RESUMO

PURPOSE: Split abdominal wall muscle flap (SAWMF) is a technique to repair large defects in congenital diaphragmatic hernia (CDH). A possible objection to this intervention could be any associated abdominal muscle weakness. Our aim is to analyze the evolution of this abdominal muscle wall weakness. METHODS: Retrospective review of CDH repair by SAWMF (internal oblique muscle and transverse) from 2004 to 2023 focusing on the evolution of muscle wall weakness. RESULTS: Eighteen neonates of 148 CDH patients (12,1%) were repaired using SAWMF. Mean gestational age and birth weight were 35.7 ± 3.5 weeks and 2587 ± 816 g. Mean lung-to-head ratio was 1.49 ± 0.28 and 78% liver-up. Seven patients (38%) were prenatally treated by tracheal occlusion. Ninety-four percent of the flaps were used for primary repair and one to repair a recurrence. One patient (5.6%) experienced recurrence. Abdominal muscle wall weakness was present in the form of a bulge. Resolution of weakness at 1, 2 and 3 years was 67%, 89% and 94%, respectively. No patient required treatment for weakness or died. CONCLUSIONS: Abdominal muscular weakness after a split abdominal wall muscle flap repair is not a limitation for its realization since it is asymptomatic and presents a prompt spontaneous resolution. LEVEL OF EVIDENCE: IV.

RESUMO

BACKGROUND: Chronic compression of the inferior trunk of the brachial plexus can result in severe pain and progressive atrophy and weakness of the musculature of the forearm and hand, known as Gilliatt-Sumner hand (GSH). The objective of treatment for these patients is to stop further atrophy and pain. Restoration of motor function has been thought to be seldom achieved. The aim of the present contemporary case series was to describe the diagnosis, treatment, and outcomes of surgery for GSH. METHODS: All patients referred between January 2017 and May 2021 with visible signs of a GSH were included. Visible GSH signs were defined as muscle atrophy of the abductor digiti minimi, abductor pollicis brevis, and/or interosseous musculature. All the patients had undergone additional electrodiagnostic (ED) assessments and high-resolution ultrasound (HRUS) studies. All the patients with a diagnosis of GSH had undergone thoracic outlet decompression (TOD) surgery using a transaxillary or supraclavicular approach. The outcomes were measured using the thoracic outlet syndrome disability scale, cervical brachial symptom questionnaire, and disability of the arm, shoulder, and hand scale scores and patient-reported outcomes of motor function, measured using a numerical rating scale (NRS). The standardized elevated arm stress test (sEAST) was used to assess the patients' motor function before and after TOD surgery. RESULTS: A total of 20 patients had been referred to our center with visible signs of a GSH. The clinical examination showed atrophy of the abductor digiti minimi, abductor pollicis brevis, and interosseous musculature in all 20 patients. The ED assessments showed plexopathy of the lower brachial plexus in all the patients. HRUS showed an indented inferior trunk of the brachial plexus (so-called wedge-sickle sign) in 18 patients (90%). Of the 20 patients, 17 had undergone TOD surgery (15 transaxillary TOD and 2 supraclavicular TOD). Three patients had refrained from surgery. The median follow-up interval was 15.0 months (interquartile range, 14.0 months). The thoracic outlet syndrome disability scale score had improved significantly (preoperatively: mean, 6.31; 95% confidence interval [CI], 5.49-7.13; postoperatively: mean, 4.25; 95% CI, 2.80-5.70; P = .026). The same improvement was seen for the cervical brachial symptom questionnaire scores (preoperatively: mean, 77.75; 95% CI, 66.63-88.87; postoperatively: mean, 42.65; 95% CI, 24.77-60.77; P = .001) and disability of the arm, shoulder, and hand scale scores (preoperatively: mean, 59.13; 95% CI, 51.49-66.77; postoperatively: mean, 40.96; 95% CI, 24.41-57.51; P = .032). The NRS score for muscle weakness and sEAST score showed no statistically significant differences before and after TOD for the whole group (mean preoperative NRS score for muscle weakness, 6.22; 95% CI, 4.31-8.14; mean postoperative NRS score for muscle weakness, 5.11; 95% CI, 3.25-6.97; P = .269). However, four patients (23.52%) had reported a ≥50% decrease in the NRS score for muscle weakness and a minimum increase of 20% in the total and average force using the sEAST. The NRS for numbness showed a statistically significant decrease for the whole group (preoperatively: mean, 5.67; 95% CI, 4.18-7.16; postoperatively: mean, 3.33; 95% CI, 1.37-5.29; P = .029). CONCLUSIONS: A combination of physical examination, ED assessments, and HRUS studies can differentiate GSH in the differential diagnosis. HRUS appears to have an advantage over ED studies in confirming GSH by visualization of compression of the brachial plexus. TOD surgery will stop the progressive muscle atrophy and significantly reduce neurogenic thoracic outlet syndrome complaints, and, in some patients, motor function will recover.

