Body Fracture

Traumatic lumbosacral joint dislocation (TLSJD) without L7 vertebral body fracture is a rare injury in dogs. This report describes clinical presentation, therapy and outcome in 3 dogs. Three crossbreed dogs with non-ambulatory paraparesis and lumbar pain were referred. Radiographs confirmed TLSJD and dorso-ventral displacement (DVD) was measured pre and postoperatively. Case 1 was treated by percutaneous transilial pinning. Cases 2 and 3 were treated by internal fixation with pins and PMMA. Within 72h after surgery all dogs were able to stand and walk, and faecal incontinence resolved. To the author’s knowledge this is the first description of a case series of TLSJD in the dog. The biomechanics of TLSJD in animals have not been investigated. It is likely that a single trauma severely hyper-extends L7-S1 causing disruption of the supra and inter-spinous ligaments with simultaneous shear and compression forces that cause ventral slipping of the sacrum. Pins and PMMA compared to percutaneous transilial pinning, provided more strength and stability. In conclusion, TLSJD requires appropriate surgical reduction and stabilization to allow fibrous healing of the L7-S1 junction, resulting in satisfactory neurological recovery

OBJECTIVEFew studies describe long-term functional outcomes of pediatric patients who have undergone lumbar microdiscectomy (LMD) because of the rarity of pediatric disc herniation and the short follow-up periods. The authors analyzed risk factors, clinical presentation, complications, and functional outcomes of a single-institution series of LMD patients over a 19-year period.METHODSA retrospective case series was conducted of pediatric LMD patients at a large pediatric academic hospital from 1998 to 2017. The authors examined premorbid risk factors, clinical presentation, physical examination findings, type and duration of conservative management, indications for surgical intervention, complications, and postoperative outcomes.RESULTSOver the 19-year study period, 199 patients underwent LMD at the authors’ institution. The mean age at presentation was 16.0 years (range 12–18 years), and 55.8% were female. Of these patients, 70.9% participated in competitive sports, and among those who did not play sports, 65.0% had a body mass index greater than 25 kg/m2. Prior to surgery, conservative management had failed in 98.0% of the patients. Only 3 patients (1.5%) presented with cauda equina syndrome requiring emergent microdiscectomy. Complications included 4 cases of postoperative CSF leak (2.0%), 1 case of a noted intraoperative CSF leak, and 3 cases of wound infection (1.5%). At the first postoperative follow-up appointment, minimal or no pain was reported by 93.3% of patients. The mean time to return to sports was 9.8 weeks. During a mean follow-up duration of 8.2 years, 72.9% of patients did not present again after routine postoperative appointments. The total risk of reoperation was a rate of 7.5% (3.5% of patients underwent reoperation for the same level; 4.5% underwent adjacent-level decompression, and one patient [0.5%] ultimately underwent a fusion).CONCLUSIONSMicrodiscectomy is a safe and effective treatment for long-term relief of pain and return to daily activities among pediatric patients with symptomatic lumbar disc disease in whom conservative management has failed.

Background Isolated capitate nonunion is rare. No consensus on the appropriate treatment for this condition exists. Case Description We reported two cases of capitate fracture nonunion presenting several months after untreated high-impact wrist trauma. Treatment was delayed as both patients' nonunions were missed on conventional radiographs. Both were ultimately diagnosed with advanced imaging and successfully treated with internal fixation and autogenous bone grafting. The relevant literature pertaining to capitate nonunion was reviewed. Literature Review Immobilization and internal fixation with bone grafting for capitate nonunion have been described in the literature. Loss of vascular supply and progression to avascular necrosis is a concern after capitate nonunion. Clinical Relevance We present two cases and review the literature on the diagnosis and treatment of this rare injury to guide management. Internal fixation with autogenous bone grafting could play a role in management for this rare condition.

