ABSTRACT
Elbow extension palsy is generally well tolerated, because when standing up, it is alleviated by gravity. In the case of trunk paralysis or brachial plexus palsy, standing is possible, thus the restoration of active elbow extension improves the hand's positioning above the shoulder, and allows the elbow to be locked in extension, which is necessary during certain activities such as cycling. In these palsy cases, the triceps brachii will be reinnervated by nerve transfers if surgery is performed early enough before irreversible atrophy of the effector muscle sets in. In these situations, secondary tendon transfers are rarely indicated. Few available muscles can be harvested without deleterious consequences on the donor site. Finally, in patients with a very deficient upper limb but with a healthy contralateral limb, when nerve transfers are no longer possible, elbow extension will not be restored. In the tetraplegics using a wheelchair, elbow extension becomes essential for positioning the hand in space and for potentiating the transferable muscles to activate the hand. As nerve transfers have rare indications and are currently being validated in this population, palliative tendon transfers are the reference technique. They must be integrated into an overall upper limb reconstructive surgery program that takes into consideration the potentially usable muscles and the presence of elbow flexion contracture and supination deformity of the forearm. Elbow extension restoration techniques are based on the transfer of two muscles, the posterior deltoid and the biceps brachii. The first is very effective and has very specific requirements, notably good anterior stabilization of the shoulder by the pectoralis major, while the second has broader indications, notably in the case of elbow contracture and inability to stabilize the shoulder anteriorly.

Ulnar paralysis has multiple clinical presentations, which are due to partial recovery or to anatomical variations between the ulnar and median nerves. The main sequelae of ulnar nerve paralysis are the loss of hand strength with impairment of all intrinsic functions of the fingers and some of the thumb's functions. Weakness of the adductor pollicis and flexor pollicis brevis muscles may manifest as weak key pinch with automatic flexion of the thumb interphalangeal joint when gripping. Indications for palliative surgery have decreased due to advances in peripheral nerve surgery. However, palliative surgery still has a significant role to play when nerve repair techniques are not indicated or do not provide satisfactory results. The principle is to reinforce metacarpophalangeal flexion while stabilizing the thumb's interphalangeal joint, thus supplementing the action of the flexor pollicis brevis. This is generally done by transferring the flexor digitorum superficialis tendon of the fourth finger to the distal insertion of the superficial thenar muscles and the extensor pollicis longus. Restoration of the first dorsal interosseous is more rarely indicated.

In addition to motor deficits, central nervous system disorders combine major alterations in the motor pattern with spasticity and over time, contractures. Their varied clinical presentation makes their assessment and the therapeutic strategy more complex. For these reasons, tendon transfers in this population will have more limited indications and above all, will have to be integrated into a complex surgical program combining other procedures such as tendon lengthening, selective neurotomies and joint stabilization. The surgical strategy is far from being obvious. When faced with clinical presentations having very different objectives-functional or comfort only-it is difficult at first sight to build a standardized surgical program. We therefore propose a method to evaluate these patients, thanks to a score (INOM) that integrates prognostic factors and parameters to be corrected surgically. Three components guide this program: a prognostic factor (proximal motor control of the shoulder and elbow), correction of abnormal limb postures and restoration of active elbow, wrist and finger extension. The surgical strategy can be constructed from the INOM score which establishes the priorities for care. Nerve blocks and botulinum toxin injections are essential tools for this analysis. They help distinguish between spasticity and contracture, and can unmask certain antagonistic muscles. A tendon transfer in this population will be just as effective by the function it restores as by the action it suppresses in a malpositioned limb. For each joint, we describe the indications for tendon transfers and their relative role among the techniques with which they must be combined.

