Object Monomelic amyotrophy (MMA) is a benign, self-limiting lower motor neuron disease. Optimal surgical strategies—discectomy decompression and fusion (DDF) or corpectomy decompression and fusion (CDF)—for patients with aggravated symptoms (within 6 months of presentation) are controversial, particularly in those who are ineligible for conventional treatment. These 2 methods of anterior cervical decompression and fusion for MMA in patients unwilling or unable to wear a conventional cervical collar long term were evaluated. Methods Anterior cervical decompression and fusion were performed in 48 male patients with MMA between September 2007 and September 2010. Patients were randomly treated with anterior cervical discectomy decompression with autologous iliac crest bone grafting and internal plate fixation (DDF group: 24 patients) or anterior cervical corpectomy, posterior longitudinal ligament resection, autologous iliac crest bone grafting, and internal plate fixation (CDF group: 24 patients). Subjective symptom assessments and electromyography (EMG) examinations were conducted both preoperatively and postoperatively. Results Subjective assessments and EMG studies (mean follow-up duration 25.9 months) indicated improvement in 64.6% and 60% of patients, respectively. No significant correlations between the effectiveness of surgery and age at symptom onset, preoperative symptom duration, or postoperative follow-up time were found. Conclusions The lack of a significant difference in effectiveness between DDF and CDF favors DDF as more clinically applicable because of its lower procedural risks. As a second-line alternative to cervical collar treatment, surgical anterior cervical decompression and fusion via DDF or CDF may prevent further deterioration and produce good short-term therapeutic effects in patients with MMA; however, cervical collar treatment is recommended for eligible patients because of its lower associated risks.

Talonavicular (TN) coalition is a rare pathological union of the talus and navicular bones. We report the case of a 7-year-old girl with a symptomatic TN coalition, who underwent operative management with a lateral column lengthening procedure using autologous iliac crest bone grafting. There are no complications to report and the graft was incorporated at an early stage. At 3 year follow-up the patient has remained pain-free since the operation and maintained alignment. To our knowledge, this is the first reported case of TN coalition treated with reconstructive surgery in a paediatric patient.

Background: The Latarjet is a successful procedure but can be associated with significant complications, including failure. Iliac crest bone grafting (ICBG) is one of the salvage options for such failure. Purpose: To analyze factors associated with failure or success to restore shoulder stability with ICBG after Latarjet failure. Study Design: Case series; Level of evidence, 4. Methods: Twenty consecutive patients with recurrence of instability after a Latarjet procedure underwent revision using ICBG. Sixteen patients (80%) with a mean age of 35.0 years (range, 25-55) could be personally reexamined clinically and radiographically (including computed tomography scan) after a mean follow-up of 4.5 years (range, 2-8). Twelve patients had redislocation and 4 had recurrent subluxation after the Latarjet. Results: Salvage ICBG failed in 7 patients because of recurrent dislocations, with 5 necessitating reoperations: 2 arthrodeses, 1 reverse total shoulder arthroplasty, 1 repeat ICBG, and 1 Hill-Sachs allograft reconstruction and Bankart repair. Factors associated with ICBG failure were multidirectional instability (n = 2), subscapularis insufficiency (n = 1), uncontrolled seizures (n = 1), static inferior glenohumeral subluxation (n = 1), total graft resorption (n = 1), and voluntary dislocation attributed to schizoaffective disorder (n = 1). The initial Latarjet graft was malpositioned (too medial) in 3 of these patients. In patients without recurrent instability (n = 9), reasons for Latarjet failure were graft related: 6 graft avulsions, 2 graft resorptions, and 1 medial graft malpositioning. The mean absolute Constant score (62 to 87 points, P = .012) and relative Constant score (66% to 91%, P = .012), pain (10 to 15 points, P < .001), and Subjective Shoulder Value (31% to 85%, P = .011) in the group with a successful procedure were significantly improved over the preoperative state, and the total Western Ontario Shoulder Instability Index averaged 64% at final follow-up. Except in 1 case of major resorption, mild graft resorption or none was observed in successful procedures. Axial and sagittal graft positioning was good in all 9 patients. Conclusions: Salvage ICBG for failed Latarjet procedures failed in 7 of 16 patients. It was successful in patients with clearly graft-related factors of the initial Latarjet procedure. However, patients with unclear instability symptoms, subscapularis insufficiency, inferior subluxation, uncontrolled seizures, or psychological disorders were poor candidates for salvage ICBG, underlining the importance of careful patient selection for the initial Latarjet procedure and for salvage ICBG.