Persistent stifle instability is a recognized complication following tibial tuberosity advancement techniques (TTAT). The aim of this study is to report the feasibility and outcome of tibial plateau leveling techniques (TPLT) to treat dogs with persistent lameness, suspected to be secondary to persistent stifle instability, following (TTAT). Medical records of dogs presented for persistent lameness after TTAT were reviewed. Preoperative data included orthopedic examination, lameness score and radiographs. Inclusion criteria included performance of a surgery to address persistent lameness and suspected instability. Short-term follow up data included orthopedic examination and radiographs of the stifle. Long-term follow up was based on postoperative Liverpool Osteoarthritis in Dogs (LOAD) questionnaire. Seven dogs were included in the study. Mean subjective preoperative lameness score was 3 ± 1.53. Mean preoperative patellar ligament angle relative to the tibial plateau (PLATP) was 94° and mean tibial plateau angle (TPA) was 28°. Six dogs had tibial plateau leveling osteotomy and one had modified cranial closing wedge ostectomy. Mean postoperative PLATP was 79° and mean TPA was 5°. Mean subjective lameness score at follow up was 0.57 ± 0.49. Minor complications were present in 2 dogs and major complication in 1 dog. Mean LOAD questionnaire score was 6.6/52. TPLT can be performed after TTAT and may improve clinical function and stability in these cases in which persistent instability is suspected.

Epiphyseal Injury

The Galeazzi-equivalent fracture is a rare injury that occurs in children. The most important issue is the distal ulnar epiphyseal injury. Although there have been some case reports, most of them performed only short term follow-up. This article describes two cases of this fracture with long term follow-up until epiphyseal closure. First case is a 12-year-old girl who sustained a Galeazziequivalent fracture of her right forearm and underwent emergency surgery. At follow-up of 5 years and 10 months postsurgery, radiographs show ulnar growth arrest of one mm and she has mild pain. Second case is a 15-year-old boy who sustained an open Galeazzi-equivalent fracture of his left forearm and underwent emergency surgery. At follow-up of 3 years and 3 months postsurgery, radiographs show no growth arrest of the distal ulna. He has no residual complaint. Long term follow-up is absolutely necessary to monitor ulnar growth.

Abstract Background: Unicameral bone cysts (UBCs) are frequently associated with pathologic fracture due to aggressive osteolysis. Methods/Results: We present a case series (n=5) with complex or refractory bone cysts treated with doxycycline injections that exhibited increased ossification and symptom resolution at short term follow up with minimal side effects. Conclusions: In addition to its antibiotic properties, doxycycline is also known to inhibit matrix metalloproteinases, angiogenesis, and osteoclast activity suggesting that UBCs are dependent on MMP, VEGF or RANKL-mediated osteolysis. Further investigation is warranted regarding the use of doxycycline injections in UBCs.

Level Of Evidence

Background: The treatment of displaced intra-articular calcaneal fractures remains a challenge and the optimal approach is still controversial. The main reason to avoid the extended lateral approach is the high complication rate due to wound healing problems. We report on 16 years of experience with a standardized limited open reduction and internal fixation technique. Methods: Between 2001 and 2017, we prospectively followed 240 consecutive patients operatively treated for a displaced intra-articular calcaneal fracture. Patients with open, multiple, bilateral, extra-articular, and Sanders IV fractures and those lost to follow-up were excluded. A lateral subtalar approach was used, with a cast for 8 weeks and full weightbearing allowed after 12 weeks. Follow-up examinations were scheduled until 24 months. Subjective and clinical assessment included gait abnormality, subtalar and ankle range of motion, and stability and alignment. The American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score was calculated. Alignment was analyzed on standard radiographs. In total, 131 patients were excluded. The remaining 109 patients were followed for a minimum of 24 months (34.4 ± 14.2 [range, 24-102] months). Results: The mean AOFAS score was 87 ± 13 (range, 32-100). “Excellent” and “good” results, as well as hindfoot motion with “normal/mild” and “moderate” restrictions, were seen in 80% of patients. Early reoperations were performed for insufficient reduction (2 patients), delayed wound healing (debridement, 3 patients), and hematoma (1 patient). Late revisions were arthrodesis (3 patients), medializing calcaneal osteotomy (1 patient), and implant removal (53 patients; 49%). Conclusion: The presented approach has remained unmodified for 16 years and resulted in consistently good functional results. The main disadvantage was the high rate of heel screw removal. Level of Evidence: Level IV, retrospective case series.

