Use of cannulated bone screws, as compared with use of traditional bone screws, has been reported to decrease surgical time, allow for more precise screw placement, and reduce sources of error. Cannulation of the smaller-size screws that are routinely used in foot surgery has not been available until the last few years. This article reports on the use of the small cannulated screws manufactured by Alphatec Manufacturing, Inc (Palm Desert, California). The screw sizes available in the Mini Lag Screw System are 2.7, 3.5, and 4.0 mm. A long-term clinical and radiographic prospective evaluation of 70 procedures performed on 49 patients was conducted. The follow-up time for all patients was 2 years. None of the 70 implants fractured, and seven procedures (in seven patients) resulted in some type of implant-fixation failure. All of the fixation failures, however, appeared to be related to an untoward event or patient noncompliance. These smaller cannulated screws proved to be a reliable and effective means of fixation in foot surgery.

Double Osteotomy

In 92 patients with static foot deformities of II-IV degrees 159 operations were performed. Surgical treatment had for an object to eliminate first ray adduction and stabilize of forefoot. Follow-up within 1-5 years after operation showed that in static platypodia of II degree the resection of exostosis in combination with subcapital wedge-shaped resection of first metatarsal did not prevent the recurrence of great toe valgus deviation. The more effective method was operation by Shede-Brandes and corrective osteotomies of first metatarsal methaphysis using bone graft or porous implant. Fixation of fragments was performed by S-shaped bow with shape memory. In static platypodia of III degree good long-term functional result was achieved after double osteotomy by Logroscino. In patients with static platypodia of IV degree good results were achieved in combination of Logroscino operation with synostosis of first-second or first-third metatarsals by tightening bow with shape memory foot.

Clinical Problems

This retrospective study was undertaken to determine the long-term clinical problems, residual disability, and need for further surgery in patients with iatrogenic hallux varus. Between 1975 and 1985, in 16 (19 feet) of 83 patients who underwent foot surgery for hallux valgus or metatarsus primus varus, hallux varus deformity was noted at 1-year follow-up on dorsoplantar roentgenograms obtained with the patients bearing weight. Thirteen of those patients (16 feet) were reexamined at an average of 18.3 years (220 months) after surgery. The average hallux varus deformity in this group was 10.1°. Eleven patients (12 feet) rated their results as excellent. The average hallux metatarsophalangeal interphalangeal score for all patients was 91.5 points. Only those with extreme hallux varus deformity were dissatisfied or required further surgery.

Object Spinal cord hemangioblastomas are a common protean manifestation of von Hippel-Lindau (VHL) disease and can be associated with significant morbidity. To better define expected outcome and optimal management of these tumors in the context of this neoplasia syndrome, the authors analyzed the findings from patients with VHL disease who underwent resection of spinal cord hemangioblastomas. Methods Consecutive patients with VHL disease who underwent surgery for spinal cord hemangioblastomas with > 6 months follow-up were included in the study. Serial clinical examinations, functional scores, imaging findings, and operative records were analyzed. Results One hundred eight patients (57 male, 51 female) underwent 156 operations for resection of 218 spinal cord hemangioblastomas. One hundred forty-six operations (94%) were performed for symptom-producing tumors. The most common presenting symptoms included hypesthesia (64% of resections), hyperreflexia (57%), dysesthesia (43%), and weakness (36%). Mean follow-up was 7.0 ± 5.0 years (range 0.5–20.9 years). Complete resection was achieved for 217 tumors (99.5%). At 6-months follow-up, patients were stable or improved after 149 operations (96%) and worse after 7 operations (4%). Ventral tumors (OR 15.66, 95% CI 2.54–96.45; p = 0.003) or completely intramedullary tumors (OR 10.74, 95% CI 2.07–55.66; p = 0.005) were associated with an increased risk of postoperative worsening. The proportion of patients remaining functionally stable at 2, 5, 10, and 15 years' follow-up was 93, 86, 78, and 78%. Long-term functional decline was caused by extensive VHL-associated CNS disease (6 patients), VHL-associated visceral disease (1 patient), or non-VHL disease (2 patients). Conclusions Resection of symptomatic spinal cord hemangioblastomas is a safe and effective means of preserving neurological function in patients with VHL disease. Tumor location (ventral or completely intramedullary) can be used to assess functional risk associated with surgery. Long-term decline in neurological function is usually caused by VHL-associated disease progression.

