination and medical history collection of these young patients with the involvement of the family and educators.

Results

In all 26 patients treated, along an average period of 23 months (minimum 12, maximum 30), no signs of recurrence or persistence of median nerve disturbances were recorded.

Conclusions

In conclusion, we believe that anamnesis, a careful physical examination and analysis of instrumental examinations, should be accompanied by a thorough knowledge of rare diseases in the context of congenital malformations. The carpal tunnel syndrome, while well known and treated by each orthopedic surgeon, reveals a mysterious aspect in the context of the "fabulous" world of childhood illnesses, even more difficult than rare congenital diseases.

Fixation of winged scapula in facioscapulohumeral muscular dystrophy

Objective: To verify if stabilizing the scapulothoracic joint without arthrodesis could lead to functional improvement of shoulder range of motion and clinical improvement of winged scapula, we incorporated four additional patients into our previous analysis to determine if the results obtained were long lasting, and to compare this fixation with the other techniques described in the literature, balancing the benefits with the complications.Design: A retrospective study.Participants: Thirteen patients with bilateral winged scapula affected by facioscapulohumeral muscular dystrophy. Nine of these patients had been analyzed in our previous study.Methods: Patients were operated on by bilateral fixing of the scapula to the rib cage using metal wires without arthrodesis (scapulopexy).Results: All patients experienced improvement in active range of motion of the shoulder and all of them had clinical improvement with complete resolution of the winged scapula. In all twenty-six surgical interventions of scapulopexy, a stable and long-lasting fixation of the scapula to the rib cage was achieved.The complications strictly associated to the surgical technique encountered were one pneumothorax, which was resolved spontaneously, and one wire breakage without trauma. Average follow-up was 10 years (range, 3 to 18 years).Conclusion: The scapulopexy used in this extended series of patients consisted of repositioning the scapula and fixing it to four ribs by using metal wires without performing arthrodesis.This technique has a low rate of complications, is reproducible, safe and effective, resulting in clinical and functional improvement.

A minimally invasive technique for surgical treatment of hallux valgus: simple, effective, rapid, inexpensive (SERI)

Purpose

Several bony and soft tissue procedures have been described for the treatment of hallux valgus, and currently mini-invasive surgical techniques are preferred in order to reduce surgical trauma, complications, time of surgery and to allow an earlier recovery. The aim of this study is to analyse a series of 1,000 consecutive cases of hallux valgus, surgically treated by the minimally invasive SERI technique, reporting results at mid-term follow-up.

Methods

We prospectively studied 641 patients (1,000 feet) with symptomatic hallux valgus surgically treated by SERI osteotomy. Inclusion criteria were: age between 20 and 65 years, reducible mild or moderate hallux valgus, HVA ≤ 40°, IMA ≤ 20°, and arthritis of the first metatarsophalangeal joint up to grade 2 according to the Regnauld classification.

Results

The American Orthopaedic Foot and Ankle Society (AOFAS) score rose from 46.8 ± 16.7 preoperatively to 89 ± 10.3 at last follow-up. Radiographic control at follow-up showed a complete healing of the osteotomy and remodelling of the metatarsal bone. Low rate of complication has been reported.

Conclusions

This study demonstrated that the SERI technique is effective in treating mild to moderate hallux valgus in terms of relief from symptoms and functional improvement. This technique allowed correction of the main parameters of the deformity, with durable clinical and radiographic results at a mid-term follow-up.

Cervical disc herniation and cervical spondylosis surgically treated by Cloward procedure: a 10-year-minimum follow-up study

Background  

Cervical degenerative pathology produces pain and disability, and if conservative treatment fails, surgery is indicated. The aim of this study was to determined whether anterior decompression and interbody fusion according to Cloward is effective for treating segmental cervical degenerative pathology and whether the results are durable after a 10-year-minimum follow-up.     

Surgical treatment of complex tibial plateau fractures by closed reduction and external fixation. A review of 32 consecutive cases operated

Abstract Complex tibial plateau fractures are a challenge in trauma surgery. In these fractures it is necessary to anatomically reduce the articular part of the fracture and to obtain stable fixation. The aim of this study is to review the results of a surgical technique consisting of fluoroscopic closed reduction and combined percutaneous internal and external fixation. Thirty-two complex tibial plateau fractures in 32 patients were included. Twenty-one fractures were closed, 4 were open Gustilo grade I, 3 were Gustilo grade II and 4 were Gustilo grade III. The mean age was 37.8 years (range 21–64 years). Surgery was performed with patients in transcalcaneal traction and the knee flexed at 30° was used. Through a 1-cm incision centred over the tibial metaphysis of the tibia, a 3.2-mm hole was drilled in the antero-medial tibial aspect. The tibial plateau fracture fragments were elevated using either 1 or 2 curved Kirschner wires under fluoroscopy to control the reduction. Then the fragments were fixed with 2 cannulated AO screws inserted through small incisions into the medial aspect of the tibial plateau. Knee rehabilitation started postoperatively. Weight bearing started after 8–12 weeks depending upon the radiographic appearance. All external fixators were removed in outpatient facilities. All patients were clinically and radiographically evaluated at a mean follow-up of 48 months (range 38–57 months). Clinical results were evaluated according to the Knee Society clinical score. Average healing time was 24 weeks (range 18–29 weeks). In 1 patient a non-union occurred. This patient was treated with open reduction and plate fixation. In 2 patients a varus knee deformity occurred and a surgical correction was performed. There were no surgical complications. Mean knee range of motion was 105° (range 75–125°) and mean Knee Society clinical score was 89. Twenty-five results were scored as excellent, 4 good, 2 fair and 1 poor. Using this technique there is limited soft tissue damage and virtually no periosteum damage to the fracture fragments. However anatomical reconstruction of the joint can be obtained. Furthermore knee rehabilitation can be started immediately after surgery. We think that these factors were responsible for the optimal clinical long-term results.     

Surgical treatment of symptomatic degenerative lumbar spondylolisthesis by decompression and instrumented fusion

Degenerative spondylolisthesis is characterized by the slippage of one vertebral body over the one below, with association of intervertebral disc degeneration and degenerative arthritis of the facet joints, which cause spinal stenosis. The aim of this study was to evaluate the clinical and radiographic results of 22 patients with symptomatic degenerative spondylolisthesis, operated on by decompressive laminectomy and instrumented posterolateral fusion associated with interbody fusion (PLIF). Mean age at surgery was 64 years (range, 57–72). Clinical results were evaluated on a questionnaire at the last follow-up visit concerning postoperative low back and leg pain, restriction of daily life activities, and resumption of sports activity. Lumbar spine radiographs were used to evaluate the status of fixation devices, the reduction of the spondylolisthesis, the lumbar sagittal balance and the presence of spinal fusion. No intraoperative or postoperative complications were encountered. There were no superficial or deep infections, fixation device loosening, or hardware removal. Mean follow-up time was 4 years (range, 3–6 years). Clinical outcome was excellent or good in 19 patients and fair in 3 patients. Preoperatively, mean forward vertebral slipping on neutral lateral radiographs was 5 mm, while postoperatively it decreased to 3 mm. Preoperatively, mean sagittal motion was 3 mm and angular motion was 8°, while postoperatively these values decreased to 1 mm and 1°, respectively. This study demonstrated that spinal decompression followed by transpedicular instrumentation associated with PLIF technique is a valid surgical option for the treatment of degenerative spondylolisthesis with symptomatic spinal stenosis. Clinical outcome, intended as relief of pain and resumption of activity, was improved significantly and fusion rate was high.