Total wrist arthrodesis in severe wrist flexion deformities (greater than 60°) due to spasticity represents a valid therapeutic option. It aims to improve the hand's appearance, hygiene, function and to prevent the deformity from getting worse. The objective of this study is to evaluate the clinical and anatomical results of wrist shortening arthrodesis using a classic volar plate in the dorsal position in functional surgery for central spastic hands. We conducted a single-center analysis of a series of patients who underwent this shortening arthrodesis. The review at a minimum 1-year follow-up included a clinical evaluation (House score, INOM score, patient satisfaction and complications), and anatomical evaluation (arthrodesis position, bone healing and carpometacarpal arthropathy). Twenty-eight patients with a mean age of 40.6 years (18-74) were included at a mean follow-up of 30.6 months (12-75). The fusion rate was 100%. No carpometacarpal arthropathy was noted. The mean position of the fused wrist was 11° extension and 15° ulnar tilt. There were two complications (7%): one postoperative hematoma and one case of discomfort due to impingement that required plate removal. The House score was significantly improved postoperatively (2.4 (0-5) versus 1.8 (0-4), p < 0.001), as was the INOM score (45 (12-64) versus 63 (36-84), p < 0.001). The patient satisfaction rate was 93%. The use of a simple and common material (volar plate in dorsal position) during this challenging surgery (spastic wrist contracture), provides good anatomical results and high patient satisfaction. LEVEL OF EVIDENCE: Level 4, case series, therapeutic study.

Elbow flexion paralysis is one of most significant deficiencies in the upper limb. When secondary to brachial plexus palsy or nerve trunk lesions, restoration of elbow flexion by means of early nerve surgery or palliative transfers should be part of a comprehensive treatment plan. Tendon transfers are indicated in long-standing palsies, in those who are poor candidates for nerve surgery or when the results of nerve surgery are inadequate. A regional pedicled muscle transfer is performed if available. In this case, a "strong" donor is preferred (pectoralis major with pectoralis minor transfer, triceps brachii to biceps brachii transfer, or bipolar latissimus dorsi transfer). A "weak" transfer is indicated in patients who have incomplete recovery of elbow flexion (MRC 2 strength): isolated pectoralis minor transfer, medial epicondylar muscle transfer according to Steindler technique, or advancement of biceps brachii tendon on forearm. When no donor muscle is available, a free reinnervated muscle transfer may be indicated if age and nerve regeneration conditions are favorable.

The aim of our study is to describe the assessment of the upper limb in tetraplegic patients to follow his (her) neurological progression and to define the medical or surgical treatment program. We selected upper limb assessment tools and scales for tetraplegic patients described in the medical literature through a PubMed search over the last four decades. For each method, we present the implementation rules and its metrological properties, including its validity in French. We selected five clinical scales for functional evaluation of grasping, as well as four scales for evaluating the overall function of these patients. Finally, we identified three complementary precision assessment tools. The AIS (ASIA Impairment Scale) classification describes the level and the severity of the spinal cord lesion. The Giens classification is more practical for describing the upper limb in middle and low tetraplegia. Impairments can be assessed with most common generic scales and nonspecific measurement devices: range of motion, strength, sensory loss, spasticity, joint pain. Measurement of pinch and grip strength is widely used and easy to perform. The Capabilities of Upper Extremity (CUE) and the Jebsen Taylor Test are the best validated and usable scales. At a general functional level, the Spinal Cord Independence Measure (SCIM) is the most relevant scale in these patients. Motor nerve blocks, electromyography, movement analysis and echography are promising additional methods. Assessment of the upper limb of tetraplegic patients relies both on generic and specific assessment tools and scales.

Thumb metacarpophalangeal instability is commonly found in conjunction with trapeziometacarpal osteoarthritis. If not corrected, it can have detrimental effects on the outcome. The authors describe the two types of metacarpophalangeal deformities - hyperextension and valgus - their pathophysiology and the surgical repair techniques available to surgeons. An algorithm for treating this instability is presented.

