PURPOSE: In this article, we summarize our work on understanding the influence of cervical sagittal malalignment on the mechanics of the cervical spine. METHODS: Biomechanical studies were performed using an ex vivo laboratory model to study the kinematic and kinetic response of human cervical spine specimens in the setting of cervical sagittal imbalance. The model allowed controlled variations of C2-C7 Sagittal Vertical Alignment (C2-C7 SVA) and T1-Slope so that clinically relevant sagittally malaligned profiles could be prescribed, while maintaining horizontal gaze, and their biomechanical consequences studied...

We present seven cases of a relatively rare swan neck deformity resulting from chronic radial collateral ligament (RCL) injury of the proximal interphalangeal (PIP) joint in the little finger. All patients were middle-aged women (mean 51 years old, range 42-55), and the duration between the initial injury and surgery was 20 years (range 5-40). The chief complaint was painful snapping of the PIP joint. All patients had hyperextension and ulnar deviation of the PIP joint with mobile swan neck deformities that had not improved with conservative treatment...

BACKGROUND: A certain percentage of patients undergoing anterior cruciate ligament (ACL) reconstruction will experience graft failure, and there is mounting evidence that an increased posterior tibial slope (PTS) may be a predisposing factor. Theoretically, under tibiofemoral compression force (TFC), a reduced PTS would induce less anterior tibial translation (ATT) and lower ACL force. HYPOTHESIS: Ten-degree anterior closing wedge osteotomy of the proximal tibia will significantly reduce ACL force and alter knee kinematics during robotic testing...

Solitary ankle fracture or Achilles Tendon (AT) rupture might not be an uncommon injury. However, concomitant ipsilateral ankle fracture with AT rupture is rare. The present report discusses this rare combination. A 30-year-old female had fallen while rock climbing and sustained a closed fracture of the medial malleolus with an ipsilateral complete AT rupture. Most of the reported cases had similar patterns, not only in terms of history, but also in terms of a similar fracture pattern. This rare combination of orthopedic injuries tends to occur when an abrupt excessive force is applied to the forefoot, with subsequent ankle hyperextension or hindfoot inversion...

The skydiving/parachuting sport which has recently gained popularity is also known for its accidents and injuries. However, there are a few studies related to its occupational ergonomic risks and occupational musculoskeletal diseases. It has been reported that the sudden hyperextension of the neck during the parachute opening, so called opening shock results in neck pain. It has been found that the jumpers are subjected to an average deceleration of 3-5 times the earth's gravitational acceleration (3-5 G) during parachute opening shock...

Ehlers-Danlos syndromes (EDS) are a heterogeneous group of inheritable connective tissue disorders characterized by skin hyperextensibility, joint hypermobility and cutaneous fragility with delayed wound healing. Over and above these common features, they differ in the presence or absence of various organ and tissue abnormalities, and differences in genetic causal mechanisms and degree of severity. They are complex and multisystem diseases, with the majority being highly disabling because of major joint problems and neurosensory deficiencies, and in some cases, they may be life-threatening due to associated complications, especially vascular disorders...

INTRODUCTION: The management of volar plate avulsion fractures in the context of a stable joint and a bony fragment of less than 30% has traditionally been conservative. This study was performed to assess volar plate healing with high-resolution ultrasound in order to provide early full mobilization. MATERIAL AND METHODS: Between January 2012 and December 2013, 78 patients with volar plate injuries of the proximal interphalangeal (PIP) joints (42 distortions and 36 dislocations) were treated conservatively in our department for volar plate avulsion fracture associated with stable joint and bony fragment inferior to 30% of the intra-articular surface assessed both by radiography and ultrasound...

The 2017 EDS revised nosology indicates that minimal criteria suggestive for classical Ehlers-Danlos syndrome (cEDS) are skin hyperextensibility plus atrophic scarring together with either generalized joint hypermobility (gJHM) and/or at least three minor criteria that include cutaneous features and gJHM complications. Confirmatory molecular testing is obligatory to reach a final diagnosis. Although the large majority of the patients presents with these clinical features, some do not and might remain undiagnosed or misdiagnosed...

