Neurogenic heterotopic ossification in the upper limb.

Neurogenic heterotopic ossifications (NHOs) are periarticular ectopic ossifications that frequently develop after a central nervous system injury, most often a traumatic one. They limit range of motion and cause pain, interfering with limb positioning and function, whether active or passive. Highly described in the lower limbs, NHOs can also develop in the upper limb, with specific characteristics depending on their location. This article provides a summary of the diagnostic and therapeutic management of NHOs in the upper limb, based on the current literature.

Clinical assessment of upper limb hypertonia in central neurological diseases.

The clinical assessment of a hypertonic upper limb in central neurological diseases should be analytical, systematic (shoulder, elbow, extrinsic and intrinsic hand) and focused on the patient or caregiver's wishes and on the expected objectives (esthetic, hygienic, functional). Nerve blocks can help to separate mixed contractures, show the existence of antagonist muscles or find a starter muscle in dystonia patterns. The etiology (especially the evolving nature of the disease), general health condition (especially in older adults), associated deficits (cerebellar, sensory and cognitive; hemineglect) are considered together to arrive at a contract with patients and/or caregivers.

[Evolution of surgical indications in upper limb functional surgery for tetraplegic patients: Retrospective study of 428 procedures]. / Évolution des indications chirurgicales dans la chirurgie fonctionnelle du membre supérieur chez le patient tétraplégique : étude rétrospective à propos de 428 interventions.

INTRODUCTION: Regarding surgical strategy for upper limb functional rehabilitation in patients with traumatic tetraplegia, there are few publications and the case series are quite small. PATIENTS AND METHOD: We reviewed all traumatic quadriplegic patients, operated one by one surgeon, professor Marc Revol, for functional surgery of the upper limb in the same department from 1989 to 2018. For each patient, we recorded their gender, their group according to the international classification, their age at the time of the first surgical procedure, the length of time between the accident and the first surgery and between two procedures, the average duration of the whole surgical program, and the surgical technique used for the elbow, the wrist, the long fingers and the thumb. RESULTS: We reviewed 158 cases, representing 428 surgical procedures. Some surgical principles have remained unchanged through the years: the hand opening stage comes before the closing one, and systematically includes intrinsic active palliative procedures using lassos; and restoration of long fingers grasping is consistently associated with restoration of thumb gripping and with flexor tendons tenolysis in the lassos region. Other strategic points have evolved over time: restoration of active elbow extension now systematically uses the biceps over the deltoid transfer; brachio radialis (BR) to extensor digitorum communis (EDC) and to extensor pollicis longus (EPL) transfer has been replaced by tenodesis; in groups 2, 3, 4 and 5, the hand opening stage has been consistently associated with the biceps transfer, thus shortening the surgical program to two procedures instead of three for each upper limb; split distal flexor pollicis longus (FPL) tenodesis has replaced thumb arthrodesis; and, whenever it was possible, BR has been spared from group 3 and beyond. CONCLUSION: In groups 2 to 5, the indications have evolved towards the following strategy. The first surgical step includes restoration of elbow extension using biceps transfer and hand opening reinforcement through four lassos, one split distal FPL tenodesis for the thumb, and EDC and EPL tenodesis to the retinaculum. The second surgical procedure consists of restoration of long fingers and thumb flexion using one unique motor (BR or extensor carpi radialis longus), and closed tenolysis of the flexor tendons in case of adhesions in the lassos area.

Muscle recovery after ACL reconstruction with 4-strand semitendinosus graft harvested through either a posterior or anterior incision: a preliminary study.

INTRODUCTION: Harvesting of a 4-strand semitendinosis (ST4) graft during anterior cruciate ligament (ACL) reconstruction can be performed through either a posterior or anterior approach. The objective of this study was to evaluate the recovery of the quadriceps and hamstring muscles as a function of the graft harvesting method. We hypothesized that posterior harvesting (PH) would lead to better recovery in hamstring strength than anterior harvesting (AH). METHODS: In this prospective study, the semitendinosus was harvested through an anterior incision in the first group of patients and through a posterior one in the second group of patients. The patients were enrolled consecutively, without randomization. Isokinetic muscle testing was performed three and six months postoperative to determine the strength deficit in the quadriceps and hamstring muscles of the operated leg relative to the uninjured contralateral leg. RESULTS: Thirty-nine patients were included: 20 in the AH group and 19 in the PH group. The mean quadriceps strength deficit after three and six months was 42% and 26% for AH and 29% and 19% for the PH, respectively (P=0.01 after three months and P=0.16 after six months). The mean hamstring strength deficit after three and six months was 31% and 17% for AH and 23% and 15% for the PH, respectively (P=0.09 after three months and P=0.45 after six months). After three months, the PH group had recovered 12% more quadriceps muscle strength than the AH group (P=0.03). CONCLUSION: Our hypothesis was not confirmed. Harvesting of a ST4 graft for ACL reconstruction using a posterior approach led to better muscle strength recovery in the quadriceps only after three months. CASE CONTROL STUDY: Level 3.
