Lesions of heterotopic ossification were excised from thirty-seven joints in twenty-three adults who had injuries to the brain. The lesions elbows, twelve hips, and two shoulders. Patients retrospectively divided into five categories according neural residua (cognitive physical deficits). patients Class I (minimum cognitive disability) II disability moderate fair or good selective control affected extremity best prognosis for maintaining range motion resulting resecting lesion improving...

This is a retrospective study of retrograde intramedullary rodding for ankle arthrodesis in 19 ankles 16 patients. The preoperative diagnosis patients was diabetic neuropathic arthropathy seven patients, rheumatoid arthritis three post traumatic arthrosis paraplegia with fixed equinovarus the foot two and avascular necrosis talus one patient. Retrograde done as salvage procedure each Fourteen had radiographic evidence solid arthrodesis. In four five pseudarthrosis, no case clinically...

To promote early full weight-bearing and rapid rehabilitation, 20 elderly patients (average age, 82.2 years) with unstable intertrochanteric hip fractures were treated a bipolar head-neck replacement. Seventeen had the prosthesis inserted as primary fracture management, three, for salvage of failed internal fixation. The ambulating unrestricted at an average 5.5 days after operation. design may permit conversion to total arthroplasty without removal femoral component, reduce risk acetabular...

There were 157 patients following major lower extremity amputation who evaluated to determine functional prosthetic ambulation. Twenty-eight in the amputee clinic and found not be candidates for fitting. Forty-one fit with a prosthesis but did become ambulators. Eighty-eight became Of all above-the-knee amputees, 46% Only 19% of bilateral amputees below-the-knee 66% The presence coronary artery disease decreased ambulatory potential or amputees. A screening method elderly, dysvascular should...

Surgical treatment of supracondylar fractures the femur has become commonplace. A variety surgical implants are available. In carefully chosen patients treated with appropriate technique, early motion and good knee function can be obtained open reduction internal fixation. However, morbidity (and mortality) substantial following complications fixation femur. We present a series 30 consecutive referred to Rancho Los Amigos Medical Center for fractures. Three septic pseudarthrosis underwent...

Background: Near-infrared spectroscopy measures the percentage of hemoglobin oxygen saturation in microcirculation tissue up to 3 cm below skin. The purpose this study was describe measurable response normal oxygenation leg after acute trauma with use technique. Methods: Twenty-six patients unilateral tibial fractures and twenty-five uninjured volunteer control subjects were enrolled. measurements obtained for both legs all four compartments: anterior, lateral, deep posterior, superficial...

Summary Increased osteogenesis, both in fracture healing and heterotopically, occurs a significant percentage of patients with traumatic brain injury. Periarticular heterotopic ossification, especially the hip elbow joint, can cause functional loss motion injury interfere activities daily living. Seventeen had periarticular ossification resected 20 joints (13 hips seven elbows). Each joint was ankylosed prior to surgical resection (Brooker IV). In immediate postoperative period, average arc...

Since the advent of effective antiretroviral therapy, number people with AIDS has increased and a certain percentage these patients will require emergent orthopaedic surgery. Little is known regarding infections association CD4 counts postoperative infection in HIV who experience trauma.

The results of 59 surgical procedures for correction spastic equinovarus deformity the foot using split anterior tibial tendon (SPLATT) were reviewed in 54 adults with traumatic head injury. mean time follow-up was 49.7 months. Thirty-nine individuals had hemiplegic involvement, three triplegic and 12 quadriplegic. Evaluation patterns lower extremity muscle activity preoperatively by dynamic electromyography 33 patients showed no significant difference from that seen stroke population,...

Late infections remain a significant complication in the treatment of open fractures, occurring 2% to 25% all fractures. Recently there has been trend toward early soft-tissue coverage fracture wounds. Quantitative bacterial counts have used primarily by plastic surgeons assess viability primary versus delayed wound closures. were obtained 52 consecutive fractures 50 patients correlation between quantitative and subsequent sepsis, determine effect time debridement on count, finally review...

In a brief study of the feasibility welding sintered a‐Sic, solid‐state and brazing were investigated. Joint quality was determined solely by microstructural examination. Hot‐pressure shown to be feasible at 1950°C. Diffusion also successful under hot isostatic pressure 1950°C when boride, carbide, silicide interlayers used. Furnace accomplished 1750°C TiSia interlayer introduced.

Knee motion following femoral fractures is often less than satisfactory. Surgical procedures to increase knee are rarely done. This paper presents a series of nine patients who had severe fractures, primarily in the distal third. Once union was obtained, all flexion incompatible with normal gait (average 30.2 degrees). All underwent quadricepsplasty at Rancho Los Amigos Medical Center. Eight achieved allowing 78 our indications, methods, results, and complications performing achieve fractures.

Abstract Corrosion of steel specimens was monitored in 15 Texas soils order to test the current system for assessing soil corrosivity. Corrosion, measured situ at two depths using electrical resistance probes, a function many properties and could not be adequately described any single property. The system, developed by USDA‐SCS, which places into corrosion potential classes based on characterization data descriptions, found overestimate corrosivity soils. A revised that more accurately...

Metallic reconstruction plates used for fracture stabilization typically require intraoperative contouring patient-specific anatomical fit. Despite this, characterization of plate mechanical properties after has previously been limited. The objective this study was to assess whether affects fatigue resistance three types Stryker seven-hole stainless steel (SS) 316LVM fixation plates. hypothesis that each type, more repetitions would result in lower resistance.Plates were contoured using a...

Railroad-related trauma has been associated with injuries causing considerable morbidity. This is a retrospective study of 15 consecutive patients who were run over by trains. The initial injury produced traumatic amputation 10 extremities in eight patients. Limb salvage two other severe fractures failed, and subsequent lower extremity was required. Despite efforts to the most distal tissue possible, 8 12 amputated acute period required revision more proximal level. Alcohol ingestion...

Spasticity of the posterior calf muscles often occurs following head injury or spinal cord injury. If left untreated, equinovarus contractures foot and ankle may occur in a relatively short time period. This paper retrospectively reviews nine patients with either closed (six patients) (three who underwent open phenol injections into motor branches tibial nerve 16 limbs. was decreased all patients. No significant equinus had occurred at final follow-up. Five were subsequently able to...

Heterotopic ossification (HO) in the knee after tibial intramedullary nailing (IMN) has yet to be thoroughly investigated. Our aim was assess frequency and associated factors for HO IMN.

Proximal femoral resection (i.e., modified Girdlestone procedure) is often required in the paraplegic with an infection or dislocation of hip joint. A philosophy and technique for dealing this difficult problem are presented. The involves using external osseous fixator to stabilize femur allow healing flap used fill defect.
