My journey in hand surgery: combining patient care, clinical and basic science research

This review is about my clinical and research journey in hand surgery. The journey has been a worthwhile and meaningful one, especially when I felt there were areas I could influence management, whether this be rare cases, common conditions or where a suggested algorithm may be helpful. I also had the unique privilege of working with geneticists, which has resulted in clinical-pathological publications that could influence patient management, as shared from a clinician's perspective. It is hoped this article will inspire young clinician scientists to pursue a journey of collaboration with other researchers.

Hand Surgery in Saudi Arabia

Hand surgery is a unique field that incorporates multiple specialties, aiming to provide the patient with a best possible functional and aesthetic results. Hand surgeons deal with different pathologies that require skills in several aspects of surgery. The field of hand surgery has evolved significantly over the past decades across the globe. This specialty has also been evolving in Saudi Arabia over the past 25 years. Some of the services offered to patients include specialized centers for brachial plexus, peripheral nerve, and pediatric hand surgery as well as centers for work-related hand injuries. There has also been significant contribution to the hand surgery literature from the hand surgeons working in Saudi Arabia, with hundreds of papers published in journals pertaining to hand surgery, orthopedic surgery, and plastic surgery, as well as the publication of several novel mutations causing congenital hand defects in journals concerned with genetics. The recent approval of a hand and microsurgery fellowship program in Saudi Arabia will also help boost this field in the country and the region.

C5-8 neonatal brachial plexus palsy. Operative findings, reconstructive strategy and outcome

From 1998 to 2014, we performed primary brachial plexus repair in 260 children with neonatal brachial plexus palsy. Thirty-three presented with a C5-8 palsy and 24 were reviewed for this study. The surgical strategy was to focus on repairing the upper trunk. Secondary surgical procedures were performed in 21 patients, mainly for shoulder external rotation deficit or weak wrist extension. After a mean follow-up of 9.7 years (range 3 to 19), the median Mallet score for the shoulder was 9.5 and the mean Raimondi score for the hand was 3.3. Median active movement scale was 5, 7 and 5.5 for the deltoid, biceps and triceps, respectively. We conclude that primary C5-8 brachial plexus reconstruction provides restoration of elbow flexion and most patients have a sensitive and functional hand. We also found that secondary surgery to improve shoulder and wrist function is often necessary, which should initially be explained to the family.Level of evidence: IV.

Brachial plexus birth palsy: Management during the first year of life

Brachial plexus birth palsy (BPBP) is defined as an injury to any nerve root of the brachial plexus during difficult delivery. BPBP is relatively rare; its incidence has remained constant over the last few decades, mostly due to unpredictable risk factors, such as shoulder dystocia. Both diagnosis and assessment of spontaneous recovery is based on clinical examination. Electromyography is difficult to interpret in the newborn and is therefore not meaningful. MRI of the cervical spine requires sedation or general anesthesia. Searching for a pre-ganglion tear prior to surgery is indicted. Prognosis depends on the level of the injury (pre- or post-ganglion), size and severity of the post-ganglion tears, speed of recovery, and quality of initial management. Although spontaneous recovery is frequent, some children suffer various degrees of sequelae, up to complete loss of function of the affected upper limb. Recent publications have improved general knowledge and indications for surgery. However, some aspects, such as indication and timing of nerve repair continue to be debated.

The prognostic value of concurrent Horner syndrome in extended Erb obstetric brachial plexus palsy

Horner syndrome may be seen in infants with extended Erb obstetric brachial plexus palsy. However, its prognostic value in these infants has not been previously investigated. A total of 220 infants with extended Erb palsy were included and divided into 2 groups: group I (n = 209) were infants with extended Erb palsy without Horner syndrome, and group II (n = 11) were infants with extended Erb palsy and concurrent Horner syndrome. The rate of good spontaneous recovery of elbow flexion was 59% in group I and 27% in group II, and the difference was significant (P = .038). The rate of good spontaneous recovery of wrist extension was 61% in group I and 0% in group II, and the difference as highly significant (P < .0001). Concurrent Horner syndrome in infants with extended Erb palsy may be considered as a poor prognostic sign for recovery of the sixth and seventh cervical roots.

External Rotation Osteotomy of the Humerus to Salvage the Failed Latissimus Dorsi Transfer in Children With Erb Birth Palsy and Supple Congruent Shoulders

Management of the failed latissimus dorsi muscle transfer to restore shoulder external rotation has received little attention in the literature. We report on 6 children with Erb birth palsy and supple congruent shoulders and who underwent external rotation osteotomy to salvage a failed latissimus dorsi transfer. It is standard of care to do humerus osteotomies only to children with significant deformities of the glenohumeral joint. In the current article, the osteotomy was performed despite the presence of supple congruent shoulders because the osteotomy seemed the best and simplest option available. The functional outcome was satisfactory; with all patients reaching the occiput easily. Furthermore, there were improvement of the standing posture and improvement of the elbow flexion contracture. We conclude that the osteotomy procedure is a simple and effective option of management after a failed latissimus dorsi transfer.

Obstetric brachial plexus palsy following routine versus difficult deliveries

Previous bio-engineering studies showed that intrapartum peak forces applied by the clinician were lower in routine deliveries than difficult deliveries. A total of 751 cases of obstetric brachial plexus palsy were included and divided into two groups: group I (248 patients) were born following routine deliveries and group II (503 patients) were born following difficult deliveries. Both groups were compared regarding the type of palsy and the rate of good/poor spontaneous motor recovery from the palsy. Group I subjects were more likely to have upper Erb palsy whereas those in group II were more likely to develop total palsy (P < .0001). The percentage of newborns with poor functional recovery was significantly higher (P < .05) in group II with regards to shoulder, wrist, and hand function. It was concluded that higher peak forces applied by the clinician in difficult deliveries affect the type of obstetric brachial plexus palsy.

Median nerve to biceps nerve transfer to restore elbow flexion in obstetric brachial plexus palsy

Median nerve to biceps nerve transfer in the arm has been reported only in adults. The following paper reports on 10 cases of this transfer in obstetric brachial plexus palsy. All patients had upper palsy (ERb's or extended ERb's palsy) and presented to the author late (13-19 months of age) with poor or no recovery of elbow flexion. Following the nerve transfer, nine children recovered elbow flexion (a score of 6 in one child and a score of 7 in eight children by the Toronto scale). The remaining child did not recover elbow flexion.

Kinesio arm taping as prophylaxis against the development of Erb's Engram

An Erb’s Engram is a common debility that develops in recovering children with Erb’s palsy. The purpose of this study was to investigate the effect of kinesiotaping over the deltoid and the forearm on the development of proper upper extremity function in children recovering from Erb’s palsy. Thirty patients with Erb’s palsy participated for 3 months in this study and were equally divided into two groups; control group A and study group B. The two groups received the same designed physical therapy program, while group B along the program, received kinesiotaping over the deltoid and the forearm. The subjects were evaluated, pre and post-treatment, and scored functionally, using the Toronto Active Motion Scale, and objectively, using an EMG device utilized to obtain the percentages of degeneration of the deltoid and the biceps muscles. Post-treatment values of six out of nine measured variables, between the two groups, revealed significant difference in favor of group B. The obtained results strongly support the introduction of kinesiotaping of the deltoid and the forearm as an adjunct to the treatment program of Erb’s palsied children.