RESUMO

BACKGROUND: Most of the previous studies about the surgical treatment of dropped head syndrome (DHS) are small case series, and their primary outcome measures were cervical alignment parameters. Therefore, little is known about the associations between pre- and postoperative global sagittal alignment in the whole spine and the clinical outcomes of the surgical treatment of DHS. In this study, we investigated the surgical outcomes of DHS, including correction of cervical and global spinal sagittal alignment. METHODS: This study was a retrospective observational study. Fifteen patients with DHS who had undergone correction surgery were enrolled. Surgical outcomes, including complications and implant failures, were investigated. We assessed cervical alignment parameters as well as spinopelvic global alignment parameters, including pelvic incidence (PI), lumbar lordosis (LL), and C7-sacral sagittal vertical axis (SVA). We examined the changes in these parameters using pre- and posoperative whole spine lateral radiographs. The parameters were compared between the failure and nonfailure groups. RESULTS: Recurrence of sagittal imbalance and horizontal gaze difficulty was observed in 6 cases (40%). In all, 3 cases (20%) exhibited a distal junctional failure and required multiple surgeries with extension of fusion. Of all the radiographic parameters compared between the failure and nonfailure groups, significant differences were only observed in pre and postoperative SVA and PI-LL. CONCLUSIONS: Our results suggest that the global sagittal alignment parameters, including PI-LL and SVA, were different between the patients with failure and non failure, and these parameters might have notable impacts on surgical outcomes. Surgeons should consider PI-LL and SVA while determining the surgical course for patients with DHS.

RESUMO

BACKGROUND: Correcting pseudoparalysis of the shoulder due to massive rotator cuff tear is challenging. The most reliable treatment for restoring active shoulder elevation is debatable. Therefore, the purpose of this systematic review was to evaluate the success of various treatment options for reversing pseudoparalysis due to massive rotator cuff tear. METHODS: A search was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines of the MEDLINE database, Cochrane database, Sportdiscus, and Google Scholar database for articles evaluating shoulder pseudoparalysis due to massive rotator cuff tears. RESULTS: Nine articles evaluating reverse total shoulder arthroplasty (RTSA), superior capsular reconstruction (SCR), and rehabilitation programs were included in the study. Though there was variability, the definition of pseudoparalysis was active forward elevation (AFE) less than 90° with preserved passive range of motion (ROM). Reversal of pseudoparalysis was defined as restoration of AFE greater than 90°. The overall rate of reversal of pseudoparalysis across studies was similar for RTSA (96% ± 17%) and SCR (94% ± 3%). However, there was a difference in average improvement in AFE for RTSA (56° ± 11°) and SCR (106° ± 20°). A progressive rehabilitation program described improvements in a single study with 82% reversal of pseudoparalysis. CONCLUSION: The available Level IV evidence suggests that RTSA and SCR reliably reverse pseudoparalysis in most patients with massive, irreparable rotator cuff tears. However, the dissimilar improvements in ROM suggest that a more consistent definition of pseudoparalysis is warranted. Future randomized controlled trials are needed to determine the best treatment approach for patients with massive irreparable rotator cuff tears.