Although distal radius fractures (DRF) are frequent, the management of associated ulnar styloid process (USP) lesions is still controversial. According to recent studies, a fracture of the USP does not appear to affect functional outcomes after treatment of a DRF with plate fixation. We sought to compare the impact of a USP fracture on pronation and supination strength in isometric and isokinetic tests. We included patients with a DRF who underwent volar locking plate fixation. We divided our population into three groups: one group consisted of patients who had a fracture of the USP base, one group composed of patients without USP fracture or with a distal ulnar fracture only, and a control group composed of subjects with normal wrists. Inclusion criteria included an age of 18 to 50 years and a minimum follow-up of 10 months post-surgery. The main exclusion criteria were complex intraarticular fractures and postoperative complications. The assessment was based on clinical examination and recording of forearm rotation strength during pronation and supination in isokinetic and isometric tests. The ratio between the operated and contralateral sides was compared for each patient. Thirty-six participants were included (mean age 31.1±4.5 years). The mean postoperative follow-up was 17.9±6.9 months. Participants with a USP fracture differed from other participants in their peak torque on the isokinetic test at 45°/s for pronation and supination, but not on isokinetic tests at 120°/s or in isometric tests. Isokinetic tests revealed a decrease in pronation-supination strength during sustained effort for patients with associated basal USP fractures. These findings may have clinical implications for management of the USP but need to be specified with further study. LEVEL OF EVIDENCE: prognostic study level III.

The aim of this study was to assess the clinical and radiographic outcomes after radioscapholunate (RSL) fusion for posttraumatic osteoarthritis. This was a retrospective, dual-center study of all patients who underwent RSL fusion between 1995 and 2015 for posttraumatic radiocarpal osteoarthritis. Patients were assessed at the final review to determine clinical (pain, wrist range of motion and strength), self-reported (QuickDASH, PRWE and MWS scores) and radiological (degenerative osteoarthritis in the scaphotrapeziotrapezoid (STT) or midcarpal joint and radiocarpal fusion) outcomes. We analyzed three groups: RSL fusion alone, RSL fusion with distal scaphoid excision (DSE) and RSL fusion with DSE and triquetrum excision (TE). Eighty-five patients were included; 10 were lost to follow-up and 11 required conversion to total wrist fusion before the final review. Finally, 64 patients had both clinical and radiographic evaluations. The mean follow-up was 9.1 years (range 1-21.4). RSL fusion alone was performed in 29 patients, RSL fusion with DSE in 23 and RSL fusion with DSE and TE in 12. At the final follow-up, the three groups did not differ in their pain or wrist motion. Overall, 47 (73%) patients were satisfied or very satisfied with the procedure. DSE significantly decreased STT osteoarthritis and radiocarpal non-union. The total wrist osteoarthritis rate after RSL fusion was 55%. RSL fusion is an effective procedure to preserve some motion in wrists with posttraumatic radiocarpal osteoarthritis. DSE prevents STT osteoarthritis by removing bony impingement and increases the fusion rate. LEVEL OF EVIDENCE: Level IV, Case series, Therapeutic studies.

Median nerve entrapment after supracondylar humeral fracture in children is rare. We report a case of Gartland type III supracondylar humeral fracture complicated by an entrapment of the median nerve following closed reduction and percutaneous pinning in a 5-year-old child. The diagnosis of entrapment was made 14 months post injury following progressive motor and sensory palsy. Resection and end-to-end suture were performed, leading to complete sensory and motor recovery eight months later. This nerve complication is often unnoticed and should be suspected systematically before and after reduction of all displaced supracondylar humeral fracture in children. The indication of resection-suture or nerve graft depends on the entrapment and the delay of the palsy.
ABSTRACT
The authors report a case of calcified glomus tumor of the shoulder in a 54-year-old woman. The nonspecific clinical findings and the noncharacteristic imaging results made diagnosis of this tumor impossible before surgery. The diagnosis was confirmed by a biopsy. The outcome after surgical resection was excellent.

