Total Hip Arthroplasty by the Direct Anterior Approach Using a Neck-preserving Stem: Safety, efficacy and learning curve.

Background: The concept of femoral neck preservation in total hip replacement (THR) was introduced in 1993. It is postulated that retaining cortical bone of the femoral neck offers triplanar stability, uniform stress distribution, and accommodates physiological anteversion. However, data on safety, efficacy and learning curve are lacking.

Safety of Osseointegrated Implants for Transfemoral Amputees: A Two-Center Prospective Cohort Study.

Background: Osseointegrated implants are an alternative for prosthetic attachment for individuals unable to wear a socket following an amputation. The concept of an integrated metal implant communicating with the external environment raises substantial concern about the risk of ascending infection. We report on the safety of press-fit osseointegrated implants currently used in Australia and the Netherlands.

Osseointegrated total hip replacement connected to a lower limb prosthesis: a proof-of-concept study with three cases.

Background: Osseointegrated implants are a suitable alternative for prosthetic attachment in individuals with a transfemoral amputation, who are unable to wear a socket. However, the small bone-implant contact area, reduced muscular leverage, and osteoporosis contraindicate osseointegrated implant use in transfemoral amputees with osteoporosis and a short residuum. We report on the feasibility of combining total hip replacement (THR) with an osseointegrated implant for prosthetic attachment.

Minimally invasive medial patellofemoral ligament reconstruction for patellar instability using an artificial ligament: A two year follow-up.

Background: Recurrence of acute patellar dislocation affects approximately 30% of individuals, and up to 75% of those with grade IV instability. The medial patellofemoral ligament (MPFL) is considered to be critical for patellar stabilization. MPFL reconstruction with allografts has been proposed to reduce risk of recurrence, but there is limited evidence about the safety and effectiveness of techniques using synthetic allografts.

Osseointegrated total knee replacement connected to a lower limb prosthesis: 4 cases.

Background And Purpose: Osseointegrated implants are an alternative for prosthetic attachment in individuals with amputation who are unable to wear a socket. However, the load transmitted through the osseointegrated fixation to the residual tibia and knee joint can be unbearable for those with transtibial amputation and knee arthritis. We report on the feasibility of combining total knee replacement (TKR) with an osseointegrated implant for prosthetic attachment.

Arthroscopically assisted fixation of the lesser trochanter fracture: a case series.

Avulsion fractures of the lesser trochanter in adolescents are uncommon. This injury is a result of a sudden forceful contraction of the iliopsoas tendon. It usually occurs during vigorous sport activity.

Caudal epidural steroid injection: a randomized controlled trial.

Study Design:  Prospective study.

Study Rationale:  A recurrent phenomenon, the lifetime prevalence of low back pain has been reported as 54%-80%, while annual prevalence ranges from 15%-45%.1 It is also associated with enormous economic, societal, and health impact.