RESUMO

PURPOSE: Dropped head syndrome (DHS) is a rare clinical entity which is defined as a chin-on-chest deformity in the standing or sitting position, resulting from sagittal imbalance of the cervical region. The purpose of the present study was to clarify the radiologic features of DHS in the overall sagittal alignment of the spine. We also investigated the changes in sagittal alignment after correction surgery for DHS. METHODS: Twenty DHS patients [1 male and 19 female, with an average age of 78.9 years (range 59-88)] with a main complaint of horizontal gaze disorder were enrolled in this study. Spino-pelvic lateral radiographs in the free-standing clavicle position were taken of all patients. Parameters such as sagittal vertical axis (SVA), C2-7 angle, clivo-axial angle (CAA), C2-7 SVA, T1 slope, thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT) were measured, and the radiologic features of DHS in the overall sagittal alignment of the spino-pelvis were investigated. Eight patients underwent correction surgery, and the parameter changes between pre- and post-operative radiographs were also examined. RESULTS: DHS appeared to have two distinct types: SVA+ and SVA-. Seven of 20 cases were SVA+, and 13 were SVA-. The radiologic parameters in which we found statistically significant differences between the groups were: 80.2 ± 68 and -44.5 ± 40 (SVA), 42.1 ± 16.8 and 18.4 ± 11.4 (T1 slope), and 21.1 ± 19.2 and 44.2 ± 19.8 (LL) in SVA+ and SVA-, respectively. After surgical intervention, T1 slope and LL appeared to approach normal in the SVA- group, because compensation at downward spine was no longer necessary. In SVA+ group, although the patients gained horizontal gaze after surgery, abnormality of the sagittal alignment in the whole spine remained, because compensation in the thoracic and lumbar spine was still insufficient. CONCLUSIONS: The present study has indicated that radiologic feature of DHS in the sagittal alignment of the overall spino-pelvis can be categorized into two types: SVA+ and SVA-.

RESUMO

Cervical spondylotic amyotrophy is characterized by severe, proximal upper extremity weakness including an inability to abduct the shoulder and flex the elbow. Treatment using both medical and surgical decompression approaches has produced variable results. This paper reports the use of nerve transfers (spinal accessory to suprascapular, flexor carpi ulnaris fascicle of ulnar to biceps motor branch, radial nerve branch to triceps to axillary) to restore shoulder and elbow function in a case of unilateral cervical spondylotic amyotrophy involving C5 and C6 myotomes. Evidence of regeneration was observed on electromyography as well as clinically at 5 months postoperatively. At 3 years after surgery, recovery of elbow flexion and shoulder abduction was Medical Research Council grade 4/5 with improved external rotation and considerably improved patient-rated Disabilities of the Arm, Shoulder and Hand scores. We propose that nerve transfers be considered along with other reconstruction modalities in the treatment of cervical spondylotic amyotrophy.

RESUMO

PURPOSE: This prospective study analyzes clinical characteristics and outcomes of sacral extradural spinal meningeal cysts (SESMC) without spinal nerve root fibers (SNRF) undergoing neck transfixion. METHODS: Using the relationship between the cysts and SNRF, SESMCs were divided into two types: cysts with SNRF known as Tarlov cysts and cysts without. If the SESMCs were identified as those without SNRFs, the neck of the cyst was transfixed, ligated and the remaining cyst wall removed distal to the clip. The improved Japanese Orthopedic Association (IJOA) scoring system was used to evaluate preoperative and postoperative neurological functions of the patients. RESULTS: Twenty-seven patients were included in this study. The average age was 42.7 ± 11.93 years. The mean preoperative IJOA score was 17.5 ± 2.47, and postoperative IJOA score was 19.1 ± 1.41. The difference between preoperative and postoperative IJOA scores was statistically significant (t = -3.75, P = 0.001), with a significant improvement in neurological function after surgery. Among the improvements in neurological function, the most significant was bowel/bladder function (z = -2.33, P = 0.02). CONCLUSION: Most patients experienced significant improvement in their neurological function after surgery. The most significant area of neurological improvement was bowel/bladder dysfunction, however, preoperative stool or urine incontinence did not recover completely.

RESUMO

BACKGROUND: Polio infection can often lead to orthopedic complications such as arthritis, osteoporosis, muscle weakness, skeletal deformation, and chronic instability of the joints. The purpose of this study was to assess the outcomes and associated complications of arthroplasty in shoulders with sequelae of poliomyelitis. METHODS: Seven patients (average age, 70 years) were treated between 1976 and 2013 with shoulder arthroplasty for the sequelae of polio. One patient underwent reverse shoulder arthroplasty, 2 had a hemiarthroplasty, and 4 had total shoulder arthroplasty. Average follow-up was 87 months. Outcome measures included pain, range of motion, and postoperative modified Neer ratings. RESULTS: Overall pain scores improved from 5 to 1.6 points (on a 5-point scale) after shoulder arthroplasty. Six shoulders had no or mild pain at latest follow-up, and 6 shoulders rated the result as much better or better. Mean shoulder elevation improved from 72° to 129°, and external rotation improved from 11° to 56°. Average strength in elevation decreased from 3.9 to 3.4 postoperatively, and external rotation strength decreased from 3.9 to 3.3. This, however, did not reach significance. Evidence of muscle imbalance with radiographic instability was found in 4 shoulders that demonstrated superior subluxation, anterior subluxation, or both. This remained asymptomatic. No shoulder required revision or reoperation. CONCLUSIONS: Shoulder arthroplasty provides significant pain relief and improved motion in patients with sequelae of poliomyelitis. Muscle weakness may be responsible for postoperative instability, and careful selection of the patient with good upper extremity muscles must be made.