INTRODUCTION: In hemiplegic patients with a spastic clenched fist deformity, one of the goals of surgery is to address the hygiene, nursing and appearance problems. Transfer of the flexor digitorum superficialis (FDS) to the flexor digitorum profundus (FDP), initially described by Braun and colleagues, opens the non-functional hand in these patients. The primary objective of our study was to confirm the effectiveness of this technique for correcting these deformities. The secondary objectives were to demonstrate potential functional gains and to identify potential complications. MATERIAL AND METHODS: A Braun procedure was performed in 26 patients (9 women, 17 men, ranging in age from 36 to 79 years). The overall appearance of the hand was graded using the Keenan classification system. Complications related to the surgery were documented. The hand's function was evaluated with the House score. RESULTS: The average follow-up was 47 months. Preoperatively, all patients had a class V hand: severe clenched-fist deformity with zero pulp-to-palm distance. Postoperatively, 10 patients had a type I hand (open hand, with less than 20° spontaneous extension deficit of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints) and 12 patients had a type II hand (20° to 40° spontaneous extension deficit of the MCP and PIP joints). The mean House score for all patients went from 0 to 0.88, and seven patients had functional improvements. Four patients had a forearm supination posture, 10 had intrinsic deformity with spontaneous MCP flexion and 6 had a swan-neck deformity. CONCLUSION: Superficialis-to-profundus tendon transfer (STP) provides satisfactory outcomes in terms of hand opening, with some patients also experiencing improved hand function. However, the complications cannot be ignored. LEVEL OF EVIDENCE: IV-retrospective or historical series.

The midcarpal joint can be classified into two anatomical types - Viegas type I and Viegas type II - based on the absence or presence of a medial facet for the hamate on the lunate (lunohamate facet). Type I is associated with a round capitate shape, which theoretically allows better congruence with the lunate fossa of the distal radius following proximal row carpectomy (PRC). This morphological feature has never been considered as a predictive factor of clinical outcome for this surgical procedure. This study aimed to compare the clinical and radiological outcomes of the two Viegas types following PRC. A retrospective single-center study was carried out on patients who underwent PRC for wrist osteoarthritis. Minimum follow-up was 2 years. Lunate type was determined based on preoperative CT arthrography. The clinical evaluation included range of motion (ROM) and strength as well as the functional DASH, Mayo Wrist scores and a VAS for pain. The outcome of radiocapitate osteoarthritis was assessed on plain radiographs. Forty patients were reviewed with a mean follow-up of 57 months. Twenty-one Viegas type I and 19 Viegas type II were identified on preoperative CT arthrography. The etiologies included 23 SLAC wrists (12 Viegas type I, 11 type II), 8 SNAC wrists (4 Viegas type I, 4 type II), 6 cases of Kienböck's disease (3 type IIIa, 3 type IIIb with 3 Viegas type I and 3 type II), 1 Preiser's disease and 2 cases of transscaphoid perilunate dislocation of the carpus. Patients with a Viegas type I lunate had significantly greater flexion-extension ROM: 83.5° vs. 71° (P=0.04) and radial deviation: 12° vs. 7° (P=0.013) than those with Viegas type II. However, three cases of complex regional pain syndrome (CRPS) were reported in the Viegas type II group vs. zero in the Viegas type I group. There were no differences between the two groups in terms of strength, functional scores or VAS pain. The outcome of radiocapitate osteoarthritis was similar in both groups. Considering the number of CRPS cases in the Viegas type II group and similar functional results in both groups, the worse outcomes of the Viegas type II patients in terms of ROM cannot be considered as clinically relevant. This comparative study does not provide a reasonable basis for concluding that Viegas type I patients are better candidates for PRC than Viegas type II patients.