STUDY DESIGN: Spondylolysis is a defect in the portion of pars interarticularis. The latter affects approximately 6% of the population. It is caused by repetitive trauma in hyperextension. Low back pain is the most common symptom. METHODS: We implanted interspinous process devices in 12 patients with isthmic lysis without spondylolisthesis for low back pain. The purpose of the surgery was to conduct a minimally invasive procedure. RESULTS: In eight cases, patients became asymptomatic...

We present a case of a 19-year-old woman with a forced hyperextension trauma of the knee causing a posteromedial fracture, a medial meniscus root tear and rupture of the posterior cruciate ligament. The posteromedial fracture of the tibial plateau was treated operatively with open reduction and internal fixation. Anatomical reconstruction was achieved. Postoperative treatment included unlimited flexion and minimal weight bearing. After 3 months, the patient had minimal pain after weight bearing and returned to preoperative range of motion...

Locking of the metacarpophalangeal (MCP) joint is commonly caused by hyperextension of the thumb or moderate flexion of the index or middle finger. We report a rare case of vertical locking of the MCP joint of the little finger in a 16-year old female after blunt trauma to the little finger. The MCP joint was locked when positioned at approximately 90-degree-flexion and could not extend actively or passively. A manual reduction was easily achieved and no immobilization was applied. Vertical locking of the MCP joint can be easily reduced, and immobilization is unnecessary after reduction...

STUDY DESIGN: Descriptive Epidemiological Study. INTRODUCTION: Ligament tears between carpal bones are easily missed on initial presentation, but can have potentially debilitating effects on the patient if they progress to an instability. They are usually the result of a fall onto an outstretched hand with the wrist in hyperextension. Current incidence of carpal instability after these falls is unknown. PURPOSE OF THE STUDY: Using established clinical and radiological measures, we sought to establish the cumulative incidence of carpal instability in people who have fallen onto an outstretched hand in the second year after injury...

INTRODUCTION: Previous studies have shown that hyperlordotic C1-C2 fusion was related to postoperative subaxial kyphosis. However, most of the patients in these studies were complicated with rheumatoid arthritis (RA). Moreover, no studies have specifically evaluated the relationship between C1-C2 fusion angle and cervical sagittal vertical axis (cSVA), T1 slope or cranial tilt (CRT) after posterior C1-C2 fusion. This study aimed to investigate the cervical sagittal alignment in non-RA patients following posterior C1-C2 fusion and the correlation between C1-C2 fusion angle and postoperative cervical sagittal alignment...

BACKGROUND: A common adage among hand surgeons is that the symptoms of trapeziometacarpal (TMC) arthrosis vary among patients independent of the radiographic severity. We studied factors associated with radiographic severity of TMC arthrosis, thumb pain, thumb-specific disability, pinch strength, and grip strength in patients not seeking care for TMC arthrosis. Our primary null hypothesis was that there are no factors independently associated with radiographic severity of TMC arthrosis according to the Eaton classification among patients not seeking care for TMC arthrosis...

PURPOSE OF REVIEW: Joint hypermobility is a common, although largely ignored physical sign. Joint hypermobility is often asymptomatic but may be a feature of an underlying genetic disorder with systemic manifestations. The present article presents a comprehensive approach to considering joint hypermobility and clinically related issues in children and adults. RECENT FINDINGS: Ehlers-Danlos syndrome (EDS) is an umbrella term for various Mendelian connective tissue disorders sharing joint hypermobility, skin hyperextensibility, and tissue fragility...

PURPOSE: To evaluate the outcome of revision surgery for failed thumb carpometacarpal (CMC) arthroplasty. METHODS: We retrospectively analyzed 32 patients with failed thumb CMC arthroplasty. The primary reason for revision was pain caused by metacarpal subsidence. Revision surgery included soft tissue interposition and distraction pinning to address the metacarpal subsidence. Additional ligament reconstruction was performed in patients with thumb instability. Eight patients required additional metacarpophalangeal joint fusion for concomitant joint hyperextension...
