Reoperation risk of periprosthetic fracture after primary total hip arthroplasty using a collared cementless or a taper-slip cemented stem.

Aims: The aim of this study was to determine both the incidence of, and the reoperation rate for, postoperative periprosthetic femoral fracture (POPFF) after total hip arthroplasty (THA) with either a collared cementless (CC) femoral component or a cemented polished taper-slip (PTS) femoral component.

Methods: We performed a retrospective review of a consecutive series of 11,018 THAs over a ten-year period. All POPFFs were identified using regional radiograph archiving and electronic care systems.

Outcomes of Selective Arthrodesis Based on Joints Affected in 33 Feet With Müller-Weiss Disease.

No consensus exists regarding operative treatment of Müller-Weiss disease (MWD). Its only classification is based solely on Méary's angle and serves neither as guide to management nor prognosis. We report on 33 feet that underwent surgery following failed conservative management.

Towards understanding Müller-Weiss disease from an analysis of 95 cases.

Background: The single existing classification of Müller-Weiss Disease (MWD), based solely upon Méary's angle, serves neither as guide for prognosis nor treatment. This accounts for lack of gold standard in its management.

Methods: Navicular compression, medial extrusion, metatarsal lengths, Kite's, lateral and dorsoplantar talo-first metatarsal angles were measured in 95 feet with MWD.

Misdiagnosis of Extraskeletal Osteochondroma in the Foot: A Report of 3 Cases.

Cases: Two women presented with newly growing callosities beneath the first and second metatarsal heads, initially believed to reflect gastrocnemius tightness and plantar plate pathology. In another man, swelling at the posterolateral aspect of the heel was mistaken for a Haglund deformity. Subsequent imaging of each patient led to delayed diagnosis of extraskeletal osteochondroma (ESO).

Concomitant Dislocation of the Hallucal Interphalangeal Joint and Extra-Articular Dislocation of Its Sesamoid: A Case Report.

Case: A 22-year-old man sustained closed dislocation of the hallucal interphalangeal joint (HIPJ). Painful limitation of movements persisted 2 months after closed reduction. Magnetic resonance imaging revealed dislocation of the hallucal interphalangeal joint sesamoid (HIPJS) from its intra-articular attachment on the superior surface of the plantar plate to an extra-articular subcutaneous location, plantar and lateral to the flexor hallucis longus tendon.

The lateral malleolar bony fleck classified by size and pathoanatomy: The IOFAS classification.

Background: This study analyzes position of the peroneal tendons and status of the superior peroneal retinaculum (SPR) whenever a lateral malleolar bony flake fracture occurs.

Methods: Twenty-four patients had a lateral malleolar bony fleck on anteroposterior ankle radiographs, either in isolation or associated with other hindfoot injuries. We studied size of the bony flecks, presence or absence of peroneal tendon dislocation and pathoanatomy on CT scans.

Irreducible tongue-type calcaneal fracture due to interposition of flexor hallucis longus.

We present a rare case of interposition of the flexor hallucis longus (FHL) tendon blocking percutaneous closed reduction of a displaced tongue-type calcaneal fracture, and necessitating open repositioning of the tendon and internal fixation through a single extensile lateral approach. Although not recognized until during surgery, with a high index of suspicion, preoperative diagnosis of this injury combination should be possible on high resolution CT, thus enabling better planning of the procedure. The presence of a small sustentacular fragment, especially if markedly displaced or rotated, should further alert the physician as to increased likelihood of such tendon entrapment within the fracture.

Vertical axis dislocation with coronal fracture of the patella: A previously unreported injury pattern.

The patella usually dislocates laterally. Less commonly, intra-articular dislocation occurs about either the vertical or horizontal axis. Patellar fractures are generally transverse with varying degrees of comminution, and less frequently vertical in the sagittal plane.

Reconstruction of healed elongated anterior tibial and extensor hallucis longus tendons in a young active farmer.

A case of open traumatic lacerations of the anterior tibial tendon (ATT) and extensor hallucis longus (EHL) tendon that both healed in continuity but significantly elongated position following primary repair, resulting in foot drop and sagging of the great toe affecting gait and function, is presented. An adequate immobilization and protection in the early post-operative period is very important and a secure technique for reconstructing a healed elongated anterior tibial tendon is described.