INTRODUCTION: Coracoid bone graft transfer has become the gold standard in patients with recurrent anterior shoulder instability associated with bony defect. Several studies have shown that the main stabilizing component of this procedure is the sling effect by the conjoint tendon and the lower portion of subscapularis (SS). The purpose of this study was to determine whether a larger SS volume below the bone block was correlated to greater postoperative shoulder stability. MATERIALS AND METHODS: This prospective study included a cohort of patients who underwent open coracoid bone graft transfer for post-traumatic recurrent anterior shoulder instability. Forty patients were reviewed at 2 years with a clinical and CT scan evaluation. A correlation analysis assessed the relation between the SS volume index (ratio of SS volume below the bone block to volume over the bone block) and Rowe and Walch-Duplay instability scores. RESULTS: There exists a positive and significant correlation between SS volume index and postoperative Rowe score, r=0.37 (P=0.03). The same trend was observed for Walch-Duplay score without statistical significance. A larger inferior SS volume did not result in a limitation of external rotation, greater fatty infiltration, or malposition of the coracoid graft. CONCLUSION: A larger SS volume below the bone block is related to greater postoperative shoulder stability. We recommend performing the split in the middle of the SS or higher instead of the junction of the superior two-thirds and inferior one-third as usually reported. LEVEL OF EVIDENCE: III, prospective study.

Tendon transfers are carried out to restore functional deficits by rerouting the remaining intact muscles. Transfers are highly attractive in the context of hand surgery because of the possibility of restoring the patient's ability to grip. In palsy cases, tendon transfers are only used when a neurological procedure is contraindicated or has failed. The strategy used to restore function follows a common set of principles, no matter the nature of the deficit. The first step is to clearly distinguish between deficient muscles and muscles that could be transferred. Next, the type of palsy will dictate the scope of the program and the complexity of the gripping movements that can be restored. Based on this reasoning, a surgical strategy that matches the means (transferable muscles) with the objectives (functions to restore) will be established and clearly explained to the patient. Every paralyzed hand can be described using three parameters. 1) Deficient segments: wrist, thumb and long fingers; 2) mechanical performance of muscles groups being revived: high energy-wrist extension and finger flexion that require strong transfers with long excursion; low energy-wrist flexion and finger extension movements that are less demanding mechanically, because they can be accomplished through gravity alone in some cases; 3) condition of the two primary motors in the hand: extrinsics (flexors and extensors) and intrinsics (facilitator). No matter the type of palsy, the transfer surgery follows the same technical principles: exposure, release, fixation, tensioning and rehabilitation. By performing an in-depth analysis of each case and by following strict technical principles, tendon transfer surgery leads to reproducible results; this allows the surgeon to establish clear objectives for the patient preoperatively.

Adaptive carpal malalignment is the consequence of malunion of the distal radius. Since the radial metaphysis and capitate have to be aligned, any disorientation of the radial epiphysis will force the proximal carpal row to adapt, as it is the only mobile element. There are two types of adaptation depending where the compensative occurs: (1) midcarpal - leading to flexion between the lunate and capitate, with the lunate maintaining a normal relationship with the radial epiphysis axis; (2) radiocarpal - combining flexion and dorsal displacement of the lunate relative to the axis of the radial epiphysis, with the midcarpal joint remaining aligned. Clinically, adaptive carpal malalignment is not the first reason for consultation in cases of distal radius malunion. It occurs in cases of moderate deformity with preserved pronation-supination in a young patient who has good mobility. It generates dorsal pain that may be associated with a snapping sensation. The diagnosis requires strict lateral X-ray views. Over time, the wrist becomes stiff but analgesic and is often well tolerated functionally. This type of deformity has not been shown to lead to osteoarthritis. Osteotomy to correct the malunion is the only way to treat adaptive carpal malalignment in active young patients who have a mobile but painful wrist.