Abstract The posterior maxillary segment frequently suffers from insufficient bone mass to support dental implants. Current bone augmentation methods, including the lateral maxillary approach (ie, hinge osteotomy) and sinus elevation by osteotome, have many shortcomings. The objective of our study was to assess the safety and efficacy of minimally invasive antral membrane balloon elevation (MIAMBE) followed by bone augmentation and implant fixation (executed during the same procedure). Alveolar crest exposure and implant osteotomy were followed by sequential balloon inflations yielding >10 mm MIAMBE. A mix of autologous fibrin and bone particles with bone speckles was injected beneath the antral membrane. Implants were fixated into the osteotomies, and primary closure was performed during the same sitting. A total of 24 patients were enrolled. Successful conclusion of this procedure was accomplished in 91.6% of the initial 12 patients and 100% in the second dozen cases without significant complications. Patient discomfort was minimal. Long-term follow up revealed satisfactory bone formation, resulting in adequate implant stability. We conclude that the protocol of MIAMBE results in an excellent success rate, low complication rate, minimal discomfort, and long-term safety and durability. Because it requires only basic equipment and a short learning curve, this clinical approach should be widely employed.

Abstract Background Despite being a commonly encountered injury in orthopedic practice, controversy surrounds the methods of optimal internal fixation for femoral neck fractures (FNF) in young patients. The objective of the present study is to compare complication rates and failure mechanisms for surgical fixation of FNF using fully threaded headless cannulated screws (FTHCS) versus partial threaded cannulated screws (PTS) in young adults. Methods A total of 75 patients (18–65 years old) with FNF were prospectively treated with close reduction and internal fixation using three parallel FTHCS and compared to a historical control case-matched group (75 patients) with FNF treated by PTS fixation. After 2 years follow-up, rates of fixation failure (including varus collapse, fracture displacement, and femoral neck shortening), nonunion, and avascular necrosis of the femoral head (ANFH) were compared between the two cohorts. The demographic, follow-up information, and radiological images were assessed by independent blinded investigators. Results Patient demographics and fracture patterns were similar in the two patient groups. The overall fixation failure rates were 8% (6/75) in the FTHCS cohort, which was significantly lower than the 25.3% (19/75) seen in the PTS group. Rates of nonunion and ANFH were significantly lower in the FTHCS group when compared to the PTS control group. When stratified by injury severity (high-energy vs. low-energy fractures), the rate of fixation failure was significant lower with the use of FTHCS when compared with PTS for high-energy fractures while there was no difference in the rates of nonunion or ANFH for high or low-energy fracture patterns. Unique to the FTHCS cohort was an atypical screw migration pattern with varus collapse (6/75, 8%). Conclusions The results show that FTHCS fixation could significantly reduce the complication rate of young patients with FNF, especially in high-energy fracture patterns (Garden III–IV, Pauwels III, or vertical of the neck axis (VN) angle ≥ 15°). There was also confirmation that the modes of fixation loosening in the FTCHS group, including screw “medial migration” and superior cutout, were different from the screw withdrawal pattern seen in the PTS cohort.

SummaryThe objective of this study was to describe the use of a titanium 1.5 mm locking plate in the stabilization of atlantoaxial pathology in three toy breed dogs. Two dogs with atlantoaxial subluxation and another dog with an axial fracture, confirmed by diagnostic imaging, were stabilized via a ventral approach with a 1.5 mm titanium 5-hole locking butterfly-plate. Surgical reduction and stabilization were assessed by computed tomography and radiography after surgery. Follow-up evaluation for resolution of neurological signs and possible complications was performed in all three dogs. For long-term assessment, a telephone follow-up was performed. A considerable improvement of neurological signs occurred within two to four weeks after surgery. An excellent clinical outcome was identified in all three patients. Adequate stabilization and resolution of neurological signs in all three dogs was achieved. The stabilization of atlantoaxial surgical conditions in toy breeds with the 1.5 mm titanium 5-hole butterfly locking plate appears to be an effective means of surgical treatment.

ObjectiveThe purpose of this case series is to describe the application of a vascular closure button (VCB) for the repair of haemodialysis access bleeding. The VCB’s main function is not to assist in bleeding control, but instead to provide easy access for removal of tightly placed sutures in the repair.MethodsA retrospective review of patients undergoing ED repair of persistent bleeding from puncture sites in haemodialysis access conduits (HACs) using a VCB was conducted. Study patients were collected from ED visits to Our Lady of Lourdes Medical Center in Camden, New Jersey, USA, between May 2013 and August 2017. Patients were followed until the time of definitive repair of the underlying pathology or until the end of the study period.ResultsSeventeen VCBs were used to control persistent bleeding from HACs in the ED. Sixteen bleeds were the result of recent haemodialysis punctures, while one was from a bleeding site ulcer. All repairs were successful at controlling the bleeding with preserved HAC function in the ED and no delayed thrombosis. Follow-up time ranged from 1 day to 778 days.ConclusionVascular control buttons provide an effective means to control HAC postdialysis bleeding and allow for ease of suture removal without disruption of a repair with no long-term complications.