Background: Percutaneous vertebral augmentation (PVA) under local anesthesia has been widely used to treat osteoporotic vertebral compression fractures and vertebral body tumors. However, the occurrence of spinal cord or nerve root dysfunction may result in poor prognosis for patients. The aim of this study was to analyze the causes of transient paraplegia in 12 patients undergoing PVA. Methods: The medical records of 12 patients with transient paraplegia during PVA in our hospital were analyzed. Data, including operation, vertebral, anesthetic dose, operation time, recovery time, and follow-up, were extracted. Results: Among the 12 patients, ranging in age from 62 years to 83 years, with a mean age of 74 years, 8 were females and 4 were males. The average anesthetic dose injected per vertebral body was 6.38 ml. Patients required an average of 218.75 min to recover sensation and movement completely. However, the amount of anesthetic injected into each vertebral body was not related to the time required for complete recovery. Follow-up showed that all patients had regained normal bilateral sensation and motor function. Postoperative visual analog scale and Oswestry Disability Index values of the 12 patients were significantly improved compared with preoperative values. Conclusion: The complication of transient paraplegia was caused by local anesthetic drugs infiltrating into the spinal canal and inhibiting nerve conduction in the spinal cord.

OBJECTIVE Minimally invasive posterior cervical decompression (miPCD) has been described in several case series with promising preliminary results. The object of the current study was to compare the clinical outcomes between patients undergoing miPCD with anterior cervical discectomy and instrumented fusion (ACDFi). METHODS A retrospective study of 74 patients undergoing surgery (45 using miPCD and 29 using ACDFi) for myelopathy was performed. Outcomes were categorized into short-term, intermediate, and long-term follow-up, corresponding to averages of 1.7, 7.7, and 30.9 months, respectively. Mean scores for the Neck Disability Index (NDI), neck visual analog scale (VAS) score, SF-12 Physical Component Summary (PCS), and SF-12 Mental Component Summary (MCS) were compared for each follow-up period. The percentage of patients meeting substantial clinical benefit (SCB) was also compared for each outcome measure. RESULTS Baseline patient characteristics were well-matched, with the exception that patients undergoing miPCD were older (mean age 57.6 ± 10.0 years [miPCD] vs 51.1 ± 9.2 years [ACDFi]; p = 0.006) and underwent surgery at more levels (mean 2.8 ± 0.9 levels [miPCD] vs 1.5 ± 0.7 levels [ACDFi]; p < 0.0001) while the ACDFi patients reported higher preoperative neck VAS scores (mean 3.8 ± 3.0 [miPCD] vs 5.4 ± 2.6 [ACDFi]; p = 0.047). The mean PCS, NDI, neck VAS, and MCS scores were not significantly different with the exception of the MCS score at the short-term follow-up period (mean 46.8 ± 10.6 [miPCD] vs 41.3 ± 10.7 [ACDFi]; p = 0.033). The percentage of patients reporting SCB based on thresholds derived for PCS, NDI, neck VAS, and MCS scores were not significantly different, with the exception of the PCS score at the intermediate follow-up period (52% [miPCD] vs 80% [ACDFi]; p = 0.011). CONCLUSIONS The current report suggests that the optimal surgical strategy in patients requiring dorsal surgery may be enhanced by the adoption of a minimally invasive surgical approach that appears to result in similar clinical outcomes when compared with a well-accepted strategy of ventral decompression and instrumented fusion. The current results suggest that future comparative effectiveness studies are warranted as the miPCD technique avoids instrumented fusion.

