Outcomes following adolescent athlete proximal hamstring apophyseal avulsion bone fragment excision and direct tendon-ischial tuberosity reattachment.

Apophyseal proximal hamstring bone avulsion is uncommon, occurring in adolescents following sudden forceful contraction of the musculotendinous unit. It can be severely disabling, preventing return to sport. This study assessed outcome following avulsed bone excision and direct hamstring tendon-ischial tuberosity reattachment using bone anchors.

Osteointegration of hydroxyapatite-coated collars in cemented massive endoprostheses following revision surgery.

Aims: Hydroxyapatite (HA)-coated collars have been shown to reduce aseptic loosening of massive endoprostheses following primary surgery. Limited information exists about their effectiveness in revision surgery. The aim of this study was to radiologically assess osteointegration to HA-coated collars of cemented massive endoprostheses following revision surgery.

Quality of the femoral cement mantle in total hip arthroplasty using the direct anterior hip approach.

Background: Limited literature exists concerning the femoral cement mantle quality that can be achieved through an anterior approach in total hip arthroplasty (THA). We radiologically evaluated the quality and thickness of the femoral cement mantle in patients undergoing THA utilizing the direct anterior approach (DAA).

Methods: Immediate postoperative anteroposterior and lateral radiographs of 116 consecutive patients who underwent hybrid or fully cemented THA using the DAA and cemented Quadra-C stem (Medacta, International, SA, Switzerland) were assessed by 2 arthroplasty surgeons blinded to the study.

The surgical repair of proximal hamstring avulsions.

Aims: Despite the increase in the surgical repair of proximal hamstring tears, there exists a lack of consensus in the optimal timing for surgery. There is also disagreement on how partial tears managed surgically compare with complete tears repaired surgically. This study aims to compare the mid-term functional outcomes in, and operating time required for, complete and partial proximal hamstring avulsions, that are repaired both acutely and chronically.

Lesions of the abductors in the hip.

Abductor tendon lesions and insertional tendinopathy are the most common causes of lateral thigh pain. Gluteal tendon pathology is more prevalent in women and frequency increases with age.Chronic atraumatic tears result in altered lower limb biomechanics.

Validation of the Sydney Hamstring Origin Rupture Evaluation (SHORE).

Aims: To validate the Sydney Hamstring Origin Rupture Evaluation (SHORE), a hamstring-specific clinical assessment tool to evaluate patient outcomes following surgical treatment.

Methods: A prospective study of 70 unilateral hamstring surgical repairs, with a mean age of 47.3 years (15 to 73).

Diagnosis and treatment of anteroinferior capsular redundancy associated with anterior shoulder instability using an open Latarjet procedure and capsulorrhaphy.

Purpose: There is a paucity of data detailing management of anterior capsular redundancy (ACR) when using the Latarjet procedure for unidirectional instability. This study aimed to describe the surgical management and to assess the clinical profile of patients presenting with anterior capsular redundancy [ACR(+)] with anterior shoulder instability.

Methods: Seventy-seven patients who had a Latarjet procedure were followed for a 55-month period.

Volumetric definition of shoulder range of motion and its correlation with clinical signs of shoulder hyperlaxity. A motion capture study.

Background: Shoulder hyperlaxity (SHL) is assessed with clinical signs. Quantification of SHL remains difficult, however, because no quantitative definition has yet been described. With use of a motion capture system (MCS), the aim of this study was to categorize SHL through a volumetric MCS-based definition and to compare this volume with clinical signs used for SHL diagnosis.

How can we optimize anterior iliac crest bone harvesting? An anatomical and radiological study.

Purpose: Anterior iliac crest bone is a widely used donor site for bone harvesting. It provides an autologous bone graft consisting of cancellous bone that can be packed or cortical bone with greater structural support. Uses include spinal fusion and fracture non-union surgery.

Preserving the superficial branch of the radial nerve during carpometacarpal and metacarpophalangeal joint arthroscopy: an anatomical study.

Background: The superficial branch of the radial nerve (SBRN) is potentially at risk during thumb carpometacarpal (TCM) or thumb metacarpophalangeal (TMP) joint arthroscopy. The aim of this anatomical study was to describe the different branching patterns of the SBRN and to optimize positioning of portals during TCM and TMP arthroscopy.

Methods: The SBRN was dissected in 30 forearms.

Cochlear implant infection due to cholesteatoma.

There are an increasing number of young children undergoing cochlear implantation. Cholesteatoma is a serious, although rare, long-term complication. We present the only documented case in which cholesteatoma has presented with late abscess formation in the bed of a cochlear implant package of a child.

Aneurysmal bone cyst of the paediatric shoulder girdle: a case series and literature review.

Limited research has analysed paediatric shoulder girdle aneurysmal bone cyst management and outcomes. This study analysed locations affected, investigations, treatments and recurrence in children treated at the London Bone Tumour Unit between 1998 and 2004 and in English and French literature between 1956 and 2004. The proximal humerus and clavicle are most frequently affected whereas scapula involvement is rare.

Influence of modern studded and bladed soccer boots and sidestep cutting on knee loading during match play conditions.

Background: The influence of modern studded and bladed soccer boots and sidestep cutting on noncontact knee loading during match play conditions is not fully understood.

Hypothesis: Modern soccer boot type and sidestep cutting compared with straight-ahead running do not significantly influence knee internal tibia axial and valgus moments, anterior joint forces, and flexion angles.

Study Design: Controlled laboratory study.

The incidence of multiple level noncontiguous vertebral tuberculosis detected using whole spine MRI.

The commonest site of osseous tuberculosis is the spine. Most vertebral lesions are contiguous. Current research indicates the incidence of multiple level noncontiguous vertebral tuberculosis is 1.

Scoliosis development in identical twins after intercostal thoracotomy for pulmonary artery sling correction.

We present a report on two monozygotic female twins who underwent a left-sided intercostal thoracotomy in the second month of life for pulmonary artery sling correction. Twenty-four years later, in adulthood, the identical twins had both developed right-sided thoracic scoliosis. No previous accounts of scoliosis development after intercostal thoracotomy for pulmonary artery sling correction have been reported.
