Chronic exertional compartment syndrome and medial tibial stress syndrome are uncommon conditions that affect long-distance runners or players involved in team sports that require extensive running. We report 2 cases of bilateral chronic exertional compartment syndrome, with medial tibial stress syndrome in identical twins diagnosed with the use of a Kodiag monitor (B. Braun Medical, Sheffield, United Kingdom) fulfilling the modified diagnostic criteria for chronic exertional compartment syndrome as described by Pedowitz et al, which includes: (1) pre-exercise compartment pressure level >15 mm Hg; (2) 1 minute post-exercise pressure >30 mm Hg; and (3) 5 minutes post-exercise pressure >20 mm Hg in the presence of clinical features. ⋯ However, some authors have found that no significant difference exists in the relative perfusion, in patients, diagnosed with chronic exertional compartment syndrome. Magnetic resonance images of affected compartments have indicated that the pain is not due to ischemia, but rather from a disproportionate oxygen supply versus demand. We believe this is the first report of chronic exertional compartment syndrome with medial tibial stress syndrome in twins, raising the question of whether there is a genetic predisposition to the causation of these conditions.

The purpose of this retrospective study was to investigate the clinical and radiological outcomes following corrective osteotomy for nascent malunion of distal radial fractures with dorsal tilt using palmar-locking plates without using autologous structural bone grafting for dorsal cortex support. The fractures were dorsally angulated distal radial fractures (AO types A2, A3, and C1) with neglected or delayed treatment for 5 to 8 weeks. Fractures were repaired using 2.4-mm palmar locking plates. ⋯ No further changes were apparent between 4.5- and 12-month follow-up. The palmar locking plates provided sufficient stability for corrective osteotomy within 8 weeks of injury without the need for structural bone grafting. Furthermore, casting immobilization was also unnecessary, and a good wrist range of motion was restored early after rehabilitation.

Symptomatic spinal epidural lipomatosis is a rare disorder characterized by overgrowth of fat in the extradural space. Most patients have an underlying endocrine disorder, such as Cushing's syndrome, or have taken exogenous steroids chronically. Although less common, obesity alone is thought to be a cause of spinal epidural lipomatosis, representing <25% of reported cases. ⋯ Based on our review, our 2 patients are considerably younger than those in past reports, especially in the patient group to which the steroid was not administered. In addition, few cases exist of spinal epidural lipomatosis with acute sphincter dysfunction and paraparesis. Our cases suggest that morbid obesity can lead to juvenile spinal epidural lipomatosis with acute neurological changes.

Nonsteroidal anti-inflammatory drugs (NSAIDs) may prevent heterotopic ossification after total hip arthroplasty (THA). Cyclooxygenase 2 (COX-2) inhibitors may minimize side effects. The goal of this review was to compare the effectiveness and side effects of the perioperative use of selective COX-2 inhibitors with those of conventional NSAIDs in patients undergoing THA. ⋯ Prevention of heterotopic ossification and side effects with COX-2 inhibitors were significant in 2 studies. Discontinuation for side effects was not significant. COX-2 inhibitors do not prevent heterotopic ossification after THA significantly better than conventional NSAIDs, while they are advantageous regarding side effects.

Avulsion fractures of the tibial tuberosity are typically sustained by adolescent males during sporting activities. Tibial tuberosity avulsions with simultaneous proximal tibial epiphyseal fractures are rare injuries. We present an unusual case of Ogden type IIIA avulsion fracture of tibial tuberosity with a Salter Harris type IV posterior fracture of proximal tibial epiphysis in a 13-year-old boy. ⋯ Our case highlights the importance of vigilance and a high index of suspicion for coexisting fractures or soft tissue injuries when treating avulsion fractures of tibial tuberosity. A CT scan is justified in such patients to recognize complex fracture configurations, and surgical treatment should be directed appropriately to both the fractures followed by early rehabilitation. Patients with such injuries warrant close monitoring for compartment syndrome during the perioperative period.