Chondral Fracture

Background: It is unclear whether chondral fragments without bone have the potential to heal after fixation. Controversy exists and opinions differ regarding the optimal treatment of chondral defects after pure chondral fracture. Purpose: To determine clinical and radiographic outcomes after internal fixation of traumatic chondral fragments repaired to bone in the knee. Study Design: Case series; Level of evidence, 4. Methods: A retrospective clinical and radiographic evaluation of 10 male patients with a mean age of 14.6 years (range, 10-25 years) at the time of surgery was performed. Eight of 10 patients were skeletally immature. Patients were selected by operating surgeons per the presence of a large displaced pure chondral fragment on magnetic resonance imaging and confirmed on intraoperative inspection. All patients had a diagnosed traumatic displaced pure chondral fracture of the knee (without bone) and underwent internal fixation with minimum 1-year follow-up. Validated patient-reported and surgeon-measured outcomes were collected pre- and postoperatively. All patients were evaluated at a mean 56 months postoperatively. Results: At surgery, the mean defect size that was primarily repaired with the displaced chondral fragment was 1.9 × 2.0 cm. With minimum 1-year follow-up, there were no clinical failures. All 8 patients who had subsequent magnetic resonance imaging follow-up had radiographic evidence of complete healing of the chondral fragment back to bone. At a mean follow-up of 56 months (range, 13-171 months; median, 36 months), patients had a mean International Knee Documentation Committee score of 94.74 (range, 87.4-100), a mean Marx Activity Scale score of 14.4 (range, 8-16), and a mean Tegner Activity Scale score of 7 (range, 5-9). At final follow-up, all patients except 1 returned to sports. Conclusion: The treatment of large traumatic chondral fragments is controversial. In this select series of 10 young patients who underwent primary repair with internal fixation, there were no failures clinically. Patients demonstrated excellent short-term clinical and radiographic results after fixation of these relatively large chondral fragments in the knee.

Purpose: This study was aimed to review the short-term results of endoscopic percutaneous longitudinal tenotomy for noninsertional Achilles tendinopathy using the Centerline Endoscopic Carpal Tunnel Release instrument (Arthrex). This method simplifies the operation technique, allows a good endoscopic visualisation of the Achilles tendon with very promising results. Methods: We performed multiple percutaneous longitudinal tenotomies under local anesthesia in 24 patients (25 tendons) with Achilles tendinopathy or peritendinitis that had failed conservative treatment between January 2013 and September 2016. All ambulatory procedures consisted of paratenon release and longitudinal tenotomies. The results were reviewed in 22 patients (23 tendons) at an average follow-up period of 22.5 months (range 10-36 months). Patients’ satisfaction and functional outcomes were evaluated using the Victorian Institute of Sports Assessment–Achilles (VISA-A) questionnaire, the pain visual analog scale (VAS), and the functional foot index. Results: Initial results are very promising with excellent results in 12 patients, good results in 9 patients, and fair result in 1 patient. One patient developed a postoperative thrombosis of the operated limb. Another patient developed a hypertrophic painful scar of the incision wound. The VAS for pain decreased drastically after the index procedure and averaged to 0.2 (SD 0.447). The VISA-A questionnaire score had improved from 42 ± 7.2 points preoperatively to 96.8 ± 14.3 points postoperatively (P = .004). The functional foot index decreased from 84 (SD 30.517) to 33.4 (SD 6.452) on the follow-up examination. Conclusions: The endoscopic-assisted longitudinal tenotomies procedure of the Achilles tendon is easily feasible and can be performed on an outpatient basis, produces minimal complications and shows excellent results. The described technique is recommended for all surgeons especially for those familiar with endoscopy of the Achilles tendon. Levels of Evidence: Therapeutic, Level IV: Case Series
