Coccydynia: A REVIEW OF PATHOANATOMY, AETIOLOGY, TREATMENT AND OUTCOME

Coccydynia is a painful disorder characterised by coccygeal pain which is typically exaggerated by pressure. It remains an unsolved mystery because of the perceived unpredictability of the origin of the pain, some psychological traits that may be associated with the disorder, the presence of diverse treatment options, and varied outcomes. A more detailed classification based on the aetiology and pathoanatomy of coccydynia helps to identify patients who may benefit from conservative and surgical management. This review focuses on the pathoanatomy, aetiology, clinical features, radiology, treatment and outcome of coccydynia.

Update on rehabilitation following ACL reconstruction

As anterior cruciate ligament (ACL) reconstruction has evolved to less invasive, more anatomical approaches, rehabilitation of the injured athlete has likewise become more progressive and innovative, with a sound understanding of graft and fixation strength and biologic healing-remodeling constraints. This review discusses these innovations including specific considerations before surgery, when planning rehabilitation timetables, and the importance of reestablishing nonimpaired active and passive knee range of motion and biarticular musculotendinous extensibility in positions of function. Concepts of self-efficacy or confidence and reestablishing the “athlete role” are also addressed. Since ACL injury and reinjury are largely related to the influence of structure-form-function on dynamic knee joint stability, the interrelationships between sensorimotor, neuromuscular, and conventional resistance training are also discussed. Although pivot shift “giving way” relates to function loss following ACL injury, anterior translational laxity often does not. Although there is growing evidence that progressive eccentric training may benefit the patient following ACL reconstruction, there is less evidence supporting the use of functional ACL knee braces. Of considerable importance is selecting and achieving a criteria-based progression to sports-specific training, reestablishing osseous homeostasis and improved bone density, blending open and closed kinetic chain exercises at the appropriate time period, and appreciating the influence of the trunk, upper extremities, and sports equipment use on knee loads. We believe that knee dysfunction and functional recovery should be considered from a local, regional, and global perspective. These concepts are consolidated into our approach to prepare patients for return to play including field testing and maintenance training.

TOURNIQUET USE AND SICKLE CELL HEMOGLOBINOPATHY: HOW SHOULD WE PROCEED?

The use of tourniquets for upper and lower extremity operative procedures is controversial in patients with sickle cell hemoglobinopathies. The authors used Ovid and MEDLINE®, PubMed, and CINAHL® to detect English-language reports of any surgical procedure where a tourniquet was used on a patient with sickle cell disease or trait. Four papers met the search criteria and were reviewed. These studies included 96 patients with hemoglobin SS, SC, and sickle cell trait (AS). The investigations differed in tourniquet type, perioperative care, operative procedure, and patient genotype distribution. Twelve of 96 sickle cell patients (12.5%) experienced postoperative complications (8 SS/SC and 4 AS) detailed in two of the four studies. Nonetheless, the available limited evidence suggests that with proper perioperative management and necessary precautions, tourniquets can be used with relative safety in most patients with sickle cell disease.

The management of nonunion and delayed union of patella fractures: a systematic review of the literature.

Nonunion and delayed union of patella fractures are rare conditions that are fraught with challenges. There exists limited evidence in the literature to guide the clinician in the management of these complications. Therefore, the purpose of this study was to perform a systematic review of the available evidence on the management of nonunion and delayed union of patella fractures. A total of five publications which met our criteria were identified and formed the basis of this study. The decision making in the treatment of this condition is based on the functional demands of the patient, the factors that led to the development of the nonunion, the potential impact of the biomechanical effects of a total patellectomy, and the presence of an intact extensor mechanism of the knee for a later reconstructive procedure. Patients with low functional demands may be managed with nonoperative methods; however, those who perform heavy physical work or participate in sports usually require open reduction and internal fixation. Tension band wiring is the treatment of choice for patients suitable for a reconstructive procedure. Partial or total patellectomy is also an option for small distal fragments or an inability to satisfactorily perform internal fixation.

Conservative Treatment of Patellofemoral Joint Instability

Conservative and postsurgical rehabilitation following medial patellofemoral ligament injury is poorly described in the literature, with most interventions focusing exclusively on the knee joint. During single lower extremity jump landings, the three-dimensional lower extremity loading response at impact often includes a contralateral pelvic drop and associated trunk movements, femoral and tibial internal rotation, knee valgus, and foot pronation. Therefore, local (knee), regional (entire lower extremity), and more global (entire lower extremity in addition to core, upper body) factors need to be considered when attempting to treat or to prevent patellofemoral joint instability. The rehabilitation clinician must carefully blend local treatments with regional, and global therapeutic exercise interventions to develop coordinated lower extremity neuromuscular movement synergies that integrate the core and upper extremities in a functionally relevant manner. The ultimate goal is pain-free, three-dimensional dynamic knee stability. Paramount to attaining effective dynamic knee stability is having sufficient eccentric muscle function to withstand activity-specific loads. Criterion based return to sport specific training guidelines, and self-reported surveys including items and item scoring weights that are more specific to athletic performance requirements are needed.