RESUMO

This article evaluates the "Bobby Pin" procedure in the correction of myogenic ptosis accompanying extraocular muscle weakness. We retrospectively reviewed 26 eyelids of 13 patients who underwent "Bobby Pin" procedure for myogenic ptosis accompanying extraocular muscle weakness. We evaluated the patients' clinical features such as age, etiology of ptosis, symptoms, standard ptosis measurements, associated systemic diseases, additional ophthalmic conditions, complications, and recurrence. Etiology of myogenic ptosis and extraocular muscle weakness was oculopharyngeal dystrophy in 4 (31%) patients, chronic progressive external ophthalmoplegia in 4 (31%) patients, myotonic dystrophy in 2 (23%) patients, and idiopathic in 3 (15%) patients. The mean levator function was approximately 5 mm pre- and post-operatively (range 1 to 12 mm). The mean margin-to-reflex distance 1 increased from -1.1 mm (below the light reflex) pre-operatively to +0.4 mm (above the light reflex) post-operatively. After a mean follow-up of 40 months, only 1 (8%) patient experienced ptosis recurrence. Upper eyelids were symmetric in both contour and height in all patients. Mild superficial keratopathy involving less than 10% of cornea was observed in 4 (31%) patients. The "Bobby Pin" procedure is an effective and long-lasting treatment option for correcting acquired ptosis accompanying extraocular muscle weakness. The procedure is safe, simple, easily learned, time- and cost-effective, and does not require any expensive equipment.

RESUMO

INTRODUCTION: The natural history of motor deficit due to lumbar disc herniation has been thought to be favourable. However, on closer analysis of seminal articles on this topic, this is not the case for patients with severe motor deficits (MRC grade ≤3). The aim of this study is to answer the following questions: (1) Is surgical intervention beneficial in patients with severe motor weakness (defined by MRC grade of 3 or less) due to herniated lumbar nucleus pulposus? (2) Does time to surgery from onset of motor weakness influence the outcome? (3) Are there any other prognostic factors? MATERIALS AND METHODS: A comprehensive search was conducted in MEDLINE and EMBASE from 1970 upto July 2013. Inclusion criteria for studies are: (1) minimum of three patients aged 18 and older, who had symptomatic herniated lumbar disc prolapse and underwent surgery, (2) description of pre and post-operative muscle weakness utilising the Medical Research Council (MRC) muscle power grade or equivalent, such that both reviewers could confidently identify a cohort of patients with at least grade three motor weakness or worse, (3) a minimum of 6 months follow-up. RESULTS: Seven studies were identified with a total of 354 patients. Complete recovery was seen in 38.4% of patients following surgery and 32% following non-operative treatment. Age and grade of motor deficit were identified as significant prognostic factors in some of the studies. CONCLUSION: The current available evidence is not robust enough to address the questions posed. We have proposed a framework for future studies.

RESUMO

Subjects with total knee arthroplasty (TKA) exhibit decreased quadriceps and hamstring strength. This may bring about greater relative effort or compensatory strategies to reduce knee joint moments in daily activities. To study gait and map out the resource capacity, knee muscle strength was assessed by maximal voluntary concentric contractions, and whole body kinematics and root mean square (RMS) electromyography (EMG) of vastus lateralis and semitendinosus were recorded during stair ascent in 23 unilateral TKA-subjects ~19 months post-operation, and in 23 healthy controls. Muscle strength and gait velocity were lower in the TKA group, but no significant group differences were found in RMS EMG or forward trunk lean. The results suggest that reduced walking velocity sufficiently compensated for reduced knee muscle strength.

RESUMO

CASE: An 8-year-old girl with a history of acute flaccid paralysis presented with chronic valgus drop foot causing tripping and falling. Traditionally surgical correction of this deformity is accomplished by transferring the posterior tibialis tendon to enhance dorsiflexion. The authors describe a new technique which transfers the peroneus longus tendon to the dorsum of the foot in a patient with weakness of the posterior tibialis muscle. The patient's drop foot and gait were improved at the 22-month follow-up. CONCLUSION: Successful transfer of the peroneus longus was accomplished with improved limb clearance during gait and coronal alignment in stance.

