INTRODUCTION: Bone regeneration following injury depends on osteoprogenitor cells derived predominantly from the periosteum. Incomplete regeneration has been attributed to both cell-extrinsic factors (e.g., environment, inflammation, mechanical instability) and cell-intrinsic factors (e.g., impaired proliferation or differentiation of stem cells). In the digit amputation mouse model, amputation through the third phalanx (P3) supports complete regeneration, while amputation through the second phalanx (P2) results in callus formation and scarring. Periosteal cells are known to be the major contributing cell source for repair and regeneration. Yet the healing outcomes of P2 and P3 amputations are significantly different. This study tests whether P2 and …

School of Medicine Faculty Publications
BACKGROUND: Anterior cervical discectomy and fusion (ACDF) is a common spinal procedure with a well-established safety profile. While direct vertebral artery injury is rare and typically recognized intraoperatively, delayed posterior circulation stroke is an even less common but major complication. In patients with risk factors for vascular disease, vascular stress from surgical manipulation may predispose them to thromboembolic events that are not immediately apparent. Transient intraoperative neuromonitoring (IONM) changes may represent early, underrecognized indicators of such vascular compromise. OBSERVATIONS: The authors present the case of a 61-year-old male who underwent elective three-level ACDF for degenerative cervical myelopathy. During cage placement, …

The functional limitations associated with the painful stiffness of knee osteoarthritis (kOA) can affect the muscles of the knee, such as the quadriceps femoris (QF) and articularis genu (AG). The vastus medialis oblique (VMO) of the QF complex is particularly sensitive to kOA. The AG, which can be sampled during total knee arthroplasty (TKA) for kOA, can provide information about the condition of the QF when affected by patient-reported disuse, helping to identify indicators of muscle weakness in the synovial fluid. This study compares the structural and gene expression changes between the VMO and the AG collected from patients with …

Adolescent Scoliosis In Autism Spectrum Disorder: Is It Idiopathic Or Syndromic??, Ravi Rajendra, Matthew B. Bratton, Claudia Leonardi, R. Carter Clement
School of Medicine Faculty Publications
Purpose: Minimal data exists on whether adolescents with both autism spectrum disorder (ASD) and scoliosis exhibit distinct curve types or require varying surgical management compared to neurotypical adolescents. Our study at a high-volume scoliosis center compares patterns of scoliosis in ASD patients with those of neurotypical patients. We hypothesized adolescents with ASD would present with atypical scoliosis curve characteristics compared to neurotypical adolescents. Methods: Using ICD-10 codes, we constructed an electronic database of adolescents aged 10 to 18 with diagnoses of both scoliosis and ASD. To avoid confounding with syndromic conditions, adolescents with a syndrome independently associated with scoliosis were …

School of Medicine Faculty Publications
Posterior interosseous nerve (PIN) syndrome refers to a rare compressive neuropathy of the PIN resulting in motor dysfunction of the forearm extensor compartment. Often, surgical exploration will reveal extrinsic structures that mechanically compress the nerve. Less frequently, PIN syndrome has been reported with a visible hourglass-like constriction and no identifiable causative adjacent structures. In our report, we describe an adolescent patient with PIN syndrome and associated hourglass-like constriction of the PIN. For diagnosis, we used physical examination, preoperative imaging, nerve studies, and intraoperative findings. To monitor recovery, we performed serial neurological examinations and documented patient-reported functional outcomes. The patient underwent …

Standard posterior cervical fusion is a common surgical technique that utilizes lateral mass screws and rods for fixation. A relatively new, minimally invasive technique involving interfacet decortication and placement of spacers has shown promise in terms of outcomes. We sought to determine fusion rates and complications of this new technique at our institution to bolster current literature. We retrospectively reviewed all patients that underwent a 3-level or less minimally invasive posterior cervical fusions by a single surgeon. Patients were evaluated to determine fusion rates and postoperative complications. Twenty-eight patients underwent minimally invasive posterior cervical fusion. Twenty-seven demonstrated fusion (96%). One …

Scapulalgia or shoulder pain accounts for 16% of all musculoskeletal complaints in the healthy adult population and becomes more common as we age. When this pain exceeds 3 months in duration, it is deemed to be chronic, and typically treated in an escalating manner. Spanning a continuum of conservative and non-conservative measures, chronic shoulder pain treatments range from rest and physical therapy to surgery. Since each patient presents with a unique spectrum of symptoms a customized treatment plan is often required. Over the lifetime of many of these patients, a variety of treatment options are required. One of these treatment …