INTRODUCTION: Two-stage surgical reconstruction of the flexor tendons by the Hunter technique is the salvage option in case of old tears or a severely damaged fibro-osseous canal. HYPOTHESIS: The identification of poor prognostic factors during the assessment of injuries at presentation could help determine indications and predict failures. MATERIALS AND METHODS: We report a retrospective single center series of reconstruction of zone 2 of the flexor digitorum profundus of the long fingers between 2000 and 2012, in 22 patients, mean age 33 years old with a mean follow-up of 36.4 months. RESULTS: The total active range of motion (TAM) of the rays was 110° with a mean range of motion of the PIP and DIP of 71° and 39° respectively. Sixty-three percent of patients were satisfied and 73% returned to their professional activities. A group with good and fair results was determined based on the Strickland classification (68%, 15 patients, mean TAM 126°, mean QuickDASH 22.6) and a group with poor results (32%, 7 patients, mean TAM 77°, mean QuickDASH 43.4). The factors of a poor prognosis were associated injuries to the extensor apparatus, infection (phlegmon) (P=0.023) and joint injuries (P=0.09). DISCUSSION: There are no factors in the literature to predict a poor prognosis except for reconstruction of the flexor pollicis longus. A simplified procedure could provide better results in patients with associated injuries to the extensor apparatus, infection (phlegmon) or osteoarticular damage, in terms of the duration of physical therapy, additional surgery and overall socioeconomic cost. The results in the literature of superficialis finger reconstruction are significantly better (P<0.001). CONCLUSION: Although the Hunter technique is still the reference procedure for the reconstruction of flexor tendons, our study identified prognostic factors of poor functional results such as infection and associated extensor apparatus damage, which should orient the surgeon towards a simplified technique such as the superficialis finger procedure. LEVEL OF EVIDENCE: IV: retrospective study.

Total trapeziometacarpal (TMC) joint replacement is increasingly being performed for the treatment of basal joint arthritis. However, complications such as instability or loosening are also frequent with TMC ball-and-socket joint replacement. Management of these complications lacks consensus. The purpose of this study was to report the results of 12 cases of failed TMC joint replacement that were treated by trapeziectomy with ligament reconstruction and tendon interposition (LRTI) arthroplasty. The follow-up consisted of functional (numerical scale, DASH score, satisfaction), physical (range of motion, strength) and radiological (Barron and Eaton ratio measurement) assessments. At a mean follow-up of 21 months, 11 patients were satisfied or very satisfied after surgery. The mean pain score was 2/10 and the mean DASH score 30/100. Mean thumb palmar and radial abduction was 40°. Thumb opposition measured by the Kapandji technique was 9/10. The height ratio was slightly increased. Trapeziectomy with LRTI after TMC joint replacement appears to be an attractive salvage procedure.

BACKGROUND: Sarcoma rarely involves the hand or wrist. Extensive surgical excision is the current standard of care. At the extremities, such as the hand and wrist, limb-sparing surgery with reconstruction to provide optimal function is increasingly performed. A descriptive case-series study of 16 patients with sarcoma of the hand and wrist managed using limb-sparing surgery is reported here. MATERIAL AND METHODS: Of 19 patients with sarcoma of the hand or wrist treated between 1999 and 2012, 16 were managed using limb-sparing surgery. These were consecutive patients managed at a single-centre and studied retrospectively. The tumour involved the hand in 7 patients and the wrist in 9 patients. The procedure was primary in 6 patients, whereas 10 patients underwent secondary revision surgery. In 12 patients, reconstruction was performed for one or more of the following structures: nerves (n=2), tendons (n=3), bone (n=3), and/or skin (n=8). After surgical excision, the margins were R0 in 15 patients and R1 in 1 patient. At last follow-up, survival, pain, and function as reflected by the DASH and MSTS scores were assessed. RESULTS: After the median follow-up of 4.5years [1-13], 15 patients were alive with no local recurrence and 1 patient had lung metastases. Mean values were 18 [0-49] for the DASH score and 88.8% [53-100] for the MSTS score. DISCUSSION: Limb-sparing surgery reconciles the need to achieve complete tumour excision with the need to restore function. No limits should be placed on tumour excision, given the availability of effective reconstructive methods. The functional outcome depends on the tolerance of adjuvant treatments, most notably radiotherapy. LEVEL OF EVIDENCE: IV, retrospective study.

Extra-articular distal radius fractures in young active patients are typically the result of sport injuries or traffic accidents. Displaced fractures are less well tolerated in young patients than in older people, especially in terms of dorsal tilt and radial shortening. Non-surgical treatment is only indicated when the fracture is minimally or not displaced. No fracture fixation method is superior to another, however, the treatment goal is a rapid return to previous activities.