RESUMO

BACKGROUND: Cervical spondylotic amyotrophy (CSA), characterized by amyotrophy and muscular weakness of the upper limbs, is caused by damage to anterior spinal root or anterior horn of the spinal cord. Formerly, anterior decompression and fusion were performed for treatment of CSA, but it has recently been reported that posterior decompression is also effective. However, a consensus on the choice of procedure has not yet been reached. Selective laminoplasty as minimally invasive surgery is a posterior decompression procedure that alleviates axial neck pain. Because, for CSA patients, the responsible lesion level is localized, this procedure combined with foraminotomy enables simultaneous spinal cord and root decompression. Therefore, we report the results of this treatment for CSA. METHODS: Subjects were 28 patients (25 males, 3 females), average age 50.6 years and average follow-up 43.5 months. The muscles involved were deltoid for 14 patients, biceps for 11, and extensor digitorum communis and/or intrinsic muscles of the hand for 9. MMT scores were grade 2 for 23 cases and grade 3 for 5 cases. To evaluate the results of minimally invasive surgery, cervical ROM (C2-7) and postoperative neck pain (VAS) on the first postoperative day and 1 week after surgery were evaluated. RESULTS: Muscle strength improvement was rated as "excellent" for 18 patients, "good" for 9, and "fair" for 1, with none rated "poor". Four of 10 patients whose muscle strength did not fully improve had distal type CSA and/or had preoperative MMT scores of 2. Average %ROM was 91.2 % and almost complete cervical ROM was maintained. The average postoperative VAS score was 2.6 on the first postoperative day and 1.2 1 week after surgery. CONCLUSIONS: Selective laminoplasty with segmental decompression is advantageous for minimizing postoperative neck pain and for simultaneous decompression of the affected spinal cord segment and nerve root.

RESUMO

BACKGROUND: Mesenteric panniculitis is a rare chronic fibrosing inflammatory disease that typically affects the adipose tissue and mesentery of the small intestine but may also affect the mesosigmoid and the mesocolon. The pathology of this disease remains unclear despite association with some malignancies or inflammatory disorders. We report a case of mesocolic panniculitis and a literature review of its clinical presentation, imaging findings, associated conditions and treatment options. CASE PRESENTATION: A 64 year-old Caucasian man was admitted to the gastroenterology department for severe weakness, left lower quadrant abdominal pain, weight loss and diarrhoea. Physical examination revealed a palpable firm mass occupying the entire left part of the abdomen. Abdominal CT-scan showed fatty infiltration of the mesosigmoid and left mesocolic fat which was strongly suggestive of panniculitis. Laparoscopic surgery revealed an inflamed and edematous mesocolon and mesosigmoid; the sigmoid mucosa appeared petechial which was suggestive of venous ischemia. Histological examination of surgical biopsies revealed mesocolic panniculitis. Despite exhaustive investigation, no associated conditions were found and the cause was classified as idiopathic. Surprisingly, the patient clinically improved without therapeutic intervention other than supportive care. CONCLUSION: Although mesenteric panniculitis is most often a radiographic diagnosis without clinical symptomatology, it can also present with significant general status alteration. We report a case of mesocolic panniculitis complicated by development of an inflammatory mass associated with ischemic colitis. Mesenteric panniculitis is a difficult diagnosis to make which typically requires histologic confirmation. The overall prognosis is good with supportive treatment.

RESUMO

Most patients experience pain relief and functional improvement following arthroscopic rotator cuff repair, but some continue to experience symptoms postoperatively. Patients with so-called failed rotator cuff syndrome, that is, with continued pain, weakness, and limited active range of motion following arthroscopic rotator cuff repair, present a diagnostic and therapeutic challenge. A thorough patient history, physical examination, and imaging studies (eg, plain radiography, MRI, magnetic resonance arthrography, ultrasonography) are required for diagnosis. Management is determined based on patient age, functional demands, rotator cuff competence, and the presence or absence of glenohumeral arthritis. Treatment options include revision repair, nonanatomic repair with or without biologic or synthetic augmentation, tendon transfer, and arthroplasty.

