Rest Activity

– See: EMG Menu: – Discussion:     – normally there is no activity at resting muscle;     – denervated muscle fibers become spontaneously active, producing fibrillation potentials & positive sharp waves approx 10-20 days after             nerve injury;     – this test assists in differentiating neuropathic muscle atrophy from myopathic atrophy

Reperfusion Injury / Crush Injury

– See: Compartment Syndrome – Discussion:     – traumatic rhabdomyolysis, or crush syndrome, is consequence of prolonged continuous pressure on the limbs;     – it reflects disintegration of muscle tissue & influx of myoglobin, potassium, and phosphorus into the circulation;     – syndrome is characterized by hypovolemic shock and hyperkalemia;     … Read more

Open Repair of Supraspinatus / Infraspinatus Tear

– Rotator Cuff Tear – Discussion:  – arthroscopic repair techniques – clinical outcomes of repair      – indications for RTC tear: – shoulder pain (especially night pain); – symptoms which cause loss of function or quality of life; – failure of NSAIDS and formal physical therapy; – failure of series of marcaine / steroid injections; – full passive ROM pre-op is necessary … Read more

Repair of the Torn Meniscus

– Meniscal Anatomy and Physiology: – medial meniscus – bucket handle meniscus tear – posterior horn tears of medial meniscus – lateral meniscus – discoid meniscus – indications for repair: – any peripheral nondegenerative longitudinal tears < 3 cm; – if tear is w/in 3 mm of the periphery, it is considered vascular; – area … Read more

Repairs of the Lateral Meniscus

– See: Lateral Meniscus /  General Discussion of Meniscal Repair – Indications: – any peripheral nondegenerative longitudinal tears < 3 cm; – if tear is w/in 3 mm of the periphery, it is considered vascular; – area 3-5 mm from periphery is grey zone, & > 5 mm from periphery is considered avascular; (see vascularity of … Read more

Release of Elbow Flexion Contracture Thru Kocher Approach

– See:       – Kocher Approach:       – Elbow Flexion Contracture: – Discussion:     – goal of procedure is elevation of common extensor tendon and transection of the anterior joint capsule;     – indicated for significant flexion contractures (more than 30 deg) which arise from soft tissue (capsular contracture);   … Read more

Renal Osteodystrophy

– See:          – Calcitriol          – Hyperparathyroidism          – Renal Failure: (Orders for the CRF Patient)          – Renal Spondyloarthropathy          – Vit D – Effects on Adult Bone:     – abnormalities of renal function can produce profound bone disease;     … Read more

Renal Spondyloarthropathy

– See: Renal Osteodystrophy – Discussion:     – seen in hemodialysis patients with chronic renal failure and typically invovles three adjacent vertebrae with intervening discs;     – changes include subluxation, degeneration, and narrowing of disc ht;     – although the process may resemble infection, it probably represents crystal or amyloid deposition;     – … Read more