Objectives: We identified the optimal approaches for treating the diverse tumor subtypes of petroclival meningioma (PM) by analyzing the clinical benefits of various surgical approaches adopted for each subtype.Methods: Tumors in 102 PM patients from a single center who underwent surgical treatment were classified as upper clivus (UC), cavernous sinus (CS), tentorium (TE), or petrous apex (PA) types based on the attachment site of the tumor base and the displacement of the trigeminal nerve. The therapeutic effects of different surgical approaches among the subtypes were evaluated according to the patient outcomes.Results: The subtemporal (33.33%), retrosigmoid (16.67%), and Kawase approaches (50%) were used for the UC type. Simpson I/II resection was achieved in 46.66% of patients with the Kawase approach. Significant differences were found between the other two approaches (P = 0.044) and in the follow-up Karnofsky performance scale (KPS) scores (P = 0.008). The subtemporal (60%) and Kawase approaches (40%) were used for the CS type; neither approach achieved Simpson I/II resection. The retrosigmoid (25.81%) and Kawase approaches (74.19%) were used for the TE type. The Simpson I/II resection rates of the two approaches were 55.55 and 86.95%, respectively, and a significant difference was observed between them (P = 0.039). The retrosigmoid (43.75%) and Kawase approaches (56.25%) were used for the PA type. The Simpson I/II resection rates of the two approaches were 31.25 and 50%, respectively. The resection degrees of the two approaches and the KPS scores at follow-up were significantly different (P = 0.034).Conclusion: The individual microsurgical approaches adopted for the various PM tumor subtypes can provide maximal safe resection and good KPS scores. The Kawase approach is more suitable for PM, especially for UC- and PA-type PM tumors.

OBJECTIVEBoth structural allograft and PEEK have been used for anterior cervical discectomy and fusion (ACDF). There are reports that PEEK has a higher pseudarthrosis rate than structural allograft. The authors compared pseudarthrosis, revision, subsidence, and loss of lordosis rates in patients with PEEK and structural allograft.METHODSThe authors performed a retrospective review of patients who were treated with ACDF at their hospital between 2005 and 2017. Inclusion criteria were adult patients with either PEEK or structural allograft, anterior plate fixation, and a minimum 2-year follow-up. Exclusion criteria were hybrid PEEK and allograft cases, additional posterior surgery, adjacent corpectomies, infection, tumor, stand-alone or integrated screw and cage devices, bone morphogenetic protein use, or lack of a minimum 2-year follow-up. Demographic variables, number of treated levels, interbody type (PEEK cage vs structural allograft), graft packing material, pseudarthrosis rates, revision surgery rates, subsidence, and cervical lordosis changes were collected. These data were analyzed by Pearson’s chi-square test (or Fisher’s exact test, according to the sample size and expected value) and Student t-test.RESULTSA total of 168 patients (264 levels total, mean follow-up time 39.5 ± 24.0 months) were analyzed. Sixty-one patients had PEEK, and 107 patients had structural allograft. Pseudarthrosis rates for 1-level fusions were 5.4% (PEEK) and 3.4% (allograft) (p > 0.05); 2-level fusions were 7.1% (PEEK) and 8.1% (allograft) (p > 0.05); and ≥ 3-level fusions were 10% (PEEK) and 11.1% (allograft) (p > 0.05). There was no statistical difference in the subsidence magnitude between PEEK and allograft in 1-, 2-, and ≥ 3-level ACDF (p > 0.05). Postoperative lordosis loss was not different between cohorts for 1- and 2-level surgeries.CONCLUSIONSIn 1- and 2-level ACDF with plating involving the same number of fusion levels, there was no statistically significant difference in the pseudarthrosis rate, revision surgery rate, subsidence, and lordosis loss between PEEK cages and structural allograft.

Abstract Background Although most cases of humeral shaft nonunion respond well to surgical intervention, surgeons still encounter patients with humeral shaft nonunion who have already undergone repeated surgeries for nonunion. This study retrospectively analyzed the efficacy of double locking compression plate (LCP) fixation in combination with autogenous iliac crest bone grafting for recalcitrant humeral shaft nonunion. Methods A consecutive series of patients with aseptic recalcitrant humeral shaft nonunion underwent surgical treatment between May 2010 and August 2017 in our institution. Standardized treatment included thorough debridement, double LCP and screw fixation, and autogenous iliac bone grafting. The injury type and the duration of nonunion were recorded for all patients. The main outcome measurements were the Constant and Murley scale for shoulder function, Mayo elbow performance index (MEPI) for elbow function, and visual analog scale (VAS) for pain. In addition, all complications were documented. Results The study cohort comprised six females and nine males with a mean age of 45.3 ± 13.1 years. Each patient had already undergone at least one failed surgery for humeral shaft nonunion. The average duration of nonunion before the index intervention was 126.8 ± 124.2 months. All patients achieved bone union without implant failure. At final follow-up, the mean Constant and Murley score and mean MEPI were significantly improved, and the mean VAS score was significantly decreased. Each patient was very satisfied with the treatment. Four patients had complications, including one with a superficial wound infection, one with radial nerve palsy, one with ulnar nerve palsy, and one with discomfort at the iliac crest. Conclusion Double plate fixation combined with autogenous iliac crest bone grafting results in successful salvage of humeral shaft nonunion after prior failed surgical interventions.