RESUMO

BACKGROUND: Previous studies of minimal medial epicondylectomy for cubital tunnel syndrome included patients with mild disease, making it difficult to determine how much this procedure improved sensory and motor impairments in patients with moderate to severe disease. QUESTIONS/PURPOSES: We asked if minimal epicondylectomy improved sensory and motor impairments in patients with moderate to severe cubital tunnel syndrome. METHODS: We retrospectively reviewed 25 patients treated with minimal medial epicondylectomy for advanced cubital tunnel syndrome involving motor weakness between January 2003 and February 2009. Preoperatively, five patients had Medical Research Council (MRC) Grade 4 motor strength without atrophy (McGowan Grade IIA), nine had MRC Grade 3 motor strength with detectable atrophy (McGowan Grade IIB), and 11 had MRC Grade 3 or less motor strength with severe atrophy (McGowan Grade III). Postoperatively we obtained DASH scores and evaluated improvement of sensory impairment and motor impairment: excellent with minimal sensory deficit and motor deficit, good with mild deficits, fair with improved but persistent deficit(s), and poor with no improvement. The minimum followup was 13 months (mean, 46 months; range, 13-86 months). RESULTS: The mean DASH score was 14 points (range, 2-47 points). Of the 25 patients, sensory improvement and motor improvement were excellent in 16 patients, good in five, fair in two, and poor in two. Twenty-three of the 25 patients improved at least one McGowan grade. There were no complications, such as medial elbow instability. CONCLUSIONS: Minimal medial epicondylectomy can improve sensory and motor impairments for patients with moderate to severe cubital tunnel syndrome. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the guidelines for authors for a complete description of levels of evidence.

RESUMO

Reestablishing anterior rectus fascial integrity remains a clinical challenge after transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction. The main concerns include herniation and bulging due to abdominal weakness. Mesh-assisted closure of the fascial defect has improved bulging and herniation rates but infection, extrusion, and encapsulation are serious concerns with mesh use. Biologic tissue matrices may overcome some of these mesh-related complications. The initial experience of using Strattice for fascial closure after TRAM flap procedure is described in this article. Strattice was in-lain and sutured between the anterior and posterior layers of the rectus fascia, at the rectus muscle donor site. The abdominal wall was closed with progressive tension sutures. Postoperative complications at the donor site were assessed. A total of 16 unilateral and 9 bilateral reconstructions were performed in 25 patients. Length of hospital stay was 2 to 3 days which is shorter than with mesh repair (typically 4-5 days). During a mean follow-up period of 14.0 months, complications occurred in 7 patients (28%): seroma formation (2), minor skin separation (2), superficial skin infection (2), and superficial wound dehiscence (1). Complications were not directly related to Strattice and all, except one (superficial skin infection), were resolved without surgical intervention. In all patients, routine abdominal functions were restored 4 months postoperatively. Strattice is a safe, alternative option to synthetic mesh for fascial repair following TRAM flap breast reconstruction. When used in conjunction with progressive tension suture closure of the abdominal wall, dynamic reconstruction of the abdominal wall with resumption of abdominal function is possible with Strattice.

RESUMO

Scarring or detachment of the hip abductors, particularly of the gluteus medius, from their insertion may lead to severe abductor weakness, recurrent dislocations, pain, and diminished quality of life. We performed a retrospective study to evaluate whether vastus lateralis shift is associated with satisfactory results and low rate of complications. Eleven adults underwent vastus lateralis shift to bridge a well-documented abductor muscles' insertion defect. Preoperative and postoperative hip functions were assessed applying the Merle d'Aubigne score, British Medical Council scale, and Visual Analog Scale. Significant postoperative improvement was noted in mean Merle d'Aubigne score, gluteus medius muscle force, and quality of life. Vastus lateralis shift represents a viable treatment option for hip abductor deficiency, significantly improving abductor strength and overall quality of life.

RESUMO

CASE: A 68-year-old woman suffered from an irradiation-induced dropped head syndrome (DHS). Fusion surgery was vehemently rejected by the patient. A new surgical method, avoiding fusion, was invented and performed to treat her DHS. This novel surgical technique of "occipitopexy"-a ligamentous fixation of the occiput to the upper thoracic spine-is described in detail. One year postoperatively, the patient was very satisfied, able to maintain a horizontal gaze, and rotate her head 20° to each side. CONCLUSION: This is the first report describing "occipitopexy" as an alternative to cervicothoracic fusion for patients with flexible DHS.
